The guy says that his hotwife is always feeling horny, everyday is harder to please her in bed and 9 years of marriage doesn't help at all. She told him that she fantasizes with his brother, mainly because he's single and likes to tell his sexual adventures at our dinner table when he comes to visit us. On one of those dinners he dropped the question, without even talk with her, if he would like to fuck his wife. They were all a bit drunk, but no one seemed shocked or surprised, only started to laugh. The next time his brother came to dinner, she made things happen with her husband's approval.
