Raping a married secretary in a private room

Mitsumi An is a girl I've liked since she joined the company. However, she is married to Ando, who is also my employee. I get really irritated every time I see the two of them working and having fun together. I had to do something to win her over. An offered An to be my secretary but she refused. Then one day Ando made a big mistake at work. Now An volunteers to be my secretary and not only that, she also does whatever I want in exchange for her husband's career. We fucked a lot in the president's office behind closed doors.
