Commission
——
Another day arrived near the Expansion Mansion dungeon (as it had come to be called). The female adventurers who spent the night there had since waddled back to the guild, reported their findings, and gone to rest. Thus began the usual morning lull. Adventurers who planned to go in that day usually waited until the afternoon, thus having time to plan their route and mentally prepare themselves.
However, that meant the dungeon was uncrowded at this hour. So, two adventurers had planned to strike at this exact moment.
Cinder Fall was a jumbled mix of classes, relying on magic and conjuration. She could pelt enemies with magic from a distance, use a bow when needed, or slice through someone with a sword if she felt like it. Her outfit reflected this with a snug, yet elegant, red dress with slits on both sides. The dress would flow around her, but leave her legs open for greater mobility. This also allowed her naturally thick thighs to remain partially exposed.
Clementine was a rogue who usually got the jump on targets while Cinder distracted them. She wore a corset of adventurer badges that she collected through her travels. It supported her bust, thrusting her chest forward and accentuating its plump size. Her midriff was left exposed before her shorts began. These were so small that they hardly covered anything, instead squeezing her hips and supporting her butt.
“The one downside is we haven’t found our tank,” Cinder murmured as she looked at the updated guild roster. “These ones don’t talk to us, some of these are currently sleeping, and her…ugh, I’m surprised she even wants to explore. She’s as fat as a cow.” Cinder tossed the roster aside.
Clementine chuckled as she fiddled with one of her stiletto knives. “True, so very true. Many of our…companions are so eager to bloat themselves into sacks of fat. I want a little curve, is all.” She seemed calm, almost bored, but in reality, she was frustrated. The loot from this dungeon was incredibly valuable, but everything she had claimed would make her obese. So, it all wound up being sold to the guild. “What we need is a newbie to pull agro.”
“Um…excuse me?” A soft voice fluttered. The two turned and saw a blonde girl with small goat horns on her head. She was clearly new to the place, with simple leather armor hardly more durable than street clothes. “I heard you need a…newbie. Um, could I volunteer for that?” She smiled awkwardly.
Cinder and Clementine glanced at each other. This was too good to be true.
Clementine was out of her chair first. She wrapped an arm around the newcomer’s shoulders. “Well, of course you can!” She cheered and nuzzled her new patsy. “My companions, Cinder, and I were just about to head to the dungeon! Unfortunately, we were missing a third! It’s safe to travel in groups, but three is the sweet spot. Less sharing the reward. Ooh, I’m Clementine by the way!”
The new girl was flustered at the close contact. “O-oh, I’m Aleta! I just got here, but I heard the dungeon was a good place to earn coin. I’ll do my best to help!”
Cinder got up and tucked into Aleta’s other side. “Then you heard right. Let’s not waste any time, come on, come on.” She started to drag Aleta along with Clementine out of the guild and toward the mansion…
——
Cinder and Clementine had remained kind on the trip to the dungeon, but their attitudes shifted once they got inside. They insisted that Aleta went ahead of them despite being the newbie. They just continued to say that it’s a good experience and that no one had died or been injured in this dungeon. Still, it was nerve-racking for Aleta to walk blindly into the dark halls. She hardly mustered the courage to enter any of the rooms, and she was anxious whenever she opened a chest or cupboard.
Eventually, this nervousness seemed unwarranted. The group had encountered no traps or monsters.
Also, no treasure.
“Another empty room.” Cinder sighed and kicked over an empty chest. “Dungeons are supposed to restock themselves. Don’t tell me this one has keeled over on us.” She tapped her foot, her heels clacking loudly.
Clementine seemed more bored than upset. “I’m curious why no monsters have shown up. The main thing this mansion has are tentacles. Don’t tell me they’re scared of little ol’ me.” She murmured, again playing with her stiletto. Clementine had encountered the tentacles plenty of times, but they had never taken her down. She was quick enough to stab them each time, so it made sense for them to avoid her.
Aleta laughed nervously. “W-well, it’s a peaceful first time for me.”
“Shut it.” Cinder scoffed. “I don’t come here for fun. I come here for money. It’s a wasted day if we leave empty-handed.”
