In the dim glow of the bathroom, a naked woman steps into the shower, her skin glistening with water. She lathers up, her hands exploring her curves, when suddenly, the curtain is pulled back. Her brother, equally bare, stands there, eyes wide. 'What are you doing?' she gasps, but he's already seen her wet, soapy body. 'I can't help it,' he admits, his gaze lingering on her breasts. She should be upset, but her body betrays her, nipples hardening. 'Close the curtain,' she orders, but it's too late. Their taboo encounter has just begun.
