R.A.M.

Your roommate at wizard college is a crazy foxgirl. Fortunately you're a genius. Unfortunately she might be too.

Aria had been one of the most legendary party girls the Royal Academy of Magic had ever seen for four years running. From the very moment she'd started the undergrad life she was the girl at every party ready to mainline the expired potions. She'd done a stand on every keg and been on her knees for every beggar. She was loud, crass, reckless, horny, and incredibly unprofessional having never once done a single bit of 'career building'.

Which was why it had shocked more or less the entire student body when she'd graduated on time, gone on to her masters with significantly reduced partying due to the workload, and finished that as well. It was quite detrimental to her 'campus legend' status, seeing the wild bitch whose snout was the exact size and shape of a beer glass burying that nose in books like '11 Dimensional Knot Theory' and 'Of Holding'.

Surprisingly good for education, though, the school's drop out rate had actually decreased after an entire generation of wizards realized the alternative was being dumber than a foxgirl who butt-chugs expired elixirs. 

In truth, Aria had never seen the contradiction herself. She just went for stuff. When she saw something that seemed like a good idea, that thing would be -done- in five minutes, and she'd roll with it until it entirely stopped working. That was part of why she still had the same roommate, over half a decade with a rat who knew her much better than the rest.

Being dumber than the butt-chug foxgirl was not an appealing prospect , and so you've been working your fingers to the bone ever since just to keep up. They had long since moved out of dorms and into the city, but their sections of the apartment could not look more different. While hers was a barely-lived in space that was used mainly for fucking, feeding, and frolicking (and only occasionally sleeping in), your part was packed with experimental magical reagents, tomes of forbidden knowledge, wands that had been burnt out through overuse.

But what was even worse? Every time you worked your ass off and finally managed to, without any caveats or imperfections, completely ace a class? She'd be right there with you on the winner's podium with an equally perfect score, ready with a headpat and a "clever boy" that left you an uncomfortable mixture of condescended to and sexually frustrated. Just how she was doing so well was beyond you. There was no evidence of any trickery, no sly divinatory magic to give her all the answers... 

But it was down to the final thesis, unless they intended to take another trip around the ivory tower for another degree. Here, finally, you could do your best to get one over on her. The first draft of an enchantment proposal had been denied for being "incredibly, incredibly unethical" and "a future violation of magical law", so you had fallen back on the other subject you shined in: Transmutation, that old gem. You already had some experience with modding your own body; a cock that became a picture of overenthusiastic virility, even if your lithe and androgynous frame was not quite as stud like as it could be.

So a little thing to change that up. A modification of Tenser's Transformation. Instead of granting a whole bunch of benefits at once and taking away the caster's spellcasting, rearranging it into a low intensity but permanent buff to everything. Slowly but surely, you would surpass the fox girl. Perfection would simply take some time. 

You looked over to her at the breakfast table, somehow not hung over despite having been out all night, just fresh out of a 2 hour nap before she made her breakfast. "So, uh... have you decided what you want your final project to be on?" You asked, leaning over the table.

"Like, years ago, yeah. Not exactly a pop quiz," Aria grabbed a frying pan with her hands, a package of bacon with a mage hand spell, and a barbell with her tail as she started rapidly milling around the kitchenette. Even for her it was getting harder to schedule things, and she'd been doing a lot of multitasking lately. 

Fortunately, she didn't have to worry about things like travel time.

"I had to have mentioned it a couple times? Though I might have called it 'Free Teleportation' or 'World in my Pocket Dimensionality' or '11/3' ... I'm still working on the name. You got a spicy one for yours?" Aria asked just as she got her bacon half-cooked and decided to skip the rest, taking a big chomp and adding a second load, gesturing vaguely at you with a sort of slouching language it had taken quite some time to learn meant 'Am I making you anything?' from her.

