I slammed the door shut behind me, cock already rock hard from the party downstairs. The room was pitch black, just like she said it would be. "Get on the bed and spread," I growled, stripping fast. My hands found smooth thighs in the dark and I shoved them apart, burying my face between them.
She tasted sweet and wet, moaning low as I licked her clit hard and fast. "Fuck, you’re dripping," I muttered, tongue fucking her hole before sucking on her swollen nub. She bucked against my mouth, grabbing my hair and grinding.
I flipped her onto her stomach, yanked her hips up, and slammed my thick cock straight into her pussy in one thrust. She was tight as hell, gripping me like a vice. "Goddamn, sis—no, wait, fuck, you feel too good," I grunted, pounding her deep and rough. Her ass slapped back against me with every stroke. I reached under and rubbed her clit while I fucked her, feeling her walls squeeze and flutter.
She pushed back harder, panting dirty words I couldn’t quite catch. I pulled out, flipped her again, and drove back in missionary, her legs over my shoulders so I could bottom out. Sweat slicked our skin. I sucked on her nipples, biting just enough to make her yelp and clench around me. "Take that cock," I snarled, slamming faster. Her pussy was soaked, juices running down my balls.
We switched again—I had her riding me, her tits bouncing in the dark as she bounced on my dick. I grabbed her hips and thrust up to meet her, hitting her G-spot until she was shaking. Then I pulled her down, flipped us once more, and fucked her from behind doggy style, one hand fisting her hair while the other spanked her ass red. "You like getting railed like a slut?" I asked, voice hoarse. She moaned yes and pushed back for more.
I was close, balls tight, when I reached for the lamp. Light flooded the room. My cock was buried balls-deep in my stepsister Emily. Her eyes went wide, mouth open in shock, but her pussy kept pulsing around me. We froze for a second, both realizing the blind date mix-up had gone way too far. Then she rocked back on my dick anyway.
"Fuck it," she hissed. "Don’t stop."
I didn’t. I fucked her harder than before, raw and filthy, both of us chasing the orgasm we’d already started. She came first, screaming and soaking my cock, and I followed right after, pumping thick loads deep inside her. We collapsed, breathing hard, my cum leaking out around my softening dick.
We stared at each other, hearts pounding, knowing we’d crossed a line we could never uncross. But neither of us moved away.
