Recently?

Maximus stared down at Nancy for a few seconds. The sight of her made his cock throb, even having just filled her with so much cum she looked slightly pregnant.

"Well..."

Should he confirm what she clearly thought? Did he have a choice?

Hell, he didn't have a choice. Nancy had a stunning figure now, and as another 5 seconds of silence passed, he watched what little remained of her former obese self seemingly absorb into her. Her face and neck slimmed down even more, her abdomen gaining tone (and displaying the bulge of her overfilled stomach more clearly), and somehow her hips/legs/thighs also toning up yet remaining soft and inviting. Her tits and ass grew slightly more pronounced as well, and her arms got the same treatment as her legs.

In short, her form was perfecting towards his fantasy ideal as he watched.

Yep, ****.

"Well....About 2 days ago, I awoke to the aftermath of a wet dream, jizz all over myself. Then all this started to happen. I don't know how it works really, but I have some theories."

"Two of which are, the results seem to closely match my sexual fantasies, and that if someone ingests my cum, it works faster. It appears we just confirmed that. I'm starting to think it works better if it's fresh, too..."

"Frankly, I'm not sure where my fantasies end and reality begins anymore, and that line seems to be shifting every time someone comes in contact with my semen."

Nancy looked at down at herself.

"So it seems, but we really should test it more....just to be sure."

... ... ...

"What did you have in mind?"

"Well...*vague wave at stomach*...it appears we share an interest in vast amounts of cum. I've always wanted to have my cunt filled with so much I can't move. So much jizz inside me I can only bounce on the waterbed that is my filled womb. I must have masturbated thousands of times to that fantasy, but it's beyond the capacity of normal humans."

"You though...if you're really changing reality I want in on it. Maybe I can influence your fantasies and get my wish...fulfilled."

"Pun absolutely intended."

Maximus's balls gurgled loudly as they grew visibly in size.

"I'm going to take that as agreement." Nancy lowered herself to all fours and turned around, presenting her massive yet insanely perfect ass to him, the hem of her schoolgirl costume fluttering above and around it like the petals of some lewd flower.

She waggled it in invitation.

An unthinking growl of desire left him as he dropped to his knees behind her, the shaft of his huge cock slapping down on the right globe of her ass.

The mesmerizing resulting motions inspired him to grab his cock and slap the other globe too, alternating a few times as he got lost in the rippling masses of perfect flesh.

An audible sound of liquid hitting the kitchen tiles brought him back to awareness. It appeared Nancy was extremely ready for this test. He was going to need the a mop later. Or maybe a cleaning crew. But this idle thought barely registered as he pulled back and started teasing her pussy with his cockhe...

Fuck that.

*SLAM*

*slorp*

*SLAM*

*slurp*

Splattering noises as cunt juices dripped on the tiles. Slapping noises as his hips made Maximus-shaped indents on her ass. Thuds and more splattering as he slammed his cock into her repeatedly. Moans, screams, howls, begging...copious and obscene mentions of a desire for cum.

This went on for awhile. About half an hour, give or take. Nancy had clearly either previously had or recently gained some stamina, because she was still slamming her hips back to meet his.

As time progressed, his balls filled with more and more cum, until they were resting on the floor and slapping into her thighs as the fucking continued. Neither of them were paying much attention to the details, but if the impossible case of an impartial observer was around, they would have compared them to beach balls. Maybe yoga balls. Not perfect spheres of course, and towards the end of this period audible sloshing could be heard.

Nancy, based on memories of debauchery in her younger days, had not even bothered to count the number of times she came. It was somewhere between one unending orgasm that came in waves, or dozens in a chain. Maybe it was both at the same time. Either way it was unusual for regular humans, and had exceeded any experience she'd ever had before.

Which, frankly, she had expected.

But it was the anticipation of a fantasy fulfilled that had her really excited. "FUCKING FILL ME ALREADY MAXIMUS!!" "GIVE ME YOUR CUM!"

She'd been screaming some variation of this for the last 10 minutes, and applying every trick of vagina muscle application that she had learned over the years.

Maximus was barely holding back what he was sure would be pure insanity, at least from a previous version of his reality. But fuck that version, it was outdated. This was the new reality, bugs fixed and expansion pack installed.

With a final thunderous slam of his hips, he held himself tightly against her ass and roared out his release, a ridiculous torrent of cum blasting out of his dick into Nancy's womb. Neither of them could count the number of blasts or put a value on the volume, but within seconds Nancy was no longer on all fours, but rather resting on her rapidly inflating abdomen.

Maximus instinctually got to his feet as she rose into the air, hands firmly grasping her hips as he held himself deep inside her.

It was probably his fantasy powers or whatever at work, but his massive orgasm came to an end just as she was about to rise higher than he could manage even on his toes.

It was at this point that a police officer came around the corner into the kitchen entrance, weapon out and pointed at the **** scene she knew she'd find.

It was, of course, a female officer, because what else could happen in this new version of his reality? Wait, was his cum affecting fate now? A fairly hot female officer even.

The words she'd practiced in the mirror died on her sexy lips as she took in the scene, and the last thing Maximus saw as he collapsed from lack of water and nutrients was her widening eyes as he slumped to the floor behind Nancy.

"Ah fuck", he thought as he lost consciousness, "I should have remembered to eat something."

Nancy just moaned in delirious pleasure as her hands caressed what she could reach of a fantasy fulfilled.

The officer gaped in confusion and awe as the (really quite awesomely endowed) male fell on his back, his (fucking immense) cock slapping down to point in her direction, the involuntary motion flinging the last vestiges of his orgasm in a perfect arc that landed in her opened mouth.
