A lonely office worker visits a men's spa and discovers that his therapist is the company's most beautiful elite employee. Company rules forbid side jobs, especially work at an erotic massage parlor, so he offers to keep her secret in exchange for intimate service. With that leverage, he exploits her inability to refuse, uses her body however he wants, and eventually calls her to his home for sex whenever he pleases, turning the proud office beauty into his obedient free-use fucktoy.
