Taking advantage of frequent visits to his house to fuck his colleague's wife

Come over to my house and fuck my colleague's wife. He has been married to his wife Nao for several years. He has now been promoted to sales manager and has built a good relationship with Nao. One day, the topic of marriage with Suzuki, a subordinate of the company, was too negative, so I decided to experience a fake couple with Nao to feel the goodness of marriage. That day, Suzuki had three hours alone with Nao. Suzuki seemed to like it too, and a few days later, he asked me to be a fake couple again. At that time, I readily agreed without any doubt.
