Alexis awoke the next day to the feeling of her phone buzzing on her ass, somehow having slipped down it during the night. “Oh… oh no…” she said, feeling it vibrate on her soft flesh, some 5 feet away. She leaned, her phone barely out of reach. She could almost get to it if she really stretched, but she couldn’t quite reach it.
“Damnit!” she yelled, punching her ass, feeling her almost entire arm enter into her soft, warm flesh with very little resistance. This gave her an idea. “What if I… pressed…down?” she thought.
She put all of her strength into pressing her hands into her soft ass. It didn’t take much strength to get it to squish, given the absolutely obscene amount of smooth fat within. Her hands sunk in over a foot, but she was successful! Her phone slipped down, between her hands. Still pressing down with one hand, she grabbed her phone with the other, and then brought her torso back up, feeling her flesh rebound and shake for a few seconds. She unlocked her phone, the screen telling her it was almost 9am. She saw a message from Ellie.
E: hey school cancelled. gas leak or somethin. txt back when u see this
And so, Alexis did.
A: heyyy
E: morning!! mind getting measured again? for science?
A: hail science!
E: alright :) be out in a sec
A: ok!
Alexis looked over, peering over her mountainous body to Ellie’s door. Alexis got up, feeling taller than she was even yesterday. “Oh, oh no…” she said, realizing she was, once again, even larger than the day before. She texted Ellie, asking for the measuring tape again.
A: hey u still got that tape right?
E: yea y
A: need to find height
E: ok
Ellie brought out the tape, mouth opening when she saw Alexis. She was absolutely huge! She must have gained another 10 feet in height, her hooves now taller than Ellie was by themselves!
E: hey uh how am i gonna get this to u
A: uhh one sec
Alexis then tossed herself back down, her ass and thighs jiggling like mad. Ellie crawled up her friend’s mountainous rear again, measuring now an astonishing almost 60 feet from edge to torso! She guessed she was almost 30 feet up, sitting there on her friend’s ass. She crawled back down, this time taking the long way down her friend’s leg. Alexis did the best to hold the tape steady at her end, leaning her elbow into her soft flesh as she watched Ellie slowly traverse down her leg, reaching her foot some 4 minutes later. “Ok… damn… over 40 feet long,” Ellie said, astonished.
E: [picture]
A: 516 inches!! what!!
E: I KNOW!! :O
Alexis watched her friend hop off, some 43 feet away. Once Ellie was safely off of and away from her, she got up and thundered over to the scale, lower body jiggling and swaying while she walked. Ellie followed her, watching from far below as her udder brushed the ground, her ass shaking immensely above her. “Oh, Alexis… at least you seem to like it…”
Alexis stepped onto the scale, and Ellie sent her another photo of the result: 246.53 tons! She’d gained almost 15 tons in her sleep, coming in at a mindboggling 493,060 lbs!
E: [picture]
A: :0
A: yet im STILL HUNGRY >:0
But Ellie had a theory about this. If it was the water that triggered her change in the first place, maybe she should try drinking only soda? She had given her tap water in the bottle, so it was worth a try. The tap was filtered, yes, but still locally sourced. Ellie suggested the soda to her.
E: hey i have an idea
A: what is it
E: ok yknow how the water was what caused u to change??
A: yeahh
E: wellll what if u just drank like coke or something today, not water?
A: suuure? for science?
E: for science!
So, Ellie went back inside. Alexis wondered around, unsettled by her even more massive rear. As she walked, she felt her phone vibrate.
E: hey stop that! ur making the house shake!
A: sorry!!! im just walking!
E: holy shit u do weigh a ton then
Ellie then returned with a twelve pack of coca cola with a strap on it, bracing herself for when Alexis flopped eagerly down again. “Y’know, I’m really starting to like this body…” Alexis thought to herself as she slowly bounced up and down on her own gelatinous flesh. She felt the Ellie crawl onto her, noticing she was becoming more acclimated to climbing the giant fleshy water bed that was her best friend. She felt her friend climb closer and closer, eventually reaching her torso. She sat down next to Alexis, her body sinking quite far down into Alexis’ humongous built-in cushion.
“So I made you this thing for today, it’s just a twelve pack of soda but I put a strap on it so you could carry it!”
“Thank you so much Ellie!” Alexis squealed, trying her best to hug her friend with more than just her ass.
Ellie crawled off, going back inside to watch TV. She felt the ground shake, looking out to see Alexis rising up to go off walking again…
~~
Alexis returned several hours later, her arrival foretold by the distant thuds of her 6 foot wide hooves on the ground. Ellie heard a large boom, looking out to see Alexis jiggling around on her huge ass. She waved, with Ellie waving back as she received a text.
A: hey whats for din
E: uh more mac and cheese?
A: great!!
Ellie cooked up another family size, this time getting a small one for herself so that Alexis could get all the calories she needed to move. She crawled up Mt. Alexis again, balancing well the large mac and cheese as she went. The two once again ate together, Ellie departing soon after Alexis finished her huge plate of mac and cheese, taking the now empty 12 pack back down to her house with it. Alexis felt Ellie once again jump off of her ass, but this time, she slapped it after she landed. “Something tells me, she doesn’t exactly mind my body…” she thought, smiling slightly.
They both slept well, eager to know if their experiment had worked…
