“Alright, last check before we start, since once we get into the introduction I don’t want to have to start again…” Brianna said, looking around the repurposed dinner table.

“Why’re you looking at me?” Lydia asked, “I only had to go to the bathroom at the start that one time…”

“Character sheets?” Brianna asked, rolling her eyes. A chorus of affirmations responded. “Dice? Rules reference sheets? Anyone need to use the bathroom?” Yes, yes, no. “Alright, looks like we’re good to go then…”

It was game night, and Brianna White had finally managed to wrangle enough people together for a tabletop rpg. Between herself, her twin sister/clone Brooke (it was a long story; villains, brainwashing, new distinct personalities, etc), her girlfriend Lydia, and her friend/rival Samantha were all superheroines, and that didn’t leave much room in the schedule for spending a night playing games.

But for once, they’d all managed to clear their schedules, and nobody had forgotten any critical materials or that they’d had some appointment they’d forgotten about. They’d gotten their sheets together, she’d laid out the scenario, and they were good to start. Brianna launched into her opening narration, setting the stage of a city in turmoil and the machinations of a strange dragon-cult hiding in the sewers beneath. The party introduced themselves as they met in an inn, with Brooke’s Tiefling bard playing her instrument for the tavern, Samantha’s Elven Rogue lurking in a shadowed booth, and the Half-Elf Paladin played by Lydia watching the potential criminal with suspicion.

Brianna settled in. The opening was going well, so far, and the characters were establishing themselves mostly through player-directed actions. But freeform rp wouldn’t go on forever… she rolled some dice for an NPC, the inciting incident ready to kick off. “Out of the corner of your eyes, movement. You didn’t notice them at first, but they’d been there the entire time. A cloaked figure, moving towards you… they’re close, now, and as you turn to ask what they want, they-”

“Tell you about a much more fun way to play this?”

Brianna felt she should have been surprised by the voice coming from right beside her head. But when it came to Morgan, nothing surprised her anymore. She turned to the side, and saw the woman standing over her shoulder with a mischievous grin.

Morgan - powerful mage and shapeshifter that she was - could look like anything, but over time Brianna had gained something of a knack for identifying her. If she wasn’t taking the form of a specific person, her cup size wasn’t so much a letter grade as “the biggest in the room”. She tended to be sexy, with deep curves and a gorgeous face to match. The other, perhaps more important factor, was body language and tone; Morgan was probably the most self confident person Brianna knew. It’d be arrogance if she didn’t actually have the general competence to back it up.

“...Does it have to be now?” Brianna asked with an exasperated sigh. “It’s been months since we were able to get the group together, and I’d like to participate as something besides decoration or your clothes.”

Morgan raised a hand to her mouth in feigned shock. “Oh, what kind of monster do you take me for? I wouldn’t ruin your night with your friends like that!” she said, “In fact, I want to make it more fun.”

“Look, whatever you’re planning with me, can we just do it tomorrow night?” Brianna asked. Of course, she knew that it was a bit of a pointless gesture at this juncture. When Morgan thought of something fun to do, she was going to do it.

“Nope! You’re playing today, and it’s no fun if I just do it randomly.” Morgan waved off the complaint, before cracking her knuckles. “Now then, this is a role-playing game, right? So how about I help you immerse yourselves, hm?”

With no further warning, Brianna felt a strong pull down towards the table, and stumbled over. For the brief second she had, she saw the others also pulling towards the table, stretching out like cartoon characters as they were sucked downwards - in particular, towards the miniatures representing their characters.

The last thing she saw before the world went black was a new miniature forming on the table, one that looked a lot like her.

-----

It was in the blink of an eye. She closed her eyes looking at the kitchen table, and opened them staring at sapphire blue skies. Looking around, she was certainly no longer inside her home.

Brianna was standing on the side of a dirt road, in a hilly plain. The ruts in the road created by passing carts were the only sign of civilization; otherwise, it was green as far as the eye could see.

She wasn’t alone, either - as she’d expected, she saw Brooke, Lydia, and Samantha each looking around in much the same way as she was. “Well… guess Morgan’s got her own plans, huh?” Lydia said.

