Once Upon a Time in a Lingerie...2003

Urashima works at a women's underwear manufacturer in a department where all the employees are female, including the department head Kaoru, also known as Otohime-sama. One day, he is ordered by Sayori, a frustrated lingerie shop owner, to get a contract. Sayori seduces Urashima, but he is unable to get it done at the most crucial moment, which angers her. That night, Urashima picks up a turtle near the garbage dump. He goes back home and falls asleep, and dreams of a sexual feast with Kaoru and the other female employees.
