Miss July and her slave are having fun, she has Roller-skates at her feet and want to dance, but he is provocating her, so she fights a little bit with him, until he is on the floor on his back.
Now she has a dancefloor for her roller-skate-dance... her slave's body and face.
Again Miss July shows, that she can trample her slave with every thing, it doesn't matter how painful it is.
