Mistress BlackDiamoond was pissed when this guy promised her something and did not do it. She was pissed that he lied to her and gave her a promise he could not fulfill. As part of his punishment, the mistress forced the guy to lick her ass as she facesat on him. He was degraded and humiliated and he regretted lying to her. She did not care about the promise anymore. She only wanted to teach him a lesson.
