Mistress Dana wanted to make sure that this guy learned to do things the right way and more importantly, that he learned his place. She felt that he did not and that was not ok with her. So she turned him into a foot slave and she dominated him by forcing him to lick her feet, her soles as well as her socks before she warned him not to repeat his mistake.
Mistress Dana is not an easy person to please as this guy came to find out. This guy wanted to please her and he found it a hard thing to do. To make it easier for him, she told him what to do but he did not do it as well as she wanted him to do it. And as punishment, the mistress used her foot fetish to punish him. He had to lick her feet and even suck her toes to avoid being trampled.
