December Story Poll: Writing.com Shelly and Elizabeth (Patreon)

Shelly's eyes widened as she felt the water pressure in her ass surge. Her ballooning belly swelled up even faster getting bigger and bigger lifting her higher off the ground. Shelly let out a loud moan "Oh God Yes! More, more! It feels so good, I want to keep growing and growing Unnngggg I don't ever want to stop!"

Shelly heard a moan in the background she craned her head back to see who it was. Her cousin Elizabeth was sitting next to the valve, her back resting on the house. She was rubbing her pussy and kneading her very swollen belly. "Oh, you have no idea how hot that sounded,” Elizabeth cooed as she played with herself. “I was getting turned on watching your big, sexy stomach swell.” 

She grinned slyly “I wanted to see you grow faster,” Elizabeth said as she cracked her knuckles “so I did This!" Elizabeth gave the valve another twist. "When I heard you say those words, II nearly came right there." Elizabeth started rubbing her clit hard " hhhhnnnnn, grow for me babe, grow."

"Yes, Yes, YES!!" Shelly shouted as she felt the water flowing into her faster. "I'm your big sexy swelling plaything, just keep making me bigger a-and Bigger a-a-annND" Shelly could feel her orgasm coming. 

She started bucking her hips, her humping caused her to bounce slightly. Her swollen tummy was now big enough to lift her off the ground. "BIGGER!!!!" Shelly screamed as the best orgasm of her life racked her bloated body. The hose in her ass came loose and fell to the ground spurting water still.

Shelly looked back to see if her not as filled, but still, sexy cousin was enjoying the show. However, she wasn't there "Elizabeth?" Shelly continued to look around the yard "Elizabeth!?" shouted a little louder this time.

"Be there in a minute!" she shouted back.

Shelly peered towards the sound of Elizabeth’s voice "what's she doing in the tool shed?" Shelly looked down at herself and sighed "it was fun while it lasted" she rubbed her mountainous belly. Shocks of pleasure ran through her body "Jesus! it's so sensitive I could get off by just rubbing my stomach!" Shelly said impressed. She was getting hot again. 

Shelly cupped her breasts in her hands. "It's to bad you two couldn't have gotten any bigger" she started kneading her boobs slowly "I bet it would have been a lot more fun with you girls along for the ride." She tweaked her nipple slightly and let out a slight moan.

"I'm glad you feel that way" Elizabeth stated

"You missed me cumming" Shelly stated in a very sultry voice. She looked up at her cousin Elizabeth was holding three more hoses and two y-splitters. "Where did you get all that!?" Shelly exclaimed excitedly while staring at the three hoses hungrily.

"Well I only half missed it, and I most definitely heard it" Elizabeth shrugged the hoses upon her shoulder. "Anyway my dad is a bit of a lawn psycho, he has all this gear for watering the grass,” Shelly pointed at a large tank “he even had a bigger water pump installed to make sure it never loses pressure." Elizabeth smirked at the last comment "Now what am I going to do with these?" 

--------------------------------------------------------------------------------------------------------------------------

"I can't deny my dear sweet cousin what she wants," Elizabeth said smiling walking towards the water valve.

"Four hoses! all in me?" Shelly got horny again just thinking of that idea "But why aren't you joining in the fun?, I mean you look so sexy with that big belly you would look much hotter growing bigger with me" Shelly quizzed daydreaming about that Idea.

"I will in a little while" Elizabeth responded finishing hooking up the hoses and walked towards Shelly the ends in hand "but first I want to see how sexy you'll look getting filled from here" Elizabeth shoved one of the hoses into Shelly's ass Shelly moaned loudly "and here" Elizabeth inserted another hose in Shelly's pussy and walked around to Shelly's face and pressed the last two against her nipples "hold on tight to these" Elizabeth instructed and made her way back to the valve "Ready?".

