I went on a business trip with Gunji-san, who is said to be a strict boss. My colleagues said that he was scary when he was angry, but to me, he was a reasonable boss and someone I admired. The business negotiations went well and we got a big contract, but the trains on the way back were not running, so we had no choice but to look for a place to stay. We finally found a hot spring inn, but there was only one room available, so I ended up spending the night with Gunji-san. It was sudden, but the dinner was luxurious and there was an open-air bath, so I was excited to see such a nice inn. We had some alcohol with the meal, and I was Kokoro by Gunji-san's pink cheeks. I was so happy and excited that I don't remember what we talked about, but I was holding him in my arms. Gunji-san was surprised and kissed me a little shyly. From there, we played with each other's bodies and made love. The next morning, I woke up to her kiss, and I wanted my senior's body again, knowing that the events of the previous day were not a dream. And we desired each other as much as we could...
