I've had a cuckolding fetish since I was young. It all started when the girl I liked in high school started dating a friend, and I heard some vivid stories from him. The more I love my girlfriend now, the more I think about whether her face will change if she has sex with another woman, and what kind of indecent moaning sounds she will make, and I'm going to ejaculate just by thinking about it. I couldn't stand it anymore... She's such a good woman. If they can fuck her, my friends will immediately latch onto her. Sorry for being such a shitty boyfriend. But I love you.
