Sounds like she is more interested in you and also suddenly becomes a little shy. Umm. A quick kiss and feel in the bathroom is hot, but you both need to go some place where you are more at ease and don't have to worry about anyone else. (althought the excitement of doing something naughty in public is probably a turn on for both of you). But you should let your husband join. You may want the same rules I have used. That it is for you. You are the one in the middle and both the woman and the man are there for you. Later if you girls decide you can have him together. But her lips and his are there to seduce you. I think that is more of the type of three some she really wants. Believe me it still be a turn on for both of you and her too I bet.