Aria was, of course, entirely oblivious to her roomie's competitive streak. She had always meant her support fairly genuinely, right down to the most sincere 'Damn, nice cock bro' ever uttered on campus when you had first started enlarging that half. Maybe it was her slender nose and too sharp teeth that always made her look a bit mocking... or maybe it was just the fact that she'd been tall and perky -before- she started working out, and now was visibly the only Archmage student to have gotten in better shape over the course of the year.

You glared at her for a moment, but then nodded at her offer. She was as good at making breakfast as she was at anything else, and well... that generally meant a pretty solid breakfast that you'd be stupid to deny. 

"...eleven three?" You mused, an eyebrow raised at the somewhat... undescriptive name. "Okay, now that one I don't get. I've just been calling mine the Super Package, because... well. Superhuman attributes. The superb package is a different spell, which I suspect the grading panel will not find terribly interesting or amusing.”

Still, she did note that he seemed a little worn down. Frustrated, perhaps, as he worked away at a series of very specific components at the table.

 "Basically, rethreading the 11 spatial dimensions that exist into the three we usually use to make them traversible," Aria answered idly, leaving an awkward silence filled only with the sound of cooking bacon. It eventually finished and she piled it onto a butty with a tomato to toss at her roomie.

Ah, yes. The pair had ended up diverging slightly in terms of the curriculum; higher dimensions were more the purview of Conjuration and Evocation other realms and high energy states, respectively, whereas you were very much a man in search of the Philosopher's Stone with the Transmutation/Enchantment focus. Therefore, when it came to comment on those dimensions. "Ah, yes. All eleven spatial dimensions that I can definitely name and identify."

"And, Super Package sounds like it fits! Certainly couldn't hurt to include the b-end. I mean, I know I wouldn't consider superhuman attributes 'complete' if it left out the -fun- attributes," Aria pulled up her shirt to tease you into dishing or just make him feel better. It was her experience that -everybody- liked looking at her boobs, even gay rats. But if anything the more surprising eyeful was the heavily enchanted navel piercing she'd apparently stuck in herself.

You pretended to flinch as she flashed you, but it was obvious that you still took proper eyeful through your fingers. "New piercing?" you asked, focusing on an Unseen Servant spell to do the more focused work of dishing up breakfast that a mage hand might be too sluggish to attend to.

Aria checked you components over your shoulder, racking her own brain for connections and how they'd work out just in case she had any advice, but so far her only contributions were a sandwich and full frontal

The components looked mostly solid, actually. It seemed like a reasonable utilization of every Enhance Ability spell at once, forced through a permanency spell which somewhat limited its output, she noted, and then drip fed to the caster. Knowing your habits, she reasoned that you'd probably get there, eventually.

"Oh yeah, you know how it goes," Aria flexed her stomach, abs flexing enough to show up on her lean stomach as she wiggled the navel around, "whenever you start something new, you want a magic item or two to help out. And, well, I thought wondrous items were too old school and had to learn piercing based magic... so now the 'training' item gets shoved right in the soft bits."

It hadn't been her wisest choice, and honestly your project looked -way- easier than what she'd planned. It was pretty fun that they'd both end up in similar areas, though. "Can't think of too much to add to yours, everything looks good! I guess you could make the growth regulator concatenating instead of merely interlocked, it'd make the permanency circuit easier to sustain, buuuut it would also mean you couldn't -not- improve any of the linked attributes."

You gave the piercing a brief squint. Shoving the training item right in the navel?  You supposed it was one way to deal with it that wasn't wasteful... There were more than a few wondrous items amongst his collection of things gathering dust, mainly because he needed an edge on occasion to try to keep up with Aria. It wasn't an inferiority thing; you were talented, and supposed that made it worse when she approached things so effortlessly.

Like making a casual but very apt proposal for his project. He buried his nose into his chest a little as he glowered at the spell component he was working with, then sighed and started rewiring it. "God. You know, I actually thought about that immediately, but "you can't turn it off" sounded like bad practice. Really, when you think about it, it's not a downside at all..."

"Hells yeah, man! That's what I'm saying," Aria clapped encouragingly. "I mean include an emergency shutoff. I did. But my options are 'keep adding more weight SLIGHTLY slower than I adapt to it' and 'emergency shutdown so I don't implode' and I don't see any problems with that."

