Mistress Lea did not want to use her ass or her tits to tease this guy. She knew he was a car buff and so she used her sexy feet and her pedal pumping to tease him. She would do so and then make naughty faces at him and he got what she was communicating and he was turned the fuck on. But mistress Lea teased and denied the poor guy.
Mistress Luna wanted to send her slave a message and she used pedal pumping to do it. The mistress took a video of how rough she pedal pumped her car and she got him to see it. She then told him that was how she was going to crush his balls and his face if he did not change and do things the way she instructed him. He was scared and he did things her way.
