Mistress Christina slides out of Her black thong and face sits slave squirrel balls. Her well-manicured fingers tie Her thong tight around his balls and she spanks them, making him squeal into Her ass. He is sniffing Her womanhood through the nylon and this is making him excited but Her palm slapping his balls is really hurting him. She takes his cock into Her mouth and sucks hard, making him groan in pleasure. She resumes spanking his balls, slapping them over and over until he is screaming into Her ass and using Her expert oral skills to keep him excited. She knows a man can take a lot more distress when he is aroused so She cycles the pleasure and distress.
