Get to know the sisters first, then the sister-in-law.

The young woman was only wearing a thin dress, her ample breasts and hips, slender waist and pink legs vaguely visible, exuding a captivating charm.

I peered through the crack in the door and saw her lift her dress with both hands, tucking it under her armpits, revealing her rounded buttocks encased in semi-transparent nylon panties. Then, she pulled the panties down and squatted down.

I saw a stream of urine shooting into the toilet bowl, and I saw her genitals. The stream of urine was shooting out from the center of her vulva, splashing and making a "drizzling" sound in the toilet bowl.

As she urinated, her legs were tightly closed, and she seemed to be enjoying herself.

Although she was young, she already had a fairly thick pubic hair, and her labia majora were slightly parted due to the effort, revealing glimpses of pink flesh.

After two or three minutes, the stream of urine stopped, and she wiggled her buttocks a few times, letting the last few drops of urine drip from her vulva.

Just as she stood up to put on her panties, I clapped my hands and walked in, startling her so much that she squatted back down, her legs tightly pressed together, and her hands hugging her knees.

I laughed, "A spectacle, a real spectacle! Little sister, I saw everything."

"You—brother—" The little sister was so flustered that her face turned red, and she couldn't speak.

I leaned forward, hugged her, and kissed her.

The little sister struggled a few times but couldn't break free. I then invaded her cherry lips with my tongue, entwining it with her fragrant tongue. Afraid of hurting me, she didn't dare to struggle too much. For a moment, she just trembled all over from my kisses, without any strength left.

Taking advantage of the passionate kiss, my hand reached behind her, unzipped her nightgown, and slipped inside to loosen her bra.

I pulled her dress down from top to bottom, kissing her bare, smooth shoulders, and gently pinching her sensitive little nipples.

My younger sister's breasts heaved rapidly, a tingling pleasure spreading from her chest throughout her body, and an itch rising between her legs.

"Brother, brother!" she whispered, her hands pressing tightly against my back. I inhaled her body's fragrance, my hands working even busier, tearing off her last remaining garment, a pair of panties.

I pressed her against the edge of the pool, lowering myself to press my lips against her alluring, mysterious place, passionately kissing that soft, dense area.

My younger sister trembled, arching her back, letting out a hoarse, lewd moan, "Ouch!" Then, her legs went weak, and her entire body sprawled out on the floor in a V-shape.

In my younger sister's fertile field, a strange moisture overflowed.

I buried my face in that mysterious place, greedily inhaling the fragrance, thirstily drinking in the spring-like fluids.

The little girl shook her hands violently, seemingly unsure of what she was doing. Her beautiful hair cascaded over her face, and she uttered dreamlike moans: "Mmm, brother, uh, I... I ca

n't take it anymore, oh!" I continued to suckle, my hands caressing her thighs, which only further aroused her, causing her body to writhe uncontrollably. She no longer cared about shame, raising her pink buttocks high, widening her entrance, revealing her most mysterious and unexplored area to me without reservation.

I stood up and stripped naked. Then I knelt down, taking the little girl's hand and guiding it to feel the heat emanating from my penis.

But when her hand touched it, she quickly pulled it back, her face flushed with embarrassment.

I admired her snow-white, delicate skin and her fiery body.

My younger sister's breasts were like newly sprouted bamboo shoots in winter. Although her chest wasn't very large yet, it was firm and elastic. Her whole body was snow-white and smooth, like the finest silk, and her slightly red areolas created a strong sense of sensuality.

I lowered my head, and she opened her cherry lips, which were full of desire, and let out a low moan.

My lips touched her fragrant lips, and in the instant her whole body trembled, I pressed down on her body.

"Mmm, mmm," she said, her jade arms tightly wrapped around my neck, her long legs spread apart, eagerly welcoming me.

Urgently, I moved my hand down, wanting my glans to be right at the entrance, but her hand beat me to it, and my penis was already in her jade hand. At this moment, my younger sister seemed to have lost all restraint, as if she had been enduring for a long time.

