I slammed the door behind me and shoved my sister against it, my hands already yanking her skirt up. "You want this cock breeding that tight cunt tonight?" I growled, fingers hooking into her panties and ripping them aside. Lena moaned, her 22-year-old body grinding against me, her tits heaving under her thin top. She was dripping already, her pussy lips slick and swollen, begging to be filled.
"Yeah, big brother," she panted, reaching down to squeeze my thick shaft through my jeans. "Fuck me raw and pump me full. I want your cum deep in my womb until it takes."
I didn't waste time. I spun her around, bent her over the kitchen table, and freed my hard dick. It slapped against her ass, heavy and leaking. I rubbed the head up and down her slit, coating it in her juices, then thrust in balls-deep in one stroke. Lena cried out, her walls clenching around me like a vice. I fucked her hard and fast, the table scraping the floor with every slam of my hips. Her ass rippled, her moans turning into filthy begging.
"Harder, fill me up, breed your little sister," she gasped. I grabbed her hair, pulled her head back, and pounded deeper, my balls slapping her clit. Every thrust pushed her forward, her nipples scraping the wood. I could feel her getting wetter, her cunt sucking me in, ready for what was coming.
I didn't pull out. I buried myself to the hilt and unloaded, thick ropes of cum flooding her unprotected pussy. She came with me, shaking and milking every drop as I stayed locked inside her, making sure it all stayed where it belonged. When I finally pulled back, my load leaked down her thighs, but I scooped it up and pushed it back in with two fingers. "Keep it in there. We're not done."
Lena turned, eyes glassy with lust, and dropped to her knees. She sucked me clean, tongue swirling over the head, tasting our mixed mess. "More," she demanded, voice hoarse. "I want you to knock me up proper."
We moved to the bedroom. I stripped her the rest of the way and laid her on her back, legs spread wide. Her pussy was pink and puffy, cum still oozing out. I climbed between her thighs and slid back in, slower this time but just as deep. I pinned her wrists above her head and fucked her with long, grinding strokes, my pubic bone rubbing her clit on every downstroke.
"Tell me you want my baby," I ordered, voice low and dirty.
"I want your baby, brother. Breed me. Fill my womb until I'm swollen with your kid." Her words pushed me over. I came again, flooding her even fuller, my cock pulsing as I ground against her cervix. She wrapped her legs around me, holding me in place so nothing escaped.
We didn't stop there. I took her again in the shower, bent over the sink, then on the floor with her riding me reverse cowgirl so I could watch my cock disappear into her cum-filled hole. Each time I emptied my balls straight into her, no barriers, no pulling out. By morning her belly had a slight swell from how much seed I'd pumped into her, and she kept her hand pressed there, smiling like she could already feel it taking root.
Lena looked up at me, legs still spread, my cum dripping from her well-used cunt. "Again?" she asked, voice raw.
I was already hard. I rolled her onto her stomach, mounted her from behind, and drove in once more, breeding her deep and rough until she screamed my name and took another load. This was ours now—raw, filthy, and exactly what we both needed. No going back.
