Magical Trade
A commission for Eco (who requested to not be linked), in which a witch trying to use magic to enhance her figure makes a welcome mistake and "borrows" her partners assets.
Glowing wisps of magic floated through the air, charged with power. Candles burned in a small square, a dim light showing the pattern written on the floor. In the center of it a woman kneeled, alternating between gently applying a paintbrush to her nude form and checking her written documentation to ensure the symbols were appropriate.
Ruby's magical studies were varied; her current project was the study of runes, applied to objects to induce various changes. In this case, the “object" was to be herself, although as her brush gently applied her specialty paints to herself, she noticed nothing felt too special. It was uncomfortable; the flames provided little warmth in her basement, but it was the only part of her house suitable for her ritual, and the cool paint didn't help. At least it stuck firmly in place, not that this stopped her from worrying about smearing any by accident.
By the time she'd finished, the candles were already a quarter melted down; she made one last check that the runes around her chest and hips were correct, her hand mirror a valuable aide. Confident in her work at last, she finalized the ritual with an incantation; she herself didn't understand the words yet, but recognized a few common words in her work. She felt a tingling sensation, the paint sinking into her with a sting, but smiled, knowing her spell would change her soon.
As she stood up, she took stock of her weight, how her bare chest moved in the air, how her legs swayed with each step. Soon, she would improve all of them, although as she turned on the electric light and extinguished the candles, she grew slightly confused. She'd expected her spell of growth to work quickly; looking over the printed copies of musty old tomes confirmed the effect of these runes was quick.
She sighed; either she'd messed them up without noticing, or have never used the right ones to begin with. Before she could return to the books, however, she heard a voice calling to her from above, happy and cherry in sharp contrast to her own mood.
“Did the spell work, hun?"
Taylor, her girlfriend, peeked down into the room, a smile on her face. Her casual shirt and skirt highlighted her assets; a larger chest, wider hips. Ruby sighed, slipping her clothes on heedless of her partner's stares.
“No, just gave me tattoos. I need to figure this out now…"
“Aww, honey…"
Ruby's outfit for the evening was a simple dark dress, covering her arms and legs fully. She threw on a stereotypical witch's hat to match; a cute flair the couple enjoyed. Her disappointment in her mistake was eased by the warm embrace of her girlfriend; she was always a comfort, even when also a source of envy. Ruby could feel a tightness in her chest as they cuddled, before Taylor stepped back to lead her out.
“Come on, I finished dinner! It's a lovely vegetarian rice dish, I'm sure you'll love it."
The two couldn't help but smile as they enjoyed their meal; Taylor's cooking was great, and the two always found comfort with each other. As they both scooped up pieces of rice, though, they fidgeted in their seats, finding themselves feeling just a little uncomfortable in their clothes.
“Can you pass the sauce?" Taylor asked; as Ruby shuffled it over, they could feel a small jolt in their hands, although both quickly wrote it off. Neither caught on to Ruby's chest growing, just a little, her chest only a few centimeters bigger than before; likewise, Taylor's smaller hips were written off as her having accidentally stretched her clothes out over time.
“So, I guess that's another spell off the list?" Taylor asked between bites, leaning forward a little.
“Yeah, even with the real spells it's hard to know which ones work for who. At least your cooking is great as always~"
“Oh, thank you! I changed the recipe a little…"
Ruby giggled, taking the moment to lean over and kiss her partner on the cheek. After she pulled back, she noticed she'd managed to catch some rice on her dress, quickly wiping it away; her chest, even with the relatively small growth, had changed enough to catch in her food for the first time in years. It was Taylor's turn to giggle at the sight, enjoying the cute moment, unaware that Ruby's swelling bust was the cause.
As Ruby finished off her meal, Taylor stood up to collect her dishes. In the brief moments where they touched, passing the plate off, she felt another tingling; starting to think something was off, Ruby concentrated, realizing she'd definitely grown, her hips wider, her chest a cup size larger. The spell must have been having some effect, but she was still confused by it, although as Taylor took her hand and pulled her to their living room, she tried to set her worries aside, even as she felt the tingling once more.
