My sister is several years older than me. She stands 170cm tall with breasts as large and heavy as pomelos, weighing about 54kg. She possesses long, slender limbs and a beautiful oval face that bears a striking resemblance to a famous starlet.

Ever since the day I was born, the doctor had taken the liberty of performing a circumcision. By the time I reached my second year of middle school, my physique was already quite robust; my manhood measured nearly 15cm, and my height had reached almost 170cm, nearly matching my sister's. However, because of my baby face, my family didn't pay much attention to my burgeoning masculinity. When we traveled, they would often let me share a bed with her. At school, hearing my classmates whisper about romance and passion, combined with the occasional late-night glimpses of locked premium channels at home, had left me intensely curious about the female form.

At home, my sister preferred comfort above all else. She usually wore nothing but a thin-strapped chemise that plunged deeply to reveal her cleavage. The hemline was short, barely covering her hips, as she moved about the house. Whether she was walking through the rooms or lounging on the sofa, her lithe, graceful silhouette and her snowy, smooth, tender skin were always on display. Her soft, slender waist and long, straight legs constantly ignited fantasies in my mind.

She favored light-colored chemises, but the fabric was so fine that it became nearly translucent under the light. Her full breasts strained against the material, making the delicate, rosy peaks of her nipples clearly visible. Occasionally, she would sip on red or plum wine; the slight intoxication would flush her beautiful face with a healthy, rosy glow, making her look breathtakingly radiant. With her lips moistened by wine and her eyes slightly heavy from the alcohol, she exuded a seductive charm that often sent me into a frenzy of solo play, fueled by my vivid imaginations.

Since our last trip, my sister seemed to have become even more enchanting. What used to be mere fantasy had now become reality. At home, she would wander around in nothing but a thin chemise, making it incredibly easy for me to touch her. Unless our parents were home, she rarely wore even a pair of panties. Since our family runs a 24-hour convenience store, our parents usually returned very late, leaving just the two of us—two young beasts drowning in a sea of desire.

I loved to stroke her slender, porcelain ankles while watching television. She liked to lie on her side on the sofa with her legs curled up. Sitting beside her, I would reach out to play with her ankles, my fingers tracing the delicate curves of her legs. My slow, deliberate movements often caused her soft legs to twitch and bend involuntarily.

I grew even more daring, meticulously playing with her exquisite feet, teasing her small, rounded toes. I would use my tongue to lick them one by one, sucking on them greedily until she would let out an involuntary moan, her other pale foot brushing against my face in response.

She loved the sensation of my tongue—the meticulous licking and sucking of her delicate feet. The tingling pleasure often trapped her in a web of desire, causing her to迎合 my advances and endure wave after wave of teasing from my tongue and fingers, sinking deep into a world of pure sensory bliss.

Sometimes, mimicking the scenes from Japanese films, I would use my tongue to lick and suck every inch of her skin, my fingers caressing her pale body. Beyond just licking and sucking her honeyed core, I even ventured to use my tongue to explore her anus. This would leave her gasping for breath, her puckered entrance opening and closing in frantic excitement.

After being teased a few times, she could no longer bear it. She would beg me to use my fingers to probe her. She whispered that the sensation of my tongue inside her was so tingly and delicious, yet it left her feeling an itchy, desperate need to be filled.

One afternoon, while watching TV, the teasing began again. I licked my way from her exquisite feet to her slender ankles, then followed the length of her long legs toward her sweet nectar. Her core was already drenched, waiting for my invasion. Unable to help herself, she began to rub her full, white breasts through her T-shirt, letting out a continuous stream of seductive moans.

Ignoring her gasps and the enticing writhing of her body, I continued my assault. I dipped my fingers into her nectar and began to gently probe the area around her beautiful anus. She let out a loud moan and cried out, "Oh... good brother, dear brother, hurry and fuck me! I want it so much... ah!"

I instructed her to bend over the sofa, arching her rear high in the air. I used my hands to spread her buttocks wide, pressing my tongue into her anus to lick her deep inside. Her hips moved in rhythm with my tongue, her voice pleading, "Stop licking! Just fuck me, sister can't take it anymore!"

Seizing the moment, I thrust my index finger firmly into her anus, pushing all the way in. The sudden intrusion startled her, and she cried out, "Ah... it hurts a little... but it's so tingly... ah... I can't stand it!"

Her moans drove me wild with desire. I gazed intently at her perky, rounded buttocks—so full, so elastic, the skin so smooth and fine. The more I thought about it, the faster my hand moved, and the more wanton her cries became. Her hips began to sway and twist proactively, meeting the rhythm of my finger.

Suddenly, a curious thought struck me: would her rear smell? I pulled my hand out to check, but it was quite clean.

She turned her head back, moaning, "Oh... don't stop, it feels so good!"

I didn't hold back then, pushing both my index and middle fingers inside. It was difficult at first, especially as the knuckles passed through the tight entrance. Once the knuckles were in, the sensation of tightness was overwhelming. She let out a pained cry, telling me to slow down, but eventually, her muscles began to relax.

I began to pump my fingers in and out, savoring the incredible tightness of her entrance and the sound of her wanton cries: "Ah... gently... it's both painful and tingly... ah!"

While playing with her rear, I would massage her breasts, and sometimes use my pinky finger to tease her wet core at the same time.

We played like this for about thirty minutes. Her body tensed and relaxed twice more before she finally slumped onto the sofa, limp and completely at my mercy.

Unable to wait any longer, I pulled my fingers out. Her anus was now incredibly soft and moist. I propped her hips high and thrust my cock hard into her rear.

She let out a sharp cry, and I felt the initial intense pressure suddenly give way as my cock slid smoothly into her. It was even tighter than her vagina.

I began to thrust slowly, savoring the warmth of her rear. She seemed to have fully surrendered to the sensation, actively thrusting her hips back to meet me, her buttocks bumping against my testicles and thighs. She moaned incessantly, "Ah... ah... so good..." As she increased the speed of her swaying, I thrust even harder, watching my cock slide in and out of her smooth skin while my hand worked her clitoris and squeezed her bouncing breasts.

Gradually, she seemed to lose herself in a frenzy, her hips bucking wildly. Her long hair whipped around as she tossed her head in madness. Her moans grew higher and more piercing: "Oh... fuck me to death! Hurry, fuck your sister to death... oh!" I met her intensity with even more frantic, powerful thrusts.

Her cries reached a crescendo, echoing through the living room: "Oh... don't... don't stop... I can't take it anymore!"

Her hips never stopped twisting. Driven by excitement, I pulled her tightly against my chest from behind, thrusting deep and hard until finally, I erupted inside her. I collapsed onto the sofa, holding her limp body as we drifted there until darkness fell.

The next morning, she turned to me and complained, "You were so rough yesterday. My butt hurts so much, I almost couldn't even go to the bathroom today!"
