Batty Over A Gem [Sonic RP]

The overgrowth of the forest near the Mystic Ruins remained the stay. All those leaves and bushes were covering a bunch of corners and pathways that lead to the rustic, but majestic temple made of stone. Of course, this wasn't too far for one traveler who was flying above the grassy labyrinth. She was sure to make it to the ruins this way by gliding with her purple, leathery wings.

It's the sexy, yet smart, sassy, seductive, and strong-minded young woman - Rouge The Bat. She's not just a jewel thief, but she's a world-famous freelance treasure hunter who was interested in jewels.

At this time, she was gliding towards the temple above the treetops just before she felt her wings getting weary.

"*Sighs* Oh my... My wings are getting tired. I need to land at the entrance of this temple." Rouge said as she was gliding into the entrance of the temple and landed softly on the ground. "Phew. Next time I need some lift or need something to make my flying without flapping my wings."

Luckily for her, she was already at the entrance where was next to the set of big stairway behind her.

"Alright. Let's see if there's a jewel I want to collect." She said as she started to climb up the big stairway.

Deep inside was getting a bit dark. The further down she went, the light from the opening was starting to fade away

"Hm-hm-hm... Good thing that I am nocturnal." She said as she's walking through the corridors of the temple. And after 10 minutes, she saw a ray of light, and it reveals the table with the gem. "Jackpot! I found it!"

She begins to pick up the pace by fast walking towards the source of light.

She's arrived at the table. "So, this is the gem where it hides inside of this temple," Rouge said and grabs the gem.

The gem appeared in the same color as her wings: purple. The way that lavender color shines onto her eyes.

"Oh~... So beautiful. This will be the first gem I've personally captured! This will be my first one for my collection." She said as the gem started to glow. "Wha-?"

It was emitting light like it was one of those siren lights from the police cars. Not only that, she felt a very strong force coming from it.

"Ugh! What happened?" Rouge groaned as she started to glow purple.

Her eyes were even swirling a bit, feeling hypnotized by the gem's luminous beams.

And after a while, Rouge snapped out of it. "Wow... What on Mobius was that?" She asked as she looked around at her body, and she sighed. "Phew... I don't know what happened to me. But I am glad it's over."

Suddenly, the glowing finally stopped.

"Well, I am glad the glowing's stopped." She said, and as she turned around, she felt something weird in her body.

She halted for a moment, placing her hand onto her belly.

"Ugh... I felt weird in my stomach." Rouge said as she felt her breasts are getting bigger. To her surprise, she felt her boobs were growing, due to how tight her heart chest-plate was getting.

"W-What?! My breasts... are growing!" Rouge gasped as her breasts are inflating, and they feel lighter. She touched them, and they bounced. They were feeling light as a feather, which made her felt weird. This resulted in her face being reddened by this sensation.

"Wow... They felt so light. This felt so weird." Rouge said as her belly started to inflate slowly, but then her butt inflates. "Oh, my, now what!?" she peeped, feeling a sudden change below her chest and behind.

She puts her hands on her belly and touches them carefully. "Oooo..." she muttered. And then she touches her butt and rubs carefully. And then she stood on her toes.

"Huh!?" she reacted, feeling like she was being drifted off from the ground. "I-I am floating off?! What's happening to me?!" She questioned, as her belly, breasts, and butt inflating as she floats onward the hole.

It didn't take long for her to finally be off the ground like two feet away as she felt herself getting bigger and rounder. "Wow, wow, wow... I'm floating off." Rouge whimpered as she floats higher, and flies through the hole, and she's outside the temple.

She was getting bigger than a yoga ball while her body's girth was spreading incredibly fast. "Ugh! My body is still inflating! How did that happen- *then she realizes* Oh, that gem!" She's looking at the gem that she held in her hand.

While her hand was grabbing hold of it, her limbs were getting puffed up. Although, her belly, chest, and bottom were the ones getting bigger in comparison. She was now reaching beyond the size of a wrecking ball, which was quite astounding. The fact that she's still growing, her suit isn't showing any sign of tearing up.

”Did that gem inflate me like a balloon?!” Rouge questioned as she's looking at the gem. Then she thinks maybe inflating is not such a bad idea.

So she throws the gem into her cleavage, and the gem keeps glowing and Rouge keeps inflating. "Jackpot," she cheered softly, going past the wrecking ball size. And just in time, that her arms went outwards, and they become stiff. The same goes for her legs. Her belly inflates bigger than her breasts.

