Hidden Spring in the Small Pavilion

Summer vacation has arrived, and the weather is gradually getting warmer.

Sixteen-year-old Alan has just finished her first year of high school and will be starting her second year in the fall. Her fourteen-year-old brother, Acheng, has just finished his second year of junior high school.

Their home is a detached cottage surrounded by large trees. The cottage is shaded by the trees all day long, making it a bit dark, but much cooler than the other houses in the neighborhood that aren't shaded by trees.

The second floor was originally just a small attic used to store infrequently used items. Last fall, their father had a craftsman convert the attic into two small bedrooms, one for Alan and one for Acheng.

The renovated attic has a narrow, long corridor in the middle, with the bedrooms on either side. The bedroom door was made of two sliding, side-sliding panels. A narrow, elongated horizontal window opened at the top of the outer wall to allow for ventilation. At the end of the corridor was a simple bathroom with a sink and toilet. At the other end of the corridor was a staircase leading downstairs.

It was summer, and the attic was still quite stuffy at night. To help with air circulation, the attic bedroom doors were all pushed open to the left and right. The bedroom and corridor were already quite small; with the bedroom doors open, the siblings' beds were practically touching, less than three meters apart.

June 2000.

"Sister, are you asleep?" Ah-Cheng asked softly.

After summer arrived, Acheng faced a problem: a few months ago, he had started masturbating without any instruction. When the bedroom door was closed, he could freely stroke his penis and masturbate; but now the door was wide open, and his sister was just a few feet away on the opposite bed. He dared not easily expose his private secret.

"Sis, are you asleep?" Acheng asked softly again.

His sister did not respond.

Acheng pulled a thin sheet over his lower body, thinking about the naked Japanese female students in the adult magazine he had seen at his classmate Xiao Xu's place a couple of days ago, and began to masturbate. At the same time, he also opened his ears wide, remaining alert, listening to his sister's breathing.

Alan was 162 cm tall, weighed 45 kg, and had measurements of 34B-23-34. She had fair skin and a delicate appearance. Alan always felt her breasts weren't big enough. In fact, while not "busty," they were small, firm, and perky, quite beautiful, and still growing.

Cheng had recently started to feel aroused towards his sister. When she wasn't looking, he would secretly stare at her budding breasts or admire her round, protruding buttocks from behind.

Lately, a small tuft of shiny black pubic hair had sprouted at the base of his penis. He had grown rapidly in the past year; when he entered school last fall, he was only 163 cm tall, but now he was 169 cm, making him one of the tallest in his class. He weighed nearly 60 kg, and his penis was a full 14 cm long and very thick when aroused. He was quite handsome, looking like a fashionable pop star; if he could sing, he would definitely attract a large audience.

The siblings have always been very close. Alan is an excellent student, consistently ranking at the top of her class since elementary school. Acheng isn't as outstanding as his sister, but he's still decent, always within the top ten in his studies. He admires his sister greatly and is always obedient and compliant to her every whim.

Usually, Acheng goes upstairs to bed a little later than his sister. By the time he arrives, she's usually already asleep. With the bedroom door wide open in the heat, he can clearly see her small breasts rising under her thin nightgown when she lies on her back, instantly arousing him and causing his penis to harden.

Now, under the thin sheet, Acheng is rubbing his engorged penis up and down, imagining it penetrating the vagina of the Japanese schoolgirl in the magazine picture, thrusting in and out, sometimes slowly, sometimes quickly… His sister seems to be fast asleep. But for some reason, Ah Cheng always had a feeling that his sister wasn't really asleep.

A few minutes later, the pleasure came, and Ah Cheng used the small towel he had hidden under the pillow to wrap his glans and ejaculate. He had recently become quite experienced in using a towel to wrap his penis and ejaculate, so he wouldn't stain the sheets. In the morning, when he washed his hands, he would wash the small towel with soap and hang it on the clothesline in the bathroom to dry, so he could use it again that night.

For several days in a row, every night when he went upstairs, he found that his sister's sleeping posture was becoming more and more alluring. Sometimes the thin sheet was lifted up, revealing half of her fair and tender thigh; sometimes her pajamas were lifted up, revealing the triangle of panties between her legs, and he could clearly see the outline of the fleshy mound between her thighs and below her abdomen.

That night, Acheng discovered even more. His sister's bedsheet was half-open, revealing her fair and slender right leg. The right side of her nightgown was also open, exposing a small, pointed breast.

"So beautiful, so alluring!!"

Acheng's heart pounded, and his genitals immediately hardened. He stood at the doorway of his sister's bedroom, his eyes fixed on her exquisite small breasts. The pink nipples stood erect on her fair breasts, incredibly sexy. Although he had seen women's breasts in pictures before, this was the first time Acheng had ever seen real breasts. After

looking for a while, he felt a strong need, and his penis grew harder and harder. He immediately returned to his own bed, took out the small towel from under his pillow, and prepared to masturbate, but before he could even rub it, his swollen glans had already ejaculated.

The next day, Acheng recalled the series of lucky discoveries he had made over the past week. He also had some doubts; perhaps his sister was faking sleep, intentionally letting him see her beautiful body. He decided to test this and repay her kindness.

That night, he deliberately went to bed earlier than his sister, took off his underwear, and stroked his penis a few times until it became erect. He half-covered himself with the sheet, leaving his left leg and half of his hard genitals exposed.

After a while, he heard Alan come upstairs, so he pretended to be asleep. He opened his eyes slightly and saw his sister standing at the door, watching his erection. After a long while, she returned to her bed.

"Acheng, are you awake?" his sister asked softly, and Acheng, of course, continued to pretend to be asleep.

His sister covered herself with a thin sheet, and he saw her hand moving between her legs under the sheet, her beautiful eyes fixed on his penis… After a while, he pretended to naturally change his sleeping position, shifting slightly so that his entire penis sprang out, standing straight and erect like a towering pillar.

He heard his sister let out a low sigh, her breathing becoming heavy, and her hand moving faster… A few minutes later, she made an “uh…uh…” sound. He guessed that his sister must have reached orgasm, and she was trying her best to suppress the sound.

In the following days, the siblings tacitly took turns pretending to sleep half-naked, letting the other masturbate while watching. She exposed more and more of herself, both breasts were now visible to her brother. An

even more wonderful sight awaited him.

That day, Acheng came upstairs later than his sister. When he got up, he found her lying on her back with her eyes closed, only the sheet covering her upper body. The hem of her nightgown was lifted up, and she wasn't wearing any underwear! Her lower body was exposed, her legs together, with a plump, white, and exquisite vulva between them!

This was the first time Acheng had ever seen a real woman's vulva, and he was overjoyed.

There was a small patch of sparse, short, soft hair on her mons pubis, and the two labia majora below were plump, white, and swollen, smooth and hairless, with a pink cleft tightly between them, and what looked like glistening dew. Her legs were together, rubbing against each other slightly back and forth, and her labia majora slowly moved up and down with the movement of her thighs.

He stood at his sister's doorway, his eyes fixed on the swollen labia between her thighs for a full two minutes. Then he returned to his bedroom, lay naked on his side on the bed, facing his sister, his eyes fixed on her exposed genitals, his hand gripping his 14-centimeter-long, thick penis, rubbing it up and down rapidly…

The next day, A-Cheng came upstairs first. He lay naked on his back, pretending to be asleep with his eyes closed, but one hand gripped his erect penis, slowly stroking it up and down. This time it was A-Lan's turn. She stood at A-Cheng's doorway, staring at her brother's thick genitals. She reached out and masturbated between her vulva until she reached orgasm, then went back to bed.

For the next few nights, it was the same: the siblings would take turns lying on the bed with their eyes closed, exposing their genitals, and slowly manipulating them while the other watched and masturbated.

During the day, they both pretended nothing had happened, acting as usual. That night, things finally changed. When Acheng went upstairs, he found his sister lying naked on the bed, seemingly asleep. Her vulva appeared damp, her right index finger still inserted in her tightly closed opening, her right leg extended off the bed, her right calf dangling over the edge. This time,

Acheng didn't immediately return to his own bed. He went into his sister's room, stood by the bed, his thigh pressed against her dangling calf and knee, staring at her plump, white vulva. He pulled out his rock-hard penis and began rubbing it up and down.

After a while, his sister moved. She opened her beautiful eyes and gazed at her brother's swollen penis as he masturbated beside her bed. She gently rubbed her knees against his thighs, her fingers, inserted between his legs, began to wriggle, teasing the clitoris. He stroked his penis with his right hand, while his left hand caressed his sister's knees and calves. After a while, his hand moved to his sister's fair thighs above her knees, and it felt wonderful.

He couldn't hold back any longer and began to ejaculate, covering his sister's thighs with semen. She let out a soft sigh, and a large gush of translucent, warm nectar gushed from her vulva.

The following night, Acheng lay naked on the bed, stroking his penis. Alan stood naked beside her brother's bed, her thighs pressed against his outstretched left leg, her buttocks thrusting against the small hand covering her vulva… For the next few nights, the siblings took turns going to each other's beds, staring at each other's genitals, and masturbating simultaneously until they both reached orgasm.

Usually, the brother would ejaculate first, followed by the sister, who would then experience vaginal lubrication and reach orgasm. During these sexual encounters, the siblings never spoke a word. They remained silent, tacitly watching each other's naked bodies and masturbating together. Their walls were thin and poorly soundproofed, and their parents' bedroom was downstairs; they didn't want to make any noise that might arouse their parents' suspicion.
It was Saturday, and Mom and Dad had a business dinner and wouldn't be home until late at night. Like the previous days, Acheng stood in front of his sister's bed, masturbating while looking at her naked body, stroking her calves, knees, and thighs above the knees. This time, he was bolder, gradually moving his hand upwards along her thighs… His sister moaned, letting her brother caress her fair, tender thighs.

With his sister's tacit consent, Acheng moved even higher, his palms slightly sweaty, and soon he touched the inside of her fair, tender thigh, right next to her vulva. He then boldly moved his hand to cover her vulva. His sister's reaction was to slowly move her body towards the inside of the bed, making room for her brother to climb on.

He sensed the silent invitation and lay down beside his sister, slipping his right leg between her soft, white thighs. He could no longer suppress his love and longing for her, and without a word, he kissed her.

It was his first time kissing a woman, and her first time being kissed by a man. It wasn't a wet kiss, but like lovers in their first love, a light touch of lips, yet this contact was enough to ignite an even stronger passion in this virgin couple.

They embraced gently, their hands caressing each other's naked bodies. He began to gently stroke his sixteen-year-old sister's small, erect breasts, while she reached between his legs, her small hand grasping his precocious, hard penis, stroking it up and down.

Both of them let out pleasurable moans, their lips lightly pressed together in repeated tender kisses… Alan’s breasts were cone-shaped, soft and elastic. The younger brother caressed his sister’s tender breasts with one hand, while the other hand slipped between her thighs, cupping her plump vulva in his palm, his middle finger exploring the cleft between the two soft labia, teasing the love-scented opening.

