Wife With Buddy

A few years ago my wife and I had a few threesomes. My wife had sex with a few guys and told me about it afterwards which resulted in great sex between us. We talked about a threesome and finally while on a business trip together with a buddy ofmine it happened. We were very comfortable with each other, it was great and led to more. One night while he and I were traveling I asked him if he and my wife were ever alone together which she hadn't told me about but said some things that made me wonder. He admitted they met twice, the first time she tied his hands and did what she wanted. The next time it was his turn, they met at a house she was watching for friends, got naked and he face fucked her while she hung her head over the bed, a fantasy of his. The her turned her over and entered from behind fucking her until he pulled out and sprayed cum on her ass and back, another fantasy. I might be wierd but get off over my wife with other guys and was rock hard hearing the story. I said sorry but I have to do something with this hardon, he said go ahead so I jerked off til I shit a huge load while he watched.
