[Seriously, this is completely ridiculous. I warned you.]

"Carol! Get out here! The surprise came!"

Carol's voice echoed from the opposite end of the same apartment. "I'm getting ready for work!"

The short, petite redhead stomped her foot, the folds of her robe rippling gently. "God damnit, hurry up! You'll be late, even if I wasn't giving you your birthday present!"

Carol ran out from the bathroom, hands in the air. "I'm here, I'm here! Geez, where's the fire, Flamey?"

'Flamey' grumbled, waving off her best friend and roommate's complaints. "Look, it's your birthday present and I have to give it to you before you go to work!"

Carol stood before her friend, placing her hands on her hips. Their differences couldn't be more extreme from each other. Carol was tall, reaching 6'3", while Flamey reached 4'3" - and that took a lot of stretching on her part. That had the unfortunate side effect of Flamey being entirely hidden underneath Carol's significant bosom, it's size resembling a close comparison to two large bowling balls held against gravity. It didn't help Flamey that she could be hidden completely under Carol's chest due to the lack of any breast tissue herself, being flat as a washboard.

Flamey, given her nickname for the short cropped and spiky red hair she sported, took a step back from her friend. Her face was covered in various paints and generally looked messy, albeit in a cute playful manner. Carol's face was pristinely washed and made up, every detail perfect. It was perfectly framed by her straight blonde hair that cascaded down her back to her hips. She looked like a flawless doll, while Flamey looked like a worn toy.

It fit their professions. Flamey, working from home as an artist could look the part; she even swore it helped pull in the customers. Carol worked at the hospital, so her modest and subdued makeup conveyed the appropriate level of professionalism.

"Look," Flamey began, making eye contact with her friend. "You're always complaining about your height, your breasts, all that. It's too much, people don't take you seriously, yadda yadda yadda. Right?"

It stung, having all her insecurities thrown at her like that, but Carol couldn't deny it. She stood out in a crowd, and that was putting it mildly. Her own anxiety amplified the issue beyond what it actually was, but she would still get stared at all day and it didn't help with the image of professionalism she tried to present.

Carol nodded, cautiously. "What, did you find a way to get rid of all that?"

Flamey grinned wide, grabbing the yet-unnoticed paper bag off the counter. She reached in, grabbing and shoving something at Carol. "Tah dah! Happy birthday!"

The box was small and flat - roughly the size of a movie case, Carol noticed. The white packaging was nondescript and when she ripped it open two small plastic triangles fell out of the box.

Flamey scrambled to pick one up, grabbing the wider of the two triangles that had a large glossy "R" on it. Carol mimicked the action, grabbing the thin piece with a "G".

"So… you got me a triangle… wow…" Carol drily remarked. "Look, it's not that I don't appreciate it, but I need to get to work."

"Look, I know, it sounds crazy so let's just try it out. Do as I say. What's something about your body you wish you had less of? Think about it. Anything. Now, say 'I give to you' and whatever it is."

Carol stared at her friend, seriously wondering how crazy she was. Weighing her options in her head, she decided it couldn't hurt to just give it a go then hurry to work after. "Fine, I'll try it. Don't know what you think will happen. I give to you my breasts."

The plastic polygon in Carol's hand glowed and warmed up suddenly. She tried to let go of it, but found it stuck to her hand. As soon as she turned to Flamey to protest, it stopped and fell from her open fingers. Her jaw dropped simultaneously with the piece.

Flamey's triangle had been glowing too, though she hadn't panicked and was still holding it calmly. Carol suddenly realized why Flamey was wearing only a robe, as any clothes wouldn't have survived her transformation from flat chested up to the sudden F cup breasts Carol knew too well. She noticed, as Flamey stopped struggling in vain to close the sides of her robe - electing to keep it open, instead - that the nipples were still pierced.

Almost as though Carol's breasts were now Flamey's.

Flamey giggled, adjusting to the new weight and sensations. She pointed at her roommate's chest. "See?" Carol looked down and gasped, instantly shooting her hands up to her empty bra. She bit her lip, then turning away from Flamey unbuttoned her work shirt. The bra fell away from her body readily, and she examined her now completely flat, almost boyish chest. She grinned, turning back to her friend as she rebuttoned up her shirt.

"Holy crap! How? Where?"

Flamey waved her off. "Don't worry about it." She noticed Carol going for the G triangle again. "Just, make your next donation more specific. Don't want to give all of something every time."

Carol wasn't fully listening, and nodded errantly. "So like, this can do height?" At Flamey's nod she continued. "I give to you half my height!"

Before Flamey could shout at Carol to stop, the swap had already occured. Carol tumbled to the floor, the suddenly loss in height left her heavily disoriented. She staggered to her feet, finding her clothes awkwardly large on her suddenly 3'2" frame. With her reduced size and her flat chest, she almost looked childlike, though her made-up face helped dismiss that.

Flamey grumbled from across the room. "Think before you use the damn swappers," she groaned. Carol surveyed the expanse of her friend. She looked long and gangly - only height had been transferred, not mass or size - and she shot from her normal 4'3" up to a staggering 7'5". Her head had nearly hit the ceiling, and she ended up collapsing into a weak pile of limbs.