Just then, a nearby wall began to rumble. The wood seemed to stretch and twist. The boards didn’t split apart so much as they morphed into a new shape. A doorway opened up, and it led into a cave-like passage.
This was a fresh door, so new that the room beyond it hadn’t been given proper shape. Still, it was a passage wide enough for them.
Cinder grabbed Aleta by the shoulder. “Now’s our chance. Discovering a new area pays like crazy. Not to mention what we’ll find there, so move it!” She shoved the younger girl through the doorway.
Only for the floor to drop out from beneath her.
Aleta felt weightless as she suddenly fell. The drop continued roughly twenty feet before she suddenly stopped. It wasn’t a rough or painful landing, instead it was just an abrupt stop. Aleta had landed on…no, in something. She couldn’t see it, but the substance felt somewhat wet. Not a liquid like water, but something semi-solid.
“Eep!” Aleta squeaked as whatever she landed in started to move. She reached her hands down, only for them to be pulled into the substance. “What is this…a slime?! H-hey, I could use some he-EEP!” She squeaked louder as she felt pressure between her legs.
The slime easily flowed around and even through the fabric of her panties. Her crotch tingled before a strong flow of slime forced itself into her womanhood. The tingling sensation traveled inside of her with the slime. At the same time, her belly began to bulge outward. The round mass quickly tore through her cheap armor, revealing pale skin.
Aleta was helpless to stop the flow, and her trapped hands prevented her from reaching toward the walls. Although the walls might not even be close to her. She could hardly see past the tip of her nose. She was stuck in the dark with the slime that eagerly invaded her body.
Aleta wanted to open her mouth to scream for help again. She parted her lips, but a moan escaped instead. Her thighs trembled, and her core burned brightly. Part of her tried to will her hips lower. She wanted to push them deeper into the slime.
Sensing this, the slime began to fill Aleta faster. More than her belly began to swell. Her thighs thickened, bulging until they squished together. Her hips rolled out as smoothly as rising dough. Her butt cheeks thickened until her leather pants were torn asunder. More fat was stacked into her belly until it was beyond her arm’s reach. Her sides were lined with rolls until there was no space to share. They started to rejoin in one large, outward curve, adding to Aleta’s spherical shape. Her arms swelled into useless, pudgy accessories, quivering with fat from her shoulders to her wrists. Breasts became rounder and heavier, resting atop the belly beneath them and rising to the extra chins above them.
This growth continued on and on. Any semblance of slenderness vanished from Aleta, as did any ounce of fear. All that melted away as Aleta was filled with more slime. She bit her lip, moaned unabashedly, and relished all her new curves. The slime seemed just as eager to fill its vessel. It brought incredible pleasure and tingling to everywhere it stored itself. As the ooze reformed into fat, it continued to radiate magic, bonding itself to Aleta. It packed more and more of itself, raising the pleasure from ecstasy to unimaginable nirvana.
Aleta felt pressure build through her body. “Ooooh…I’m so full…but it’s so good…so good…sooo gooooood!” She closed her eyes, tensed, and climaxed!
And burst.
One quick pop, following right after orgasm.
Things were silent for a moment before Aleta gradually came to consciousness. “Huh… is it over?” She slurred and tried to sit up. However, she found herself unable. She tried to move and felt herself slide forward. “What’s going on?” She focused and gradually began to see in the dark.
“What the?!” Aleta exclaimed as she regained her senses (and acquired a few more). What she saw was not her body. Instead, she saw herself as a small glob of slime. “I…um…this is so weird.” She murmured and rolled about. She had no idea what to do. If she managed to get out of the dungeon, then what would she do? It was already hard enough being a demon, but being a slime?!
In Aleta’s frantic rolling, she ran into other puddles of slime. She hardly noticed, but her body melded with those, and her gooey form grew larger. With this size came more clarity. Aleta stopped rolling and refocused on herself.
“I got bigger? Hmm…” Aleta focused and reached out. A small tendril emerged from her and touched another puddle of slime. She began to suck it toward her like the tendril was a straw. Her body grew larger. “I think I’ve got an idea!”
Aleta set about absorbing all the slime in the room. Her body regained more mass, and it gradually began to resemble her former self. By the time the room was cleaned of slimes, Aleta had reformed.
