Passionate sisters

After my relationship with my sister began, I gradually got used to it. Whenever I needed something, my sister would try her best to satisfy me, even though it was a bit frequent for a 21-year-old like me. But young people's passion is boundless; and my mature 23-year-old sister wasn't someone who could be easily satisfied.

Of course, my relationship with my sister had to be kept secret, because we also had to be wary of our younger sister, Debbie.

My sister was not yet nineteen, but she was precocious, with a curvaceous figure, especially her hips, which, although small, were pointed and perky, very alluring. However, initially, I didn't realize the changes in my sister's body; in my mind, she would always be a young girl who never grew up.

Somehow, my sister seemed to sense that my sister and I were hiding something from her. Fortunately, she hadn't really discovered anything yet. Although she was still young and couldn't control us, it would be bad if she found out.

My sister and I would make love wildly whenever we had the chance—in the kitchen, in the bedroom, in the bathroom, and even in the swimming pool—there are evidence of our lovemaking. Of course, all of this could only happen when my sister wasn't home. I enjoyed the feeling of sneaking around, because it was more exciting than openly displaying my lust.

To me, my sister was still just a spoiled, nosy little kid who often ruined my and my sister's trysts.

Anyway, I never really cared about her. It wasn't until she was nineteen and went to university in the same city as me that we had more time to see each other. But there were a lot of guys at school who seemed very interested in my sister. They were always hanging around her, guessing her real age and her various hobbies.

Whenever these guys bothered my sister, I would angrily step in and chase them all away without hesitation. It wasn't that I liked protecting my sister, but I felt they had no taste, being so shameless as to make a move on a mere immature girl.

I'm not trying to be evasive; in fact, in my eyes, my sister really was a spoiled brat. At home, she relied on my sister and me for everything; without us, she knew almost nothing and couldn't do anything.

However, she was indeed jealous of the close relationship between my sister and me. For someone as oblivious as me, failing to grasp the underlying meaning sooner was my mistake.

Two months passed like this. Sometimes, strange noises would come from my sister's room, but I paid no attention.

One night, I woke up in the middle of the night, feeling a bit hungry. Because my sister had been following me around like a shadow these past few days, I hadn't had much of a chance to make love with my sister, so I often woke up in the middle of the night, experiencing the emptiness and loneliness of the night. I decided to go to the kitchen to find something to eat. I thought it was so late, everyone else should be asleep, so I didn't put on any clothes and went downstairs naked.

Our house has two floors; my sister's and my bedroom were upstairs, and my sister's bedroom was downstairs, very close to the bathroom.

In the darkness, I groped my way down the stairs to the refrigerator; my sister's room was next to the kitchen.

As I passed through the hallway, I noticed that my sister's door was ajar, letting in a sliver of light.

Out of curiosity, I stopped and peeked inside.

Oh! I couldn't believe my eyes!

My sister was standing naked in front of the mirror, but she felt so unfamiliar to me. The naive, immature girl of the past was gone, replaced by a budding young woman.

Two buds had appeared on her chest, their curves quite beautiful, whereas two years ago, there had been nothing there. Her buttocks were clearly developing, their graceful curves already outlined, her hips wide; a little more flesh and she would be indistinguishable from a mature woman.

Although she still looked very thin, and was indeed still a child, there was a clear difference compared to before. In other words, she had begun to mature. Her thighs were no longer as thin as matchsticks, but rather quite rounded and full. Her back looked very supple, her spine straight, no longer the unsightly bulge of her childhood. I never imagined my sister had developed to this extent so quickly, completely different from the skinny girl I remembered. My sister

stood in front of the mirror, gazing intently at her reflection, completely unaware that another pair of eyes were watching her from within the mirror. Through the mirror, I could see my sister's entire face, from head to toe. Where there used to be only her belly button, now the area is flat with a slight curve. Her once flat, board-like breasts are now two sizable mounds, each adorned with two truly adorable little red hickeys.

What shocked me most was my sister's once hairless inner thighs, now covered in fine, curly, pale yellow pubic hair, with a cute little slit running through them.

Oh! How cute!

In just a short while, my opinion of my sister underwent a complete 180-degree turn. The sister standing before me was now a young woman, a lovely, vibrant girl in the throes of puberty, no longer the skinny, unpleasant girl of the past.

She was tall, quite beautiful, with a sexy mouth like her sister, and a pair of bright, clear brown eyes inherited from their father. All of this was already enough to leave me speechless, but what she began to do truly gave me a powerful shock.

My sister stood in front of the mirror, striking various poses, turning her body from side to side, seemingly admiring her young, naked body with a touch of self-pity. Then, mimicking a model in a photograph, she closed her eyes, her hands roaming over her chest, caressing her small, cute breasts. Her slender fingers pinched her nipples, gently rubbing them, her expression one of ecstasy. She bit her lower lip, emitting low moans. The scene resembled a porn star's desperate masturbation performance on television.

Standing outside my sister's door, watching this vivid and sensual spectacle, I was dumbfounded, unable to move an inch. I had never seen anything like it before, and now I was completely captivated, my penis unconsciously hardening.

My sister continued to caress her breasts until her nipples were fully erect. Her nipples weren't very large, and I couldn't see them clearly from this distance, but I could easily discern that her two originally red nipples had turned black.

Her hands slowly moved down, beginning to caress her entire body. Her hand slid over her flat stomach, down to her rounded buttocks, gently kneading and squeezing her hips. She lifted her right leg, her hand starting from her ankle, sliding up her firm calf, past her knee, down her thigh, and step by step towards her groin.

My sister's breathing quickened, and I panted along with her. I stared intently at my sister's young and beautiful body, somewhat unable to believe that she was so well-developed at such a young age.

As if rewarding herself, my sister sighed and slid her hand between her legs. Through the mirror, I could clearly see her middle finger inserted into the small cleft at the base of her thigh, gently and rhythmically moving back and forth. However, each time her middle finger only penetrated shallowly into the cleft by one knuckle before stopping, not going deep or stirring inside, but it seemed that this was already enough to satisfy her.

Of course I knew what she was doing, but I never expected that watching my sister masturbate would excite me so much. I watched with envy as her slender fingers moved freely in and out of that cute little hole, wishing my already painfully hard penis could take its place. I was thrilled by this lewd thought.

Oh, my little sister is satisfying herself with her fingers, and her brother is hiding and watching!

My sister released her breast with her left hand, pressed it against the wall, supported her body, spread her legs, bent her knees, and slowly slid her right middle finger into the crevice until her entire finger was buried inside.

I, who had been secretly watching, could no longer resist. I grabbed my penis and began to vigorously rub it in sync with my sister's movements, fantasizing that it wouldn't be my sister's fingers entering her narrow, pink hole, but my thick, long penis.

Under my gaze, my sister knelt down, her knees on the ground, supporting her body, her thighs spread, her fingers rapidly moving in and out of her little hole, looking completely absorbed.

I watched from outside the door, my eyes burning and my heart pounding. My penis was erect, and I pushed the door open a little more, sticking my head in halfway. Thankfully, my sister didn't notice at all.

It was truly a strange scene: my sister was lost in ecstasy, caressing her vulva inside, while her brother outside was watching and vigorously rubbing his penis.

About two minutes later, her thighs began to tremble, obviously because she had been kneeling for too long. I wondered why she didn't lie down on the bed; that would be much more comfortable. As if my sister had a telepathic connection with me, in a flash, she stood up and quickly got onto her bed, her fingers still inserted in her little hole.

As she lay down, her legs were spread wide in my direction—lucky me! This time I could see everything between my sister's legs clearly. Her fingers were still constantly moving in and out of that cute little hole. Under the light, her inner thighs glistened; it seemed she was quite wet.

The speed of her fingers' movements increased, her thighs were completely stiff, spread wide, and her muscles were taut. Her free hand was clenched tightly, her nails digging deep into her palm. It seemed her orgasm was imminent.

Her breathing suddenly became rapid, her thighs and lower abdomen contracted and spasmed violently, and she made a "hoho" sound in her throat. When my sister and I did it together, she behaved just like my sister before her orgasm.

I had never heard my sister make such sexy, suppressed sounds before. She was obviously afraid that the sound would be too loud and attract our attention, so she covered her mouth with the back of her hand, but the "ee-ooh" sounds continued.

Her buttocks were raised high, constantly thrusting upwards, and I could see drops of clear liquid dripping from her little hole.

My sister's body finally fell back onto the bed. Her breathing was still rapid, but her tense muscles had begun to relax. Her hands were casually placed at her sides, and she looked completely exhausted.

From my angle, I could see that her nipples and two lovely labia were red, but covered with mottled, clear fluid. My sister looked very satisfied and happy. As she turned over, intending to further stimulate herself, her head turned, and her eyes glanced casually towards the door.

Suddenly, her eyes widened. I was startled and realized that the door had been half-open, and most of my body was exposed to the light.