Honestly, it was kinda a hot idea. Roomies with a growing hypergenius rat who -can't- stop getting more stamina, more flexibility. Aria's own experience with flesh shaping just about covered healing and hygiene, but... "If you wanna experiment with anything, feel free to toss stuff my way, I think we're both gonna floor 'em," it wouldn't -hurt- to learn a few interesting ones.

"Oh, yeah. I bet teleportation has all kinds of horrible implosion-based failures that you have to guard against," You nodded... but then actually processed what she was saying. Adding more weight? Was she talking about the barbells? Did teleportation require weightlifting capacity?" You took a moment to think about it, but the unwiring and rewiring of his spell component was a lot quicker than successfully finishing that thought.

"Okay, let's see..." Normally, people who could cast 9th-level spell slots weren't this young... but then, neither of the people in the apartment was exactly normal. Pouring magic through your form, your body briefly glowed a transcendent, blinding blue-white...

You just went for it, and for a moment, Aria had stars in her eyes, astounded by the feat of magic. You couldn't help but love it as well, not just the rush of energy as your body began changing, but getting one over on your rival. It was an amazing feeling. And it would only feel better.

Over the next week, you started to feel the benefits trickling in. Every morning felt just a bit lighter, just a bit hungrier. Every night needed just a tiny bit less sleep and woke up feeling more refreshed. Aria was actually incredibly helpful, greeting them both with something like two chimaera steaks for breakfast every morning, and your constant bodily improvement never found itself lacking an audience or fuel.

Things were downright perfect, until one morning Aria greeted him completely naked, and he got a good look at her. She was... muscular. Athletic. Toned like one of the monks at the nearest monastery the school hired meatshields from. More to the point, she was visibly much bigger than she'd been a week ago, and apparently growing faster than Nick.

"Hey, wanna help me pierce my nipples? I think I need to get the next stage going and I kiiiiinda don't wanna do genital piercing just yet." Her question was also concerning on -multiple- levels.

You frowned. There really wasn’t a coherent  response until you had chewed on it for a while. "Uh... interesting. Did you... cast an enlarge spell, or something?" you said just to fill time. It was alarming, particularly because "Hey want to pierce my nipples" wasn't really the kind of question that one would ask if they had the intention of shrinking back down again.

"But I can... probably help, yes..." you replied, though with a definite overtone, undertone, and regular tone of pure suspicion. You limbered up a little, the new shirt bought the other day already starting to look a size too small on you body as it pressed against abs and pecs that actually existed, in a form beyond the hypothetical or merely functional for the first time.

"Hmmmmm... that's actually an interesting philosophical question..." Aria paused, erect nipples in her roommate 's face, to get nerd sniped and consider the philosophy. "I -want- to say no. Transmutation and conjuration have overlap in places, and admittedly bodily enlargement -does- use some spatial manipulation principles, but not only is nothing I've cast so far targeted at my body, it's mostly focused on the opposite. Compression, shrinking, pocket dimension stuff..."

Aria blinked, finally remembering where she was, "Oh! Wait, that was a compliment for boobs. Because boobs. Sorry party brain was last night but this morning is wizard brain. Nah, my chest isn't any bigger yet, I wanted to get them pierced -first-. If you want sex we can do that afterwards," the foxgirl levitated over a set of adamantine needles and hooks, two nipple bars with large runed studs at either end, and an apparent refusal to elaborate on her own offer.

"No, no... look." You conjured a mage hand, levitating it to about the height you had presumed she would be when first thing in the morning. The height you were familiar with. "This is how big you were," he grumbled, then put the hand up to Aria's hairline. "...and this is how big you are. You did something, though it sounds like perhaps you did it in a moment of party-related inebriation." You rolled your eyes, taking a look at the materials. Adamantine? This seemed entirely overkill for the problem at hand.

