She came home late, the house dark except for the glow from the living room. I was on the couch, half-drunk on whiskey, when she walked in wearing that short black dress that barely covered her ass. "Couldn't sleep," she said, kicking off her heels. Her eyes locked on mine like they always did when we were alone too long. We both knew what was coming. We'd danced around it for years, but tonight the air felt thick with it.
I stood up and grabbed her wrist, pulling her close. "You know what I want," I told her, voice low and rough. "Been thinking about your tight little hole all week." She didn't pull away. Instead she pressed her body against me, tits soft against my chest, and whispered, "Then take it, brother. Fuck my ass like you've been dying to."
We didn't waste time with slow kisses. I spun her around, bent her over the arm of the couch, and yanked that dress up over her hips. No panties. Her bare ass cheeks spread just enough for me to see the tight pink ring I wanted. I spit on my fingers and rubbed her asshole, pressing one finger inside. She moaned, pushing back against my hand. "More," she begged. I added a second finger, stretching her open while my cock strained against my jeans.
I freed my dick and rubbed the head against her wet pussy first, coating it in her juices before sliding it up to her ass. She was breathing hard, hands gripping the cushions. "Do it," she said. "Shove it in my ass." I pushed the head past her tight ring and kept going, inch by inch, until my balls rested against her. She was so fucking tight it almost hurt. I held still for a second, letting her adjust, then started thrusting.
Every stroke was deep and filthy. Her asshole gripped my cock like it was made for it. I slapped her ass hard, leaving red handprints, and she pushed back harder, taking every inch. "Harder, fuck my ass harder," she gasped. I grabbed her hips and pounded into her, the wet slap of skin on skin filling the room. She reached down and rubbed her clit while I wrecked her hole, her moans turning into sharp cries every time I bottomed out.
I pulled out, flipped her onto her back on the couch, and lifted her legs over my shoulders.
Her asshole was gaping a little now, shiny with spit and her own slick. I slammed back in, watching her face twist with that perfect mix of pain and pleasure. "You love your brother's cock in your ass, don't you?" I growled. She nodded, biting her lip. "Yes. Fill it up. Come in my ass."
I fucked her like that until my balls tightened. When I came, I buried myself to the hilt and pumped thick ropes of cum deep inside her ass. She came too, fingers working her clit fast, her whole body shaking around my cock. I stayed inside her until I softened, then slowly pulled out, watching my load leak from her stretched hole.
We didn't talk much after. She just pulled her dress down, kissed me once on the mouth, and went to bed. We both knew it wouldn't be the last time.
