Sun, thank you for the reply!
As far as them playing at our pace, it makes a lot of sense, and we thought about that as well. That was one of the reasons why we/she asked what the boundaries were. Their may have been something said on our end as well to the effect of, "well, we aren't exactly sure how to proceed from this point..." This all after the hour of chat at their house.
Regarding the attraction level, we took it as a sign that since we were in three different locations with them, that there was an attraction. If not, we would have been more than fine with them ending the night, and us going home, because at the end of the day, we still get to go home with our partner!
We also understand what you said concerning bisexuality. If the other woman is not attracted though, I have to really question why she would initiate any sort of kissing, groping, and even straddling her in the strip club. Also, another sign that she is attracted. If there was none, we would much prefer honesty to a few hours of awkwardness. It won't hurt our feelings haha.
Again, thank you for writing. I hope none of this came across as argumentative, or that I'm discounting any of what you are saying. Just want it known that many of these things have come up in the conversations between Mrs. C and myself.
