Sheltering from the rain in the hotel with the beautiful female room manager

Yuko is a beautiful woman, has a good job and is respected in the company. However, her personal life is miserable, being the convenient mistress of her boss who already has a wife and children. One day, I went on a business trip with a poor subordinate, but due to sudden rain, I had to stay at the hotel, but due to the subordinate's mistake, I had to sleep in the same room as the subordinate. .
