CW: Weight gain, stuffing.

Muffet the spider decides that in order to help her bakery succeed, she'll need to make some BIG changes. Get it? Big changes? Because she gets fat?

Commission for and this was an absolute joy to work on. The idea was hilarious and fit with Undertale's tone perfectly and I think Muffet doesn't get nearly enough fat focused stuff on her. ^^ Enjoy!

===

“Oh come on...there’s no way they were that bad!” Muffet the spider groaned as she watched a human rush out of her bakery having taken a single bite from one of her cupcakes, the man at least five seconds away from gagging on it as he dropped it and fled, “Fine! You’re not allowed in here again!” She snarled, “Ungrateful...urrrrgh…” A sigh came from the arachne as she walked over to pick up the treat, shrugging and popping it into her mouth, “Five second rule.” She said to herself before walking back over to the counter, setting her head down on it as all five of her eyes looked around at the empty bakery and letting out another deep sigh of frustration and annoyance, but mostly annoyance.

"Why don't these humans appreciate my baked goods?" Muffet thought as she looked over at one of the donuts sitting in the glass display case, reaching one of her arms in to snatch it and take a bite.

"I had monsters beating on my web lines to get my treats in the Underground. What am I doing wrong up here? Did I lose my touch somehow?" She asked herself. It had been almost a year since the barrier separating the Human World and the Underground had come down with many monsters choosing to leave and explore their suddenly new surroundings. Muffet had been one of them and chosen to continue with the craft that she knew best, but was now obviously finding some difficulty, "Hmmm...perhaps a fourth pair of eyes might be good to have in this situation." She said, opening up a small book underneath her counter and flipping through the pages.

***

"Huh...I was expecting something a bit more extravagant." Muffet commented on the somewhat quaint looking house present before out in the suburbs. The only thing fully indicating the presence of who she was there to see was that of a purple Delta rune based knocker on the front of the door. She slowly nodded and psyched herself up before reaching an arm up to use it. A short time passed before the door clicked and opened up as a tall, white-furred goat-like being looked down before a smile crossed her face.

"Why hello there." Toriel said, "How are you doing today?"

"Hello, Miss Toriel." Muffet said, slightly nervous at seeing the motherly monster in the flesh, "I'm, um, Muffet." She said, "I'm actually a bit of a fan of yours and I wanted to come by and-" She abruptly cut herself off and facepalmed, "Shoot, I just came off like a complete creeper by saying that, didn't I?" Her embarrassment suddenly molded into confusion when the Boss Monster giggled and she looked back up.

"It's alright, my child." Toriel smiled and stepped to the side, "Please, come in and we'll discuss what you wish." She nodded before walking inside, the spider following her in, "Can I get you some tea?”

“Yes, that would be nice.” Muffet looked around the whole household as she walked about. It was very welcoming with warm colors and soft furniture, matching the personality that she’d been greeted with at the door.

“Feel free to take a seat if you want.” Toriel smiled as she walked back into a nearby kitchen. Muffet did so, the cushiony chair feeling comfortable as she waited for a few minutes. Toriel returned shortly after with two cups of tea and a small plate on a platter that contained a pair of small cakes.

“Thank you.” Muffet nodded as Toriel handed her one of the cups, “Mmmm...that smells good. Is that some snail tea?”

“I figured you might like it.” Toriel beamed as she sat down as well, “So, what can I do for you?”

“Well, I opened up a bakery about a month ago and business has been...not great.” She said, the slim digits of her fingers running along the handle, “Some of the monsters that I had come to my bake sale in the Underground come by but I haven’t had a single human stick around to try out anything else. They just kinda’ cut and run after seeing me.” She took a sip from the cup, “But everything tastes fine when I eat it and monsters still like them. What do you think I’m doing wrong?” She asked.

“Hmmm…” Toriel sat back in her chair, still holding the teacup in her paws as she looked to be in deep thought, “Well, I must say that I’m not exactly what you would call an expert in business. I’ve never really considered selling any of the things I bake. The only thing that I could see you potentially refining would be advertising. But you also say that humans run from your bakery?”

“Yeah.” Muffet nodded as she drank from her tea and took a bite from the small cake, “I heard that a lot of humans are afraid of spiders. Do they think I’m going to eat them or something?”

“As much as it pains me to say, that could be a possibility.” Toriel sighed, “Frisk is doing as much as possible as an ambassador between humans and monsters but they can only do so much. It has only been a year after all.”

“Well, I don’t think that I have that long. I need some solutions now.” She took another bite from the cake, “Maybe I could try hiring that angry yelling man I see on TV, the one with wrinkles on his forehead? Maybe he could really-” She abruptly cut herself off, “-this cake is so delicious! Sorry, I just had to compliment.” The romper-clad spider smiled.

“Why thank you.” Toriel nodded, “It’s a favorite of mine and most of the monsters and humans that come see me.”

“I can see why. The flavor in this is incredible.” She went, finishing up the cake, “Mmmm…” She went, bringing her hand up to lick some of the crumbs and excess frosting off. While she did, her eyes flitted subconsciously about the room. She found herself focusing on a sign hanging just in the entrance of Toriel’s kitchen with a white chef’s hat with some stylized text reading ‘Never Trust A Skinny Chef.’ She looked the decorative placard up and down before she got up and walked closer up to it, “What does this mean?” She asked, pointing up at it.

“Oh?” Toriel asked, setting the tea down and picking up her reading glasses, “Oh, that.” She smiled, “Asgore got that for me after I moved in here. It’s apparently a fun human saying.” She let out a slight giggle, “And he did always have an appreciation for my curves.” She said, a light blush coming over her white muzzle.

“Never trust a skinny chef…” Muffet repeated, all of her eyes locked on the sign as she processed what Toriel had told her. A large, toothy grin came across her face as she got an idea in her head before she flipped around to run over and give Toriel a big hug, "Thank you so much, Miss Toriel! You are the goat! The G.O.A.T., that is!" She cheered, "Sorry, I have a lot of preparation to do, come see me the next time you get a chance!" She clapped her hands together and then quickly took off out of the house, stopping only to politely close the door behind her.

"Oh my...what just happened?" The dazed Boss Monstress asked herself.

