My wife & I have been married for 7 years but dated for 5 before that. She is 5'2 34 C and 110 lbs, and a former "Miss" winner from the state we live in. We both had a mutual black friend from before we met. He is still single, former college football player from our U. My wife & I moved to another state right after we married. Our Friend ended up getting a job and moved to our city 2 yrs later. We have been hanging out a lot since them, lots of double dates, but he seams to have a different GF after every month or 2. He lives less than a 1/2 mile away. Over the last 5 years, it seams sex comes up more and more often. It started our as we talked about one really extremely hot GF, that we happen to find out was married, and her husband knew they were going out and spending the night together. As the topic got richer, he said he had made a video and her husband let him keep it and even told him to show it to his friends! My wife & I had occasionally watched X rated videos together, but she complained they were too fake and they guys & girls didn't really look like that. Anyway after stopping by his apartment after clubbing because my wife had to go, and it was a cold walk home, he told us about the video and asked if we wanted to watch. My wife said sure (probably because she was feeling no pain). She hadn't considered she would be seeing him nude and fucking. After it started she got embarrassed, but didn't say anything until we left. The married ladies husband had actually filmed the video and even had set up 2 more cameras. As soon as we got home she attacked me, gave me a great BJ and even rode me until I came. You have to understand she had not ever given me a good BJs or it got on top before that. A couple of weeks later she asked him to bring the video to our house. We had a BBQ and watched our school's football game, then watched the video. After he left we had great sex, and she made several comments about our friend's size and some of the moves he made, and how long he lasted. She suggested I ask him how he lasts so long. This led to conversation the next time he came over. He also brought some more videos he had made, but most were not the same lady. He left them at our house that week. In fact a lot of the videos were from when we were in college, and my wife & I recognized a lot of the girls (mostly white) and they were married friends. Based upon the background rooms of where the videos were made, several of the girls were married, cheating. Even several of the recent videos were of married women (wedding rings were everywhere). The next weekend we all went up to our apartment, (after clubbing) and my wife put on a video. As we all watched, she started making comments about the girls our friend was banging, (a lot of Fast forwarding by my wife) then asked him what was going on? He told us it started in college after a mutual friend invited him to have a 3 some with is wife. That wife told another wife, and it spread from there. Then he ran across one of the couples he had done right after moving to town. He told us we would not believe how many married ladies he has had sex with. Sometimes the husband is there, sometimes he listens over the phone, some times a video, sometimes just a couple of pictures of his BBC in the wife's pussy and mouth and cum on her body. Sex was always hot after he left. A couple of years ago while we were hot into sex talk with our friend and watching his latest video my wife asked if his dick was really that big or did it just look bigger on TV? That lead to him showing her his raging hard on, and she even touched it, but that was as far as it went, that night. After that, every time we all watch one of his videos he offers his services to my wife. The first time he did it I protested, but my wife immediately came back with the comment, that she would decided "When and If" she would take him up on the offer. Over the last 2 years, it has been a hot topic in our bedroom during sex talk. For the last year, she has even been wearing more daring cloths when he comes over and has been flirting with him with suggestive comments as well. Before this year, she always wore a bra when anyone came over. For the last 5 months, she doesn't wear a bra when he comes around, the last month she stopped wearing panties under her shorts. Two weekend ago she wore a pair of relatively short jean cut offs, that were not tight and no panties, with a linen button up front shirt, that when she leaned over you could see her breast fully. I watched closely, she did NOT lean over to give him a look or spread her legs, but he did take notice and made the comment how sexy her cloths were and how sexy she looked. Last weekend I did catch her leaning over and letting him see her breast, several times. She also was putting her hand on my pants leg close to my balls while she was looking over me at him. When he looked our way she smiled raised one eye brow and winked. He immediately offered his services (in a joking way, but I could tell he was dead serious). She replied, that she would seriously consider it, but she didn't think her husband could handle it, so maybe not right now. He looked at me and said, I promise I will take good care of her and she will enjoy every second of it. I said "Hell No". So my wife said "I guess maybe later." After he left, my wife was a wild woman in bed. She was talking about how she wanted me to let him fuck the shit out of her for her birthday present. Her birthday is in 2 weeks. I told her no way. Every night since then, she has been pushing hard for a yes from me. Last night sen even told me she would give me a BJ until I came, I said no, so she upped the annie and said she would let me cum in her mouth and swallow, and even let me fuck her in her virgin ass. She even through in a what if we had a 4 sum and swapped. I'm still saying no, but I'm not sure how long I can hold out. I think she has decided that she is going to have him do her for her birthday. Even if I don't agree. Then beg for forgiveness, because she knows I love her too much to let her go. I'm about to the point to tell her OK, but just once, because if let her do it she can enjoy without any guilt.