Of course, the seeming and the reality were two different beasts. More magic had to be poured into the spell, still continuously improving you, effectively running the engine until it was red hot just to get enough strength to pierce flesh. "What the hell?" You seethed through clenched teeth, trying to get a perfect piercing. Anyone had to admit they were rather nice nipples, after all, and it would be rude to leave a mark.

"Oh."

"Huh."

Aria... hadn't done something. Not intentionally at any rate. How had she not noticed herself getting -taller-?

Well... she knew that, admittedly, she rarely paid much attention to her surroundings. After she'd first learned spells for sensing foes and traps she spent a lot of time not looking where she was going. She'd probably just assumed that everything seeming smaller was a side effect of her vastly increased strength, which -was- entirely intentional.

It was a very concerning development. If this was a side effect of part 1 of her process, she'd need to make adjustments before continuing. Which, unfortunately, was not an option with red-hot needles actively pressed against her chest. It was splitting her several ways, she had to focus on not moving, but now there were -issues- to deal with. She didn't want to get speared, but continuing might be trouble...

...If she had realized that you was struggling and her skin was resisting adamant, one of those problems would have vanished. Of course, the other would have been revealed to be much worse.

You were, generally, a "work smarter, not harder" kind of person. Not really a raw muscle kind of guy. That said, sometimes the most effective way to solve a problem was to go barrelling straight through it. Aria felt a sharp nip in the nips as the needle finally went through. He drew it back, the magical alloy glowing with destructive evocation energies, and dropped it in a ceramic dish. As the glow faded, she noticed the tip was completely blunted. You picked up the next and started again on the opposite number.

"They certainly chose the pricy materials when they made you," he complained, refining his technique to try to get the next piercing done swiftly and elegantly. "But it does give me some ideas. Maybe sword-resistant fur would be handy to have... or perhaps absorbing Disintegrate spells... hmm. Options, options."

“How would you absorb disintegrate? Wouldn't 'not dying' cover it? I feel like being hyper-integrated would also be dangerous, molecularly..." Aria hadn't prepared a trainer ring, and could already feel herself starting to heal, so she quickly fastened her next magic tool anyway. She had to admit, it did look pretty fetching. When she'd been damage proofing her own fluffy fur, she'd been pleased with how tiny her nipples were for practical reasons, but getting to 'fluff' them up a bit with bars pressing up on either side did make her look more inviting.

Even if your continued struggle showed her to be more the opposite. She couldn't even argue. She -had- spent her life's savings on various components and enhancements.

"Never say no to a glut of pure magical energy, I always say... unless it's in killing form, which the absorption would be intended to mitigate. And I'm sure being hyper-integrated wouldn't be dangerous for long, just until you get the instability out of your system..." You held the needle tight as he prepared the entry site, then focused a Catapult spell, winding as much of your metamagical prowess into it as possible.

The resulting explosion of force left their fur blasted back, the pair of them looking windswept as Aria's boob jostled with the energy. There was a neat puncture, just as intended... less intended was the disappearance of the adamantine needle, having been launched into the countryside beyond somewhere through a tiny pinprick in the walls. "...oops. Well, there you have it, anyway. What are those piercings for? They smell like magic..."

"Right! Should probably focus on that. Pre-prep was increasing my mass quite substantially, this is part two of the series..." There was a click and a sigh of relief as Aria slid the other piercing in and briefly glowed with the magic of a heal spell, her chest recovering instantly and taking on an obscenely perky, gravity defying state...

Along with the rest of her as gravity lost its grip on her and she rose into the air a bit. Testingly she did a couple loop de loops, leg going over her head and then back to the ground again as she rotated herself slowly... then -vanished-, before coming back seconds later with the very bent needle you had just launched into space, which she idly tossed back.

"It's just four basic spells, one for telekinesis, one for escaping prisons, one for teleportation, and one for slowing time, but the innovative part is -combining- them with my Body of Holding to increase the effect floor in proportion with my mass, that way as long as the original effect applies..."

You blinked. That may have been a mistake. Blinking. In the split second you closed your eyes; they were both at the beach, Aria floating, stretching out, and looking wistfully up at the sun. 

