Yuko is a beautiful and talented woman. But because she is a woman, she is always looked down upon by the useless department head. The more so, the more Yuko wants to prove herself, she throws herself into work, not caring about love affairs. Today, because she overslept, Yuko rushed to work and forgot to wear a bra. The thin shirt allows the department head to clearly see Yuko's big round breasts, her nipples seem to appear before his eyes. Seeing this, he immediately gives her a... band-aid to cover them! The company is planning to establish a subsidiary in the near future, and the director intends to send Yuko to run this company. Not allowing that to happen, the department head took advantage of the moment when Yuko was working overtime, tied her hands, stimulated her breasts and fucked her right at the company! After that, he took pictures and forced her to not wear a bra and wear a vibrator to work. Because Yuko knew almost nothing about sex, and her body was extremely sensitive, after letting him fuck her a few times, having his nipples stimulated made her body unforgettable. When he suddenly stopped paying attention to her and stopped fucking her, Yuko felt so horny she was going crazy. She ignored everything and did whatever he said, as long as he fucked her. And then, he showed the video of her masturbating to her superiors, and even forced her to appear in front of her boss without wearing a bra! After that, he was immediately appointed as the CEO of the new company. And now Yuko belonged to him, like a slave who only wanted to be fucked by him...