I stood there dumbfounded in the doorway, naked, my large, long, and hard penis erect. Due to the previous rubbing, the glans was extremely engorged and glowed red, looking quite terrifying.

My sister immediately shrank to the corner of the bed, her eyes wide open, half shy and half frightened, her lips tightly pursed.

Soon, she showed an expression of disgust.

"Get away!" she hissed, her voice soft but filled with disgust. "Get out of my room, you pervert! Get away!" I didn't say a word, took a step back out of my sister's room, closed the door behind me, and went back to my own room, completely forgetting about going to the kitchen to find something to eat.

Back in my bedroom, I turned off the light and collapsed onto the bed, but I couldn't fall asleep. Every time I closed my eyes, my sister's naked body would appear in my mind, along with the way she had been posing in front of the mirror.

In just over two years, my sister had really changed a lot; she was no longer the naive girl

she used to be. I had seen her naked before, but I had never had any adverse reaction. I never expected that I would have made such a fool of myself just now. Recalling the scene, when my sister discovered that I was peeking, although she seemed very angry, she didn't try to cover herself up. Instead, she spread her legs wide, as if afraid I couldn't see clearly. Moreover, although she seemed angry as she told me to leave, her eyes were fixed on my enormous member, and the look in her eyes was more of surprise than anger.

Thinking about this, I couldn't help but feel excited. It seemed I would definitely let her see my penis properly sometime in the future, and very closely at that.

The next day, everything was normal, as if nothing had happened. As usual, my sister and I went to school after breakfast.

My older sister always got up very early to make breakfast for us, even though it delayed her from going to work.

In my memory, my sister rarely slept in the night before we had school, even if I had exhausted her the night before, she would still get up early to prepare everything.

When I went downstairs to the kitchen, my sister hadn't come out yet. Usually, she was always there before me, but today it seemed I had gotten there first.

"Hai, good morning! You look great," my sister greeted me.

"Hai, good morning! You look even more beautiful, sister," I replied casually, reaching my hand inside my sister's robe and touching between her legs.

My fingers easily found my sister's warm, moist labia. Oh! She wasn't wearing any underwear at all. My penis instantly hardened.

If my sister weren't home, I would have eagerly lifted her robe, pushed her to the sink, and, as usual, pounded into her wet, hot, hairy cunt from behind.

"Mmm...mmm..." My sister moaned as my fingers touched her, rubbing her labia against mine, saying, "Mmm...! Be careful, baby. Your sister will see. Where is she? Hasn't she come yet? She should be down here by now." "Ignore her!" I said, gently stirring my fingers against the walls of her cunt. "Maybe she's drowning in the toilet." "How could you say that about your sister!" My sister was a little angry, pushing my hand away from her cunt.

I deliberately licked my wet middle finger, and my sister smiled, her eyes fixed intently on the bulge in my shorts. She reached out and grabbed my erect penis, about to take the next step, when we heard my younger sister open the door.

"We'll talk about it later, baby," my older sister whispered, pinching my penis hard before letting go.

My younger sister didn't even glance at me, going straight to her seat and sitting down. When my older sister greeted her good morning, she just nodded. I hoped she would look up at me, but she ignored me completely, as if I didn't exist.

"Little brother, what's wrong? Are you feeling unwell?" My older sister clearly noticed my younger sister's unusual behavior.

My younger sister just shook her head and glared at me fiercely.

My older sister sensed something was wrong between us, but obviously thought it was just a normal sibling squabble and ignored it, going to prepare breakfast.

I stared blankly at my older sister's full hips swaying inside her robe, cursing my younger sister inwardly. Why did she have to come in at the worst possible time, just when we were about to get down to business? However, in a flash, I remembered my sister's passionate performance last night, and I couldn't help but look at her in a new light.

Hmm, it seems my sister is a bit lewd just like her older sister.

If I play the right card next, maybe I'll get some unexpected gains, and it certainly won't be as simple as just seeing my sister's cute little hole.

Just looking at my older sister's butt was already enough to excite me, but now, thinking about my sister's lewd performance last night and my aspirations for the future, my penis became even harder.

To hide my embarrassment, I lowered my head and pretended to eat, but my mind was still racing with wild thoughts.

My younger sister sat next to me, less than a few meters away; I could touch her knee with my outstretched leg. Thinking about how naked she had been last night, my feet began to twitch. I continued to wonder what it would look like under her legs if I looked down at the table. Would she be without underwear, her pubic hair still showing?

I wondered if I should pretend to drop my napkin and sneak a peek while bending down to pick it up. But I quickly dismissed the idea, because I never use napkins; I usually wipe my hands with my shorts. People would find it strange if I suddenly started using one.

I looked up at my older sister; she was facing the wall. I thought this was a good opportunity.

My sister had been watching me closely, and seeing me looking at my sister's backside again, she kicked me under the table, a little annoyed. I turned back and gave her a strange smile, continuing to eat my breakfast, but my mind was still contemplating how to get under the table and peek between her legs.

Oh, it seems a lot can happen in two years; at least your sister can change to an unimaginable degree.

Before, I only saw her as a repulsive, annoying person I wanted to avoid at all costs. Now, I genuinely wanted her, I wanted to possess her. Although she was still very young, she had a youthful and beautiful body, and she was maturing rapidly. The day I could "pluck" her wouldn't be far off!

I ate my food absentmindedly, but my mind was replaying the image of my sister's legs spread wide last night. Her labia were truly pink, looking very delicate, and the pubic hair on both sides hadn't fully grown yet, but it made her look even cuter.

I imagined what color her underwear would be if she wore it, and what kind of clothes she was wearing today.

Thinking this, I glanced up at my sister and found that she was also staring at me. Oh, the way she looked at me was exactly the same as the way I looked at her! My penis unconsciously became erect, and my thoughts somehow drifted to my sister's cute pink little hole.

We stared at each other for a while before I regained my usual disdainful expression when I looked at her. At the same time, I saw my sister's mouth move, and I realized that she was asking me a question.

"Hmm? What?" I asked.

"I'm asking you, what's going on between you two? You both look so upset, are you worried the sky is falling? I see you're busy putting seasonings into your porridge, but you're not eating any. And what about the milk I made? It's not very good, why aren't you touching it? What's wrong with you two?" I grumbled a few times, quickly finishing the ham and egg my sister shoved into my mouth. My sister also didn't say a word, just kept her head down and ate her own portion.

My sister didn't seem to mind our cold attitude; she was happy as long as we ate all the breakfast she made.

After we finished eating, my sister cleared the table and prepared our things for school.

I stared at my sister's trembling bottom, wishing I didn't have to go to school and could stay home and spend some quality time with my sister. But every time I thought of my sister's hairy, plump vulva, I would simultaneously picture my sister's pubic hairless little slit in her pubic area.

Oh, damn it! I can't forget what my sister looked like last night.

Although she seemed disgusted with me, I was sure she was just masking her inner fear—the fear of having incestuous thoughts. I was even certain she was excited too, that she shared the same desires as me.

Just then, a horn blared outside, and my sister and I jumped up simultaneously. It was Billy, who lived across the street. Billy and I were good friends, the same age, but he already had his own car, and he would give us a ride to school every day.

My sister and I rushed towards the door, but got stuck in the narrow entrance.

"Get out of the way!" my sister shouted.

"No! You're blocking my way!"

We pushed and shoved each other, trying to get out before the other.

Suddenly, I did something mischievous, my hand sliding across my sister's chest.

Oh, great! My hand brushed against my sister's breast; although small, it was much firmer and more elastic than my sister's.

Just as I was reveling in this, my sister pulled back and punched my shoulder hard.

My sister came over, separated us, and then pushed us out the door. She gently patted our bottoms, telling us to stop fooling around. My sister had clearly seen our earlier antics; after pushing us out the door, she stood there lost in thought for a while.

It was another rather boring day. Sitting at my desk, the only thing I could think about was women's vulvas. Of course, I mainly thought about my sister's vulva; after all, it had been several days since I'd touched her, and the thought was exciting. However, my mind kept drifting to my sister's pink vulva, and I couldn't shake it off.

Although I had a physical relationship with my sister and could enjoy her beautiful, mature body at any time, it didn't stop me from thinking about other women. After all, I was still just a nineteen-year-old boy, still quite impulsive.

After school, Billy drove up and told us to get in his car.

His car was already full of other students, so after I sat down, my sister had nowhere to sit except on my lap. I didn't know if she would get in or take another car, but unexpectedly, she climbed into the car without hesitation and sat on my lap.

As she climbed on, I stole a glance at her thighs, which answered the question that had been bothering me during breakfast—I could vaguely see her pink panties. Just like at breakfast, my penis instantly became erect. When my sister sat on my lap, the head of my penis was pressed directly against her buttocks.

