"Oh my penis!" he exclaims, as he discovers the pleasure of his own touch. His underwear-clad body writhing, he grips his erection, feeling the smooth skin and hard core. He's a master of his own domain, his grip tightening, his strokes becoming more urgent. His breath hitches, his body tenses, and with a final, powerful stroke, he finds his release, his underwear and hand coated with his warm, sticky cum.