The older sister wrapped one arm around her brother’s neck, gently stroking his back, while the other hand explored his entire penis, the swollen glans, the thick, hot shaft, and the bulging scrotum. They moaned, their lips remaining gently pressed together in a kiss.

From observing his sister's masturbation over the past few days, the younger brother had learned her preferences. He imitated her movements, gently rubbing her labia with his fingers, occasionally lightly inserting the tip of his index finger into her small opening, dipping it in the love juice from her eyes, and gently rubbing and swirling it around the entrance of her secret place.

"Ah... God... So beautiful... So comfortable... Don't stop... It feels better than touching myself..." the older sister whispered in her brother's ear, her delicate hand grasping his erect penis and stroking it faster.

Under the caress of his sister's soft hand, it wasn't long before Ah Cheng felt a tingling sensation in his glans, and hot semen gushed out like a cannonball, shooting onto his sister's breasts once, twice, three times, and then spreading all over her flat abdomen. Just then, he felt a warm liquid well up in his sister's eyes, wetting his entire palm. Alan also reached her climax.

After a while, Acheng recovered. "Sister, that felt so good, thank you, dear sister!" Acheng whispered to his sister.

"Brother, I felt so good too... A few days ago, when I touched myself there, I kept thinking, what would it feel like if you were touching me? Maybe it would feel even better!... Now I know, it's much better than I imagined..." Both of them were exhausted and fell asleep in each other's arms.

Late at night, their parents came home to find the siblings fast asleep, completely unaware. Fortunately, their parents didn't go upstairs to check.

The next night, Acheng went upstairs and went straight to his sister's bedroom, took off his underwear (he usually didn't wear a shirt to sleep in the summer heat), and lay down next to his naked sister. The older sister was waiting for him. They began to kiss and caress each other's bodies...

The younger brother's fingertips, dipped in the nectar secreted from his sister's eyes, gently stroked and swirled around her small entrance... The older sister let out a pleasurable moan...

Two minutes later, Alan whispered, "Put it in a little more."

He carefully squeezed his fingertips into his sister's tender opening, his fingertips immediately enveloped by the soft, moist flesh. Alan let out a soft cry: "Ah!... Brother... Just leave it there and don't move... Ah..."
In no time, Acheng felt warm, moist love juice flowing from his sister's vagina, the soft, wet flesh enveloping his fingertips, rhythmically opening and closing. He felt incredibly sexy, and his penis, which his sister was holding and stroking, immediately ejaculated.

The following night, as he carefully inserted his fingertip into her tight, slippery anus and rubbed it around, his sister arched her hips, her urine swallowing the first joint of his finger. She groaned, seemingly complaining, "Use two fingers!... Thicker... I want to feel it... It might be about the same size as your penis..."

Ah Cheng joined his middle and index fingers together and carefully inserted them into his sister's anus. It was too tight; he could only manage to insert about two centimeters of the tip of his finger. She began to tremble, uncontrollably thrusting her vulva, wanting more to be swallowed.

"Ah... So good!" his sister said. Her flesh clamped tightly on her brother's joined fingers. She kept twisting her hips and matching the rhythm of her twisting. She held her brother's cock tightly in her hands and moved it up and down. She gasped and asked, "Brother, does it look like I'm fucking your dick?"

"Sister... I don't know. I've never been fucked before... Oh, sister, you do it like this. It feels so good to me." After
a while, both siblings reached climax.

She picked up the hand he was inserting, put her index and middle fingers together, looked at them carefully, and said: "Brother, they are still not as thick as your cock. I really... really want... to insert your cock into mine and try it. I don't know what it will taste like... It's a pity that you are my biological brother, we can't do that..."

July 2000.

The siblings continued their sexual caress before going to bed. Every night, the younger brother would climb into his older sister's bed and gently kiss her soft, warm lips. The siblings would caress each other until they both reached orgasm.

Curiosity led them to a new experiment. This night, they lay facing each other on their sides. The older sister's hand tightly gripped her brother's hot, hard penis, and she actively pulled him closer. Their eyes met, silent, but both tacitly agreed to the next step.

She shifted her hips, and he adjusted his position accordingly. His erect penis was now at the gates, positioned between her thighs. She grasped his thick shaft, carefully rubbing the glans against the inside and outside of her wet labia. The direct contact of their genitals brought them both unprecedented pleasure…

Acheng felt his penis throbbing, almost about to ejaculate. His sister noticed too; she quickly lay on her back, spread her legs, and pulled her brother onto her, his glans pressing against her eye. Both felt a jolt, and simultaneously let out pleasurable moans.

"Ah…brother, so beautiful, so wonderful!" the sister gasped.

"Sister, I love you, you're unbelievably beautiful!" the brother murmured.

He began to thrust inward, half of his large glans already inside his sister's eye. Alan, alert, quickly shifted his hips, and his glans slipped out of her vaginal opening. His hard penis stood erect, and his sister pressed his buttocks down with her hands, thrusting her genitals forward. Her labia gripped the shaft, and the lower edge of his penis rubbed back and forth like a saw in the honey-scented crevice. They both felt incredibly good.

She whispered in his ear, "I also want you to go inside me... but you know we can't do that, we're siblings... isn't this also very comfortable?"

"Yes, sister..." Acheng always agreed with his sister's opinion, "but I really wish we weren't siblings... sister, I miss your tenderness so much..." The younger brother lay on top of his sister, pressing her breasts into two fleshy mounds.

She breathed heavily, her hips thrusting up and down, feeling the pleasure of his thick, hard penis rubbing against her labia and touching the small bud inside her cleft…

“Sis, I’m going to cum!”

She released her hands from his buttocks, and he lifted his upper body, his penis like a small cannon hidden between their legs, firing in rapid succession, ejaculating onto his sister’s breasts and lower abdomen, with a few drops landing on her face.

Every night in the attic during midsummer was filled with a strong sense of spring.

Although the siblings didn’t actually have intercourse, they had discovered many ways of making love beyond penetration: caressing, licking, oral sex, rubbing his penis against her vulva and outside her mouth… all of which brought them pleasure and satisfaction. They had repeatedly confided in each other how much they longed for real, physical intimacy, but they both knew it was a grave taboo, an incestuous crime of "sibling adultery" forbidden by law. They tried their best to restrain themselves and were extremely careful to keep it a secret, behaving normally in front of others during the day. Before

each sexual encounter with his sister, Ah-Cheng would place a large, dark-colored towel under her buttocks, washing it the next morning and hanging it to dry in their shared bathroom. This way, their parents never discovered any trace of their sexual activity.

The Creator created life. To ensure the continuation and perpetuation of life, the Creator has ingeniously arranged within the genes of every living being the intense desire for intercourse with the opposite sex. No man-made taboos can hinder this overwhelming natural force for the continuation of life.

That night, Ah-Cheng held his erect penis, the glistening purple glans gently rubbing up and down between his sister's smooth labia. "Sister, if you could insert it… just a little bit, I wonder how wonderful that would feel?!" the younger brother whispered.

"I've been thinking that too, it must be wonderful… but we can't do that, we're siblings… and I'm afraid of getting pregnant," the older sister replied softly.

"Can we try just once, just once? Just a little bit in, then pull it out right away. That way you definitely won't get pregnant."

"Shh...don't be loud...you're rubbing me so well..." The older sister moved her vulva, cooperating with her brother's rubbing: "As soon as you said you were going to put it in, I felt it coming..." He also felt very sexy, his penis rubbing back and forth in her vaginal opening faster, and soon both of them reached orgasm.
This was the last three days of July.

July 29th, Saturday.

In the afternoon, their parents had business to attend to in Taipei and wouldn't be back until Sunday afternoon.

That evening, the siblings went upstairs early. As soon as the older sister got into bed, Ah Cheng couldn't wait to pull down her small thong and wantonly grope her vulva. A few days ago was my sister's period. During her period, Alan was a little uncomfortable and wouldn't let Acheng touch her. Today, her period was finally over.

Acheng hadn't ejaculated for three days, and his genitals were still erect and very uncomfortable. Today, he seemed very eager. My sister was also in a good mood today, probably because her period was over and her parents weren't home, so she felt safe and bold enough to play with her brother.

She took off her bra, pushed her brother onto her bed so he was lying on his back, took off his underwear, lay on top of him, and pressed his hard penis into her cleft, twisting her hips to make his penis rub back and forth between her labia. She kissed him passionately, putting her tongue into his mouth and letting him suck on it.

She stopped kissing him and looked at her brother: "I've been wondering what it would feel like to go inside. Maybe we can try it today, just a little bit inside."

Ah Cheng was more than happy to oblige. The sister straddled her brother's lap, holding his erect penis, smearing the glans with nectar from her vulva, and inserted it into the small entrance. She aligned the angle and gently sat down, squeezing most of the glans into the wet opening.

"Ah!" she cried softly, "I can feel it going in!"

She rubbed her hips, moving up and down slightly, until the glans was fully inside, and both of them felt an intoxicating pleasure.

"Brother, it feels so good!"

"Sister, it's amazing!"

Her snow-white, round buttocks continued to rotate and press down. The tip of his penis, about five centimeters long, entered her vagina, but the glans encountered resistance and couldn't go any further. The sister stopped pressing down and began to rhythmically contract her vaginal walls, squeezing the penis that her brother had inserted. An inexplicable pleasure suddenly surged into Acheng's mind. He knew he was about to ejaculate, so he quickly pulled out his penis, and like a pump, his semen shot onto his sister's breasts and lower abdomen.

"That was amazing!" She rubbed her labia against her brother's still-erect penis after ejaculation. "Thank you, big-dicked brother! Now I know what it feels like to have a penis inside! It's so much better than rubbing against a stick outside! Right? But we'd better not do it again, it's too dangerous!"

"Yes, I almost ejaculated inside you." Ah-Cheng agreed with his sister.

The next evening, their parents came home. For the next few nights, the siblings returned to their previous "non-intercourse" sex routine.

August 2000.

August 5th, another Saturday.

That night, the sister lay on top of her brother, swaying her plump, white buttocks, her wet labia slowly and rhythmically grinding against Ah-Cheng's hard, erect penis. Slightly breathless, the older sister whispered in her younger brother's ear, "Brother, last time you only went in a little bit, it felt so good. Shall we do it again?"

Ah-Cheng excitedly agreed, "Of course! Sis, I'll be extra careful!" He grasped his erect penis, aligning it with his sister's vulva. She half-sat, half-squatted, positioning the glans against the entrance of her vagina. Adjusting the angle, she slowly lowered her hips, her small opening swallowing the entire glans.

"Ah! Even better than last time," she whispered to her brother.

Her vagina gripped his glans tightly, and after a few seconds, she began to rub her vulva. Ah-Cheng sensed his sister's increasing arousal, and her vulva becoming increasingly slippery. Alan murmured, "Last time it only went in a little bit... I think... this time I'll let it all the way in and see what it feels like."

"That's for the best! I'll tell you before I ejaculate, and then I'll pull it out immediately!" the younger brother said excitedly.