I had held my sister countless times before, and she had sat on my lap more than once or twice, of course, that was when I was little, but I had never felt anything. Now, I truly felt the pressure that my sister's buttocks and thighs were putting on my penis, making me want to explode.

As if to embarrass me, my sister's buttocks swayed from side to side with the bumps of the bus, making me even more uncomfortable, while she chatted with the other students on the bus as if nothing was wrong, occasionally flirting with Billy. My sister's buttocks

were moving a bit exaggeratedly, but I pretended not to care and listened to their conversation with interest.

When we crossed the street, Billy suddenly turned to avoid the red light, and everyone was caught off guard, their bodies leaning to the right. I was sitting on the far left, so I naturally grabbed the bike, while the others grabbed me. Reflexively, I wrapped my right arm around my sister's waist.

We only sat up straight when the bike was balanced. My hand accidentally slipped from her waist and landed between her legs, pressing against her slightly raised mound. A soft, warm sensation immediately spread through the back of my hand. I casually moved my hand away and placed it on her right leg.

My sister hadn't said a word to me or reacted to our physical contact, but when my hand touched her mound, her body suddenly stiffened; her abdominal muscles contracted and tensed, but she didn't move away. Only when my hand was on her right leg did she relax.

Afterwards, we continued talking and joking with the others, but clearly, neither of us was really interested in the mundane conversation. I was still savoring the brief contact, and I think my sister was savoring the same thing as me.

We arrived home, and I helped my sister out of the car. My right hand naturally reached under her buttocks and lifted her up. Of course, I'd done this hundreds of times before, but never had it felt like this. I could feel the elasticity of her slightly thin buttocks, and the softness of the deep cleft between them.

Oh! I couldn't hold back anymore; my penis was throbbing painfully.

I followed my sister out of the car, chatted with Billy for a bit about the basketball game that was about to start, and then said goodbye.

My younger sister was already in her room, and I ran in after her. My older

sister wasn't home; her sports car was gone. She always worked late, and after Dad eloped with his secretary, he left behind a bill that my sister had to pay.

I went to the kitchen, grabbed a sandwich, and wandered around, munching on it. When I got to my sister's room, I saw her door was open. This time, it was obviously intentional, since she must have heard all the clattering I'd made in the kitchen. My sister was sitting on her bed, wearing a bikini bottom and a nightgown over it.

Oh, it's only four in the afternoon!

I leaned against the doorframe, brazenly watching her. She pretended not to see me, and after a while, she looked up.

"Why don't you leave me alone for a bit?"

I just stared at her, focused on chewing my sandwich.

"Why are you always sneaking around, brother? You've been spying on me!" This time I nodded.

"Yes, I like to peek at you, little sister!" I said with a grin. "I often peek at you from outside your window and take pictures of you, but I never thought I'd be standing in front of your door... You seem to 'never' close the door." Her lips suddenly curled up, making her breasts bulge out of her nightgown, looking even more alluring.

"This is my room, you have no right to invade my privacy." "What privacy?" I retorted. "You leave the door open as if you're inviting the whole world in. If you really want to keep any privacy, then please close the door." My sister's face flushed red, and she jumped out of bed.

"Okay! I'll close it right away!"

My sister rushed over and tried to slam the door shut. Her nightgown was half-open, revealing her pointed, perky breasts, like two pink ice cream cones topped with two bright red cherries.

Oh, the fire in my heart was ignited again!

My sister slammed the door shut, and I quickly stuck my foot in the crack and used my shoulder to push the door open.

"Hai! Wait a minute, I'm sorry, little sister, I really didn't mean to upset you." She hesitated for a moment, and I gently pushed open her door and went into the room.

"I wasn't spying on you, after all, your door was open," I sat down on her bed, "Besides, could I see more than last night?" My sister immediately glared at me.

"How dare you say that, brother! Wouldn't you dare say that to anyone else?" I suddenly became angry.

"Who says I wouldn't? You're too presumptuous, little sister!"

My sister softened and walked to my side: "Well, brother, you won't tell, right? Sister will be angry if she finds out." I knew my sister would understand, but this was my chance.

"Okay, I won't tell, little sister," I assured her with a smile, "It's a secret between the two of us, right?" I slowly unfolded my scheme, implying that she had no choice but to obey me. I would tell her what I was going to do, I assured her she would be very happy, and she would definitely like it.

“Besides,” I added, “you saw mine, and I saw yours. We saw just as much. After all, I’m your brother, you have to believe me.” I placed my hand on her thigh. She trembled slightly but didn’t pull her hand away.

“Listen to me, little sister,” I continued, “everyone does this. You’re not the first girl to masturbate, understand?” As I said this, I couldn’t help but laugh. I remembered the first time I saw my sister insert a toothbrush into her vagina. Of course, after I came along, she no longer needed a toothbrush.

My sister sat on the bed, head bowed, silent for a while, before taking my hand.

“I don’t know why I did that, brother, but I felt so happy inside, it felt amazing.” “I know what’s going on, little sister.” I gently patted her leg and began to gently stroke her thigh. “It’s natural.” My hand slowly slid up her thigh, feeling the warmth and smoothness of her skin. My sister’s body was stiff, trembling as I touched her. Her hands weakly gripped my wrist, but she didn’t try to stop me. My heart began to pound, because my hand was about to touch my sister's panties for the first time.

It seemed I had to go further!

"Brother," my sister whispered, her voice clearly tinged with fear, "No, no, don't..." I ignored her and continued to stroke her thigh, getting closer and closer to the edge of her panties. My sister's hands gripped my wrists, but she neither stopped me nor tried to guide me.

"Brother, I'm scared..." she finally pleaded.

I knew this was true; after all, it was her first time, and if I couldn't ease her tension, she would definitely refuse me.

"Don't be afraid, sister. I'm your brother, I won't hurt you. I'm just continuing what you did last night, don't you think it felt good?" She still kept her head down, but her chest heaved violently, showing her excitement.

"Yes..." she murmured.

"Then, relax, relax, if you keep being so tense, your brother can't do anything." I picked her up and gently placed her on the bed. She resisted slightly, then blushed and obediently lay down, her eyes closed, her body sprawled out. My heart began to pound wildly; I knew what I had prayed for was about to happen.

"Open your legs, sister," I said, trying to be gentle and calm, but a tremor still lingered in my voice.

My sister's eyes were tightly closed, her head tilted to one side, looking completely helpless, but her body was gradually relaxing, her stiff thighs softening.

I used a little force to open her legs. Her panties were pink and semi-transparent; her thighs were smooth and elastic like cream, feeling wonderful to the touch—truly befitting a young woman.

My hands slowly and carefully slid along my sister's firm thighs, feeling their smoothness and softness. I could feel the intense throbbing of the veins inside her thighs; her body temperature was rising rapidly.

Through the semi-transparent panties, I could vaguely see the slightly bulging cleft; it appeared hairless, but I knew it was actually covered with fine, soft, golden-yellow hairs—perhaps in less than two years, a lush forest would grow there.

My fingers slid inside my sister's panties, slowly tracing the edge, making her gasp and her chest heave, but she didn't stop me at all. Although her body was trembling and she looked scared, she controlled herself well. My

experience from my older sister told me that it was time to take off her panties; further teasing would only backfire.

So I withdrew my fingers and gently patted her mons pubis: "Lift your butt a little, little sister." She lifted her buttocks slightly, and I reached under her buttocks and carefully pulled off her thin, seemingly easily torn panties. When

the panties were off her buttocks, I saw my sister's untouched virginity at such close range for the first time. The distance was incredibly close, much more stimulating than seeing it vaguely from the doorway.

The curves of her mons pubis were very soft, with fine pubic hair covering the entire mons pubis, but the pink labia were completely bare, making them very striking. My sister's lower abdomen was very flat and smooth, sloping down to curve gently into a beautiful arc where it met her slender thighs. Above this were two surprisingly large, tightly joined pink labia, forming a deep, folded groove that protruded from the mound. The groove looked very deep, the two sides joined so tightly that I couldn't see what was inside, but I knew it must be very moist and narrow.

I thought of my older sister's vulva. Her pubic area was covered with thick, dark pubic hair, which would secrete fluid with the slightest stimulation, making it constantly moist. The opening was open, making it easy to insert a finger. However, my younger sister's labia were tightly closed and hairless. Forcing entry would definitely be painful. At that moment, I unexpectedly felt a surge of intense pleasure.

The thought of my younger sister's cute little hole below that little crevice, and that I could soon insert my already throbbing, thick penis, excited me to the point of being unable to control myself.

After I completely pulled down my younger sister's panties, she whispered to me, "Don't hurt me, brother! I'm afraid of pain!" "I'll be careful, sister! I'll be very gentle!" Of course, these were just words of comfort; I didn't intend to keep them.

What virgin doesn't experience pain the first time? Although I had had sexual relations with my older sister for several months, my younger sister was still a virgin. My older sister couldn't possibly teach me how to avoid hurting a virgin. In fact, if my younger sister hadn't reminded me, I wouldn't have even considered that a woman's first time could be painful.

