Popular beauty Yumika Saeki undergoes a bizarre genital reversal: her mouth becomes a pussy, her tongue becomes a clitoris, and her pussy becomes a mouth. She is taken outside for a humiliating public walk while forced to spread her newly transformed mouth-pussy. Back at the hotel, she gives a long blowjob with her pussy-mouth before a hard cock is thrust into her soaking mouth-pussy, pounding her to repeated climaxes and ending in a creampie. A 160-minute document of surreal, perverted sex.
