A bizarrely styled café in a bustling Tokyo area. Pink-haired girls, heavily made-up, smile blankly and say, "Welcome back?" Meanwhile, "we"—the regulars and the manager—are plotting a deal. At an after-get off work "celebration party," they give the girls drinks laced with imported stimulants. "Just a little trick, and you'll be instantly aroused." Initially, the atmosphere is relaxed and pleasant, but soon breathing becomes rapid, some tear open their clothes, bodies touch, eyes entwine. Unbeknownst to them, everyone is immersed in pleasure, beginning a group drugged sex session.