"Oh, shit! I'm sorry Flamey! Uhh, I want to take my height back! I take from you my height!" Despite Carol's repeated and frantic pleadings the piece she held in her hand didn't glow again.

A long arm reached over and grabbed the G piece, dropping the R piece on Carol's lap. "G for Give, R for Receive. They only work one way." Flamey sigh, rubbing her forehead. "I give to you a foot and a half of my height."

The girls looked at each other, and slowly stood up. Flamey's robe was long since destroyed, and she shrugged off the exposed tatters. With a bit of adjusting and straightening up, Carol was able to get herself presentable again. She couldn't stop beaming as she looked her friend in the eye, for once being the same height.

"I could wear heels now! I can be the little spoon with my boyfriend! I'll be able to find pants in any style I want!"

Carol was practically bouncing on her heels, and Flamey just rolled her eyes. She swapped the swapper pieces so that Carol once again had the Giving triangle, and Flamey the Receiving.

"Look, take that with you to work. If you think of something else, go for it. That's your birthday present, a day of getting rid of stuff you don't like. Just… be more specific, ok?"

Carol nodded, hugging her suddenly busty friend tightly. "Thank you, thank you, thank you!" Carol glanced at the clock. "Shit, I have to go! I'll make any last minute changes there. Thanks, bye, love ya!"

The door slammed shut, and Flamey was left in the empty living room in a sudden quiet. She didn't fuss too much over it, and collapsed on the couch to watch Netflix, still entirely nude.

At least an episode or two went by when she felt a warm burning against her side. She pulled out her piece of the swapper, and watched it fade back down to it's full colorless white. She shook her head, chuckling that her friend was using it again. A small part of Flamey worried Carol wouldn't mess with it more.

As she shook her head, she noticed how her normally short hair was now falling around her face. She stroked it back over her shoulder, and noted that it didn't reach her rear. At least Carol was being more specific, she thought to herself.

Another warm glow from the swapper. Flamey furrowed her brow, not expecting it so soon.

And then another one.

Flamey paused her show, and stood up to look herself over. She didn't notice any changes; everything still looked the same. Swiping her phone off the coffee table, she shot a quick text to Carol.

Flamey > Hey, the Swapper just went off twice??

Nothing, no response. Carol often was busy at work, so Flamey just had to let it go. She turned her show back on, only mildly paying attention. She was curious about the changes to her body, and being in the nude like this only offered her the opportunity to explore herself with her fingertips, only mildly touching her new curves.

The Swapper warmed up again, and again, and yet again as more changes wracked over Flamey's body in rapid succession. She lost count of the changes when they finally stopped, and was shocked at her body.

She was tall again, and had to be at least six and a half feet tall. Fortunately she wasn't gangly this time and had a healthy weight on her limbs. Unfortunately, she had a more than healthy weight on her chest which had seemingly nearly doubled in size. Her hair had reached down to just above her feet. Luckily, Flamey had some hair ties within reach of the couch, and tied her hair back on itself multiple times to make a thick ponytail of sorts.

She grabbed her phone, mildly irritated by the changes happening. Fortunately, Carol had already replied to her first text.

Carol > Really cute patient, started getting "distracted", figured I'd try giving you my horniness and was surprised it worked?

Carol > Then I kinda was like… don't need my pussy if I don't get horny. So… yeah.

Attached was a picture of Carol's crotch; she must have run to the bathroom to examine it and the strangeness of it was enough to send Flamey a shot of a solitary tiny hole for her urethra.

Flamey started punching out a text about the most recent changes, surprised when Carol answered almost immediately.

Flamey > So… want to explain how you had more hair and height and tits to give me? Thought you were all done with those.

Carol > Ya remember Nancy? My best friend?

Carol > I couldn't keep lying to her about how I was so different, showed her my birthday present from you…

Carol > So she wanted to use it to. You know she has a lot of the same problems I do here with our appearance. She did everything I did, hair, height, breasts, sexuality, vagina.

Carol > We'll come home right after work and change back. I promise. Thank you thank you thank you!

Flamey sighed, watching the stream of messages end. She was probably back to work, and nothing she could say could change them back now.

It explained the changes that Flamey couldn't figure out too. She reached down, touching a finger between her legs. Only one pussy to speak of there. She slipped her finger in, noticing it many times more lubricated than usual, as well as deeper and more sensitive. Even with only her brief exploration, by the time she pulled her finger out she was panting from how turned on she was.

Idly, she put her finger in her mouth, cleaning the digit. She paused - she was never ok with this before - until she realized that Nancy was bisexual, so now Flamey was too. The thought of her identity being changed made her hesitate for a second, but she let it go, it's not like it would harm anything, and besides, it would be temporary.

It became a struggle to not keep touching herself. It turns out, with three times her normal arousal and sexuality as well as new and overly sensitive breasts and crotch it was an ever present temptation to avoid. Her show offered only a vague distraction, a sense of something to do so she wouldn't do herself.