Upon touching that hard, thick, and hot penis, the young woman's hands trembled. She timidly asked, "How come your penis is so big? How can my little hole accommodate it?"

She gritted her teeth, sighed deeply, and finally made up her mind. Overcoming her fear, she guided the glans to the entrance of her vagina.

Her labia, hot with desire, pressed against the glans. I first gently rubbed the glans against the vaginal opening. How could the young woman resist such teasing? She gasped for breath, "Brother, please stop teasing me! I can't take it anymore!"

Hearing this, I chuckled and teased, "Lanxiu, didn't you used to forbid me from kissing you? Now you're letting me in even this last stronghold?"

My little sister blushed crimson, rolled her eyes, pouted, and pinched my ribs hard, saying coquettishly, "Hmm, I won't do it anymore! You always bully me, and you're acting innocent after getting the benefit!"

I laughed, "Okay! Brother won't bully you anymore. Now brother will let you enjoy yourself properly."

Hearing this, she held her breath, waiting for my thrust.

Her labia were incredibly soft, and her virgin vagina was so narrow; her vaginal fluid was just the right amount of wetness without being too slippery. I slowly pushed my penis in, and to increase our pleasure through full friction, she tried desperately to restrain herself from being too wanton, but ultimately couldn't resist and thrust her pink buttocks forward.

As my penis thrust into her, and she arched her back, the glans pierced her hymen.

Suddenly, the little girl screamed, her body trembling violently. Her legs clamped tightly around me, her lower abdomen heaving, her mouth agape, but she couldn't utter a single word. Her once rosy face turned deathly pale. After

a long while, she finally let out a long breath, her voice trembling as she said, "Ouch, it hurts so much! Brother, you've really ruined me! How can it hurt so much! You said you'd enjoy it, I'm not doing it anymore, hurry, hurry and pull it out!"

The young girl, experiencing the pain of inexperience, kept saying this, tears streaming down her face.

I had finally seized this opportunity, how could I just pull out whenever she asked? But seeing my little sister's deeply furrowed brows and tearful face, she looked so pitiful that I couldn't bear to force myself on her. So I put my mouth close to her ear and whispered, "Good sister, your hymen is already broken. Even if I pull out, it will hurt you. Why not bear with it a little longer and let us experience that unprecedented pleasure together?"

She looked at me, her eyes full of questions, and said, "Brother, is it really as good as you say?"

I smiled, encouraging her with my eyes, and said, "Yes, otherwise why would there be an idiom called 'male and female love'? That's what it's about. Women will feel pain at first, but after that, it's all enjoyment."

My little sister didn't speak at first, biting her lip and thinking for a while, before saying in a trembling voice, "Brother, you must love me well!"

Seeing that she agreed, I hurriedly and slowly pushed my penis in again.

She was so nervous that she was covered in cold sweat, and only breathed a sigh of relief when the head of my penis reached its end.

I knew that if I thrust in and out immediately, it would cause her pain again. In order to relieve her tension and also to rekindle her desire, I swayed my hips, making my glans rub against her inner walls, while gently kissing her lips and putting my tongue into her mouth to entwine with hers.

After a few minutes, my actions had taken effect. Her tears had dried, and her eyes now held a captivating allure. She occasionally let out seductive moans, her breathing quickened, and her lower body began to writhe. She said shyly,

"Brother, it's much better now. Hmm, whatever you want to do, I... I'll endure it."

She spoke her true feelings, her face flushing red again. She turned her face away, unable to look at me.

I chuckled, reached out and turned her face back to me, looking into her eyes. I said, "Little sister, I didn't lie to you! It doesn't hurt anymore! You don't have to endure anything, just feel it with your body."

The little sister answered shyly, gently pounding my chest with her small fists in agreement.

I placed my hands on her breasts, my lower body suspended in the air, supporting my weight with my hands and toes, like doing push-ups, rising and falling, my penis thrusting in and out.

My penis filled her vagina, making it feel full and airtight, her labia flipping up and down with each thrust.

She moaned softly, then cried out, "Oh, so good!"