She slowly lowered her hips, his penis penetrating deeper and deeper. "Let's take it slow. Some experienced classmates told me that the first time is a little painful," the older sister said.

"Sis, don't rush, I don't want to hurt you!" the younger brother said worriedly.

He looked at his sister's swollen, red labia, translucent milky fluid seeping from between her labia, flowing down the rim of his penis; their pubic hair was already soaked.

He felt resistance at the head of his penis—it was his sister's hymen!

"Okay! Brother, lift up!" the older sister said, pressing her buttocks down at the same time.

The younger brother erected his penis, feeling the glans break through the barrier of his sister's vagina. He continued pushing, and in an instant, his entire penis was inside her!

"It doesn't hurt much; in fact, I feel great," the sister said.

Ah Cheng felt an indescribable pleasure, but he didn't forget his promise to his sister: "Sis, take it out quickly, I'm going to cum!"

She quickly raised her vulva, and as soon as his penis slipped out of the beautiful crevice that tightly enveloped it, it shot out thick, cloudy white semen like a pump. The shaft was covered in the oily liquid, with a few streaks of bright red blood.

"We finally did it, really!" "

Hmm, sis, I don't think this counts as real sex... My classmate said that sex is about the penis being inside and thrusting in and out at various angles. Real sex involves thrusting for a while, then the penis ejaculates inside, and both partners reach orgasm. It's not just about staying inside or pulling out and ejaculating outside... You know what I mean?"

The older sister said thoughtfully, "Yes, you're right, I understand. But that kind of sex is something siblings shouldn't do. We were just experimenting with the feeling of the penis inside, that's different from real sex, what we did doesn't count as sex..." Then she chuckled softly, "Brother, you've already taken my virginity, what do you say now?!"

"Sister, I love you! It's so wonderful, but the little bee hasn't had enough yet."

For the next few nights, they returned to their previous caressing and kissing ways. If his sister didn't ask for penetration, Ah Cheng would never force her; he would never do anything she didn't want to do. In fact, Ah Cheng knew he was incredibly lucky. Every night he could play with and lick his beautiful sister's soft, white breasts and plump vulva, caress her entire body, and rub his penis against her lovely genitals…

She even let him actually "penetrate" her once, her virginity… He believed none of his classmates were as fortunate as him.

August 9th, Wednesday.

Night fell. In the attic, Ah Cheng lay on his sister Ah Lan's soft, naked body, gently kissing her. He had now learned to avoid hurting his beloved sister. He supported most of his weight with his elbows and knees, his chest gently pressing against her breasts. Their lower abdomens were pressed together, and his engorged, hard penis rubbed back and forth in her wet, fleshy cleft. It repeatedly touched the budding flower bud peeking out from the crevice, and she let out a plaintive moan.

"Sister, you're so beautiful! I love you so much, sister!" the younger brother praised sincerely.

"Brother, you're so handsome!... My big cock, my good brother, I love you so much!" She thrust her vulva forward, moving in sync with her brother's hips, her delicate hands stroking his head and back: "Brother, I'm about to come. Can you do what you did last time and put your whole cock in? This time, stay inside a little longer so I can feel the sensation of your cock inside me."

He didn't say a word and immediately and gently complied. The sister spread her beautiful legs, raised her knees, and the head of her brother's cock aligned with her vaginal opening, thrusting his hips.

Ten seconds later, the fifteen-centimeter-long penis (yes! It had grown another centimeter since summer vacation!) was fully inserted into the sister's tight little hole. He felt the soft, wet walls trembling. He let it stay inside, motionless, and that feeling was wonderful!

"Brother, can we go in and out twice?... If we go in twice and then stop, that... it probably won't count as real sex." The older sister pleaded anxiously.

"Okay!" The younger brother immediately acted, slowly pulling his penis out completely, then quickly inserting it again, all the way in at once.

"Ah... ah... so good... I'm almost there..." The younger brother slowly pulled out completely again, then slowly inserted it all the way in. "

Ah... I'm coming... there's a big cock in my hole... I'm coming..." she cried out joyfully, her voice growing weaker and weaker, a warm, moist nectar flowing from her flower.

Acheng felt waves of pleasure emanating from the cock inserted in her vagina, but he tried his best to hold back, until the very last moment, when he quickly pulled out and ejaculated. The first two drops shot onto her sister's lips, the rest splashing onto her breasts and lower abdomen. She wiped the semen from her lips with the back of her hand, her breasts heaving, her heart racing, a happy smile on her face.

After a brief pause, she calmly said, "It was so amazing!... We almost... felt like we were really..."

"Sis, it seems to feel better and more comfortable each time. Last time I almost ejaculated inside you immediately, but this time I'm not as flustered or sensitive, and I can control myself better, but we still have to be very careful."

Recently, Ah-Cheng's stamina has improved significantly, and each time his sister reaches orgasm first. He only ejaculates after his sister has orgasmed once or twice.

"I know. We can only dream about it... We're siblings... You absolutely can't ejaculate inside... I'll get pregnant..."
A week later, the weather got hotter, and the siblings' passion intensified. Alan grew increasingly fond of her younger brother, Cheng. Her handsome and strong brother was gentle, dashing, and always so obedient to his sister.

She had already climaxed once, and she lay on top of him, her love-drenched lips gently rubbing his still-hard penis up and down.

She sat up, smiling at her brother. He held her white, tender buttocks, his penis erect like a rocket ready to launch, glistening with the slippery nectar from her previous climax. She moved her vulva, letting the glans rub against her labia, touching the small bud within.

The cleft was filled with a trickling fluid. This time, her vulva was raised slightly higher, and the purplish glans unexpectedly slid to the slightly sunken opening beneath the labia, the glans perfectly pressing against the small entrance. As soon as she sat down, the hard penis smoothly slid into her tight, slippery vagina.

Alan let out an "Oh," feeling both swollen and blissful. She gazed at her handsome brother, leaned down to give him a wet kiss, and twisted her hips. He immediately thrust his hips forward, allowing his penis to penetrate deeper. After a few thrusts, his penis was fully inserted, the glans pressing tightly against the soft flesh deep within his sister's clitoris.

She interrupted the kiss and whispered in her brother's ear, "I want to cum again. You can thrust like last time, but this time you can thrust more. Let's try what it really feels like to make love."

"Okay, sis, I'll stay longer this time and do it more times!"

"As long as you don't ejaculate inside me, it's okay to do it more times!"

Ah Cheng simply couldn't believe that his sexy and beautiful sister was actually going to make love to him, instead of just inserting without moving like the last two times, or having to pull out after two thrusts.

His sister's buttocks, which were on top of him, had begun to sway and wriggle, and he also began to slowly move his buttocks, coordinating with his sister's movements. His penis began to make a half-in, half-out piston motion in her tight, warm, and slippery little hole.

"Ah...ah...brother...so beautiful...I've never felt so good before..." the sister gasped. "It's amazing...ah...oh..."

From her expression and moans, Ah Cheng knew she was truly enjoying herself. She straddled him like a horse, and he reached out and pressed his hands against her firm, white buttocks, helping them rise and fall in sync with his erect penis. He felt her vagina was very tight, but thankfully it was very lubricated, which didn't hinder his thrusting.

Both of them closed their eyes, enjoying the wonderful sensation of each thrust... They gradually increased the depth of their movements and quickened the pace...

He opened his eyes to look at his sister; she had her eyes closed, her head slightly tilted back, her mouth slightly open, her pair of white breasts swaying up and down, and she was constantly emitting low moans of "ah...oh..."

After a while, suddenly...

"Ah ...

She lay limply on top of him, passionately kissing him. He took her delicate tongue in his mouth, and she let him suckle.

After a while, she said, "If you had ejaculated inside me just now, then we would have truly made love. I wonder how wonderful that would have felt? I really wish we could try it once… but that's too dangerous… absolutely not…" With that, she quickly fell into a deep sleep.

Ah Cheng had never ejaculated so comfortably before. The pleasure was incomparable to masturbation, or his sister stroking him, or even the feeling of ejaculating through friction on her vulva. The feeling of ejaculating after his penis had thrust deeply into his sister's flesh was so liberating and satisfying, completely different from the emptiness and loss he felt after masturbation.

He was tired too, so he embraced his sister and fell asleep. He completely forgot that his parents downstairs might come up to check and find the siblings naked and embracing in the same bed. Fortunately, his parents didn't come up to check.

The next day, both siblings felt a deep sense of guilt, realizing that they had "really" violated the taboo of incest. But driven by hormones, at night, they were once again locked in a passionate, naked embrace. There was no "penetration" or intercourse; just like before, they kissed, caressed, and rubbed... until they both reached climax, then fell asleep in each other's arms.

August 19th, Saturday.

That night, Ah Cheng lay gently on his sister's naked body, the two sharing a passionate kiss, their tongues locked in each other's. His sister pushed him off, straddling him, and once again held his thick, hard penis tightly between her wet labia, her eyes misty as she smiled at him.

"I've been thinking about how we made love a few days ago," she said softly. "It was so wonderful, so pleasurable. Why is something so beautiful called 'incest,' something we can't do? I keep thinking about making love with you like that again, about playing hard and pleasurable many times!" As she spoke, she grasped his erect penis with her delicate hand, guiding the glans into her vagina.

"Sister, I've also been wanting to make love with you to the fullest!" her brother replied excitedly.

The meat tightly held the ping-pong ball-sized glans, and her small tongue licked her brother's lips. He gently raised his hips, and the first half of his cock slid in and out of the juicy vagina. She bucked and twisted to match his thrusts... After a while, the small flesh hole swallowed up the entire fifteen centimeter long thick cock. He felt that her flesh hole was hot, tight and soft, the glans head pressed against a ball of tender meat, and his ball sac pressed against the curve of his sister's ass.

They paused for a moment to let the little one get used to the bulge inserted by the thick cock. Her vaginal walls involuntarily tightened and relaxed, tightened and relaxed... He felt his penis being squeezed by a tight, hot bag, and his shaft became harder and swollen accordingly...

After a while, the older sister got used to the penis invading her flower core, and she leaned down to kiss his mouth and cheek. She raised her jade buttocks, letting the penis slowly withdraw. "Pop!" The glans slipped out of the tightly gripping vaginal opening, making a crisp sound.

The younger brother's hard penis brought the older sister an indescribable pleasure, and she immediately grabbed the big rod, stuffed it back into her tender vaginal opening, and thrust her hips to let it go all the way in.

They repeated this several times, and then quickened the rhythm of their thrusting. He no longer allowed his penis to completely separate from her vagina, keeping the glans inside each time he withdrew before inserting it fully again…

Both were immersed in the pleasure of their genitals rubbing together. He thrust his erect penis in and out of his sister's tight, warm, and moist vagina again and again… Her legs were tightly wrapped around her brother's waist and hips, she leaned down, her breasts pressed against his chest, her arms tightly embracing him, her buttocks moving up and down rapidly.

They made love wildly and passionately. At this moment, in their senses, everything else in the world ceased to exist; only they, the brother and sister, were immersed in wonderful carnal desire, intimately united as one.

