Mistress Delvia and her roommate are bbw mistresses. The mistresses were amused at the level of interest that the their randy neighbor had in them. The mistresses felt that they had to find a way to humiliate him and take advantage of his sexual excitement. That is how he found himself licking her ass as well as smelling it too. They then facesat on him before they chased him from their house back to his own.
Mistress Delvia does not like rude people and since this guy was one, she had to make sure that she dominated and humiliated him as cruelly as she was able to. She smothered him with her BBW body and even sought the help of her friend in smothering him until he nearly shit himself. The guy was never rude again to anyone after what these bbw mistresses did to him.
