Mark Wright, a crossdressing sissy, finds himself in a degrading yet arousing situation. Dressed in lacy panties and a bra, he feels the urge to piss, and instead of using the toilet, he lets go right there, soaking his lingerie. The humiliation turns him on, and he decides to take it a step further. He leans over, lapping up his own piss from the floor, savoring the salty taste. With a moan, he swallows every last drop, his hard cock straining against the wet fabric.