"I'm about to come!" the sister gasped.

The younger brother intensified his thrusts, his glans plunging deep inside, slamming against the soft flesh of her clitoris.

"Oh...oh...ah...it's so sore..." the older sister cried out, a large gush of warm, moist fluid gushing from her clitoris, making her already wet vaginal canal even more slippery.

Hearing his sister's cry of "sour," Ah Cheng's glans also felt a strange tingling and itching sensation. He knew he was about to ejaculate. "Sis, I'm going to cum, pull out quickly..." Ah Cheng tried to push his sister off him and pull his penis out.

The older sister opened her beautiful eyes, gazed at Ah Cheng, and excitedly said, "Shoot inside! Shoot inside my sister!"
Her jade arms tightly embraced him, her thighs clamped around his waist, and she thrust her vulva forward, locking the man's penis deeply inserted into her vagina. Her delicate tongue darted into her brother's mouth, eagerly urging him to suckle.

He eagerly took his sister's tongue into his mouth, greedily sucking, his penis swelling even thicker and longer, feeling it swell to an unprecedented length and hardness. Under his sister's thrusting, he felt his engorged glans squeeze into the crevice of her soft flesh, breaking through the bottleneck of the soft flesh.

"Oh...yo...yoyoyo..." the older sister cried out in ecstasy. Ah Cheng quickly sealed her cherry-like mouth with his lips, suppressing her cries to the lowest possible level.

His glans felt an intense tingling sensation, and he couldn't hold back any longer. His urethral opening throbbed once, twice, three times, four times, five times... and hot semen gushed out, spraying all over his sister's uterus.

A while after ejaculating, his penis returned to its original size, softening slightly, but still semi-erect. The siblings remained tightly embracing each other, both covered in sweat. She smiled lovingly at him, and they shared a sweet, wet kiss. Her buttocks continued to slowly rub and sway, her vaginal walls opening and closing, as if trying to suck up the last drop of semen from her brother's penis.

After a long while, the siblings drifted into a sweet dream. She remained lying on top of him, his genitals softened and slipped out of her vagina, the still-thick shaft lying between her slippery labia, the glans pressed against her moist, sparse pubic hair.

The next morning at eight o'clock, their mother called from downstairs, "Alan, Cheng, why aren't you up yet? Breakfast is getting cold!"

The siblings awoke from their deep sleep. Their eyes met, both feeling conflicted: they had experienced unprecedented satisfaction the previous night, but deep down they were also filled with a sense of guilt. Cheng felt guilty for having ejaculated "really" deep inside his sister's vagina and dared not look her in the eye; Alan also felt an indescribable unease.

"Let's talk tonight. Maybe we shouldn't be doing this, we can't continue like this..." Alan said with some remorse.
Three days ago, his sister started her period, and Acheng hadn't had sex for three days. Today, his sister was "clean," so he took off his own clothes and removed his sister's underwear, starting to fondle her breasts and vulva.

The first volume of the comic tells the story of three high school girls and their boyfriends going to a lakeside, only to be seen by three escaped convicts hiding in the woods by the lake. With no one else around, the three men threatened the three boys with knives, tied them to trees in the woods, and ordered the girls to take off their underwear and trousers, lewdly fondling their breasts and vulvas. First, they forced the girls to perform oral sex and suck their penises. Then, each man grabbed a girl and raped her vagina in front of their boyfriends, venting his lust. Then they switched partners, gang-raping the three innocent female students in various positions. Each of them was gang-raped four or five times, and also sodomized once, their genitals a mess, their vulvas swollen and bruised… The illustrations were very realistic and vivid, especially the exaggerated close-ups of the large penises forcibly penetrating the vaginas, which were incredibly lifelike and arousing.

Before she had even finished reading the first volume, the older sister threw down the book, her voice hoarse, and said urgently, “Brother, come and rape your sister! Like the men raping girls in these comics…”

Acheng imitated every pose from the comics, passionately ravaging his sister's tender flesh...

After two hours of "simulated rape" by his younger brother, Acheng ejaculated into his sister's vagina four times. His sister's body went limp, her beautiful eyes closed, and she fell peacefully asleep.

After resting for a while, Acheng put on his clothes and hurried to Xiao Xu's house to return the books.

As soon as Acheng left home, his mother returned. After shopping this afternoon, she didn't go back to the store but went straight home, three hours earlier than usual. Holding the 34C bra she had just bought for Alan, she went upstairs to put it on her daughter's bed.

The scene before her eyes shocked her. The daughter lay naked on her back on the bed, legs spread wide, a large towel placed under her buttocks, covered in a mess of fluids. Thick, sticky fluid clung to her vulva and between her thighs, and a semi-transparent, cloudy discharge continued to seep from her opening.

"Ah! Alan was home alone and was raped by a bad man!" The mother came to her daughter's side, gently shaking her head: "Alan, wake up... what happened?"

Alan's reaction shocked her even more. In her drowsy state, Alan didn't hear her mother's voice clearly, thinking it was her younger brother returning: "Brother, you were really good today, you're getting better and better... I was almost raped to death by you..."

The mother, Jian Yi, couldn't believe her ears. Was it Acheng who did it? Judging from their tone, they had probably done it many times already; no wonder there were so many traces of semen and vaginal fluid on the sheets a few days ago.

"Alan, get up!"

Opening her beautiful eyes, Alan finally recognized her mother. She was both ashamed and anxious, and covered her face, crying.

"Get up, put on your clothes, and tell your mother what happened," her mother said, both angry and concerned.

Alan sobbed as she told her mother about her relationship with Acheng, repeatedly emphasizing that it was her fault, not her brother Acheng's. He hadn't forced himself on her; she had fallen in love with him involuntarily and had sex with him.

After some calm reflection, the mother hugged her beloved daughter and said, "Alan, since you've already done it, there's no use in regretting it. The most important thing is that your brother can't get you pregnant; that would be truly hopeless. And we can't let Dad find out either. If he gets angry and makes a scene, our happy little family will be finished..."

"Mom, I'm so unfilial for doing something like this with my brother. I'm so sorry... I've tried desperately to stop having sex with my brother, but for some reason, I just can't control myself..."

"Alan, you haven't gotten pregnant yet, and only you, me, and Cheng know about your relationship with your brother. Thankfully, nothing terrible has happened. I just want to ask you, do you want to cut ties completely with Cheng, or will you still be unable to resist, maintaining a lingering connection, stopping today and doing it again tomorrow? I know that during adolescence, sexual desire and emotions are the hardest to control! I've had the same experience."

"Mom, to be honest, I love Cheng so much... I always want to have sex with him... I'm afraid I can't break it off!... Mom, thank you for being so understanding and forgiving... Mom, you said you've had the same experience?!"

"That's a secret, only you and I can know... You can't tell anyone, including Cheng."

"Mom, I promise I won't tell anyone!" Alan said.

"My first time was with your uncle... I was about your age then... Our relationship has continued until now. Maybe you have my genes, like loving to have sex with your brother..."

Alan's mother is 34 years old, fair-skinned and beautiful. She has only one brother and no other siblings.
Alan's uncle is 33 years old, a very handsome man, unmarried, and runs a chain of stores in the north, owning a McDonald's. He visits them every month, or his mother visits him.

"Ah! Mommy! You two are so great!... Tell me your secret love story, okay? Does Daddy know about you and Uncle?" Alan asked excitedly.

"I'll tell you more about my secret sexual relationship with your uncle later. Before our marriage, your father and I each had regular sexual partners, but they were all lovers with whom we couldn't officially marry... When we got married, we made a secret agreement: he could continue to have that lover who couldn't marry him, but who would never interfere with our marriage or relationship, and so could I. But we also agreed that no one else would be allowed to get involved." "

Who is Dad's secret lover?" Alan asked curiously.

"I can't say, it's a promise your father and I made." Mom changed the subject: "If you want to continue being with Acheng, you must keep it a secret, be careful, and absolutely cannot get pregnant now. You're still a high school student, that would ruin your future. Has Acheng been using condoms? I'll buy you birth control pills starting tomorrow, take them on time... You like Acheng so much, is he good in bed? Does he want a lot?" Mom asked.

Alan was deeply grateful for her mother's support and love, and of course she could be open and honest with her mother.

"Ah Cheng said he doesn't want to wear a condom, because it would reduce the feeling of real penetration and friction... He's very strong, he wants a lot, and he's getting stronger and stronger. At first, he ejaculated before me, but now he only ejaculates once after I've ejaculated several times. Each time he goes at it for a long time, and I'm almost dying from his penetration... yet there's an indescribable pleasure..."

"Hmm, 'like uncle, like nephew,' that's absolutely true!" Mom looked at her daughter, revealing a mysterious and knowing smile.

Alan was almost certain that her father's secret mistress must be her beautiful and sexy aunt, her father's only sister, who was three years younger than him.

That night, Ah Cheng's penis was deeply inserted into his sister's tender flower, and his sister twisted her jade buttocks, letting out a sick moan from her throat. The younger brother held his sister's two plump and pointed breasts, taking turns tasting them. Alan didn't tell her younger brother about her conversation with their mother that afternoon; it was a secret agreement between them. However, she did tell him that for safety, she would be taking her birth control pills regularly.

School started, and both siblings were busy with homework every day. They managed to sneak in some time for a romantic encounter an average of twice a week.

The semester ended, and the older sister remained at the top of her class as usual. Unexpectedly, Acheng's grades improved significantly, rising from ninth or tenth place to second. The teachers all said he was "single-minded," never fooling around with girls, and was a model student in the school, excelling in character, academics, and physical education.

The father was very satisfied with his son and daughter's academic performance. He also noticed that his daughter was becoming increasingly beautiful, especially her breasts, which were full, firm, and particularly eye-catching.

"My daughter really looks like a grown-up now, just like her mother. Hmm...and a bit like my little sister too..." the father thought to himself.

He thought that now that his daughter was older, perhaps he should give her a larger, more proper "bedroom." He considered renovating his downstairs "office" to serve as his daughter's boudoir.

He made this suggestion at the dinner table. Surprisingly, his daughter said that her current bedroom was perfectly fine and there was no need to move downstairs.

Mother said, "Alan lives upstairs, and she's always been doing fine. I think it's okay as usual!" Then, out of Father's sight, she winked and smiled at her daughter.

February 2001.

Although it was still chilly outside, spring was in full bloom in the attic. The older sister's long, white legs were spread apart, her knees bent and raised high; the younger brother stood before her bed, his upper body pressing against her pert breasts, his 16-centimeter-long, thick penis, its veins bulging, rhythmically thrusting in and out of her tight, wet vagina. Their pubic hair was soaked, the pink flesh of their vaginal openings rolled in and out with each thrust of the hard penis, and the area between the sister's white thighs was a pool of slippery fluid... The sister's arms embraced her brother, her small hands stroking his back, her beautiful eyes closed, enjoying the powerful force of his thrusts and the tender kisses above.

The attic echoed with the sister's plaintive moans, the brother's heavy breathing, and the squelching sounds of their genitals rubbing together.
(The End)

Summer vacation arrived, and the weather gradually warmed up.