Her eyes were glazed over, her mind seemingly elsewhere, her body automatically responding to my thrusts, allowing me to penetrate her fully.

I smiled at her, my hands roaming freely over her body.

Gradually, she forgot her girlish modesty, enjoying the sensation, her skin thickening with pleasure. She moaned incessantly, "Brother, it's so good, so wonderful! I was so stupid before, if I'd known it would be this good, I... I would have let you penetrate my pussy."

Her labia opened and closed, biting my penis, making popping sounds as the blister burst.

Hearing her moaning so enthusiastically only fueled my own arousal. I scooped her legs up onto my shoulders, allowing for a direct, deep penetration.

She gasped softly at first from the twisting pain, but then readily accepted the position, finding it more direct and stimulating.

Since we were on the floor, I decided to finish quickly to avoid ending up bedridden after our passionate encounter—that would be embarrassing.

So I relentlessly attacked her vulva. The room was filled with the continuous "plop!

plop" sounds of penetration, my glans pressing against her clitoris as I rotated my hips, experiencing indescribable pleasure.

My sister, too, writhed, panting and swallowing, her body glistening with sweat.

Suddenly, her body arched upwards, her hands gripping my shoulders tightly, her eyes rolled back, her mouth gaping open, only able to inhale but not exhale, then she exhaled forcefully, crying out, "Oh, uh, my little hole is blooming, um..." I hurriedly thrust even more wildly, my large penis erect, each stroke relentlessly penetrating deep inside, my hands reaching under her armpits, holding her shoulders to stabilize her body, preventing her from moving.

The little girl's legs swayed incessantly, her buttocks thrusting upwards repeatedly. Suddenly, I heard her cry out:

"Ugh, brother, I can't take it anymore. I feel like I need to pee inside, um... I can't take it!" With that cry, her body went still, a warm stream of vaginal fluid gushing from deep within her.

I quickly held my breath, feeling the impact from within her body. Seeing her already pale and exhausted state, unable to withstand my vigorous thrusting, yet still filled with fighting spirit, I couldn't help but smile wryly.

Just then, because the room was relatively quiet, I suddenly heard what sounded like someone breathing rapidly outside. I couldn't help but shout, "Who? Who's out there?" At first, no one answered, and the breathing stopped. I lingered on my younger sister, savoring this last moment of tenderness, too lazy to get up and look, thinking I'd misheard.

Suddenly, the door was pushed open, and my older sister, draped in a light veil, stormed in, her face full of anger, shouting, "What are you doing?" I was startled and felt deeply ashamed. Just as I was about to answer, I caught a glimpse of my sister's flushed face, struggling to calm her breathing, and a very obvious stain on the center of her dress. A thought struck me, and I chuckled, "Good sister, how long have you been eavesdropping outside?"

But my sister's eyes widened in anger, her teeth biting her lower lip, and she just kept breathing heavily, without saying a word. Suddenly, she jerked her shoulder, then couldn't help but smirk, saying with a hint of resentment, "You! Having your older sister isn't enough, why do you have to come and hurt your younger sister too?" I quickly retorted, "Sister, how can you say I'm hurting my younger sister? We should all enjoy ourselves! You've heard how comfortable I am!" My sister coldly snorted and spat, "Yes, you're all enjoying yourselves, you don't care about your older sister anymore!" I suddenly pulled out my penis, laughing as I ran to my sister's side, trembling as I said,

"Who said I forgot about my sister? I'm just waiting to serve you!" Caught off guard, my sister blushed deeply, and in her haste, turned to leave. But how could I let such a delicious treat slip by?

I grabbed her arm from behind with one hand, and with the other, I slipped under her armpit and squeezed her firm breast. This pinch further convinced me that my sister had been spying on me for quite some time, because her nipples had already hardened, like plump dates.

With a pull, my sister's body went limp, and she fell into my arms, her head tilting back, her hair brushing against my face.

My other hand covered her chest, one hand pinching one of her nipples, the other gripping and releasing her breast, occasionally pushing it with my thumb. I whispered gently in her ear, "Good sister, how could your little brother forget you?" As I spoke, I nibbled at her earlobe with my teeth.