With ice cream.

And you.

"I call it 'True Freedom of Movement!'"

You blinked again - which, this time around, wasn't a mistake. There was a brief moment of quiet as you stared at the floating foxgirl with a perturbed hesitancy. You paused just long enough for a few shirt buttons to snap off, pinging against the wall of washboard abs that was hovering just above you as your chest was inadvertently bared. At least you wasn't the only one showing off his chest...

It was a concerning mastery of dimensional travel. In fact, there were a lot of concerning implications in play. For a moment, you felt the shadow of something greater washing over you, the thalassophobic heart-swallowing urge making your tail curl nervously behind him. "That's, um, pretty impressive, yeah," you said, somewhat lamely, a blank look on your face as your ears were pinned back.

"Er, when you say it increases in proportion to your mass... that must be why you grew, right? Put on a bit of extra muscle weight to boost the potency, right?" The phrase 'Body of Holding' was also ringing alarm bells. Hiding a true mass, perhaps... you rubbed your hands awkwardly together as you craned your head up at her, casually enjoying ice-cream on the beach as though she hadn't just worked an incredible piece of magic.

"Well that's the trick, isn't it. I've been gaining -fucktons- of muscle, but it's not really supposed to be showing. It's getting taller with the compression on full blast that has me a little worried." Aria fingered her navel a bit, rubbing the bauble this way and that as she tried to feel out its enchantments. They -should- be working, and yet it was unmistakably surrounded by abs. Abs that had gotten longer and deeper and thicker when they shouldn't have been able to change even by packing on hundreds of pounds of mass.

The problem was that she couldn't actually check to see what the problem was. Her project only had an emergency shutdown, and she got the feeling that going 'fully natural' with her body suffering.... unexpected... results might be a bad idea. Even some of her extra spells seemed like a bad idea to just shut down. She wasn't so punk she skipped her ears entirely when looking for places to load up, she'd just done them years ago with rings to help her skip out on food and sleep, but she was starting to see a downside to the fact that even totalling 100% of what had entered her body wouldn't -necessarily- equal her weight.

So she really only had one option, and it was by far the thing she was worst at.

She asked for help.

"You're basically the world's greatest flesh-shaper, right?" She asked you without a -hint- of buttering him up, it was an easy enough acknowledgement as your former fat-assed nerd body was currently pushing 'king of the beach' proportions. "Can you teach me some? I may need to learn in a hurry... or, if nothing else, I might need somebody to do a deep dive on my body, figure some things out."

 "Uh, well! I... hope that's the case," You murmured, nervously rubbing behind your ears. She had laid quite a problem before you that didn't seem to have a good or clear answer. Silently, you wondered if it meant your more cautious approach to things was indeed the superior one, but just as quietly you suspected that she had just wandered into consequences that were just as good as the main effect. If not better. You stalked around her floating form in the sand, checking it out with sight, sound, scent, dipping into his magical senses to try to puzzle out what was going on.

"Okay, I can let you look at my grimoires. Unlike SOME wizards, I actually keep mine well-notated so that people know what the fuck they're actually looking at. Honestly," you added, spiralling off into a tangent. "If someone is reading through your spellbooks, they had better damn well be someone you invited to do so, because if someone gets THAT close to your stuff, you've already failed on the security angle."

You waved a hand, getting back on track. "Er, anyway. Yes, I can help. BUT," you added, straightening yourself up and taking a serious air. "I get ice cream too, AND you have to clean up your potion bottles and ale kegs without me asking."

"Ha, sure!" Aria privately thought 'sucker' to herself as she converted one of her most contaminated potion bottles into a fine glass powder which blew away and teleported the stack of kegs she'd been saving back to the brewery, getting it out of the way early. 

It actually helped provide You the full rundown of what was going on.

That being that Aria was big.

Aria was very, very big. 

The mundane senses telling you that Aria was about seven feet tall with her nose buried in a chocolate cone were dirty liars, because Aria was vastly bigger than that. 