Sixteen-year-old Alan has just finished her first year of high school and will be starting her second year in the fall. Her fourteen-year-old brother, Acheng, has just finished his second year of junior high.

Their home is a detached cottage surrounded by large trees. The cottage is always shaded by the trees, making it a bit dark, but much cooler than the other houses in the neighborhood without shade.

The second floor was originally just a small attic used for storing infrequently used items. Last fall, their father had a craftsman convert the attic into two small bedrooms, one for Alan and one for Acheng.

The renovated attic has a narrow, long corridor in the middle, with the bedrooms on either side. The bedroom door was made of two sliding, side-sliding panels. A narrow, elongated horizontal window opened at the top of the outer wall to allow for ventilation. At the end of the corridor was a simple bathroom with a sink and toilet. At the other end of the corridor was a staircase leading downstairs.

It was summer, and the attic was still quite stuffy at night. To help with air circulation, the attic bedroom doors were all pushed open to the sides. The bedroom and corridor were already quite small; with the bedroom doors open, the siblings' beds were practically touching, less than three meters apart.

June 2000.

"Sister, are you asleep?" Ah-Cheng asked softly.

After summer arrived, Acheng faced a problem: a few months ago, he had started masturbating without any instruction. When the bedroom door was closed, he could freely stroke his penis and masturbate; but now the door was wide open, and his sister was just a few feet away on the opposite bed. He dared not easily expose his private secret.

"Sis, are you asleep?" Acheng asked softly again.

His sister did not respond.

Acheng pulled a thin sheet over his lower body, thinking about the naked Japanese female students in the adult magazine he had seen at his classmate Xiao Xu's place a couple of days ago, and began to masturbate. At the same time, he also opened his ears wide, remaining alert, listening to his sister's breathing.

Alan was 162 cm tall, weighed 45 kg, and had measurements of 34B-23-34. She had fair skin and a delicate appearance. Alan always felt her breasts weren't big enough. In fact, while not "busty," they were small, firm, and perky, quite beautiful, and still growing.

Cheng had recently started to feel aroused towards his sister. When she wasn't looking, he would secretly stare at her budding breasts or admire her round, protruding buttocks from behind.

Lately, a small tuft of shiny black pubic hair had sprouted at the base of his penis. He had grown rapidly in the past year; when he entered school last fall, he was only 163 cm tall, but now he was 169 cm, making him one of the tallest in his class. He weighed nearly 60 kg, and his penis was a full 14 cm long and very thick when aroused. He was quite handsome, looking like a fashionable pop star; if he could sing, he would definitely attract a large audience.

The siblings have always been very close. Alan is an excellent student, consistently ranking at the top of her class since elementary school. Acheng isn't as outstanding as his sister, but he's still decent, always within the top ten in his studies. He admires his sister greatly and is always obedient and compliant to her every whim.

Usually, Acheng goes upstairs to bed a little later than his sister. By the time he arrives, she's usually already asleep. With the bedroom door wide open in the heat, he can clearly see her small breasts rising under her thin nightgown when she lies on her back, instantly arousing him and causing his penis to harden.

Now, under the thin sheet, Acheng is rubbing his engorged penis up and down, imagining it penetrating the vagina of the Japanese schoolgirl in the magazine picture, thrusting in and out, sometimes slowly, sometimes quickly… His sister seems to be fast asleep. But for some reason, Ah Cheng always had a feeling that his sister wasn't really asleep.

A few minutes later, the pleasure came, and Ah Cheng used the small towel he had hidden under the pillow to wrap his glans and ejaculate. He had recently become quite experienced in using a towel to wrap his penis and ejaculate, so he wouldn't stain the sheets. In the morning, when he washed his hands, he would wash the small towel with soap and hang it on the clothesline in the bathroom to dry, so he could use it again that night.

For several days in a row, every night when he went upstairs, he found that his sister's sleeping posture was becoming more and more alluring. Sometimes the thin sheet was lifted up, revealing half of her fair and tender thigh; sometimes her pajamas were lifted up, revealing the triangle of panties between her legs, and he could clearly see the outline of the fleshy mound between her thighs and below her abdomen.

That night, Acheng discovered even more. His sister's bedsheet was half-open, revealing her fair and slender right leg. The right side of her nightgown was also open, exposing a small, pointed breast.

"So beautiful, so alluring!!"

Acheng's heart pounded, and his genitals immediately hardened. He stood at the doorway of his sister's bedroom, his eyes fixed on her exquisite small breasts. The pink nipples stood erect on her fair breasts, incredibly sexy. Although he had seen women's breasts in pictures before, this was the first time Acheng had ever seen real breasts. After

looking for a while, he felt a strong need, and his penis grew harder and harder. He immediately returned to his own bed, took out the small towel from under his pillow, and prepared to masturbate, but before he could even rub it, his swollen glans had already ejaculated.

The next day, Acheng recalled the series of lucky discoveries he had made over the past week. He also had some doubts; perhaps his sister was faking sleep, intentionally letting him see her beautiful body. He decided to test this and repay her kindness.

That night, he deliberately went to bed earlier than his sister, took off his underwear, and stroked his penis a few times until it became erect. He half-covered himself with the sheet, leaving his left leg and half of his hard genitals exposed.

After a while, he heard Alan come upstairs, so he pretended to be asleep. He opened his eyes slightly and saw his sister standing at the door, watching his erection. After a long while, she returned to her bed.

"Acheng, are you awake?" his sister asked softly, and Acheng, of course, continued to pretend to be asleep.

His sister covered herself with a thin sheet, and he saw her hand moving between her legs under the sheet, her beautiful eyes fixed on his penis… After a while, he pretended to naturally change his sleeping position, shifting slightly so that his entire penis sprang out, standing straight and erect like a towering pillar.

He heard his sister let out a low sigh, her breathing becoming heavy, and her hand moving faster… A few minutes later, she made an “uh…uh…” sound. He guessed that his sister must have reached orgasm, and she was trying her best to suppress the sound.

In the following days, the siblings tacitly took turns pretending to sleep half-naked, letting the other masturbate while watching. She exposed more and more of herself, both breasts were now visible to her brother. An

even more wonderful sight awaited him.

That day, Acheng came upstairs later than his sister. When he got up, he found her lying on her back with her eyes closed, only the sheet covering her upper body. The hem of her nightgown was lifted up, and she wasn't wearing any underwear! Her lower body was exposed, her legs together, with a plump, white, and exquisite vulva between them!

This was the first time Acheng had ever seen a real woman's vulva, and he was overjoyed.

There was a small patch of sparse, short, soft hair on her mons pubis, and the two labia majora below were plump, white, and swollen, smooth and hairless, with a pink cleft tightly between them, and what looked like glistening dew. Her legs were together, rubbing against each other slightly back and forth, and her labia majora slowly moved up and down with the movement of her thighs.

He stood at his sister's doorway, his eyes fixed on the swollen labia between her thighs for a full two minutes. Then he returned to his bedroom, lay naked on his side on the bed, facing his sister, his eyes fixed on her exposed genitals, his hand gripping his 14-centimeter-long, thick penis, rubbing it up and down rapidly…

The next day, A-Cheng came upstairs first. He lay naked on his back, pretending to be asleep with his eyes closed, but one hand gripped his erect penis, slowly stroking it up and down. This time it was A-Lan's turn. She stood at A-Cheng's doorway, staring at her brother's thick genitals. She reached out and masturbated between her vulva until she reached orgasm, then went back to bed.

For the next few nights, it was the same: the siblings would take turns lying on the bed with their eyes closed, exposing their genitals, and slowly manipulating them while the other watched and masturbated.

During the day, they both pretended nothing had happened, acting as usual. That night, things finally changed. When Acheng went upstairs, he found his sister lying naked on the bed, seemingly asleep. Her vulva appeared damp, her right index finger still inserted in her tightly closed opening, her right leg extended off the bed, her right calf dangling over the edge. This time,

Acheng didn't immediately return to his own bed. He went into his sister's room, stood by the bed, his thigh pressed against her dangling calf and knee, staring at her plump, white vulva. He pulled out his rock-hard penis and began rubbing it up and down.

After a while, his sister moved. She opened her beautiful eyes and gazed at her brother's swollen penis as he masturbated beside her bed. She gently rubbed her knees against his thighs, her fingers, inserted between his legs, began to wriggle, teasing the clitoris. He stroked his penis with his right hand, while his left hand caressed his sister's knees and calves. After a while, his hand moved to his sister's fair thighs above her knees, and it felt wonderful.

He couldn't hold back any longer and began to ejaculate, covering his sister's thighs with semen. She let out a soft sigh, and a large gush of translucent, warm nectar gushed from her vulva.

The following night, Acheng lay naked on the bed, stroking his penis. Alan stood naked beside her brother's bed, her thighs pressed against his outstretched left leg, her buttocks thrusting against the small hand covering her vulva… For the next few nights, the siblings took turns going to each other's beds, staring at each other's genitals, and masturbating simultaneously until they both reached orgasm.

Usually, the brother would ejaculate first, followed by the sister, who would then experience vaginal lubrication and reach orgasm. During these sexual encounters, the siblings never spoke a word. They remained silent, tacitly watching each other's naked bodies and masturbating together. Their walls were thin and poorly soundproofed, and their parents' bedroom was downstairs; they didn't want to make any noise that might arouse their parents' suspicion.
It was Saturday, and Mom and Dad had a business dinner and wouldn't be home until late at night. Like the previous days, Acheng stood in front of his sister's bed, masturbating while looking at her naked body, stroking her calves, knees, and thighs above the knees. This time, he was bolder, gradually moving his hand upwards along her thighs… His sister moaned, letting her brother caress her fair, tender thighs.

With his sister's tacit consent, Acheng moved even higher, his palms slightly sweaty, and soon he touched the inside of her fair, tender thigh, right next to her vulva. He then boldly moved his hand to cover her vulva. His sister's reaction was to slowly move her body towards the inside of the bed, making room for her brother to climb on.

He sensed the silent invitation and lay down beside his sister, slipping his right leg between her soft, white thighs. He could no longer suppress his love and longing for her, and without a word, he kissed her.

It was his first time kissing a woman, and her first time being kissed by a man. It wasn't a wet kiss, but like lovers in their first love, a light touch of lips, yet this contact was enough to ignite an even stronger passion in this virgin couple.

They embraced gently, their hands caressing each other's naked bodies. He began to gently stroke his sixteen-year-old sister's small, erect breasts, while she reached between his legs, her small hand grasping his precocious, hard penis, stroking it up and down.

Both of them let out pleasurable moans, their lips lightly pressed together in repeated tender kisses… Alan’s breasts were cone-shaped, soft and elastic. The younger brother caressed his sister’s tender breasts with one hand, while the other hand slipped between her thighs, cupping her plump vulva in his palm, his middle finger exploring the cleft between the two soft labia, teasing the love-scented opening.

