Undertale: The Regression Spell

[MyNinjaAcademia]

Swap found herself blushing lightly as Napstabot’s weight on her lap drew attention to the thick padding she wore underneath, having forgotten it was there until a soft rustle reminded her of it.

She waited by patiently as she listened to Frisk list off her favorite games, nodding along, glancing over towards Chara as she entered into the room, waiting for her answer.

She kept her arms wrapped around Napstabot, gently bouncing him up and down on her lap agin and again, finding herself giggling softly as she let him cuddle up to her, gently squeezing the baby in her arms, finding herself cooing down at him, trying to keep him entertained.

Just holding him was soothing her worries and fears. If she was still so good with babies, there was no way she could EVER be turning into one herself… that’s how it works, right?

“Good boy…” Swap praised him softly, reaching a hand up and playfully pinching one of his cheeks, before moving down and tickling his tummy, smiling as she listened to his adorable babbling as he attempted to call out to Sans and Asriel, not really understanding what he was saying, but still nodding along, pretending as if she did, letting out small “mhm”s and “uh-huh!”s.

“You’re such a cutie.” She cooed, grunting softly as she placed her arms under his armpits, slowly lifting the android up so he could get a better look at the games in front of them. “Which one do you wanna play first, little guy?” She asked, tilting her head to the side as she gave him a small, kind smile.

==================================

Not very long after Toriel had sent the email, practically almost instantly… there was a reply. It was long, frantic… and clearly very desperate and worried, yet somehow still remaining formal and polite. It asked… many, many questions. “Is she okay? Was it the regression spell? Is there a way to reverse it? Is it permanent? Will there be side effects? Has she shown any signs?” Were all apart of it, clearly very worried about Swap’s wellbeing.

"I wike candyland." Chara said as she joined her sister. It was, as she felt, a more mature feeling game than chutes and ladders to her and she was hoping to keep showing she can be mature so she wanted a more mature game. Her logic was...unsure but it's what she thought would be best.

-------------------------------------------------------

Asriel cooed gently as Sans waved Toriel and Asgore bye before joining the kids for the board game. "Alrighty kiddos what did ya pick out?" Sans asked as he leaned over to see each of the kids.

[Strawberry Surprise]

((Hey there, I finally got past my writers' block and stuff to get a reply done. Thanks for your patience, guys. <3 Refresher: Swap’s wearing a Disney Princess Pull-Up. They are not that thick, from what I recall. Not sure if you forgot?))

The message Toriel received in her emails would have to be read when she got home from the date, as she was giving all attention to her husband at the time and wouldn’t notice till then. Once she saw it however, the goat mom would be sure to give as detailed a reply as she could, to answer all the questions.

=====================================

Napsta was glad to hear the games Frisk liked. She had named some easier ones that would make it possible for babies like him and Asriel to join in. He watched Chara come into the room, his gaze flicking briefly to her before gliding away. He was scared to meet her gaze, not knowing what kind of reaction she might have towards him staring.

As he was lightly bounced, he gave a toothless grin and intermittent soft giggles, enjoying the way Swap played with him. His mood was playful and cheerful due to the bouncing and he felt almost giddy with sugary glee. It sounded like Swap was enjoying this too, her soft giggles drifting from slightly above and behind him. She was super nice. He felt happy and safe in her hands. When she gave him a loving squeeze, the baby boy gave a small squeak of happiness, closing his eyes for a moment. This is what it felt like to be loved and adored. He savoured the feeling, listening to her pleasant coos.

Being called a good boy made him grin and gurgle with delight, cheeks turning light blue as the shy boy blushed upon receiving such words from the other world princess. He would try to be as good as possible for Swap. He’d do anything for her. He just wanted to keep making her happy and receive more of her praise.

When his cheek was pinched by her warm fingers, he winced slightly, closing one eye but then giggled, finding it silly. His cheeks were so chubby in this form! So that’s what that felt like. At least her pinch was gentle and playful. Laughter tumbled out of him as she tickled his tummy, making the boy kick and squirm slightly on her lap. “Ahehehe! Ahehe!”

