It seems that being unfaithful is the new fashion these days. Nancy Ace has gone on vacation with her husband to a ski resort. He doesn't seem too keen on the idea of going skiing, so he stays at the hotel while his wife goes off with a personal instructor to enjoy the snow. Then what happens happens. You know what I mean. When Nancy gets back to the hotel, she doesn't go straight to her husband's room, but to the instructor's room. And they fuck, of course.
