Chapter 13: Wanton Intercrural Sex with My Sister

Chapter 13: Wanton Intercrural Sex with My Sister

The door handle turned with a soft click, and my sister poked her head in, cautiously sneaking into my bedroom.

"What are you doing up so late?" I asked suddenly from my hiding spot behind the door.

The room was unlit and shrouded in dim shadows.

Startled, my sister shuddered and immediately threw a punch toward me. "Are you a psychopath? Why were you hiding behind the door?"

I quickly caught her fist; the little girl’s punch actually packed quite a sting.

"You still haven't told me why you're sneaking into my room."

I walked over to the bedside and switched on the lamp. An orange glow flooded the headboard, bringing a sliver of light to the room.

My sister smoothed her chest with her small hand to calm her racing heart, then said huffily, "What, do I need to file a report just to come into your room now?"

She was wearing a one-piece nightdress that partially concealed her exquisite, graceful figure. Her beautiful hair draped naturally over her shoulders, and her fair skin shimmered with a white luster under the lamplight.

"Can't you respect someone's privacy?" I sprawled out on the bed and let out a long stretch. "Didn't you see your brother isn't wearing any clothes?"

"You want privacy in front of me?" My sister sat on the edge of the bed, her large eyes sparkling. She glanced downward. "Aren't you wearing panties?"

Because of her sitting position, her nightdress hiked up slightly, revealing a section of her snow-white, silky thighs.

"It's so late. What did you come here for?" I rested my palm gently on her thigh.

It was smooth and elastic.

My sister didn't pull away, but her expression was clearly uneasy.

She reached out her small hand to feel my forehead, asking with a worried look, "Brother, have you been possessed by something? You feel so strange lately."

I pushed her hand away. "Stop reading those brain-dead transmigration novels online."

"So you haven't been possessed?"

My sister pressed down on the hand I had on her thigh, asking curiously, "Then why are you always thinking about perverted things? And with your own biological sister, no less."

That phrase—"biological sister"—made my heart tremble.

"Lin Xi!" Unable to endure the throbbing in my heart, I pulled her into my arms and pinned her beneath me.

I lowered my head slightly, my nose brushing against hers. "Has anyone ever told you that you're very beautiful? And that you have a great body?"

A flush crept onto her face, and her breathing grew heavy. "Whether I'm beautiful or not... don't you already know?"

As she spoke, the fragrance from her small mouth wafted around my nose; it smelled wonderful.

I couldn't help but gently nip the tip of her nose. "Do you have any idea what a torture it is for me when you walk around all day without any concern for your image?"

"Is it?" Her gaze flickered, avoiding mine.

"During this summer break, you've been wandering around in front of me in your underwear every day, showing off your waist and those long legs. What kind of girl does that? Do you know how hard that's been for me?"

"Wasn't I always like that before?" Being pinned beneath me seemed to make her uncomfortable, and her delicate body squirmed restlessly.

"Before was before. Why don't you bring up the fact that we used to bathe together when we were little?"

"So just because of that, you've started having bad thoughts about your own sister?" She deliberately blew her fragrant breath into my face, her playfulness bordering on reckless.

"You..." I suppressed the urge to kiss her small mouth, let out a sigh, and rolled over to lie beside her. "Seriously, what are you doing in my room this late?"

"I wanted to see if you were angry." She giggled and sprawled across my chest, her hair falling onto my face and making it itch.

"What would I be angry at you for?" My hand found her slender waist. With a gentle squeeze, I realized just how thin it was.

She gave a soft hum and said sheepishly, "Didn't I just sneak away earlier?"

"What else were you going to do? Wait for Mom to catch us and break our legs?" My hand wandered down to her beautiful ass, gently squeezing and kneading it through the thin fabric of her nightdress.

Though her butt wasn't as plump or large as Mom's or Maternal Aunt's, it was sufficiently perky and soft. Most importantly, the shape was perfect.

Her face turned several shades redder. She let out an "Ai-ya" and slapped my hand away. "Brother, why are you so horny?"

"Who told you to come here and tempt me on purpose?"

