Naughty moves at the night club...

I was out dancing with a friend at a club and she was passing a man and when he passed him he pinched her breast. She retaliated with pinching his backside but afterwards she thought that he might have actually liked that instead of it being a retaliation or punishment. So, what did she do? She went back to find him among the crowd in the club and she pinched his Willy instead. He did not know what to do so he laughed a little and shaked his finger like saying no, no that was naughty. Well, all that was really crazy!  I do not know if it is necessary to mention, but I would never have had the guts to do it or believe it is an ok thing to do.
