A muscular twink, naked and alone in the shower, decides to indulge in some solo pleasure. He lubes up a generous-sized dildo and mounts it, impaling himself with a satisfied groan. The water cascading down his body only heightens the sensation as he rides the toy with increasing fervor, his own hard cock bouncing. He's so lost in the moment that he doesn't hear the bathroom door creak open. A voice gasps, "What are you doing?" Startled, the twink freezes, dildo still buried deep inside him, as he turns to face the unexpected intruder.
