The blindfold was her idea. She said it would make everything hotter, dirtier, more intense. I tied the black silk over my eyes in the hotel room, already hard just from the sound of her voice telling me to strip and lie back on the bed. My cock stood straight up, throbbing, waiting for whatever she had planned. We had met on some app two weeks earlier, both looking for no-strings, raw fucking. She was older than me by a couple years, curvy, and loved calling the shots.
I heard the door click open. Footsteps. The bed dipped. A warm hand wrapped around my shaft and gave it a slow, firm stroke. "Fuck yes," I groaned. Her mouth followed, hot and wet, sliding down my length until her lips met her fist. She sucked hard, tongue swirling, taking me deep like she knew exactly how I liked it. I bucked my hips, fucking her mouth, the blindfold making every sensation sharper.
She climbed on without a word. Her thighs straddled me, and she rubbed her soaked pussy along my cock, coating it in her slickness before sinking down. Tight, hot, perfect. She rode me slow at first, then faster, slamming her hips down so her ass slapped against my thighs. I grabbed her waist, thrusting up to meet her, grunting every time I bottomed out. "Your cunt feels so fucking good," I growled. She moaned but stayed silent, just grinding and bouncing like she was possessed.
We switched. I flipped her onto her back, ripped the blindfold off, and drove into her hard. Her tits bounced with every thrust. I pinned her wrists, pounding deep, watching her face twist in pleasure. She came first, pussy clenching around me, soaking the sheets. I followed seconds later, flooding her with thick ropes of cum, hips jerking as I emptied everything inside her.
Only then did I really look at her face in the low light. My stomach dropped. It was my stepsister, Lena. We hadn't seen each other in five years since our parents split. Same eyes, same birthmark on her collarbone, same fucking everything. She realized it the same second, eyes going wide.
We both froze, my cock still twitching inside her, cum leaking out around it. "Oh shit," she whispered. Neither of us moved. My dick stayed half-hard, still buried in her. The heat, the smell of sex, the way her walls fluttered around me… it didn't go away. It got worse.
She shifted her hips, a tiny involuntary roll, and a fresh wave of slickness coated me. "We should stop," she said, but her voice was thick and her nipples were tight. I pulled out an inch and pushed back in, testing. She gasped. I did it again, slower, watching her bite her lip. "This is so fucked up," she breathed, but her legs wrapped around me.
I started fucking her again, raw and deliberate. Every thrust made wet sounds from the mess already inside her. "Your pussy's gripping me like it wants more," I said, voice low and dirty. She moaned and met every stroke, nails digging into my back. We didn't talk about who we were. We just fucked like animals, switching positions again and again. Doggy, her ass up and face down while I railed her from behind, slapping her cheeks red. Then her riding me reverse, watching my cock disappear into her cum-filled hole. She came twice more, screaming into the pillow the second time.
When I finally pulled out, my load poured out of her in thick globs. We lay there panting, staring at the ceiling. The guilt hit, but so did the afterglow. She reached down, scooped some of my cum onto her fingers, and licked it off without looking at me. My cock twitched back to life.
Round two was slower but no less filthy. I ate her out, tasting my own cum mixed with her juices, tongue fucking her until she squirted on my face. She sucked me clean and then climbed on again, this time facing me, riding with deep grinds while we locked eyes.
"We can't tell anyone," she panted. I agreed by flipping her and pounding her into the mattress until I came again, adding to the mess.
We showered together afterward, soapy hands exploring like we were still figuring out how far we'd go. By morning we had fucked three more times. Each time the "accidental" part faded a little more into raw need. When we finally checked out, we didn't make plans, but we both knew this wasn't the last time our bodies would betray us like that. The secret just made every future fuck hotter, dirtier, and more inevitable.
