Wife Has A New Boyfriend. My wife spent the afternoon with her new boy

My wife spent the afternoon with her new boyfriend, the artist. We live in an area with lots of hippies and artistic types. The artist is 42 years old, divoriced three times and know to seduce women. Anyway, she has been at his studio twice before. She tells me all about her visits, but they have only flirted until today. He is going to take pictures of her to use as a model for a piece of sculpture. She left at 4 pm and returned at 7. She made some noise about being so long and took off for the shower. I'll get the details later

She went over to his studio again this afternoon. She left at 3 pm and came back home around 6. She told me that she was posing nude for him, but it was ok because it was art.