“She always does, doesn’t she?” Brianna sighed. Nobody had been transformed yet, but with Morgan’s usual modus operandi, Brianna was certain that state of affairs wouldn’t last for long. As if on cue, just as she thought that, she noticed the others begin to change, all at once.

If you asked Lydia, transformations were interesting. She of course hated the bad ones, the sorts cast by real villains. She didn’t look for them actively. But Morgan’s changes were different - always meant to be temporary, since if she just changed someone into a pair of panties and left them like that, that was the end of the fun. And she did make them enjoyable. So when she felt a tingling feeling, she almost welcomed it. Morgan was going to have her fun, so they might as well enjoy it too.

The first change was her height. She was a bit above average usually, but she gained several additional centimeters until she was head and shoulders taller than the rest of the group. Her tank top and shorts gave a good view of the continuing transformation, as her already athletic figure gained even more muscle mass and definition to fit her new height. Lydia smiled to herself, striking the sorts of body-builder poses she’d seen in magazines to show off, and making sure Brianna saw.

She had grown bigger on the whole, but that wasn’t the end of the transformation. Next, her barely-existent bust swelled to several times its original size and her bottom ballooned to match. At the same time, her modest curves deepend to give her an hourglass look. While Lydia wasn’t one to be angry about her lack of bust size - as far as she and Brianna were concerned it didn’t matter. But that didn’t mean she wasn’t going to feel them up when her apples turned into melons, which she promptly did. They were big enough to stand out even on her newly more muscular frame, and she’d be lying if she said she didn’t like the feel of them.

Her black, shoulder length hair shortened as it was tugged upwards into a cute pixie cut. Then, she seemed to… brighten, just on the whole. Her mocha skin seemed to take on brighter color, looking more like a sun tanned lighter tone than her natural complexion. Her hair and eyes weren’t exempt. She brushed some hair from her eyes, but stopped as she watched it quickly brighten to brown and keep on going until it was platinum blonde. Her eyes felt funny - while she couldn’t see it, they took on an ocean blue shade. The last notable change, only visible because her hair was shortened, was how her ears turned pointed. That felt weird, to say the least.

The final change wasn’t to her physical body, but her clothes. Lydia’s tank top and shorts took on a new, almost metallic texture, and expanded in an almost liquid way, spreading across her body. It felt kinda like she was in a bath, but somehow more solid. Soon, everywhere below the neck was covered in the metallic substance, which quickly solidified to keep its new shape. It took the form of dozens of smaller plates, coming together in a suit of armor that hugged her figure tightly. While it wasn’t quite raunchy, Lydia groaned as she saw the shape of the breastplate - the standard fantasy ‘boob plate’, that was rather more sexy than it was practical. She was fine with armor, but did it have to be so sexualized?

Meanwhile, Samantha was undergoing a distinctly different change. Not unlike Lydia, she liked transformations - when they were stuff she knew would be temporary like this, it was exciting. She didn’t go looking for them but she wouldn’t complain at being on the receiving end like this (or if she could be on the giving end…). So she certainly wasn’t going to complain, especially if it ended up interesting.

She started out tall, but as the change took hold she dropped until she was the shortest of the group, dwarfed by Lydia’s new height. While they were less visible than Lydia’s, Samantha’s muscles also shifted, this time in the opposite direction - her amazonian definition fading and smoothing out, although she was still clearly an active athlete, just more wiry and lithe than tough and muscled. She was kind of disappointed by that; she liked being and looking tough. But she could give the new appearance a shot.

Samantha’s vibrant red hair darkened as it lengthened further and further, becoming a smooth midnight black as it fell in waves down to her hips. Her already notable curves deepened, as if to make up for her loss of height, her hips flaring out while her waist tightened. This, she could appreciate. She liked looking sexy, and she felt the figure more than made up for what she lost in muscles. Her ears pricked at the ends, extending out through her lengthy hair in fine elven points. She also felt significantly less tired than she had before; Elves didn’t need to sleep, just meditate.