Albeit a semi-transparent, moderately pudgy, taller, orangish-pink version of herself.
“I look sort of like my old self, but I think I absorbed too much slime. I wonder if I can shed some of it?” Aleta closed her eyes and concentrated. She tensed her chest and puffed her cheeks. She felt her body begin to vibrate until.
FWOMP!
Aleta opened her eyes to see the excess mass shifted to her belly. What was once flat, then curvy with slime, was now a bloated orb wider than the rest of her body. Aleta did the closest thing she could do to blush as she reached out to touch her belly. “Oh…not what I was thinking, but that’s sort of cute. Maybe if I…”
Aleta repeated the process. She focused, made a mental image of where she wanted the slime to go, and…
BWMP! FWMP!
This time it took two bumps, but Aleta opened her eyes and saw the mass had transported to her breasts. This made her much more bashful as she slid her fingers across these curves. “Eheh…sort of embarrassing, but I like it. It’ll be a bit hard to see and move, though. How about I just…there we go!” Aleta pressed her hands down on her chest and, with a little thinking, reshaped her form into a more hourglass one. She maintained the expanded bust, a little chub on her belly, but now boasted doorway-filling hips and a round butt. “If only I had some clothes to go with this body. Slimes are usually naked, but they can’t think about that.”
Just then, a wall slid open. Beyond it was a revealing dress on a hanger. Crystals at the ceiling of this tiny room shone down like typical lights, highlighting the object.
“That’s way too convenient!” Aleta exclaimed and looked around her. “Did the dungeon do this for me?” The walls shook subtly, as if to confirm. “That’s pretty nice. I heard dungeons are alive, but I never thought they’d be…well ALIVE!”
Aleta slid toward the dress and put it on. She had no appraisal skill, but even she could notice the material fit over her slime instead of sinking into it. The material was wax-coated to ensure it wouldn’t absorb moisture either. Aleta could wear this just as easily as she wore her former clothes.
It also came with a whole host of buffs. Improved vision, viscosity control, magic EX, and a social ward to fend off any attacks that would usually harm slimes.
Aleta couldn’t sense this, but she felt the bump in power. She smiled and looked around her again. “Thank you so much, Mister Dungeon! If you are a mister, that is. Either way, I love it!” She did a twirl as the walls shifted again. This time, a door to a new hallway appeared, lights following down as if to direct Aleta.
Aleta followed to what looked like a dead end. A closer peek revealed a thin crack, revealing a room beyond it.
Cinder and Clementine were there. Both seemed none too worried about their abandoned comrade. Aleta leaned closer to listen to what they were saying.
Cinder currently admired a ring on her finger. It had a bright red jewel and a golden band. In any other dungeon, one could imagine it being cursed or boasting a simple buff. In the Expansion Mansion, it naturally made Cinder’s breasts as large as watermelons. Her other hands caressed the curves and gave shameless squeezes.
Clementine had a bronze bracelet adorned with pieces of topaz. There was no telling what benefit it had other than widening her hips and enlarging her ass. Still, she seemed pleased and caressed herself just as lovingly as Cinder did.
Honestly, Aleta could tell both looked pretty excited. They’d likely be exploring each other’s bodies any minute now. Aleta didn’t think long on that. She instead realized that her assets were much more impressive than those two. ‘Was I the one who lucked out?’ She thought and refocused on listening.
“Finally found something I like.” Cinder fondled her chest and laughed heartily. “This new area is sparse, but it’ll fill out over time. We just need to make sure no one else finds it.”
Clementine grinned sadistically. “We can just cover up the pit our useful idiot fell into. Anyone who tries to wander in will vanish!” She chortled and smacked her right thigh. “People will think they got bored and wandered off to find a new dungeon. This one is getting a bit stale anyway.”
Aleta huffed from her hiding place. “These girls are too cruel! No way will I let them try to hurt anyone else!” She pushed her body against the crack in the wall. Her slime form easily passed through. Her new dress was pulled along and reaffixed to her as she emerged on the other side. “Stop right there!”
Cinder and Clementine looked at Aleta initially with surprise. They then began to laugh hysterically.
“So you managed to get yourself turned into a slime? Of all things, a slime!” Cinder laughed so hard that her breasts nearly leaped from her dress.
