Two strangers locked eyes across the dim bar, and within minutes they were in the alley behind it, no names exchanged. Jake shoved Mark against the brick wall, yanking his jeans down to his thighs. "Gonna fuck this tight ass raw," Jake growled, spitting on his thick cock and rubbing the head against Mark's hole. Mark pushed back, hungry for it. "Do it, man. Pound me like you mean it."
Jake drove in deep on the first thrust, balls slapping skin. Mark grunted, hole stretching wide around the veiny shaft. No lube beyond spit, just pure friction and need. Jake gripped Mark's hips hard, slamming in again and again, each stroke bottoming out. "Fuck yeah, take that cock. Your ass is sucking me in." Mark's own dick bobbed hard, leaking onto the pavement as he reached down to stroke it in time with the brutal thrusts.

They didn't last long the first round. Jake pulled out, spun Mark around, and fed him the cum-slick cock. Mark sucked it clean, gagging on the taste of ass and pre, while Jake shot down his throat with a low moan. "Swallow every drop, slut." Mark did, then stood and bent over the dumpster so Jake could finger his loose hole open again.
Round two was slower but dirtier. Jake worked three fingers in, twisting and scissoring until Mark was begging. "Fuck me again. Fill my hole." Jake lined up and buried himself to the root, fucking with long, grinding strokes that made Mark's prostate sing. Sweat dripped, skin slapped, and the alley filled with wet sounds and filthy talk. "Your hole's so sloppy now. Gonna breed it." Jake came deep inside, pulsing hot loads that leaked out around his cock when he kept pumping.
They switched. Mark took control, bending Jake over and eating his own load from the stretched hole before sliding in. Jake's ass was tighter, gripping like a fist. Mark fucked him hard and fast, one hand yanking Jake's hair, the other reaching around to jerk his recovering cock. "Come on my dick, bitch." Jake shot again, ass clenching, and Mark followed, adding another load inside.
They left the alley reeking of sex, cum drying on skin, already planning the next raw session. No romance, just bodies using each other until they couldn't walk straight.
