Rarity and Applejack Explore Inflation.

*Clink!

Rarity gave Applejack a seductive wink as they tilted their glasses drinking the sweet wine.

"Ya know Rare, I used to think you were plum crazy for likin bubble baths. I think I'll be keeping my trap shut about em now."

Rarity let out a gentle laugh. "That's certainly good to know. Next stop: the Ponyville spa."

"Ha! I don't think i'm quite ready for that just yet. The cowpony laughed.

"What a pity. I think you would rather enjoy it after the hard work you do at the farm."

Applejack fidgeted for a moment before in the bath. "Hey Rares, I'm feelin a might cold. Kick on the hot water will ya?"

The unicorn smiled a knowing smile and turned the handle with her magic. Water poured out of the faucet filling the tub.

Rarity watched as the bubbles above Applejack's belly started slowly pushing higher.

"Landsakes girl, this is exactly why I don't have one of these tubs, it takes forever to fill!"

Rarity just smiled as the water kept on flowing.

Applejack felt heavy, something felt like it was trying to pull her into the water. The cowpony glanced at the side of the tub and noticed the waterline hadn't moved upwards at all.

"Ya'll sure ya haven't pulled up the stopper by mistake?"

"Jackie, this is a two thousand bit jacuzzi, there's no stopper to pull."

Applejack thought about Rarity's words as she wrapped her forelegs around the edge of the tub. Looking down in front of her she noticed the bubbles were substantially higher there than anywhere in the tub. She used one of her hooves and separated the bubbles until she saw her orange belly, bloated and ballooning under the water.

"Lemme guess, potion in our wine?"

"Potion in your wine darling." Rarity corrected.

Rarity used her magic to turn both taps on to the highest setting. Water gushed out of the faucet and started filling the tub, and ostensibly, Applejack.

"Didn't know ya'll liked waterballoons." applejack teased.

"Variety is the spice of life my dear." Rarity said just as Applejack's belly broke the surface of the water. Rarity's hoof snaked its way under the water and started rubbing herself as Applejack's quivering and sloshing belly rose before her eyes.

"You see Jackie, this potion causes your body to absorb any liquids it comes into contact with, and we have been in contact with a lot of liquid."

Applejack watched as the water level went lower and lower, and her belly spread larger and wider as it encroached on the unused sections of the jacuzzi.

Rarity reached over with her other hoof and gently prodded her new waterballoon and watched as the water sloshed around inside the cowpony's massive belly. Despite the faucets being set to their maximum, the water level drained even faster as Applejack's bloated belly filled out the tub and started touching Rarity.

Rarity tsked as the last of the water drained leaving a massive pony water balloon and her sitting in an empty tub. The water still flowed out of the faucets, but it was a lost cause. Every once that poured in simply went straight to Applejack's gut.

"Well, I guess thats it for the bath." Rarity turned off the faucet and stared at her guest occupying the tub.

"I think it might be even better with water than with air, don't you agree darling?"

Applejack just smiled.

"Ah well, time for you to get out."

"And just how in Equestria am I sposed to do that?" Applejack asked sneering at the unicorn.

"Allow me." a magical aura engulfed Applejack as she slowly rose into the air, a giant quivering and wobbling waterballoon of a pony. She struggled to keep her lustful mind on the task at hand while maneuvering the massive orange balloon. With Applejack finally clear of the tub, she let the pony drop.

"Wooooah! Ooof!"

Applejack bounced and wobbled like a massive jello sculpture as the water inside shifted this way and that. After a few moments her body calmed enough for her to speak.

"Well? Are yall gonna have your fun so I can go back to normal?" Applejack asked.

"I do have an antidote if that's what you're asking, but I believe you're mistaken if you think this is as big as you're going to get."

Rarity grabbed her shower nozzle and disconnected the end using her magic so that it was now just a small hose. She was suddenly grateful she chose to have the workers put a drain in her bathroom as water started pouring out of the hose. She walked around to Applejack's dripping privates with the spewing hose.

