Getting drunk with a lewd boss and ending up with an employee

I work as a manager at this company. Shinkai, a subordinate, has a serious work attitude but is not good at joining sports clubs. One day, I was attracted to the void of femininity she displayed at a drinking table, and I had a physical relationship. An irreparable adulterous relationship between two people … When I was enticed by Shinkai, who was revealing his super masochistic nature, I quickly became super sad.