The two held each other close, Ruby gently nuzzling into her partner's cheek. She couldn't help but blush, however, as she realized that her chest was pressing even tighter against her dress than normal; Taylor likewise seemed to feel strange, her shirt hanging looser than it should, her bra seemingly too large for her. It was at this moment that Ruby realized just what it was that her spell had done; she was making herself larger, but needed a source for the new mass, and evidently her girlfriend's touch let her take the needed material from her.
She paused for a moment, hips wiggling in place as she thought about it. It wasn't too late to undo the change, see if she could reverse this… but it felt oddly good, not just that she was matching- and soon to surpass- her partner in size, but that she was taking it, that she was adding her partner's mass to her own. By the time Taylor noticed anything odd, Ruby was already smiling, but with a clearly mischievous look that the other woman had learned to recognize as trouble.
“Um, Ruby, have you grown…?" she asked with a bit of uncertainty, her eyes drawing down towards the straining fabric of her dress, watching it grow thinner slowly.
“So, good news, the spell worked after all! The 'bad' news, well…" she giggled, pressing a hand into Taylor's chest and squeezing, watching her blush even as the sensation was somehow lessened compared to normal. Taylor would only let out a soft gasp, before giving a firm but gentle push to her partner, breaking the contact and stopping any further changes. With the connection broken, it afforded Ruby a chance to stop herself, realizing just how much she'd already stolen.
“Oh, oh that's… a lot more than I realized…"
“Yeah… although, um, it kinda feels good…"
Taylor took the moment to bend forward, giving Ruby a quick kiss on the cheek. Now that both knew what was happening, they couldn't help but enjoy the tingling, Ruby taking note of small flashes of runs matching her own just under her partner's collar.
“Does it hurt?" she asked, leaning forward and holding Taylors' hand.
“Not at all… it's weird, but it's not bad." she replied, enjoying watching as her breasts shrunk, sliding her shirt down to watch; they were easily only half their original size, and it was oddly comforting to her. Memories of why she'd taken on a gender-neutral name for herself resurfaced, and she giggled a little at the sight before looking back to her partner.
“Maybe we should take this to the bedroom?"
Ruby nodded in agreement. The two were careful not to touch each other even as they both filed together into their bedroom, sitting opposite each other on the soft, violet covers. Taylor's skirt had fallen off, and she simply discarded her ill-fitting clothes; conversely, Ruby struggled to undo her dress, ripping it while she tried to pull it away. The two looked to each other, the runes circling Ruby's body glowing faintly in the light.
With both of their forms bare, it was now clear to see a set of runes across Taylor's skin, matching Ruby's in position but with opposite symbols to hers in key locations. The sight was quite odd, but it at least assuaged any concerns she had over how controlled the spell was; it had firmly latched onto Taylor.
“How does it feel? It stung a little for me…" Ruby asked, making one last check-in.
“It feels… nice. Like, the rune itself is a weird tingle, not good or bad, but my body… I kinda envied smaller folk, you know? Thinner, more androgynous…" she shyly replied, looking away but speaking clearly.
“Ooh, is that why you changed your name to be gender-neutral?"
“Yeah… I, um, wasn't sure when to tell you, but this makes for a convenient time, yeah? Might even try out new pronouns…"
Ruby giggled, leaning down towards her partner with a predatory grin.
“Well then, let's take this a bit further, alright? Turn around for me."
Taylor nodded, turning to face away from her, a blush spreading across their face as Ruby took hold of each breast in a hand. She held them firmly, yet was careful to not scratch them too much with her nails, trimmed to stick out just a small bit. As she pulled Taylor close, they could feel their chest compacted slowly, faster under her direct touch, yet still slow enough to bask in the effect.
Ruby's own breasts soon pressed into their back; her nipples were stiff from the open air and her own arousal, and she rubbed them in with every little movement. She leaned around to whisper into Taylor's ear, her voice alluring and calming at once.
“Now, I'll be taking all of those lovely curves, hmm? They may have been nice on you, but we both would be much happier if I took them for myself~ just use our safeword if you need to stop, if you think I've taken enough. Alright?"
Taylor was sweating, feeling a mix of their own flushed warmth and her partner's own heat as they nodded in agreement. It was starting to get hard for them to speak, but they'd already managed to work out that they could still call out a safeword in this state. Their own hands bent down, squeezing into Ruby's hips and thighs as they wrapped around their waist, letting them feel firsthand how they were swelling, slowly, growing centimeters wider over time.
