The porcelain enclosure fills with steam, the glass fogging up as the man inside lets out a low groan. His hand works furiously, jacking his rock-hard cock with precision, his grip tight and steady. The water pounds against his back, echoing the rhythm of his strokes. His other hand reaches down, cupping his heavy balls, rolling them gently, sending jolts of pleasure through him. His body tenses, abs clenching as he explodes, ropes of cum shooting out, mixing with the water swirling down the drain.
