JUL-341 The husband gritted his teeth and watched his wife have sex with her partner

I run a company and have been married to my wife Yuko for two years. Yuko was originally an employee of the Koizumi company, which was her subcontractor, and took Koizumi away from Yuko under the condition of an absorption-style merger. To bask in the feeling of superiority and to show off, once a week, Koizumi, who is placed near her assistant, sits behind a magic mirror to demonstrate the couple's activities. Two years after getting married, she thought that Yuko was completely mine, both physically and mentally. However, every Wednesday, Yuko has a secret meeting with a man hiding behind her back.
