We had been circling each other for months. My sister Rachel was twenty-two, same as me, and after our parents left for their month-long cruise we had the house to ourselves. The first night alone she walked out of the shower in nothing but a towel that barely covered her ass. I stared. She noticed. Neither of us looked away.
Stop acting like you dont want to fuck me, she said, dropping the towel right there in the hallway. Her tits were full and heavy, nipples already hard. Her shaved pussy looked slick. Ive heard you jerking off at night saying my name.
I didnt deny it. My cock was already pushing against my shorts. I yanked them down and let it slap up against my stomach. Then come here and do something about it.
She crossed the hall in two steps, dropped to her knees, and took my dick straight into her throat. No teasing, no warm-up. She gagged on it, spit running down my balls while she sucked like shed been waiting years. I grabbed her hair and fucked her face, watching my cock disappear between her lips again and again.
Bedroom, I growled after a minute. She stood up, wiped her mouth, and walked ahead of me, ass swaying. I followed her, already planning how I was going to wreck her.
She climbed onto her bed on all fours and reached back to spread her cheeks. Fuck my pussy first. Get it sloppy before you take my ass.
I climbed up behind her and slammed in to the hilt in one thrust. She was dripping wet and tight as hell. We both groaned loud. I started pounding her right away, hips slapping against her ass, balls swinging. The wet sound of my cock driving into her filled the room. She pushed back into every thrust, moaning Harder, fuck your sister harder.
I reached under her and rubbed her clit while I fucked her. She came fast, cunt clenching around me, juices running down my shaft. I didnt stop. I kept drilling her until her arms gave out and she was face down, ass up, taking every inch.
When I pulled out she flipped over and spread her legs wide. Now my ass. Use the lube on the nightstand.
I slicked my cock and pressed the head against her tight hole. She relaxed and let me sink in slow, inch by inch, until my balls rested against her. Once I was buried I started thrusting. She hissed at the stretch but kept telling me not to stop. Fill your sisters ass. Make it gape.
I fucked her ass with long, deep strokes, watching her hole stretch around my shaft. She played with her clit the whole time and came again, ass squeezing me so hard I almost lost it. I pulled out, flipped her onto her stomach, and drove back into her pussy from behind. We switched holes every few minutes, her begging for whichever one felt dirtier at the moment.
Eventually I had her on her back with her legs over my shoulders, cock buried in her ass again. I leaned down and kissed her hard, tongues messy, while I pounded her. She reached between us and jerked her clit until she came so violently her whole body shook. That pushed me over. I buried myself to the root and unloaded, pumping thick ropes of cum deep in her ass.
We didnt stop there. Over the next three weeks we fucked everywhere: on the kitchen counter while dinner burned, in the shower until the hot water ran out, on the living-room floor with her riding me reverse cowgirl so I could watch her ass bounce. Shed wake me up by sitting on my face or sliding my morning wood into her pussy without a word. Id bend her over the dryer while it ran, or pin her against the fridge and fuck her standing up until she squirted down my legs.
One afternoon she came into my room wearing nothing but one of my old T-shirts and climbed onto my lap.
Tell me how nasty we are while you fuck me, she said, sinking down on my cock.
Youre my slut sister who cant get enough of her brothers dick, I told her, gripping her hips and bouncing her. You let me cum in your ass, your pussy, down your throat. Youre addicted to it.
She moaned and rode me faster. I am. I want you to breed me. I want you to knock your own sister up.
That fantasy made us both crazy. I flipped her onto her back and fucked her deep and steady, telling her exactly how I was going to fill her womb while she clawed at my back. She came twice before I pumped another load into her, grinding against her cervix as I emptied.
By the time our parents were due home we had fucked in every room, tried every position we could think of, and left cum stains on half the furniture. The night before they returned she came to my bed again, already naked and wet.
One more time, she whispered, straddling me. Make it count.
I slid into her and we moved slow and deep, staring at each other while we came together. She stayed on top afterward, my softening cock still inside her, both of us breathing hard.
Were not stopping just because theyre back, she said. Well find ways.
I nodded, already thinking about the next time Id bend her over somewhere quiet and fuck her raw again. The house felt different now. We werent just brother and sister anymore. We were each others favorite dirty secret, and we had no intention of giving that up.