Ruby smiled; this night, this spell, it was all far better than expected. She'd wanted to enhance her own body, to make herself fit her self-image; now she was getting that, but also doing the same to her partner, and in a kinky way that gave her an unexpected thrill. She made a mental note that she should try this again in the future, perhaps with a third party.
She grinned as she pulled her hands closer to Taylor's chest, loving the feeling of their breasts shrinking away; from her past experience she could guess they were in the range of B-cups for their body size, a far cry from their original size. Her own chest was growing to match; she was guessing it wasn't quite an even exchange, but she was hardly gonna complain about their swelling up, finding each now larger than Taylors original size by a slim margin.
Ruby let one of her hands fall, running slowly down Taylors' body, stopping just above their crotch as she gently teased their crotch. She couldn't help but notice her hips were now larger, while Taylor's had slimmed further; surprisingly, they weren't shrinking anymore, as if the magic had a built in safe limit for how much it would take.
Pulling her partner in closer, Ruby gently kissed their ear, watching them squirm in her grip. She swore a small portion of her thighs had grown to match her hips, but brushed it aside, her finger brushing closer to Taylors' clit.
“Unfortunately, I don't have any toys around right now, but my fingers can work more than one kind of magic~" she teased, gently pressing a finger down against their crotch. Her other hand managed to push closer to their ribs, breasts reducing to a midway between the smallest sizes; both of them could tell that within minutes Taylor would only have a bare minimum of fat left on her chest, their tits reduced to pecs.
She smiled as Taylor quivered, pulling just a bit tighter on their chest, enjoying the change in sensitivity as they finally leveled off, her own chest continuing to swell for several moments after. Her nipples pressed into their back as she finally started to directly stimulate their crotch, fingers gently pushing inside them. Taylor panted, their chest only barely any more sensitive than the rest of them and yet still feeling quite nice as their partner massaged it, small hints of breasts remaining. They could feel themselves dripping onto the bed, the mix of euphoria from their body and the teasing of their partner too much, but they were able to restrain themselves for the moment, turning slightly in her grip.
“Ah… can you… top me, please?" they asked, speaking between breaths as they looked into her eyes, almost seeing a glow in them as her magic flared up.
“Of course, dear~" she replied, happily letting go, sliding away to allow Taylor both the chance to catch their breath properly and lie down. After a minute, the witch climbed onto them, her impressive chest now easily dwarfing theirs, hips covering up her partner's as she took gentle hold of their wrist.
“Ready?"
Taylor nodded, and Ruby dove in, pressing her lips against theirs in a deep kiss. One hand held theirs up; the other made its way down to tease their slit once more, with Taylor joining in, their work a bit sloppier than Ruby's but no less pleasurable once they found their groove. Each ran their fingers gently along the others folds, sometimes poking along the clit, sometimes just running around the edge, sometimes sticking deep inside.
Soon enough, Taylor came, gasping for breath a little. Ruby took this as a sign to ease up, going easy on them, her own breathing heavy as she joined her partner, pleasure surging through her as their juices mingled on the bed. She smiled as she eased in next to them to cuddle; the sex itself, as good as it was, was secondary to their changes as far as either was concerned.
As the two drifted into sleep, too tired from the magic and sex to speak properly, they felt a small tingling, familiar yet odd; neither paid it much heed in their tired state, simply enjoying the others company.
The next morning, the two woke up around the same time, still feeling exhausted after last night. Ruby realized she didn't feel any tingling anymore, and as she looked down at their bodies, she saw why, crying a little as she realized something she'd overlooked. Her partner was alarmed for a moment, looking over themselves to figure it out.
“What's wrong, hun? Oh, I… my body…"
Taylor forced a small smile, tilting Ruby's head back up. Overnight, the spell had worn itself off; specifically, the painted-on runes had lost their effectiveness, as between the sex and cuddling and sleep, they'd smeared onto the fabric of the sheets and blankets.
“You found a spell that works, and the only limitation was that it needs the runes to stay on your skin, yeah? What if the runes were IN your skin instead?"
Ruby blinked a little on hearing the suggestion, thinking it over. She hadn't considered that, but she did know some witches who'd gotten other magical body-mods, and gears started turning in her head.