Clementine was equally tickled. “Hey, it’s pretty fitting! A newbie adventure and the lowest of dungeon mobs? Practically the same thing!” She threw her head back, laughing so hard tears welled in her eyes.
Aleta puffed her cheeks up adorably. Being abandoned was one thing, but being teased directly to her face?! She was about to open her mouth before tentacles sprang from the walls. They quickly bound Cinder and Clementine by their wrists and ankles, pulling so the girls were restrained in an X pose.
However, the tentacles didn’t immediately rip through their clothes or try to fuck them. More tentacles had appeared, but they hovered in front of Aleta. One pointed at her before it turned and mimicked the motion toward Cinder and Clementine.
“Me? But what am I supposed to do?” Aleta asked despite following the tentacles to the restrained pair. They were saying all sorts of rude things and curses, but Aleta tuned them out. Again, the tentacle gestured at the girls, but it seemed to point right to their mouths.
Aleta tilted her head to the side. “I still don’t get it..oh, OH! I think I see!” Aleta reached out, stuffing a hand in each of the girls’ mouths. Just as easily as she had reshaped herself earlier, Aleta manipulated the slime to flow down her captors’ throats. It was as easy as pushing a button, as simple as tilting a cup. Aleta pumped the ooze that was her body into Cinder and Clementine, whose bellies immediately began to swell with supple fat.
“Am I doing this right?” Aleta looked at the tentacles, which bobbed up and down. “Great! Though, what do I do if I run out of…well, me?” She asked before the tentacles poked into her back. It was like a hose had been attached to her. Two tentacles worked in tandem to fill Aleta with their fluids, which quickly dissolved into slime. This felt much like a tickle to her, but it kept her fully stocked.
Maybe a little more. Aleta’s curves were expanded. The pace was slow as she steadily filled Cinder and Clementine, but it was enough to keep her growing instead of shrinking.
Cinder and Clementine’s stomachs swelled until they reached nearly three feet in front of them. The domes grew broader and denser before they rapidly digested the slime inside. This sent the extra mass through the rest of their bodies. Cinder’s breasts began to swell at a faster rate, and Clementine’s lower body took on broader curves more quickly.
Both women were getting fatter by the second. They rapidly sailed past their desirable sizes and into the morbid obesity they had hoped to avoid. Thick fat took hold across their bodies, simple curves were bloated and distended with rolls packing away where they could. Bodies tuned for adventure (and pleasure) were now hardly suited for waddling. It would still be possible, but it would be a struggle.
Cinder would struggle to use any of her former skills. Her arms were too heavy to properly aim spells or wield bows or swords. Heavy shoulders sloped into thick upper arms and down to puffy forearms. Her breasts became large enough that she’d never be able to see her feet past them. If she somehow managed to draw a bowstring, it would surely strike the side of one massive breast. It was simply impossible to work around globs of fat broader than her shoulders used to be. Her belly softened considerably and draped itself over her thighs. This fat flowed onward until it started to roll over her knees. Her hips gradually thickened, but it was only a proportional increase. Her butt was thick but certainly not as round as it could have been. Finally, her legs thickened into more barrel-shaped pillars than lusciously curvaceous thighs.
Clementine filled out oppositely. Her hips made a tremendous leap in size, her butt and thighs growing exceptionally, too. These assets rapidly took on broad, arching curves. They managed to pop with a much rounder shape than Cinder’s purely thick lower half. In exchange, her upper body was not as voluptuous. Her belly was certainly impressive and round, growing by the second, protruding nearly as far as Cinder’s, too. Clementine simply lacked as thick arms, broad shoulders, and a full chest. Her breasts were nowhere near as round, instead relying purely on her upper belly for support. This lacking didn’t stop her face from rounding, however.
Both women continued to grow as Aleta was constantly supplied with new slime. They glanced between each other and their bodies. They had worked hard to avoid winding up like this, and there was a chance they wouldn’t be able to lose this weight. Any weight gained in the dungeon tended to stick. Whether that was because the ones bestowed it refused to lose any or were physically incapable…no one knew.
