"Tails' Bunny Balloon Expansion"
a Sonic the Hedgehog fanfic by Inflationcouplingist

Tails was in his lab one night examining his special, helium like gas he created one day. "Hmm...it seems the gas has a different compound structure." he said as he placed a hose connected to the gas into an organic belly model and watched it bulge. "It seems to be able to make the body bulge out..." He then thought of an idea. "Would it work on a living being?"

"Hey Tailsy." Cream greeted as she came up to him and hugged him from behind.

Tails blushed as he was hugged, but he smiled. "Hey Cream." he greeted shyly.

"What'ch doing?" Cream asked cutely.

"Well, just figuring how my new gas works." Tails explained. "The only thing I've came up with is that once inhaled, it inflates the body dramatically, well time wise of course."

"Inflate?" Cream asked. "Into a balloon?"

"Possibly, but I'm not sure really." Tails replied. "I might test it out, but I need a test subject to do so. But I really don't prefer using them."

"Why?" Cream asked.

"Well, I don't use them in any experiments that aren't machine related." Tails explained. "If I did...they might be becomes freaks and also think I might be like Eggman...maybe worse than him." He looked away from Cream, sadly.

"Oh Tailsy...I don't think you're worse than Eggman." Cream said, comforting him and giving his head a kiss. "Besides, I might not be mad if I tried it out."

"HUH?!" Tails gasped, shocked by what Cream told him and falling off of his chair.

"Are you okay?!" Cream asked, helping Tails back up.

"I'm fine...just a little shocked." Tails said, getting back up.

"Why?" Cream asked.

"You wanting to be my test subject." Tails answered. "But why do you want to Cream?"

"Well, it's someone you know, I wouldn't mind." Cream explained. "Plus...if anything does go wrong, I wouldn't blame you..." She held Tails's hand and looked at him. "And if it does go wrong, I'll be taken care of by you."

Tails blushed as Cream held her hands and looked at her. "Man... why do you have to be so cute?" he asked.

Cream blushed and giggled at being called cute.

"Al...Alright Cream." Tails said. "You can be my test subject."

"Thank you!" Cream exclaimed happily. "But would my dress and undies form around me?"

"Not really." Tails said. "But I do have a spray that'll make your dress form around you like rubber while still keeping it's cloth texture."

"Okay." Cream agreed. "But what about my panties?"

"I've tried it on all clothes, but boxers, briefs, and panties doesn't seem to work, but a diaper was the only type of underwear that it would work on." Tails explained.

"A...diaper?" Cream asked.

"But when I combined a pair of panties and a diaper together, they formed into some sort of diaper panties, and it became stretchy." Tails added. "Course, I'm still calling them panties."

"Okay." Cream said.

Tails sprayed a can of his gas onto Cream's dress and checked to see if it became streachy, which it did. He then handed her the panties he mentioned.

Cream looked at the panty diapers she was given and replaced her own with those. She smiled as they almost felt like they were snuggling her little girl bottom.

Tails grabbed the air tank with his gas and a hose and came to Cream. "You ready?" Tails asked, holding the hose.

"I'm ready." Cream said.

Tails gave Cream a kiss on her cheek and plugged the hose into her mouth. He went to the air tank and turned it on.

Cream blushed from both the kiss and feeling the gas going inside her. She waited for something to happen to her, until she felt her belly bulging and getting bigger.

"Wow..." Tails responded, seeing Cream's belly inflate and biggen. "Seems the gas is adapting to its new environment." He took a notepad and wanted to write something down, but something in him told him he was guilty about doing it to her.

Cream looked confused at Tails as her back and sides bulged and inflated alongside her belly, her dress and panty diaper's forming around her growing body.

Tails continued to look at Cream guilty like and not saying a word.

Cream continued to inflate and biggen, her arms and legs bloating and also sinking into her growing, round form as her dress and panties form around her like second skin while still being comfy.

"Man...why did I have to create that gas..." Tails said, his head turned down.

Cream felt her groin touch the floor, lifting her feet off of the ground and making her grow to 80 cm (2ft 7in), but before she could get bigger, she popped the hose out of her mouth. "What's wrong Tails?" she asked.

"Here I was testing out an experiment, but now I feel I created an disaster." Tails told Cream.

"You mean...me?" Cream asked.

"No...I meant the gas." Tails answered. "I thought I was creating something new, but instead I created a disaster...and used it on you." He turned away from Cream and frowned.

Cream looked at Tails and amazingly groin waddled over to him. "Tails...I think you're gas is a success, and I don't blame you for this." she said.

"Well...you might..." Tails said. "But anyone else..."

Cream gave Tails a kiss on his cheek and nuzzled him. "Hey, it's alright." she said, purring and trying to comfort him.

Tails looked at Cream and smiled, hugging her big, round, balloony body. "Thanks Cream." he said, kissing her cheek and nuzzling her head.

"You're welcome." Cream replied, smiling as she purred.

Tails continued to hug Cream, feeling how soft she became. "My...you're so soft and round." he said.

"Hehehe, like a pillow for you?" Cream asked, giggling.

Tails smiled and lifted Cream up with ease.

Cream giggled as she was in Tails's grasp. "I'm more like a toy than a pillow." she giggled.

Tails giggled back as he held Cream high. "Hope you mind if I keep you then?" he asked.

"Keep me?" Cream asked.

"Well...I-I..." Tails stammered, but then he felt his nose kissed.

"I would love it if you did." Cream told Tails, smiling and blushing.

Tails pulled Cream in and hugged her, rubbing her round back while also sneaking a peak at her lower half.

Cream blushed as Tails tried to look at her lower half. "You like my new bottom?" she asked, smiling.