My sister turned her face slightly, her cherry-like lips offering my lower lip, murmuring, "Silly little brother, how could your sister not know your feelings? We're family!"

Her lips left mine, and she leaned close to my ear, breathing heavily, repeatedly moaning, "Mmm...mmm...uh..." but her words were incoherent.

I rocked around like that for a while, but it wasn't very comfortable, and the movement was quite tiring, so I reached up and grabbed my sister's shoulders, slowly sitting up. My sister rested her chin on my shoulder and said in a sweet voice, "Good little brother, take your sister to heaven!" Sitting like that, it felt like my penis was buried in an abyss, unable to exert any force. I rocked around a few times, but my sister just clung limply to me.

I asked her, "Sister, can you feel your treasure like this?" She said weakly, "Of course I can. How can I not feel something so big inside me? But it's not a strong feeling."

I rocked around a few more times, but it wasn't very satisfying. My sister didn't move at all, and she wasn't cooperating with me.

I grabbed her legs and stretched them out behind me, then used one hand to support myself on the bed and the other to hold my sister's body, slowly pulling my legs out from under her buttocks and laying her flat on the bed.

I knelt between her legs; now it was time for me to unleash my power.

My sister spread her arms wide, her forehead already glistening with sweat, her skin a seductive crimson.

I grabbed her ankles, bending her legs so her heels were pressed against my buttocks, then I held her legs against my chest and began to thrust violently. My

penis, accompanied by the "slap, slap" of skin against skin, plunged in completely, again and again.

I spread her legs apart again, pressing her calves down to her chest, and then pressed her thighs back, spreading them apart and holding them down. This way, I could enjoy myself and clearly see the magnificent sight of our contact area.

My sister's already thick pubic hair, under the pressure and soaked with her vaginal fluid, appeared even more disheveled, yet its color was even darker and shinier, with many white, sticky substances clinging to it. After my penis was fully inserted, all that could be seen where our bodies touched was a patch of downy hair, except for two thick, tender labia in the middle, which rose and fell with each thrust of my penis.

I slowly withdrew my penis halfway, examining it closely. The front half was tightly wrapped inside her vagina, the labia stretched open, yet the inner walls were joined seamlessly, the lifted labia appearing extremely tender, making one's mouth water.

Engrossed in watching, I reached out and pulled her thighs close, thrusting into her relentlessly.

My sister's body went limp on the bed, sliding up and down with my movements, her breasts bouncing impromptu like two playful rabbits. But she lacked the strength to move much; she moaned, "Ah! Good brother...you...you're so...good...sister...so good!" Encouraged by her words, I became even more aroused, thrusting harder and harder. I had been off my sister for a long time.

Flesh against flesh made a "slap, slap" sound, and her juices churned with each "plop, plop."

My sister just kept moaning and groaning, her voice full of seductive allure.

After a few more powerful thrusts, I couldn't hold back any longer. I lowered myself, pressing down on her, my body trembling. My lower abdomen contracted and then released forcefully, and I ejaculated deep inside her vagina.

My sister was trembling all over, moaning, "Ah! Ah! Brother... Ah... So beautiful... Ah... So pleasurable... Oh... Oh... You... You're so amazing... My pussy... So beautiful... Ah... I'm ascending to heaven!" With that, her eyes rolled back, and she seemed to have no strength left to breathe.

I pressed her tightly against me, straddling her, all my strength seemingly drained away with that final thrust, and I no longer wanted to move.

Such a beautiful moment, yet what a pity! It was time to sleep. After that, sometimes my sister and younger sister would come to my room alone for penetration, and sometimes they would simply squeeze together on my big bed, with me straddling them both, and I would fully enjoy this bliss of having two women.

