Correct her techniques with orders

You begin ordering her to do things more to your liking and with each order she seems to get more and more excited, and each time she says “yes sir” you see a little flash of something in her eyes.

She’s now fucking you like she’s known your body for years, and stroking your cock better than even you do.

“I’d there anything else I can do for you sir? I’ll do whatever you tell me to do. Just say the word. I’m yours.” She says while panting in excitement.
