25m I’ve became a cuck because of threesome

Hey, I’m a 25-year-old guy 🇵🇱 and I’ve been with my girlfriend for 5 years :). For some time now, we’ve been exploring threesomes. We’ve done it 3 times so far.

In everyday life, I’m a confident person and I know my worth. But something that has really started turning me on during these threesomes is that, in a way, it’s a light form of cuckolding. The guy we meet is much more dominant than I am, and I also struggle with premature ejaculation. It usually ends up with me being on the sidelines and supporting my girlfriend — like holding her hand during it, or kissing and cuddling together. I’m only actively involved in the sex for a relatively short time.

But seeing my girlfriend completely let go during a threesome after this guy starts dominating her is incredible. I feel like she behaves completely differently with him than she does with me. Sometimes it feels like she forgets about me while it’s happening. She says she absolutely loves it. I didn’t expect it, but I’m really turned on by it too.
