She tied the blindfold tight over her eyes and lay back on the bed, legs spread, heart pounding like she was about to get caught. "Don't say a word," she whispered. "Just fuck me like you own this pussy."
I was already rock hard, staring at my sister's shaved cunt glistening under the dim bedroom light. We were both adults, both knew exactly what the fuck we were doing, and that blindfold was the only thing keeping it from feeling too real. She thought the game made it hotter. I thought it made me want to pound her even harder.
I climbed between her thighs and dragged the head of my cock up and down her slit, smearing her wetness all over myself. "You're dripping already," I muttered, voice low. "Such a filthy little sister, getting wet for this."
She moaned and lifted her hips, trying to take me inside. I slapped my cock against her clit instead, watching her squirm. "Beg for it."
"Please," she hissed. "Shove that cock in me. Fuck your sister's cunt like you mean it."
I slammed in deep on the first thrust. Her pussy clenched around me, hot and tight, sucking me in like it was made for my dick. I grabbed her hips and started pounding, skin slapping loud in the quiet room. Every time I bottomed out she let out a dirty little grunt, tits bouncing with each hard stroke.
"Goddamn, you feel so fucking good," I growled, leaning down to bite her neck. "This blindfold makes you even sluttier. You can't see who's wrecking you, but your body knows it's me."
She reached up, fingers digging into my shoulders. "Harder. Fuck me harder. Make me come on my brother's cock."
I flipped her onto her stomach, yanked her ass up, and drove back in. Her face pressed into the pillow, blindfold still secure. I spread her cheeks and watched my thick shaft disappear into her soaked hole, glistening with her juices every time I pulled out. I reached under and rubbed her swollen clit in rough circles while I fucked her.
"You're gonna come for me," I said, voice rough. "Come on this dick like the dirty incest slut you are."
Her whole body shook. She cried out, muffled by the pillow, pussy pulsing and gripping me tight as she came. I didn't stop. I kept slamming into her through the orgasm, chasing my own. Sweat dripped down my chest onto her back. The smell of sex filled the room.
When I pulled out she whimpered at the emptiness. I flipped her again, straddled her chest, and fed my cock into her open mouth. She sucked greedily, tasting herself on me, tongue swirling around the head while I fucked her face. Spit ran down her chin. I held the back of her head and used her mouth until my balls tightened.
I pulled free and stroked fast, aiming at her tits. Thick ropes of cum splattered across her skin, some hitting the blindfold. She licked her lips, smiling like she'd won.
"Take it off," she panted after a minute. "I want to see your face when you fuck me again."
I untied the blindfold. Her eyes met mine, dark and hungry. No pretending now. Just raw need.
"Round two," she said, spreading her legs again. "And this time don't hold back."
We didn't. We fucked until the sheets were soaked and her voice was hoarse from moaning my name. The blindfold stayed on the nightstand for the rest of the night, but the secret stayed between us, hotter than ever.