Her clothes then changed, again in a rather different way to Lydia’s. Samantha had worn casual, feminine clothes, a denim skirt and a blouse with a deep v-neck to emphasize her bust. While it was hardly loose in the first place, the clothes seemed to tighten to her body as they darkened and changed in texture, showcasing her figure as they transformed. The soft fabric texture changed to a tough leathery feeling, which definitely felt interesting when it was spread across her body like it was. She could appreciate this style for her character - it showed barely any skin but it made damn sure that you couldn’t ignore her figure.

“I can’t say I didn’t expect this…” Brianna said.

Lydia stretched out, and struck a few more poses. “Wow… I’m so tall, and this figure is honestly kind of great. And no need to use a magic sword to be strong. Honestly, as far as transformations go, this one’s really cool.”

“You're not wrong,” Samantha said, looking over her body and feeling the leathers she was wearing, then her Elven ears. “If I’d known something like this was going to happen, though, I’d have given myself some more height. It’s nice for variety, but curvy and tall feels a lot better than curvy and short, in my opinion.”

“I don’t know how much Morgan would have cared if you had.” Lydia noted. “I don’t know about you, but I didn’t write my character having this kind of breastplate… it’s so impractical…”

“Morgan’s nothing if not consistent.” Brooke agreed.

Of course, the transformations wouldn’t stop at Lydia and Samantha. Brianna noticed Brooke’s skin starting to change colors at the extremities. “Looks like you’re up next, sis.” she said.

Brooke raised an eyebrow, and grinned a bit. “Look who’s talking.” she said. It was then that Brianna noticed something herself - as Brooke changed, so was she.

“What? I didn’t even make a character!” Brianna grumbled as she watched the purple creep up her skin from her fingers, up her hands and rapidly advancing up her arms.

Brooke, unlike her twin, actually thoroughly enjoyed transforming. In her line of work, with the kinds of villains she fought (and more generally, for anyone who was acquainted with Morgan), it was a fact of life. So why waste time grumbling and groaning when you could run with it? Admittedly, that was how she saw life on the whole, but it applied especially in this circumstance.

The purple creeping across her skin felt odd, as if wherever it spread grew burning hot, but somehow not painfully so. It wasn’t hard to guess what was going on. Brooke was playing as a Tiefling - a descendant of demons, or possibly of people who took some demonic pact for power. And looking over at Brianna, it certainly looked like she was having nearly the same transformation that Brooke was.

As the color spread across their bodies, the rest of the transformation didn’t wait. Their hair changed - the twins were redheads, with wavy shoulder length hair. Both of them had their hair grow out, down to the middle of their backs, while it shifted away from red. At first, Brooke thought it was turning black, but on closer examination it was actually taking on a dark blue shade. Looking at Brianna, she watched her sister’s - and by extension, her own - green eyes grow. The irises expanded and brightened, until her eyes were a solid green color without whites - and then the color changed, darkening and shifting shade until their eyes glowed purple.

Like their friends, their ears sharpened to points - but unlike the newly made elf and half-elf, that wasn’t the extent of their new racial characteristics. As the skin on her face and bottom started to turn purple, Brooke felt a strong sense of pressure in several places. She rubbed her forehead, and felt a twin pair of nubs on the top of it. The bony protrusions grew rapidly under her fingers, pushing her hand out of the way as they curled upwards and back over her head.

Meanwhile, she felt a strong pressure on her rear - her pants hadn’t been tight before, but they certainly were now. At first she thought it was some sort of change to her figure straining her clothes, but with a shrrrip sound, the back of the pants she was wearing gave out and her new purple tail burst from her behind. Brianna had a similar plight, and glared upwards. “You’re going to fix that, you know that Morgan!?”

As both Brooke’s and Brianna’s muscles smoothed out, the changes to their clothes finally occurred. While everything else had been essentially mirrored between the twins, this at least was different. Brooke’s character was a bard, so when her clothes clung to her body she wasn’t surprised. Her clothes merged together into a single garment - a colorful red and gold dress that emphasized her curves and had a nice neckline that showed off her admittedly average bust in a nice way. The look was added to by some nice red stockings and gloves, although the outfit did have a concession to practicality in the form of nice leather walking shoes instead of the heels Brooke would have preferred.

