I am an unusual man, but you wouldn't know it on sight. Probably not many men have had such an urge to see their wife having sex with another man, especially not a man as outwardly normal and 'vanilla' as I. But our relationship became what it is because I worked hard for it to become polyandrous.
It all started for me long ago. Everybody has a kink, I believe. Mine is an inexplicable sexual weakness for erotica written with cuckoldry as a theme. I couldn't explain why that is true and wouldn't even attempt to try, in part because I feel that to try to quantify the urge is in some ways tantamount to apologizing for it. Either people understand, in which case no explanation is necessary, or they don't (and never will). Strictly speaking, I didn't want a purely cuckolded relationship with my wife because I didn't want to be deprived of her myself. But there was something that erotically stirred me at the thought of watching Cathleen with another man, especially a black man.
Cathleen was just 18 when we met, and I was 28. She has a curvy figure, with long brunet hair and pale white skin. Even though she was younger than I she was fairly sexually active before we met, and didn't seem to feel as though she had lost out by marrying at 20.
In the last year I had begun to try to get her interested in a menage Γ₯ trio with another man. She was resistant for some time, thinking that my request signaled a lack in our relationship. I downloaded erotic stories with a cuckold themes from the internet and left them on the computer for her to find. I started bringing home more interracial porn and sharing it with her, dropping the occasional comment on how much it turned me on to see white women with black men. Eventually she came to see that my fantasy was not a bad thing for her at all. After a few months she began to get into the idea as a fantasy, and started to talk dirty to me during sex about imaginary lovers. My immediate physical reaction was for my cock to throb get harder within her. I flipped her over and took her with renewed passion. She clearly enjoyed the reaction and started pouring it on. Her talk became much more explicit and coarser. I couldn't help myself any longer and came hard inside her. Rather than let the moment pass, I scooted down between her legs and started to lick her with abandon, crying out that her lover's cum tasted good in her pussy. Cathy climbed up onto her knees and proceeded to ride my mouth. Her dirty chatter continued as I pleasured her to completion several times until her legs gave out.
The next morning I brought her breakfast in bed, and generally spoiled her for the day. We didn't talk about the night before. But our lovemaking had graduated to a new thing, and we started to increasingly include role playing like that night. After a month she started to want to take the fantasy deeper, but not actually physically fulfill it. However, she insisted that she have the right to experiment on her own as to how to accomplish the next step. I heartily agreed, feeling that she needed to be comfortable and that couldn't happen with me hanging over her every move.