Even so, I decided to be as careful as possible during my actions, lest I spoil my sister's mood. If things went wrong, it would be difficult to handle later. I placed my burning palm on my sister's vulva, my palm against the vaginal opening, and slowly, gently stroked it. I didn't want to act rashly. Although I had no experience, I knew that dealing with a virgin required patience. I should proceed step by step, reaching my final goal gradually.

My sister clearly responded to my touch; her body trembled slightly, and she let out moans, not from fear, but from excitement. Her body twisted back and forth, trying to avoid my advances. Her shoulders swayed up and down, making the two small peaks hidden under her thin nightgown appear and disappear, making me unable to resist reaching out and ravaging them.

I felt my lower body growing harder and harder, desperately trying to break free of my underwear. But I dared not stop stroking my sister's vulva to take off my own underwear, because I worried that might cause her to stop my further actions. So, I could only endure the pain of my glans being tightly constricted by my underwear and continue to caress my sister's increasingly aroused vulva.

My entire palm was flat against my sister's mound, my fingertips gently tracing her flat abdomen, and then I gradually increased the pressure of the massage. First, I slid my palm down the curve of the mound to between her legs, my middle finger gently tapping the shallow groove, then my palm slid up over my sister's vulva, using the back edge of my palm to firmly massage the cleft. Repeating this, I soon felt the heat emanating from my sister's area, and it became increasingly moist; I knew my efforts were making progress.

I massaged my sister's vulva even harder. Each time my palm slid over, I would squeeze my middle finger a little inside my sister's vulva, maintaining a limited level of stimulation.

My sister was clearly enjoying it; her legs were wide open and relaxed. My other hand wasn't idle either; it was on her thigh, stroking the inside of her thigh back and forth, while preventing my sister from suddenly clenching her thighs.

Looking at my sister again, I saw her eyes slightly closed, her face flushed, her nostrils trembling slightly, and her small mouth half-open, emitting faint moans. She was clearly enjoying my ministrations.

I decided to take it a step further, so I gently probed with my middle finger, sliding it into my sister's vagina.

Oh, my sister's vagina was so hot and tight! I couldn't wait any longer; I had to take a stronger approach!

I could feel that my sister's vagina was already very wet; the secretions, though not plentiful, were quite lubricating, viscous, and sticky. As my finger probed further, I encountered a thin barrier.

Oh, God, it was my sister's hymen!

Because my finger touched her hymen so suddenly, my sister's body trembled reflexively, and she grabbed my hand, preventing me from going any further.

"Gently, brother!" she groaned, "It hurts." "Okay, okay!" I comforted her.

At that moment, a completely unfamiliar sensation enveloped my entire body. I don't think I truly cared about whether my sister would get hurt, nor did I care about anything else; I only cared about one thing—possessing her. It was a wild, instinctive, or perhaps masculine impulse. My sister had completely softened, was aware of being violated, and was already wet down there. What was I waiting for? I wanted to violate her! I wanted to fuck my sister!

Instinctively, my fingers plunged deep into my sister's vagina. My sister arched her back in pain, tears streaming down her face. She gripped my hands tightly, preventing me from taking another step, and simultaneously let out a scream—not loud, but chilling. I quickly pressed my body against hers, covering her mouth with my hand. She could only whimper and couldn't make a sound, but she desperately tried to push me away.

I held her tightly, my fingers still inside her, but my mind was filled with memories of our childhood. Back then, my sister liked to play horseback riding with me, of course, she was always the one riding me. I never imagined that one day I would be straddling my sister, my hard penis pressed between her legs, my fingers controlling her vulva.

My sister's body twisted, protesting my broken promise, tears of pain streaming down her cheeks, her eyes filled with a mixture of pain and anger. But she didn't really want to escape my violation; I could sense that, because she had begun to respond to me.

My sister's thighs didn't close due to the pain; instead, they spread even wider, and she also thrust her small buttocks to meet my assault, allowing my fingers to penetrate deeper into her vagina. However, she was undoubtedly angry at my sudden action, so she bit the hand I was using to cover her mouth, causing me to quickly pull my hand away in pain.

"Why are you biting me! Isn't this comfortable?"

"If you don't take your hand away, I'm going to suffocate, you idiot! And you're hurting me so much, take your finger away!" "I swear I won't hurt you like this again, little sister," I gently comforted her, "It hurts, doesn't it? But you actually like it, right?" "No! Take your hand away, or I'll scream." "Then if I leave one finger inside you, but don't let it move, would you feel better?" "I... I don't know." "Okay, then how does that feel?" "It feels much better. But don't poke too hard, or it will hurt a lot." I slowly moved my finger back and forth: "Does it feel better?" "Mmm... mmm, good, so comfortable, what, what is this feeling..." My sister panicked.

"Okay, if you can open your legs a little wider, I promise you'll feel even more comfortable." My sister shyly spread her thighs wider, making her private parts more prominent. Her small, hairless vulva looked like an open mouth, swallowing my fingers. I could even feel the faint suction from deep within that little "mouth."

Oh, it's a miracle I've been able to endure this long!

"That's good, little sister," I encouraged.

At this point, I could no longer bear the throbbing pain between my legs. I felt it was time to release my penis, which had been hard from the beginning. I stood up, pulled my fingers out, and my sister immediately grabbed my hand, somewhat reluctantly.

"What are you doing, brother?"

"Nothing, just want to give you a surprise," I said, taking off my clothes.

My sister clearly realized what I was about to do: "Oh, no! Brother, you don't really want to do that, do you?" "Oh, don't worry, I just want my little bird to be able to fly freely. It's been holding back for so long, it's so eager to fly. Look, like this." I suddenly pulled out my long-dormant penis. The newly released male symbol bulged out, pointing straight to the sky, radiating heat, the stubborn glans with its prominent veins, frighteningly red from friction with my underwear. My sister's eyes widened instantly, staring in disbelief, as if she had seen a venomous snake, a look of fear on her face.

"Sigh...okay, okay. Brother, you don't mean to use it to insert into your little sister's pussy, do you? I've seen some introductions in books, and if I do that, I'll get pregnant." "Of course not, little sister," I shook my head. "What will I do if you get pregnant? I'll be locked up in prison for a thousand years, right?" "I think so too." My sister relaxed.

"I don't want to spend the rest of my life in prison just to make my cute little sister happy." After taking off my cumbersome clothes, I bent down and placed my palms on my sister's vulva again. I really like looking at my sister's pussy; it arouses me easily.

When my fingers squeezed into her vaginal opening, the two pink labia, which were originally tightly stuck together, would suddenly open, sucking in my fingers, and then a warm, moist feeling would come from my fingertips, making my heart flutter.

I pressed my body against my sister's body again, and she cooperated by opening her thighs a little more to make it easier for me to enter.

I inserted my middle finger into my sister's vagina again. This time she didn't resist, and from the sensation of my finger entering, I knew she was completely wet and slippery, without the obstruction I felt the first time. I knew I didn't need to waste any more time. My finger began to move deeper, and this time there was no resistance. My finger rhythmically moved in and out of my sister's vagina, just like she had done the night before.

My sister reacted quickly; she began to writhe and moan beneath me, her hands gripping my back tightly.

I used my other hand to hold my sister's small, lovely breasts. Her breasts were indeed still small, after all, she was not yet nineteen, but they had already developed to the size of a peach, just the right size to fit in my palm, soft, firm, and elastic—irresistible to the touch. I gently rubbed her breasts, enjoying the delicate skin of my sister.

"Oh...oh...this...is so good...brother...it feels so good...so good...brother...make your sister feel even better..." "Open your pajamas a little wider, I can't make you feel better through them." My sister wriggled beneath me, fumbling for a while before unbuttoning her pajamas.

If my sister and I were doing this together, I wouldn't be able to resist tearing her pajamas off in less than five seconds, because she sometimes likes me to use a little force. But if I treated my sister the way I treated my sister, she might have a completely different reaction, so I wanted her to do it herself.

In just a moment, my sister had completely unbuttoned her pajamas, exposing her chest, leaving her slender figure naked in front of me.

"Wait a minute," I said, taking off my shirt as I did so.

"What are you doing, brother?"

"I'm going to take off my shirt and feel your breasts with my chest." "Just the shirt, brother, don't take off your panties!" "Okay, just the shirt." I took off my shirt, leaving my upper body naked. Although my panties weren't completely off, they were pulled down to my buttocks, and my thick penis was no longer restrained, just waiting to thrust in.

I held my sister in my arms. Her body was burning hot, and the faint scent of her virginity wafted into my nostrils, constantly stimulating my nerves. My hands continued to tease my sister's vulva, distracting her attention, concealing my throbbing penis as it approached her entrance. At this

moment, the head of my penis was already pressed against my sister's vulva. It seemed that nothing could stop my member from entering.