She then lay down quietly beside me, saying nothing.

Just as I was wondering if she had fallen asleep, she suddenly turned on her side to hug me. Her peach blossom eyes were watery and bright. "Brother, do you like me?"

"Hmm?"

I looked at her lying on the pillow and studied her face: a flawless visage, misty peach blossom eyes, a petite nose, and red lips as enticing as rose petals.

She was only sixteen, but her body was developed far beyond her years—a slender waist topped with heavy fruit. Her waist was so thin it could be held in one hand, yet her breasts were perky and full, standing proud.

Sometimes at home, she would walk around in just her underwear, her full, beautiful ass swaying gracefully with every step, a sight that truly stirred the soul.

And then there were those long legs; they were practically longer than my life.

Breathing in the fresh scent of her body after her bath, I pulled her slender waist close. "I like you. I like you more than I can say."

At this moment, I wanted nothing more than to rub her into my own body, to possess her and have her regardless of the consequences.

Perhaps I was born with the seeds of incest in my bones. For Mom, Lin Xi, Maternal Aunt... these women related to me by blood, I harbored a desire that could never be extinguished.

Even if a bottomless abyss lay ahead, I would step into it without hesitation.

My large hand slid under her nightdress, moving gently along ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her thigh. The skin of a sixteen-year-old girl was so tender it felt like it could burst with water.

Her thighs shifted restlessly, and she inadvertently clamped down on my hand.

"Mnh..." She suddenly let out a soft moan. She cupped my chin with both hands and said softly, "Brother, I... I like you so much too."

I looked into her peach blossom eyes; they were like two pools of spring water, misty and damp. She was looking back at me with the same intensity.

Our gazes met and fused in the air. In that moment, the entire world seemed to consist of only the two of us.

I don't know who moved first, but we pulled each other close and kissed passionately.

My tongue slid into her mouth, easily finding her sweet little tongue. It was smooth and delicate, and her mouth tasted faintly of sweet toothpaste.

With a gentle lick, the tip of her tongue trembled and darted away like a startled little fish.

However, a second later, she actively met me. Our tongues became tightly entangled, chasing and playing with one another.

Her kiss was green and innocent, and that innocence drove me wild. My remaining sanity was like a small boat in a storm, smashed to pieces by the giant waves.

With a slight flick, I hooked and toyed with her tongue, and before long, I had drawn it into my own mouth. In this state, it almost looked like she was the one actively soliciting the kiss.

My kissing technique was seasoned, and she clearly couldn't keep up. Before long, she was panting for breath, letting out constant soft moans.

Her whimpering moans acted like a potent aphrodisiac, making my cock as hard as steel.

I rolled over, letting her straddle my abdomen. With one hand around her slender waist and the other supporting the back of her neck, I lightly scraped her mouth with my tongue. Her sweet saliva flowed along my tongue into my mouth, and I swallowed it down.

"Brother..."

Her face was flushed from the kiss. She gave my shoulders a few gentle shoves before I finally released her pink, tender mouth, ending that deep, lingering kiss.

A long silver thread of saliva hung between our mouths, acting like a bridge of love, constructing a channel for our incest.

The silver thread dripped from the corner of her mouth onto my chest. The scene was incredibly lewd.

"Brother..." she called out softly again, her body going limp as she collapsed onto me, her face pressed tightly against my chest.

"What is it?" I kissed her forehead gently. My hands involuntarily slid under her nightdress, grabbing her two soft, tight butt cheeks and slowly kneading them.

"Brother, I'm so scared..." Her expression was very tense, and her peach blossom eyes were filled with a deep, bottomless confusion.

Seeing her like this reminded me of when I was fourteen, the first time I had sex with my Maternal Aunt.

I had been pinning her white, voluptuous body down, thrusting my hips like my life depended on it, crashing into her pussy while my heart was simultaneously terrified. I had been filled with the thrill and the guilt of incest.

I shifted her body upward a bit and gave her red lips a light, fleeting kiss. "Don't be afraid. I'm here."

I was the one who had lured her into this abyss of incest. All the fault lay with me.