Looking over at her sister, Brooke saw that Brianna was getting a different sort of change, although similar. Brianna had always preferred androgynous, practical clothes - she didn’t much care whether it was masculine or feminine as long as it didn’t inhibit her movements and was reasonably comfortable. Morgan’s fashion sense, however, wouldn’t be so kind as to allow her to keep such an outfit. Her damaged jeans and shirt merged together much like Brooke’s clothes had, the sleeves pulling in at the shoulders while the legs of her jeans merged and expanded. Soon, she was wearing a nice, surprisingly modest blue and white dress - it was pretty and all, but not really Brianna’s style.

“It looks like you all are nearly ready for your adventures to begin~” A voice echoed in the heads of the group. Morgan had finally decided to talk to them, it seemed. “I heard that this was the kind of game where you play a role, but none of you looked the part! I had to fix that… with a few liberties, of course.”

“Now, the last time I did this I got some grumbling, so before you ask, don’t worry about how long you’ll be here. I’ve set things up so that for each week you spend in this little world of mine, only an hour passes in the real world. So you’ve got plenty of time to adventure your hearts out! I’ve got some fun stuff set up for you - sorry, Brianna, I’ll be borrowing your notes for a bit and making some tasteful additions… anyway, that should be it. Before you guys head out, have you got any questions?”

“Well, I’ve got one!” Brianna said. “Why did I transform?”

“Well, if you were just Brianna, that wouldn’t be very fun would it?” Morgan replied.

“I know that, but I didn’t even make a character! Why did I end up as a Tiefling Warlock?” While she didn’t have a character sheet on hand, she could instinctively feel what her stats and class and assorted other abilities were. The ‘Eldritch Blast’ spell was a bit of a dead giveaway as to the class.

“Oh, that’s easy.” Morgan said. Brianna couldn’t see her, but she could hear the dismissive wave in her tone. “I had to get creative with you since you didn’t have a character. You’re Brooke’s twin and she’s a Tiefling, so obviously you have to be too. And you’re a Warlock because that way I get to be your patron! I skimmed the book a bit and that seemed fun, but it’d be boring to just use the types of magic that are in the book. So why don’t you and I cook something up together, hm? Tell me what kind of magic you want~”

“Do you even know how to play Dungeons and Dragons? How do you plan to run it?” Brianna asked. At this point, it was more just venting annoyance than anything. Nothing could change Morgan’s mind but herself.

“I’ll be fine, it’s basically just telling a story, right? How hard can it be? Anyway, do you have your magic in mind? I want to get this rolling…”

Brianna rolled her eyes, but she did have something in mind. “Well, you’re you. If you’re going to be my patron, it makes sense to take something in line with how you usually act, right?”

“Oh, I like where this is going,” Samantha said.

“So how about transformation magic? The sort of spells that let me do what you usually do, since while we’re playing a game I might as well see what the other end of that looks like.” Brianna said.

“Sure, that sounds fun~ Anything else before we discuss the price you’re going to have to pay for it?”

“How about being immune to being transformed myself?” Brianna asked.

“Sure.” Morgan said.

“Well fine, then what about-” Brianna started going into her backup before realizing Morgan had agreed. “...You know, I figured you wouldn’t go for that. Had your fill of transforming me for one night?”

“Well, you see, that second part is a big deal for the kind of game I plan to run…” Morgan started. Brianna sighed. “So we’re going to need some drawbacks. Now, I could pick… or I could let Brooke, Lydia, and Samantha pick their own conditions for you. Which is what I’m going to do, if that’s not obvious.”

“Bimbofy her!” Samantha said instantly, before anyone else could respond. “I think that’d be fun, having a sexy ditz with transformation magic~ And it’d help her loosen up and get in character, don’t you think?”

Brianna groaned loudly. “Oh come on…” she muttered, but of course, the changes had already started again. She hadn’t even gotten used to having a tail yet, and she was already layering on another transformation, and one of the ones she hated the most at that.

The first noticeable change was again at her fingertips, and again had to do with her skin - her purple skin was brightening in shade, becoming a bubblegum pink color that crawled up her arm. She could live with purple but pink? That was so cute- annoying, actually. She groaned as she noticed the stray thought. The mental transformation had already begun.

