I never planned to fuck my sister. It just happened one sticky summer night when our parents were out of town. Jenna was nineteen, home from college, and I was twenty-one, stuck working a shit job. We’d always been close, but that closeness turned filthy fast.
We were drinking cheap beer on the couch, watching some dumb movie. Jenna wore these tiny shorts that rode up her ass every time she shifted. Her tits pushed against a thin tank top, nipples hard from the AC. I couldn’t stop staring. She caught me and smirked.
“Like what you see, big brother?” she asked, voice low and teasing.
I should have laughed it off. Instead I said, “Yeah. A lot.”
She didn’t pull away when I leaned in. Our mouths crashed together, tongues sliding hot and wet. She tasted like beer and cherry lip gloss. My hands grabbed her tits right away, squeezing hard through the fabric. She moaned into my mouth and climbed onto my lap, grinding her pussy against my cock through our clothes.
“Been wanting this forever,” she whispered. “Don’t stop.”
I yanked her tank top down and sucked her nipples, biting just enough to make her gasp. Her shorts came off next. No panties. Her cunt was shaved smooth and already dripping. I shoved two fingers inside her, pumping hard while my thumb rubbed her clit. She was tight, hot, and soaked.
“Fuck, yes,” she groaned. “Finger that pussy.”
I pulled my cock out. It was thick and throbbing. She wrapped her hand around it and stroked fast, then dropped to her knees. Her mouth swallowed me whole, lips stretching around the head, tongue swirling. She sucked like she’d been practicing, taking me deep until I hit her throat. Spit ran down my balls while she gagged and moaned.
I didn’t last long in her mouth. I hauled her up, bent her over the couch, and slammed inside her from behind. Her cunt gripped me like a fist. I fucked her hard, hips slapping her ass, balls swinging. She pushed back, begging for more.
“Harder, brother. Wreck that pussy.”
I grabbed her hair and pounded her. Every thrust made wet sounds fill the room. Her juices coated my cock and ran down her thighs. I reached around and rubbed her clit until she came, screaming and clenching around me. I followed right after, shooting thick ropes of cum deep inside her.
We didn’t stop there. We fucked on the kitchen table next, her legs over my shoulders while I drilled her. Then in the shower, her bent forward against the tiles. By morning we’d lost count. Cum leaked out of her every time she moved. She tasted herself on my cock and smiled.
After that weekend it became regular. Whenever we got the house alone, we went at it raw. No condoms, no pulling out. She’d ride me on the living room floor, tits bouncing, telling me how good her brother’s cock felt. I’d bend her over the dryer in the laundry room and pound her until she squirted. We talked dirty the whole time.
“Tell me how much you love fucking your sister,” she’d demand.
“I love stretching this tight cunt,” I’d answer, slamming in deeper.
Sometimes she’d wake me up with her mouth already on my dick, sucking slow and nasty until I flooded her throat. Other nights she’d sneak into my room wearing nothing but one of my shirts and climb on top, sinking down on my cock while our parents slept down the hall. The risk made it hotter.
We tried everything. I ate her pussy for hours until her legs shook. She let me fuck her ass one night after lots of lube and fingers, moaning like a whore while I stretched her tight hole. We watched porn together and copied the positions, laughing and groaning at the same time.
It stayed our secret. No one else knew how we spent those long weekends. She’d text me from college sometimes, sending pictures of her fingers buried in her cunt with captions like “Missing my brother’s cock.” I’d jerk off to them and send back videos of me stroking until I came.
The last time we fucked before she moved out, we did it in the backyard at night. She got on all fours on a blanket and I took her doggy style under the stars, pulling her hair and slapping her ass while I filled her up one more time. She came so hard she nearly blacked out.
We both knew it couldn’t last forever, but neither of us wanted to stop. Those raw, dirty sessions were the best sex either of us ever had. Just two adults who happened to be siblings, using each other’s bodies however we wanted. No guilt, no limits, just pure filthy pleasure whenever we could get it.
