She goes for a walk and tests the magic

"I'm surprised you haven't given yourself a dick yet, Mel," Genevieve commented as the human and the genie walked down the street, both of them wearing nothing more than skimpy lingerie.

"You mean why this author hasn't given me a cock yet?" Melody replied. "I assume I'm going to grow one at some point. Maybe two or three, or more. Probably excessively large, too."

"And how do you feel about that?"

Mel shrugged. "Not much I can do about it, is there? I'll grow one, I'll use it, that'll be that. I guess I'll be written to like it, so there's that anyway."

"That didn't really answer my question," Gen pointed out. "Is it something that fits in with your own self-perception of your body?"

"Oh, do you think I'll experience dysphoria or something from suddenly having a dick? God, I hope not. This author is clearly not competent to depict dysphoria properly, so if he has the slightest self-awareness of that fact he'll handwave it away with some bullshit about how it just lets me be more sexually dominant or whatever. As if people with dicks can't be submissive. Just ask any of the guys I've been with. I don't even need a strap to be dominant in bed, never mind some stupidly massive shaft."

"At least with sex genie magic you'll never have to worry about fitting it into whatever holes you want to fuck," Gen pointed out.

"Yeah, because this author doesn't want to grapple with just how sex would actually work when one partner's got forty inches of meat," Mel returned.

"Doesn't seem to be stopping you from handing out overly large ones, though not that large, I suppose," Gen observed, as Mel pointed at a man walking on the other side of the street and his pants suddenly became much tighter around his crotch.

"Just because I'm complaining about the dumb magical contrivances doesn't mean I won't take advantage of them. Bigger dick means more sexual pleasure, more sexual pleasure for people affected by sex genie magic means more sexual energy, more sexual energy means we're that much closer to apotheosis, right?"

"Right, though while it is magic derived from a sex genie via a wish, it's not technically sex genie magic any more, since it's your power that you're using, not mine," Gen said.

"What difference does that make?" Mel asked.

"Well, every time I grant one of your wishes--the ones that are actually sex-related, not the ones where you cheat by getting me off first--I do have an orgasm, though not one you can piggyback another wish onto. And sex genie wish orgasms are pretty powerful, yes, I have to use sexual energy to grant your wishes, but except for the really big ones you do end up positive on sexual energy. I get wanting to have your own magical powers, but you've said you don't want to do orgasm denial with me, so I'm just pointing out that if you were making wishes for all of these changes, I'd be having plenty of them and you'd be charging sexual energy faster."

"Hunh." Mel thought for a moment. "Gen, I wish that every time I use a magical ability I've wished to have, you would have the same reaction as if I'd made a wish to do whatever specific thing I did."

Mel gestured at a woman walking toward them, and her breasts instantly ballooned outward to be as large as her head, her musculature strengthening and her bra vanishing as it was no longer necessary for support. Her nipples made huge dents in her top, but nobody cared because it was the result of sex genie magic.

Gen let out a low moan. "That's much better, Mel. Thanks."

"Can I wish for some sort of HUD where I can see how much sexual energy you've got, or will I need to play with your elbow first?" It wouldn't take much; Mel had wished for Gen to be sexually hypersensitive to her touch, so even the slightest bit of stimulation from Mel's fingers on any part of Gen's body was enough to send waves of climaxes crashing through the genie.

"Nah, that's sexual enough," Gen said, and a progress bar popped into a corner of Mel's eyes. As she figured, it was almost impossible to tell it had been filled at all.

"Funny how infinite power can be achieved through finite means," Mel commented after dismissing the display, then bringing it back and dismissing it again. "Like at some point it just snowballs unstoppably and poof, you're an omnipotent deity."

"As omnipotent as you can be when there's more than one, anyway," Gen corrected. "And Valerie still had to deal with other restrictions, otherwise she wouldn't have needed Emma, and they wouldn't now need you. But it's an amount so incredibly large that nobody would make it there unless she was already gathering incredible amounts of sexual energy, like Valerie, or was pushed there like Emma was, or knew about the target and what would happen and deliberately aimed for it, like you are. But yes, it's like an avalanche going down a hill. At some point you just can't stop it."

Mel nodded. "What about your orgasms? How much are they filling it? It doesn't appear to be too much."

"It's like Claire said, you get as much sexual energy as you would if I was just having orgasms like a normal person," Gen explained. "Nothing from the wish orgasms, and while I do have a lot of climaxes stacked atop each other when you touch me, Mel, each individual one adds so little that even those don't really make a noticeable dent on their own."

"But if I recall correctly," Mel mused, "there's the other part of the orgasm, the one that you can translate into granting a non-sexual wish, and it's way more powerful than the other part. Couldn't we make your tramp stamp capture that?"

