Missy Van Licks needed to slap this loser and at the same time she needed to show her friends how it was done. So she decided to do both of them at the same time and that is exactly how it all happened. She showed them how to do it and she then let them all have a go at him and they did it without caring what they all felt.
This guy thought that his advanced age was a license for him to do whatever he wanted and to mess people and inconvenience them at will. Missy Van Licks was not one of those who were going to sit back and let him do it. So she used her faceslapping fetish to deal with him and she cruelly tortured him for the sake of teaching him never to do what he had done.
