Maiko is a proud married office worker who remains a department manager after marriage. She keeps her staff in line and is strict but happy with the husband who works beside her. One day, a client-company president named Sagawa complains about a mistake made under her supervision. Maiko and her husband go together to apologize, but Sagawa refuses to listen and orders her to return alone. Days later, Maiko arrives for the meeting and is forced to apologize with a vibrator fixed inside her, repeatedly bowing in humiliation while being driven to orgasm.
