Missing the last train, he finds himself alone in a run-down guesthouse with a K-cup new employee… Unbeknownst to him, this busty subordinate reveals her instinctive nature, swaying her breasts and waist against her boss. (Minato Yuru, SONE-155)

My busty subordinate is a perverted woman who's obsessed with her boss's penis—I took a new female employee on a business trip to the countryside. Our original plan was to go home that night, but the Shinkansen was canceled due to heavy rain, so we had to find a hotel. However, we couldn't find any hotels in the countryside, and ended up staying at a run-down guesthouse with only one room. Even though my boss is married, I reluctantly agreed. As I was taking a shower, having composed myself, I suddenly heard a "thump, thump, thump" sound, and my beautiful subordinate with her K-cup breasts walked in.
