My younger brother has always been a bit of a pervert. So, it's no surprise that whenever he visited us, he would openly lust over my gorgeous wife. She said he was harmless, but I could tell that she felt flattered by his attention. Last weekend, the three of us went out on the town and then returned to our house after we were all partied out. My brother and I plopped down in the family room to chill for a bit while my wife went off to change. As soon as she left, my brother started saying how lucky I was to have such a beautiful and sexy wife and how it had been several months since he and his wife had sex. A few minutes later, my wife came back in dressed in this black teddy and said she was going to bed. She looked so incredible that my brother just stared at her and seemed at a loss for words. After our little discussion, I was feeling a bit sorry for him. So, I turned to my wife and told her that it was cruel of her to be such a tease. She got a little grin on her face and replied that if I came to bed now she would prove that she wasn't a tease. I said no, that I didn't mean she was a tease to me. I meant that she was torturing my brother. She got this surprised look on her face. When she looked over at him, she could see what a state he was in. She started to apologize and said she didn't mean to, but I interrupted and said that words weren't going to take care of the problem she had created. She looked at me quizzically and said, "You mean you want me to take care of it?" I shook my head yes. So, she walked over to where he sat. For the next hour, I just sat back and watched the two of them have really intense sex. Now, about twice a month, my brother stays for the night and I get to watch the two of them together.