The older sister wrapped one arm around her brother’s neck, gently stroking his back, while the other hand explored his entire penis, the swollen glans, the thick, hot shaft, and the bulging scrotum. They moaned, their lips remaining gently pressed together in a kiss.

From observing his sister's masturbation over the past few days, the younger brother had learned her preferences. He imitated her movements, gently rubbing her labia with his fingers, occasionally lightly inserting the tip of his index finger into her small opening, dipping it in the love juice from her eyes, and gently rubbing and swirling it around the entrance of her secret place.

"Ah... God... So beautiful... So comfortable... Don't stop... It feels better than touching myself..." the older sister whispered in her brother's ear, her delicate hand grasping his erect penis and stroking it faster.

Under the caress of his sister's soft hand, it wasn't long before Ah Cheng felt a tingling sensation in his glans, and hot semen gushed out like a cannonball, shooting onto his sister's breasts once, twice, three times, and then spreading all over her flat abdomen. Just then, he felt a warm liquid well up in his sister's eyes, wetting his entire palm. Alan also reached her climax.

After a while, Acheng recovered. "Sister, that felt so good, thank you, dear sister!" Acheng whispered to his sister.

"Brother, I felt so good too... A few days ago, when I touched myself there, I kept thinking, what would it feel like if you were touching me? Maybe it would feel even better!... Now I know, it's much better than I imagined..." Both of them were exhausted and fell asleep in each other's arms.

Late at night, their parents came home to find the siblings fast asleep, completely unaware. Fortunately, their parents didn't go upstairs to check.

The next night, Acheng went upstairs and went straight to his sister's bedroom, took off his underwear (he usually didn't wear a shirt to sleep in the summer heat), and lay down next to his naked sister. The older sister was waiting for him. They began to kiss and caress each other's bodies...

The younger brother's fingertips, dipped in the nectar secreted from his sister's eyes, gently stroked and swirled around her small entrance... The older sister let out a pleasurable moan...

Two minutes later, Alan whispered, "Put it in a little more."

He carefully squeezed his fingertips into his sister's tender opening, his fingertips immediately enveloped by the soft, moist flesh. Alan let out a soft cry: "Ah!... Brother... Just leave it there and don't move... Ah..."
In no time, Acheng felt warm, moist love juice flowing from his sister's vagina, the soft, wet flesh enveloping his fingertips, rhythmically opening and closing. He felt incredibly sexy, and his penis, which his sister was holding and stroking, immediately ejaculated.

The following night, as he carefully inserted his fingertip into her tight, slippery anus and rubbed it around, his sister arched her hips, her urine swallowing the first joint of his finger. She groaned, seemingly complaining, "Use two fingers!... Thicker... I want to feel it... It might be about the same size as your penis..."

Ah Cheng joined his middle and index fingers together and carefully inserted them into his sister's anus. It was too tight; he could only manage to insert about two centimeters of the tip of his finger. She began to tremble, uncontrollably thrusting her vulva, wanting more to be swallowed.

"Ah... So good!" his sister said. Her flesh clamped tightly on her brother's joined fingers. She kept twisting her hips and matching the rhythm of her twisting. She held her brother's cock tightly in her hands and moved it up and down. She gasped and asked, "Brother, does it look like I'm fucking your dick?"

"Sister... I don't know. I've never been fucked before... Oh, sister, you do it like this. It feels so good to me." After
a while, both siblings reached climax.

She picked up the hand he was inserting, put her index and middle fingers together, looked at them carefully, and said: "Brother, they are still not as thick as your cock. I really... really want... to insert your cock into mine and try it. I don't know what it will taste like... It's a pity that you are my biological brother, we can't do that..."

July 2000.

The siblings continued their sexual caress before going to bed. Every night, the younger brother would climb into his older sister's bed and gently kiss her soft, warm lips. The siblings would caress each other until they both reached orgasm.

Curiosity led them to a new experiment. This night, they lay facing each other on their sides. The older sister's hand tightly gripped her brother's hot, hard penis, and she actively pulled him closer. Their eyes met, silent, but both tacitly agreed to the next step.

She shifted her hips, and he adjusted his position accordingly. His erect penis was now at the gates, positioned between her thighs. She grasped his thick shaft, carefully rubbing the glans against the inside and outside of her wet labia. The direct contact of their genitals brought them both unprecedented pleasure…

Acheng felt his penis throbbing, almost about to ejaculate. His sister noticed too; she quickly lay on her back, spread her legs, and pulled her brother onto her, his glans pressing against her eye. Both felt a jolt, and simultaneously let out pleasurable moans.

"Ah…brother, so beautiful, so wonderful!" the sister gasped.

"Sister, I love you, you're unbelievably beautiful!" the brother murmured.

He began to thrust inward, half of his large glans already inside his sister's eye. Alan, alert, quickly shifted his hips, and his glans slipped out of her vaginal opening. His hard penis stood erect, and his sister pressed his buttocks down with her hands, thrusting her genitals forward. Her labia gripped the shaft, and the lower edge of his penis rubbed back and forth like a saw in the honey-scented crevice. They both felt incredibly good.

She whispered in his ear, "I also want you to go inside me... but you know we can't do that, we're siblings... isn't this also very comfortable?"

"Yes, sister..." Acheng always agreed with his sister's opinion, "but I really wish we weren't siblings... sister, I miss your tenderness so much..." The younger brother lay on top of his sister, pressing her breasts into two fleshy mounds.

She breathed heavily, her hips thrusting up and down, feeling the pleasure of his thick, hard penis rubbing against her labia and touching the small bud inside her cleft…

“Sis, I’m going to cum!”

She released her hands from his buttocks, and he lifted his upper body, his penis like a small cannon hidden between their legs, firing in rapid succession, ejaculating onto his sister’s breasts and lower abdomen, with a few drops landing on her face.

Every night in the attic during midsummer was filled with a strong sense of spring.

Although the siblings didn’t actually have intercourse, they had discovered many ways of making love beyond penetration: caressing, licking, oral sex, rubbing his penis against her vulva and outside her mouth… all of which brought them pleasure and satisfaction. They had repeatedly confided in each other how much they longed for real, physical intimacy, but they both knew it was a grave taboo, an incestuous crime of "sibling adultery" forbidden by law. They tried their best to restrain themselves and were extremely careful to keep it a secret, behaving normally in front of others during the day. Before

each sexual encounter with his sister, Ah-Cheng would place a large, dark-colored towel under her buttocks, washing it the next morning and hanging it to dry in their shared bathroom. This way, their parents never discovered any trace of their sexual activity.

The Creator created life. To ensure the continuation and perpetuation of life, the Creator has ingeniously arranged within the genes of every living being the intense desire for intercourse with the opposite sex. No man-made taboos can hinder this overwhelming natural force for the continuation of life.

That night, Ah-Cheng held his erect penis, the glistening purple glans gently rubbing up and down between his sister's smooth labia. "Sister, if you could insert it… just a little bit, I wonder how wonderful that would feel?!" the younger brother whispered.

"I've been thinking that too, it must be wonderful… but we can't do that, we're siblings… and I'm afraid of getting pregnant," the older sister replied softly.

"Can we try just once, just once? Just a little bit in, then pull it out right away. That way you definitely won't get pregnant."

"Shh...don't be loud...you're rubbing me so well..." The older sister moved her vulva, cooperating with her brother's rubbing: "As soon as you said you were going to put it in, I felt it coming..." He also felt very sexy, his penis rubbing back and forth in her vaginal opening faster, and soon both of them reached orgasm.
This was the last three days of July.

July 29th, Saturday.

In the afternoon, their parents had business to attend to in Taipei and wouldn't be back until Sunday afternoon.

That evening, the siblings went upstairs early. As soon as the older sister got into bed, Ah Cheng couldn't wait to pull down her small thong and wantonly grope her vulva. A few days ago was my sister's period. During her period, Alan was a little uncomfortable and wouldn't let Acheng touch her. Today, her period was finally over.

Acheng hadn't ejaculated for three days, and his genitals were still erect and very uncomfortable. Today, he seemed very eager. My sister was also in a good mood today, probably because her period was over and her parents weren't home, so she felt safe and bold enough to play with her brother.

She took off her bra, pushed her brother onto her bed so he was lying on his back, took off his underwear, lay on top of him, and pressed his hard penis into her cleft, twisting her hips to make his penis rub back and forth between her labia. She kissed him passionately, putting her tongue into his mouth and letting him suck on it.

She stopped kissing him and looked at her brother: "I've been wondering what it would feel like to go inside. Maybe we can try it today, just a little bit inside."

Ah Cheng was more than happy to oblige. The sister straddled her brother's lap, holding his erect penis, smearing the glans with nectar from her vulva, and inserted it into the small entrance. She aligned the angle and gently sat down, squeezing most of the glans into the wet opening.

"Ah!" she cried softly, "I can feel it going in!"

She rubbed her hips, moving up and down slightly, until the glans was fully inside, and both of them felt an intoxicating pleasure.

"Brother, it feels so good!"

"Sister, it's amazing!"

Her snow-white, round buttocks continued to rotate and press down. The tip of his penis, about five centimeters long, entered her vagina, but the glans encountered resistance and couldn't go any further. The sister stopped pressing down and began to rhythmically contract her vaginal walls, squeezing the penis that her brother had inserted. An inexplicable pleasure suddenly surged into Acheng's mind. He knew he was about to ejaculate, so he quickly pulled out his penis, and like a pump, his semen shot onto his sister's breasts and lower abdomen.

"That was amazing!" She rubbed her labia against her brother's still-erect penis after ejaculation. "Thank you, big-dicked brother! Now I know what it feels like to have a penis inside! It's so much better than rubbing against a stick outside! Right? But we'd better not do it again, it's too dangerous!"

"Yes, I almost ejaculated inside you." Ah-Cheng agreed with his sister.

The next evening, their parents came home. For the next few nights, the siblings returned to their previous "non-intercourse" sex routine.

August 2000.

August 5th, another Saturday.

That night, the sister lay on top of her brother, swaying her plump, white buttocks, her wet labia slowly and rhythmically grinding against Ah-Cheng's hard, erect penis. Slightly breathless, the older sister whispered in her younger brother's ear, "Brother, last time you only went in a little bit, it felt so good. Shall we do it again?"

Ah-Cheng excitedly agreed, "Of course! Sis, I'll be extra careful!" He grasped his erect penis, aligning it with his sister's vulva. She half-sat, half-squatted, positioning the glans against the entrance of her vagina. Adjusting the angle, she slowly lowered her hips, her small opening swallowing the entire glans.

"Ah! Even better than last time," she whispered to her brother.

Her vagina gripped his glans tightly, and after a few seconds, she began to rub her vulva. Ah-Cheng sensed his sister's increasing arousal, and her vulva becoming increasingly slippery. Alan murmured, "Last time it only went in a little bit... I think... this time I'll let it all the way in and see what it feels like."

"That's for the best! I'll tell you before I ejaculate, and then I'll pull it out immediately!" the younger brother said excitedly.

