In the sultry heat of a Brazilian summer, cousins Cuzinho and Novinha find themselves alone in the family home. As they lounge by the pool, their eyes wander, and the air grows thick with unspoken tension. Novinha, a innocent yet curious novinha, can't help but notice Cuzinho's growing bulge. Emboldened by the heat and a few drinks, she asks him to teach her about the pleasures of the flesh. Cuzinho, despite his reservations, can't resist her charms. He guides her hand to his throbbing cock, and as she tentatively strokes him, he whispers instructions in her ear. Their forbidden encounter is a dance of innocence and experience, a tangled web of desire and taboo.
