Jake spotted him the second he walked into the gym steam room. The guy was built thick, broad shoulders slick with sweat, a heavy cock hanging between his legs as he sat on the tile bench. No towel.

Just skin and muscle. Jake dropped his own towel and sat opposite, legs spread so the stranger could see everything.
The guy looked up. "You here to sweat or stare?" His voice was low and rough.
"Both," Jake said. He reached down and gave his own cock a slow stroke. It thickened fast under the heat and the attention.
The stranger stood and crossed the small room. No words wasted. He grabbed Jake by the hair and shoved his face into his crotch. "Open up then."
Jake took the thick cock in his mouth without hesitation. It tasted like salt and musk. He sucked hard, tongue working the underside while the guy held his head and thrust shallow at first, then deeper. Spit ran down Jake's chin. The stranger grunted and pulled out, strings of saliva connecting them.
"Turn around. Hands on the bench."
Jake obeyed. The tile was hot under his palms. The guy kicked Jake's feet wider, spat on his hole, and rubbed the head of his cock against it. No lube, just spit and sweat. He pushed in slow but steady, stretching Jake open until his balls rested against Jake's ass.
"Fuck, that's tight," the guy growled. He started pounding right away, hips slapping loud in the small room. Each thrust drove Jake forward. The stranger reached around and jerked Jake's cock in time with his fucking, grip firm and fast.
Jake moaned and pushed back, taking every inch. "Harder. Use that hole."
The guy obliged, slamming in deeper, grunting with every stroke. Sweat poured off both of them. The smell of sex mixed with the steam. After a few minutes the stranger pulled out, spun Jake around, and shoved him to his knees again. Jake sucked his own ass taste off the cock, gagging when it hit the back of his throat.
"Stand up. Against the wall."
Jake braced his hands on the wet tile. The guy entered him again from behind, one arm around Jake's chest, the other stroking his cock. They fucked standing until Jake's legs shook. The stranger came first, flooding Jake's ass with thick pulses, then kept thrusting through it until Jake shot across the wall, ropes of cum mixing with the condensation.
They stayed locked together, breathing hard. The stranger pulled out slow, cum leaking down Jake's thigh. He slapped Jake's ass once.
"Same time tomorrow?"
Jake nodded, already half-hard again. "Bring a friend if you want."
