STARS-684 Choking, Irama, Restraint... A submissive subordinate who is so addictive that he instantly turns his normal boss into a pervert and sadistic Saki Shinkai

I work as a manager at this company. His subordinate, Shinkai, has a serious attitude toward work, but he doesn't like being an athlete. One day while out drinking, I was attracted to the gap in femininity she showed me, and we started having a physical relationship. The two of us had an affair that I couldn't turn back from...As Shinkai revealed his masochistic nature, I quickly became a sadist.
