Good Fortune

Miss Fortune, infamous cat burglar with a heart of gold; expertly flipped through the air and landed on the rooftop.  Just in time to see her sometime ally, sometime enemy; and either-way boyfriend, The Comet; swell up like a balloon.  As she watched, his entire body thickened, rounding out like a parade float, and then his belly burgeoned forward, pulling the shirt of his spandex outfit out of the tights, and as she watched, stunned, his chest took on a barrel shape.
"What the hell is going on here?"  She cried, putting her hands to her slender hips.
"Fortune?"  The comet said, trying his best to turn his head, but not having much luck in his bloated state.
"I'm fattening up your boyfriend."  A female voice came from the other side of the rooftop.  Miss Fortune leaned to the side, looking around the much wider than usual form of The Comet, to see a cartoonishly voluptuous woman standing on the other side of the roof.  Long black hair streaked with red framed her face, but Miss Fortune's eyes were quickly drawn to her chest.  Her breasts were the size of small beach balls, and her buttocks were equal in size.  Her figure was even more eye-catching in her blue and black latex catsuit, tied together with a red belt.  She was pointing a strange looking gun at The Comet.
"Careful Fortune," The Comet said, "that ray of hers is really hard to avoid."
"Apparently."  Miss Fortune said, walking up behind The Comet, careful to keep him between herself and the mysterious villain.  
"Come on, we're both thieves here."  The woman said.  "Do you really want to end up all blimped out?"  Miss Fortune shrugged, coming up behind The Comet and squeezing his sides.  He gasped in shock, unable to see what she was doing, and she smirked, suppressing a giggle.
"I don't know, is this reversible?"  Miss Fortune asked.
"He'll shrink down in about an hour."  The woman responded.
"What are your plans?"  
"I was thinking of robbing the bank up the street, fattening up a few people along the way."  Miss Fortune thought for a second, then shrugged again.
"Sounds good to me."  She responded, stepping out from behind The Comet to look him over.
"Fortune!  What are you doing?"  The Comet asked.  Fortune just shrugged again, grinning at him.
"What?  You're the superhero."  She told him, sticking her tongue out at him.  The other woman sauntered up, putting her hands on her hips as she looked over The Comet as well.
"I just love balloon boys."   She said, smiling.
"He is pretty cute like that."  Fortune agreed.  The Comet just looked back and forth between the two in frustration.
"I'm Airiel."  The woman said, extending a hand.  "But like A-I-R-iel."
"Nice."  Fortune responded.  "Miss Fortune."  The thief said, shaking her hand.
"Want to join me on this bank job?  I'd love to work with a celebrity like you."  Airiel told her.  Miss Fortune laughed.
"Maybe some other time, I do like your style.  But right now I want to play with my… what did you call him?  Balloon boy."  Fortune responded, laughing.  The Comet gave her an anguished glance, and Airiel just smiled at her.  
"I understand."  She said, and began to turn and saunter off.  "Well…"
"Actually, wait a second."  Fortune said.  "Do I have to worry about him popping?"  She asked.  Airiel paused, and even just the act of her turning back to face Miss Fortune caused her inflated bosom to wobble.
"No."  She said, shaking her head.  "He's tough enough you don't have to worry about sharp objects, and there's no upward limit with this thing."  She said, patting her raygun.  Miss Fortune put a finger to her lips, thinking.
"Really?  Well, in that case, could you?"  She puffed her cheeks out and gestured with her head towards The Comet.  
"FORTUNE!"  He cried, wobbling around but not really moving.  Airiel just smiled, turning and drawing her ray.
"Of course."  She replied.  Miss Fortune stepped out of the way, and Airiel leveled her gun at Comet and pulled the trigger.  At first Miss Fortune didn't think anything was happening, but then he started to get even larger.
His torso began to bulge outwards, and his limbs became cone-shaped.  His eyes were wide as he looked back and forth between the two women in panic.
"This is great!  Look at him!"  Fortune shouted, laughing and clapping her hands.  The Comet wobbled his arms and rocked back and forth, but didn't accomplish anything.  He began to look like a ball with fat arms and legs, a large band of skin between his shirt and pants.
"How big do you want him?"  Airiel asked, turning her head to look over at the slender thief, while keeping her ray trained on the bloated hero.
"I don't know, how big can you make him?"  Fortune asked.  The Comet looked at her pleadingly, and she just smirked back at him.
"I like the way you think."  Airiel said with a laugh.  "I don't know to be honest, it seems to go pretty big."
"Oooh."  Fortune said.  "Just think babe, you're gonna be the biggest hero in the city."  She said, laughing.
"You're enjoying this way too much."  The Comet groaned.  He was beginning to take on a squared shape, as the sphere of his body began to assimilate his limbs.  The gravel on the rooftop crunched as his feet were pushed further and further apart.
"You should see how big I got my boyfriend."  Airiel told Miss Fortune.  "He was so big he completely filled the bedroom.  He hates it when I do that, but really he doesn't."  She said.  Fortune giggled.
"If I had a ray like that, I don't think I'd ever let him deflate completely."  She said.  "Make him walk around with a big round belly all day."  She arched her back and reached out in front of her to show how big she would make his belly.  The Comet just shook his head sadly.
"Oh I know."  Airiel responded.  "My boyfriend has to tell everyone he got fat, even though he's still in great shape.  I love it when his buddies give him shit about it."  She giggled.
