Yuzu-sama, the mischievous little queen, captivates with her pure smile as she torments her male masochist. At Perversion Maniac Headquarters, she meticulously and intensely trains an M man who has volunteered to become her human toilet. The first stage involves an intensely erotic act: Yuzu-sama feeds him food she has chewed, transferring it mouth-to-mouth. He is forced to swallow everything—salad, pudding, cake—along with her saliva, nasal mucus, and phlegm. Finally, to fulfill his role as a urinal, he must drink her urine, experiencing the ultimate degradation.