***

A day later, Muffet put her hands on her hips as she looked at the impressive spread of sweets in front of her while she rubbed two of her upper hands together.

“Mmmm...I have to hand it to these human bakers. These pastries smell absolutely delish.” She grinned, “And every single one of them are mine~” She went with a sing-songy tone as she walked up to them, “Hmmm…” Two of her hands darted around as she seemed to have trouble deciding just which one to actually start eating. She eventually just shrugged and snatched an eclair and a chocolate cornette and stuffed them into her mouth one after the other. The moment that each one went into her mouth and collided with her taste buds, her eyes blinked rapidly as she savored the flavor. Despite having lived above ground for a decent amount of time, Muffet had never actually sampled anything from the bakeries and was now kicking herself for not doing so as the flaky crust of the cornette and not-too-sweet icing of the eclair made her totally giddy and wanting to have even more. Six hands shot forward and moved across several dishes as fritters, donuts, muffins, and cupcakes of all kinds were snatched up and put into her toothy maw, the sugary confections causing a chain reaction as her neurons fired off with total delight.

"~Tasty tasty treats for me, all of them in my belly~" Muffet thought as she kept up her feast, unaware that she'd eaten almost half the spread. As the wiry-built baker went to drop another donut into her drooling mouth, she stopped momentarily as she felt a sudden sharp pinch come from her middle. Looking down with an annoyed stare, she found that her normally slim belly had become distended and had started to push up against the fabric of her outfit, particularly against the buttons. Her grimace then turned to joy as she adjusted said buttons to relieve some of the pressure about her middle, letting the bulge stick out more. With the momentary distraction ceased, Muffet returned to her gorging, “Mmmm...mmmm! So gooooood~” She thought, her eyes slightly closed as the fatigue from her feasting started to take its toll as her spindly frame wasn’t used to having so much food put into it all at once. Her engorged gut made sounds that could be confused for growling demons or bubbling cauldrons.

“Nnnngh…” Muffent groaned, arms and hands twitching as she sought out the last good on the table, in this case a croissant stuffed with strawberry and cream cheese. She pinched it around the middle, allowing some of the filling to leak out, before raising it up as if she were extracting a sword from its stone. She gasped, her own willpower surging forth as every muscle in her body screamed and begged not to add anything else into the utterly packed gut. The notion of her bakery closing from not being trusted as a baker and her pride in her art finally won over as she quickly stuffed it into her mouth. The taste, while still excellent, was the last detail on her mind as she slowly chewed and chewed, just trying her darndest to get the last bit down. Finally, with a big gulp, the croissant went down her throat and Muffet threw all six of her arms before she promptly collapsed onto her back, staring up at the ceiling.

“Baked goods: 0, Muffet: 1! I won the battle...I think?” She thought, the hard lump that was now her stomach making the victory seem like a pyrrhic one as her body struggled to digest the spread. She undid some of the buttons around where her stomach was, allowing the gray gut to spill forth as she rubbed her fingers all over it in a desperate bid to settle its gurgling. Surprisingly, her taxed tum responded positively to the touching (most likely from the tightness making her skin more sensitive) and made a gasp come from Muffet. It felt good.

“Wow...if I get to get this kind of comfort while I’m fattening myself up, I can’t wait to see how this whole thing goes.” She said to herself as she let some air out of her body and closed her eyes.

While she initially thought it was for only a moment, the sunset coming from outside her window suggested to Muffet anything but. The spider girl shot up and looked around. She must’ve passed out! A vexed sigh came from her as she slowly clambered up, finding it a bit more difficult than before as a hand instinctively went to rub her belly. Surprisingly, the firmness had given way to something a bit more…

“Soft?” Muffet thought as she looked down. Her exposed belly had gained a bit more curve to her and she could actively feel that it had gotten more pliable despite it still being a bit full from earlier. A great grin came up as she quickly moved into her living parlor just in the back room of the bakery. Using one of the strings to ensnare a bathroom scale, she pulled it over, kicked her boots off and stepped onto it as her smile grew even larger at seeing she’d in fact put on some pounds!

“Holy Arachne, I did it!” She cheered, looking down and feeling her sides. Her hips and posterior had gotten some of the love from the goods she’d eaten, making her pose in front of the mirror and strike a pose while pursuing her lips, “Hmmm...but I’ve got some work to do! The fattest lady in the circus didn’t get fat in a day after all!” She beamed before brainstorming her next approach.

"This must be the place." Devon Harrison said, the food critic looking up at the large sign depicting the silhouette image of a spider holding different baked goods in six of its arms and then a teapot and cup in the other two with the letters 'Muffet's Patisserie' set up above it. He looked back down at his small notebook before stepping inside. Shockingly, the entire place was actually rather busy with both humans and monsters of all kinds making idle small talk as they waited for the skittering spiders to take their orders.

"Welcome to Muffet's!" A peppy voice that exuded both fatigue and friendliness called out to him. Devon looked toward the front among the sea of people as his eyes locked on the proprietor of the bakery. A slight grimace of shock came over him from seeing her as the picture he’d seen from before was not at all representative of who Devon currently saw before him. In fact, she looked twice the size of the picture he’d seen, her spindly form instead a rotund one equipped with thick thighs and hips along with a dumptruck ass. A small pooch of a belly pushed out against her outfit even while her breasts had begun to droop down as they swelled. The gleaming smile on her face seemed to even be helped by her rounded face and thickening neck. Devon simply nodded back with a happy look of his own as he waited. Despite the large crowd, one of the spider workers promptly came up to him and asked for his order, to which he replied by asking for a small donut and coffee.

“Service is very efficient.” He noted as he eventually got the order he asked in a timely manner before going to sit down and eat what he’d acquired. Starting with a sip from the coffee cup, he nodded happily at the surprise he got. The taste made it seem like the coffee was homemade rather than simply being store bought grounds, certainly having been slow roasted to perfection. Further still, once he took a bite of the donut, he made an audible ‘mmmm’ at how delicious it was, firm without being too hard but also just soft enough that it wasn’t just like biting into a big ball of dough. The glaze had also been placed on and sprinkled to perfection without it simply feeling like a painted coating of pure sugar. Everything was absolutely balanced and it gave him a pleasant feeling as he finished it up and gently sipped his coffee while taking notes.

