Angel Santana is determined to get completely toned in order to appeal to women, so he has asked his athletic buddy,
Arno Antino, to provide him with some fitness advice at his brand new in-house gym. As they engage in physical activities and start perspiring, Arno uses extremely graphic sexual language to encourage Angel, leading to Angel unintentionally experiencing an erection. Unable to proceed with the workout under these circumstances, Angel finds himself without a private space to masturbate in the house.
Arno suggests that they should just masturbate together right there. Arno proposes this plan so that they can quickly resume focusing on making maximum physical gains. They masturbate back to back initially, but their curiosity gets the better of them, prompting them to explore further.
They rationalize this intimate act as another type of physical exertion.