That day, I received a call from my brother saying he had to go on a business trip for a while and asked me to come over and keep my sister-in-law company when I had time. I told my older sister and younger sister, but they strongly objected, not wanting me to leave their side. However, while I was playing with them, my sister-in-law's beautiful face kept appearing in my mind. My sister-in-law is twenty-five years old this year, and she is very beautiful. Below her are a pair of bright eyes and a straight nose, and below that is a delicate and exquisite nose, plus a small and delicate mouth, which is indescribably alluring.

In fact, ever since my older brother's wedding, I have had a feeling of amazement towards my sister-in-law. I often dream of her as a lustful object, just like now, while I am penetrating my younger sister's vagina, I am imagining the scene of penetrating my sister-in-law's vagina.

So I simply called my sister-in-law and asked her to come over. Although my older sister and younger sister were a little unhappy, under my sweet talk and my vigorous thrusting, they had no choice but to agree.

After my sister-in-law moved in, we were all very happy together. We were all around the same age, but the sisters deliberately acted intimately with her, making sure I didn't touch them. I didn't dare be too forward in front of her, only secretly resenting them. Watching her go in and out of the house every day, my desire slowly consumed me.

Finally, one day, I had a chance. My older sister and younger sister went out, and I was reading in the bedroom. I heard my sister-in-law come home from work, and soon after, I heard the sound of running water from the bathroom. I quickly and quietly went to the bathroom door and peeked through a small hole I had dug beforehand.

My sister-in-law was already naked, standing in the room. Her figure was incredibly beautiful; any more would have made her look fat, and any less would have made her look thin. Her skin was snow-white, her neck smooth, and her breasts were round and prominent, the pink nipples standing out vividly against her white breasts like two cherries. Her buttocks were full and round, like an inverted gourd. Dark pubic hair covered her protruding mons pubis.

The sister-in-law tested the water in the bathtub with her hand, then carefully stepped in, standing in the clear, warm water.

She gently splashed the warm water onto her smooth lower abdomen, rubbing it up and down, before sitting down in the tub. Her fair, white body was completely submerged, with only her two jade-like feet resting on the edge of the tub.

The sister-in-law arched her back, pulling her lower body backward. The pubic hair on her genitals retracted, then leaned forward again, creating a messy scene around her vulva, with small bubbles occasionally bubbling from her vaginal opening. Her labia, affected by the bending and straightening of her legs, opened and closed intermittently, a truly beautiful sight.

The sister-in-law probably felt a slight itch inside her vagina, so she gently parted her labia majora with her right index finger. When her fingertip touched her clitoris, her sensation changed from itchiness to a tingling, numbing sensation, and her body involuntarily trembled.

She then pushed a section of her index finger into her vagina, gently twisting it. The itching intensified, and she leaned back against the bathtub, her head tilting back, moaning, "Mmm...mmm..." Her finger slowly continued to penetrate her vagina.

My sister-in-law and brother were newly married, only recently discovering the wonders of sex, and now she was alone in her room. Usually, she had me and my sisters to keep her company, so she didn't feel lonely, but her body still harbored desires. The touch of her finger was too much for her to bear.

I, watching from outside, couldn't resist either. My penis, throbbing painfully against my shorts, pressed against the door in my haste.

This startled my sister-in-law, who was taking a bath. She hurriedly asked, "Who is it?" "It's me—it's me—quick—quick, open the door!" "Little brother? What do you want?" "My—my stomach—it hurts so much, I—sister-in-law, open the door quickly!" "Wait a moment, I'll be done bathing soon." "I can't wait—hurry!" I deliberately added a few screams like a ghost.

I heard my sister-in-law emerge from the bathtub, water splashing on the floor, followed by rustling sounds. Then I saw her opening the door, wrapping a towel around her chest and thighs, and saying, "Come in, come in quickly!" My sister-in-law had long, flowing hair, and her whole body exuded the fragrance of bathwater and a uniquely feminine scent. She was only wearing a violet bath towel. She had a pair of shapely, long legs, and her exposed skin was as smooth as frost. Her arms were also round and smooth, soft and boneless. My sister-in-law's lips were half-pursed, and a blush of shyness lingered on her cheeks, clearly still recovering from the pleasure of masturbation. Her eyes were still hazy.