A few days later, after checking to confirm the spell would work with ink within the skin, Taylor stood waiting outside a tattoo parlor. Between the spell being one that worked better in private, and their own inability to stomach looking at needles, they'd been unable to attend their partners sessions in person. The extensive nature of the tattoos, combined with the extreme precision needed for the magic to work, meant several consecutive days worth of waiting; luckily magical healing meant the stinging was brief, and magic suppressors kept the unfinished runes from having any effect.
Finally, the door opened, and Ruby stepped out; her low-cut top showed the finished tattoos along her upper chest, a perfect match for her previous painting. She happily hugged her partner, and they kissed her cheek back; already, they could feel a tingling, Taylors chest deflating ever so slightly as they stepped back.
“So, the spell works now?" they asked, looking over their partner.
“Yep! Of course, once I take your figure again we'll need to get new clothes, and the artist has sent ahead to a doctor to hook us up with more suppressors so I don't start stealing everyones tits…"
Taylor giggled, leaning in to kiss her again, enjoying the feeling of their hips shrinking away slightly.
“Say, do you… happen to know something to help with fear?"
“Fear? Yeah, I've used a few spells to help get rid of fear before, why do… oh, cute, you wanna make sure your side is permanent, too, don't you~?"
Taylor giggled and blushed, the two happily embracing once more. Another patron carefully stepped around them, and a tightening in Ruby's bra helped alert them to their inconvenient spot.
“Let's take this back home for now, alright?"
Another week later, and the couple found themselves exploring the aisles of a magic-friendly store, exchanging their ill-fitting old outfits for new ones that would match their style. Taylor giggled as they set a pointed and wide brimmed hat onto Ruby's head, only to be quickly met with her setting a joke stuffed animal hat onto their head in turn.
Nearby, a timid young woman looked on at the two, taking note of the runes of their matching tattoos. She couldn't see them fully, but it was enough to get her curious. Once Ruby noticed her, she stepped up to the young woman, a small smile on her face as she greeted the fellow shopper, eyes implusively looking toward her impressive bust for a brief moment, the ohter woman quickly taking notice.
“Is there something I can help you with, dear? We're not employees here, but we can still show you around!"
“Ooh, actually, I was curious about your, um, rune tattoos…"
Taylor let out a hearty laugh as they approached, a pile of clothes on one arm, the other keeping it from falling off.
“Oh, these? Long story short, my wife here-"
“We're not married yet, hun."
“-my girlfriend and I both wanted each other's figures, so she found a spell that let her take my curves away!"
“In fairness, it was an accident, it was just meant to make my tits bigger!"
The couple giggle to each other, enjoying sharing the story. The other woman blushed, stepping back a little, her face making it clear she was debating her next question.
“So, um, do you think you could maybe, um, share that with me? I have a 'friend' who was thinking of getting her breasts reduced, and might as well help someone else, right?"
Taylor nodded in understanding, while Ruby blushed, honoured at the prospect.
“Hey, if 'your friend' wants, we can do it right here and now; these runes don't just work on my partner, and I can unlock the magic for a bit, right? Assuming Taylor here doesn't mind, at least."
They shook their head, giving the others a bit of room.
“Oh, not at all! My wife getting even more tits for me to play with? I'll happily let that happen!"
The young woman blushed, taking Ruby's hand in her own.
“O-oh! Well, in that case, I'm Lilac!"
Already, she was a little more confident, looking upward more, a small smile forming on her face. Ruby and Taylor smiled back, happy to let someone else change their body.
“In that case, how about we head to the changing rooms? I'll give us some privacy, and plus there's the names~"
“You know, hun, you seem to be enjoying this a lot. Maybe we should get into this business ourselves, helping folk with this?"
“Oh, that's a good idea! It'll be a great use of my… talents~ But let's save that for after my first new client, hmm?"
As Ruby led Lilac away, the two talking over exactly how much of the latter's bust the former would take, Taylor settled onto a bench to look over nearby magical jobs. By a stroke of luck, there was already an experimental new clinic, specializing in magical transformations and body-mods; a perfect place for the couple's new arrangement. They saved the webpage, giving out a satisfied breath as they waited for Ruby to return, ready to start a new chapter of their lives together.