It came in the form of a tingle, a sense of pressure, the feeling of intimidation everyone got when approaching a dragon in their human disguise, that whisker pressing sensation that said, "We are standing here because I told physics no. If reality had its way, you would be inside me."

At a gesture, Aria hovered away.

And away.

And flew all the way to an ice cream stand where the beach started to rejoin the city, negotiating with a furiously blushing and deeply concerned looking bear salesman to get you a cone.

Without getting far enough away for the sense that Aria was still -here- to fade.

 It was that feeling of being submerged in the ocean again, that truth you had picked up on before pressing its way into reality. That mere shadow of something bigger actually coming into view properly, and a hull of unimaginable size swallowing the horizon.

You felt your own magic roiling through your body, slowly but surely making him better in every way. Smarter, stronger, more sizable. All in the aim of catching up to her, maybe finally showing the world that you could do better on your best day.

All of that felt very far away and very small all of a sudden. Sheer size wasn’t magical power, of course, but all the power bound up in all the little tricks and tweaks she had compiled together… it was unfathomable.

So when she “returned”, if one could really relate to her physical location in such terms any more, the colour had completely blanched out of your furless ears. You reached out slowly to accept an ice cream cone, but she saw your eyes roll back as you collapsed back into the sand instead, tongue lolling as his blood pressure spiked into the ground.

The button keeping his pants together exploded for good measure, but hey, that just meant she had two ice cream cones, now.

"Oh shit, are you okay?" Aria looked around in panic, not exactly expecting you to just... pass out. She cradled you telekinetically, keeping your head from just pounding into the sand, but you seemed... oddly limp. 

Except for one part. The largest cock she had ever seen was throbbing violently at the sight of her, and she... briefly rewound the train of thought that was going through horrible magic accidents to remember basic medical information about blood flow.

"Wait... did you make your cock so huge it's exsanguinating your brain?!" It was the hardest thing she'd done in weeks - skipping past laughter and incredulity to just throw some healing magic at you. Blood replenishment was one of the easiest spells there were, and while making somebody heal further while already at 'max' was actually quite hard, it had been one of the first things she trained for her own project, so you rapidly felt consciousness return...

...Before it immediately pumped into his cock, again, the monstrous member throbbing bigger the longer he had to look at his nurse.

Aria looked at it, a dangerous menace in the form of a person-sized pink cock, and raised an eyebrow at you , just a bit. "You know... I could have sworn you were gay..." she mumbled, running her claws up the cum vein, watching it shudder. -Magically-, she knew exactly zero dick related spells. -Sexually-, however, she was an expert. "So if this turns you straight... well! No better way to do it."

"W-wha? No, I was... contemplating my own mortality, thank you very much..." you replied with a breathless murmur. It was... half true. Adding that girthy monster had been pretty effortless, true, and it was the quality of life features that had been tricky. Especially with a dick like yours, that looked like a "shower" despite very much being a "grower", with only a limited supply of blood in a body. Still, 99.99% of the time, the body modifications worked perfectly. 

You had not considered the possibility of a cosmically-sized foxgirl, especially not the one who had casually blown through a magical university like it was a fun hobby. You weren't sure, exactly, what you were feeling. What you were supposed to feel. It was all very dangerous, very new territory... but your cock had mostly decided what to feel, it seemed like.

That feeling was only amplified when she surged more healing magic into it, your dick surging with height until it towered over your body, newly-thickened legs bowing around colossal nuts as they gurgled ominously, the magic ring that housed the Superb Package spell, legally distinct from the Super Package spell that was cast only a week or so ago naturally, growing alongside your cock as it throbbed angrily and hungrily. You did, of course, know many dick related spells. Maybe you could slow her down by giving her something to think about in the form of a needy organ?

That would probably have to wait, though. Her touch along his shaft was certainly... dangerous.

Aria watched the little man significantly outgrow the man around it and hurried up her timeframe a bit. Shoving malfunctioning magic inside her body was one of her least favorite additives... but she was enough of a size queen that the -form- it took more than made up for that.

