In a cramped, dimly lit room, Branquinha, a innocent-looking teen with a mischievous glint in her eye, is about to experience a taboo awakening. Her cousin, a tall, muscular man with a fat, dark cock, stands behind her, his hands gripping her tiny waist. He slowly pushes his hips forward, the thick head of his cock stretching her tight, untouched asshole. Branquinha gasps, her fingers clawing at the wall as she feels every vein and ridge of his cock sliding into her. He starts to thrust, his balls slapping against her pussy, his pace quickening as they both lose themselves in the forbidden pleasure.