Swap listened to his attempts at speaking and he flushed blue again as she made noises of acknowledgement, pretending to understand what he was trying to say. Or maybe she did. He wasn’t sure. But he appreciated her efforts. It made him feel heard and appreciated. The princess was really so sweet. Napstabot really liked her. He trusted her a lot already.

“A-aa!” Napstabot’s blush brightened when she called him such a cutie. Really? She thought he was cute?! He always got flustered when other people said it and now was no exception but the fact that it was coming from her made him happy. He gasped and clung suddenly when she lifted him up in the air but felt safe that she wouldn’t drop him. Still, it was a little scary. Hearing her question, he swallowed his fear and focused his gaze down on the game boxes before moving one arm to point at the Candyland one. He liked the bright colours and heard it was easy to play. “Ga-ahh!”

That one. Plus, hearing Chara’s choice only reassured him he’d chosen correctly, since he wouldn’t want to go against her. It looked like things were coming together nicely.

======================================

Frisk listened to her sister and smiled at her choice, smiling brighter when she saw Napstabot point at the same box, bringing them into agreement. She changed her sitting position to a more comfortable and polite one, sitting with her knees together neatly and her skirt covering her thighs. Well, as close together as she could get them, not able to close her legs fully with the damp padding between them.

“Ohhh…Napsta likes it, too. Okay den, we’ll play Candyland fiwst,” she decided.

“Awe chu otay wiff dat, Swap? It’s weally easy. We just take tuwns picking a cawd and mobing ouw pieces to the matching colow on da boawd. If chu get a liquorice space, it means chu lose a tuwn. Dewe’s also showtcuts dat helps you mobe fow-wawds. And da fiwsd one to make it to the Candy Castle wins”.

Frisk briefly explained the easy rules of the game. “Oh, and chu can mobe Napsta’s piece fow him, ifs you want”.

She saw Sans come into the family room and turned to look at him with a fond smile, the blush that had been calming down brightening once more as her good friend saw her in her current state. She subconsciously grabbed at her skirt, pulling it down.

“S-Sans! Hi! Um…we’we playing Candyland fiwsd. Chawa likes it and so does Napsta. Plus, it’s super easy and fun. Um…uh…I pwomised him and Azzy that we’d help dem join in. So, do you wanna mobe Azzy’s pawn piece when it’s his tuwn? And do you need me to tell you da wules?”

She watched her fluffy, adorable brother in Sans’ arms, smiling and waving at him “Hi Azzy, do you wanna play wiff us? We’we playin’ boawd games. Chu can join in too".

[MyNinjaAcademia]

Swap was giggling at all of Napstabot’s cute responses to her praise and cuddling with him. His little giggles made her heart flutter, squealing with joy, gently swaying back and forth with him in her grasp. He was too cute for words. She smiled warmly at him as she watched him point down at the Candyland box, nodding and slowly lowering him back down into her lap, once again wrapping her arms protectively around him. “That one?” She grinned.

She perked up, turning her attention to Frisk, giving a soft nod to show that she was listening intently to the rules being explained. “Oh… sure! Yeah, seems simple enough.” She agreed, before turning back down to the baby in her lap. “Do you want me to?” She asked him softly, referring to Frisk’s question, asking if it was okay for her to move his piece for him.

She turned to look up at Sans as he entered into the room, her eyes wandering down to the fluffy, tiny goat in his arms, unable to stop herself from smiling warmly at the sight, cooing softly. He really did remind her of her own brother back home… just a lot smaller.

[Temmiedasithlowd]

"Alright so the rules of this game are pretty simple, you take a card and depending on what's on it you move that many spaces of that color with your piece, there's also special ones that take you to special spaces, the ones with marked candy, then you can instantly move to that space, but these cards could also send you back so be careful." Sans swiftly and simply explained the rules, being sure it was on a level the older kids would at least understand.

