Binyuu Chousain Ayako

Ayako Yaginuma, a housewife longing for her husband's affection, decides to seek counseling for her unfulfilled desires. On her way to the appointment, she gets lost and stumbles upon Professor Hayao Nuregashira, a researcher studying human sexual behavior. Mistaking her for a volunteer, the professor subjects Ayako to a series of erotic experiments, quickly discovering her insatiable libido.

Impressed by her boundless appetite, the professor appoints Ayako as the head researcher for various sexual topics. Now surrounded by the carnal satisfaction she craves, Ayako eagerly embraces her new role. However, this arrangement may lead to consequences beyond mere physical pleasure.
