In the steamy bathroom, Amador's sister, naked and wet from her shower, is startled by her brother's unexpected entrance. Their eyes meet, lingering on each other's bodies, igniting an undeniable spark. She's entranced by his growing erection, while he can't ignore her glistening curves. They argue, she calls their mother, but the tension only escalates. Later, they find themselves alone again, this time more open, more hungry. She watches him stroke his thick cock, imagines it inside her. Just as they're about to give in, a sudden noise forces them apart, leaving them breathless and craving more.
