'Mushroom-Cock' captures the essence of tease and denial in this underwear bulge scene. A straight man, dressed in everyday clothes, unknowingly sports a massive erection, the outline clearly visible through his pants. His cock, a beast straining against the confines of his underwear, throbs with need. He adjusts himself, rubbing his bulge, before tentatively pulling down his pants, revealing his enormous, rock-hard cock, ready for action yet denied.
