In the dimly lit, steamy gym, muscle-bound men in tight shorts gather for a secret session of self-pleasure, inspired by the infamous 'Fight Club' rule. Their massive cocks tent their shorts as they stroke and grunt, eyes locked on each other's bulges. A black, military-chiseled stud joins the group, his huge cock stretching his camo briefs. He's new, but the others eagerly make room, ready to welcome him into their sweat-soaked, gay, group masturbation club.