"Can you imagine that babe?"  Miss Fortune asked.  "Having to tell everybody I fattened you up, when really you'd just be full of air?"
"Please, make her stop."  The Comet groaned.  The comet was just a ball with a head, hands, and feet now, still growing rounder and rounder.
"Oh fine, you big baby."  Miss Fortune said.  "That big enough."  She sighed.  Airiel smirked and holstered her raygun.  Miss Fortune, making sure she wasn't walking into the line of fire, ran up and jumped onto The Comet's chest.  She wrapped her arms around his head and pulled him forward, so he was laying on his stomach, his head just a bit over hers.  "Oh my God, you're huge!"  She said, reaching up and kissing him lovingly.  When they separated The Comet just smiled at her and shook his head.
"You're weird, you know that?"
"I am, but you love me anway."  She said, smiling back at him.
"Yeah, I do."  He responded, and they kissed again.
Airiel just smiled and shook her head at the two lovebirds, then turned and began to saunter away.  She still had a bank to rob on her to-do list, and she didn't have too much longer before her own enhancements wore off.  Just as she was about to reach the edge of the roof, she was stopped by a cry of "hey, wait!"  She turned, her bosom wobbling with the motion, to see Miss Fortune jogging towards her.
"Hey, thanks for doing that."  She said, gesturing to the helpless form of her boyfriend on the roof behind her.  
"It was my pleasure."  Airiel said with a smirk.  Miss Fortune just grinned.
"That will wear off, right?"  She asked.
"Oh yeah, in about an hour, I swear."  Airiel said, putting her hand over her heart.
"Cool.  Hey, do you think, before you go, you could…" Miss Fortune began, Airiel gave her a quizzical look, so she puffed her cheeks out and put her arms out to her sides.
"Are you sure?"  Airiel asked.
"Yeah.  I'm dying to know what it feels like."  Fortune said, grinning from ear to ear.  Airiel grinned as well.
"Ok."  She replied, drawing her raygun.
"Wait."  Fortune said, holding up a hand.  "Let me get over by him, make me… oh… a little bigger than him, so I can lord it over him."  She said with a smirk.  Airiel grinned even broader and nodded.
"Thank you so much, hopefully I'll see you again."
"Yeah, you too, this was a lot of fun."  And with that, Fortune waved and jogged back over to The Comet.  She reached up and put her arms around his neck again, kissing him.  Airiel smiled and pointed her gun at Fortune, then fired.
"I have one more surprise for you."  Fortune told The Comet, when they separated.
"What now, you're gonna turn me into something else?"  He asked, shaking his head at her.
"Nope.  My turn."  Fortune said, smiling.
"You're absolutely crazy."  The Comet told her.
"I know."  She replied, still smiling.  Just then, her belly bulged out, and she pressed it against The Comet's expansive chest.  "Oh wow."  She moaned.  The Comet just smiled down at her as he watched her swell.  Her breasts pushed outwards, straining against her costume and creating a canyon of cleavage that quickly rivaled Airiel's.  Her hips widened, and her ass pushed out behind her.  She slid off the hoodie she wore over her costume and let it fall to the roof, and Comet could see her arms puffing outwards as well.
"Just think baby," The Comet whispered.  "You're going to be the biggest thief in the city."  Fortune giggled and leaned up to kiss him, the front of her bloated body pressing against his as she did.
"Tell me about it."  She said.  Her midsection had become a sphere now, with her hugely inflated breasts pressing up against her chin.  She kept her hands locked together behind Comet's head, doing her best to keep their heads close together as her belly pushed her further away.
"Can you imagine if your friends saw you now?"  Comet asked her.  "They'd all think you'd gotten fat."  Fortune just bit her lip and moaned.
"Stop that."  She said.
"You can't possibly be getting turned on by this."  The Comet said incredulously.
"What can I say?  I'm as surprised as you are."  Miss Fortune moaned, looking up into his eyes.
"You are so weird."  He said affectionately.  She leaned up and kissed him again, but this time the kiss was broken by her body pushing the two of them apart.  Her hands shot out to her sides with a slight "fwoomp" noise as the pressure got too great.  She grinned up at him as she took a few steps back.  Her breasts were little more than slight hills on the huge sphere of her torso now, and she was beginning to take on the odd slightly squared shape as she became more rounded.  Still grinning broadly, Miss Fortune leaned forward, then fell on to her belly.
"OOF!"  She exclaimed, bouncing slightly and bumping her head into the curve of what had once been The Comet's shoulder, which then caused him to rock back and forth.
"You ok?"  He asked, laughing.
"Yes."  She said, sheepishly, her head rising closer to his as she took on a more rounded shape.  She got bigger and bigger, until finally she was larger than he was, her hands flapping giddily on either side of her hugely rounded body.
"Goodbye!  See you around."  Airiel called from the edge of the roof, and then she was gone.  
"She was nice."  Miss Fortune said.  The Comet just sighed.
"She was not 'nice', she was a criminal who turned us both into human balloons."  He replied.  "She could have been lying about this wearing off, you know."
"You worry too much.  Just try and enjoy yourself."  She responded.  The Comet sighed and shook his head.
"You know…" He said after a moment.
"What?"  She asked.
"I'm gonna deflate before you do, and when I do, you are gonna get it."  He teased.
"I can't wait."  Miss Fortune said, biting her lip.
