It's not a Party without Balloons

"H-Happy birthday, Purple..." Fluttershy rehearsed to herself.

She had been planning this birthday present for Purple for a couple weeks now, and the day had finally come. Purple would be home soon, and Fluttershy would be able to surprise her lover. Her idea was simple, inflate her boobs until she could barely move, and let Purple do whatever she wanted with them. Fluttershy grinned. Purple was going to love this. But... As she looked down... She felt more... Mobile. They were heavy knockers, sure, but... The idea was to be practically stuck in place.

"Hmm... I'm sure a little more air won't hurt..."

She could fill them more, definitely. She eyed the air tank that was in the corner of the room. She leaned forwards, pressing her tits against the floor, and began to use her body weight to push her bestial tits. Her sensitive flesh rubbed against the carpeted floor, causing her to blush. With anticipation. She quite honestly loved the feeling of her breasts being inflated to huge sizes... Of course, she'd never admit that... Only to Purple had she ever said anything about it. She reached the tanks, and prepared herself. It was difficult, but she managed to grasp tightly onto her massive inflated tits, and pull the tip of her nipple close enough for her to stick hoses into each of the nipples.

"Just a little bit bigger... And then they'll be perfect." She thought, her face reddening more. She turned the valve for the air tank... And yet, they didn't swell.

"Huh..?" Fluttershy turned the valve a bit further... And yet her boobs stayed at the same size.

"O-oh, must be empty..." Fluttershy turned her head, spotting the spare air tank. Great... Another journey... She began to attempt to force her tits in the direction that she had to head... But they swayed abruptly as she tried to force them.

CLANG!

Fluttershy JUMPED at the loud metallic clang. She sighed when she realized... It had only been her boobs knocking over the empty air tank... When they swayed, they must have off balanced the tank and it made it fall over

"Silly me..." she thought.

And yet... There was a sudden shiver that ran through her tits

"Nnh.. Wh-what..?"

Her breasts had started to grow. Fluttershy bit her lower lip... There must've still been a little air in the tank... And knocking it over must've loosened up the valve just a bit more, allowing more of the air to flow into her breasts...

She starting letting out feeble moans as her jugs squeaked together, accommodating the air...

"Just a bit larger, and they'll be perfect... Mm... Should probably get ready to turn it off..."

Fluttershy looked around for the air tank. Where was it..? It fell over... It should've been right next to her. Panic began to set in. It was obviously still filling her. It had to be nearby, but where? That... Was when she acknowledged the chill of something metal, and round, from underneath her breasts.

"Oh no..."

When the tank had fallen over, it had been covered by her growing breasts, and was now wedged underneath them, and the floor. She tried to move, as to get off the tank, and remove the hoses... But found that her chest was so much heavier! She tried again, getting frustrated, and also beginning to panic even more. She was stuck. And her breasts were inflating.

Fast.

She whimpered, the pressure in her chest continuing to intensify. She hated to acknowledge it, but her crotch was becoming damp... But now wasn't the time to think of that! She shut her eyes, and began to focus on her breathing.

"It's okay... The hoses will pop out eventually... And the air will leak out... And you'll be able to walk again... Don't stress..." she reassured herself.

As she thought this, she felt the touch of the wall against her nipples. She moaned suddenly at the feeling, the tips being pressed harder against the solid barrier... And the bizarre feeling of the hoses being pushed deeper into her breasts. Her face went red in embarrassment at the sensation... But... Now that her nipples were pressed against the wall... The hoses had been driven deep into her nipples, and pinned in place against the wall... The only way she'd stop expanding was when the tank ran out of air...

"Oh no..."

She writhed in pleasure as her tits swelled bigger, and bigger. The pressure continued to build more and more. Fluttershy's weak, hesitant groans, turned to passionate moaning. It was just... So big! She just couldn't help but enjoy the feeling, and to ride out the blissful sensation of sensitive tit flesh stretching, and tightening, squishing tightly against the walls of the room she was in...

Fluttershy reached her hand back, a sly grin on her face. She began rubbing the wet genitalia, her tongue lolling out of her mouth. She began panting heavily, dirty thoughts of her huge tits being used as an impromptu fuck toy for Purple, or the idea of her pink nipples being ruthlessly fucked and filled with cum... The idea of her tits being so full that they... pop... The idea scared her at first... But now it seemed so blissful! She was so close... A bit more growth and... And..!

Then the growth stopped. Her tits were a shade of bright red. The excessive air inside threatened to burst her... She could still hear the air hissing, yet she wasn't growing anymore.

"Ngh... N-no... Cmon.. Let me pop... Please..."

She shut her eyes in disappointment as her pleas went seemingly unheard... Until...

creeeaaak...

The tightness suddenly got worse, her eyes shooting open. They were starting to groan, as if they were still being filled... And then everything made sense... They were just so full that they couldn't fill anymore. The air was compacting together, tighter and tighter, filling out every available space inside... She was still inflating, but... With no more room to inflate...

"O-oh... Oh my goodness... I'm... I'm so close to popping! Oh, c-cmon... Let me pop... Please, I need to pop..!!"

The creaking from her breasts became louder and louder, a low, steady rumble began to intensify.

She heard the door creak open... Purple was home.

"Fluttersh...?"

"A-ah.. P-purple..! Nnngh!"

"Wh..." Purple couldn't tell what was happening... Until she did, her face going red at the sight.

"Ahhh! H-Happy birthd..dayYYYYAAAAAH!!!"

CREAAAAAAAAKK- BANG!

Fluttershy's tits gave way, the blast resonating through the house. She was sent flying her across the room, and into Purple, knocking her over, the two slamming against the wall, leaving the disoriented. Fluttershy blinked, shook her head. Once getting her bearings, she stared at Purple, blushing.

"H-hi.. H-honey..."

Purple was dumbfounded. "That... Was... a really good present."

Fluttershy giggled, rubbing her neck. "I... Could do it again..."

Purple smirked, her cock stiffening, Fluttershy's eyes widening

"I'd love that~"
