I never planned on fucking my brother, but once his thick cock was in my mouth there was no turning back. It started on a humid Friday night when Mark showed up at my apartment after his shift at the bar. He was twenty-six, same as me, broad shoulders still damp from the rain, that familiar smirk on his face.
We’d always been close, closer than most brothers, but the air between us had been crackling with something heavier for months.
We cracked open beers and talked shit about work, girls, nothing important. Then the conversation slid. Mark leaned back on my couch, legs spread, and said, “You ever think about how we used to jerk off in the same room as kids?” His voice was low, dirty. My dick twitched before I could stop it.
“Yeah,” I answered, already hard. “I used to listen to you.”
Mark’s eyes darkened. He reached down and squeezed the bulge in his jeans. “You want to listen again? Or you want the real thing?”
I didn’t answer with words. I dropped to my knees between his thighs and yanked his zipper down. His cock sprang out, heavy and veined, already leaking. I wrapped my hand around the base and licked the head, tasting salt and skin. Mark groaned, deep in his chest, and grabbed my hair.
“Suck it, little brother. Show me how bad you want it.”
I took him deep, gagging when the head hit the back of my throat. He tasted like sweat and beer and everything I’d been fantasizing about alone in bed. Mark fucked my mouth in short thrusts, hips rolling, telling me how tight my throat felt, how he’d jerked off thinking about my lips wrapped around him. Spit ran down my chin onto his balls. I moaned around his shaft, reaching down to stroke myself through my pants.
When he pulled me off, strings of spit connected my mouth to his cock. “Strip,” he ordered. I stood, peeled everything off, and stood naked in front of him. My own cock was rigid, head shiny. Mark looked me over like he was deciding where to start.
He shoved me onto the couch, face down, ass up. His rough hands spread my cheeks and he spat right on my hole. One thick finger pushed inside, then two, stretching me while he muttered filthy praise. “Tight little hole. Been saving this for your big brother, huh?”
I pushed back on his fingers, begging. “Fuck me, Mark. Want your cock.”
He didn’t make me wait. He lined up and sank in with one long thrust. The burn was perfect, deep, filling me completely. Mark bottomed out and stayed there, grinding, letting me feel every inch. Then he started pounding, balls slapping my ass, the couch creaking under us. Every thrust punched a moan out of me. He reached under and stroked my cock in time with his hips, calling me his dirty little brother, telling me how good my ass milked him.
We switched positions twice. First I rode him, facing him, watching his face while I bounced on that fat dick. Then he flipped me onto my back, legs over his shoulders, and fucked me harder, deeper, sweat dripping from his chest onto mine. When he came he buried himself to the root and flooded me, hot pulses I could feel. The feeling pushed me over; I shot across my own stomach without touching myself.
We stayed locked together, breathing hard. Mark pulled out slow, watching his cum leak from my hole. Then he leaned down and licked it up, tongue pushing inside me, cleaning his own mess. The sight made me hard again almost instantly.
Round two was slower but no less filthy. He sat on the edge of the bed and had me stand in front of him so he could suck me while fingering my cum-slick hole. I came down his throat and he swallowed every drop. Later he bent me over the kitchen counter and fucked another load into me, one hand over my mouth to keep the neighbors from hearing how loud I got.
By morning we were sore, sticky, and grinning like idiots. Mark kissed the back of my neck while we showered and said, “This isn’t ending. You’re mine now.”
I pushed back against him, feeling him harden again. “Then fuck me in the shower and prove it.”
We didn’t leave the apartment all weekend. Every room got used. Every position. Every filthy word. And every time he called me his brother while he was buried inside me, I came harder than I ever had before. Reddit can have the story. The real thing is staying between us.
