Hibiki can't forget her deceased boyfriend, so she coincidentally orders a men's love doll that looks just like him, marketed as a guide for women's romantic experiences. For her, the longing to relive the carnal memories with her boyfriend outweighs the desire to start a new relationship. She finds deep satisfaction in the intense tongue-kissing and erotic play with the doll, including flipping it over and licking its anal area. As she rides the doll in a cowgirl position with her legs spread wide, she can't help but feel like she's embracing her boyfriend again, caressing his body with her big ass. However, a shocking secret hidden within the doll, which looks just like her boyfriend, sets off a chain reaction in Hibiki's heart.
