Crimson has one of the prettiest faces and will do dirty talk if you're into it. Also great service. One my fave.
Rylan and Jocylin at IF mention kink included in their standard rate, so they likely partake in dirty talk.
Olivia at IF has one of the prettiest faces, small breasts, and lists dirty talk as an included service. Pretties face for me though is Iris at IF, who also just has a mouthful. I don't know about dirty talk though. Also to consider is Keiko at IF. She has nice A cups.I assume she is good a dirty talke as many seek her for dom services.