Tails blushed madly from hearing that. "Uhhmmm...w-w-well..." he stammered.

"It's okay if you do." Cream reassured Tails. "But would you like a better view of it?"

Tails blushed madly and smiled goofly. "Y-Y-Yes..." he said.

Cream waddled away and tipped herself, giving Tails a better view of her panty diapered covered butt and wagging her bunny tail.

Tails immediately hugged Cream's panty diapered butt and nuzzled it. "Mmm...so soft and big." he purred, kissing her butt.

Cream blushed madly as her butt was kissed. "Oh stop it Tailsy..." she said, smiling. "You're gonna make me cry."

Tails tipped Cream back onto her groin and hugged her from behind, purring as he snuggled her.

Cream nuzzled Tails's cheek and purred as she was hugged. "You like?" she asked.

"I love." Tails said.

Cream giggled as she nuzzled Tails. "Mmm...wonder what you'll do with your new balloon bunny?" she asked.

"Well maybe bounce, feed, roll, cuddle, bathe, basically I'll just pamper you." Tails told Cream.

"Ooohhh...I'm gonna enjoy all that!" Cream said, smiling.

Tails smiled, but he then yawned a bit. "Aww man...I wanted to enjoy my new bunny balloon." he wined.

"It's okay Tailsy, you can sleep with me." Cream assured him. "Besides, I...*yawn* I'm a lil tired myself and all I want to do is sleep with my fox boy."

Tails smiled as he turned Cream to his facial view. "Then you get your wish." he said, grabbing and hugging the bunny balloon as he took her away.

Cream smiled and nuzzled Tails as she was carried out of the lab. "Mmm...I'm gonna get used to this." she said.

"Me too." Tails replied, carrying Cream up to his bedroom. He flew up to his bunk bed and placed her down. He flew back down, but came back up with a bunch of extra pillows and blankets he had in case anyone came over. He quickly made a bed of pillows and tipped Cream onto them.

Cream wiggled herself onto the pillows, getting comfortably.

Tails removed Cream's gloves, shoes, and socks before he removed his gloves, shoes, and socks. He laid on top of the bunny balloon and covered himself and her with many blankets, almost burying themselves in them.

"Comfy Tailsy?" Cream asked, smiling.

Tails snuggled Cream like a teddy bear, purring.

"I'll take that as a yes." Cream giggled.

Tails laughed a bit before he looked into Cream's lovely brown eyes, his nose touching hers.

Cream smiled and blushed as she touched noses with Tails's and stared at his light blue eyes.

"Cream..." Tails whispered. "You have such pretty eyes."

"Thank you." Cream whispered back. "And you have such handsome eyes as well."

Tails slowly drew his head closer to Cream's head and slowly closed his eyes, his lips touching hers.

Cream slowly closed her eyes as she kissed Tails, her ears wrapping around his head.

Tails cradled Cream's head gently as he kissed her, wrapping his twin tails around her.

Cream slowly broke the kiss as she sleepily stared at Tails. "I love you Tails." she whispered.

"I love you too Cream." Tails whispered back, staring at her sleepily while smiling.

Cream snuggled between the pillows and Tails before she nodded off, smiling.

Tails snuggled Cream gently before he nodded off to sleep, smiling.

*15 years later*

Tails was in his re-designed lab, doing research on his computer. "Okay...if I can get this new elemental compound to..." He stopped mid-sentence to find his twin tailed, baby balloon fox daughter snuggling his lap.

Vanilla Prower, named after her grandmother, cuddled her father's lap, cooing and purring.

Tails smiled at his daughter and patted her. "Maybe this research can wait." he told himself as he got out of his chair and cradled his balloon of a daughter.

Vanilla slightly woke up a bit to see her father carrying her. She smiled and cooed like the baby she is.

"Let's get to bed sweetie." Tails said. "Maybe you can sleep with me, Cream, and Amaddy." He carried Vanilla out of his lad and to his and Cream's bedroom.

Cream, at the moment and now a balloon her mother's height and head looks, was snuggling her and Tails's 2 year old rabbit son Amadeus Prower, named after Tails's father and called Amaddy for short.

Amaddy giggled as he snuggled his balloon of a mother.

Cream giggled from her son's snuggling. "Hehehe, a playful scamp aren't ya?" she asked.

"Uh huh." Amaddy replied, but then yawned a bit and became a bit sleepy.

"Aww...my son tired?" Cream asked. "Here, cuddle up on me."

Amaddy cuddled against his mother like a big pillow. "Mmm...mama big and soft." he said.

Cream smiled as she snuggled her son.

"Mind if we join you?" Tails asked, coming in and carrying Vanilla.

"Hey honey." Cream greeted. "Hi my lil Vanilla."

Vanilla giggled as she nuzzled her mother.

"Dada!" Amaddy greeted, hugging him and Vanilla.

"Hey my lil boy." Tails greeted, hugging him back.

Cream smiled. "You wanna cuddled up?" she asked. "It seems it's their bedtime."

Tails smiled and placed Vanilla down gently next to Amaddy. he then scouched Cream up onto them, blanketing them in her balloony warmth.

Amaddy and Vanilla snuggled up against their mother before they yawned.

"Goodnight my children." Cream said, kissing their heads.

"Goodnight my kids." Tails said, kissing their heads.

Amaddy and Vanilla smiled and nodded off, snuggling their mother's giant belly like a pillow.

"Tails." Cream responded. "This is precious."

"It is." Tails replied. "I hope we can be like this forever."

Cream smiled before he planted Tails a kiss on his lips. "I love you my fox hero husband." she said.

"I love you too my bunny balloon wife." Tails said, kissing Cream back before they nodded off in peace with their children.

Since that day, those two, now four, were never any happier than they already were.