It would even be a fun way to put her new movement through its paces. She levitated up to the top of your towering shaft, fingers idly teasing under your foreskin. You weren't as wet as she'd expected, but, then, your body might not physically have the resources to produce that much pre, so Aria quickly teleported over a bottle of lube from home, squeezing it dry and making a small gel-cyclone to get you as ready as possible. 

She wrapped both her cheeks around your head, carefully teasing it with the press of her softest parts. She'd been careful enough, even with her rapid increase in athleticism, she still had enough cushion on top of her enormous glutes to make it a pillowy paradise. You could -feel- her asshole, the barrier at the end of it all, and was reminded of how hard her body resisted even the hardest substance on earth.

You probably shouldn't have worried about -her- needing to resist. Aria pressed -down-, and you saw stars, more cock than he'd even -had- enveloped in the tightest, smoothest, strongest hole imaginable. 

She was bigger on the inside. 

Aria slowly lowered herself down, pawpads teasing the lubed up cock as she made a show of pulling herself down inch by inch using her flexible legs, but that's all it was, a show. Aria was still flying, lowering herself with magic vectors, pressing inches at a time down with a blush and a smile. 

The magic wasn't to force her down, it was to keep her -up-. The fox's body didn't stretch, every foot you pushed into was already -there-. She was being polite. Delicate. Protective. 

Keeping the monstrously massive milking muscles from dragging you in all the way to the hilt - and beyond. Keeping the titan in the form of a college girl from slamming you in and wearing you like a sticker. Keeping it so that the pump and roil of a sphincter that could shatter dragonbone only touched and teased and titillated the first -third- of your cock.

That conflict between interior and exterior size roiled in your brain. Not so much that your newly-superior intellect couldn't keep up, but enough that it made your brain fry with the implications of such incomprehensible power. That it was already suffering under the weight of hormones and sensation merely meant you were locked into a pleasurable buzz, instead of completely insensate. That slow roll down the length with a mix of perfect softness and irresistible strength kept your shaft at perfect firmness, oozing with every moment, fat cum vein rippling with every pulse of precum.

You thought you’d probably be very thirsty afterwards, and resolved to put together a spell that would draw moisture from the air so you didn't need to drink. And figured that Aria's appetites might not get any less vigorous with time, especially if she had resolved to learn fleshcrafting from your example.

As she inched down, while you did not physically feel the weight of her mind-boggling size, you felt the presence of it. Laid flat out as nuts continued to pound out fluid, throb after throb, you merely let your chest rise and fall as you watched her work, dancing around his pole like she owned it.

"Ffffuck, god..." you muttered, exhaling audibly as she tweaked her hips and sent a blast of sensation rolling down your length to the sensitive nerves along your spine. "How? How did you..." You had more questions than answers, but not the wherewithal to voice them. How did she get so much power? How did she do it all so casually? How did she work those hips so well? Your claws dug into the sand, grabbing hold of anything you could to keep yourself grounded as she lowered herself effortlessly against him.

"Get so good at this?" Aria teased, finishing your sentence,somewhat incorrectly at that, as her paws reached your balls and started kneading them and her butt descended the rest of the way. She actually got her feet under herself, tilting your cock towards your chest even buried inside her, never quite rough enough to hurt... but forcefully enough it was getting hard to think of the cock as 'yours'.

"The tantric sex magic class that they cancelled because it turned out to be bunk? It wasn't that good for magic, but for learning the sex part..." Aria started to bounce, "they taught advanced kegels," Your vision went spotty, "positions like the recurrent lotus," then fully white, "and even a few tricks like how to use Presti to add a sensitising effect when you clean up." Then, vision was the sense you could worry about the least.

Oh, what sights there were to see when one did not need their eyes to see them. Your magic senses were burning hot, perceiving a well but not the boundless depth of it all. The interplay between the softness and the hardness of her curves and muscles, the paralyzing inability to run his hands against her abs and return what he was given...

