In the dimly-lit gym, two sweaty, bare-chested men lock eyes, their gaze lingering on each other's bulges. They approach, their breathing heavy from more than just exercise. One drops to his knees, unzipping the other's shorts to reveal a thick, uncut cock. He takes it hungrily, slurping and gagging as the other man grips his head, fucking his mouth. They switch, the first man now on his knees, taking the second's cock eagerly. They kiss, their tongues exploring each other's mouths, tasting their sweat and pre-cum. Standing, they embrace, their cocks pressing against each other. One lubes up and they fuck raw, the bottom's ass stretching to accommodate the top's thick cock. They grunt and groan, their movements urgent, their bodies slick with sweat and cum.
