In a cramped room, Jaolucas, a young man with a slim body and average height, is initiated into the world of gay sex by his dominant roommate, Meu Detonador. The muscled, tattooed Jaolucas is hesitant but excited, his huge body trembling with anticipation. Meu Detonador, a Latino man with a muscular body and a commanding presence, trains Jaolucas to lick and pleasure him, making him scream in submission. The casting session turns into a dirty, sweaty encounter, with Jaolucas' muscles tensing as he explores his first-time bisexual experience.
