Erina put a human couchside rug in front of her couch and desperately want to test it. With her flat boots she tramples all over it. She starts at the legs, walks over the waist to the belly and chest and finally ends up with her boots in the face. Arrived here she orders the human rug to take off her boots so she can trample him in between in her smelly white socks, before the rug will take off those as well. Then the procedure continue with bare feet. The mistress tramples all over the human rug again and even jumping on it.