======================================

"Dat makes senses." Chara nodded as she chose a piece and set it on the start space, watching as each of the kids and babies picked a piece. the babies, of course, didn't get to hold theirs very long, to avoid the risk of them trying to eat the pieces.

======================================

Asriel smiled and happily grabbed the green piece before Sans gently plucked it from his hands and set it on the start and despite the goat baby's initial protest he was quickly given a pacifier to stave him over as he cooed and contently suckled on it.

[Strawberry Surprise]

Frisk smiled when Swap approved of the chosen game and understood her explanation, glad she had managed to pull that off well enough for her to comprehend the basic rules.

“Otay den. Wet’s play. Once ebewyone ish weady…”.

============================================

Swap’s giggles sounded pretty and nice to the little one. The musical android and former ghost felt comfortable with her, smiling and content in her grasp, relaxing as she swayed with him, soothing his anxiety and shyness at Chara and Sans’ appearance. He even felt secure that Asriel was in Sans’ arms, knowing that the evil version wouldn’t dare to come out now.

Napsta was glad that she understood his choice of game, letting out a sigh once he was lowered back into her lap and not held aloft. The world was so much bigger now that he was tiny and heights seemed so much higher. His tensed muscles melted back into their relaxed state and he leaned back in her embrace, enjoying the gentle hug with her arms wrapped around him. He wouldn’t be able to topple sideways or frontways and fall from her lap this way. Hearing her question, the baby bot gave a deliberate, almost theatrical nod, so she could clearly see it. “Mm!”

Yes! Candyland. That one! Being understood was a rarity when you were a baby so he was relieved she had. And that his hand had pointed to the right game, as well. It was a bit of a gamble when you had limited control. He tended to move his limbs with intentions that they often ignored, doing something else or moving a different way than he wanted.

When Frisk explained the rules, he tried to pay attention, getting the general gist of it and hoping his baby brain didn’t forget or get confused. Snap asked if he wanted her to help move his piece and he shyly nodded a couple of times. “Aah-gah”

It almost sounded like the “Uh-huh,” he’d been going for, his mouth and tongue refusing to coordinate to make the exact sound.

He raised one of his tiny hands and inspected it, opening and closing the fingers clumsily, wanting to try moving the piece himself but unable to communicate that with words. He just hoped that if he leaned forward and reached out for it, Swap would put her hand over his and they could move the piece together, so it felt like he was doing it himself. That way he wouldn’t feel so useless and felt like he was participating.

Napstabot looked up at Asriel in Sans’ arms when the skeleton came in and gave him a floppy wave, along with a small smile. Yay, now everyone was here! They were ready to play. He couldn’t help but kick his legs gently in excitement, loving the feeling of being included and listened to. It was better than being left in a playpen with no attention.

He looked down at the carpet and Swap’s arms, though, not wanting to see Sans looking at him. He was sure he looked ridiculous to the man. He felt foolish in this tiny form. He prayed his body wouldn’t do anything embarrassing in front of the skeleton.

==============================================

Frisk and Napsta didn’t mind Sans re-explaining the game’s rules. His speech was a lot clearer than Frisk’s, that’s for sure. Plus, it didn’t hurt to go over them twice, to really ensure they all understood.

While he talked, Frisk dragged the box over and pulled off the cardboard lid, taking out and unfolding the game board, spreading it on the carpet in the middle of the group. She then took the handful of plastic pawns and the cards, setting them beside the board. “I fink dat’s ebweyfing” the girl quietly murmured, double checking.

Seeing what colour piece Chara chose, she hummed over the remaining pieces before picking the sunny yellow one. The pieces looked just like little gingerbread men. There were just enough for them all, four in total. One for Sans and Azzy, one for Swap and Napsta, then one for Chara and one for Frisk.

She leaned forward and placed her man beside Chara’s on the starting space before sitting back, lightly gripping her skirt’s hem and tugging it downwards towards her knees self consciously. She had to hide that diaper from Sans! It was embarrassing. Even though he probably already knew. The padding had emitted soft crinkles when she leaned forward then back again. But hopefully he wasn’t paying attention to that. She didn't even want to think about needing a change later. Or needing help with feeding herself at dinner and washing herself at bath time and...ugh. She shook her head to get rid of the thoughts.