“Donut well made, coffee was a delightful little surprise, service is polite and wait time is nominal even at busiest hours.” He said, writing down on his notepad. As he wrote, though, he heard a sound from nearby that sounded like snapping followed by loud pinging and an impact. He whipped around to see the source of whatever had been hit, noticing a pair of skeletal monsters sitting nearby him with the taller one grabbing his head in pain.

“AIIEEEEE!” The taller of the two cried, “What...what was that? Who hit me?” He shouted, looking around the room.

“I think it was just a button, bro.” The smaller, blue hoodie-clad one said calmly with a little smile as he ate his eclair.

“Urrrgh...I don’t have a chip in my skull, do I?”

“No. You’ve got a hard enough head that it’s like armor.”

“HEY! I do not have that hard a head! It’s at a perfect level of hardness, I’ll have you know!” The taller skeleton shot back as the other one simply laughed. Devon, meanwhile, slowly turned his gaze over toward the front where Muffet was attempting to hide the fact that part of her belly was showing now through her outfit as she ducked behind the counter to hide herself while continuing to work and take orders while two of her employees helped her cover up the wardrobe conundrum that had occurred. He slowly nodded, impressed how much of a well-oiled machine that the entire bakery seemed to operate as.

“This might just be my first-ever five star review…”

"Oooooof…" Muffet groaned, rolling herself onto her back to stare at her ceiling with her eyes still halfway open from sleep. After a few minutes, she finally rolled herself onto her side and sat up as her bed made the same noise that she did when she initially awoke. The spider reached around and slipped her nightgown to try and cover her exposed belly only to grunt as it barely pulled all the way down, leaving a sliver of cobalt flab exposed. An annoyed grimace came from her as she struggled once more before eventually giving up altogether and just rising up as deep footfalls echoed throughout her bedroom while her flab jiggled about. Muffet made her way to her bathroom, two of her eyes still blinking and fluttering in-between being fully open and half-closed as her mind wandered around, still muddled by slumber. The obese arachanid grunted, her feet padding against the bare tile before she reached her scale and stepped into it. Unfortunately, she wasn't able to see what the numbers said as a combination of her overhanging gut, thick chest and triple chin prevented the hefty monster from being able to look down far enough. A third vexed expression that morning came across her face, this time with fangs exposed as she grit her canines and tried desperately to even catch a small peek at what her weight had climbed to. Her determination, however, wasn't enough to get past her physical limitations and she finally relented and sighed.

"Cassidy!" She called out. After a few short seconds, another spider emerged inside of the room and scuttled over to her, "Can you do me a favor and read the weight off to me? I can't see it."

"Of course, Muffet." The spider replied in a very regal tone as he moved to the front, "Hmm... it appears that the numbers have vanished. You may be required to do this once more." A grumble was Muffet's only response as she took a step back and then placed herself on once more.

"Okay, what does it say now?"

"E."

"E?" Muffet asked, cocking her head to the side, "That's...not a number, Cassidy."

"I would assume that your weight may be too high for this scale to read." The smaller spider added, “Shall I acquire the more industrial one you purchased recently?” At first Muffet appeared further irritated by having to get another piece of equipment just to figure out how much she actually weighed. This was quickly superseded by realizing that she’d gained so much that the most basic of scales she had was unable to read her prestigious girth and a smile crossed her face.

“YES! DO IT!” She said, making a little excited hop that predictably ended with a wrenching crunch as the small bathroom scale below her became less of a square and more of a pancake. She looked down at it and then over at Cassidy, “Erm...I’ll clean that up later.” She said, stepping off it and then kicking the debris over to the side. The spider nodded, walked off and then returned with the slightly thicker, sturdier and more expensive measurement device, “Thank you, Cassidy.” She smiled as she stepped on, “So, what does it say?” She asked, doing her best to stay still despite the anticipation.

“408.5 pounds, Muffet.”

"YES! YES YES YES!" Muffet cheered, "I'm officially huge compared to human standards!" She threw all of her flabby arms up in celebration as she made another small jump of joy...which then led to the scale getting smashed again, "...shoot, I did it again."

"You did. Though for a second you seemed to register as over 2000 pounds." Cassidy added in nonchalantly.

"Heh, I'll bet I did." Muffet put a hand up under her swollen face, "Hmmm...the bakery has been doing really really good recently. The humans really love my food, they trust my cooking because they trust a chef that's super fat." She then snapped a finger.

"Muffet?"

"Cassidy, that breakfast that I was going to eat today? Triple it!" She laughed, "I'm going to make myself into the biggest, fattest and most powerful chef in the whole world!" She grinned, small creases forming in the folds of her round visage.

***-15 Years Later

“Alright, five minutes until your cue, darlings!” Mettaton called out as Alphys nervously fidgeted in her chair.

“Alphy, relax.” Undyne the fish monster said as she kicked back in her own seat.

"Yeah, but it's not everyday that we have the biggest food businesswoman on the planet on our show, Undyne." The reptile replied as she pulled out a mirror and looked at it, "Do my spines look okay? Should I have worn my black dress instead of the cream one?”

“You would’ve looked good no matter what you wore, hon.” The red-headed, one-eyed aquatic girl waved her hand with a smile, crossing one of her legs over as she ran a hand down her own black colored suit, “Besides, it’s a good...contrast? That’s what you’d call it? Darks against lights?”

“Ahh! You remembered my color theory conversation!” Alphys immediately stopped her worrying and beamed, stars in her eyes as she looked over at her wife.

“Kinda’ hard not to. You get so amped about it all the time.” Undyne chuckled.

“30 seconds! Better get your game faces on!” Mettaton called out.

“Hey, that’s my line!.” She shot a glare at the automaton.

“Beat you to it, sweetheart!” Mettaton responded with a slight wink, making Undyne shake her head before she reached over and patted Alphys’ back.

“You got this, babe.”

“5...4...3…” The director said, counting down the last two numbers silently before the cameras all focused on the pair of monsters with a red light shining on one of them.

“G-greetings, everyone! Welcome to ‘Midday With Alphys and Undyne! Today, we have a pretty special guest” Alphys said, forcing a smile out.

