Two years after I joined the cosmetics company, I was on a day trip with my older colleague Muto. Muto-senpai is a beautiful woman who is good at her job and is my favorite female boss. However, a business negotiation with her business partner doesn't go well and she ends up staying overnight. Unfortunately, all the hotels were fully booked, so I ended up staying alone with Muto-senpai in the one empty room I managed to find. As the alcohol progressed, the women started talking with each other.
