It was my fiance cheating on me. We had been living together for several years and our sex life had dropped right off. I wasn't bothered because I was busy with work at the time to support us both and I hadn't considered cheating until a neighbour told me she saw another guy coming over to our house. I'm not confrontational so I set up a cam in our bedroom to get proof rather than talk to her, and after a couple of days I managed to get a recording of her fucking this other guy. Again I avoided confronting her but I was absolutely devastated and treated her coldly for awhile.
I found myself turning it over in my head to the point where I was getting hard to it. I set up a few more cams and eventually started jerking off to it. My insecurity was huge, this guy was more masculine than me, his cock was way bigger, his balls were way bigger, he was taller and more muscular, and there was also the racial bit because he was black (me and my fiance are white and she said she'd never date a black guy). It was a powerful mix of humiliation and submission, working hard and supporting the women I loved while imagining and watching her strip all her clothes off and lie naked on our bed, my wife's legs spread open and his larger, darker cock pushed up inside her petite white body while at the same time she wasn't fucking me. She stopped eventually and I still ended up marrying her but I never told her I knew she cheated on me. I've never talked about cuckolding and our marriage is very vanilla. None of it makes sense to me, I don't know why I'd be aroused by cheating or the racial bit.
FUCK MY WIFE!
