So, this idea/fantasy I have, revolves around taking a girl, my girl, my little pet, and converting all of our sex over to anal, be it all at once or gradually.

Or maybe that's just how I take her for her first time, and every time beyond that one.

Even if it hurts, even though I'm rough and abuse her delicate, little hole, she does it. She obeys me because she belongs to me, her body is mine to use how I want.

Maybe she's really worried about the idea, at first, but I don't give her a choice. Maybe I hold her down and force my cock into her ass, just taking what's mine. Maybe she squirms and whines and begs me to take it out, then slowly realized she likes if. Or maybe she's a naughty little masochist and she's plenty eager to give up that tight hole.

And there isn't a chance I pull out, no matter how she responds. I'm going to fuck that hole, choke her, slap her, hold her down and pull her hair, then I'm going to cum deep inside her, and that's when she'll know she did good.

Afterwards, I'd probably just put a plug in her, that way she keeps it all in her. She'd know better than to waste it, anyways, but a little tail plug to help keep it in wouldn't hurt.

We'd do this a few times a day, gradually getting her used to her ass being a cocksleeve for her master. She wouldn't get any forewarning, though, just the constant, looming idea that, at any moment, I could grab her and invade her tight hole, whenever I like.