I held my stomach with both hands and slowly walked in. My sister-in-law hurriedly came over to help me, anxiously asking, "Little brother, what's wrong?" My face was flushed, and I did look like I had a medical emergency, but it was just a bit of a sore throat from watching so much. How could my sister-in-law know? She reached out and touched my forehead, and was shocked, not knowing what to do.

I quickly said, "Sister-in-law, go get me a wet towel to wipe myself." My sister-in-law hurriedly let go of me, walked to the edge of the tub, and bent down to wring out the towel. At that moment, her genitals were exposed from behind the towel, completely exposed to my naked body.

I pulled down my pants, and a hard penis immediately sprang out, now even more erect.

Seeing that the time was right, I immediately stood up, walked behind my sister-in-law, lifted the towel up, aimed my penis at her vulva, and thrust it in hard.

My sister-in-law suddenly felt someone attacking her from behind. As she tried to turn around, she felt something warm and hard gripping her vulva. Instinctively, she touched it and found a penis inserted inside her. She cried out, "Little brother, what are you doing? Take it out!" "No, no!" she cried, trying to break free, but I held her tightly from behind. I ripped off her towel and threw it to the ground.

Holding her inner thighs tightly, I parted her labia from the front, making it easier for my penis to enter. Then, pressing my head against her back, I forced her to bend over, exposing her vulva, and thrust powerfully into her.

Because I was pulling her labia too hard, my sister-in-law cried out, "Little...little brother...you...you be gentle...my...my little hole is almost torn apart by you...be gentle...be gentle...ouch...ouch...you...you're so hard...I'm going to...I'm going to die...ouch..." I ignored her cries and thrust in with all my might. There was a muffled "plop" sound as my glans hit something soft and elastic—it must be her clitoris.

My sister-in-law stopped struggling and crying out after that thrust, but her buttocks swayed back and forth with my movements, responding to my thrusts.

I released her labia, grasped one of her breasts hanging in the air with one hand, and began to knead it vigorously with my fingers. I pressed my body against her back, no longer thrusting forcefully, but simply keeping my penis deep inside her vagina, swaying it from side to side, occasionally making a few rotations.

My sister-in-law tried to straighten her back, but the feeling of having my penis between her legs was strange, and she couldn't move because I was pressing her down. My thrusting and gentle rubbing against her vaginal walls aroused her intense lust; she only wanted to be penetrated forcefully by my large penis. She didn't dare struggle too much, afraid that my penis would escape from her vagina. She could only endure this strange position. She kept moaning weakly.

While I moved my hips, thrusting my penis in and out, I used my hands to pull her breasts downwards. Her breasts felt numb and painful, yet there was a strange pleasure. She shook her head, moaning weakly, "No...don't..." My sister-in-law's hands supported her on the edge of the bathtub, her legs spread wide apart. From behind, her labia were turned back, her vaginal opening stretched wide by my penetration. With each thrust and withdrawal of my penis, her vaginal fluids splashed onto my testicles, thighs, and dripped onto the floor.

My testicles, stimulated by the hot, gushing vaginal fluid, throbbed upwards, an incredibly pleasurable sensation! I couldn't help but thrust harder and harder, feeling increasingly excited.

My sister-in-law's buttocks were raised high, and I almost always hit her G-spot from behind, making her moan, "Mmm...mmm...oh...oh...good...my...my little hole...so...so itchy...oh...mmm...little brother...you really know how...you really know how to penetrate...so comfortable...mmm..." My thrusts had almost completely turned her labia inside out. I slowly bit and nibbled at her back with my teeth, occasionally nibbling at a tender piece of flesh between my teeth. As I did this, my sister-in-law's body trembled uncontrollably, her buttocks moving even faster in response to my movements, swaying dramatically.

My lust grew ever stronger.

I released my sister-in-law's breasts, straightened up, pressed my hands against her beautiful buttocks, and looked down at my penis moving in and out of her vagina. The vaginal walls gripped my penis tightly, stretching and folding with each thrust. Most excitingly, my sister-in-law's anus opened and closed with my movements, the surrounding flesh taut.

