Beautiful psychiatrist Nanami Nanami deals with perverted patients every day, but in reality, she herself is the truly abnormal one. During therapy sessions, she straddles patients' faces, rubbing her pussy against them while claiming to treat them. In her lab, she repeatedly conducts experiments to transform men into ejaculation animals. Those patients who catch her interest are imprisoned in her basement, where she abuses them daily. Yet on the other hand, her loving sex with her boyfriend occupies a tender corner of her heart. The charm of this work lies in her constantly shifting expressions and demeanor.
