I had a long term gf who I wanted to cuck me. We’d done a lot and she was good, but I needed for her to experience a big dick and we all know the most likely candidates. Definitely not the stereotypical snowbunny, but she had these wide hips and a bubble butt that got attention. I got drunk one night and finally told her what I wanted. First she made me tell her how I thought we were going to make it happen. Then she got mad that I ever considered that she might go along with it. Finally, she put the idea to rest because she considered that cheating and she wasn’t changing her stance on it.
Then about 7 months later she cheated on me with a Mexican while she was on a trip. I’ll never forgive myself for not trying harder to convince her to try.
