I have to agree.... once they get close to an orgasm, it's amazing what words come out of their mouths as they desperately try to go over the edge. It's especially exciting to watch when the subject is a prissy & snobby upper crust-type, who has abandoned all sense of propriety and is embarrassingly caught grinding her wet cunt onto a huge black cock.