If incest was a sin, let me bear it all for her.

Call me worse than a beast if you want; regardless, I would never regret it.

Her butt was firm and elastic, and I couldn't bear to stop kneading it. My fingers slid down slightly, flicking against her hidden flower valley. My fingertips were immediately stained with a crystalline liquid.

I rubbed my fingers together; they were slick and wet.

I was surprised. Just from kissing, she had already leaked so much pussy juice? Was she really this sensitive?

"Brother, don't..."

Her body tensed, and she gave me a pleading look.

I forced myself to resist the urge to pull her panties aside. Instead, I hiked her nightdress up to her waist, exposing her perky, enticing ass to the air. My hands engaged in another round of lewd kneading, molding her small butt into various shapes. I glanced to the side; her skin was so white that even in the dark, her two high, perky cheeks reflected a crystalline light, like two glowing steamed buns. I loved them.

My lower body was so hard it was painful. As a form of protest, I gave her pussy a hard thrust.

She hadn't expected a surprise attack and immediately let out an irrepressible cry.

"What are you doing?" She hammered my shoulder with her fist in shy indignation.

"How does it feel?" I whispered into her ear, blowing hot air. I loved this look of hers—half-shame, half-anger.

She gave a soft hum and refused to answer. Sensing my fingers beginning to probe the edge of her panties, she quickly said, "It's tingly and numb... it feels very... very good."

"Do you want more?"

She was lying on top of me, and my cock was pressed right between her butt cheeks.

"Brother..." she pleaded softly. "Can we go slow, please?"

"Okay." I nipped her earlobe. "Even if you offered it to me, I wouldn't take you right now."

She let out a sigh of relief. The next moment, she actually lowered her head to kiss me, her sweet tongue boldly licking my lips.

I was stunned. How had this girl become so proactive?

"Brother, I've never even been in a relationship," she whispered in my ear. "Let's take it slow and date. Let me taste what love feels like, and then I'll give myself to you, okay?"

I pretended to be hurt. "Don't you like me?"

"I do." Fearing I would overthink it, she kissed me again. "But liking someone and being in a relationship aren't the same thing."

"Then let's have a brother-sister romance."

I responded passionately to her kiss. Our tongues were like two little snakes, entangling for a long, long time.

Finally, she gave the tip of my tongue a playful nip and corrected me, "It's an older sister-younger brother romance, okay? Don't you know that with twins, the one born first is the younger one?"

"Fine, I'll let you be the older sister for tonight."

As I responded, I pushed her nightdress up from her waist to above her breasts, revealing her graceful body. "As the older sister, shouldn't you give your little brother some benefits?"

"What kind of benefits do you want?" After a moment of hesitation, she cooperated as I pulled the nightdress off.

By the orange lamplight, I admired the girl beneath me. Willow waist, long legs, full breasts, and a peach-like ass. She was wearing nothing but a thin bra and panties soaked with pussy juice. She was a fatal temptation.

I took a heavy breath, then took her slender hand and placed it on my cock.

The moment her small hand touched the glans, the cool, moist sensation made me let out a groan.

She jerked her hand back as if she'd been electrocuted, her face turning bright red.

I pulled her hand back again. "Have you ever seen a man's... this?"

She shook her head gently.

"But you've seen porn videos, right?" I guided her hand, letting her soft palm wrap around the head of my cock.

This time she ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠didn't let go. She held it loosely, though her posture was stiff.

"I've seen them..."

She stole a quick glance at my crotch and then immediately looked away. However, she couldn't hold out for more than three or four seconds before her eyes drifted back. Seeing her act like a thief with a guilty conscience was quite amusing.

"If you want to look, get closer."

I knelt upright on the bed, my penis standing tall like an iron rod.

I pulled her toward me. "When I didn't know anything, I was very curious about a woman's body too."

That gentle pull almost made her face collide with my cock. She turned her head away in embarrassment, her pink jade neck flushed with a rosy hue.

After about thirty seconds, driven by curiosity, her head finally turned back inch by inch.

