Tiago, the horny brother, can't resist his cousin Fabricio's charms. As Fabricio showers, Tiago sneaks in, stroking his thick, uncut cock. Fabricio, surprised yet aroused, joins in. They jerk off together, Tiago's breath hitching as Fabricio's massive length grows. Just as Tiago leans in for a taste, they hear the door. They rush to hide, hearts pounding, as Tiago's sister enters, unaware of their forbidden encounter.
