The company motto of this black company is "total service." The employees, played by Hanagoromo Tsubaki and Adachi Yuri, are faced with endless "deep throat overtime." They kneel under their desks, accept their superiors' cocks deep in their throats, and continue to serve while vomiting and drooling. They are not allowed to escape, and the sight of their throats being violated, accompanied by a dull thumping sound, is pure hell. The cruelty of the process in which female employees are reduced to mere sex toys in the closed space of the office is evident. This is an extreme oral sensual record that depicts the domination and subjugation that are unique to black companies.
