Fucking my adolescent yet mature sister was the best feeling of my life

Things from the same source go well together. The same is true for siblings. A brother's penis belongs in the vagina of his sister, specially if she is young.

Do you know why milk works so well as a beef tenderizer? Because it comes from the same source. What comes from the same blood, same flesh, same womb… fits together perfectly.

I learned this truth in the most beautiful and forbidden way through my little sister, Hania.

Three years away in another city had changed everything. I returned home with a prestigious high school degree, taller, broader, and no longer the same boy who left. My parents welcomed me warmly at the airport, but Hania was at home preparing for an exam.

When I finally stepped into our small, cozy house, nostalgia washed over me. Nothing had changed except her.

I entered our shared bedroom without knocking and froze.

Hania was completely naked.

My little sister had transformed. At sixteen, her body was no longer that of a child. Full, perky breasts with soft pink nipples, a tiny waist that flared into wide, feminine hips, and a smooth, hairless pussy that made my throat go dry. Her skin glowed with youthful beauty. Long black hair cascaded down her back. She had become breathtakingly beautiful.

“Sorry, Hani! I’ll wait outside,” I said quickly, closing the door, my heart hammering.

A minute later she called me in. She was now wearing tiny boxer shorts that barely covered her ass and a tight crop top that clung to her breasts. The moment I stepped closer, she hugged me.

Her soft, warm body pressed against mine. Her breasts squished against my chest. I could smell her sweet, feminine scent. My cock twitched instantly.

“You’ve grown so much, Hania…” I whispered, my hand gently stroking her back.

“So have you, brother,” she replied in her new soft, mature voice. “Your chest feels so strong now.”

She looked up at me with those big, innocent-yet-knowing eyes. The air between us already felt thick with something dangerous… and deliciously incestuous.

Later that evening, while the sun was setting, I went to take a bath. I stripped down and stepped under the warm water, my mind filled with the image of my naked little sister. My cock grew rock hard as I remembered every curve of her young body.

Then the bathroom door opened.

Hania walked in calmly and started undressing right in front of me. I could see her sensual silhouette through the shower curtain.

“H-Hania… what are you doing?” I asked, voice shaky.

She didn’t reply. She simply stepped into the shower with me, completely naked. Her beautiful teenage body was fully exposed perky breasts, smooth pussy, and those wide hips that screamed fertility.

“You’re my brother,” she said softly, stepping closer until her breasts brushed against my chest. “We used to bathe together all the time. Why are you acting so strange now?”

Water cascaded over both of us as she turned around and pressed her back against my front. Her soft, round ass nestled right against my throbbing cock. I tried to pull back, but she gently pushed herself backward until my hard, incestuous cock was trapped between her ass cheeks.

“Hania…” I groaned, my hands instinctively gripping her narrow waist.

She stayed quiet after that, breathing softly, calmly accepting everything.

I turned her around slowly. Hania looked up at me with calm, submissive eyes. There was no hesitation, no shyness just quiet acceptance, as if she had already decided long ago that this was natural.

I kissed her deeply. She parted her lips and let me explore her mouth, her tongue gently responding to mine. Her hands rested lightly on my chest, not pushing away, but holding on.

My hand slid down her wet body. I cupped one of her soft breasts, squeezing it gently, then rolled her nipple between my fingers. A tiny, almost silent breath escaped her lips. I moved lower, slipping my fingers between her thighs. Her pussy was incredibly warm and slick wetter than the shower water. I rubbed her swollen clit in slow circles. Hania’s thighs trembled slightly, but she stayed standing, quietly letting me touch her most private place.

I pushed one finger inside her tight virgin cunt. She was unbelievably snug. I added a second finger, slowly pumping them in and out while my thumb continued teasing her clit. Hania’s breathing grew heavier, but she remained mostly silent only soft, feminine sighs and occasional tiny whimpers escaped her.

She suddenly lowered herself to her knees on the wet shower floor. Without a word, she looked up at me with those calm eyes, opened her pretty mouth, and took the head of her big brother’s cock between her lips. She sucked me gently, lovingly, swirling her tongue around the tip while her small hand stroked the shaft. The sight of my little sister willingly sucking my cock was pure heaven.

After several minutes of her warm, wet mouth worshiping me, I pulled her back up. I lifted one of her legs, wrapping it around my waist, and pressed the thick head of my cock against her dripping entrance.

Hania looked into my eyes and gave the smallest nod her silent permission.

I pushed forward slowly. Her tight incestuous pussy stretched around me as I entered my own little sister for the first time. Inch by inch, I sank deeper into her velvet heat. She bit her lip and breathed shakily but never asked me to stop. When I finally bottomed out, my balls pressed against her, I held her close, savoring the forbidden feeling of being completely buried inside Hania.

I began to thrust,.long, slow, deep strokes. The sound of wet skin meeting wet skin mixed with the running water. I fucked her tenderly but passionately, grinding against her clit with every thrust. Hania’s arms wrapped around my neck. Her face was buried in my shoulder as she took every inch of her brother’s cock like a good little sister.

I picked up the pace, fucking her harder. Her perky breasts bounced with each thrust. I leaned down and sucked hard on her nipples, alternating between them while pounding deeper into her welcoming pussy.

“You feel so perfect, Hania… so tight for your brother,” I whispered hotly in her ear.

She didn’t reply with words, she just moaned softly and tightened her arms around me, pulling me even deeper.

I fucked her with long, powerful strokes, claiming my little sister completely. The pressure built higher and higher. Hania’s pussy started pulsing and squeezing around my cock. Her whole body trembled as she came silently her mouth open in a silent cry, eyes half-closed in pleasure.

The feeling of my little sister cumming on my cock pushed me over the edge. With a deep groan, I buried myself as deep as possible and exploded inside her. Thick, heavy ropes of cum flooded her young womb. I kept thrusting through my orgasm, pumping every drop of my seed into my own sister.

We stayed like that for a few minutes my cock still buried inside her, calm cascading over our joined bodies, her mouth staying still to my tongue kisses in submissive content. Out mouth's left finally with a saliva trail of sweetness, as suddenly our mother called us from downstairs for dinner.

"Well guess I have to pull out from you Hani", I said kissing her nose as we seperated and got off the bed. "Don't worry brother....I am here..... Tomorrow after my exam.....I will be free for quite some time...teach me all about sex during that time...... welcome back home brother", she said sweetly in her monotone voice.

"I am back my Hania"