Carol > Shit shit shit. Manager pulled me + Nancy into office about the changes. Didn't seem pleased.

Carol > She is making us all come to a group meeting. If what I think is about to happen is happening, I'm so sorry! I owe you! Big time!

Flamey have noticed the texts. To be honest, she was ready to just masturbate and go to bed, so it wasn't much concern of hers, especially as she got closer and closer to giving in and playing with herself.

Carol > Oh shit, she told everyone what I told her.

Carol > She's forcing me to let everyone use it. Saying we'll use the Swapper the other way tomorrow after work.

Carol > Fuck, I'm sorry Flamey. I really fucking owe you. I'll text you the changes so we can reverse it tomorrow.

Carol > Gina's giving you two cup sizes, a foot of hair, her, and I quote, "basketballs for asscheeks" and her sexuality and vagina.

Flamey groaned as she could the Swapper burning again. She could toss it across the room, but who knows if Carol would get in trouble if it stopped working and considering she was the one paying for the apartment… better to play along, Flamey figured. These changes weren't too bad, compared to Carol and her friend being giantesses with plenty to donate away. Though, her butt now felt like a couple of pillows had been welded to it, which was strange to sit and wiggle on.

> Carol: Rachel is next. She's giving a foot of height, a hundred pounds of weight, the same sex stuff as usual, and… I guess it worked?

> Carol: She gave "5 years of her age" to you and looks a bit older, like she's the age all of us are now. I guess you're only 22 now? Congrats!

In all honesty, Flamey couldn't really feel the age difference, but she imagined that she did. Her mind was swirling with terrible and naughty thoughts, unable to stay fully focused on what was going on. Fortunately, a hundred pounds across seven and a half feet of height vanished easily, making her frame look more balanced.

> Carol: Uh oh, sorry in advance for this one.

> Carol: The last girl on tonight, Sally. She's giving you the same amount of butt that Gina did, all of her G cup breasts, the sex stuff, "a foot of height and the muscle and fat that goes with it", all of her ass length green hair, and all her piercings and tattoos.

> Carol: Wow. She looks… entirely different. I bet you do too. I'm kinda scared to come home and see you tonight, please don't be too mad.

Flamey collapsed back on the couch instead of reading her phone. The changes to her size and stature were hardly noticed by her, instead she was in awe of the massive globes that quivered uncontrollably. She had run out of fruits and melons to call them long ago, and could only think to describe them as each the size of a small bean bag chair. She let out a long moan as her fingers stroked her body, her mind addled with sex. She kept running over various studs and bars of metal that were punched through her skin, it seemed Sally was nearly addicted to piercings as Flamey was now covered in them as well.

The same went for tattoos. Anywhere that a work uniform wouldn't cover, tattoos had sprung up across Flamey's body. But instead of the gothic skulls and spiders and such Flamey had seen Sally with before, it was all versions of Flamey's art that were permanently stamped into her skin. Which made sense, sort of, since the Swapper took something and made it yours. Otherwise she'd have half a dozen pairs of tits right now.

Carol > She's making us all do a couple changes together, hang on.

Carol > Well, none of us have fingernails or toenails anymore, which is weird. Apparently if we all touch the Swapper and one person says something it happens to all of us.

Flamey squealed with surprise. Apparently the fingernail lengths added together, creating long and well maintained talons covered in a mix of a thousand marbled paint colors. She ran them over her body, the nearly extra foot of reach they offered allowed her to explore the more distant curves of her breasts and even find a faint hint of her nipples.

> Carol: Shit, I forgot Greg and Mike are working tonight. They're coming in too.

> Carol: Good news, they're keeping it simple. Bad news… they're guys.

> Carol: I'm sorry!

> Carol: They're both touching it, and the manager is making them give up their genitals and sexuality, and their height and muscles. Shit, she made them give up three feet each!

Flamey's body shot out. Her body filled the living room, fortunately with enough muscles to hold herself up. At least her chest didn't look ridiculous on her now. She hesitantly looked down at her newest member. There it was, twitching and already dripping. She worried for a second about those very drips potentially getting herself pregnant, but realized that it was her own seed. The chances of that happening were minimal, if biology was to be remembered.

The guys must have been well endowed, because on her massive body her cock didn't look all that small. She wrapped her hand around it and groaned, nearly orgasming solely from that touch.

> Carol: I think that's it! I'm sorry! Anything you want for the rest of time! It's yours!

> Carol: A lot of people are going to come by tonight and get… their bodies back. That's weird to type. We'll see you soon. Just… six hours.

Flamey faintly heard her phone buzzing. It wasn't important. What was important was fucking herself silly. She managed to crawl down the hallway to her bedroom and shut the door, pulling out her 'toy box'. It took a hearty amount filling her holes before she felt sufficiently prepared to grind against any flat surface she could, given her size. At some point, she knocked into the clit piercing she received from Sally, now industrial sized to fit her body. It buzzed to life, vibrating with the motor of a jackhammer. Her eyes rolled back, and that began the first orgasm of many that night.

Flamey would get Carol back, certainly, but that wouldn't stop her from enjoying this in the meantime.