It was all a bit much, every piece of you working at her whim as she bounced along the shaft. It should have stretched her, should have left her bloated and quivering, but... it did not. It was like it wasn't doing anything beyond tormenting you as she glided along it, moving at the speed of her desires... you tried to respond, but only managed a breathy exhalation as you twitched under her, her grip so tight that you feared you would only cum when she let him. When she made you.

It was the largest dick on campus, which meant Aria planned to savor it. To caress every bit of her insides with her new toy. To go -deeper- even though you was running out of cock and she wasn't running out of butt. 

She'd -planned- to, but as she felt you start to give and prepared to adjust her approach -just enough- to edge you for as long as she pleased, she remembered two things through her own pleasure haze. The first was that this was supposed to be a quickie.

The second was that you might actually explode if she tried to make you hold all that cum in.

Instead she threw open the gates, relaxing her butt, psychically spreading wide, -encouraging- the cum vein to stretch and unload, giving you a moment to breathe.

Immediately she was rewarded with cum.

A cup, as you sighed and twitched.

A pint, as the magically amplified balls started to clench properly, finally free to unload.

A quart, one moment doubling the greed of the last.

A gallon, surging even beyond that as the main load finally hit the tip, as -everything- finally came out.

And even beyond that…

Rats were, of course, built with heavy nuts as standard. And you were not currently operating under a standard configuration, however, heavy had become ridiculous, balls intended for regular breeding had instead become a whole fertility clinic, and the pressure and weight...

Well, they were a little fun for the fox, perhaps, but for the rat? Every nerve in your body was screaming at you to stop doing what you were doing, while your pleasure centres nestled deep in your brain said "actually, please don't". Either way, you were pinned by your own escalating sensation, hands curled into claws like a dying bug as you moaned and grimaced through a truly incredible cumshot.

You weren't sure when it would end. If it could end. Pint, quart, gallon, barrel, hogshead, it was all the same, running together with pulse after pulse that roared through you like a thunderstorm. The only saving grace was that spell working on you, trickle-feeding more stamina so that you could carry on without passing out - though you weren't entirely sure if that was a mercy or not at this precise moment.

You weren’t entirely sure how long it took for your balls to finally empty, but you did recognise that you was panting and sweating as your vision finally resolved into something more than grainy whiteness.

Aria waited until you finally started to soften, blood retreating and refueling your brain, then she finally hopped off and let you rest. She turned around, holding the massive -even more so now - cock in her hand, and gave it one brief lick, testing the last drop of cum to see it was still thick and sweet. Then she gently lowered it over your thighs, legs spread wide by the absolutely massive balls still pressing them apart even drained and loose in the sack.

You were built like a barbarian warlord now. Twitching pecs and massive shoulders, raw -beef- on every inch of your frame. You self improvement spells were still pumping - possibly more than ever with your stamina actually pushed - but you had enough blood to not die which meant Aria could do one important thing. 

"Do you need some help with your project?" she asked, "I can make you something so that we only do... -that-... intentionally in the future."

Magic research wasn't -quite- as fun as savoring the afterglow, but she had no idea how long it'd take a cock like that to recover.

You took a moment or two to actually recover some kind of sensibility, chest still rising and falling with rapid breaths though with more muscle packed into it than ever. You were overwhelmed in every sense of the word, with cosmic terror lingering at the back of your mind, sizzling nerves at the forefront, and squished in between a cock and a hard place was the reason you were in this position to begin with.

Were you more compos mentis, perhaps you would have felt a touch of shame at the asking. He ought to have been standing on his own two feet, using his self-improvement to try to surpass Aria. Right now, though, your head was sufficiently empty. And was putting on no airs when you replied, making no posturing gestures.

"Hhhh... yeah, probably..." you wheezed, rubbing some of the floaters out of his eyes. You watched your cock continue to twitch like a hungry snake, thankful that it was utterly drained so that it wouldn't drool all over his body. "Can you- can you take me home? I need to lie down..."

It probably wasn't a good sign for you and their future work together.
