Momoko is not your average high school girl. In order to support her family (her younger brother and her hospitalized mother), she works as a popular author! But she doesn't write just any books, she pens erotic novels! It's quite an exciting job, but for Momoko, it is one of high stress because, you see... she is a virgin! Fortunately she has a great imagination, and does very well for herself and her family. However, because of the nature of her work she must keep it a secret.
Momoko's troubles begin when Inui Ranmaru, a popular super model and new transfer student at her school discovers her secret! In order to keep him from telling, Momoko becomes his slave?!
