I'm wouldn't quite say that. Amy has a technique with her tongue which given time, will make you pop. Key is to let her work her magic. If your trying to pump or influence her, then it's teeth for you lol. Michelle flat out is a bit of a biter.
I give her credit, she was game for a proper face fuck when I seen her. Standing and lying on the edge of the bed. Not much stamina though which rules out the possibility of cumming from Oral with Michelle.