I was incredibly excited. I gently pressed a finger against her anus, but her reaction was intense. She let out a long "Ah..." and her anus contracted sharply, almost pulling my finger inside. Then she grabbed my hand, trembling uncontrollably. I

could feel the walls of her vagina quivering, and even a force pulling at my penis from within, making thrusting even more difficult. With

my hand gripped, I twisted my wrist around hers, pinning her hand to her back, while my penis continued its relentless thrusting. My sister-in-law, supporting herself with one hand, was being pounded from behind, causing her body to sway even more violently, almost tipping over several times. Luckily, my other hand caught her slender waist in time.

After a few more thrusts, I finally couldn't resist my curiosity and asked, "Hey, sister-in-law, has your little asshole ever been penetrated by a cock?" As I asked, I rubbed the tender flesh around her anus with my fingers.

"Go away...who...who has ever heard of...penetrating an anus..." My sister-in-law gasped, rebuking my wild idea.

"Sister-in-law, you're so ignorant. Women don't necessarily need to use their vaginas to be penetrated. A woman's anus, like her mouth, can be penetrated. The anus works just as well as the vagina." I said with a laugh as I thrust my cock forcefully into her clitoris.

"Hmm...humph...I don't believe it...an anus...so small...a cock so big...how can it fit?" I laughed and said, "Sister-in-law, your little hole was just as small before it was penetrated, but now it's being penetrated by my big cock and you're screaming with pleasure!" "Go away...go away...I'm not enjoying it..." My sister-in-law was almost out of breath from my thrusting, but she still stubbornly refused to admit it.

I was angry that she was still putting on a brave front, so I pulled my penis out abruptly, leaving only the glans inside

her vagina. I left it there without inserting it further. My sister-in-law was moaning rhythmically with my thrusts, but suddenly she lost her target, and her vagina felt empty and uncomfortable. She turned her head curiously to see what was happening. In that instant, I suddenly exerted force, pulling her hips back with both hands, and thrust my penis in hard.

My sister-in-law couldn't withstand the force; before she could turn her head, it was thrown back, accompanied by a long, drawn-out moan, and she resumed her lewd moans.

I thrust a few more times like this, and seeing that my sister-in-law was no longer paying attention to what I was doing, I quietly wiped away the vaginal fluid and semen that had seeped out of her vagina with my fingers, carefully stroking it on her anus. Then I forcefully pulled out my penis, but instead of inserting it back into her vagina, I used my hands to spread her plump, white buttocks apart, wiping the deep cleft with her vaginal fluid.

My sister-in-law, panting, asked, "Little brother... what... what are you doing..." "I'm going to deflower your little asshole!" I said, aiming my penis at her anus and thrusting hard, half of it already inside.

This made her scream, "Ouch, it hurts, it hurts so much!" She cried out, twisting her hips, trying to shake off my penis.

But it was clamped tightly, and I couldn't shake it off. I found it difficult to exert any force; I couldn't go in or back out. I could only press down on her body and thrust forward forcefully, pushing my penis in a little further.

I leaned down and whispered in my sister-in-law's ear, "Good sister-in-law, don't move around. It won't hurt in a bit. It's the same as having your virginity broken. Maybe later, you'll even want my big cock to go in your ass!" At this moment, my sister-in-law wiggled her buttocks a few times, feeling the stinging pain gradually lessen. Her body calmed down, and just as she was about to speak, I started thrusting again. My cock scraped against the fleshy walls of her anus, and she felt another stinging pain. In her panic, she hurriedly cried out, "Ouch...no...it hurts..." I ignored her cries and just pressed my hands tightly against her waist, preventing her from moving much. Then I kept thrusting my cock in and out, each thrust deeper than the last. After a lot of effort, finally, my entire cock was inside.

My testicles slapped against her plump, white buttocks, the flesh hitting flesh making a "slap slap" sound, which further intensified my lust. I couldn't help but slap her buttocks with my hands while thrusting.

