Apparently, actually showing a change as it happened would have been too interesting, because nothing was different until Jon woke up, early the next morning. He woke up with a case of morning wood, which wasn't unusual; but, said boner was poking into someone, which was VERY unusual.
Whoever she was, she was laying nearly on top of Jon, curled up against him like a teddy bear in his arms, and definitely nude. They were both nude, under the sheets, actually. He could feel all of her before so much as opening his eyes: her soft, smooth skin against his, her toned, firm muscle, her wide hipbones, and of course the big, supple boobs squishing wonderfully against his own chest. She smelled slightly spicy, and like sex; and in the predawn stillness there was only her gentle breathing to hear.
Jon's eyes fluttered open before he was fully awake. It took him a long moment to process that it was Karyn. Only, it wasn't Karyn; she had apparently been changed by the Stone. Her boobs had been pretty big before thanks to earlier wish, but now they were properly huge; and her ass was now also "pretty big" too. Apart from that, she was slimmer, more physically fit; all blemishes had disappeared, and her face had become... well, cuter, in a lot of subtle ways, and her hair had the movie star quality of only being slightly messed up by sleeping.
To put it another way, Karyn was now very very very Conventionally Attractive. She could have been a supermodel or a pornstar with that body, or maybe both.
Jon stirred. He had changed too, and he wanted to find a mirror and see exactly how, but Karyn had him imprisoned as surely as an adorable sleeping lapdog. She stirred too, and her first action was to cling to Jon even more tightly.
"You can't get up yet, Jon-boy," she purred dreamily, without even opening her own eyes. "Not with thaaaaat~!" Her hips wriggled against his morning wood. Of course it stood even more stiffly despite himself.
"Karyn...?"
"Shhhh..." She opened her eyes, still half-asleep, and pushed herself up to straddle over him. "Let me take care of it for you~" she cooed, and lowered her bare pussy onto his dick.
So, Jon and Karyn ended up fucking for a solid chunk of the early morning. Jon kinda just let it happen, on some level being too tired to try fully comprehending what was going on, and on another level too ecstatic to really care. He caught, somewhere in there, that apparently they were a couple in this new reality, evidently with a VERY active sex life, and their sleeping arrangement had been the end result of another one of their dates.
"I'm on the pill, it's fine," Karyn reassured while she was putting on a reverse striptease for her boyfriend getting dressed. "You don't have to ask me every time we do this, silly! You know I'm your good girl~," she added, putting an extra wiggle in her hips as she said it, even while trying to stuff her thick ass into her skinny jeans.
"Of course," Jon replied, but still couldn't resist a thoughtful look toward their pet rock. Karyn noticed, but Jon covered himself with "And I guess we have a Plan C now, anyway."
"Exactly!" Karyn gave a little bounce as she turned, pants now on but still topless apart from her struggling, lacy bra. "So quit worrying and fuck me more! You KNOW how horny you make me!" Karyn had her hands on her hips, leaning forward confrontationally, but that little smile on the corners of her lips betrayed that she was just playing and wanted an excuse to show off her fat cleavage.
"If you insist!" Jon tried to say it like he was just returning the joke, but honestly it didn't feel funny to him. He put on pants of his own and let the subject drop, choosing instead that look in the mirror he'd wanted.
He too was a little more muscular, a lot more fit, and devoid of blemishes. He was taller, his shoulders were broader, and all his excess body fat had disappeared seemingly overnight. He was shapely now, but not cut; his belly looked like it was maybe a week of exercise away from sporting a six pack. And sex with Karyn had pretty conclusively shown him that his dick was bigger.
Conventionally Attractive. Very Conventionally Attractive.
"You're just mad that a STUD like this is off-limits!" Karyn teased, hanging off of Jon like he was a stripper pole.
"Fuck off," spat back Jon's little sister and only sibling. That she was an irritable goth girl hadn't changed, but the rest of her...
"I'd be pretty frustrated too, if I had all of THIS for a brother!" Karyn's hand found Jon's chest.
"First of all, gross, and second of all, I said, FUCK OFF!" Zoe yelled.
"Zoe!" Linda Gibson, single mother, enters stage left. "Inside voice, dear!"
Oh, my. Her too. were Jon's simple, unsurprised-but-still-disappointed thoughts upon seeing his mother for the first time that morning. She'd gone from your plain, average, forty-something Mom with too much on her plate to a voluptuous, curvy, conventionally-attractive MILF that just radiated cozy maternal safety from her body. He'd figured something like that would've happened to her after seeing Zoe (now a pale, pretty, bosomy thing whose soft body looked much more suited to the Twilight Saga than to sunlight), but he still had to wonder just how deep the Conventionally Attractive Curse would go.
"C'mon, be honest," Karyn insisted. "Lemme ask you honestly, if Jon wasn't related to you, and you saw him as a dateable stranger... Would you?"
"I..." Zoe seemed to be making the mistake of actually considering the question for a moment, because her gaze shifted to Jon for just a moment and she blushed, blushed much too hard to save face.
Linda did too, actually. "W-what are you girls even fighting about?" she asked, trying very hard not to meet Jon's gaze while so flustered.
Zoe found her fight again. "I was just trying to get this whore to quiet down on her 'dates' with Jon, and she accuses me of incest! We can all hear your moans all over this house, you two, it keeps me us up at night!"
"Yeah, probably because you touch yourself to it," Karyn snarked back.
"NO! Fuck you, Karyn, I'm not into weird shit like that!" "ZOE! Language, young lady!" "Sure you aren't." "I'm NOT!"
The room erupted into chaotic catfighting, and Jon tuned it out after the first sentence or two. "Not into weird shit", huh? Somewhere in Jon's head the pieces were starting to click together. There's probably a timeline out there where the stone makes all my Perverted Fantasies a reality, he reflected. All the "weird shit", all the bizarre degenerate fetishes I should never admit turn me on in public. This timeline... is not that timeline. Detached, he observed the pretty girls bickering over all the sex Jon was having as if from a distance. This is hot, but this ain't it. I'm into much crazier things than this. But those would be too interesting.
He nodded appreciatively. Working theory: This is all just bland, generic, vanilla pornography. Uninteresting, Lowest Common Denominator smut, not the truly Interesting Fetish material it could have been.
As the catfight escalated, he had a thought. Sarah McMillan's gonna be a doozy.