I remembered that I had promised not to insert my penis, but how could that be? Now I was already on the verge of death, and had no choice but to release it. What promise? Forget about it. I was going to give my sister a real touch! I was going to violate my sister!

Although it's the most ordinary thing in the world, I was still stunned when my sister's soft little mouth came to me. She took the initiative to kiss me.

A brother and sister kissing—this is different from a kiss between a man and a woman; it's an incestuous kiss! Oh! Just thinking about it is incredibly exciting.

My sister seemed very passionate, without a trace of affectation, natural and beautiful. Her thin lips were very soft and moist, and her kissing technique was quite clumsy, but her passion was irresistible.

My tongue quietly slipped over, gently sliding across her lips and teeth. My sister opened her mouth on her own, and my tongue explored. My sister's kiss felt completely different from my sister's. How to describe it? It had a refreshing quality, a natural, wild, slightly rough, unadorned kiss. Her tongue was soft, moist, and sticky, and when it intertwined with mine, it almost made my soul leave my body. My sister sucked on my saliva forcefully, her tongue passionately entwining with mine, as if trying to suck me in completely.

I felt her lower abdomen rubbing against my groin, making me unable to suppress the urge to violate her. Her hips swayed from side to side, allowing my fingers to give her stronger stimulation. Clearly, my sister wanted more intense stimulation; when my tongue touched her, her lower body began to writhe restlessly, rubbing against my groin, her hands stroking my back, seemingly encouraging me to take a more direct and daring approach.

I felt her abdominal muscles contracting repeatedly; obviously, the existing stimulation was no longer enough for her. It seemed I should take my final step.

I increased the pressure slightly, forcefully kneading and squeezing my sister's breasts, while vigorously sucking on her lips, my body rubbing against her skin, stimulating her senses. Soon, her breathing became heavier, and her movements became more frenzied. Then, my fingers no longer moved slowly in and out, but began to stir forcefully and arbitrarily, intensely stimulating her vaginal walls, causing them to secrete more fluid.

I carefully added one finger into my sister's narrow vagina, then another, and to my surprise, both went in smoothly.

My sister clearly sensed my actions. She gasped, her thighs tensed for a moment, then relaxed, letting out a pleasurable moan.

My fingers began to try and pry open her narrow opening. It was incredibly tight; the muscles at the vaginal opening contracted repeatedly, gripping my fingers tightly, making it difficult to begin my work.

Each time I pried open her vulva, she cried out in pain, but she never made me stop, cooperating by opening her thighs.

I focused my attention on a protrusion inside her vulva, gently pinching it with three fingers, wiggling it from side to side, occasionally teasing and squeezing it. My sister was clearly very sensitive to this; she arched her hips, swaying them, her lower body rubbing against my wrist, making the contact between her vulva and my palm even closer, letting out bursts of pleasurable moans.

I took a deep breath, lifted my body slightly, allowing my waiting penis to enter my palm, guiding it to the opening of her vulva, then lowered my hips, and my penis slid into her narrow vagina through the opening created by my fingers.

My penis penetrated deeply, quickly surpassing the length of my fingers, and I immediately felt the pressure of my sister's narrow vagina. A warm, moist sensation enveloped my glans, the muscles around her vaginal walls soft and yielding, tightly enveloping my penis, making me feel like I was in heaven.

I subtly pulled my penis out, thankfully my sister didn't notice that my member had entered the forbidden zone she was so fiercely protecting, instead letting out a joyful moan. I knew she would discover my misconduct sooner or later, but because of the obstruction of her hand, my penis wasn't fully inside yet. I wanted to be fully inside before she noticed, so I suddenly forcefully spread my fingers outwards, and my sister immediately gasped.

"Oh, no, you're stretching it too wide, brother, you're hurting me." Using the passage opened by my fingers, I thrust my hips forward, simultaneously pulling my fingers out, and my thick penis smoothly penetrated most of the way in, the vanguard disappearing into my sister's untouched little cunt, completely merging with her.

At first, the younger sister didn't realize what was happening and even let out a happy sigh, but she quickly understood what was going on and her body froze completely.

"Brother, no! Brother, no, pull it out quickly!!!"

"Relax, little sister, this won't hurt you. I'll be gentle, trust me." "No, pull it out right now!" My sister gasped for breath, struggling desperately to escape my intrusion, but I held her down firmly, not letting her move an inch. Although I didn't move my penis, it was deeply buried in my sister's tight vagina. I could feel the strong contraction of her vaginal walls and the slight tremors. As my sister struggled, there was relative movement between my penis and her vaginal walls, and the close friction between them gave me great stimulation.

"Oh, brother, please pull it out, okay? It hurts so much down there, you're really hurting me." My sister couldn't break free from my control and could only plead softly, but I was unmoved.

"The pain won't last long, little sister." I comforted her and assured her, but I didn't really know if it was true, because I had never been with a virgin before, and besides, I didn't really care if my sister was in pain.

My penis was only halfway in, and my sister's vagina was the hottest and tightest I had ever experienced. I didn't want to give up halfway. However, my sister was clearly saying one thing and meaning another. Although she was subconsciously resisting my intrusion, weakly pushing against my body and trying to push me away, her thighs were spread wide open, allowing me to penetrate her freely, and she showed no intention of actually asking me to stop.

If my sister really wanted to refuse me, she would have tightly closed her thighs and pulled her buttocks back, making it impossible for me to insert my penis into her body. Realizing this, I ignored my sister's weak resistance and focused on thrusting deeper into my sister's tight, hot vagina.

I gently swayed my hips to make it easier for my penis to enter. My sister really wanted me to stop at this point. After all, she was only nineteen years old, and no matter how much her body developed, it couldn't reach the standard of an adult. It was really difficult for her narrow vagina to accommodate my thick penis, since my penis was quite large, and it would be a lie to say that it wouldn't hurt if I forced it in.

My sister pleaded bitterly, her nails scratching my back until it was covered in blood, but I completely ignored her, my mind only thinking about how to conquer my sister. I grabbed her buttocks to prevent her from shrinking back and straightened her body so I could more easily complete my actions.

My sister was crying and struggling beneath me, naked. Watching her, I felt a strange pleasure. Was I a sadist?

Just then, I felt my glans touch a thin barrier, making me stop abruptly. I knew that was my sister's hymen.

My sister clearly felt it too, stopping her crying and looking at me with fear, as if saying, "No! No!"

I hesitated for a moment, then resolutely thrust forward. My sister's body trembled, letting out a short, piercing scream, tears quickly filling her beautiful eyes.

In that instant, I realized I had truly hurt my sister.

I had actually broken my own sister's hymen! Oh, had I really done something wrong?!

But this thought only lingered in my mind for two seconds before being dispelled by the pleasure of my penis completely occupying my sister's virgin vagina.

Filled with fear, listening to my sister's painful cries, I excitedly began to slowly thrust my penis in and out. The pleasure from the friction between my penis and her vaginal walls constantly assaulted my senses. I grew increasingly excited, and my sister's cries gradually faded, replaced by moans of pleasure.

My sister was responding!

After thrusting like this for a minute, I felt a warm flow as my penis withdrew. I instinctively realized it was my sister's virgin blood.

Somehow, I suddenly felt that things were going very smoothly, and that I was doing the right thing. I slowed my movements, gently guiding my penis in and out of my sister's young vagina.

My sister had been responding to my actions. She had stopped crying, her head tilted to one side, her eyes tightly closed, her body completely relaxed, her hands clenched into fists, her legs naturally spread, allowing me to take the initiative. Her face was no longer as pale as before, but flushed, her nostrils trembled slightly, and she would inadvertently let out sweet moans. It seemed she was lost in the naked contact she was experiencing, completely immersed in carnal pleasure.

My penis had only just broken through her hymen, not even fully penetrated; just a shallow thrust was already bringing her unbearable pleasure. What would happen if I went in completely?

Her vagina was narrow, tight, hot, and lubricated; the sensation of entering and exiting was like ascending to paradise. I didn't want to cause her any more pain, so I was extra careful as I pushed further in, making sure not to hurt her.

My efforts paid off; my penis was completely swallowed by her tight vagina, and she showed no sign of pain. Her vagina was so tight, gripping my penis so tightly it felt like it was going to snap, almost making me ejaculate.

Fortunately, after several months of contact with my sister, I was no longer like a typical nineteen-year-old boy who would give in after a few clumsy touches. I had learned to control my orgasms, and I wanted to give my sister a real orgasm, because she seemed so eager for it.

I lowered my head and took my sister's small nipple into my mouth, beginning to suckle hard. My sister moaned immediately, her voice filled with pleasure. She no longer resisted me, but instead wrapped her arms around me, her soft little hands stroking my back, encouraging me to give her more pleasure.

