Knocken, the insatiable exhibitionist, can't resist the allure of a public restroom in the bustling home center. With a mischievous glint in his eye, he slips into an unoccupied stall, locking the door behind him. The cool tile under his feet and the faint hum of distant shoppers heighten his arousal as he unzips, his hard cock springing free. He strokes himself leisurely, the risk of discovery only intensifying his pleasure.