At first, her gaze was flickering, but as time passed, the shame on her face faded, replaced by curiosity and a sense of inquiry. Her gaze became bolder.

In the end, her flirtatious peach blossom eyes were fixed on the cock standing before her; she seemed to have forgotten to even blink.

She even reached out her warm, soft hand to flick my cock back and forth, studying it intently for about seven or eight minutes.

"Have you seen enough?"

She had been staring at my cock like a curious baby for so long, and she actually seemed to be enjoying the view.

She looked up at me, gave a soft "Mnh," and then returned her gaze to my cock. She suddenly reached out a finger and gently tapped the eye of my penis.

I sucked in a breath of cold air as a wave of pleasure shot from my feet straight to my brain.

I looked down at her small, red mouth, suppressing the urge to shove the glans inside. I asked deliberately, "Does it look good?"

"It's so pretty. White and tender." She slid her finger along the shaft. "White with a hint of red, like a freshly peeled egg. It's much cuter than the ones in the videos."

I teased her, "I didn't realize you'd seen so many."

She looked a bit embarrassed. "Not that many. I just watched a few with Chen Xiao and the others. The guys in the videos have black, ugly things down there. It's gross."

She playfully pinched the head of my cock. "Brother, you're so hard. And so hot."

"The harder and hotter, the better."

"Brother, have you ever measured it?" She stared intently at my cock, even swallowing almost imperceptibly.

I touched the corner of her lip. "I've never measured it. Do you want to?"

Hearing this, she tentatively wrapped her hand around my cock. However, one hand couldn't even fit around it. She had to use both small hands, her long, slender fingers closing together. Her two white, delicate hands enveloped the glans, and the pleasure made me groan. I couldn't help but sway my hips, grinding against her palms.

Her arms moved with my rhythm, and her breathing became rapid. Her moist eyes watched without blinking as the massive glans moved back and forth in her hands. "Don't they say online that the average Chinese man is only eleven or twelve centimeters? Yours must be twice as big as everyone else's."

The friction in her small hands made me squint my eyes in bliss. "Your brother is what they call 'exceptionally gifted.'"

"Exceptionally gifted? Brother, I think you're a mutant."

"You're the mutant!" I tapped her head. "Everyone is different."

"What are you worrying about all day? You even know the average size of a man?"

She huffed in dissatisfaction. "I'm not a kid anymore. Of course I'd learn about sexual health. Besides, I'm sixteen. Who hasn't seen a few movies?"

"Lin Xi," I called out softly.

"Hmm? What?" She looked up, her eyes questioning.

"Is mine bigger, or the ones in the videos?" I couldn't help but feel a competitive urge.

"Yours is bigger."

She answered and buried her eyes back in her work. Her hands slid from the glans to the base, gripping the root of my cock tightly.

"Oh..." A wave of pleasure, the urge to cum, suddenly swept through my body like a flood. I groaned and grabbed her wrists, forcing her to stop the surging sensation.

"Does it really feel that good?" she asked, looking up at me with curiosity.

I looked down at her jade-like face, panting. Just a second more and I would have shot my cum all over her face.

"It feels so good I almost fainted."

I gently released her wrists. I had left a few red marks on her slender skin. "Does it hurt?"

I rubbed the red marks with my thumb, feeling a pang of regret. "Why didn't you say anything?"

"It only hurts a little. It's fine."

Her attention was entirely focused on my cock. She pulled her hand back dismissively, using one finger to prop up the glans and lift it slightly, while her other hand reached for my scrotum.

"What are you doing?"

I instinctively recoiled. The shadow of Maternal Aunt almost crushing my balls hadn't faded yet.

"I just want to see." She looked at me strangely. "What are you hiding for?"

I grabbed ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her other hand and made her hold my cock again, swaying my hips. "There's nothing to see there. Just look at the thing in your hand."

"Don't move!" She gave my cock a light pinch, scolding me gently. "Can't I just look? It's not like I'm going to eat you."

She held my cock with one hand so I couldn't move, while her other hand cradled my scrotum, turning it over to inspect it.

Her face was very, very close. She looked for about three or four minutes before finally lifting her head from my crotch.

