In a cramped, dimly lit room, Martin, the 'pasivo', awaits his 'activo' for the night, Tio, his friend's uncle. As soon as Tio enters, Martin drops to his knees, ready to serve. Tio, a dominant 'cachero', grabs Martin's hair, guiding his head to his crotch. Martin eagerly unzips Tio's pants, taking out his hard cock and swallowing it whole. Tio face-fucks Martin, making him gag and drool, before bending him over and fucking him hard, bareback, making Martin's 'sumisa' side scream for more.