She slowly lowered her hips, his penis penetrating deeper and deeper. "Let's take it slow. Some experienced classmates told me that the first time is a little painful," the older sister said.

"Sis, don't rush, I don't want to hurt you!" the younger brother said worriedly.

He looked at his sister's swollen, red labia, translucent milky fluid seeping from between her labia, flowing down the rim of his penis; their pubic hair was already soaked.

He felt resistance at the head of his penis—it was his sister's hymen!

"Okay! Brother, lift up!" the older sister said, pressing her buttocks down at the same time.

The younger brother erected his penis, feeling the glans break through the barrier of his sister's vagina. He continued pushing, and in an instant, his entire penis was inside her!

"It doesn't hurt much; in fact, I feel great," the sister said.

Ah Cheng felt an indescribable pleasure, but he didn't forget his promise to his sister: "Sis, take it out quickly, I'm going to cum!"

She quickly raised her vulva, and as soon as his penis slipped out of the beautiful crevice that tightly enveloped it, it shot out thick, cloudy white semen like a pump. The shaft was covered in the oily liquid, with a few streaks of bright red blood.

"We finally did it, really!" "

Hmm, sis, I don't think this counts as real sex... My classmate said that sex is about the penis being inside and thrusting in and out at various angles. Real sex involves thrusting for a while, then the penis ejaculates inside, and both partners reach orgasm. It's not just about staying inside or pulling out and ejaculating outside... You know what I mean?"

The older sister said thoughtfully, "Yes, you're right, I understand. But that kind of sex is something siblings shouldn't do. We were just experimenting with the feeling of the penis inside, that's different from real sex, what we did doesn't count as sex..." Then she chuckled softly, "Brother, you've already taken my virginity, what do you say now?!"

"Sister, I love you! It's so wonderful, but the little bee hasn't had enough yet."

For the next few nights, they returned to their previous caressing and kissing ways. If his sister didn't ask for penetration, Ah Cheng would never force her; he would never do anything she didn't want to do. In fact, Ah Cheng knew he was incredibly lucky. Every night he could play with and lick his beautiful sister's soft, white breasts and plump vulva, caress her entire body, and rub his penis against her lovely genitals…

She even let him actually "penetrate" her once, her virginity… He believed none of his classmates were as fortunate as him.

August 9th, Wednesday.

Night fell. In the attic, Ah Cheng lay on his sister Ah Lan's soft, naked body, gently kissing her. He had now learned to avoid hurting his beloved sister. He supported most of his weight with his elbows and knees, his chest gently pressing against her breasts. Their lower abdomens were pressed together, and his engorged, hard penis rubbed back and forth in her wet, fleshy cleft. It repeatedly touched the budding flower bud peeking out from the crevice, and she let out a plaintive moan.

"Sister, you're so beautiful! I love you so much, sister!" the younger brother praised sincerely.

"Brother, you're so handsome!... My big cock, my good brother, I love you so much!" She thrust her vulva forward, moving in sync with her brother's hips, her delicate hands stroking his head and back: "Brother, I'm about to come. Can you do what you did last time and put your whole cock in? This time, stay inside a little longer so I can feel the sensation of your cock inside me."

He didn't say a word and immediately and gently complied. The sister spread her beautiful legs, raised her knees, and the head of her brother's cock aligned with her vaginal opening, thrusting his hips.

Ten seconds later, the fifteen-centimeter-long penis (yes! It had grown another centimeter since summer vacation!) was fully inserted into the sister's tight little hole. He felt the soft, wet walls trembling. He let it stay inside, motionless, and that feeling was wonderful!

"Brother, can we go in and out twice?... If we go in twice and then stop, that... it probably won't count as real sex." The older sister pleaded anxiously.

"Okay!" The younger brother immediately acted, slowly pulling his penis out completely, then quickly inserting it again, all the way in at once.

"Ah... ah... so good... I'm almost there..." The younger brother slowly pulled out completely again, then slowly inserted it all the way in. "

Ah... I'm coming... there's a big cock in my hole... I'm coming..." she cried out joyfully, her voice growing weaker and weaker, a warm, moist nectar flowing from her flower.

Acheng felt waves of pleasure emanating from the cock inserted in her vagina, but he tried his best to hold back, until the very last moment, when he quickly pulled out and ejaculated. The first two drops shot onto her sister's lips, the rest splashing onto her breasts and lower abdomen. She wiped the semen from her lips with the back of her hand, her breasts heaving, her heart racing, a happy smile on her face.

After a brief pause, she calmly said, "It was so amazing!... We almost... felt like we were really..."

"Sis, it seems to feel better and more comfortable each time. Last time I almost ejaculated inside you immediately, but this time I'm not as flustered or sensitive, and I can control myself better, but we still have to be very careful."

Recently, Ah-Cheng's stamina has improved significantly, and each time his sister reaches orgasm first. He only ejaculates after his sister has orgasmed once or twice.

"I know. We can only dream about it... We're siblings... You absolutely can't ejaculate inside... I'll get pregnant..."
A week later, the weather got hotter, and the siblings' passion intensified. Alan grew increasingly fond of her younger brother, Cheng. Her handsome and strong brother was gentle, dashing, and always so obedient to his sister.

She had already climaxed once, and she lay on top of him, her love-drenched lips gently rubbing his still-hard penis up and down.

She sat up, smiling at her brother. He held her white, tender buttocks, his penis erect like a rocket ready to launch, glistening with the slippery nectar from her previous climax. She moved her vulva, letting the glans rub against her labia, touching the small bud within.

The cleft was filled with a trickling fluid. This time, her vulva was raised slightly higher, and the purplish glans unexpectedly slid to the slightly sunken opening beneath the labia, the glans perfectly pressing against the small entrance. As soon as she sat down, the hard penis smoothly slid into her tight, slippery vagina.

Alan let out an "Oh," feeling both swollen and blissful. She gazed at her handsome brother, leaned down to give him a wet kiss, and twisted her hips. He immediately thrust his hips forward, allowing his penis to penetrate deeper. After a few thrusts, his penis was fully inserted, the glans pressing tightly against the soft flesh deep within his sister's clitoris.

She interrupted the kiss and whispered in her brother's ear, "I want to cum again. You can thrust like last time, but this time you can thrust more. Let's try what it really feels like to make love."

"Okay, sis, I'll stay longer this time and do it more times!"

"As long as you don't ejaculate inside me, it's okay to do it more times!"

Ah Cheng simply couldn't believe that his sexy and beautiful sister was actually going to make love to him, instead of just inserting without moving like the last two times, or having to pull out after two thrusts.

His sister's buttocks, which were on top of him, had begun to sway and wriggle, and he also began to slowly move his buttocks, coordinating with his sister's movements. His penis began to make a half-in, half-out piston motion in her tight, warm, and slippery little hole.

"Ah...ah...brother...so beautiful...I've never felt so good before..." the sister gasped. "It's amazing...ah...oh..."

From her expression and moans, Ah Cheng knew she was truly enjoying herself. She straddled him like a horse, and he reached out and pressed his hands against her firm, white buttocks, helping them rise and fall in sync with his erect penis. He felt her vagina was very tight, but thankfully it was very lubricated, which didn't hinder his thrusting.

Both of them closed their eyes, enjoying the wonderful sensation of each thrust... They gradually increased the depth of their movements and quickened the pace...

He opened his eyes to look at his sister; she had her eyes closed, her head slightly tilted back, her mouth slightly open, her pair of white breasts swaying up and down, and she was constantly emitting low moans of "ah...oh..."

After a while, suddenly...

"Ah ...

She lay limply on top of him, passionately kissing him. He took her delicate tongue in his mouth, and she let him suckle.

After a while, she said, "If you had ejaculated inside me just now, then we would have truly made love. I wonder how wonderful that would have felt? I really wish we could try it once… but that's too dangerous… absolutely not…" With that, she quickly fell into a deep sleep.

Ah Cheng had never ejaculated so comfortably before. The pleasure was incomparable to masturbation, or his sister stroking him, or even the feeling of ejaculating through friction on her vulva. The feeling of ejaculating after his penis had thrust deeply into his sister's flesh was so liberating and satisfying, completely different from the emptiness and loss he felt after masturbation.

He was tired too, so he embraced his sister and fell asleep. He completely forgot that his parents downstairs might come up to check and find the siblings naked and embracing in the same bed. Fortunately, his parents didn't come up to check.

The next day, both siblings felt a deep sense of guilt, realizing that they had "really" violated the taboo of incest. But driven by hormones, at night, they were once again locked in a passionate, naked embrace. There was no "penetration" or intercourse; just like before, they kissed, caressed, and rubbed... until they both reached climax, then fell asleep in each other's arms.

August 19th, Saturday.

That night, Ah Cheng lay gently on his sister's naked body, the two sharing a passionate kiss, their tongues locked in each other's. His sister pushed him off, straddling him, and once again held his thick, hard penis tightly between her wet labia, her eyes misty as she smiled at him.

"I've been thinking about how we made love a few days ago," she said softly. "It was so wonderful, so pleasurable. Why is something so beautiful called 'incest,' something we can't do? I keep thinking about making love with you like that again, about playing hard and pleasurable many times!" As she spoke, she grasped his erect penis with her delicate hand, guiding the glans into her vagina.

"Sister, I've also been wanting to make love with you to the fullest!" her brother replied excitedly.

The meat tightly held the ping-pong ball-sized glans, and her small tongue licked her brother's lips. He gently raised his hips, and the first half of his cock slid in and out of the juicy vagina. She bucked and twisted to match his thrusts... After a while, the small flesh hole swallowed up the entire fifteen centimeter long thick cock. He felt that her flesh hole was hot, tight and soft, the glans head pressed against a ball of tender meat, and his ball sac pressed against the curve of his sister's ass.

They paused for a moment to let the little one get used to the bulge inserted by the thick cock. Her vaginal walls involuntarily tightened and relaxed, tightened and relaxed... He felt his penis being squeezed by a tight, hot bag, and his shaft became harder and swollen accordingly...

After a while, the older sister got used to the penis invading her flower core, and she leaned down to kiss his mouth and cheek. She raised her jade buttocks, letting the penis slowly withdraw. "Pop!" The glans slipped out of the tightly gripping vaginal opening, making a crisp sound.

The younger brother's hard penis brought the older sister an indescribable pleasure, and she immediately grabbed the big rod, stuffed it back into her tender vaginal opening, and thrust her hips to let it go all the way in.

They repeated this several times, and then quickened the rhythm of their thrusting. He no longer allowed his penis to completely separate from her vagina, keeping the glans inside each time he withdrew before inserting it fully again…

Both were immersed in the pleasure of their genitals rubbing together. He thrust his erect penis in and out of his sister's tight, warm, and moist vagina again and again… Her legs were tightly wrapped around her brother's waist and hips, she leaned down, her breasts pressed against his chest, her arms tightly embracing him, her buttocks moving up and down rapidly.

They made love wildly and passionately. At this moment, in their senses, everything else in the world ceased to exist; only they, the brother and sister, were immersed in wonderful carnal desire, intimately united as one.

