Here's another trick....
Get her to tell you a sex fantasy while you're playing.
Encourage her to talk. "Then what happened?"
Every chick has a fantasy. What are hers?

Also try leading her.
"Do you want me to fuck you?"
Tease her clit with your cock.
She'll say "yes"
And you'll say "Yes, what...?"
Dont fuck her until she says the whole thing.

(Granted those words may not be too vulgar....customize)

You may have to do this a few times to get her retrained, but it works.

She may never be a noise maker...so accept that....but I find sex talk hot when we are doing it.
