My wife and I are quite happy together and we like to indulge each other in each other's fantasies occassionally so long as we are both sure it is nothing that we will regret later. For the last 2 years, we have had a really nice woman (about our age - late 30's) and her son, Keith living in the other unit of our duplex. Keith was17 when they moved in and my wife expressed to me that she thought he was a very handsome young man and I'm not afraid to admit that he was a good looking kid with an athletic build. He was sometimes a source of getting my wife turned on for love making. We never considered anything physical with him because of his age at the time and because he was a neighbor. But when we found out they were moving, I decided to do something about special for my wife. A couple of nights before they moved, we had a bbq dinner with our neighbors in our shared backyard. When we were winding down the night, my wife and Keith's mother both said goodnight and Keith and I shared a couple of beers and just talked about random things. I worked up the courage to tell Keith that my wife thought he was very sexy and his grin showed me that he was flattered. He admitted that he had sometimes checked out my wife's ass and fantasized about her. I asked if he would enjoy receiving oral sex from my wife and he did not hesitate to say yes. We went in I asked him to wait downstairs. I went up to our bedroom and my wife had not gone to sleep yet, she was having a soak in the hot tub and sipping on wine and I asked how much longer she would be and if she was in the mood. She was in the mood and would be out shortly. I had Keith come upstairs and strip naked and lie down in our bed. I stood by the bedroom door waiting for my wife to step out of the bathroom. When my wife stepped out and saw Keith naked on our bed, I could tell she liked what she saw. I said have fun and left the room. Keith came downstairs about 15 minutes later, looked at me, shook his head with a smile on his face and said goodnight. When I went upstairs I saw my wife laying on the bed with a very big smile as she licked what remained of Keith's cum off her lips. She thanked me and we had the best sex we had had in a few years.
