Cassy's pause on slave's balls

Description: The slave sits next to the bench and puts his sensitive parts on it. Cassy notices it and figures out a good way to enjoy herself torturing him. She stands on the bench and she tramples on the slave's cock and balls wearing her nice sneakers. In the meantime she uses his mouth as an ashtray. She even extinguishes her stub on his tongue and makes him swallow everyting.