“You know her, you’ve heard of her, you probably have eaten at one of the bakeries she owns-which is quite a few, gotta’ say-let me introduce all of you at home to...Muffet!” Undyne said, throwing her hand over to the left just off-stage. Silence came for a moment before a loud thump responded, making both hosts’ glasses of water on the table in front of them shake. This was followed by another loud boom that sounded a bit closer. Another, another...and then one more came as the thunderous footsteps finally culminated in a massive shape emerging. Undyne and Alphys both glanced over, both of their eyes going wide as Muffet slowly waddled her way into the camera’s view. She had grown absolutely massive, easily exceeding 1000 pounds as each step caused a quake of adipose to go off. Her gut fell in a massive apron almost to the floor with an equally impressive pair of breasts fully on top, displaying them like a pair of watermelons at a grocery store. The culinary giant (literally and figuratively) had traded out her trademark romper for a large, fancy business suit with a button-up long-sleeve shirt with a vest over the top, some striped bottoms that were filled out by her paunch, jiggly thighs and rear and wide hips, leggings that were about stretched to their limit by her lardy legs and high-heeled boots that seemed to barely lift anytime she took a hefty step forward.

After at least a minute of hefting her enormous frame (and knocking over anything light that wasn’t nailed down) Muffet finally came to rest on the large, reinforced chair that was set up opposite to Alphys and Undyne.

“Whew...you two ever consider getting a conveyor belt for your guests?” She asked, a chuckle coming from her enormous, cherubic face.

“I think after that long of a beat, we’re gonna’ consider it.” Undyne smiled and nodded, “So, Muffet, let’s get down to the interview: It’s been really incredible the meteoric rise you had in the past decade. What do you think you’d pin that success on?”

"This!" Muffet grabbed her belly with her arms and then let it drop, the blubbery dome bouncing like a massive bag filled with jelly, "It shows I'm the biggest and the best pastry chef out there!” The statement left both of the hosts totally stunned as they glanced over at one another.

“You...attribute your success to your current size?” Alphys asked, "Umm…"

"Well, being a strong and smart businesswoman probably helps too!" Muffet beamed, "I've completely taken over other places and added them into my empire! Heck, my original location is named Muffet's Powerful Patisserie now." She laughed.

"The acquisition of a certain large donut chain did make worldwide news, yes." The lizard slowly nodded as she listened, still attempting to process what exactly she was hearing.

“I think that’s pretty rad! What’s that saying that everyone talks about again?” Undyne put her hand to her chin.

“‘Never Trust a Skinny Chef!’” Muffet piped in, moving her head around as her ponytail rested on her pillow shoulder.

“That’s the one!” The aquatic red-head clapped, “Gotta’ say for sure that when it comes to pastries, you’re certainly trustworthy.” She laughed.

“Truthfully, I’ve had to keep myself from indulging in them. I’m already round enough as it is.” Alphys broke a small smile.

“I’m actually thinking I could get even rounder.” Muffet cackled, “I just don’t know if my home could support it, though, especially since I’m going to be having someone move in soon.”

“Oh?” The reptile and fish asked in unison, leaning in closer.

“Thought I’d reel you in with that little bit of gossip, huh?” Muffet twirled a few fingers at the pair with a cheeky grin, “Yes, I’m announcing it here now that I’ve been seeing someone over the past several months and we are so very much in love and they’ve been totally instrumental in helping me finalize things with a completely brand new business deal that will see me named as the number one provider of baked goods in the entire country!” She then raised both her arms up as the crowd in the studio gave a cheer.

“That’s intriguing. Is it anyone we know?” Alphys asked.

“You could say that.” Muffet looked behind her as a tall, slender figure emerged from the backgroom. Brown hair cascaded down their back as they walked out wearing a fancy coat with some black dress pants and some boots.

And also a telltale blue and a purple-striped shirt that the hosts of the show immediately recognized.

“FRISK?!” They both once again cried out.

“Hey, guys.” The human waved happily to them as they walked over next to Muffet, smiling and taking one of the spider’s hands in their own.

“Oh my, what a development.” Mettaton whispered to the rest of the surprised crew.

“My dear has been wonderful with using their knowledge of all kinds of negotiation tactics from their time as a diplomat to help me with getting business deals, settling disputes and all sorts of things.” Muffet smiled, “Plus, they’re also an absolutely lovely individual on top of that.” She smiled as Frisk leaned up to plant a kiss on the baker’s fat cheek.

“And you give the best hugs, sweety.” Frisk added, a bright smile on their face.

“That’s so wonderful!” Alphys squeed, “I had no idea that the two of you were even together! This is outstanding!”

“Our little Frisk is finally grown up.” Undyne said, sniffing.

“Hey, come on. You’re gonna’ make me blush.” Frisk rolled their eyes and waved away the statement.

“Wow, I’m quite surprised the two of you managed to keep this out of the public eye for as long as you did. Good on you for being discreet.” Alphys added.

“I know I certainly wouldn’t have been!” Mettaton called out, “Also, hi, Frisky!”

“Heya’, Mettaton.” Frisk waved off-camera to the robot.

“Heh, guess this ended up being an even more exciting show than we had expected to actually film out. Thanks for coming onto the show and using us to announce you two being together!” Undyne beamed.

“Happy to be here.” Frisk smiled.

“Thanks for having us!” Muffet added in, “It was a pleasure to be here.” She said before looking over, “Love, would you mind helping me up?”

“Of course, Muffet.” They replied as Frisk stood up and put their arms under Muffet’s massive frame to help them rise up.

“See you again at some point and good day to everyone here!” Muffet waved to the rest of the audience as she trudged and stomped her way off the set, leaving Alphys and Undyne sitting at their respective seats.

“Wow. There goes one strong couple.” Alphys smiled proudly.

“Yeah.” Undyne chuckled, “We’re still gonna’ be the number one power couple five years running, though.” She said, pumping a fist in the air and grinning.

“Oh...um...actually, Undyne, sweety, the new rankings for that came in. You and Alphy-kins are at second place now.” Mettaton said, wincing slightly as he delivered the news.

“...WHAT.”