Either way, Cinder and Clementine were burdened by their new weight. The tentacles released them, but they still fell to the floor. Their bodies were bloated and naked, their clothing having burst around their new curves. They were left in a stuffed daze. So full and exhausted that they couldn’t levy curses upon Aleta.
Aleta hardly paid attention. She turned to face the tentacles that helped her. “You’re the greatest! I appreciate all the help!” She giggled and patted each tentacle on the head. The tendrils responded by nuzzling into her hand. They started to wave about shortly after, but… “Sorry, I don’t think I understand that.” She smiled nervously before the floor began to shine beneath the slime and her bloated companions.
The light turned to a bright flash. It gradually cleared to reveal that Aleta, Cinder, and Clementine had been teleported to the guild hall. That was when Aleta realized she might be in trouble. Not only had she been turned into a slime, but she had immediately used that power to attack two adventurers.
‘What if I turned into an evil slime without realizing?!’ Aleta looked around frantically. This caused her gelatinous body to wobble, noisily slapping together. It was loud enough that she couldn’t hear Guild Girl on the other side of the desk.
“Ehem!” Guild Girl cleared her throat, which caused Aleta to freeze. “Welcome back! I see your first dungeon dive was interesting.” She smiled and started to sort some forms. She was still adjusting to her encounter with the dungeon milk, so seeing these papers past her breasts was always an issue. Her enlarged ass also took up two chairs, but still hung over the sides, too.
Guild Girl also struggled to focus because she didn’t want to look away from Aleta. ‘Slime transformation? That’s a new one.’ She looked around Aleta to see Cinder and Clementine. ‘But it looks fun!’ She started to smile and stood up.
“Aleta, part of every dungeon dive is the report filing afterward. You’ll be compensated for any information and materials you donate to the guild, but you’re a special case. Could you…show me how this new body works?” Guild Girl asked. She was tempted to roll over the counter. ‘I wouldn’t mind inviting her to my room either. I’ve got plenty of ideas.’
“Oh, sure!” Aleta innocently thrust her hand into Guild Girl’s mouth. That caught the woman off guard, but slime had already started to pump down her throat.
Guild Girl’s already distended belly stretched further. The round shape pushed up against her breasts and rested atop her thighs. This continued until it looked like she had swallowed a beach ball. Aleta retracted her hand, and Guild Girl immediately grasped her belly.
“Oof. Oh, ooooh~” Guild Girl began to moan. Her skin was tingling with pleasure. That pleasure sparkled brighter when she pressed her fingers into her plump stomach. “Slimes tend to have strong control over their forms, even when divided. Have you noticed or been able to perform this ability?”
Aleta tapped her chin in thought. “I did for myself. I don’t know if I can do it with others. Let me see.” Again, Aleta acted before thinking or properly warning Guild Girl. She focused on the slime in the woman’s belly and pushed it downward.
Guild Girl managed to grab the table before falling backward. The sudden weight and mass shifted toward her butt cheeks had thrown her balance off, but the sensation was pleasant. The woman widened her stance and shook her rump. Her butt cheeks, now doubled in size, bounced and noisily clapped together. “That’s quite the mastery you have, and only after a short time. I hate to be a bother, but could you move just a bit to my chest? I’ve been trying to build up an hourglass shape.”
“You’ve got it!” Aleta shifted some of the slime, enlarging Guild Girl’s breasts enough to pop a button on her blouse. ‘Seems I’m not in trouble. That’s a relief.’ She thought before a sizable bag of coins was dropped on the table. “Eh?”
“Your payment, thank you for your generous contribution to the guild. We look forward to your adventuring career with us.” Guild Girl grinned and winked. “Also, it seems the others want to meet you.”
Aleta turned around to see that nearly twenty other female adventurers had gathered. Each was expanded in their own way, a mixture of enchanted equipment and likely pounds picked up organically through their diets or the dungeon’s tentacles. Aleta was flustered as she stared. Despite that, she took her reward money and entered the fold of her fellow adventurers.
Cinder and Clementine were left on the floor, still dazed from their expansion. Hardly anyone paid them mind. Some threw a teasing barb or nudged their fat with a boot or a jabbing finger.
The true star of the day was Aleta. She was already being inundated with offers to join adventuring parties or head to private bedrooms…
THE END
