The joint burned down between Jake's fingers as he passed it to his roommate Marcus on the couch. They were both twenty-five, both buzzed hard from the strong weed, the room hazy and the TV forgotten. Jake's cock was already half-hard in his shorts from the high and from the way Marcus kept looking at him.
"Fuck, I'm so high," Marcus muttered, his voice low and rough. "You ever think about dudes when you're like this?"
Jake laughed but didn't look away. "Yeah. Especially right now. My ass feels… open or something."
Marcus set the roach in the ashtray and leaned in. "Show me."
They stripped fast, clothes hitting the floor. Jake's dick stood up thick and leaking. Marcus's was longer, veined, already dripping. Marcus grabbed lube from his room and came back, pushing Jake onto his stomach on the couch.
"First time, right?" Marcus asked, voice direct.
"Yeah. Never had a cock in me."
Marcus poured lube over Jake's hole and worked two fingers in without warning. Jake grunted, the stretch burning but the high turning it into something hotter, deeper. "Shit, that's tight," Marcus said, pumping his fingers. "Gonna wreck this virgin ass."
He pulled his fingers out and pressed the head of his cock against Jake's hole. "Breathe." Then he pushed. The thick head popped in and Jake yelled, the burn sharp and real. Marcus didn't stop. He fed inch after inch into Jake's ass until his balls rested against Jake's skin.
"Fuck, you're taking it all," Marcus growled. He started thrusting, slow at first then harder, the slap of skin loud in the room. Jake's cock rubbed against the couch cushion, leaking steadily. Every stroke hit something inside that made his whole body jerk from the high.
Marcus grabbed Jake's hips and fucked him deeper, dirty talk pouring out. "This what you wanted? Your first time getting your ass pounded while you're high as fuck? Feels good, doesn't it? Your hole's gripping my cock like it was made for it."
Jake pushed back, meeting every thrust. "Harder. Fuck me harder."
Marcus flipped him onto his back, hooked Jake's legs over his shoulders, and drove in again. The new angle made Jake moan loud. Marcus's cock dragged over his prostate with every stroke, lube and pre-cum making everything slick and filthy. Jake reached down and stroked his own cock in time with the pounding.
They stayed like that, Marcus hammering deep, sweat dripping, the weed making every sensation ten times stronger. Jake came first, shooting thick ropes across his own stomach and chest without touching his cock much. His ass clamped down hard. Marcus groaned and buried himself to the root, pumping cum deep inside Jake's hole in hot pulses.
They stayed locked together, breathing heavy. Marcus pulled out slow, watching his load leak from Jake's stretched, used hole.

Jake lay there wrecked and grinning, still floating.
"Round two when we smoke another one," Marcus said, already reaching for the grinder.
