The house was quiet except for the wet sounds of my sister's mouth sliding up and down my cock. She was on her knees in the living room, tits hanging out of her tank top, spit dripping down her chin onto the carpet while she gagged herself on my thick shaft. "Fuck, sis, take it deeper," I growled, grabbing her hair and pushing her head until her nose pressed against my stomach. She moaned around me, throat squeezing tight, eyes watering but never breaking contact.
We had been doing this for months. Mom and Dad were away on their anniversary trip, leaving us alone in the big empty house with nothing but years of pent-up family tension to burn off. It started with her catching me jerking off in the shower, then escalated to her climbing in naked and riding me right there under the spray. Now we fucked anywhere, anytime, as nasty as possible.
She pulled off my dick with a loud pop and looked up, lips swollen and shiny. "You gonna cum down my throat or you saving it for my cunt?" Her voice was pure filth, no teasing left. I hauled her up, spun her around, and bent her over the couch. Her shorts were already gone. I slammed into her soaked pussy in one thrust, balls slapping her clit. She screamed and pushed back, meeting every stroke.
"Harder, big brother. Wreck that hole." I gripped her hips and pounded, the couch scraping across the floor. Her tits swung under her, nipples brushing the fabric. I reached around and rubbed her swollen clit in rough circles until she came hard, pussy clamping down like a vice. Her juices ran down my balls. I didn't stop. I kept fucking through her orgasm, chasing my own.
When I was close I pulled out and shoved my cock straight into her ass. She yelped but pushed back harder. "Yes, fuck my ass, fill it up." I buried myself to the hilt and unloaded, pumping thick ropes of cum deep inside her. She reached back and spread her cheeks so I could watch it leak out around my shaft.
We weren't done. Later that night she crawled into my bed wearing nothing but one of Dad's old shirts.
She straddled me and sank down on my cock again, riding slow and deep while she whispered the dirtiest shit. "Remember when we were kids and you used to peek at me in the bathroom? I knew you wanted this. I used to finger myself thinking about you breeding me." I grabbed her ass and thrust up to meet her, our bodies slapping together.
She leaned down and we kissed messy and open-mouthed, swapping spit while she ground her clit against me. I flipped her onto her back and folded her legs to her chest, pounding her pussy until she squirted all over my stomach. Then I pulled out and fed my cock back into her mouth so she could taste herself mixed with my cum.
By morning we had fucked in every room. Kitchen counter, shower again, even bent over Mom's dresser while we looked at family photos. She came so hard she knocked one over. We didn't care. The taboo only made it hotter. When our parents came home we were sitting on the couch like nothing happened, but under the blanket her hand was wrapped around my cock, slowly stroking while we smiled and said how quiet the weekend had been.
We kept going after that. Every chance we got. Extreme, raw, no limits. Just two adults who happened to be related, fucking like the world was ending.