"Oh, yes..." she moaned with delight, feeling herself spreader further outward. Then her spine started to bulge, and then her butt, belly, and breasts inflate together into a huge round blimp and her arms and legs sink in her giant inflated body. Some bones were popping during the process. "Oh! Oh!" reacted the bat from her bones. Finally, the last bone popped. "Oh, that's lovely..." she sighed with utter relaxation.

Then she felt she inflating bigger and saw the view of the Mystic Ruins. She floats higher. "Wheee!" cheered the excited bat, flapping her wings, which did nothing for her in this condition. As she’s inflating, she reaches among the clouds in the sky and now inflating bigger to the half size of the temple.

As she’s inflating, she reaches among the clouds in the sky and now inflating bigger to the half size of the temple. Then her floating ceasing, but her body is still inflating bigger.

"Mmmm... Still feel so good. I hope it never ends like this." Rouge said, as her body is now reached to the size of the Mystic Ruin temple. Her limbs and neck were imploding during the process. Her tail, hands, feet, and head are remain deflated, as her hands flail. She even hiccuped, which caused her bigger body to jiggle.

Now she's five times bigger than the temple where she found that purple gem. "Wow... I am way too huge. Still, it felt so good." She said as her body keeps inflating. Suddenly, the wind was starting to pick up the pace. As she was now way above the temple, she felt her whole body drifting away along with the gentle breeze.

"Wow... I'm flying off away." Rouge said. "Well, I am glad that I can fly without flapping my wings." For that matter, she never had to flap her wings. "Well, for now, I think I need to relax while I was getting bigger and nothing to worry about," Rouge said as she inflates bigger and floats higher.

A little later, a plane's flying through the clouds. The sound of its engines caught the ballooned bat's ear.

"Hmm? It sounds like a biplane." She said as Tornado with Sonic and Tails is approaching to giant blimp Rouge.

"Sonic!" Tails yelled while he was piloting the plane with his helmet and goggles on. "What is it, bro?" Sonic reacted as they spotted the bloated side of the bat. However, at the time, they didn't see her as their friend.

"Wow! What in the world is that thing?!" Sonic questioned.

"You don't think it's another Death Egg, do you?" Tails wondered, feeling worried.

"I don't know, buddy," Sonic replied, as he's looking up, and saw the wings. "But man, those wings looked familiar."

"Why would Robotnik put wings on a Death Egg 2.0?" This two-tailed friend responded, looking confused.

"That's indeed a question, Tails," Sonic replied as he's looking it around.

"Shall we keep following it in case it might do something disastrous?" The fox suggested.

"Yeah. But we don't know if that's Death Egg that Dr. Eggman built it. We have to look around them." Sonic said. "Good idea," the fox reacted as he dived the plane aside.

As they're looking around in 5 minutes, they hear a voice behind them. "Hey, boys!" That ringed right into Sonic's ear. Sonic and Tails' eyes widened that they hear a voice, and it came from... ROUGE?!

"What the!?" sputtered the blue hedgehog, rubbing his eyes. "Is that..." Tails stammered and saw her face, and then her whole body of giant ballooned bat. "ROUGE?!"

"Yes, Tails," The bat nodded. "Hello, Sonic."

"Rouge?!! How did you get up here?! I mean, what happened to you?!" Sonic questioned.

"Long story, but..." the bat chuckled.

Tails twitch his ears, and he hears squeaks from her body... "Are you... inflating?"

"Yes, but very slowly," she mentioned.

"How did you get so big like this?!" Sonic questioned.

"This gem," she said, which on her giant breasts, and the gem is stuck between them.

"Did that gem inflate you with its power?!" Tail asked.

"Yes," The bat replied.

"Wow... That gem sure's making you bigger, Rouge. How long will you stay like this?" Sonic asked.

"I have no idea," she said, trying to shrug, but couldn't. When she did that, it made her body squeaked loudly. "I guess as long if I hold this gem, I can inflate bigger, and bigger than Death Egg." Rouge guessed.

"That's what we thought you were at first," Tails giggled. "Yeah, and I saw your wings, and I suspected that it was you all the time," Sonic said. Hearing that made the bat laughed. She was quite amused that the boys would have that as their initial thought.

"You know... If I keep inflating... I might end up in the space." She said but has no worries. "And you're not scared?" Sonic reacted while the fox continues to pilot the Tornado, but presses the Autopilot button, and flies with his swirling two tails and floating into Rouge's gargantuan breasts.

