Girlfriend admitted that she wants more than 2 guys, now I can´t stop thinking about it...

I´ve been dating my girlfriend for 6 months now, one night we were drunk and ended up talking about our fantasies. To get to the point, she admitted that she loves the idea of two or more guys worshipping her together...

I was intrigued to hear, why she loves the idea so much. Hearing her talk about it and seeing the look in her eyes when she did, turned me on so much in the moment, that it ended up being one of the best nights of sex either one of us has ever had. Role playing with her about another guy or two being there with us.

Now I can´t stop thinking about it, I don´t want to bring it up to give her false hope and I don´t want to risk our relationship as a result. But also cant get the thought of her sandwiched between me and another guy out of my mind...
