As Megumi awoke, she looked at the ground to see Dahlia back to her normal size as she said. As she stretched her arms she looked over to see Bella missing. She looked all over her room as Dahlia slowly awoke.

“Megumi? What’s with all the noise?” She asked as she got up and stretched.

“Have you seen Bella around here?” Megumi asked as she looked under the bed.

“Hm? I think she mentioned something about having a special surprise for you.” Dahlia told her as she looked around for her friend.
“That’s odd… she would’ve woke me up much earlier to tell me of her plan.” She said as Megumi picked her up.

"Well, we can look for her together." She told her friend as they heard a scraping noise and the sound of a certain doll girl struggling to push something. Megumi rushed over to Bella's aid as she pushes the strange device along.

“Hey there, thanks for the assist!” Bella said as Megumi set the dolls down and got the machine over to them.

“Bella, what is that thing?” Dahlia asked.

“It’s my surprise for Megumi!” Bella told them. "It's a cotton stuffing machine, I loved these things and it's been a while since I've seen one of these babies." She pats the machine's side.

“What does it do?” Megumi asked now curious.

"Simple, fill a plushy or doll with cotton stuffing. It doesn't get any simpler than that." Bella smiled brightly as Dahlia observed it.

“I do like to fill myself with cotton from time to time…” She said as her friend grabbed the hose and inserted it into her bottom.

"Ooh! I'm so excited, it's been forever since I've been able to do this." Bella mentioned as she looked around for the on the switch.

“I am too, though, do you mind answering a question for me?” The two looked at her, then at each other, before nodding to her.
“Why were you so willing to tell me about your defectiveness?” Dahlia intently looked at her before sighing.

“It’s because Bella can’t keep secrets to save her life.” Dahlia looked at her friend who awkwardly giggled.
“We also don’t like keeping secrets from others, it feels dirty trying to pretend everything’s okay with us when we know that’s not the truth.” The doll answered.

"Thank you, I appreciate someone who's honest. How about we promise not to keep secrets from each other?" Megumi held out her pinkie.

“We promise.” The two dolls said simultaneously as they held onto her finger.

"Thank you, now why don't you show me what this machine does?" Megumi asked Bella who excitedly located on the switch and flipped it on. Quickly bulges formed in the hose as cotton came rushing into Bella, her belly bulging outwards due to the sheer amount being pumped into it at once.

“That’s a pretty strong pump!” Megumi commented as she poked the doll’s staunch belly as it swelled with cotton stuffing.

“I remember now! Man, we had some great memories with this thing, where did you find it?” Dahlia asked hugging her friend’s rounding belly.

"It came as another package today, so I managed to sneak it out of your parent's sight when they weren't looking. They seemed rather confused as to why this showed up." Bella told the two as she proudly pats her belly as it jiggled full of fluff.

“You’re going to become a beanbag of fluff, does Dahlia have any limits to how big she can get?” Megumi asked.

“I’m shooting for as big Dahlia got last night.” Bella proclaimed as she could feel that her bum and breasts were beginning to join in on the growth. She collapsed to her knees as she was overcome with joy as Dahlia continued to rub her friend’s belly feeling how soft and squishy it had become.

“I love it when you fill yourself with cotton, your body makes the best noises.” Dahlia nuzzled her friend’s belly to hear it squeak.

“Ooh! I want to try!” Megumi poked Bella’s tummy as it squeaked causing a giggle to erupt out of the three.

"You're the best toys a girl could ask for," Megumi told the two as Bella's belly become bigger than the little girl's entire hand. Her breasts and butt were no slouch in the growth department either, quickly growing to impressive sizes in mere seconds. The dolly pressed her hands into her belly to feel how plush it had become. Her skirt was rising up revealing her underwear that was the same color and pattern as her stockings causing her to blush.

“Oops, that might not be appropriate for someone your age to see.” Megumi chuckled as she seemed to not mind in the slightest.

"Don't worry, there's nothing wrong with that, all girls wear them, don't they?" Megumi replied to Bella's worries as she pats her belly.

"I'm glad, I was worried there for a minute," Bella said now relieved.

“Worried about what?” Bella had to admit, she appreciated the little girl’s seemingly unbreakable innocence.

"I'm only wearing an apron, if she can handle me, I'm sure she can handle you," Dahlia reassured her best friend as she looked at her arms and saw that they too were swelling with cotton stuffing.

“I feel the next phase coming on!” Bella announced as her limbs began to slowly get enveloped by her body. She cooed with joy as her expansion showed no signs of stopping anytime soon. Megumi watched as her doll friend became an overjoyed blimp of her former self as more and more cotton was pumped into her. Her shirt rid up her belly as it covered less and less of her body.

“How much stuffing does that machine hold?” Megumi asked impressed at watching the machine continuing to fill her friend.

"We're not sure, we've never been able to see just exactly how much stuffing this thing holds," Dahlia mentioned as Bella's belly now served as a bed for the rest of her body.

“And today we’re gonna find out just how much this machine can really pump! I can really feel it today! Both mentally and physically!” Bella claimed as her hands and feet were now sucked into dimples on her body as her arms and legs were no more. Soon enough even her cheeks began to bloat up with the soft substance.

“Feel my cheeks, they’re now all soft and squishy!” Bella told Megumi. The little girl poked one of the doll’s pink cheeks and hear a familiar squeaking noise come from it.

“Adorable sounding as always.” Megumi smiled as she hugged the doll whose size almost surpassed the girl’s arm span.
“I can barely hold all of you with how big you’re getting…” Megumi told her as she tried to get a good grip on Bella.

