Curvy manager Mirei Imada spends the night at a love hotel with her boyfriend and comes to work without panties. A subordinate notices and secretly photographs her bare, shaved pussy. He uses the photo to blackmail her into giving him an office blowjob, claiming she must deal with the desire she caused. On another night he fucks and creampies her during overtime; later he orders her to strip and masturbate on the desk before another creampie. With the leverage still hanging over her, their twisted office sex arrangement looks set to continue indefinitely.
