Hmmm - more to say here after all this time.

Good girl - when he's pleased. And my usual response - "I want to be a good girl for you" pleases him also.
bella - sometimes when he says goodnight, and I adore this name.
bright eyes - rare, but special.
my given name or my first initial - when he wants me to pay particular attention.
girl - this reminds me of my place, and turns me on too.
jgirl or subbie - when he's gently teasing me, because he knows I hate that! Evil man.
Horny little slut - only once, but I have a feeling I'll hear it again...

There's more, but right now my brain is fogged up...