==============================================

Napstabot hoped that Swap would choose the blue gingerbread man pawn, waving his finger in the general direction and uttering “Buu-uu”. After all, blue was his special colour and pink was his cousin’s.

He was pleased when Asriel grabbed the green piece. There were four colours: blue, yellow, green and red.

Now Swap just had to put their piece on the board and they would start. But who should go first?

==============================================

Frisk seemed to be thinking the same thing, since she looked up at Sans and asked him. “Sans, who gets to go fiwst? Do we go awound in clockwise owdew?”

It would probably be best to let the two littlest ones go first due to their short attention spans and the need to keep their attention and interest on the game so they wouldn’t wander off, get bored or distracted.

She smiled when she saw Sans put Asriel’s rainbow star paci in his mouth to stop the goatling trying to chew the game pieces, remembering what she had done with the Lego earlier that day. He looked so cute suckling on that. The rainbows suited him perfectly. It matched with the colourful crowns printed on his onesie. His Mickey and Minnie Huggies diaper puffed out the lower half of it, clearly visible that he was snugly padded. Frisk was really glad she wasn't wearing a onesie. Her brother was also wearing a bib that had some letters on it but Frisk couldn't read what they said. Not even realising she lost the ability to read.

The little girl looked at the card pile instead and reached out to pick them up, trying to shuffle them but instead dropping half the deck.

“Oops!...Mmmh!” She made a sound of annoyance. Why were they so slippery? Her hands and fingers were so stiff and more difficult to move than usual.

She leaned forward to begin picking up the fallen cards, only to have one or two slip from her other hand as she added them to the stack. Frisk frowned and put them down, looking towards Chara. “Sissy…tan chu help me? Da cawds awe all slippewy! And my hands and fingies awen’t listening to me”.

Once the stack of cards was shuffled and placed in view and in reach of the group, the first player could draw a card from the top and the game would begin.

Frisk looked at the sweets and candies on the game board, loving the bright colours and cute illustrations. It made her want to eat sweets, though and her mouth watered. “Sans, can we has candy aftew dis?” she asked, licking her lips.

If he was smart, he’d say no. Because they’d definitely ruin their appetites and not eat dinner if they filled up on candy.

[MyNinjaAcademia]

Swap nodded, smiling as she heard Napsta’s attempt at a “uh-huh”, just continuing to sway back and forth with him as she held him close on her lap, looking down, watching him opening and closing his hand. She… didn’t seem to put two and two together, not understanding what he was thinking. She just assumed he was curious about himself and his surroundings like most babies.

“Hm?” She perked up, blinking as she heard the baby’s noise, watching him wave his finger towards the pawn, listening closely, trying to figure out what he was saying. “Bluuuuuuuee…?” She repeated, reaching over and grabbing ahold of the blue piece, smiling. “You want this one?” She asked, bringing it down in front of his face to show him, before nodding, placing it down on the board.

Swap continued to sway, spacing out once more, lost in thought, just waiting everything to get settled and for the game to begin. She let herself relax, humming softly to herself, gently petting Napstabot’s head and cuddling him close… until something made her freeze.

Pressure.

She felt her stomach gurgle, churning audibly, making her tense up. It was sharp, and unexpected, a grunt escaping her lips, taking a deep breath, focusing on the feeling.

It was only there for a few moments, before dissipating, making her look down, eyes wide, startled. It had come without warning, and left without a trace.

She looked around, before shifting around as she sat, feeling the padding of the pull-up press against her skin, reminding her of its existence.

It was nothing, why had she been so worried? …Yet, she couldn’t shake the feeling, having a strange sense of unease.

She took a deep breath, closing her eyes, before exhaling as she once again began to relax, silent.

[Temmiedasithlowd]

Asriel smiled as he watched his sister's set up the game, it made him happy seeing how hard they worked just for this as soon they were set up and could not begin, Sans of course drawing his card for him and moving the piece.