The new coloration wasn’t the only thing, though. Her clothes changed, becoming looser and larger. For a second, she was confused - they usually would become skimpier for this kind of change, wouldn’t they? But when her bust suddenly ballooned outwards, the change was more clear. It was skimpier - it had simply grown so that when her breasts turned into beach balls they’d be straining the dress rather than shredding it. She stumbled backwards as her buttocks followed suit, trying not to fall over. She felt at her breasts experimentally, and bit back a moan as she felt how sensitive they were in spite of their size. Titties feel so- she cut the thought off, but it was a losing battle she was fighting.

The trio who were done with their tfs watched Brianna’s progress with fascination and interest. “So… I know you’re rivals and all, but why…?” Brooke asked, although she didn’t seem overly mad.

“Oh, because it’s hilarious and sexy.” Samantha answered. “I’d never push this on her in a normal situation, but we’re already in a game, so why not have a good time? It’s not like she can get herself into real trouble for her stupidity or horniness, here. She’s always wound so tight, a bit of air in her head will do her good.”

Lydia looked over Brianna, watching as the Tiefling continued to bimbofy rapidly - and particularly at the breasts straining against her dress, and the plunging neckline that showed them off. “...Sexy is certainly right.” she said, blushing a bit.

“She could probably stand to loosen up a little, you’re not wrong about that.” Brooke conceded.

“Hehehe~” Brianna let out a high pitched, feminine giggle. Then coughed. “That’s like, real nice of you all to be on board with this…” she winced a bit as she noticed the ditzy speech pattern starting to leak into her voice. The transformation was progressing on, with the majority of her skin having taken on the bubblegum pink color. Her hair wasn’t exempt from the color change, although it instead brightened up considerably, from a more navy shade to almost neon blue. As she watched, pink highlights laced into it - and it grew out even more, from the middle of her back on down, flowing past her bottom and nearly to the ground. “Oh, it’s like, so sexy now…” she said, her cheery words contrasted by the exasperated tone she used.

She couldn’t see it, but even her eyes were changing color, purple changing to pink as her mind was losing the battle. She felt her figure changing again, her hips pinching even more and her waist expanding to match her bottom. While Lydia and Samantha were curvy now, her own hourglass was beyond the realm of realism - it was the sort of exaggerated sexy figure that was only possible in a fantasy world. And she was finding it difficult to see that as a negative. She found herself unconsciously flaunting her new curves and assets. Lydia and Samantha were eating the eye candy, and she was happy to provide~

It was as if her intelligence had drained away and into her tits. But that didn’t matter, really. She was a sexy demon girl, she didn’t need to like, know things! She just had to cast her patron’s spells and get fucked by cuties~ Brianna sauntered up to Samantha, grinning. “I see you looking~ Wanna head somewhere private, cutie? I can give you a nice show~” she said, pressing her impressive bust against Samantha’s and licking her lips.

Samantha nodded enthusiastically at first, before looking over at the other two glaring at her. “...Oh fine… sue me for wanting to enjoy it, why don’t you…” she muttered.

“Aww, are you two jealous?” Brianna teased, looking over at them. “I’ve got another hole for Lydia there, and I’m sure this cutie can take two Tieflings~”

Brooke walked over, and Brianna thought for a second she was accepting, before she actually talked. “While I’m sure that’d be fun, I think this is enough…” she said. “So you said conditions, not drawbacks, right Morgan?”

“As long as it’s not just ‘she’s not a bimbo’, go for it. This is such a rare transformation for her, it’s pretty satisfying~” the disembodied voice of Morgan said.

“Right.” Brooke nodded. “Well then, I say that whenever she has sex, she gets her mind back for a full 24-hours.” she said. “Oh, and she has a one hour grace period to get laid starting now, before she goes back to an empty head.”

“Your wish is my command,” Morgan said, “That’s 24 hours for you, mind, not for me.”

