Busty office worker Mei Hosho becomes the company's obedient sex pet, serving the male employees through voyeuristic office angles and obscene group-sex duties. She is the only woman at the company and secretly the president's mistress, but while he is away on a long business trip, he orders the department manager to take good care of her in that way too. She devotes her voluptuous body to becoming the manager's personal sex doll and declares that she will offer every inch of herself for the company.
