Karyn found herself trying very hard not to play with her nipples while thinking about Sarah. Those were separate actions, right? She was just washing up, that's all it was, yeah. People take cold showers when they want to clean themselves after long, weird days like the one she'd just had, that was perfectly normal. Icy cold showers, with water so frigidly painfully biting that you might actually forget that you had just gotten off to none other than Sarah McMillan.
Karyn shivered and plunged herself into the water, hoping against insanity's definition that the chill might actually clear her head this time. She definitely felt the cold; it felt dangerous, the way it ran down her breasts, rinsing the soap off and stiffening her nipples into what might as well have been crystalline rigidity, and then from there down past the wetness of her legs and eventually into the drain. It was all just water. Just the caress of cold shower water. And it was too cold for her to imagine it could possibly have felt at all like the way Sarah had groped her earlier.
Karyn finally sighed and turned off the water. "I guess that kind of helped?" Karyn thought while grabbing a towel. She had decided to take the now-finished shower while her head was still reeling in the aftermath of her orgasm earlier, in some fleeting hope that the, ahem, "stress" she was feeling would just go away so she could get back her clarity of thought. She was shivering, still felt jumpy and a bit weird, but hey, at least with the time to cool off in the literal as well as the figurative sense, she could at least begin to approach the problem rationally, right?
Drying off, Karyn had to bring the towel up to her newly enhanced breasts for the first time since the wish. The moment she did, the words "Just enjoy it" raced through her brain, and suddenly nothing else mattered.
What started off a mere toweling off quickly became experimental squeezes, then some tweaking of her nipples, then it was outright foreplay. Karyn fondled herself lustily, handling her breasts just like Sarah had shown her, mimicking every last caress and squeeze just like Sarah had done it earlier, moaning like a bitch all the while. The world fell away, and somehow she knew a phantom of Sarah was just behind her, dressed in a skimpy swim bikini, reaching around to pleasure her with that frigid cold ring, and if she just made a little wish-...
A wobble of her knees turned into a slip on the slick bathtub floor, and Karyn snapped back to reality just in time to keep herself from crashing to it. Her cheeks were burning red, and she was forced to realize that between the legs she was no longer dry. "So much for thinking rationally," Karyn thought bitterly while toweling off a second time, this time careful about brushing against her... more sensitive bits with the towel.
Eventually, she managed to get a bathrobe on so she could leave the shower at last. She rubbed the mist off the bathroom mirror with the towel, and then looked herself over as if she'd find something completely new and different in her reflection. "What the hell is happening to me?" she wondered. Of course, she knew rationally she wasn't going to see anything abnormal in the mirror (besides, of course, the new boobs and wet blonde hair); the plain fact of it was that Jon could've changed her however he wanted and she'd never notice. Karyn frowned. The thing is, she was noticing, wasn't she? The thing that had happened with Sarah, it was just too weird to be natural! Karyn wasn't into girls! She wasn't! Especially not stupid, sexy, powerful Sarah! There had to be something supernatural going on, she just knew it! There were so many wishes Jon could've made about her already... Jon could be just straight up be making her lewder, or maybe the little perv was scrying on her and Sarah's little makeout session after he wished it would happen, or maybe he made some wish about Sarah she was just getting caught up in, or, or, or...
Back at the Gibson household, Jon had just finished up his homework and his dinner, and had begun the extremely important tasking of mining for diamonds in his personal favorite Minecraft server. The stone was tucked away safely under his bed, and while the idea of making some wishes with it crossed his mind, Jon eventually came to the conclusion that however much magical power he might have at his disposal, it certainly wasn't ever going to make the simple pleasures of video gaming any less fun. So, he logged on and let the hours blur away.
"I just know he's up to something!" Karyn eventually had to say aloud. She was pacing holes in the carpet going round and round in her room, constantly throwing indecisive looks at her phone where it sat charging on her bedside table. The decision currently tearing at her was: "Do I call him?" Normally, she'd never hesitate. Jon was her best friend, after all, and it was painfully obvious to her that him and his stone had to have something to with what just happened. Even if it somehow wasn't involved, certainly they could just find out what was going on and fix with a couple wishes, and that would be that, right? The problem was that she just couldn't trust that Jon wasn't in on it. If whatever was happening to Karyn really was his doing, then if she let slip she was onto him, game over. He'd hang up, grab the stone, wish some things, and Karyn would lose her chance for good. No, no, that wouldn't do. Karyn didn't need Jon anymore. She'd get the stone away from him, bring it to Sarah, and fix things herself. She'd need to be patient; she just had to be careful that Jon didn't find out she was onto him, wait for a good opportunity to snag the stone, make some wishes once snagged, and wham, bob's your uncle. She and Jon hung out a lot; an opportunity should present itself in time.
Satisfied, Karyn finally plopped herself down on the bed and relaxed a bit. Admittedly it wasn't much, but there was something deeply comforting about having a plan, any plan, when confronted with a crisis like this. It meant Karyn could finally stop worrying for the time being and just let her mind wander.
The place her mind wandered to, almost immediately, was onto a vision of Sarah. A delicate, pink, scandalously lacy babydoll nightie did absolutely nothing to hide the skimpy white panties they ostensibly covered, even less so her cleavage, which its deeply plunging neckline made a sexy display of. The phantom was lying in bed with her, taking Karyn's hand in her own, gently guiding it down to the needy regions beneath Karyn's own pajama bottoms...
When she felt her hand touching her pussy and realized what she was doing, Karyn lurched bodily, and the phantom evaporated almost instantly. "Wait... No, no, come back!" a part of her thought at the vision's disappearance, even as another part of her questioned her new apparently lesbian appetites. The former won, apparently, because a few moments later she had her phone in hand, not to call Jon, but to look up "Sarah McMillan" on every social media platform she had access to. Soon enough Karyn was swimming in a deluge of selfies and poses and other shrines to Sarah's vanity, at which her other hand fervently worshiped by offering Karyn's clitoris as a sacrifice to the idolatry. Insofar as she was capable, Karyn had been denying herself the pleasure ever since Sarah's visit earlier that afternoon; so when she finally came, she came hard, and messily. It was a miracle her mom hadn't woken up from all the noise, in fact.
Clarity slowly broke over Karyn with a sense of disappointing revelation. "Who am I kidding? I'm gay for Sarah now. I'm suuuper fucking gay for Sarah now, horny for her just like all those other meathead boys at school," she thought in disgust at the association. "God dammit, Jon... The sooner I steal that stone from you, the better."
Consciously, Karyn knew that she should have every reason to dislike Sarah just as much as she did before. She had nothing but disrespect for the apes of testosterone that constantly and brainlessly seemed to flock to her like lovestruck puppies, and allowed themselves to be blatantly manipulated by someone as fundamentally selfish as she was. She resented just how popular it was possible for her to be, even on the social media sites she had just been browsing, purely by dint of good looks. Naturally, of course, she ended up following and friending her on every one of said sites herself regardless. She even took the liberty of direct messaging her on one of said sites.
Hey, so I've developed some feelings for you ever since, um, what happened between us earlier today. I kinda might've masturbated to it.
Karyn grimaced. She hated that these things were true enough to actually say now, and if this were any context other than private messaging it'd kill her of shame to say it, but of course, she could tell Sarah anything as long as they were in private.
Are you doing anything tomorrow afternoon?
