Improve her other hole

You take your time with Maria's sleeping body. You want to be much more precise than you were when you inflated Stacey's tits.

It takes you hours, and many breaks and reversals, but at the end of it Maria looks like the Playboy centerfold version of herself. Better, even - Playboy wishes they could book a model this fucking hot, one who combines a slim, soft body with incredible beyond-F-cup tits and an ass and hips that a fertility goddess would envy. The challenge wasn't making her the woman of your horny imagination, but bringing her back from the brink of cartoonishness, of making her body look like something that could be natural.

But you did it. Content with your work, at last, you add the finishing touch you promised.

NUMB AND SEALED PUSSY

You start to finger her, and in a period of a few seconds you feel her vagina grow smaller and smaller until it forces your finger out. Her lips and clit are still visible, but her body doesn't stir as you massage them.

The thrill of power over Maria courses through you. She'd given you the power to shape her, out of some submissive impulse that already existed inside her before your marker had touched her. Now you'd literally taken away the center of her pleasure. She was one step closer to being your perfect plaything.

But you wanted to do more. If you were locking away her pussy more thoroughly than any chastity belt, you'd need to make it up in other ways.

You move down her divine body and massage her ludicrously plump ass and pry her cheeks apart. near her puckered asshole you write

NEVER SORE

ALWAYS CLEAN

CRAVES FULLNESS

And then, because why the hell not

ANAL CLIT

The little nub grows before your eyes at the top of her asshole.

You position yourself behind her still sleeping, if slightly more fitfully, form and lube her up with just a little spit. Then you plunge your cock into her ass. She's virgin-tight, and grips you hard. She starts to moan and writhe unconsciously. You cross out DROWSY with the marker and she's suddenly awake to you pounding her remodeled asshole.

"Oh my god!" she says in shock, just trying to orient herself, then in sudden ecstatic pleasure, "OH MY GOD!"
