A female teacher, Mr. Koizumi, came to stay for one night as a preview of a school trip. She wears a suit with great style, and black fishnet tights look great on her. Things don't seem to be going well with her husband lately, and he doesn't answer the phone when she calls him from his travels. Meanwhile, the vice principal who accompanied them tells them that they will be sharing a room tonight. She reluctantly agrees. At night, the vice principal turns over the futon and secretly reaches out to touch her body... While rubbing her fair-skinned beautiful legs peeking out of her exposed yukata, she let out a small moan as I started licking her huge breast nipples and earlobes. What will the female teacher do to the vice principal's behavior that gradually escalates...?
