Degraded Muddy Boot Licker

Mistress Cybill and Mina make an incredibly cruel combination, they both enjoy seeing slaves suffer for their amusement. Their stiletto boots are covered with mud and filth, perfect for degrading a slave with. The slave is ordered on his knees with his mouth open and tongue out, the ladies take turns wiping the disgusting from their boots into his mouth. They order he lick their boots clean, they ladies laugh at as he chokes on the grim and mud from the bottoms of their boots. When his tongue is completely black with filth they just spit into his mouth and tell him to keep licking. He chokes and gags on the mud when the Mistresses just laugh at his expense.
