Rei is an extremely talented female employee with a very high level of education but extremely shy. Taking advantage of this point, the head of the department repeatedly sexually harassed her. But because there is no father or siblings, only one girl to take care of her sick mother, Rei cannot quit her job. In order to capture Rei, the head of the department deliberately played a trick on her documents. He then blamed all the blame on Rei, forcing her to obey him if she wanted his help in resolving the matter. There was no other way, Rei had to agree. And since then, he has been constantly making her wear lewd lingerie to the point that prostitutes even blush. He made her serve him sexually at the company. He also used her as a "reward" for other employees. He even forced her to serve as a partner right at the company. Rei is nothing more than a toy, anyone can fuck her, her body never gets a break, and such days seem to have no end...
