Gustavo Borges, a young, fit Brazilian with an average, proportionate build, finds solace in his workout routine. But today, his new gym partner, CapixabaXXL, a heavily-tattooed, heavily-muscled giant, turns their session into a fetish-filled, erotic spectacle. Capixaba's huge, tattooed body and perfect ass hypnotize Gustavo, who can't help but jerk off to the sight of Capixaba licking his own sweat and flexing his muscles. The workout turns into a mutual masturbation session, with Capixaba's dirty talk driving Gustavo to the brink of ecstasy.