Gen cocked her head. "Maybe. It might be too much a circumvention of the rules to pull off even with Valerie and Emma not watching. Oh, by the way, where do you want my lamp to live if I don't have an ass?"

Mel shrugged. "I dunno, your tits? Just find some place to put it."

"And if you decide to order me back into the lamp?" Gen went on.

"Then put it on my body. Make it a womb tattoo, whatever." Mel shook her head to remedy her exasperation at the questions. She had no intention of depriving Gen of a proper body. That would just give her one less cunt to play with. "Well, let's try it. I wish your tattoo could capture all the sexual energy that would otherwise be used for granting a non-sexual wish, if it's not being used for that of course."

Gen focused. "I really have to wonder if there are any rules we can't break at this point, other than the ones that even Valerie and Emma couldn't break. But this does mean one thing... Mistress."

Mel narrowed her eyes at the genie, and the magical being continued. "You're going to have to be careful with how many orgasms you give me now, otherwise you'll finish even faster than Emma did. You could just play with my belly button for thirty seconds and we'd be done."

"OK, then, I wish I could control how much sexual energy from your orgasms actually goes toward filling the lamp, and how many orgasms you have whenever I touch you."

"Granted."

"I assume I should avoid making wishes like Valerie did that would let me harvest sexual energy from the entire universe and every alternate reality linked to it, or whatever," Mel said. "If I don't want to ascend too soon, anyway."

"You probably should," Gen agreed. "It won't be necessary, anyway, as I said. You can reach apotheosis whenever you want already."

Mel nodded. "And otherwise it would take me far longer than I could conceivably hope to live ordinarily." At Gen's nod, Mel said, "Well, just in case, and to avoid freak accidents, I wish for true, absolute immortality." When Gen hesitated, Mel brushed her fingers against the genie's hand, and the wish was granted.

"That won't last if you give up ascension," Gen observed. "We're both going to be ordinary humans after that. Every bit as subject to Valerie and Emma's whims as anyone else, and entirely dependent on their gratitude."

"Remember the plan," Mel said.

"Assuming the plan works," Gen reminded her.

"I imagine they'll be very angry if I try and it doesn't."

"You don't seem too disturbed by the possibility."

"Why should I be? If I don't try, I'm either a God and bound around by those same rules, or I go back to normal because I did something else with it and then I'm as subject to those two as anyone else is, which is no better a state of affairs, if you ask me. Being under someone else's omnipotent thumb is about the most terrible state of being I could imagine. If I try and it doesn't work and they don't know, same place, and if they do know and they're pissed, I've already accepted that they'd do their worst regardless. So I'll just operate under the assumption that it will work. If it doesn't, is my position really any worse than it was yesterday? Only difference is that I know it now."

"I feel like there's probably some sort of flaw in that logic but a genie should never nitpick her Mistress."

"Of course there's probably some sort of flaw. This author is hardly competent enough to spot all the holes in their plots."

The two walked in silence for a while, Mel continuing to hand out various physical enhancements from time to time. Eventually she saw a man with wild dyed hair, but upon reaching out to alter his tongue length so he could eat out his girlfriend better, the knowledge her power gave her revealed to Mel that his natural hair colour was a plain black, and that he had a mess of pubic hair which made it inconvenient for his partner to suck him off.

"Can you get rid of pubic hair while still magically retaining its useful functions?" Mel asked. "I wish for that."

"That's easy enough," Gen said, casually altering human biology. "Not getting rid of the rest of it?"

"I like a hairy chest," Mel explained. "Though I guess getting rid of nipple hair would be nice, too. Anyway, how about some more variety in hair colour and style? Maybe not full anime but let's make hair grow in cooler shapes and more colours. And make it so that it doesn't need to be washed or brushed or whatever." Gen hesitated again, and Mel put a hand on the genie's shoulder to push the wish through.

The change was immediately apparent; there were vibrant reds and purples, deep greens and blues, other colours dotted among everyone Mel could see. She saw various hairstyles that would have been difficult to live with, too, beehives, tails, even a critter, and she could tell that others she could see which ordinarily needed regular maintenance could be kept indefinitely instead.

Melody noticed that her own hair had changed, becoming a pure white, and she altered it so that the underside was instead an ever-shifting rainbow.

"I thought you said you weren't going to go full anime, Mel."

"It's not full anime if there's only one anime hairstyle around."

Gen shook her head. "If you say so."

"I do say so." She suddenly realized where their aimless walk had taken them. "Oh, no."

"What's wrong?" Gen asked.

"The local university is a block away from here," Mel said. "And tomorrow's the first day of classes. We're about to do a cliché university scene."

"Like what, I'm the professor and you're the student who turns her class into an orgy after punishing me or something?"

"Fuck me I hope not. I guess there's nothing for it but to see what this hack has in store for us." Mel and Gen started walking down a path on the campus, Mel once again whispering in the genie's ear.
