Ok, my gf is extremely interested in trying a FFM 3some, I also would love to help her experience this fantasy of hers and mine. She has been with a girl once before, when she was much younger, and she loved it. She enjoys performing orally on another woman, and I would love to do it with her and watch her do it. The problem is, I've always thought that a 3some is a good way to end a good thing, and I care/love this girl deeply. We've discussed marriage in the past, and my thing (being formerly married) is if I get married again, I want it to last. I think that this girl is the love of my life, and I'm scared of....idk what. Partly I'm scared I guess that she will forget that I'm there, or that afterwords she will enjoy it SO much that sex with only me will simply not be enough. Or that it will somehow taint the way that we look at each other since we will have technically "cheated" in front of each other. For myself and her when we've discussed it, I only have a few rules, and they are: #1. Neither I nor she cums with the 3rd party. #2. No kissing between she and I with the 3rd party. #3. We should do this with a non-friend. Her best friend (the girl she was with before) would do this anytime, we are both quite sure, what do we do? As of now, we have decided to leave it in the realm of fantasy and dirty talk during our lovemaking, but we do both think about it quite alot. I've told her that if she marries me I dont want her to look back after our 50th wedding annv. and have ANY regrets. And if we DONT do this, will this BE a regret? BAH! HELP!
