Jounetsu no Are

Maki is living with her boyfriend, but they haven't had sex in 2 years. Unable to ask him directly or confide with her friends, she constantly worries about whether she's no longer attractive as a woman. One day, Maki's mother's collapses from overwork, and Maki has to help out at the toy store she manages. But when she gets there, it's actually an "adult" toy store!
