Perverted old boss rapes busty employee

I decided to leave the company where I had worked for a long time. To celebrate the anniversary, everyone in the department went on a hot spring trip as well as a farewell party. We were comforted by the lonely hot spring inn, away from the hustle and bustle of the city. From the moment I joined the company until the farewell party, I am truly grateful to Director Matsuo. And at the dinner party, I drank too much, and it seemed that I was drunk before I knew it. At that moment, I didn't realize that this trip was one planned by the director.
