Investigator YUNA decides to conduct an undercover investigation with her partner Takahashi into the hideout of a criminal organization that is secretly selling illegal aphrodisiacs. Takahashi is caught just as he is about to get evidence of the crime. YUNA, who is captured and imprisoned in place of Takahashi, is subjected to pleasure torture. Somehow escaping from the hideout, she re-enters the hideout with Takahashi... Despite saying all sorts of important things, she's cumming like crazy while pissing herself... She's an incredible perverted masochistic woman (laugh). Intense pleasure torture leads to repeated incontinence orgasms!