-----------------------------------------------------------------------------

"Yeah we're gonna go in clockwise order kiddo." Sans nodded as he watched Frisk struggle with the cards for a moment before Chara helped her, which he was glad to see how well the two had come together as sister's, especially when trying to give their brother a good time in his regressed mental state.

"Sorry kiddo that's gonna be a no from me, if I let you rascals spoil your dinner you're mom would never let me hear the end of it. However, if your all good and eat your dinner I will consider letting each of you have a piece, but only if you all behave, and that goes for you too you little troublemaker." Sans teased as he squished Asriel's cheeks, making the baby goat laugh and giggle from behind his pacifier guard before going back to rhythmically sucking on it.

--------------------------------------------------------------------

"Okay frisk." Chara agreed as she began to help her sister shuffle the cards and after a tiny bit of trial and error the deck was shuffled and setting them in the correct spot they were finally good to go and could start actually playing.

Chara was a hair disappointed hearing Sans' no when requesting candy, she wasn't sure why it made her feel upset considering his logic was sound and it was responsible of him to say no, but regardless she still struggled accepting it.

[Strawberry Surprise]

The gentle swaying did wonders for keeping his anxiety and shyness levels low, Napsta finding it very comforting. He sighed and continued to relax with her holding him. He was so relaxed that he wasn’t even that bothered when she didn’t understand his grabby gestures toward the blue pawn. Oh well, he was getting used to that. People were bound to misunderstand more often than understand when you were a baby.

“Gah!” He made an affirmative sound when she tried to confirm the playing piece with him. Napsta’s face spread into a huge grin when she voiced the word blue, drawing out the sound. Yes, that was it! He smiled in satisfaction watching her grab the piece and show it to him then place it at the starting square. Swap Chara was good at making sense of him, it seemed. And it felt good to be understood. Even just sometimes.

Her continued gentle swaying kept the pacifying effects going, even with Sans being present to see Napstabot like this. The head pats were nice too, his snowy hair feeling like silken fluff to her touch. And the soft humming she made was a pretty tune, one he wished he knew and would try to remember. She had a lovely voice.

The baby on her lap heard her stomach gurgle but didn’t think much of it. His stomach made noises sometimes too. Either she was hungry or she had to go potty. Her body would tell her eventually.

The grunt she made had him worried for a moment that maybe he was leaning back too much on her belly and causing pain but he was too relaxed to sit forwards, slumped cosily in her grasp. He felt her shift beneath him and the babyfied android reached out to rub her arm sweetly. He hoped she was okay. He wasn’t too heavy, was he?

He could feel her tense up behind and under him but after some deep breaths, Swap soon relaxed again, leaving the bot confused and wondering…until his eyes were drawn back to the colourful game board and he felt a flurry of excitement, eager to begin playing.

Napstabot's mouth watered and a little bit of drool slipped from the corner of his mouth, dripping down his chin and onto his blue onesie. The sweet taste of candy called to his childish taste buds.

=================================================

Frisk glanced towards Swap Chara in mild concern upon hearing the small grunt from her, seeing the way she shifted slightly with the baby on her lap.

“Chu otay, Swap? If Napsta ish gettin’ too heaby, chu tan put him on the gwound in fwont of chu,” she told her.

Her eyes then shifted to look at Asriel, smiling at the sight of the fluffy baby goat monster and how happy he looked right now. She was glad they could involve him and Napsta in their game so the littlest among them weren’t left out.

She then saw Sans draw the first card and nodded, listening to him.

“O-otay”.

Frisk accepted that with no qualms. It seemed fair and made sense to go clockwise, like you did in most games. She was grateful for Chara’s help when the cards kept escaping her. It was almost like her hands and fingers were covered by ten pairs of gloves for some reason. They wouldn’t listen to her brain and moved more slowly and clumsily than she was used to. She’d just have to try to retrain those fine motor skills so she could get them back. Yeah.