Her delicate hand played with my testicles, and she giggled. "They're like two peeled boiled eggs. They feel so soft and smooth."

I panted, "Do you ever get tired of looking?"

She acted spoiled. "Isn't this my first time seeing one? Can't I be a little curious?"

"Fine, fine, fine."

She looked up, seeing my face was flushed red. "Brother, are you in a lot of pain?"

"What do you think?" Her hands were rubbing my cock, and while it was soft and felt good, it wasn't nearly enough.

In fact, her teasing was making it harder to bear.

"Then what should we do?"

"You're the one who caused this. Shouldn't you fix it?"

"But... I don't know how..." Her expression was troubled. Her two delicate hands gripped my cock and gave it a few experimental tugs up and down. Her eyes were shy. "Is this okay?"

"Not really." I was breathing hard. Her graceful, nearly naked body was a lethal aphrodisiac.

"Then what..." When she got shy, her voice became high-pitched and sweet, making my heart melt.

"Lie down."

I pushed her back onto the bed and leaned over her.

"What are you doing now?" She was very nervous, her small hands gripping the bedsheets on either side of her waist.

I stroked her face. "If I don't let this fire out today, your brother is going to die from holding it in."

She didn't speak, just watched me nervously.

I spread her long legs slightly and realized the black lace panties she had just put on were already soaked with honey. Even her thighs and her little butt were wet.

I reached down and gave her pussy a light stroke, my hand coming away covered in spring water.

The moment my palm touched her pussy, she let out a short moan. Her white thighs twitched, and the wet patch on her panties deepened. Seeing her so sensitive drove me to the brink.

I ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠immediately thrust my cock between her legs. The thick shaft, separated only by a thin layer of lace, pressed tightly against her tender pussy.

"Brother..."

Feeling the burning organ at her entrance, she called out to me, her peach blossom eyes misty. "It's so hot..."

"Baby, squeeze your legs tight."

As I instructed her, I pulled her two slender, straight legs together.

She bit her lower lip and obediently squeezed her legs shut.

"Oh..." I couldn't help but groan. The soft flesh of her inner thighs and her tender mons pubis formed a soft, incredibly tight "meat pussy" that enveloped my cock. The sensation was intoxicating.

I gritted my teeth and thrust my hips forward. My thick cock slid through the gap between her legs until my crotch was pressed against her butt, and the massive glans broke through, pressing against her flat belly.

I looked down at her. Her current posture was incredibly erotic. She was lying on her back, her two jade-like legs pressed together and raised toward the ceiling, held tightly in my arms. Her small feet were crossed over one of my shoulders.

I was kneeling on the bed, holding her legs, leaning forward as my thick cock inserted into her butt crack and emerged over her belly, traversing the entire length of her leg gap.

The glans, larger than a duck egg, was stained with her spring water. It was shiny, fierce, and menacing, with the eye open and pointing directly at her flat stomach.

"Brother..." She let out a moan, her waist twisting slightly. Her face was flushed a seductive red. "It feels so strange down there..."

"Don't worry, Brother will help you..."

I turned my head to kiss one of her feet resting on my shoulder, then began to slowly swing my hips.

The soaked panties were as thin as nothing and offered no resistance. My cock and her pussy were practically pressed together skin-to-skin. I could clearly feel how soft her mons was and how tender her opening felt.

As the shaft rubbed over her pussy, the indescribable pleasure made my whole body tremble.

This was my sister. My biological sister.

At this moment, the two of us were clinging to each other, grinding our genitals together without any bottom line or shame.

She was even worse off under the friction. Her small hands, which had been gripping the sheets, were now covering her face. Her white, delicate body shivered with every thrust and rub.

The speed of my hips increased. My pelvis slammed into her white, round butt over and over, creating a crisp "clap, clap, clap" sound that echoed through the bedroom.

"Oh... oh... oh... ohhh..."

Her full body shook from the impact. She couldn't hold back her moans, letting out one sweet, cloying cry after another.

It was summer, and the AC wasn't on. Before long, both of us were covered in a thin layer of sweat, making our bodies slick.