At first, the sister-in-law struggled fiercely, but then she lost all strength and could only moan, "Little brother... now I'm... you've... killed me..." After a series of thrusts, she felt the pain gradually disappear, replaced by a slightly itchy, tingling, and spicy sensation instead of pain. The thrusting of the big cock seemed to relieve the itch, yet it also seemed to tease it even more, a truly indescribable feeling. So the cries of pain slowly turned into moans, and then gradually into soft whimpers that only she could hear.

Feeling the pleasure, she couldn't help but raise her big, fat buttocks to meet the thrusts of the big cock, and at the same time, with the rhythm of the thrusts, she cried out in high and low voices, "Oh... good little brother... big cock... so powerful... oh... my asshole is so itchy... darling... thrust harder... thrust... ah..."

I thrust harder and harder, her little asshole twitching in waves, her vulva dripping with lustful fluid. My cock was now much smoother, making the thrusting even more pleasurable. Because of the force, my lower abdomen would occasionally slap against her plump buttocks, making a "slap, slap" sound.

My sister-in-law just panted, calling out "dear brother, dear younger brother" repeatedly.

I thrust hundreds of times in one go, and I couldn't help but pant a little. I leaned on my sister-in-law's back, slowed down, and asked with a smile, "Good sister-in-law, how does it feel?" "Comfortable...comfortable...your big cock...it feels so good inside my little asshole..." "I didn't lie to you, did I! You can have your asshole penetrated, right?" "Yes...yes...but little brother...you...you're making me...even more itchy...ah...my little hole...it's so itchy...ah..." Hearing this, I couldn't help but laugh loudly, thrusting my body against her back. My sister-in-law moved her buttocks and shoulders in protest.

I waited until my laughter subsided before panting, "Good...good...I'm willing to...die from exhaustion for you, sister-in-law, just to satisfy you!" With that, I thrust into her anus a few more times, then pulled out my large penis and shoved it into her vagina. The penis went in very smoothly; her vagina seemed to have been waiting for a long time, swallowing it whole.

I slowly pulled it out, then thrust it in again forcefully, each time almost hitting her G-spot. After dozens of thrusts, I didn't pull it out completely, but pushed it in as far as I could, the glans against the depths of her G-spot, rotating it up and down and left and right.

My sister-in-law's head sometimes tilted back, sometimes drooped low, sometimes swayed wildly from side to side, her long black hair fluttering, a beautiful sight. She moaned, "Mmm...mmm...ah...ah..." It sounded like a plaintive cry, but it only fueled my lust.

I pressed deeply into her uterus and vagina, leaving her completely powerless, only able to support herself instinctively with her hands.

I lifted her right leg and placed it on the edge of the bathtub, widening her vulva further. As I thrust forcefully, her pubic hair rubbed against the tender flesh exposed by her vulva, that sensitive flesh appearing exceptionally red after being rubbed. My sister-in-law screamed desperately, but could no longer utter a single word, only "Ah...ah..." Her labia, stretched wide by my penis, were repeatedly thrust in to the hilt, touching her clitoris, causing her to sway her hips as if in a frenzy.

Suddenly, her body convulsed, and as soon as my penis was withdrawn, her vaginal fluid gushed out, spraying onto my inner thighs and penis, covering them completely.

Stimulated by this, I could no longer restrain myself, hastily thrusting my large penis inside, gripping her buttocks tightly with both hands, my body trembling, and my semen also sprayed deep into her vagina.

My sister-in-law was utterly exhausted. Her arms could no longer support her body; her knees buckled, and she collapsed to her knees. Luckily, I caught her just in time, otherwise she would have fallen hard.

But I was too weak to continue; I could only hold her to slow her fall, but I too eventually slumped to the ground with her, my penis slipping out of her vagina.

My sister-in-law lay on the ground, her body curled up like a shrimp, her head touching the ground, her body still twitching intermittently, her breathing incoherent. Her lower body, now without my penis, still had her labia parted, her vaginal fluids mixed with my semen, slowly flowing down her vaginal opening onto the ground…