“Awww,” Brianna pouted. “It’s so nice not having to think…” she said. Shortly after she said that, though, she suddenly pushed Samantha to the ground. “Sam, you know I’m in a relationship right?” she said, her voice a lot less bubbly now than it had been a second ago.

“Can’t blame me for trying! You turned out so hot…” Samantha said, although she was smiling still.

Brianna, in response, strolled right up to Lydia and pressed herself against the half-elf paladin. “You’re also in a relationship, you know. I’m sure David would love to know you went at it with his old girlfriend.” she said. There wasn’t too much venom in her voice when she said it - this wasn’t the first and wouldn’t be the last time they had one of their little spats, and it had been short lived enough that she didn’t mind.

“It doesn’t count if we’re transformed.” Samantha muttered.

“Thanks for that, Brooke,” Lydia said. “I love the figure, I have to admit, but I love it more when it’s my Brianna in there.” She said. Brianna smiled and pressed a bit closer - giving Lydia an eyeful, with their present height difference making it easy for her to look into Brianna’s cleavage.

“No problem,” Brooke said, “Now, we’ve got one more, don’t we? What’s your condition?”

Lydia thought about it for a bit, then looked down to look Brianna in the eye. “I think I’ll add on to Brooke’s some. While I’m sure that we’ll be doing enough to keep the timer running, what with that body… I’ll make it easier, and say that masturbating counts for it, just in case we’re separated for a bit.”

“Aw, doesn’t that make it a bit too easy?” Morgan said, “But fine, I did say you could give that kind of thing.”

Brianna was suddenly quite sure that Morgan would be structuring some encounters to split her off from the others and make it impractical to take care of herself. But that didn’t mean she appreciated Lydia’s gesture any less.

“Thanks for that,” Brianna said, getting up on tip-toes to kiss her girlfriend. “Now, I think that deserves to be repaid somehow…” she let her hands roam across Lydia’s body - it was armored, but there were parts where she could feel the muscle underneath. “How about we find somewhere private and you can get that timer going? Might as well break this body in right…”

Lydia blushed a bit, but nodded. “I… yes, I’d like that…” she looked to the others.

“You lovebirds get to it.” Samantha said.

“We’ll wait here and try to figure out where we’re going.” Brooke added.

Lydia nodded her appreciation, and swept Brianna up in her arms. She usually wasn’t this much stronger than she was, so she was going to take advantage of that while she could.

Over the next hill they found a nice looking spot next to a stream that was running loud enough to mask the sounds they’d be making. As Lydia laid a giggling Brianna down on the ground, she started to pull at a strap on her armor, when it suddenly seemed to vanish from her body and was piled neatly beside a rock. Something to thank Morgan for, when it wouldn’t be a mood killer.

Brianna gently pulled Lydia down to the ground with her, and their hands started to roam. Brianna undid the strings of the tunic that Lydia was wearing beneath the armor, while Lydia took a few handfuls of the Tiefling’s breasts. “I have to say… I love your normal body, but variety is certainly nice…” Lydia said softly, nuzzling her head against Brianna’s chest.

Brianna couldn’t help herself as she moaned at her girlfriend’s hands on her bust. Even with her mind back to normal, her breasts were no less sensitive than they had been as a bimbo, and each of Lydia’s fingers felt like they sent sparks of pleasure through her body. “Ehehe… the same goes for you… I can appreciate these muscles a lot…” Brianna said. She reached a hand around to grab Lydia’s bottom, and squeezed.

Lydia made a surprised sound, and smiled. “Two can play at that game…” she said, reaching around and grabbing. Brianna made a surprised sound as well - but then laughed. “What’s so funny?” Lydia asked.

“I think you were going for my butt… but you grabbed my tail…” she said, struggling to get the words out between giggle fits.

“Ha! I’ll be a bit more careful from now on. Unless I want to use it for something. I wonder how flexible that tail is…”

The two would be gone for well over an hour. Brooke and Samantha figured out where they were quick enough, finding a marked map in the backpack and asking a few questions of Morgan in her role as ‘dungeon master’. Eventually, the two went to look for Lydia and Brianna… which, as they berated the two to come back to the road, led to their first encounter. The adventure had begun, and it’d certainly be a session to remember...
