Mistress Polina did not need to get up from where she was seated in order to give this loser jerk off instructions. That is because she did not want him to touch her and she was not really trying to entertain him but rather entertain herself at his expense. So she sat back and she gave him instructions which he had to follow and he had no choice but to do it.
Mistress Ellie had a score to settle with this guy so she used her hot body to get him to think that she did not have any issue with him. She acted like she was into him and she wanted him to fuck her brains out. Seeing as she is an extremely attractive mistress, the guy could not resist her. But as they went on flirting, she turned him into her human atm and she financially dominated him.