Description
CW: Weight gain, stuffing.

Muffet the spider decides that in order to help her bakery succeed, she'll need to make some BIG changes. Get it? Big changes? Because she gets fat?

Commission for and this was an absolute joy to work on. The idea was hilarious and fit with Undertale's tone perfectly and I think Muffet doesn't get nearly enough fat focused stuff on her. ^^ Enjoy!

===

“Oh come on...there’s no way they were that bad!” Muffet the spider groaned as she watched a human rush out of her bakery having taken a single bite from one of her cupcakes, the man at least five seconds away from gagging on it as he dropped it and fled, “Fine! You’re not allowed in here again!” She snarled, “Ungrateful...urrrrgh…” A sigh came from the arachne as she walked over to pick up the treat, shrugging and popping it into her mouth, “Five second rule.” She said to herself before walking back over to the counter, setting her head down on it as all five of her eyes looked around at the empty bakery and letting out another deep sigh of frustration and annoyance, but mostly annoyance.

"Why don't these humans appreciate my baked goods?" Muffet thought as she looked over at one of the donuts sitting in the glass display case, reaching one of her arms in to snatch it and take a bite.

"I had monsters beating on my web lines to get my treats in the Underground. What am I doing wrong up here? Did I lose my touch somehow?" She asked herself. It had been almost a year since the barrier separating the Human World and the Underground had come down with many monsters choosing to leave and explore their suddenly new surroundings. Muffet had been one of them and chosen to continue with the craft that she knew best, but was now obviously finding some difficulty, "Hmmm...perhaps a fourth pair of eyes might be good to have in this situation." She said, opening up a small book underneath her counter and flipping through the pages.

***

"Huh...I was expecting something a bit more extravagant." Muffet commented on the somewhat quaint looking house present before out in the suburbs. The only thing fully indicating the presence of who she was there to see was that of a purple Delta rune based knocker on the front of the door. She slowly nodded and psyched herself up before reaching an arm up to use it. A short time passed before the door clicked and opened up as a tall, white-furred goat-like being looked down before a smile crossed her face.

"Why hello there." Toriel said, "How are you doing today?"

"Hello, Miss Toriel." Muffet said, slightly nervous at seeing the motherly monster in the flesh, "I'm, um, Muffet." She said, "I'm actually a bit of a fan of yours and I wanted to come by and-" She abruptly cut herself off and facepalmed, "Shoot, I just came off like a complete creeper by saying that, didn't I?" Her embarrassment suddenly molded into confusion when the Boss Monster giggled and she looked back up.

"It's alright, my child." Toriel smiled and stepped to the side, "Please, come in and we'll discuss what you wish." She nodded before walking inside, the spider following her in, "Can I get you some tea?”

“Yes, that would be nice.” Muffet looked around the whole household as she walked about. It was very welcoming with warm colors and soft furniture, matching the personality that she’d been greeted with at the door.

“Feel free to take a seat if you want.” Toriel smiled as she walked back into a nearby kitchen. Muffet did so, the cushiony chair feeling comfortable as she waited for a few minutes. Toriel returned shortly after with two cups of tea and a small plate on a platter that contained a pair of small cakes.

“Thank you.” Muffet nodded as Toriel handed her one of the cups, “Mmmm...that smells good. Is that some snail tea?”

“I figured you might like it.” Toriel beamed as she sat down as well, “So, what can I do for you?”

“Well, I opened up a bakery about a month ago and business has been...not great.” She said, the slim digits of her fingers running along the handle, “Some of the monsters that I had come to my bake sale in the Underground come by but I haven’t had a single human stick around to try out anything else. They just kinda’ cut and run after seeing me.” She took a sip from the cup, “But everything tastes fine when I eat it and monsters still like them. What do you think I’m doing wrong?” She asked.

“Hmmm…” Toriel sat back in her chair, still holding the teacup in her paws as she looked to be in deep thought, “Well, I must say that I’m not exactly what you would call an expert in business. I’ve never really considered selling any of the things I bake. The only thing that I could see you potentially refining would be advertising. But you also say that humans run from your bakery?”

“Yeah.” Muffet nodded as she drank from her tea and took a bite from the small cake, “I heard that a lot of humans are afraid of spiders. Do they think I’m going to eat them or something?”

“As much as it pains me to say, that could be a possibility.” Toriel sighed, “Frisk is doing as much as possible as an ambassador between humans and monsters but they can only do so much. It has only been a year after all.”

“Well, I don’t think that I have that long. I need some solutions now.” She took another bite from the cake, “Maybe I could try hiring that angry yelling man I see on TV, the one with wrinkles on his forehead? Maybe he could really-” She abruptly cut herself off, “-this cake is so delicious! Sorry, I just had to compliment.” The romper-clad spider smiled.

“Why thank you.” Toriel nodded, “It’s a favorite of mine and most of the monsters and humans that come see me.”

“I can see why. The flavor in this is incredible.” She went, finishing up the cake, “Mmmm…” She went, bringing her hand up to lick some of the crumbs and excess frosting off. While she did, her eyes flitted subconsciously about the room. She found herself focusing on a sign hanging just in the entrance of Toriel’s kitchen with a white chef’s hat with some stylized text reading ‘Never Trust A Skinny Chef.’ She looked the decorative placard up and down before she got up and walked closer up to it, “What does this mean?” She asked, pointing up at it.

“Oh?” Toriel asked, setting the tea down and picking up her reading glasses, “Oh, that.” She smiled, “Asgore got that for me after I moved in here. It’s apparently a fun human saying.” She let out a slight giggle, “And he did always have an appreciation for my curves.” She said, a light blush coming over her white muzzle.

“Never trust a skinny chef…” Muffet repeated, all of her eyes locked on the sign as she processed what Toriel had told her. A large, toothy grin came across her face as she got an idea in her head before she flipped around to run over and give Toriel a big hug, "Thank you so much, Miss Toriel! You are the goat! The G.O.A.T., that is!" She cheered, "Sorry, I have a lot of preparation to do, come see me the next time you get a chance!" She clapped her hands together and then quickly took off out of the house, stopping only to politely close the door behind her.

"Oh my...what just happened?" The dazed Boss Monstress asked herself.