I gently bit my sister's nipple, my tongue gently licking back and forth on her nipple. It seemed my sister liked this, because her thighs were trembling slightly, and her breathing was much heavier. This was an instinctive reaction, but I knew my sister had already enjoyed her first time making love.

I gradually increased the force of my thrusts, and my sister's reaction was very enthusiastic. With each thrust, she would arch her hips to meet my movements, allowing my penis to penetrate completely. Each time I entered, our lower bodies would collide violently, making a "thump, thump" sound.

I reached behind her, lifting her buttocks so that each thrust would hit her hard and deep. My mouth left my sister's nipple and slid down to her neck, licking it with my tongue, making her giggle and tickle. She couldn't resist, and her lips met mine, and we began to suckle mouth-to-mouth. This time, my sister's passion was much more intense than before; her tongue intertwined with mine, greedily sucking my saliva, while her lower body moved rhythmically, receiving my thrusts.

I loved making love with my older sister like this, and now I also enjoyed this naked exchange with my wanton younger sister.

"Mmm...mmm...good...good...good, little sister!" Because of the kiss, I could only mumble, "Fuck you, little sister, brother loves fucking you, loves fucking your hot little cunt!" "Mmm...mmm! I like it...brother!" My sister moaned, "Fuck me...oh...violate me...brother...oh...oh...fuck me hard...fuck your own little sister to death..." At this moment, my mind was filled with nothing but the thought of fucking my sister, and everything in front of me became filled with lust.

My movements became rough, with big ups and downs, each time my penis was pulled out, it brought out my sister's pink and tender flesh, and each time it was inserted, it buried my entire penis completely into my sister's narrow and wet hole.

My sister writhed happily under me, writhing and submitting, flattering me.

Our limbs were desperately intertwined, sweat and saliva covered our bodies and the bed, and our lower bodies were completely wet, covered with my sister's lustful fluid.

My sister's passion was astonishing; she seemed insatiable, constantly demanding more from me. I, in turn, thrust my penis passionately, wanting us to reach the peak of pleasure together. At this moment, we were both completely immersed in the passion of incest.

Finally, I couldn't hold back any longer. My penis swelled painfully, and with a forceful thrust, my vagina suddenly opened, and a gush of hot fluid shot out, my semen gushing out like molten lava from a volcanic eruption, quickly filling my sister's wanton vagina.

I ejaculated and ejaculated for a long time, until I completely filled my sister's vagina, and then I stopped.

We were both exhausted, holding each other tightly, letting the lingering passion flow through our bodies.

By then, the evening sun had already set. Suddenly, I heard a faint sound behind me. I opened my eyes and looked up, only to realize that I had also forgotten to close the door. My sister was standing there by the door, watching us with a lewd smile.

Oh, what a lewd and embarrassing scene!

My sister and I were both naked, our limbs intertwined, I was on top of my sister, my penis still inside her vagina, milky white semen flowing from her vaginal opening, and our sister was standing by watching with a strange smile on her face. My

sister stood there watching us for a while, hesitant, unsure of what to do. Finally, she put a finger to her lips, signaling me not to make a sound, and then left, closing the door behind her.

My sister clearly heard the door close too. She opened her eyes, looked at me with a puzzled expression, and then looked towards the door. "Brother, what's wrong?" I shook my head and gave her a perfunctory reply. "Oh, nothing, nothing." I pulled out my limp penis, grabbed a towel, and wiped our bodies.

After our recent encounter, my sister's vulva looked red and swollen, her labia appearing even larger. She frowned whenever the towel touched it.

"Did you like it, sister?"

"Yes, of course I liked it, brother. If I had known earlier that it was so wonderful, I would have played with you every day." I smiled at my sister, lovingly stroking her pink vulva.

"Do you want to do it again, sister?"

"Of course!" she said happily, wrapping her arms around my neck. "Brother, I won't refuse you whenever you want." "That's called love, sex, sister!" I said, kissing her.

"Tell me, I want sex!"

My sister giggled, a little shy. "I want sex," she whispered.

"You'll get your wish, my little darling!" I said. "You have no idea how charming you are, even though you're still a child." "Really?" She laughed happily and said, "How do you know so much? Brother, have you... well... done this before?" "Don't worry about it, little sister," I dodged the question. "I think we should get dressed, otherwise my sister will be back." "I think we should be able to hear her come in." "I don't think so. If my sister's car is parked outside right now, I won't be surprised at all." A look of fear flashed across my sister's face. She quickly got up and looked out through the curtains.

"Oh God! My sister is back, brother!"

"I know, hurry up and get dressed."

My sister immediately put on her underwear as fast as she could. Suddenly she let out a scream, thankfully, not too loud. I turned around and saw that my sister had noticed the bloodstains on her thigh. I wiped them clean for her, then opened the door and let her take a shower in the bathroom.

A moment later, I heard the sound of water coming from the bathroom, so I went to the kitchen. My sister was preparing dinner in the kitchen, and when she saw me come in, she gave me an ambiguous smile.

I came up behind her, pressing my genitals against her buttocks.

"Was it good?" she asked with a smile.

"Of course, but I can still have another round with you before dinner, sister," I said, kissing her neck.

"What? You want more? You just finished with your sister, and judging from the way you two were just now, I thought you couldn't get up! How did she taste, baby?" "Not bad, but not as good as her sister!" Flattery never fails, and I flattered her, my hands kneading her full breasts through her shirt.

"You're so sweet!" my sister laughed and scolded me.

I turned my sister around and kissed her passionately.

My sister rotated her hips, her genitals rubbing against my lower body, and she looked very surprised when she realized that my penis was already hard.

"God bless you, my little brother! I've never seen you recover so quickly before! If this is because of what happened with your sister, I really hope you two can do it every day." My sister seemed genuinely happy.

At this moment, my younger sister finished her shower, and my sister and I separated, but unlike our usual sneaky interactions, we exchanged knowing smiles.

My sister continued to play the role of the older sister, showing no sign of having witnessed my sister and me having sex. My

younger sister looked completely different from usual, much more mature, radiant, and with a spring-like glow in her eyes. She was much prettier than her usual innocent self, every movement and smile exuding a seductive charm, making me want to hold her and do it again immediately.

During our dinner, my younger sister frequently gave me flirtatious glances. Taking advantage of my sister's absence, she leaned closer and whispered in my ear, "I won't lock my door tonight, brother." She then gave me an extremely lewd, seductive smile, before continuing to eat her dinner, completely ignoring my reaction.

After dinner, we watched TV in the living room. My older sister and I sat on the sofa, while my younger sister, as usual, sat on the carpet in front of us. My eyes involuntarily fell on my sister's parted legs, imagining her tight panties taut over her wanton vulva, which I had just penetrated, reminding me of the tightness of her tender little pussy receiving my penis.

Thinking this, my penis hardened again. My older sister noticed, reached over, and pressed down on the bulge in my shorts, vigorously rubbing it.

"Her ass is cute, isn't it, baby?" my sister whispered in my ear.

"Yeah! And a very cute little hole, sister," I whispered back, then unceremoniously grabbed my sister's left breast and roughly squeezed it.

"Will you go to her room tonight?" my sister asked, a half-smile on her face.

"Aren't you jealous, sister?" I said, my hand sliding inside my sister's skirt, touching her warm vulva.

"No, if you can satisfy your sister's needs anytime, I don't mind giving your sister some time too. I even want to join you two!" "What?" I was taken aback, my voice rising unconsciously. "You mean..." "Don't be so loud!" My sister was actually a little shy. "You're not the only one in this family who knows your sister has a small, cute butt, you understand?" I was stunned. I knew my sister was an extremely lewd woman; I'd been having sex with her almost every day for the past few months. But I never imagined she was interested in women, or rather, girls. My mind raced, picturing my sister, my younger sister, and me all in bed together. Oh, what an exciting moment! I was thrilled. In fact, this possibility was entirely real, especially after my sister and I had an illicit relationship. Persuading her shouldn't be too difficult.

"Okay, sister, leave this to me. I'll go find her tonight, make her happy, and maybe I can persuade her to join our threesome!" "I have a better idea, darling," my sister said, rubbing my penis. "Why don't you come to my room first? I'll let you ejaculate once, so when you go after your sister, you'll last longer and make her happier." "Yes, sister." I nibbled on my sister's earlobe. "I'll come as soon as my sister gets into bed." "I'll wait for you, little brother." My sister said, licking my ear and giving me a sexy, seductive wink before getting up to go to the kitchen to wash the dishes.

It's still two or three hours before my sister goes back to her room to sleep, but she seems a little restless. First, she took a shower, then walked back and forth in front of me in a transparent nightgown, fully displaying the mysteries of her not-yet-fully-mature body.

Every time she moved, her transparent nightgown clung tightly to her two small, firm breasts, revealing a pink cleavage below.

Oh, so my wanton sister wasn't wearing panties! Whenever her older sister wasn't looking, she'd spread her legs for me to see.

