My wife Liz and I have been married for 12 years. Liz is a very pretty brunette, 5'10" tall, long brown hair, brown eyes, 145#, beautiful legs and ass, and nice firm B+ or C tits. I am 5 years older than her, I'm 45 and she's 40. I'm 6'1", brown hair, blue eyes, 185#. After 3 or 4 years of marriage, I began encouraging my wife to consider trying some new sexual experiences. Initially, I wanted her to agree to a FMF but I figured out very quickly that was never going to happen. So, I suggested another guy for her. Since I am 100% straight, we would only be taking care of her, but she still refused. Her reason was that she is only attracted to me so she couldn't enjoy sex with anyone else. I pointed out that she had enjoyed sex with other men before we met, but she maintained that she couldn't ever be interested in sex with someone else. I still didn't believe it, but she refused to agree so I dropped it for the time being.
We have several friends that we get together with every few weeks, either at our house, theirs, or a club somewhere. 2 couples, and 3 single guys. The single guys are Ricky, David, and Greg. Ricky is divorced, David is separated, and Greg has never been married. Greg is also black. I've noticed that all 3 like flirting with Liz, especially Ricky, and she's never complained about it. He spends more time hanging around Liz than he does the rest of us. He's always teasing her and making her laugh. I asked her a couple of times about being attracted to Ricky, Greg or David, but she denied it. I even joked with her that black men are supposed to have very large cocks, but she showed no interest. As it turned out, it was actually Ricky who has the extra large dick! We had a pool party at our house one weekend that ended up in several people skinny dipping, including Ricky, Greg, me and David as well as a few of the couples invited. Liz did not, but she wasn't bothered by it. It was then everyone saw just how well endowed Ricky is!
Ricky is about 6' tall, long brown hair, about 10 years older than I am, and loves being single. I was quite surprised to find to find out he also has a cock that has to be over 9 1/2" and quite thick. Mine isn't small, but probably 7 1/2" and no where near as thick, but she's always enjoyed sex. I asked Liz if she had noticed Ricky's dick and she admitted she had. Her response was "It looks too large to be honest. I'm not sure why any woman would want to have that inside her."
A couple of weeks later, Ricky and I went hunting at his deer lease. We were there for 3 nights, he has a camper there so we could stay at the site. While we were there, I brought up his flirting with Liz. He admitted that he had always been attracted to her. He had recently walked in on her when she was changing. Once he saw her naked, he had been dying for more. I told him a bit about what I had discussed with her, along with her response. He and I agreed that was bullshit. It was then I came up with a plan that I set in motion a few months later.
