In the dimly lit dungeon, a bound gay submissive awaits his master's touch. His hands are bound behind his back, a gag in his mouth. The master, a rugged man with a heavy Vietnamese accent, approaches, his cock already hard. He strokes it slowly, taunting the bound man, who moans in anticipation. The master then leans in, pissing a warm, golden stream onto the submissive's chest and stomach, marking him. The submissive, despite the humiliation, feels a thrill, his own cock straining against his pants. The master then gives him a slow, intense handjob, using the piss as lube, bringing him to the edge, but denying him release.