“Well, I prefer it that way, I want to be your personal bed for when you need to rest or calm down, and the only way that’s happening is if I get bigger than you.” The doll’s response made Megumi smile with joy. At this point, Bella was nearing the height of Megumi's bed as her belly billowed beneath her bloated with the cotton filling and still going.

“I guess we should call you Big Bella from now on!” The child chuckled at her own joke while the dolls rolled their eyes.

"Psssh, like we haven't heard that one before," Bella told Megumi unimpressed by the girl's lack of originality.

"Yeah, we expect a little more effort here from your jokes," Dahlia told her.

"Then let me get back to you when I come up with a better joke," Megumi responded.

“Well, until then why don’t you-” A rip coming from Bella’s body was heard scaring the daylights out of the three.

"What was that noise?" Megumi asked worriedly.

“Let me check…” Dahlia wandered around until she found the problem.
“Uh oh…”Megumi looked over to see a tear in Bella’s skin had appeared and cotton was peeking out of it that grew bigger with each passing second.

“Gah! I sprung a leak! Quick, I need you guys to fix this now! I can’t have any cotton leaking out of me!” Megumi was quick to spring into action looking for a sewing kit around her room as Dahlia panicked trying to push the cotton back in.

“I knew we shouldn’t have tested your limits! Look what’s happened!” Dahlia was full of worry and regret as the tear was growing too large for the doll to handle.

"I found it!" The little girl announced as she pulled a kit out of one of her drawers and rushed over to Bella. Quickly and with precision, Megumi was able to sew the leak shut and keep all the cotton in her.

“Whew, thanks for the save Megumi.” The relief on Dahlia’s face was immeasurable.

“You’re welcome. I’ll keep this close by in case you spring any more leaks.” The child told the two as she set down the kit on her bed.

“Man, that was quick, how did you manage to learn skills like that?” Bella asked impressed by her owner’s skill.

“My grandma’s teaching me, she said I’m a fast learner.” Megumi bragged.

"I think I agree with her," Bella stated.

“I concur.” Megumi looked as Dahlia confused. "I agree," Dahlia told her.

“Oh! Got ya!” The girl smiled before looking back at Bella. Her shirt now only served as a bra for her plushy breasts as her belly was revealed in all its pillow-like glory. Her skirt was even more useless as her bottom long past surpassed her skirt’s ability to cover it, but luckily her underwear was stretched over her massive butt. As Megumi observed her she could see that the doll now surpassed her bed in height and continued to increase as her mass swelled.

"I'm gonna be honest with you Bella, I was not expecting you to be able to reach these sizes," Dahlia told her as she squeezed a bit of Bella's belly.

“Were you doubting me?” Bella accused her sounding rather offended.

“Well, yeah, but I think I owe you an apology here. I’m sorry for doubting your skin’s capabilities.” Dahlia gave her a big hug before she was picked up by Megumi and placed on top of her swelling best friend.

“Apology accepted. To be honest, I wasn’t expecting you to take two tugs of the string.” She was once again greeted by a flat expression from Dahlia.
“What? I’m serious- oh…” She awkwardly giggled as Megumi was once again left in the dark.

"Well, I guess we have our owner to thank for showing us that we can go beyond our original sizes." Dahlia smiled at Megumi who simply blushed.

"You're welcome." She replied as she faces planted into Bella's mass and nuzzled it causing her to giggle. Her body was now a few orbs on another with a head and dimples where her limbs were engulfed by her inflating flesh. Her body shook and quivered as cotton began to get pumped in large swaths as the machine was starting to reach its final legs. Her body pulsed as each pump blimped her body larger.

“Is the machine supposed to be making those noises?” Megumi asked as the machine began sputtering and skipping from time to time.

“I think it’s running out of juice. This thing does run batteries, rechargeable batteries luckily, but still batteries.” Dahlia remembered. Bella began deep breaths as each pump filled her with joy as her belly jiggled with each large chunk of cotton forced into it.

“This is the life, blimping larger than life for my best friends in the whole world. I couldn’t ask for more.” Bella said.
“There’s only one thing that could make this better…” She flashed a sly smile at Dahlia.

“What’s that?” She asked.

“You join me by my side inflating as buddies.” The brown doll requested.

"Woah, slow down there, I think you're more than enough for the day. We don't want to overwhelm our owner." Dahlia pats her friend.

“Fine, but we should totally do that.” Bella gave her that sly smile again.

"Perhaps some other time," Dahlia assured her.

"I would love that," Megumi commented. Just then Bella could feel the last pumps from the machine as it slowly powered down. Each pump still had the ferocity of the last as her body stretched out a last few inches. Her belly now rounded out and the stitching held true to its durability not letting a single bit of fluff get out. The last pump entered Bella as she swelled out once more. Finally, the machine ran out of juice and stopped pumping Bella.

“That was amazing! I want to do it again!” She said.

“Let’s slow down, you’re as big as I was last night. I guess we’ve really underestimated our body’s capacities.” Dahlia said.

“Perhaps we could go even bigger for you two next time!” Megumi told them excited about the possibilities with the cotton pump.

“Let’s slow down and enjoy our friend right now.” The little girl quickly hugged Bella as tightly as possible.

“Oh, that feels nice!” Bella stated.

“Hmm, there’s one thing I want to know…” Megumi backed up.

“Yeah?” Dahlia sat cross-legged on her friend.

“Where exactly did that machine come from?” Megumi asked.

"We don't remember, but it's come with us each and every time we've got a new owner. Guess your grandma forgot to send it." Dahlia explained.

“Good enough for me. Let’s have some fun before mom calls me down for breakfast.” Megumi said to the two.

“Absolutely! Shake me around, I love when people do that.” Bella stated as the three played the day away.
