Maybe everyone was boozed up to some degree and that factored in all of your decisions...it's not really *that* big a deal, yet it was wrong and you should definitely tell her. Depending on what type of person she is she might get pretty pissed, she might be pretty understanding. Tell her you were boozed up some (?) and made a dumb decision.
But I do hope she does still someday give you total uncontrolled swinger pleasure cuz whatever the heck that is I want to hear the details!!
