I walked into the living room and saw my little sister bent over the couch in nothing but a tiny tank top. Her ass was up, pussy already glistening. I was twenty-two, she was nineteen, and we had been dancing around this for months. My cock was already hard and pushing against my shorts. I am a futa, and she knew it. She knew exactly what I had between my legs and what I wanted to do with it.
“Lock the door,” she said without turning around. “Mom’s gone all weekend.”
I kicked the door shut and stripped fast. My thick cock sprang free, heavy and veined, balls full and tight. I grabbed her hips and yanked her back against me. My cock slid between her ass cheeks and rubbed along her wet slit.
“You want this dick inside you?” I growled.
She pushed back, grinding her pussy on my shaft. “Fuck me. Breed me. I’m not on anything.”
That was all I needed. I lined up and shoved in hard. Her cunt was tight and hot, gripping every inch as I buried myself to the balls. She moaned loud and filthy. I started pounding right away, no slow build-up, just raw thrusts that made her ass ripple every time my hips slammed into her.
“Take it,” I grunted. “Take your sister’s cock. Gonna fill this pussy up until it leaks.”
She reached back and spread her cheeks wider so I could go deeper. “Yes, fuck, breed me. Put a baby in me. I want your cum.”
I fucked her like that for a long time, hard and steady, the wet sound of my cock driving into her cunt filling the room. Every thrust pushed her forward on the couch. Her juices ran down my balls. When I felt her start to tighten, I reached around and rubbed her clit fast.
She came hard, pussy spasming and milking my shaft. I didn’t stop. I kept driving through her orgasm, chasing my own. My balls slapped against her with every stroke. I leaned over her back and bit her shoulder.
“Gonna breed you full,” I said right in her ear. “Gonna pump so much cum in this cunt you’ll be pregnant by morning.”
I slammed in one last time and unloaded. Thick ropes of cum shot deep inside her, pulse after pulse. She pushed back against me, taking every drop. My cock twitched and kept spurting until it overflowed and started leaking out around my shaft.
I pulled out slow and watched my cum drip from her stretched hole. She stayed bent over, panting.
“Don’t move,” I told her. I was still hard. Futas stay ready. I pushed two fingers into her sloppy cunt and scooped some cum out, then rubbed it over her asshole. “I’m not done breeding you.”
She looked back at me, eyes glassy. “Then do it again. Fuck my ass or my pussy, just don’t stop until I’m knocked up.”
I shoved back into her pussy and started round two, slower but just as deep, grinding my cock against her cervix with every thrust. Cum squelched out around me.
I talked dirty the whole time, telling her how I was going to keep her full of my seed until her belly swelled. She came again, screaming my name, and I followed, flooding her a second time.
We moved to the bedroom after that. I fucked her on her back with her legs over my shoulders so I could watch my cock disappear into her. Then on her side, one leg lifted high while I pumped more cum into her already overflowing pussy. By the fourth load she was a mess, cum running down her thighs in thick white streaks, but she kept begging for more.
“Keep breeding me,” she whispered while I spooned her from behind and slowly thrust into her used cunt. “I want to feel it for days.”
I came one last time deep inside her, holding her tight while my balls emptied. We stayed locked together, my cock still twitching inside her flooded pussy. I reached around and rubbed her swollen clit until she came again, softer this time, her body shaking against mine.
She fell asleep with my cum still leaking out of her. I stayed awake a while longer, hand on her belly, thinking about how full I had made her and how I was going to do it again as soon as she woke up. The house was quiet except for her breathing. Outside it was dark. Inside, my little sister was thoroughly bred, just the way we both wanted.
