Struggling to find inspiration, author Saki Sasame goes to stay at an inn, arriving at the same time as a group of women who are strangers to her. Having been hired at the inn just six months ago, shy and young Takumi Satou has difficulty dealing with the female guests—but he is troubled most of all by Saki and her unprompted cold demeanor toward him. After his coworker Hikari Kikuchi is late in returning from her duty, Takumi goes to Saki's room to check up on Hikari—only to find her nearly naked and tied up. Hikari claims that it is Saki's doing, but she seems to be withholding the entire truth.

As it turns out, Saki is an erotic novelist who intends to use Takumi for her newest work; therefore, she has asked Hikari for assistance. Despite his initial reluctance, Takumi finds himself dragged into the two's unusual plans and promptly involved in several lustful encounters.
