"Water-Tight" Butt Expansion Quickie

[hmmm!]

This is a fun little diddy that Soylentorange and I put together. He wrote the story and I drew the picture.

I'll attach the picture here and the story will be in my next post.

Enjoy.

[hmmm!]

Dorothy stepped up to the waiting platform, almost entirely dry again. She'd been at the waterpark for hours already, but the seemingly interminable line had taken so long to get to the top she'd drip-dried off during all the waiting. But for the chance to slide down the biggest waterslide in the *world*, she'd wait as long as it took.
She could see it spiraling down the tower, around and around, then snaking its way all the way across the park. It was so far away, the attendant at the bottom had to use semaphore flags and binoculars to signal when it was clear for the next person to go. Dorothy waited, and waited, and waited, bouncing from foot to foot. She'd always loved waterslides- the fast ones, the steep ones, the twisty ones.

Finally, the attendant put his binoculars down and waved dorothy into the starting pit. The large reservoir next to the slide slowly filled with water as she lowered herself in- sixty gallons, eighty gallons, one hundred gallons- she could hardly take her eyes off it. Dorothy backed up as close to the output grate as she could- when all that water came out, she wanted to be sure it all went to the right place.

"Face forward," The attendant said, and Dorothy looked down the dark tube as it faded into darkness about twenty feet down. Dorothy's heart raced, waiting for the moment, clapping her hands in the water to get herself psyched up. With a tremedous *woooosh*, Dorothy was rocketed forward, pushed from her sitting position into a laying-down one, the cushion of water cradling her head and shoulders as it bore her down the first few sharp turns.
Dorothy, having been down more than a few waterslides in her life, began showing off. No one was there to see it, obviously, but it was just as well; Dorothy had been banned from a few parks for "goofing off" on their slides. But since this one was covered most of the way down, Dorothy had the time and the space to pull a few maneuvers. First she leaned up a bit, pulling her arms from her sides and flattening her hands up and down on the slick blue composite. This slowed her down, causing more water to collect against her back. Then she snapped her arms down and pulled her knees to her chest, spinning on her back in the stream and ending up turning completely around, now going head-first and backwards down the waterslide. It was an exhilirating thrill, and it only emboldened Dorothy further.

Dorothy took a breath and flipped onto her stomach with a quick jerk of her shoulders. The water rushed past her face as dorothy brought her arms under her, pushing back onto all fours, her forearms and shins acting like a set of ice skates on the slippery composite. She grinned as she managed to steady herself, but the grin quickly faded when a light appeared at the end of the next section- she was coming out into one of the uncovered sections. Dorothy kept her balance on all fours, waiting for the right moment. It was too low of a ceiling to sit back in, and too little time to turn around. But if she timed it right...
As soon as her head neared the end of the covered section, she pushed off her forearms and slid her legs forward, flipping backwards and landing on her back in the "allowed" position, just in time to pass one of the posted attendants. Dorothy watched the line of swimmers on the catwalk above her and waved- she'd seen countless other riders pass by while she had been waiting in line as well. She also knew that there were a series of severe turns coming up, and decided she'd show off as best she could while staying on her back. She started swishing side to side in the water, using little more than her feet, her hips, and her shoulders to alter the flow of water around her, pushing from one side to the other, gaining momentum each time. She swung to the far side of the tube as she approached the first sharp turn, then swung hard towards the banked outside edge of the tube. Once she reached the apex of her turn, she pushed off hard with her shoulders and elbow, decanting entirely from the side and doing a complete corkscrew in the air before landing with a splash on her back again, eliciting cheers from the watchers in line.

She grinned, but couldn't help but feel a little sting in her behind, like she'd come down on it too hard. She didn't see why that might be- she'd practiced the move a hundred times before, and she'd kept her back totally straight like she ought to- but she dismissed it. maybe there was a lip on one of the tube sections, that's all. Dorothy slid into another covered section, and was thankful for the darkness, because her suit was beginning to get uncomfortably tight. It wasn't a terribly uncommon occurrance- water wedgies were a given, especially on the faster slides- but still, fixing one mid-run wasn't an easy task. She turned on her side, hooking one arm to drag on the water and slow her descent while she tried to fix her one-piece swimsuit. Losing so much speed would curtail her tricks, but she certainly didn't want to come out in the next uncovered section, well, uncovered.

