[Reducing Mosaic]PRED-444 After learning about the true nature of my seemingly serious female colleague, Yamagishi-san... A secret week of non-stop in-out sex in the office with just the two of us. Yamagishi Houka

[A woman who looks serious is actually the most erotic! ] Only me and Mr. Yamagishi from general affairs in a quiet office. I thought I was the weak type, but we hit it off from trivial things! When I was secretly drinking in the office after work... Her eyes changed suddenly and I kissed her, and then I had raw sex in the office! I can't believe that Mr. Yamagishi was so lascivious...! Until the other employees come to work, Mr. Yamagishi and his wife, who have a ridiculous sexual desire, will never find out, and they will have an office affair!
