Under the watchful eye of the camera, our amateur exhibitionist strips naked and slips into the tub, the water lapping at his skin. His cock, initially soft, starts to respond to the combination of warmth and his own thoughts. It thickens, lengthens, until it stands proud and rigid beneath the water's surface. He takes it in his hand, feeling the pulsing heat, the slickness of the water as he begins to stroke, his body tensing with pleasure as he explores the unique sensations of aquatic arousal.