When she reached back, however, instead of finding the bottom of her lycra suit, all she felt was the slick, rubbery resistance of her own flesh. Dorothy quickly flopped to her other side, and felt that end as well, much more junk than she'd ever had in her trunk. Dorothy's brow furrowed, but in the dark, wet tunnel she couldn't see anything- only feel. And feel she did, as her rear seemed to be positively swelling with each passing second. Her feet, normally crossed over one another and pointed to reduce drag, began slowly slipping off of each other as the swelling seemed to radiate down to her knees, her thighs growing so much thicker that the wall of meat couldn't be overcome, her feet barely able to touch toes, much less cross. With a sound like a suction cup unsticking, the hollow in the small of her back lifted off the floor of the tube, the twin globes of her rear protruding too much to allow her to lay flat.

She groped around in the dark, trying to feel some reason why she was expanding, to find some kind of insect stinger or syringe needle, anything to explain why everything from her knees to her waist was slowly but relentlessly growing. But all she felt was her own skin, warm despite the cold water and so slick to the touch it slipped out of her hands and between her fingers when she tried to squeeze it, searching for any sort of symptom that would make sense.

Dorothy put her hands out, but her trimmed nails just slid along the walls. She tried to open her legs and brace her feet, but with the water-tight seal her swollen legs were making and the already-constricting fit of her swimsuit, that was quickly revealed to be a very bad idea indeed. She clamped her legs shut, seeing spots from the brief yet intense sensation. Panic began to creep around the edges of her mind- of all the tricks she'd taught herself in the thousands of times she'd been down a waterslide, how to stop had never been among them. The roof, the walls, the floor, everything was made to be nearly frictionless. What made for a great-quality waterslide was now keeping her from getting any kind of help.

Dorothy struggled to keep her head up- the growing mass of slick flesh had raised her pelvis up enough that her shoulders were planted firmly on the bottom of the tube. Her thighs had gotten so thick her knees had to bend to keep her feet on the ground. "Maybe if I put my feet against the roof and push my back against the floor, I can stop", Dorothy thought. She bent her legs as best she could, her calves running into the bottom of her thighs rather quickly.
"Okay... here goes..." Dorothy said. "Hupp-aaah!"

Dorothy's back slapped the floor as her hips rotated, the bulk of her enormous bottom now facing down the tube instead of propping Dorothy up off the floor. The plan was for her to kick her feet against the roof hard enough to press her back into the floor hard enough to not allow water underneath, thus stopping her descent, but the force with which bending her knees to her chest had caused her swimsuit to compress against her, especially with the added distraction of her bulbous cheeks creating basically a high-pressure water funnel, it was all she could do to clamp her arms around the backs of her knees and hold on for dear life. So it was in this state that Dorothy emerged back into another uncovered section, shooting over the lazy river.
"Haahhh... he-heellllp!" She managed to cry out, now travelling butt-first instead of feet-first down the slide. "Hell-unnh-helllp meeee!"

Dorothy felt a growing pressure in her chest, and she grabbed on tighter as she tried to hold her wet hands together. But the inexorable force of her growing thighs slid her hands apart from each other, inch by excruciating inch, until finally the little ball of Dorothy exploded out, her legs flopping in front of her while her arms fell to her sides. Dorothy tried to turn to her side again, but her hips had reached such an insane girth that turning to the side put her on a wet, fleshy fulcrum, unable to even keep her balance before the ripples of flesh slid one way or the other and made her fall on her back again. The slide began turning violently again, and the higher, dryer parts of the tunnel squeaked in protest as the far ends of her thighs streaked against the high sides of the turns, the flesh catching momentarily as she shot down the increasingly claustraphobic tube. Sensation was all there was now, the noise of rushing water and the sensation of wet, slippery flesh and slick composite, or of flesh rubbing against itself like the way her legs mashed into one another from her waist to her calves every time she bent her knees. It was as though the tube was shrinking, the way her rear felt more and more of the tube with every passing second, her swimsuit an academic proposition of a tiny stripe of navy lycra disappearing in the small of her back and reappearing under her stomach. She began trying to slow her descent again, the motions different but no less futile. As she rocked back and forth on the fulcrum of her distended rear, thrashing about as only the truly desperate can, she took a turn and went up on her side, a brief feeling of weightlessness as she reached complete neutral motion on the fulcrum of her rear before the curving of the tube dropped Dorothy onto her stomach. Her legs went wide, pushed apart by the water she was rushing into as well as the gargantuan bum forcing her legs apart with layers upon layers of wet, slippery meat weighing down on them. Dorothy cried out in pleasure as the tightness of her bathing suit and the rushing of the water all but tortured her with incessant sensation.

