In the dimly lit room, Rosa Vermelha Gp's stepbrother can't help but notice his sister's half-lidded eyes and flushed cheeks. She's lost in her own world, her hand moving under her skirt, her pussy slick with arousal. He watches, entranced, as she brings herself closer to the edge, her breath hitching as she imagines it's his fingers, his cock, stretching her, filling her, making her come undone. He can't resist the urge any longer, moving closer, his own hand mirroring hers, their eyes locked, their bodies yearning for the taboo.