I held her slippery thighs and focused on the grunt work of her "meat pussy."

The feeling of my cock being enveloped by her mons and thighs was no different from actual fucking.

Perhaps because it was my sister beneath me, the stimulation was incredibly intense. My thrusts became more ferocious, the long cock rubbing and traversing her honeyed gap again and again. The massive glans poked in and out against her flat, smooth belly. The scene was provocative and lewd, making my blood boil.

The spring water from her pussy flowed out in wave after wave, and pussy juice splashed with every thrust.

"Good sister, does it feel good?" I whispered.

"Fe... feels good... ohh... mnh..."

She answered with difficulty between moans. Her fingers spread slightly, and her seductive peach blossom eyes peeked at me through the gaps.

The moment our gazes met, she shyly closed her fingers again, but my brain felt like it exploded. My entire body went numb.

Those seductive eyes brought a sense of depravity and taboo I had never felt before, setting my lust ablaze.

I began to fuck her leg-pussy like a madman. My body rose and fell, and the "clap, clap, clap" sound filled the room.

If the room hadn't been well-soundproofed, I would have been worried about attracting Mom's attention.

"Mnh... mnh-mnh..."

She covered her mouth tightly, trying to suppress her moans, but a few cries still escaped her throat under my fierce thrusting.

Seeing her unable to withstand the lashing, I fucked even harder. My cock slammed into her leg gap again and again, rubbing wantonly against her pussy.

She eventually gave up trying to cover her mouth and opened her lips, letting out one cheerful, cat-like moan after another.

Her two long legs, which had been squeezed tight, were eventually knocked apart by my force. They now rested on either side of my waist, swaying back and forth with every thrust.

Without the tightness of the leg gap, the pleasure began to recede like a tide. Panting, I continued to rub my cock against her flower valley, making her pussy leak incessantly.

She moaned continuously in bliss, but I was feeling more and more frustrated. I simply lay down and pulled her into a side-lying position. I guided my cock back into her butt crack and continued to fuck her from the side. The soul-stirring sensation of being tightly enveloped by her legs again made me let out a low growl. Holding her butt with one hand, I thrust dozens more times. Finally, with a desperate lunge of my hips, the glans buried itself deep in the leg gap, my belly pressed tight against her butt, and I cummed long and hard.

She curled up in my arms like a kitten, her whole body trembling.

The two of us reached our orgasm together while grinding our genitals.

In an instant, I felt her wet leg gap become a sticky mess.

I held her in that side-entry position for a long time as we rested. Eventually, I pulled my softening cock out from her butt crack.

It was shiny and stained with streaks of white cum.

She looked a bit of a mess in my arms. Her soaked panties were covered in my cum, and there was white discharge on her thighs and belly as well.

"Brother..." she called out softly.

Her face was like a peach blossom, her eyes soft and seductive. She was at her most beautiful.

She panted for a moment, then sat up with difficulty. She reached out a finger to scrape some of the thick cum from her panties and held it up to inspect it.

After watching it for a few minutes, she wiped the cum onto her thigh. "I need to go wash up."

I found her slippers and put them on her small feet. "Do you want me to help you wash?"

She gave me a gentle push, her eyes full of lingering lust. "No. If I let you help, who knows how you'll bully me."

"Fine, wash yourself then."

I gave her beautiful ass a light slap.

Her two white, plump cheeks were red from my pounding. With the slap, the elastic flesh trembled, a sight that stirred the heart. She rolled her eyes at me and walked into the bathroom with her long legs.

We shared a bathroom, and both our bedrooms connected to it. It was the third passage between our rooms, besides the living room and the balcony.

As I gathered the soaked sheets, I realized the mattress pad underneath was also wet.

Once I had tidied the bed, the bathroom door opened softly, and she walked out. Her body was graceful and white, still dotted with crystalline water droplets.

"You should go wash too," she said, tossing her long hair back.

"Okay."

My eyes lingered on her thin, petite silk panties. "I haven't seen you wear those before."

She rolled her eyes at me. "You pervert. What are you looking at all day? Your sister's panties?"