Frisk looked up at Sans while Chara sorted out the cards, her mouth falling open as she let out a small sound of disappointment at his ruling about the candy.

“Aw. …Otay”.

She begrudgingly accepted that fact. Despite the letdown of him saying no, the logical part of her mind knew that it wasn’t good to fill up on sweets before dinner, so his ruling was fair. Yet it didn’t stop the disappointment and slight frustration from rising up inside her. It was gonna be hard not to feel like candy when the board’s illustrations made them look so appealing.

But she knew Sans was right. And she didn’t want him to get in trouble either. When he followed up the denial with an offer to let them have candy if they ate dinner and were good though, it pacified Frisk a lot and tugged a smile back onto her face.

“Otay,” she said much more brightly, “Dah sounds good. I will do my bestest to eat up allll my din din and…and be supew good,” Frisk promised.

A piece of candy wasn’t much but she’d take what she could get. She wondered what was for dinner tonight and recalled that there were leftovers from the roast, green veggies and cottage pie her parents had made for earlier meals. They could always be pureed for the younger babies. And they had that bag of apples from the kind lady too, so they could make something for dessert from those. That might be fun. Baking with Sans.

Frisk grinned watching Sans squish Azzy’s cheeks, giggling at his baby giggles. She could never get over how extremely cute he was. The pacifier bobbing in his furry maw was adorable to watch as well.

“Azzy, you’we such da cutest,” Frisk cooed. “Dat paci suits chu. It's got allll da colouws!”

She then looked to see that Chara had placed the neatly stacked game cards on the board and got excited for the game to start, leaning forwards a bit to watch as Sans moved Asriel’s gingerbread man a few squares along the winding pathway.

“Ooo, chu off to a good stawt,” she observed, seeing how many spaces the pawn went forward.

“Wet’s see if Napsta an’ Swappy tan catch up”.

Her gaze slid over to Swap Chara and the blue baby on her lap. “Youw tuwn to pit up a cawd, Swap,” she smiled. “Chu gotta help Napsta mobe da blue gingerbwead pawn since he's too little”.

Frisk instructed her helpfully, even if she already knew. Frisk was always trying to be helpful to those around her.

===============================================

Asgore and Toriel’s date was going well, the pair enjoying each other’s company and shared activities. Right now they were at the restaurrant. It would take a while. First, they were having entrees, then the main meal, then dessert and then they’d head to the cinema to watch a movie. After that, they were planning to hit up the arcade then perhaps a stroll through the botanical gardens. Maybe a visit to a hotel later on for some romantic shenanigans.

[MyNinjaAcademia]

Swap looked down, slowly relaxing, giving a small, soft smile as she watched Napsta rub her arm, taking a deep breath.

“I… I’m okay…” She tried to reassure him and Frisk. But… maybe putting him down for the time being wasn’t a bad idea. Gently, she lifted the android off of her lap, gently placing him down righg in front of her, gently petting his head immediately after.

Swap nodded her head as she listened to Frisk. She shifted about so that she was sitting on her knees, before starting to lean forward, reaching for the stack of cards… only to freeze.

The pressure she had felt only moments prior came back… sharper, and more intense. Before was just a warning, but now…

“I… I c-can’t…-!” She winced, scrunching up her face as she grunted, shuddering as she quickly gripped onto the table, trying to steady herself. The pressure was building and building, moving down quickly.

She felt a loud, long, rumbling bit of gas escape her… but it didn’t seem to help relieve it, only making it worse. Her eyes widened, shuddering as she felt a large, warm, mushy mass start to push out of her, pressing into the soft padding of her pull-up, making it bulge out, expanding visibly beneath her white tights, pushing out so much that it even started sagging below her dress.

Her face began to heat up, burning red, tears welling in her eyes, unable to stop her body as it helplessly pushed out her mess, filling up her protection… which wasn’t exactly made for this kind of accident, forcing it to press up against her.

By the time it was over, she was panting, completely silent, not knowing what to say or do, her bottom lip quivering, her entire body trembling.
