Tie her up

I think about it for a moment but then I realize, I want to see how much Doe gets off on domination. I have her strip her clothing, even the armor. I then take a couple of ropes that were being used to hang up tapestry and tie her up so that each of her limbs is tied to one of the four bed posts. Doe looks up at me when I am done. "What are you going to do to me sir?"

"Doe, you belong to me now, and I plan to claim you tonight, so that the whole world knows it. I'm going to implant my bastard seed in your naughty womb so that your country can see what happens when you dare to rebel against the crowns authority. I'm going to fuck you so hard that theirs no way you won't be a knocked up slut by the end of the night."

Doe looks up at you, her face a mixture of fear and arousal. "Well I suppose it was going to happen sooner or later. I am your rightful prisoner after all." You smile at her quiet submission and begin to undress.

This is the first time Doe has truly seen the girth of your cock. Doe looks at it apprehensively but you don't have time for that. You line it up and plunge in, the ropes restraining Doe from stopping you. (If she even wants to). You thrust in and out of her increasing in speed. Doe moans as you hit her cervix. You tell her all about how her stomach will swell with your bastard soon. Her breasts will grow and produce Mother's milk. And as soon as you give birth you'll knock her up again so her womb is never empty.

While you say all this you grab her cock and jerk it off for her. When you tell her your plans for her womb she cums all over you, and that sets you off. You bury your dick as close to her cervix as you can and shoot your life giving sperm against her cervix. You cum so much you're almost certain she's pregnant, but you can never be too sure.
