Jane has her slave trapped in the floor with a hole for his face.
His face is upturned and he cannot move or turn away... he has to take what jane dishes out ;-)
While she stands over him, she teases him with her bare foot and let him know, that she will put on her shoes and walk on his face
She sits down on his belly, takes her shoes on places them on the face for giving him the idea, how it will be under them.
Then she stands up teases him with stepping lightly on the face and walking around.
With every steps she places her foot more on the face, and increases the painful pressure of the hard shoes...
Now your are a piece of the floor and you should feel like the floor!!!
