Mild Guilt, and... Curiosity?

“Fuck!” Jack said, flinching hard. “Don’t scare me like that!”

“Apologies, Jack.” Theta said, looking up at him with the same blank expression she always seemed to be wearing on that cute face of hers. “You were worried about your sister, and I assumed that you would prefer to hear the news from my visible projection.”

“Yeah, well…” Jack said, his heart beating fast and his big dick throbbing hard between his toned legs. “Thanks, I guess.”

She nodded.

He turned back to look at Cindy through the clouds of steam that’d reappeared while he was fucking her, somewhat relieved by Theta’s reassurance. The sight of her made him want to jump her slutty body and gently heaving tits once again, but the brief feeling that he’d done something seriously wrong after pumping her full of cum was still lingering in the back of his mind. Jack’s cock’s near-instant recovery and the quick refilling of his tight scrotum pushed those thoughts away, for the most part, though his guilty conscience was beginning to have second thoughts about just leaving Cindy in her current state.

She was the only one of his family who he didn’t hold any sort of real grudge against, and she didn’t really deserve to be the first person that became his first truely mindless fucktoy, in his opinion.

“I wish the shower was turned off and that the bathroom door was unlocked.” Jack said, then felt himself blink. The sounds of water crashing down all around them ceased instantly, and there was a quiet click from across the room. Jack took a deep breath of steam in his lungs, then released it in a sigh. “Now I wish that we were cleaned up, dried off, and in Cindy’s room.”

He blinked once more, and when his eyes reopened, Jack found that he was no longer sitting on the bathroom’s warm, hard floor. Instead, his bare butt was pressed into a dark gray carpet; his impressive figure shivered on contact with the dry and much colder air air suddenly around him, but he felt fresh, renewed, and while his body was completely dry, it was somehow… moisturized? Jack ran a hand down his near-hairless chest and light set of abs, all the way to the tense, twitching member between his legs, strangely enjoying the sensitive feel of his now soft and healthily glowing skin.

“You hadn’t noticed it when your flesh was wet, but that is simply a byproduct of the elastic anatomy that was previously wished for.” Theta said, sitting against the white wall along with and beside Jack. “Your body, along with the bodies of everyone else on the entire planet, are now virtually indestructible as well. Your physical state, along with the physical state of everyone else on the entire planet, at the time of my magic’s execution has become wholly immune to the effects of aging, disease, fatigue, hunger, dehydration. Not to mention, the entire human race will never again produce bodily waste, either." Theta said, as uncaring as ever.

Jack froze, his eyes wide and his hand firmly wrapped around the upper-half of his cock as he slowly turned his head to face his genie.

“Are you saying that I accidentally made me, as well as everyone on the entire fucking planet, immortal?”

“Virtually, yes.” Theta said. “But it's still possible for a human to die in your current sate. If you were to suffer severe enough or very specifics types of trauma to either your body, or your mind.”

“Lame.” Jack said with a raised hand and index finger, about to correct that little imperfection in his own immortality. “I wish-”

“If you wish to be an indestructible being with a mind that can never die, the resulting changes that need to be made to make that possible will most certainly change you in ways that’ll destroy your current personality and sense of self, Jack.”

“... There’s not a way to get around that?”

“Correct.”

“Fuck.” Jack said, his finger falling limp as his eager grin fell into a disappointed frown. “Lame.”

“Correct.” She nodded. “I am aware of how much you enjoy being you, hence my warning.”

“Yeah, I am pretty awesome.” He said without a hint of sarcasm, then smirked. He let his arm drop, then turned around to face the big-titted sleeping beauty that was peacefully laying on her back and snoring atop her unmade bed. Her long, blonde hair was splayed out beneath and around her head, the guttural sounds escaping her face were loud and crude, and her full, very jiggly, watermelon-sized gozongas were heaving and gently vibrating on top of her with each noisy breath she took. Her thick and protruding nipples were still rock hard, Jack realized as soon as his palm extended and pressed against one of them, the tips of his fingers grabbing ahold of the soft flesh around the areola and giving her huge tit a few playful shakes.

Cindy gasped mid-snore and moaned softly as her brother’s touch, which seemed to be enough to wake her up. Jack wondered just exactly how sensitive her new breasts were if they could wake the heaviest sleeper in the house with such light contact and movement. Her eyes began to flutter open as her limbs slowly became animated and moved to stretch.

“Hnngghhaah…” Cindy sighed and stretched hard, then let out a deep and satisfying yawn afterwards. When her eyes opened, the first thing she saw was the naked and uber-hung Jack standing over her, but the overwhelming amount of sensitive boobage sloshing around on her chest and the roaring flush of kinky memories took the spotlight of her attention almost immediately. “Holy shit!” Cindy cried out as her eyes went as wide as could be, and would’ve bolted upright faster if there wasn’t so much weight above her, but her massive breasts were still sent into a pleasurable jiggle-fit regardless.

“Told you.” Jack said to her, placing his hands on his hips as his erect and foot-long member dangled proudly in front of him. “Magic wishing powers.”

“Dude… That’s so fuckin’ rad.” Cindy softly stated in awe as she looked up into his eyes, the things he’d said earlier now processing through her mind. “So, I can sort of always remember you being able to do whatever you wanted. Was that part of the wish?”

“Uh yeah, sort of.” Jack said, caught off guard by how astute his seemingly-stupid sister’s statement was. “Unless I'm specific, nobody else but me notices any of the things that my wishes change.”

“Oh, okay.” She said, looking away from his face and down towards his big, intimidating cock, and then down towards her own breasts with an expression that had a mix of astonishment and disbelief in it. When Cindy looked back up to meet Jack’s eyes, he saw that she was now smiling. “Can you wish me back to normal for a sec? Like, you can make it so that my boobs stay the way they are if you want, but I want to know how I really feel about all of this, no filter.”

Jack’s heart thumped in his chest at that, unsure of how to answer her request. Part of him wanted to just say no and just fuck her brains out again, but a larger, more morally-nagging part of himself wouldn’t have agreed with that decision. He simply stood there staring at her for a solid half-minute, but Cindy patiently waited for his answer… for about ten of those seconds, anyway.

“Jack… Jack… Jack. Hey, Jack. Hey Jack. Jack. Jack! Jack! JACK!” Still grinning, she wound up screeching her words at him, causing Jack to flinch and snap back to reality. “Is that a ‘yes’, or a ‘go fuck ya’self’?”

“I-… I don’t-… Urgh, fuck it. Give me a second to figure out the wording here...” He sighed, figuring that the worst-case-scenario would just be him wiping her memories by the end of it all if things go south. “Theta, I wish that Cindy’s mind and memories are as they were before I made my first wish, that her breasts were about half as big as their current size, and that she had the ability to see and hear you.”

For some reason, Jack expected his genie to give some kind of warning, or to at least hesitate with such a request, but he felt himself blink instantly after finishing his sentence, and his wish was granted.
