In 2009, the studio "Chichi no Ya" presented a collection of erotic stories. The first part tells about a heroine who celebrates winning a baseball tournament. She goes to her lover, who at that time was going to watch an erotic video.

This hentai features an experienced hero named Fukaya-kun, who is lucky enough to meet a beautiful and mysterious companion named Fujino. However, Fujino has an unusual feature — she cannot do without vibrators. She always carries them with her and uses them in different situations.
