For me, there was a couple in our neighborhood that we used to hang out with and party a bit. We were all the same age and our ******* did a lot of activities together so we would share duties, taking them to games, school functions etc. My wife always mentioned how good looking Jack (he is a white guy) was and being younger I was pretty jealous and would usually just change the subject and try not to think about it too much. Finally one night when we were making love, she must have been fantasizing pretty good because as I slid my 4 inches into her, she screamed out, "Oh Jack!! that feels soo good.."
In the moment I ignored it (but was pretty hurt) and she denied it. Not wanting to ruin the rest of the evening I let it go, it but it opened my eyes to the fact that my wife had fantasies of other men while we have sex. Eventually I realized she was super horny that night and even though it may not of been because of me, I benefited greatly from her imagination! Over time it turned me on to think of her, thinking of others and I realized it would be better to stoke the fires of her imagination. So through videos and introducing sex toys into our bed, I realized that both she and I enjoyed watching white women being taken by strong good looking Black men, and the thought of sharing her began to occupy my mind constantly. I never really thought much about the cuckold part of all this, I would picture her taking me and another with both of us pleasuring her greatly. Fast forward a few years and we were enjoying a Janet video where she was with 2 very well hung Black men and my wife was really into it, focusing on the fact that Janet's husband must be a very good man to sit by while his wife is being pleasured by 2 men. She asked if I would be able to handle it and simply just watch her with 2 very hung Black men. I was stunned but realized if that was what she wanted me to do then I would abide by her wishes! The results and how my wife reacted to me saying I would do it for her, burned deeply into my imagination and it has evolved to where we both verbalize our fantasy with each other and she loves the fact that I am more than willing to be her cuckold. Now if we could just get past the fantasy part and actually have an experience that would be fantastic!!
Anyhow, long story i know but that is basically how I became a cuck! On paper anyhow...
