Several loads later.

You're not sure how long you two stay like this. The sounds of lewd gagging intertwine with the plapping of skin on rubberized skin and your own husky pants as you treat Asuka like the object you designed her to be. You cum hard and feel your load come out stronger and thicker than before, and yet you don't even soften a little after you cum. Asuka seems to notice as well, because she starts to add little flourishes to her own head bobbing when she realizes it won't be over in seconds.

Your balls churn and try to keep up. You cum again in a fraction of the time thanks to your post-orgasm sensitivity and Asuka's ramped-up actions.

You cum again.

And again.

And again.

And again.

Asuka groans and moans as her belly starts to distend beneath the cover of her dress. She shows a little resistance, and you fuck it out of her by moving so every time you buck your hips the back of her head slams into your bed. A few firm knocks and she's back to dutifully pleasing you, making you cum.

Again.

And again.

And again.

By the time you've had your fill, your body is shaking from overexertion. You feel like you're overheating, pulling back and mumbling a quick stop to Asuka's overwhelming cock-lust so you can actually breathe. Your cock pulses and aches with the aftershocks of dozens of orgasms, so sensitive that even the feeling of your own throbbing brings you dangerously close to get another orgasm.

In front of you, Asuka sits on the floor with a body completely warped by your actions. Her breasts and thighs are no longer her most prominent features, a massive, pregnant-looking stomach sitting prominently in her lap while cum still oozes from her mouth. Labored little noises bubble out of the sentient sex doll as she cradles her beachball-sized belly, barely even able to focus herself enough to look up at you with a strange mix of gratitude and defiance.

You've had your fun... do you snap her away?
