In the dimly lit, sweaty gym, two muscular, uncut amateurs, Carlos and Juan, catch each other's eye. They strip down to their jockstraps, their thick, veiny cocks tenting the fabric. Leaning against the weight bench, they stroke each other's meat, groaning as their foreskin slides back and forth. Carlos, the bigger of the two, spits on his hand, lubricating Juan's shaft. They grunt and thrust, balls slapping against each other, until Carlos can't take it anymore. He pushes Juan down, and in one swift move, buries his raw cock deep into Juan's tight, hairless hole.
