We were both home from college for the summer, me and my older brother Jake, sharing the same bedroom like when we were kids. Only now we were grown men, both over eighteen, and the tension had been building since the first night.
Jake was bigger, thicker in the arms and chest, always walking around in just boxers. I kept catching myself staring at the heavy bulge swinging between his legs.
One night after our parents went to bed, Jake came out of the shower with a towel barely hanging on his hips. Water still dripped down his abs. "You keep looking," he said, voice low and rough. "You want to see it or what?"
I didn't answer with words. I got up, walked over, and yanked the towel off. His cock hung heavy, half-hard already, thick and veined. I dropped to my knees right there on the bedroom floor and wrapped my hand around it. "Fuck, yeah," Jake growled. "Suck your brother's dick."
I opened my mouth and took the head in, tasting salt and skin. Jake grabbed the back of my head and pushed deeper, sliding his cock over my tongue until it hit the back of my throat. I gagged once but kept going, drooling down his shaft while he fucked my face in steady thrusts. "That's it, little brother. Take it all."
He pulled out after a minute, cock shiny with spit, and hauled me up. We stripped fast. Jake bent me over the bed, spread my ass cheeks, and spit right on my hole. "Been wanting to fuck this ass for years," he muttered. Two thick fingers pushed inside me, stretching, scissoring. I pushed back on them, moaning into the mattress.
When he replaced his fingers with his cock, he didn't go slow. One hard thrust and he was buried to the balls. The burn was intense, then the heat took over. Jake started pounding, hips slapping against my ass, balls swinging. "Tight fucking hole," he grunted. "Gonna fill you up."
He fucked me deep and dirty, one hand on my hip, the other reaching under to jerk my cock in time with his thrusts. Every time he bottomed out I felt it in my gut. Sweat dripped off him onto my back. I came first, shooting across the sheets while he kept driving into me. Jake followed seconds later, burying himself and pumping hot cum deep inside my ass.
We stayed locked together, breathing hard, until he pulled out and watched his load leak out of me. Then he flipped me over, shoved his still-hard cock back in my mouth to clean it, and told me we weren't done. Round two started with him on his back and me riding, grinding down on that thick dick until we both came again.
By morning we were still at it, swapping positions, sucking, fucking, whispering filthy shit about how wrong it was and how good it felt. We never stopped after that summer.
