In the sultry heat of São, Matheus stumbles upon his sister's forbidden secret. Her moans echo through the house as she indulges in her carnal pleasures, unaware of his presence. The sight of her curves, glistening with sweat, ignites a fire within him. He watches, entranced, as she teases herself, her breath hitching with each touch. When she catches him, she doesn't push him away. Instead, she beckons him closer, her eyes filled with a hunger that matches his own.