The thought of fucking her tight, hot pussy tonight made my penis impossible to calm down. Besides, I was going to fight both my older and younger sisters at the same time, which made me even more excited.

Finally, at ten o'clock, my sister went back to her room to sleep, giving me a flirtatious wink as she left, reminding me she'd be waiting for me all night. I winked back and watched her disappear down the hallway, swaying her hips.

A while later, my older sister finished showering and went back to her bedroom. I waited two minutes, then followed her upstairs, my penis, still throbbing with excitement, heading to my "flesh and blood" battlefield.

My sister lay naked on the bed, waiting for me, as always. As I pushed open the door, her eyes fell on the bulge in my underwear.

"Come here, my little brother," my sister chuckled, "You didn't stuff a banana in your shorts, did you? I've seen a bulge down there since this afternoon. Come here, let me help my little brother reduce the swelling." I took off my clothes as I walked towards my sister, my eyes fixed on the base of her spread thighs.

Under the light, it glistened, clearly already soaking wet; it seemed I didn't need to do any foreplay.

My sister's lower abdomen was flat, especially her labia, which were a bright pink and particularly plump.

My sister must have masturbated earlier to get me into the mood quickly.

As I undressed, my sister flaunted her full, plump buttocks, shamelessly opening and closing her thighs, making a squeezing motion, and clear, glistening vaginal fluid dripped from her plump, tender vulva, making my eyes almost pop out.

"Hurry up, baby!" It had only been a few days since we last did it, and my sister was clearly impatient. She said in a cloying voice, "Sister wants to suck on her baby brother's big ice cream first, come on." "I'm coming, sister, you slut," I said, thrusting my thick, long penis towards her mouth. "You're the star." My sister's hand was inside her wet, hairy cunt, and she giggled, looking extremely lewd. When my penis touched the corner of her mouth, she immediately gripped it with her hand, stroking it back and forth. Her slender fingers caressed the tip of my glans, and she licked my red glans with her tongue. A tingling sensation immediately surged through me, and clear fluid seeped from my mouth.

My sister lightly licked it with her tongue, her face leaving my penis. A thin, clear line connected us. My sister giggled lewdly, looking at me with captivating charm. Her two large breasts trembled with her laughter, creating a very pleasing wave of milk that made my eyes burn, my heart race, and my mouth dry.

My hand slid up my sister's long, slender thighs, gradually approaching the groin. When my fingers touched her fine pubic hair, my heart trembled involuntarily, for her tender vulva was right there beside me. Although I had visited this place more than once, I still couldn't help but feel excited every time I touched it.

My hand reached forward slightly and touched my sister's plump labia. I passionately caressed her protruding labia; they were soft, warm, and moist. My sister trembled and twisted uncontrollably from my touch. It seemed that my sister had been quite skilled at masturbation earlier. With my caresses, her vulva was overflowing with lustful fluids, her entire genital area was completely soaked, and the entrance was very slippery.

I added fuel to the fire by raising my middle finger and inserting it into my sister's vulva, digging and probing forcefully, making my sister's face contort with pleasure.

"Oh...oh...brother...so good..." my sister moaned loudly, her buttocks swaying excitedly from side to side. "So good...good little brother...oh...no...don't torture your sister anymore...oh...oh...no...don't touch your sister's flower core...oh...please...faster...oh...faster, put it in...oh...it's so hot down there..." "Sister, it feels good, doesn't it? It's so hot down there." I skillfully used my middle finger to go in and out of my sister's flesh hole. Her two plump labia tightly gripped my finger, and her erotic flesh rippled with my thrusts.

"Mmm...mmm...good...good...oh...oh...go in a little more...oh...good...sister's precious little brother...oh...oh...it makes sister...feel so good...oh...mmm...go deeper...oh..." My sister's moans were incessant, and her juices sprayed all over my palm.

I followed my sister's wishes and began to forcefully thrust my finger in and out of her erotic vagina.

My sister's vagina was as hot as a furnace, and her hot juices clung to my finger, making it sticky. The soft erotic flesh around my finger tightly wrapped around it, making me feel like I was inserting it into a pile of cotton.

My sister was panting, her buttocks thrusting upwards excitedly, matching my movements.

"Mmm...mmm...it's...so...perfect...little brother..." she moaned. "Good little brother...oh...oh...fuck my cunt harder...oh...oh...good...oh...I'm so lewd...oh...oh oh...so beautiful...I'm seducing my own little brother...oh...oh...it's amazing...ah...oh oh...good little brother...I want more...faster...faster lick my cunt...oh...I want to cum too...oh...oh..." Even without her request, I had already reached my limit. I loved licking my sister's wet cunt, sucking the salty liquid flowing from it, especially when she was extremely aroused, the secretions would increase dramatically.

I brought my head between my sister's legs, my tongue diligently licking her wet cunt.

I forcefully pushed my tongue into my sister's tightly closed vaginal opening, immediately feeling the heat of her tender cunt. The scalding hot vaginal fluid made my tongue tingle. I curled my tongue, and the vaginal fluid flowed into my mouth. I swallowed my sister's vaginal fluid in large gulps, my tongue also stirring around inside her vagina, making my sister's body shake incessantly.

"Good job, little brother!" she began to moan again, her genitals becoming increasingly wet. "Lick...lick...oh...oh...licking feels so good...oh...oh...baby...good little brother...oh oh oh...this...is so...perfect...oh...I'm going to die...good little brother...oh...you're going to kill me...oh...darling...good husband...oh...oh...sister...no...I can't take it anymore...oh...oh...I'm going to cum..." My sister kept moaning, happily babbling in her sleep. I was completely attracted by my sister's overflowing, hairy vulva, only knowing to wholeheartedly savor this familiar feeling and taste. My sister's hand groped around, spreading open her vulva.

"Oh...good little brother...put your tongue...in a little deeper...oh...don't...tease me anymore...oh...I can't take it anymore..." she gasped, shaking her hips, pressing her entire vulva against my face, grinding it hard, urging me on.

I straightened my tongue, trying my best to push it deep into my sister's tender vulva, I knew she liked it this way. My tongue wriggled deep inside my sister's flesh, forcefully striking the fleshy folds around her opening.

"Oh...oh...oh! That's wonderful, lick my clitoris!" My sister panted excitedly, clearly unable to bear the intense stimulation coming from her lower body. "Oh...baby...I'm so hot...hot...oh...I'm going to die of heat...oh...quickly...lick my clitoris...my clitoris can't hold back anymore...oh...oh...I want it so badly...oh...lick...lick...oh...oh oh oh...I want to cum more..." My target suddenly shifted to a small protrusion inside my sister's vulva, that was the clitoris, and if you attacked that spot, few women wouldn't surrender.

My sister's back was arched so high, her beautiful face was completely distorted with excitement, and her fingernails were digging deep into the muscles of my shoulder.

"Oh...dry sister...oh...good brother...sister is leaking so much...suck it quickly..." The sister gasped, her voice trembling with intense lust. "Suck sister's juices...oh...oh...you little rascal...bad brother...oh...oh...yes...like that...good brother...you're so good at it...oh...licking sister feels so good...oh...oh oh...dear brother...oh...I can't take it anymore...sister...can't...take it anymore...oh...oh...oh oh...sister is going to cum...oh...this time...I'm really going to...cum..." My tongue tightly circled the sister's clitoris, teasing it gently yet intensely. I used my hands to pry open the sister's two thick labia, put my whole mouth inside, and sucked on the sister's clitoris, my tongue swirling around the clitoris.

"Sister's going to cum!" Sister was already incoherent: "Oh...oh! Oh...oh...oh...oh! Suck sister's cunt...oh...good little brother...oh...oh oh...it feels so good to fuck sister...oh...damn it...sister's going to cum...faster...faster...oh...faster...suck harder...suck sister's juices out...oh...oh...suck...suck...oh...oh...oh...sister...cum...cum...cum...cum..." Sister's cunt was like an earthquake, the flesh was violently churning, the juices gushed out like a tidal wave, her body was convulsing like she had an epileptic seizure, her muscles were completely tense. I didn't stop working, while swallowing sister's juices in big gulps, I used my fingers to increase the stirring force inside her cunt, making sister reach the peak of madness.

"Oh, baby!" My sister's climax had finally passed, but her body was still trembling violently. She stroked my head and said, "Thank you, my good little brother. This time it was more intense than ever before. I've never experienced such crazy pleasure. Thank you, baby! You noticed too, didn't you?" "I noticed, sister," I replied. "Sis, you were so lewd just now." I sat up, licking the remaining semen from my lips, looking into my sister's lustful eyes.

My sister exhaled a long breath and looked down at my crotch. There was even drool at the corner of her mouth. Oh, she must be imagining how shamelessly she was licking and sucking her brother's thick, long penis.