***

A day later, Muffet put her hands on her hips as she looked at the impressive spread of sweets in front of her while she rubbed two of her upper hands together.

“Mmmm...I have to hand it to these human bakers. These pastries smell absolutely delish.” She grinned, “And every single one of them are mine~” She went with a sing-songy tone as she walked up to them, “Hmmm…” Two of her hands darted around as she seemed to have trouble deciding just which one to actually start eating. She eventually just shrugged and snatched an eclair and a chocolate cornette and stuffed them into her mouth one after the other. The moment that each one went into her mouth and collided with her taste buds, her eyes blinked rapidly as she savored the flavor. Despite having lived above ground for a decent amount of time, Muffet had never actually sampled anything from the bakeries and was now kicking herself for not doing so as the flaky crust of the cornette and not-too-sweet icing of the eclair made her totally giddy and wanting to have even more. Six hands shot forward and moved across several dishes as fritters, donuts, muffins, and cupcakes of all kinds were snatched up and put into her toothy maw, the sugary confections causing a chain reaction as her neurons fired off with total delight.

"~Tasty tasty treats for me, all of them in my belly~" Muffet thought as she kept up her feast, unaware that she'd eaten almost half the spread. As the wiry-built baker went to drop another donut into her drooling mouth, she stopped momentarily as she felt a sudden sharp pinch come from her middle. Looking down with an annoyed stare, she found that her normally slim belly had become distended and had started to push up against the fabric of her outfit, particularly against the buttons. Her grimace then turned to joy as she adjusted said buttons to relieve some of the pressure about her middle, letting the bulge stick out more. With the momentary distraction ceased, Muffet returned to her gorging, “Mmmm...mmmm! So gooooood~” She thought, her eyes slightly closed as the fatigue from her feasting started to take its toll as her spindly frame wasn’t used to having so much food put into it all at once. Her engorged gut made sounds that could be confused for growling demons or bubbling cauldrons.

“Nnnngh…” Muffent groaned, arms and hands twitching as she sought out the last good on the table, in this case a croissant stuffed with strawberry and cream cheese. She pinched it around the middle, allowing some of the filling to leak out, before raising it up as if she were extracting a sword from its stone. She gasped, her own willpower surging forth as every muscle in her body screamed and begged not to add anything else into the utterly packed gut. The notion of her bakery closing from not being trusted as a baker and her pride in her art finally won over as she quickly stuffed it into her mouth. The taste, while still excellent, was the last detail on her mind as she slowly chewed and chewed, just trying her darndest to get the last bit down. Finally, with a big gulp, the croissant went down her throat and Muffet threw all six of her arms before she promptly collapsed onto her back, staring up at the ceiling.

“Baked goods: 0, Muffet: 1! I won the battle...I think?” She thought, the hard lump that was now her stomach making the victory seem like a pyrrhic one as her body struggled to digest the spread. She undid some of the buttons around where her stomach was, allowing the gray gut to spill forth as she rubbed her fingers all over it in a desperate bid to settle its gurgling. Surprisingly, her taxed tum responded positively to the touching (most likely from the tightness making her skin more sensitive) and made a gasp come from Muffet. It felt good.

“Wow...if I get to get this kind of comfort while I’m fattening myself up, I can’t wait to see how this whole thing goes.” She said to herself as she let some air out of her body and closed her eyes.

While she initially thought it was for only a moment, the sunset coming from outside her window suggested to Muffet anything but. The spider girl shot up and looked around. She must’ve passed out! A vexed sigh came from her as she slowly clambered up, finding it a bit more difficult than before as a hand instinctively went to rub her belly. Surprisingly, the firmness had given way to something a bit more…

“Soft?” Muffet thought as she looked down. Her exposed belly had gained a bit more curve to her and she could actively feel that it had gotten more pliable despite it still being a bit full from earlier. A great grin came up as she quickly moved into her living parlor just in the back room of the bakery. Using one of the strings to ensnare a bathroom scale, she pulled it over, kicked her boots off and stepped onto it as her smile grew even larger at seeing she’d in fact put on some pounds!

“Holy Arachne, I did it!” She cheered, looking down and feeling her sides. Her hips and posterior had gotten some of the love from the goods she’d eaten, making her pose in front of the mirror and strike a pose while pursuing her lips, “Hmmm...but I’ve got some work to do! The fattest lady in the circus didn’t get fat in a day after all!” She beamed before brainstorming her next approach.

"This must be the place." Devon Harrison said, the food critic looking up at the large sign depicting the silhouette image of a spider holding different baked goods in six of its arms and then a teapot and cup in the other two with the letters 'Muffet's Patisserie' set up above it. He looked back down at his small notebook before stepping inside. Shockingly, the entire place was actually rather busy with both humans and monsters of all kinds making idle small talk as they waited for the skittering spiders to take their orders.

"Welcome to Muffet's!" A peppy voice that exuded both fatigue and friendliness called out to him. Devon looked toward the front among the sea of people as his eyes locked on the proprietor of the bakery. A slight grimace of shock came over him from seeing her as the picture he’d seen from before was not at all representative of who Devon currently saw before him. In fact, she looked twice the size of the picture he’d seen, her spindly form instead a rotund one equipped with thick thighs and hips along with a dumptruck ass. A small pooch of a belly pushed out against her outfit even while her breasts had begun to droop down as they swelled. The gleaming smile on her face seemed to even be helped by her rounded face and thickening neck. Devon simply nodded back with a happy look of his own as he waited. Despite the large crowd, one of the spider workers promptly came up to him and asked for his order, to which he replied by asking for a small donut and coffee.

“Service is very efficient.” He noted as he eventually got the order he asked in a timely manner before going to sit down and eat what he’d acquired. Starting with a sip from the coffee cup, he nodded happily at the surprise he got. The taste made it seem like the coffee was homemade rather than simply being store bought grounds, certainly having been slow roasted to perfection. Further still, once he took a bite of the donut, he made an audible ‘mmmm’ at how delicious it was, firm without being too hard but also just soft enough that it wasn’t just like biting into a big ball of dough. The glaze had also been placed on and sprinkled to perfection without it simply feeling like a painted coating of pure sugar. Everything was absolutely balanced and it gave him a pleasant feeling as he finished it up and gently sipped his coffee while taking notes.

