Detective Yuna and her partner Takahashi go undercover to investigate the hideout of a criminal organization that smuggles illegal aphrodisiacs. Just as they are about to get evidence of the crime, Takahashi is caught. Yuna is captured and imprisoned in place of Takahashi and is subjected to pleasure torture. She somehow manages to escape the hideout and goes back to the hideout with Takahashi, but... Despite saying arrogant things, she cums over and over while leaking her urine... She's a really perverted masochistic woman (lol). The intense pleasure torture causes her to urinate and orgasm repeatedly!
