Hi, me and my gf of 8 years have always been talking on and off about her being with another guy since forever, not in a proper cuckolding/humiliating way, but the thought of sharing her turns me on so much and it does the same for her.

Recently one of my friends and coworkers have gotten a divorce and we talked a bit about it and wanted to give him a confidence boost as well as have some fun ourselves. So I said to him that it would be okay for him to basically sext my gf and she would send him nudes. It's been amazing, so insanely hot and she's been so horny and we've fucked like rabbits. She's been incredibly sweet to me and at every corner had made me feel secure and safe. If anything has been even the slightest bit uncomfortable for me, she's given me all the love and attention I could dream of.

From the beginning she made it clear to my friend that nothing would happen and it was only fantasy. But at one point, during their sexting he said that he'd want her for himself. That didn't quite sit right with us, but we never really set any boundaries for him except that it's only fantasy and not going to happen. We both told him that it was over the line and stopped the sexting and nudes, he expressed that it was just part of the fantasy for him and I get that, he was definitely lost in the sauce right then.

But the thing is it was so insanely hot, my gf had been so sweet and supportive the whole way and I genuinely would consider letting him have sex with her. But I'm not sure if we should set some proper boundaries and resume the sexting (not sure he even wants to at this point), or just enjoy the thing as it was.

Have any of you been in this situation? Or do any of you have any piece of advice as how to go forward? I'd be interested in just hearing your thoughts on this as well.
