Juan retreats to the bathroom, seeking solace in masturbation. He strips naked, his erect pene throbbing with desire. He strokes it slowly, his mind filled with lurid fantasies. The sound of running water and his own heavy breathing fill the small room. Suddenly, the door swings open, revealing his mother. Shock and humiliation flash across Juan's face as she gasps at the sight of his naked, aroused form. "What are you doing, Juan?" she demands, her voice sharp. He stutters an apology, trying to cover himself with his hands. She shakes her head, disappointment clear in her eyes, and leaves, closing the door behind her. Juan is left alone with his shame and his unsatisfied desires.
