The gym's dim lights cast a kinky glow over the bare-chested men, their tattoos rippling with each thrust of their hips. A thick, uncut cock bobs in the humid air, its owner stroking it lazily, eyes locked on a lithe, hairless bottom stretching on the mats. The top approaches, running a calloused hand over the bottom's smooth skin. He spits in his palm, lubing up his cock before pushing inside, making the bottom gasp. The top grips his hips, slamming into him, their bodies slapping together in a symphony of carnal hunger.