"You were wandering around in front of me all summer like you were wearing a bikini. I couldn't help but notice."

"Get out of here. I just bought these a few days ago. The fabric is soft and comfortable."

She sat on the edge of the bed, applying some brand of body lotion to her thighs.

"How many pairs is this today?" I hooked the edge of her panties.

"Including the ones from this morning, this is the fourth pair." She looked at me with a hint of resentment, as if saying it was all my fault.

"I'll buy you some new ones later."

I turned and went into the bathroom. The pussy juice on my crotch was starting to dry.

In the laundry basket, I indeed found three more pairs of her panties: one white cotton pair and two black lace ones.

The two black lace pairs were soaking wet, saturated with her pussy juice. One of them must have been the pair she just took off, as it was covered in my thick, white cum.

I washed her three pairs of panties and took a hot shower. Looking around, I couldn't find my towel.

"Where's my towel?"

I scratched my head, clearly remembering I had thrown it in here after putting on my robe earlier.

Unable to find it, I walked out naked.

Seeing me completely exposed, she glanced at my waist and abdomen and let out a soft cry. "You pervert, why aren't you wearing anything?"

"I couldn't find my towel."

I walked naked to the balcony to hang her panties on the drying rack.

Watching me spread out her thin panties one by one to dry, she sheepishly stuck out her tongue. "I saw your towel there after my shower and just used it. Then I forgot it in my room."

"And you have the nerve to call me out for not wearing underwear? It's your fault."

I tapped her forehead and found another towel to dry myself.

After drying off, I saw she was still sitting cross-legged on the bed with no intention of leaving. I couldn't help but pinch her small ear. "You're still not leaving? Are you planning to sleep here tonight?"

She nodded as if it were the most natural thing in the world. "Yeah."

As she spoke, she flicked my semi-erect cock with her finger. "Why is it still standing up?"

"It'll go down in a bit." I found a pair of panties and put them on. "Aren't you afraid Mom will find you here?"

"What's there to be afraid of?" She let out a yawn. "I'll just go back tomorrow morning."

It seemed that since puberty, we hadn't slept in the same bed.

Faced with her initiative, I was more than happy to comply.

"Then let's get to sleep." I looked at the wall clock; it was already past midnight.

She lay down close to me. "Brother, you're not allowed to keep doing bad things."

I glanced over my sister’s petite, curvaceous body, and a moderate surge of desire stirred within me once more.

However, knowing we had already pushed things far enough for one night, I forced myself to suppress the heat in my chest. I gently wrapped my arm around her slender waist. "Whether I behave or not depends on how you act."

She didn't say anything else. We lay on our sides, facing each other, and drifted toward sleep in each other's arms.

Once the fire of lust had cooled, a rare sense of peace settled over me despite the feel of her smooth, soft waist in my hands. My sister, however, seemed restless. She tossed and turned in my arms, her pert little bottom rubbing against my waist. After about three or four minutes, she suddenly threw off the silk duvet and sat up.

"What is it?"

I asked, rubbing my bleary eyes as I stared at the delicate, snow-white curve of her back, confused.

"It's a little hot."

After turning on the air conditioning, she climbed back into my arms.

"Go to sleep," I murmured groggily. "Don't you have plans with Chen Xiao and the others tomorrow?"

"Don't even talk about that boy-crazy traitor," she huffed. "Chen Xiao suddenly said she's going on a date with her boyfriend tomorrow, so she can't make it."

A heavy wave of exhaustion washed over me. I didn't reply, only offering a noncommittal grunt.

But my sister was just getting started. She patted my cheek to keep me awake. "Hey, we were all in middle school together with Chen Xiao. Do you have any idea who her boyfriend is? This mysterious guy just appeared out of nowhere."

"No idea..."

I pulled her tight against me, pinning her arms and legs to stop her from squirming. "Go to sleep."

Perhaps it was because I’d spent the entire afternoon having sex with Teacher Chu Ning in her office, followed by nearly an hour of grinding against my sister’s pussy, but I felt utterly drained. Within minutes, I drifted into a deep sleep...
