Yuki Yuki Chitose turns into a drug-sex slut with a bouncy, tanned body! Sanada harbors feelings of resentment towards his female boss Chitose, who constantly scolds him for making mistakes at work. Every year, she comes back from vacation showing off her healthy tan lines, so he devises a plan to humiliate her and bring her down. His plan is to give Chitose a powerful aphrodisiac to make her horny, then have her expose a lewd appearance at work and put an end to her socially. Sanada successfully gives Chitose the aphrodisiac, but for some reason, the sexual desire of this horny Chitose is always directed towards Sanada himself...
