On a hot spring trip to celebrate my retirement from work, my boss keeps cumming inside me.

I ended up quitting my company, which I had been working for so long. To celebrate, everyone in the department came on a hot spring trip, which also served as a farewell party. We are relaxed from the hustle and bustle of the city and are soothed by a lazy hot spring inn. From when I joined the company until the farewell party, I am truly grateful to Director Matsuo... And at the evening banquet, I probably drank too much, and before I knew it, I had become so drunk... I didn't notice at the time, as it was a humiliation trip planned by the department head...
