A "product development project for women" has begun within the company, and Emi Asano has been singled out to be the person in charge! While we're talking about product development, we're going to carefully develop Asano's erogenous zones. Developmental sex that explores her entire body! Self-shot toy masturbation at home! 4P sex where she feels various dicks in her vagina! We follow Asano as she puts her body on the line to develop products.
