A sexy shop where bunny girls provide service. 'Hikaru' is the absolute No.1 of this shop, but her personality is the worst, and she often bullies other bunny girls. One day, a new girl named 'Saya' joins the shop. As usual, Hikaru starts bullying the new girl, but it turns out that this 'Saya' is a yakuza woman. The yakuza uses underlings to rape 'Hikaru', takes photos, and blackmails her instead. Thus, the No.1 bunny girl falls into becoming a sex slave. Awaiting her are full-nude dogeza, in-store live sex shows, and gangbang bukkake sex...
