Mistress Kate is introducing Mistress Emma to her slave and wants to show her how to trample her slave. They both climb on him using their full weight as they jump and kick him, Emma then shoves her feet in his face forcing him to smell them. These foot femdoms continue trampling as he cries out in pain because they have no care for their slave as he lies under their feet.
This leashed slave is Maggie, who loves trampling and foot femdom just as much as her mistress, Emily, does. With Maggie bound in place and on a leash, Emily subjects her to stomach trampling and breath play, humiliating her as she jumps up and down on her tight little stomach. Stomach standing doesn't get much hotter than this, especially when the two people involved are such beautiful women.