"Heh, why shall I?" Rouge asked as she floats off higher. "How can you breathe up in space?" Sonic wondered as Tails landed on Rouge's breasts which makes her blushed and giggles, and scan the gem with his scanner.

"Interesting. This gem gives her cause her not just inflating, but it can make her breath in the space, too, Sonic." Tails explained after he scanned the gem as he notices he felt her breasts are still inflating and jumps off and flies towards his Tornado.

"So, I can breathe in the space with this gem, huh? Aw, so glad that I found this baby." Rouge said. "Well, that explains it," the blue hedgehog responded.

"But what about you two, boys"? Rouge asked. "We don't know if we can breathe in space, so we stay here on Earth while you're taking a flight in space, Rouge," Sonic said.

"Alright then," she said, trying to shrug again as she felt that she's started floating higher.

"Please be careful up there, Rouge!" Tails shouted as Rouge floats higher above the clouds and heading into space. "I will, thank you," The bat said.

10 minutes later, Rouge who was still inflating, and take a deep breath and exhale; she can breathe in the space, she's now outside of Earth and now floats in space. "Wow...." She sighed. "I really CAN breath in space!"

She's looking at Earth and saw a grand view of it. "What an amazing sight," she smiled. "This brings back memories in the Space Colony ARK." She felt she almost reaches the half-size of Earth, and miraculously, her spandex suit hasn't been tearing up yet.

"And I almost big as a planet. I don't know how bigger I can inflate." Rouge said as she then turned to see the moon. "Oh~... So pretty. I am as big as the moon." She said.

When she got close, she can see that the sun behind her was casting a shadow onto the moon like an eclipse. "Wow, I think I am gonna casting myself onto the moon like an eclipse. Hehehe. That shall be fun." Rouge said.

And when she got a bit closer, she's behind the moon and cover the whole sun and creates an eclipse. "YES!" She yelled victoriously.

She saw the whole planet is covered by a huge shadow of a nearly-planet sized bat.

"Fear me, citizens!" She cackled like if she was some dastardly villain, and then smiles playfully at Earth.

A little later, Rouge stopped inflating, and she's bigger than Earth. With that, her whole body was massive. Her suit was still in tack while even her heart-shaped breastplate stretched as well. Her arms, legs, and neck were finally imploded, leaving only her hands, feet, and head.

"Ohhhhhhhhhhhhhhh..... So huge... I think I can't move an inch, except I am floating around in the space." Rouge said. When she flapped her hands, kicked her feet, turning her head, or even attempt to flap of incapacitated wings, they squeaked real loud. Being this massive was making her face stay pink from her pleasuring condition.

"Mmmm... I wonder how long I have to stay like this?" She wondered. Not to mention how long has she been inflated.

Then at her humongous breasts, the gem stopped glowing.

"The gem stopped. I guess its energy's fading. But that also means- HMM?!” She said as deep hissing noise was heard. Her expression turned into shock, and then pain as her face turned blood-red as the batgirl's swelling body, and she grew bigger and bigger.

Rouge blushes deeply as she grows more with her cheeks bulging out bigger, as she continues growing rapidly while her body makes stretching sounds.

"Now what!?" she gurgled.

Rouge couldn't hold it anymore as she opens her mouth, and-

FWOOSH!!

She starts zipping all around in the space as the magical air gushes out of her. In a flash, she was zooming about. She flies around the circumference of the world until she finally went down into the atmosphere. As Rouge's body started to deflate rapidly, she was zipping down towards Mystic Ruins as arms and legs re-emerge back. Due to the speed of her zooming phase, she could feel herself getting hotter and hotter. She felt like a fireball came through the sky and hits Mystic Ruins.

After a massive explosion, it creates a cloud of dust. And as the dust fading away, Rouge was fully deflated, except her belly who looks 9 months pregnant.

"Oooooh..." she moaned, feeling some areas being half charred, including parts of her attire that got some holes from the burns.

Rouge standing up, and looking around, and figure out that she came back.

"I... came back." She said, and then looking at her belly who was still inflated. "Oh," she responded, poking at her stomach.

"Hmhmhmhm... At least my belly is still inflated." She said and rubs it gently, and when she saw the gem and picked it up. "Well, I shall take this gem with me to my collection. And maybe one day, I shall inflate again." She said.

Just then, her bloated stomach rumbled. She felt hungry.

"Oh, I'm getting hungry. I guess it's time to heading home." Rogue said as she flaps her wings, and flying towards the sky as her adventure as the universe's largest bat balloon is over... Until next time...
