Nagisa, a talented saleswoman, is brought to a store to entertain a client. This store, called “Oppabu”, is a place where handsome men serve customers with their beautiful bodies! Nagisa is confused, but Fuka, the cast member, is very gentle and sexy. Her hands can’t seem to stop and Nagisa can’t help but to caress him more as he reacts sexually. Turned on with her cuteness, and he becomes more and more aggressive… But while it seems like it’s just a fleeting romance between a cast member and a customer, it turns out that Fuka-san (Kazehana Zen) has a big, big secret!