“Donut well made, coffee was a delightful little surprise, service is polite and wait time is nominal even at busiest hours.” He said, writing down on his notepad. As he wrote, though, he heard a sound from nearby that sounded like snapping followed by loud pinging and an impact. He whipped around to see the source of whatever had been hit, noticing a pair of skeletal monsters sitting nearby him with the taller one grabbing his head in pain.

“AIIEEEEE!” The taller of the two cried, “What...what was that? Who hit me?” He shouted, looking around the room.

“I think it was just a button, bro.” The smaller, blue hoodie-clad one said calmly with a little smile as he ate his eclair.

“Urrrgh...I don’t have a chip in my skull, do I?”

“No. You’ve got a hard enough head that it’s like armor.”

“HEY! I do not have that hard a head! It’s at a perfect level of hardness, I’ll have you know!” The taller skeleton shot back as the other one simply laughed. Devon, meanwhile, slowly turned his gaze over toward the front where Muffet was attempting to hide the fact that part of her belly was showing now through her outfit as she ducked behind the counter to hide herself while continuing to work and take orders while two of her employees helped her cover up the wardrobe conundrum that had occurred. He slowly nodded, impressed how much of a well-oiled machine that the entire bakery seemed to operate as.

“This might just be my first-ever five star review…”

"Oooooof…" Muffet groaned, rolling herself onto her back to stare at her ceiling with her eyes still halfway open from sleep. After a few minutes, she finally rolled herself onto her side and sat up as her bed made the same noise that she did when she initially awoke. The spider reached around and slipped her nightgown to try and cover her exposed belly only to grunt as it barely pulled all the way down, leaving a sliver of cobalt flab exposed. An annoyed grimace came from her as she struggled once more before eventually giving up altogether and just rising up as deep footfalls echoed throughout her bedroom while her flab jiggled about. Muffet made her way to her bathroom, two of her eyes still blinking and fluttering in-between being fully open and half-closed as her mind wandered around, still muddled by slumber. The obese arachanid grunted, her feet padding against the bare tile before she reached her scale and stepped into it. Unfortunately, she wasn't able to see what the numbers said as a combination of her overhanging gut, thick chest and triple chin prevented the hefty monster from being able to look down far enough. A third vexed expression that morning came across her face, this time with fangs exposed as she grit her canines and tried desperately to even catch a small peek at what her weight had climbed to. Her determination, however, wasn't enough to get past her physical limitations and she finally relented and sighed.

"Cassidy!" She called out. After a few short seconds, another spider emerged inside of the room and scuttled over to her, "Can you do me a favor and read the weight off to me? I can't see it."

"Of course, Muffet." The spider replied in a very regal tone as he moved to the front, "Hmm... it appears that the numbers have vanished. You may be required to do this once more." A grumble was Muffet's only response as she took a step back and then placed herself on once more.

"Okay, what does it say now?"

"E."

"E?" Muffet asked, cocking her head to the side, "That's...not a number, Cassidy."

"I would assume that your weight may be too high for this scale to read." The smaller spider added, “Shall I acquire the more industrial one you purchased recently?” At first Muffet appeared further irritated by having to get another piece of equipment just to figure out how much she actually weighed. This was quickly superseded by realizing that she’d gained so much that the most basic of scales she had was unable to read her prestigious girth and a smile crossed her face.

“YES! DO IT!” She said, making a little excited hop that predictably ended with a wrenching crunch as the small bathroom scale below her became less of a square and more of a pancake. She looked down at it and then over at Cassidy, “Erm...I’ll clean that up later.” She said, stepping off it and then kicking the debris over to the side. The spider nodded, walked off and then returned with the slightly thicker, sturdier and more expensive measurement device, “Thank you, Cassidy.” She smiled as she stepped on, “So, what does it say?” She asked, doing her best to stay still despite the anticipation.

“408.5 pounds, Muffet.”

"YES! YES YES YES!" Muffet cheered, "I'm officially huge compared to human standards!" She threw all of her flabby arms up in celebration as she made another small jump of joy...which then led to the scale getting smashed again, "...shoot, I did it again."

"You did. Though for a second you seemed to register as over 2000 pounds." Cassidy added in nonchalantly.

"Heh, I'll bet I did." Muffet put a hand up under her swollen face, "Hmmm...the bakery has been doing really really good recently. The humans really love my food, they trust my cooking because they trust a chef that's super fat." She then snapped a finger.

"Muffet?"

"Cassidy, that breakfast that I was going to eat today? Triple it!" She laughed, "I'm going to make myself into the biggest, fattest and most powerful chef in the whole world!" She grinned, small creases forming in the folds of her round visage.

***-15 Years Later

“Alright, five minutes until your cue, darlings!” Mettaton called out as Alphys nervously fidgeted in her chair.

“Alphy, relax.” Undyne the fish monster said as she kicked back in her own seat.

"Yeah, but it's not everyday that we have the biggest food businesswoman on the planet on our show, Undyne." The reptile replied as she pulled out a mirror and looked at it, "Do my spines look okay? Should I have worn my black dress instead of the cream one?”

“You would’ve looked good no matter what you wore, hon.” The red-headed, one-eyed aquatic girl waved her hand with a smile, crossing one of her legs over as she ran a hand down her own black colored suit, “Besides, it’s a good...contrast? That’s what you’d call it? Darks against lights?”

“Ahh! You remembered my color theory conversation!” Alphys immediately stopped her worrying and beamed, stars in her eyes as she looked over at her wife.

“Kinda’ hard not to. You get so amped about it all the time.” Undyne chuckled.

“30 seconds! Better get your game faces on!” Mettaton called out.

“Hey, that’s my line!.” She shot a glare at the automaton.

“Beat you to it, sweetheart!” Mettaton responded with a slight wink, making Undyne shake her head before she reached over and patted Alphys’ back.

“You got this, babe.”

“5...4...3…” The director said, counting down the last two numbers silently before the cameras all focused on the pair of monsters with a red light shining on one of them.

“G-greetings, everyone! Welcome to ‘Midday With Alphys and Undyne! Today, we have a pretty special guest” Alphys said, forcing a smile out.

