RP, you might want to reread derby's post. She caulked it up to him being caught up in the moment....shit happens, bad luck, forgive and forget. This moment happened what 4-6 ft away from the sister and her husband ..2 sets of eyes 2 sets of hears. So close he could have been in a conversation with her or them or had eye contact with her the entire time to add to the thrill. Or tried to involve the fingeree in that same conversation with the sister and BIL...to really push her fantasy to the limit.
"The caught up in the moment" defense to me is as offensive as the disrespectful act itself. Its in effect calling you stupid... telling you a story as if you weren't there...didn't see the proximity of everyone ...don't know the layout of the room. Its spin ...and bullshit trust me I know guys like this.
