Brazilian studs gather for a private lesson in punheta, the art of masturbation. Taught by a master pirocudo, they learn the nuances of stroking their engorged cocks to explosive orgasms. The room is filled with the scent of sweat and precum as the men pleasure themselves, their moans and grunts echoing off the walls. The teacher demonstrates his expert technique, his hand moving like a blur as he brings himself to the brink repeatedly, only to pull back and prolong the agony.