"Little brother, you're fully erect, aren't you?" My sister said, stretching out her leg and playing with my penis a few times. "Oh, it's really hard, baby. Do you want me to give you some comfort?" I nodded quickly. My sister smiled and moved between my legs, kneeling on the bed, her snow-white, plump buttocks sticking up to the sky. Then she looked up at me, her face full of lewd smiles.

"Sister is about to give you the best service, so you have to hold on a little longer!" "Let's begin, sister!" I shouted, "Make me cum with sister's mouth." Sister grasped my penis, admiring it with awe. I saw that its urethra was already dripping milky white liquid, and the glans was erect, pointing menacingly at sister's nose, looking ready to pounce.

"Your baby is starting to leak, little brother."

"Lick it clean, sister!" I shouted.

"Of course I will, but you have to promise to shoot a belly full of semen into sister's pussy." "I promise, sister!" I couldn't hold back anymore. "Hurry up, sister, for God's sake, suck your little brother's cock!" "Okay, baby..." Before she could finish speaking, she suddenly lowered her head, opened her mouth and took my penis in, giving it a lewd kiss.

I trembled with pleasure, and my penis suddenly swelled up even more.

Sister gradually opened her mouth wider, swallowing my penis little by little, while sucking hard.

"Oh, sister," I gasped, looking down at my sexy, mature sister as she devoured my penis piece by piece. "This feels so good, sister, suck it, suck it harder, sister!" My sister had only swallowed a third of my penis, but she seemed to be completely filled by my thick, long shaft, almost suffocating. She closed her eyes, remaining still for a long time, as if gathering her passion, simply enveloping my penis with her sexy, warm lips.

Suddenly, her nostrils flared, and she began to suck my greasy, thick penis with great force, making smacking sounds as she sucked. Sometimes, she would inflate it like a balloon, blowing hard on the tip.

"Oh, sister, you're amazing!" I exclaimed, grabbing her hair and pressing her head down. "You're sucking so well, sister, suck it harder!" My hips thrust excitedly, my penis moving in and out with great enthusiasm, the glans mixing with my sister's saliva, filling her mouth completely.

"Oh...oh oh...oh...sister, this feels so good! Sister is going to suck out my semen." My sister passionately sucked on my precious little brother's throbbing, hard penis, her tongue licking back and forth around the glans. Clear lubricant kept seeping from my clitoris, and the sounds of her sucking were loud and unpleasant. My sister's right hand gripped the base of my penis tightly, while she vigorously stroked it back and forth, coordinating with her mouth movements to give me intense stimulation.

"Harder...harder...sister!" My face contorted with pleasure. "Oh...oh...I'm fucking you...sister...oh! I'm going to ejaculate! Oh...I'm about to ejaculate! Sister is sucking so well..." My sister used all her skills, doing everything she could to seduce me, her whole face, like mine, was shining with excitement, completely immersed in the pleasure of incest and depravity.

My sister's right hand frantically stroked the base of my penis, while her left hand forcefully squeezed my scrotum, the intense pleasure continuously stimulating my nerves.

I thrust my large, thick penis violently into my sister's lewd mouth. She had to use her teeth to stop my fierce assault; her teeth grazed the shaft with each thrust, intensifying my pleasure. Her

sucking grew stronger, my consciousness fading. Suddenly, a heat surged at the tip, and my pent-up semen erupted, shooting into her sensual mouth.

Hot semen gushed forth, the torrent splashing against her moving tongue, spraying everywhere. My sister was overwhelmed, only able to swallow my vomit greedily.

"Oh, baby!" When my semen stopped spurting, my sister gasped for breath before she could speak. "Sister really drank the most delicious milk, little brother. It's unbelievable how you could have so much semen!" "I have more, sister. Do you want to try some more?" "What about your sister?" my sister said. "She's waiting for you. Aren't you going to go right away?" "It's still early, sister." I rubbed my already somewhat limp penis and quickly made it stand up again.

"Lie down, little brother!" my sister said, pushing me down onto the bed. "You need to save your strength tonight. Now let sister give my precious little brother a full service." Could I say no? I could only nod and let my sister do as she pleased. My hard penis only wanted to enter my sister's hot, wet vagina.

My sister didn't waste any more time. She flipped over and straddled me. With a slump of her buttocks, her lower body swallowed my entire penis. Instantly, a soft, warm feeling surged into my heart.

My sister's plump, tight pussy was so cute. When my penis entered, the soft, fleshy flesh clung tightly to the shaft, the layers of folds on her vaginal walls rubbing against it, instantly giving me the urge to ejaculate. At the same time, my entire penis was completely immersed in her hot, wet juices, warm and comforting.

My sister clearly loved the feeling of being fully filled by my thick penis. When it was fully inside her vagina, she let out a long, comfortable sigh.

"Oh, my good little brother, I love your big cock! It's truly my treasure, so hard, so long, so full!" After my thick, long penis was completely buried inside my sister's pussy, she placed her hands on my shoulders and began to move her body up and down, diligently stroking my penis.

"Oh...oh...it's so beautiful...oh...oh...insert...insert...oh...good..." My sister started moaning again: "Oh...darling...oh...my pussy is so hot...oh...good...full...brother...oh...dear...dear brother's big cock...oh...it feels so good inside me...oh oh...oh...I can't take it anymore...oh...oh...harder...oh...yes...good...oh...good brother...fuck my hot, horny pussy hard...oh...oh...I want to cum inside...oh...inside..." My hand slid to my sister's soft, slender waist, pressing down on her white, plump buttocks. My sister writhed in pain, moaning, and I thrust my hips upwards, pounding into my sister's hot, fleshy hole. "

Faster, brother! Faster, thrust harder into my pussy! It'd be best if you fuck it raw, oh!" My sister arched her body, violently twisting her hips, her wet, hot vulva tightly gripping my penis, the jolting of her hips almost shaking my soul out of my body.

My sister's head was lowered, her long, disheveled hair hanging down, brushing against me and tickling me. Hot breath kept exhaling from her mouth, hitting my chest. Her breasts bounced in opposite directions with her movements, making my mouth dry. I couldn't resist reaching out and grabbing them, kneading them vigorously.

"Oh...fuck...fuck me to death...oh...oh oh...I like being fucked to death by my own brother...oh...oh...good brother...good fucking...oh...oh oh...my cunt is going to be torn apart by you...oh...oh oh...my cunt is so hot...oh oh...it feels so good to have my penis inside me...oh...oh...faster...oh...harder...oh...my cunt is going to be ruined by you..." I thrust faster and faster, almost every thrust penetrating deep into my sister's uterus.

My sister was now in a frenzy, uttering obscene words, her body writhing wildly.

I vigorously kneaded my sister's full breasts, pulling them from side to side, and pinching her erect nipples hard with my fingers.

My sister's abdominal muscles had already begun to contract violently, her body was spasming, and her vagina was in turmoil, the vaginal walls writhing violently, gripping my penis tightly. Her body was almost instinctively thrusting up and down frantically.

"Oh...oh...oh...oh...woo...oh...oh...oh oh...sister's coming! Oh...oh..." My sister's body trembled violently. She reached down, pinching her clitoris with her fingers as I thrust forcefully.

"Harder...harder...harder!...You're going to kill me, little brother...oh...you're going to kill me...oh...oh...baby...oh...good...oh...oh...dear little brother...bad little brother...harder...oh...oh oh...I'm so happy...I have a good little brother...oh...big stick little brother...oh...oh...my cunt will always be fucked by my little brother...oh...oh...good...oh...so comfortable...oh...so beautiful...oh...oh..." At this point, I had long since stopped listening to my sister's words, only knowing to fuck her hot, wet, and horny cunt hard.

"Fuck me to death!...Fuck me!...Fuck me!...Good little brother...Oh...Oh...Sister...I can't take it anymore...Oh...Oh oh...Sister is coming...Waaah...Waaah...Oh...Little brother...Sister feels so good...Oh...Oh...Sister can't hold back...Oh...Oh...Oh...Oh...Sister is coming...Oh...Sister is coming...coming...coming...coming...coming..." "Little brother's coming too!...Sister!...Sister!...Little brother shoots into you!...Oh...Little brother is going to shoot into sister's uterus!..." I was panting heavily, already a little out of breath.

Sister's vagina was convulsing violently, a hot current suddenly gushed out, quickly surrounding my penis, I shuddered, subconsciously thrusting a few times, using all my strength to thrust in hard, almost inserting my scrotum as well, the glans reaching the cervix, and then I ejaculated.

Thick, viscous semen gushed onto my sister's cervix, the intense pleasure leaving me weak and limp on the floor, my penis instinctively spurting out thick streams of semen.

My sister's body convulsed violently, her face flushed red, she clung tightly to me, her lower body throbbing incessantly, locked in a fierce embrace, not letting a single drop escape my ejaculation, as if trying to absorb it all into her womb, the muscles of her vaginal opening contracting and relaxing, desperately squeezing out every last drop of my semen.