“You know her, you’ve heard of her, you probably have eaten at one of the bakeries she owns-which is quite a few, gotta’ say-let me introduce all of you at home to...Muffet!” Undyne said, throwing her hand over to the left just off-stage. Silence came for a moment before a loud thump responded, making both hosts’ glasses of water on the table in front of them shake. This was followed by another loud boom that sounded a bit closer. Another, another...and then one more came as the thunderous footsteps finally culminated in a massive shape emerging. Undyne and Alphys both glanced over, both of their eyes going wide as Muffet slowly waddled her way into the camera’s view. She had grown absolutely massive, easily exceeding 1000 pounds as each step caused a quake of adipose to go off. Her gut fell in a massive apron almost to the floor with an equally impressive pair of breasts fully on top, displaying them like a pair of watermelons at a grocery store. The culinary giant (literally and figuratively) had traded out her trademark romper for a large, fancy business suit with a button-up long-sleeve shirt with a vest over the top, some striped bottoms that were filled out by her paunch, jiggly thighs and rear and wide hips, leggings that were about stretched to their limit by her lardy legs and high-heeled boots that seemed to barely lift anytime she took a hefty step forward.

After at least a minute of hefting her enormous frame (and knocking over anything light that wasn’t nailed down) Muffet finally came to rest on the large, reinforced chair that was set up opposite to Alphys and Undyne.

“Whew...you two ever consider getting a conveyor belt for your guests?” She asked, a chuckle coming from her enormous, cherubic face.

“I think after that long of a beat, we’re gonna’ consider it.” Undyne smiled and nodded, “So, Muffet, let’s get down to the interview: It’s been really incredible the meteoric rise you had in the past decade. What do you think you’d pin that success on?”

"This!" Muffet grabbed her belly with her arms and then let it drop, the blubbery dome bouncing like a massive bag filled with jelly, "It shows I'm the biggest and the best pastry chef out there!” The statement left both of the hosts totally stunned as they glanced over at one another.

“You...attribute your success to your current size?” Alphys asked, "Umm…"

"Well, being a strong and smart businesswoman probably helps too!" Muffet beamed, "I've completely taken over other places and added them into my empire! Heck, my original location is named Muffet's Powerful Patisserie now." She laughed.

"The acquisition of a certain large donut chain did make worldwide news, yes." The lizard slowly nodded as she listened, still attempting to process what exactly she was hearing.

“I think that’s pretty rad! What’s that saying that everyone talks about again?” Undyne put her hand to her chin.

“‘Never Trust a Skinny Chef!’” Muffet piped in, moving her head around as her ponytail rested on her pillow shoulder.

“That’s the one!” The aquatic red-head clapped, “Gotta’ say for sure that when it comes to pastries, you’re certainly trustworthy.” She laughed.

“Truthfully, I’ve had to keep myself from indulging in them. I’m already round enough as it is.” Alphys broke a small smile.

“I’m actually thinking I could get even rounder.” Muffet cackled, “I just don’t know if my home could support it, though, especially since I’m going to be having someone move in soon.”

“Oh?” The reptile and fish asked in unison, leaning in closer.

“Thought I’d reel you in with that little bit of gossip, huh?” Muffet twirled a few fingers at the pair with a cheeky grin, “Yes, I’m announcing it here now that I’ve been seeing someone over the past several months and we are so very much in love and they’ve been totally instrumental in helping me finalize things with a completely brand new business deal that will see me named as the number one provider of baked goods in the entire country!” She then raised both her arms up as the crowd in the studio gave a cheer.

“That’s intriguing. Is it anyone we know?” Alphys asked.

“You could say that.” Muffet looked behind her as a tall, slender figure emerged from the backgroom. Brown hair cascaded down their back as they walked out wearing a fancy coat with some black dress pants and some boots.

And also a telltale blue and a purple-striped shirt that the hosts of the show immediately recognized.

“FRISK?!” They both once again cried out.

“Hey, guys.” The human waved happily to them as they walked over next to Muffet, smiling and taking one of the spider’s hands in their own.

“Oh my, what a development.” Mettaton whispered to the rest of the surprised crew.

“My dear has been wonderful with using their knowledge of all kinds of negotiation tactics from their time as a diplomat to help me with getting business deals, settling disputes and all sorts of things.” Muffet smiled, “Plus, they’re also an absolutely lovely individual on top of that.” She smiled as Frisk leaned up to plant a kiss on the baker’s fat cheek.

“And you give the best hugs, sweety.” Frisk added, a bright smile on their face.

“That’s so wonderful!” Alphys squeed, “I had no idea that the two of you were even together! This is outstanding!”

“Our little Frisk is finally grown up.” Undyne said, sniffing.

“Hey, come on. You’re gonna’ make me blush.” Frisk rolled their eyes and waved away the statement.

“Wow, I’m quite surprised the two of you managed to keep this out of the public eye for as long as you did. Good on you for being discreet.” Alphys added.

“I know I certainly wouldn’t have been!” Mettaton called out, “Also, hi, Frisky!”

“Heya’, Mettaton.” Frisk waved off-camera to the robot.

“Heh, guess this ended up being an even more exciting show than we had expected to actually film out. Thanks for coming onto the show and using us to announce you two being together!” Undyne beamed.

“Happy to be here.” Frisk smiled.

“Thanks for having us!” Muffet added in, “It was a pleasure to be here.” She said before looking over, “Love, would you mind helping me up?”

“Of course, Muffet.” They replied as Frisk stood up and put their arms under Muffet’s massive frame to help them rise up.

“See you again at some point and good day to everyone here!” Muffet waved to the rest of the audience as she trudged and stomped her way off the set, leaving Alphys and Undyne sitting at their respective seats.

“Wow. There goes one strong couple.” Alphys smiled proudly.

“Yeah.” Undyne chuckled, “We’re still gonna’ be the number one power couple five years running, though.” She said, pumping a fist in the air and grinning.

“Oh...um...actually, Undyne, sweety, the new rankings for that came in. You and Alphy-kins are at second place now.” Mettaton said, wincing slightly as he delivered the news.

“...WHAT.”
