Making her deepthroat you seems fitting enough.

"On your knees, bitch,” you order her.

Nodding calmly, she kneels in front of you, parting her lips in anticipation of what you're going to ask her to do. No doubt she thinks she can just spend a little while blowing you and then get away with skirting your commands. Unfortunately, she's got another thing coming. You’re going to use this to break her to your will, just like she would have done to you if your positions were reversed.

Grinning, you grab her hair and **** your massive shaft into Lady Grace’s waiting mouth until you’re balls-deep in her throat. She manages not to **** on your girth, so you start thrusting powerfully, pistoning your cock between her lips. She’s not giving you a blowjob; you’re fucking her face—and loving it.

Your balls slap against her elegant, narrow chin with every thrust as the warm wetness of her mouth and throat sends shivers of pleasure rushing up from your groin.

The erotic sensation combines with Lady Grace’s total submission for a powerful effect on you, and you can feel your balls tighten as your orgasm begins to build. The only question now is: what to do with it?
