Knocken, the bold exhibitionist, seeks thrill in the unlikeliest of places - a bustling restroom. He finds solace in stall #4, where he begins to stroke his hardening cock, eyes darting to the door, hoping for an audience. The sound of the lock clicking open sends a jolt of excitement through him as he picks up the pace, his hand working feverishly. The thrill of being caught intensifies as he nears his climax, his breath ragged, until finally, he can't hold back any longer, and he releases, his cum shooting onto the floor.
