Mistress Nica had beef with this couple and she did not want them to do to someone else what they had done to her. So she made them both kneel down and besides using them as her human ashtrays, the mistress also trampled them and also spat into their mouths. She had them beg her before she felt it was ok to stop what she was doing and let them go.
This girl was a slut and she tried to have a threesome with mistresses Valeria and Selena but they did not feel her vibe. She tried to insist but they did not take it kindly so they humiliated her to send a message. She was forced to lick their feet, lick their socks and even chew them before they trampled her. She licked their feet expertly and that is why they let her go.
