The female president "Kanna Misaki" was a lewd sex addict who was trying various suspicious erection drugs on men. So, they decided to call her in using a new product, "Super Erection Drug," as bait. Special transgender investigator "Mumu Kondou" was given the order to secure the transaction site, but she was caught by them who knew everything and became a test subject for the super erection drug. Mumu, who was intensely aroused by the effects of the drug, couldn't resist the pleasure and had no choice but to abandon herself to the lewd experiment... #DickP