"I'm about to come!" the sister gasped.

The younger brother intensified his thrusts, his glans plunging deep inside, slamming against the soft flesh of her clitoris.

"Oh...oh...ah...it's so sore..." the older sister cried out, a large gush of warm, moist fluid gushing from her clitoris, making her already wet vaginal canal even more slippery.

Hearing his sister's cry of "sour," Ah Cheng's glans also felt a strange tingling and itching sensation. He knew he was about to ejaculate. "Sis, I'm going to cum, pull out quickly..." Ah Cheng tried to push his sister off him and pull his penis out.

The older sister opened her beautiful eyes, gazed at Ah Cheng, and excitedly said, "Shoot inside! Shoot inside my sister!"
Her jade arms tightly embraced him, her thighs clamped around his waist, and she thrust her vulva forward, locking the man's penis deeply inserted into her vagina. Her delicate tongue darted into her brother's mouth, eagerly urging him to suckle.

He eagerly took his sister's tongue into his mouth, greedily sucking, his penis swelling even thicker and longer, feeling it swell to an unprecedented length and hardness. Under his sister's thrusting, he felt his engorged glans squeeze into the crevice of her soft flesh, breaking through the bottleneck of the soft flesh.

"Oh...yo...yoyoyo..." the older sister cried out in ecstasy. Ah Cheng quickly sealed her cherry-like mouth with his lips, suppressing her cries to the lowest possible level.

His glans felt an intense tingling sensation, and he couldn't hold back any longer. His urethral opening throbbed once, twice, three times, four times, five times... and hot semen gushed out, spraying all over his sister's uterus.

A while after ejaculating, his penis returned to its original size, softening slightly, but still semi-erect. The siblings remained tightly embracing each other, both covered in sweat. She smiled lovingly at him, and they shared a sweet, wet kiss. Her buttocks continued to slowly rub and sway, her vaginal walls opening and closing, as if trying to suck up the last drop of semen from her brother's penis.

After a long while, the siblings drifted into a sweet dream. She remained lying on top of him, his genitals softened and slipped out of her vagina, the still-thick shaft lying between her slippery labia, the glans pressed against her moist, sparse pubic hair.

The next morning at eight o'clock, their mother called from downstairs, "Alan, Cheng, why aren't you up yet? Breakfast is getting cold!"

The siblings awoke from their deep sleep. Their eyes met, both feeling conflicted: they had experienced unprecedented satisfaction the previous night, but deep down they were also filled with a sense of guilt. Cheng felt guilty for having ejaculated "really" deep inside his sister's vagina and dared not look her in the eye; Alan also felt an indescribable unease.

"Let's talk tonight. Maybe we shouldn't be doing this, we can't continue like this..." Alan said with some remorse.
Three days ago, his sister started her period, and Acheng hadn't had sex for three days. Today, his sister was "clean," so he took off his own clothes and removed his sister's underwear, starting to fondle her breasts and vulva.

The first volume of the comic tells the story of three high school girls and their boyfriends going to a lakeside, only to be seen by three escaped convicts hiding in the woods by the lake. With no one else around, the three men threatened the three boys with knives, tied them to trees in the woods, and ordered the girls to take off their underwear and trousers, lewdly fondling their breasts and vulvas. First, they forced the girls to perform oral sex and suck their penises. Then, each man grabbed a girl and raped her vagina in front of their boyfriends, venting his lust. Then they switched partners, gang-raping the three innocent female students in various positions. Each of them was gang-raped four or five times, and also sodomized once, their genitals a mess, their vulvas swollen and bruised… The illustrations were very realistic and vivid, especially the exaggerated close-ups of the large penises forcibly penetrating the vaginas, which were incredibly lifelike and arousing.

Before she had even finished reading the first volume, the older sister threw down the book, her voice hoarse, and said urgently, “Brother, come and rape your sister! Like the men raping girls in these comics…”

Acheng imitated every pose from the comics, passionately ravaging his sister's tender flesh...

After two hours of "simulated rape" by his younger brother, Acheng ejaculated into his sister's vagina four times. His sister's body went limp, her beautiful eyes closed, and she fell peacefully asleep.

After resting for a while, Acheng put on his clothes and hurried to Xiao Xu's house to return the books.

As soon as Acheng left home, his mother returned. After shopping this afternoon, she didn't go back to the store but went straight home, three hours earlier than usual. Holding the 34C bra she had just bought for Alan, she went upstairs to put it on her daughter's bed.

The scene before her eyes shocked her. The daughter lay naked on her back on the bed, legs spread wide, a large towel placed under her buttocks, covered in a mess of fluids. Thick, sticky fluid clung to her vulva and between her thighs, and a semi-transparent, cloudy discharge continued to seep from her opening.

"Ah! Alan was home alone and was raped by a bad man!" The mother came to her daughter's side, gently shaking her head: "Alan, wake up... what happened?"

Alan's reaction shocked her even more. In her drowsy state, Alan didn't hear her mother's voice clearly, thinking it was her younger brother returning: "Brother, you were really good today, you're getting better and better... I was almost raped to death by you..."

The mother, Jian Yi, couldn't believe her ears. Was it Acheng who did it? Judging from their tone, they had probably done it many times already; no wonder there were so many traces of semen and vaginal fluid on the sheets a few days ago.

"Alan, get up!"

Opening her beautiful eyes, Alan finally recognized her mother. She was both ashamed and anxious, and covered her face, crying.

"Get up, put on your clothes, and tell your mother what happened," her mother said, both angry and concerned.

Alan sobbed as she told her mother about her relationship with Acheng, repeatedly emphasizing that it was her fault, not her brother Acheng's. He hadn't forced himself on her; she had fallen in love with him involuntarily and had sex with him.

After some calm reflection, the mother hugged her beloved daughter and said, "Alan, since you've already done it, there's no use in regretting it. The most important thing is that your brother can't get you pregnant; that would be truly hopeless. And we can't let Dad find out either. If he gets angry and makes a scene, our happy little family will be finished..."

"Mom, I'm so unfilial for doing something like this with my brother. I'm so sorry... I've tried desperately to stop having sex with my brother, but for some reason, I just can't control myself..."

"Alan, you haven't gotten pregnant yet, and only you, me, and Cheng know about your relationship with your brother. Thankfully, nothing terrible has happened. I just want to ask you, do you want to cut ties completely with Cheng, or will you still be unable to resist, maintaining a lingering connection, stopping today and doing it again tomorrow? I know that during adolescence, sexual desire and emotions are the hardest to control! I've had the same experience."

"Mom, to be honest, I love Cheng so much... I always want to have sex with him... I'm afraid I can't break it off!... Mom, thank you for being so understanding and forgiving... Mom, you said you've had the same experience?!"

"That's a secret, only you and I can know... You can't tell anyone, including Cheng."

"Mom, I promise I won't tell anyone!" Alan said.

"My first time was with your uncle... I was about your age then... Our relationship has continued until now. Maybe you have my genes, like loving to have sex with your brother..."

Alan's mother is 34 years old, fair-skinned and beautiful. She has only one brother and no other siblings.
Alan's uncle is 33 years old, a very handsome man, unmarried, and runs a chain of stores in the north, owning a McDonald's. He visits them every month, or his mother visits him.

"Ah! Mommy! You two are so great!... Tell me your secret love story, okay? Does Daddy know about you and Uncle?" Alan asked excitedly.

"I'll tell you more about my secret sexual relationship with your uncle later. Before our marriage, your father and I each had regular sexual partners, but they were all lovers with whom we couldn't officially marry... When we got married, we made a secret agreement: he could continue to have that lover who couldn't marry him, but who would never interfere with our marriage or relationship, and so could I. But we also agreed that no one else would be allowed to get involved." "

Who is Dad's secret lover?" Alan asked curiously.

"I can't say, it's a promise your father and I made." Mom changed the subject: "If you want to continue being with Acheng, you must keep it a secret, be careful, and absolutely cannot get pregnant now. You're still a high school student, that would ruin your future. Has Acheng been using condoms? I'll buy you birth control pills starting tomorrow, take them on time... You like Acheng so much, is he good in bed? Does he want a lot?" Mom asked.

Alan was deeply grateful for her mother's support and love, and of course she could be open and honest with her mother.

"Ah Cheng said he doesn't want to wear a condom, because it would reduce the feeling of real penetration and friction... He's very strong, he wants a lot, and he's getting stronger and stronger. At first, he ejaculated before me, but now he only ejaculates once after I've ejaculated several times. Each time he goes at it for a long time, and I'm almost dying from his penetration... yet there's an indescribable pleasure..."

"Hmm, 'like uncle, like nephew,' that's absolutely true!" Mom looked at her daughter, revealing a mysterious and knowing smile.

Alan was almost certain that her father's secret mistress must be her beautiful and sexy aunt, her father's only sister, who was three years younger than him.

That night, Ah Cheng's penis was deeply inserted into his sister's tender flower, and his sister twisted her jade buttocks, letting out a sick moan from her throat. The younger brother held his sister's two plump and pointed breasts, taking turns tasting them. Alan didn't tell her younger brother about her conversation with their mother that afternoon; it was a secret agreement between them. However, she did tell him that for safety, she would be taking her birth control pills regularly.

School started, and both siblings were busy with homework every day. They managed to sneak in some time for a romantic encounter an average of twice a week.

The semester ended, and the older sister remained at the top of her class as usual. Unexpectedly, Acheng's grades improved significantly, rising from ninth or tenth place to second. The teachers all said he was "single-minded," never fooling around with girls, and was a model student in the school, excelling in character, academics, and physical education.

The father was very satisfied with his son and daughter's academic performance. He also noticed that his daughter was becoming increasingly beautiful, especially her breasts, which were full, firm, and particularly eye-catching.

"My daughter really looks like a grown-up now, just like her mother. Hmm...and a bit like my little sister too..." the father thought to himself.

He thought that now that his daughter was older, perhaps he should give her a larger, more proper "bedroom." He considered renovating his downstairs "office" to serve as his daughter's boudoir.

He made this suggestion at the dinner table. Surprisingly, his daughter said that her current bedroom was perfectly fine and there was no need to move downstairs.

Mother said, "Alan lives upstairs, and she's always been doing fine. I think it's okay as usual!" Then, out of Father's sight, she winked and smiled at her daughter.

February 2001.

Although it was still chilly outside, spring was in full bloom in the attic. The older sister's long, white legs were spread apart, her knees bent and raised high; the younger brother stood before her bed, his upper body pressing against her pert breasts, his 16-centimeter-long, thick penis, its veins bulging, rhythmically thrusting in and out of her tight, wet vagina. Their pubic hair was soaked, and the pink, tender flesh of their vaginal openings rolled in and out with each thrust of the hard penis. Between the sister's fair thighs was a pool of slippery fluid… The sister's slender arms embraced her brother, her small hands stroking his back, her beautiful eyes closed, enjoying the powerful force of his thrusts and the tender kisses above.

The attic echoed with the sister's plaintive moans, the brother's heavy breathing, and the squelching sounds of their genitals rubbing together.
