(28M) I unintentionally cucked my fuck-toy’s bf [MF]

I posted this to/r/dirtyconfessions but thought it might fit here as well. Let me know if there’s anything I can explain better or you have any similar stories! :)

A couple years ago I was in a dating grey area where I was seeing two girls at the same time and neither wanted to put a title on it, so I continued to see both. They were both well aware of each other, and essentially traded me back and forth from week to week or day to day depending on how their own relationships were going. One I would consider my gf, the other my fuck-toy, simply based on the politics of the relationships between us. The gf was a big fan of going on dates and staying overnight like a normal relationship, while the fuck-toy was more interested in sexting, meeting up to smoke, and quick booty calls. Ironically, the one I would consider my gf was the one more bound to her own relationship, and the fuck-toy the one who was more interested in a relationship with me – but could never make up her mind.
