You arrived at school, early as always and pushed your way through the rabble of people getting off the school bus and headed towards the sixth form block. Outside of the sixth form block was standing Claire Simpson, on her own as she had no friends. You felt sorry for her as the reason no-one like her was simply because she was a bit skinny and flat chested, which was a shame, as you thought she was quite gorgeous. She was petite, with slender frame and light brown hair, perfectly straight and parted in the middle, about shoulder length. You usually spoke to her to cheer her up and decided that would be the case today, as she looked miserable.
"Hi" you said, as you know no better way to start a conversation "What's up?"
"Everyone's blanked me", she replied "I wish had a fuller figure and big breasts, I only want to be noticed".
A solitary tear rolled down her cheek, you wiped it off. You wished there was some way to help her, but of course that's impossible.
Then the bell rang and you both went to lesson, you never saw her after that, but you thought long and hard about what she'd said.
After school you went to the local October fun fair, still thinking about it. There was a man giving out balloons filled with helium, You watched as the balloons were inflated stretching and rising. Then, you had a brainwave. After the fair had ended, you went to find the man and asked if he had any spare helum, he did, but you had to fork out a tenner for it, however you felt it was worth it.
The next day, at school you told Claire to make sure her folks were out so you could come round with a suprise for her. "I suppose" she said, "What sort of surprise is it?" Trying to remain as cryptic as possible, you replied "It's the present of your dreams, you know, that thing you've always wanted". She seemed sceptical but assured you that her folks would be out.
You arrived later that evening with the helium. Claire answered the door, looking lke such a hottie in her pajamas. "My Dad's still at work and Mum's at a PTA meeting, we're alone till midnight" she said. She then stared at the helium with a worried look in her eyes. "Is that it?" she said. "Yep" you said, as you followed her up into her room. Once there you asked her to pull her pajama bottoms down a bit. She obliged, showing you just the top of her bare arse. You told her that she would enjoy the result and may get a bit of a kick out of the first bit too. "Why, what are you going to do?" she asked nervously. "Inflate you" you replied, "to give you a fuller figure" With that you gently but firmly put the end of the hose in her arse, and gently patted it. "Ready?" you asked. "I'll try anything" she said and pulled her bottoms back up. You went to the helum and turned the valve on a bit. There was a hissing sound, a bit like a balloon inflating, followed by a bubbling sound from inside Claire. Then Claire's bum began to bulge slightly, becoming more pert and pushing outwards and upwards. Claire's eyes widened and she tentatively felt her expanding bottom. You gave it a gentle slap. " That's more like it" you said. By now her bum was as big as two ballons and stretching her pajamas, she was having to pull on the top of her pajama bottoms to keep them from getting pulled down. Then her belly began to bloat and swelled slightly. "This isn't exactly the kind of figure I wanted" said Claire, rubbing her bulging stomach and then grasping her voluptuos behind with both hands, "You're just blowing me up like a balloon". Her midriff continued to blow out as she waited for an answer. There was a stretching sound as her stomach began to strech her pajamas and rise, you said nothing, you had never seen anything so sexy in your life.
By now Claire's arse was well pumped up, like two beachballs wobbling beneath her pajamas. Her belly was also full of the gas, and she was still ballooning. A smile of pleasure spread across Claire's face.
"I never thought that being pumped up would feel so nice" she said. You went and patted her bum, it was bouncy with the gas.
"Or so sexy" you replied. Claire's inflated bum and stomach were now as big as over inflated beachballs, and her pajamas were really starting to stretch. Then her breasts began to expand, and rose because of the helium, to about a DD cup. Claire giggled and rubbed them. "I love this" she said, "give me more". You obliged and turned up the pressure. Her breasts bulged up to the size of footballs, then beachballs and her belly was the size of one of those huge balls that physiotherapists use. Her bum was the size of two!
Then Claire began to rise off the floor, her giggling stopped.
"Am I going to float away?" she asked, "or worse, I could explode, go bang, really blow up!!" Her breasts, belly and bottom countinued to swell up, stretching her pajamas. The rest of her body and legs and arms began to inflate now and she was firm because of the pressure. She was floating about a foot from the floor, and had pumped up to such a size that she took up most of the small room. Her breasts were now about 3 feet wide each and the rest of her body was almost spherical.
"I guess we could call you compressed air Claire now" you retorted
"Just shut up and get me down!" she shouted, she was getting panicky. You tried to turn the valve off, but it was stuck! She continued to inflate, getting bigger and bigger. Her legs and arms were outstretched and inflated and her stomach was bulging forwards, her bum was still swelling and blowing up and her breasts were still billowing up with all the gas. Her body began rumbling.
"Too... much... gas!" she just managed to scream, "I'm gonna burst, gonna blow!" Then you heard a squeaky farting noise as some gas began to escape through Claire's arse and nipples, accompanied by a pained stretching noise.
"This is it" she just managed to say "I'm going to blow!".She closed her eyes tight and screwed her face up, her eyes then suddenly widened, "nnnngh!".
Next thing there was a tremendous deep BOOM!! and you were thrown back off your feet by a blast of hot air. The glass in the window was blown out and most of the stuff in the room was blown back. The smoke cleared and you looked around. It looked like a bomb had hit and shreds of clothing were scattered around the room. The helium tank was lying on the floor still hissing with helium and Claire's slippers were standing in tatters in the midddle of the room. You gasped in astonishment at what you had done. Then you heard the front door open and a shout.
"Claire, darling, we're back"!
