Mistress Abbie did not like how late this guy was and for her, that was not something she was going to excuse. She had to make sure that there were changes and that is why she did what she had to do. She cruelly turned the guy into a foot slave and he had to lick her muddy soles. He had to do it or have his balls crushed painfully.
Mistress Abbie needed to do something to entertain herself. She chose to do it by cruelly trampling this guy. She did not care about anything else other than having fun at the expense of this loser. The guy did not know why she was doing to him what she had chosen to do to him. He was shocked by what she did but he couldn't say anything about it. She just trampled him until she got bored of it.