"Huhh... Hahhh..." Her pants echoed down the tube as she clawed futilley at the ground, trying to push up against the masssive,bloated weight of her backside. She managed to bend at the waist slightly, distressed at how short a distance it was from her bottom to the roof of the tube. She tried rocking back and forth, but aside from squeaking a few patches of her skin past the top of the tube, nothing was slowing her down. Sunlight illuminated her once more, and Dorothy briefly felt two pairs of hands, one on each cheek, try to stop her and get little more than a fleeting handful of slick flesh for their troubles. As her gigantic rump pulled her down the chute like a big fleshy anchor, Dorothy had the terrible thought of the growth continuing until she stuck inside the tube. What if it grew watertight? Would they be able to shut the water off in time? Would it drain? How high would the water level go? As her massive thighs squeaked on either side of her, Dorothy knew she had to stop herself before the final covered section, lest she drown imprisoned by her own flesh. Dorothy shook back and forth violently, trying to get any kind of leverage she could, her stuggles sending ripples through her buttocks so violent that droplets of water flung off them when they reached their terminus. Finally, another series of sharp turns began, and Dorothy pushed with both hands against the inside wall of each turn, sending her further and further up each successive slope until she was nearly parallel to the walls, where she pushed off as hard as she could, finally overcoming the resistance of the enormous sacks of meat dragging her down the slide and landing on her back again, seeing stars briefly as her head hit the ground. Dorothy had no time to celebrate, though- the dark void of the final enclosed section was fast approaching. With every ounce of strength she had left in her, Dorothy launched off her back, wrapping her hands around the top lip of the tube, her arms jerking straight as her enormous rear end was suddenly forced to stop. Dorothy gritted her teeth as her titanic bottom pulled against her, carried by the water, even as it still grew. She felt the water pooling against her bottom, only trickling past the sides of her enormous bum. Soon even those trickles stopped, and Dorothy felt the water level rising behind her, her increasingly-giant butt and thighs continuing the slow outward march. Dorothy felt the water creep up to the small of her back, and was thankful she was able to turn face-up; with so few handholds available she was certain she'd have a harder time keeping her head above water otherwise.

"Miss! Miss!" One of the attendants yelled, running up to her. "What are you doing?"
"I'm stuck!" She wailed, holding on for dear life.
The water continued to build, flowing up her back as it tried in vain to escape around the bottom. With a final slurping, bubbling noise, Dorothy's butt filled the entire waterslide tube, a watertight seal of slick, slippery flesh. Water began to overflow the sides of the open part of the tube, a sheet of water steadily cascading over the sides. Dorothy slackened her grip for a moment, and realized the pressure of the water was maintaining the watertight seal- so long as nothing changed, she was stuck fast. Dorothy released her grip and took a deep breath, her torso floating in the pool of water behind her while her butt and thighs dried out.
"Looks like it's the lazy river for me from here on out..." She thought to herself.

*high five*

High quality stuff, men.

My only complaint are the huuuuuuuuuuuuge heels she's got there.

[silverbolt2012]

Wow.

I can honestly say you two are one of the best partnerships in the expansion community right now. ^_^

Great pic. Great story to go with it! =D

[Nihtgenga]

Damn good stuff there, dudes.

[Kenster102.5]

You should maybe do another story like this, really great to read, very vivid.

Are the other great patnerships? Usually in this business it's mostly solo acts. :P
