Oh, thats a toughy. they are married...so meh. This is all your call sir.
See. I don't really get threesomes that much. I mean, I'd probably try it, but it's not on my "must do" list. I have trouble pleasing one chick, let alone two! Best case scenario...I please at least ONE of them. Worst case is we all have a bad night. Either way, not very good!
