Emma's Detention

Boredom, that’s what Emma had suffered for the last 10 minutes, and ten minutes was enough for her. She was a blonde haired, curvy girl with C cups and a large ass. She was hounded by most of the boys in college as the hottest girl but Emma was already taken, off limits to all but her bf Max and she loved it, teasing all the boys and some girls too.

Emma was sat in the science room, she’d been given detention for failing to complete a simple lab prac “hardly fair” she thought. As she gazed around the room her eyes set on the helium tank. It was mainly used to show the effects of helium on the vocal cords.

Emma being herself wanted to try it again and as the teacher hadn’t even turned up the detention she thought she could have free reign on the lab equipment. Emma got up and swung her large ass over to the tank, she was dressed in a tight t-shirt and leggings that her ass was snuggly packed into.

Giggling as she placed her lips on the nozzle of the tank, she gave handle a turn, little did Emma know that the tank was highly pressurized and was only meant to be used with balloons and once activated it would not shut off until it ran out or the balloon full, in this case Emma.     

Emma’s eyes shot open as she felt the blast of helium roll down her throat, she suddenly started to feel her leggings strain and tighten over her ass, as she used her hands to investigate this she found her butt far too quickly and found there was more of it. As she went to pull away from the tank she slipped back landing on her enhanced rear tank still firmly placed in her mouth filling her with helium.

Emma gave a groan as she discovered that she was inflating and fast, Her flat stomach pushed out against her t-shirt and displayed her navel piercing, As this happened Emma’s hands shot to her now rounding stomach and found she liked it. Her butt still pushed out against her leggings, ripping them and displaying Emma’s very tight thong.

As Emma’s helium intake increased so did her mass, her C cups had joined the expansion and Emma cooed even more. Her whole body swelled and plumped up as the lab was filled with sounds of the tank, Emma’s moans and the rubber groaning sound from her body.

“Mmmmm Max is gonna have plenty to play with at the rate I’m going” Emma moaned as her ass fought its way to freedom from her now painfully tight leggings as her thong clung on for dear life.

Emma’s t-shirt gave up the fight too as her breasts and belly found their way to beach ball size, it was at this time Emma took off and found her mouth easing away from the nozzle.

“No” she groaned

“You’re not getting away from me that easily!” she shouted biting down on the tanks nozzle anchoring herself to her precious source of expansion.

Her body groaned as she swelled, more helium meant more growth. She was in bliss evident by her displayed erect nipples which where themselves swelling with helium and her dripping snatch which was growing thicker and puffy. She was so turned on by the simple fact that there was so much of her and the lust she had for wanting more.

Finally her bra and thong gave up the struggle blowing off bloated frame, her limps had shrunk into her mass and she was floating just shy of the ceiling when the tank shut off.

“What? Empty? But I want more!” Emma exclaimed

“I want to be big enough to fill this room” She whined

As she floated round the class from she made efforts to push herself down to the ground acching to tend to her dripping pussy and to get more helium in her finally on of her attempts saw success and she got both her desires by landing on a spare helium tank which in doing so turned on, throwing Emma in to a mindless orgasm. The swelling began anew with a new helium source Emma grew and grew swelling ever larger.

“Man who thought detention could be so fun” Emma said with a smirk as her growth continued uncontested until the sound for the start of class.
