The steam room door clicked shut behind him, and Mark knew exactly what he wanted. He dropped his towel on the bench and stood there naked, cock already half-hard from the heat and the thought of what might happen. Across the tiled room, another guy leaned back against the wall, legs spread, stroking himself slow and steady. Thick dick, veiny, balls hanging heavy. Their eyes locked.
"You gonna watch or you gonna come suck it?" the guy said, voice low and rough.
Mark crossed the room in three steps and dropped to his knees. No talking, no names. He wrapped his lips around the head and took it deep, tongue flat against the underside. The guy groaned and grabbed the back of his head, pushing him down until his nose pressed into trimmed pubes. Mark gagged once but kept going, throat working, spit running down his chin onto the floor. He sucked hard, hollowing his cheeks, while his own cock throbbed untouched between his legs.
"Fuck yeah, take it all," the guy muttered. He started thrusting, fucking Mark's mouth in short, dirty strokes. Precum coated Mark's tongue, salty and thick. Mark reached down and jerked himself fast, matching the rhythm. The steam made everything slick, skin hot and wet.
After a minute the guy pulled out and hauled Mark up by the arm. "Turn around. Hands on the bench."
Mark bent over, ass up. The guy spit on his hole and worked two fingers in without warning, stretching him open rough and quick. Mark pushed back, moaning. "More. Fuck me already."
A condom wrapper tore.

Then the thick head pressed against his rim and shoved inside in one hard thrust. Mark grunted, hole burning around the stretch. The guy didn't wait. He gripped Mark's hips and started pounding, balls slapping against ass with every stroke. The sound was wet and filthy, skin on skin echoing off the tiles. Steam swirled around them while the guy fucked him deep, pulling almost all the way out before slamming back in.
"Goddamn, this ass is tight," the guy growled. He reached around and grabbed Mark's cock, stroking it in time with his thrusts. Mark's legs shook. He came first, shooting ropes across the bench and floor, hole clenching hard around the dick inside him. The guy fucked him through it, then pulled out, ripped off the condom, and painted Mark's lower back with thick spurts of cum.
They stayed like that for a moment, breathing hard. Then the guy wiped his dick on Mark's ass cheek and walked out without another word. Mark stayed bent over, cum cooling on his skin, already wondering who would walk in next.