"This shouldn't hurt I think darling"

Applejack audibly winced as Rarity smoothly pushed the end of the leaking hose into her plothole. A dull pressure rose inside the cowpony. More and more water pumped into Applejacks bowels filling her even further.

Rarity watched as the earth pony's body rounded out becoming spherical and pulling her hooves in.

"oh Rares, this feels amazin, but I need some real relief. Yer not gonna leave me like this are ya?"

Rarity shook her head. "Not a chance darling." Rarity walked to her bathroom cabinet and pulled out a box. She reached inside and produced a double sided dildo and a small vial. She carried both back to Applejack's head which took a little while since she had to walk around the cowpoy's massive body which now rose above her head like a dome.

"Bottoms up dear." the unicorn tipped the vial into Applejacks swollen and puffy mouth.

Now, once we finish with our... Pleasurable experience, i am told the water will gush right out and that is where this will come in."

Rarity held the dildo up for Applejack to see. The inside was hollow from one end to the other.

"This represents your chance to get a little payback. Let's see what you can do."

Rarity walked back around the now towering balloon that was her partner. She dragged her hoof around Applejack's moist lips eliciting a moan from the immobile mare.

"Don't worry dear, I'll take care of you."

Rarity slide the dildo inside her own marehood feeling her love tunnel clench around the intruding object.

"Hah... this... Is gonna be good."

Rarity took her time inserting the toy inside herself. She was mostly enjoying watching Applejack's body blimp further with massive quantities of water. She felt the massive dildo bottom out inside her and turned her attention to the other needy pony in the room.

She composed herself to the best of her ability and aimed her new toy protruding from her crotch right at applejack's marehood. She slowly inserted herself into her partner enjoying the delightful moans Applejack made as the pony's canal clenched around the dildo.

Rarity felt like she had pushed enough into her partner and started with a slow thrust. Applejack moaned in response and Rarity took this as a sign to keep going. She started bucking faster into her lover, but this was made all the more difficult by the fact that she had to stand on her hind legs with her front hooves pushing into Applejack's massive body.

"Thankfully, hah, my shop is, unnnn, built for large... Activities." Rarity moaned out between thrusts. With each buck, water sloshed inside the giant water filled pony creating a wave of sorts. Rarity carefully thrusted with the waves increasing both of their pleasure. Applejack's moaning started increasing in volume and the massive sphere that was her body rumbled dangerously preparing to expel it's payload. Rarity could tell the mare didn't have long before she would climax and start pumping water into her. Using her magic she reached down and yanked the hose out of applejacks plothole letting it fall to the floor and spill out.

Rarity continued bucking against her lover with reckless abandon eager to satisfy herself as well until she heard Applejack gasp in delight.

Rarity's eyes widened as a pressure in her marehood made itself known. In one massive gush, the water flowed from Applejack, through the dildo, and into her own womb flooding it as she continued bucking against her lover, eager to cum before she was made immobile.

Another burst of water caused Rarity's belly to surge outward as if she were pregnant and due to give birth at any moment. She continued pounding into Applejack as she saw the muscles in the massive mare's body contract again preparing another large payload of water.

Rarity slammed into Applejack once more in ecstasy as she fell off the precipice of pleasure.

Another torrent of water filled Rarity's canal as she bucked instinctively riding out her orgasm. Her gut sloshing and wobbling filled out even further threatening to push them apart.

One more blast of water flowed from Applejack to Rarity, pushing the white mare's belly past the size of a weather balloon. The unicorn fell backwards onto the floor pulling the dildo out along with her. Both mares lay panting on the floor and rubbing their swollen bellies as gallons of water poured out in bursts onto the floor and down the drain.

~

a few minutes had passed and both ponies had finally recovered as the last bit of water splashed out of their sopping wet marehoods.

"Applejack, I shudder to think of what the water bill will be this month."

"Totally worth it, Rares."
