Mistress Erina uses her slave as a human carpet, as she wipes her flat boots all over his half-naked body. His skin gets hurt as the rough soles of her shoes scratch and squeeze it, especially when she steps on his face with her boots. Now, she orders the slave to take off her boots, to trample him for a short time with her smelly white socks, before she lets him take off those socks as well and continues trampling and jumping on her human carpet with her bare feet.
