To do it or not...
I have been with my husband for 13 years. He has always told me that he wants to do a 3 sum and I'm OK with it but we have not been able to find a drama free women. We'll 3 months ago I found out that he has been sexting with one and wants to do a 3 sum with her and I. We have a very healthy sex life and have always alternated being the one in charge. It would be hot to do it with a girl and she's pretty, but he wants me to be their sub and I feel weird about that and it's got me second guessing. Shouldn't it be the other way around where she is our sub?
You should pick out the girl, and make sure she's solely into casual sex under your terms. Don't let your husband pick. The truth is that he'll enjoy new pussy of any type. Make sure it works for you first.
I wouldn't do it with her. Find a woman who he hasn't developed a relationship with already. That is dangerous territory .
Sweetie probably the best thing is to give it a go just to get the ball rolling then when he is very interested advise him things are going to change just a little next time bet he and she does not worry.
Please let us know how you go ?