"Hurry and turn it I can't to see how big I'll GGEETT!" Shelly shirked as Elizabeth gave the valve a vicious twist open Shelly felt the torrent of water entering her from the spewing mouths of four hoses. Her massive belly surged again and Shelly moaned in pleasure from the intensified feeling of her stomach swelling twice as fast. 

Her breasts billowed out in her hands and her hands slipped from the hoses. Shelly's heart skipped a beat as she watched the fall slightly limp but to her amazement still were attached to her boobs she reached out with her hands to feel what was going on her nipples had swollen around the ends of the hoses and were holding them in place. 

"Oh YES" Shelly moaned "my nipples swelling over the hose ends it is a sign, even my body wants to keep blowing itself up bigger and bigger, swelling and swelling larger." Shelly began kneading and shaking her swelling zeppelin shaped tits bucking her body doing anything she could to make sure those hoses wouldn't come loose. 

Her tits had already gotten massive while they weren't as swollen on the round as her massive, still setting the pace belly, they had almost reached the ground. No easy task as her blimping tummy was already raising her 7 feet off the ground but her juggs were big inflating plump zeppelins and Shelly wanted more. 

She looked back and down now on her cousin who was busy playing with her distended belly, fingering herself and moaning loudly "Elizabeth?" Shelly called to her.

"What?" Elizabeth asked between moans.

"How far is the valve open?" Shelly asked praying it wasn't all the way.

"Only around a quarter turn, I didn't want to go too overboard with it" Elizabeth responded.

Shelly's heart leaped for joy "Open it up more need more I want to swell faster and get bigger I need more!"

Elizabeth looked at Shelly's massive still growing flesh balloons and then at the valve she placed her hand on it "To turn or not to turn? that is the question." 

Elizabeth looked back at Shelly "you got a lotta growing left to do my beautiful swollen sex balloon" and she turned the valve open to the halfway point.

Shelly's eyes opened wide as the flow increased in intensity every time the pressure increased it was like being born anew "yes, yes, yes, yes, yes, YES!" Shelly could feel her tits and belly blowing up faster, the ground continued to get further away from her she could feel another orgasm coming a big one. 

Shelly's body contorted and she started furiously kneading her now 9 feet long 6 feet wide blimps using her knees and hips to agitate and rock her water bloated 15 feet wide 10 feet high belly back and forth. Feeling the hoses rock back and forth in her holes she imagined they were cocks fucking her ass, pussy, and plump billowing fatter and fatter nipples.

Elizabeth realized what was happening and quickly as she could anyway ran to the front of Shelly she wanted to help with this one Elizabeth looked at Shelly's football-sized nipples swaying no far off the ground. 

Elizabeth Positioned herself on the ground under the nipples she warped both hands around one and began to lick it and work it with her hands the other nipple she wrapped her legs around it, pulled it to her pussy and began to grind against it. 

The nipple bumps felt wonderful rubbing up and down her pussy and stimulating her swollen clit Elizabeth began grinding harder trying to work her self to orgasm along with Shelly she could feel the nipples swelling bigger and bigger. 

With each passing moment feeling them swelling was turning her on even more than watching Shelly's boobs and belly stretch wider and wider and watch her cousin stroke, fondle, and hump against her ballooning breasts and tummy as they push her higher and higher into the air.

Then in Elizabeth's mind, Shelly vanished and instead she was looking at herself. Her belly still swollen the hoses that were in Shelly now lying on the ground came to life and started slithering towards her one circled back of her and the other 3 to the front. 

The one in back worked it's way up her leg and pushed its way hard into her ass Elizabeth moaned the other three struck out two attaching themselves to her nipples, the final one working its way into her tight wet pussy. Off in the distance, she could see the valve turn itself open and the hoses swelled 6 times their normal size as the flood of water forced it's way down the hoses "Yes!" Elizabeth screamed in both her sexual daydream and out loud. 

The swell of the hoses was getting closer to her "I want it...I want it" the water drew closer "I need it" outside her sexy dream she started thrashing against Shelly's now basketball-sized nipple letting go of it she started groping her beanbag chair belly feeling the water slosh inside her swollen sexy stomach she could feel her orgasm on the edge. 

