I woke up to the feel of a warm, wet mouth sliding down my cock. It was pitch black in the room, the middle of the night, and for a second I thought I was still dreaming. Then the tongue swirled around the head and a soft moan vibrated against my shaft. My hips bucked up on instinct, pushing deeper into that hot throat.
“Fuck, yeah,” I grunted, half asleep myself. My hand found a head of hair and I gripped it, guiding the rhythm. Whoever this was sucked like they were starving for it. Sloppy, noisy, taking me all the way until I felt the back of their throat squeeze around me.
I reached down and grabbed a handful of tit. Full, soft, heavy in my palm. The nipple was already stiff. I pinched it and the mouth moaned louder, sucking harder. My other hand slid lower, between spread thighs, and found a dripping pussy. Two fingers sank right in. Tight, slick, clenching around me like it wanted more.
“Jesus, you’re soaked,” I muttered, pumping my fingers in and out while the mouth kept working my dick. I could hear how wet it was, the filthy squelch every time I thrust my fingers deep. The hips rocked back against my hand, greedy.
I flipped us without thinking, rolling the body beneath me. My cock slapped against a soft belly as I shoved the legs apart and lined up. One hard push and I was buried balls-deep in that tight cunt. We both groaned at the same time. I started fucking hard and fast, the way I like it when I’m half asleep and horny as hell. Skin slapped loud in the dark. Every thrust made wet sounds echo off the walls.
The pussy was gripping me like a fist, milking every inch. I leaned down and sucked a nipple into my mouth, biting just hard enough to make the body jerk and clench around my cock. Hands grabbed my ass, pulling me deeper, nails digging in.
“Harder,” a voice panted. Female. Familiar in a way that didn’t register through the fog of sleep and lust. I slammed in harder, pounding the mattress, the headboard knocking the wall. Sweat slicked our skin. I reached between us and rubbed the swollen clit in tight circles while I fucked.
The orgasm hit fast and brutal. The cunt spasmed around my cock, pulsing, gushing around me as the body shook and cried out. I kept thrusting through it, chasing my own release, until I buried myself deep and unloaded, pumping thick ropes of cum straight into that spasming hole.
We stayed locked together, breathing hard. Slowly the haze cleared. The room wasn’t completely dark anymore; the streetlight outside leaked through the blinds. I looked down at the woman under me.
My sister stared back, eyes wide, mouth open, my cum already leaking out around my still-hard cock.
Neither of us moved for a long second.
Then she whispered, voice hoarse, “We didn’t… you didn’t know it was me?”
I pulled out slowly, watching my load drip from her swollen pussy. My brain tried to catch up.
She’d come home late from the bar, crashed in the guest room. I’d stumbled in after my shift, too tired to notice which bed I’d fallen into.
Her hand reached down, fingers sliding through the mess between her legs. She brought them to her mouth and licked them clean, eyes locked on mine.
“Fuck,” she breathed. “We’re not stopping now.”
She pushed me onto my back and climbed on, sinking down on my cock again, both of us slick with my cum. This time she rode me dirty and deliberate, grinding her clit against me, tits bouncing, whispering every filthy thing she’d wanted to do to me for years. I grabbed her hips and fucked up into her, watching her face twist with pleasure, feeling her get even wetter around me.
We came again, harder than the first time, her pussy squeezing every drop out of me while she moaned my name like a dirty secret.
By the time the sun came up we were still tangled together, covered in sweat and cum, already planning how we’d keep this “accident” going.