"I Need To...." in her dream the water hit her and she ballooned easily three sizes larger than Shelly's current size, Elizabeth head arched back and she shrieked "GROW!" as her orgasm hit her she continued bucking and thrashing orgasm subsided she lay there panting.

******************************************************************

Shelly watched Elizabeth run or kinda anyway to the front of her and lay down on the ground she was going to ask what she was doing but Shelly could feel the orgasm brewing deep in her loins she wanted this one to be better than the last one. So she was doing all she could to make that happen rubbing and stroking and squishing her inflating zeppelins. 

As they kept getting bigger and bigger, fatter and fatter her legs working her massive stomach. Shelly felt a massive surge of pleasure coming from her tits "Oh God she playing with my nipples Fuck Yes! work those bloated sex nobs" Shelly reached back and grabbed the hose sticking out of her ass and began to work it in and out the changing water pressure made it feel like she was being fucked by a massive dick "oh fuck." 

Shelly moaned working the hose faster "F-Fuck, oh, oh god, oh fuck yes, more...More!" she could feel the pressure wrapped around her right nipple increase and the pace of the grinding against it speed up "Elizabeth is getting off grinding against my nipple that is so fucking hot" Shelly pictured Elizabeth grinding against her nipple in her mind and that was all she need her climax peaked. 

Shelly's head whipped back mouth open letting out a low guttural sound and her body started twisting and contorting, muscles tensing for what seemed like an eternity and then her body finally went limp.

Elizabeth crawled out from under Shelly's bloated bosom and looked up panting "So want a break before round two?"

Shelly looked down at her cousin she could still feel the water rushing into her gargantuan body. Her belly was pushing past the 20-foot mark, her breasts not far behind. "No, I want to keep going please" she pleaded to Elizabeth.

Elizabeth looked up at Shelly and smiled. "Naughty girl, taking all the fun for herself," Elizabeth said as she walked back towards the nozzle. "Onward and upward!" Elizabeth twisted the valve all the way open.

Shelly squealed in delight as she felt the pressure of the water flowing into her body increase. Her belly jumped to a larger size as it continued to be pumped fuller and fuller of water. "Nnnnnggghhhh grow fatter, and fatter and fatter! I'm getting so fucking BIG! It's not enough. Bigger, I want to be huge, bigger than my house!" she moaned as her tits and belly continued to puff up, swelling past the 30-foot mark.

She looked back to see that she was the same height as the peak of her roof the sight of this made her cum again. "Ooohhhhh more, more, more... oh god YES!" Shelly continued her chant as her huge bloated jugs and stomach hit 40 feet each. 

Gallon after gallon water-filled Shelly's tits bigger, and bigger, and bigger, made her belly swell fatter and rounder and sexier with each passing moment "Yes!" she moaned "Just keep pumping my bloated sex pillows up, and up, and up!"

Shelly thrust her hips against her giant stomach relishing the sensations that rippled through her body "I just keep getting bigger and sexier I want to be huge as big as a mountain. No, bigger! I'll keep swelling and swelling til' I'm the size of the planet!" In her mind, she pictured her self as she swelled and grew until she was bigger than the earth and she came again.

Shelly's tits and belly pressed on to the 50-foot mark and then the 55-foot mark. Suddenly, she felt the most horrible sensation Shelly had ever experienced in her life. She felt the hoses in her ass and pussy pop out and fall to the ground. Shelly shrieked in desperation "NOOO I'm not big enough! Bigger, I want to get bigger!"

She could feel the water still filling into her tits and focused on that. "Alright forget my belly," she moaned "Ohhh yes! Just keep growing my big beautiful boobies. I'll have the biggest, sexiest tits ever! So big, I'll tit fuck everyone" Shelly began rubbing her tits "As long as you point down, you just keep getting bigger and fatter and rounder. Don't you ever stop fucking growing you big sexy mountains."
