Tsuki was a gray-furred lynx that stood at about 6 feet in height. In her hand she held a small bottle of pills, the bottle labeled “Rubberlife Inc. Transformation Pills”. Near her stood a pink-furred chinchilla who had a bike pump next to them, and a smile on their face. Said chinchilla was named Marna, and he was a large fan of inflating himself to huge sizes (pun intended). Marna held one of the pills from the bottle in his free hand, and he was simply giddy with excitement for what was coming.
Tsuki found Marna’s interests somewhat strange, but didn’t question it too much. Marna, still smiling, said, “I’ll say when to stop. No matter what you hear from my hide or anything like that, just keep pumping, okay?”
Tsuki had been told this multiple times, and just nodded again. “Yeah, yeah,” she said, “I got it, I got it. Just keep pumping until you say not to.”
Marna chuckled and popped the pill into his mouth, swallowing it and looking at his middle with excitement. Immediately, his fur began to gain a sheen to it, smoothing out and looking like something that wasn’t even fur. Then, the change spread to his tail, head, legs, and arms. He slowly became somewhat transparent, and a seam began to form down the middle of his body.
Marna giggled a bit as the transformation happened, his middle beginning to puff outward slightly as a valve formed where his belly button was. When the transformation was complete, Marna was smiling with glee and pride as he pointed at the valve and said, “That’s where you’ll pump into.”
Tsuki chuckled but obliged, quickly opening the valve and putting the hose inside to prevent any air loss. She assumed Marna was full of air now, and also that losing much of said air could prove dangerous for the chinchilla… or pool toy, she guessed.
Marna looked excited as ever, and was bouncing up and down a little. He nodded to Tsuki, giving her the go-ahead to start pumping. Tsuki did exactly that, bringing the handle of the pump up and down to send some air into Marna. Changes were noticeable even in the first pump, as Marna’s middle quickly expanded outward slightly. The chinchilla giggled and pressed on his middle, which squished beneath his rubber paws, resulting in Marna only giggling at a slightly louder volume.
Tsuki pumped again, and again, and a few more times before Marna’s stomach was the size of a basketball, and Marna told the lynx to stop for a moment. Tsuki looked slightly confused, but that confusion quickly faded as she saw Marna drumming on his middle, receiving a drum-like sound in return. To Tsuki, he showed a surprisingly small concern for himself considering his hide was already taut enough to sound like a drum.
Marna gave Tsuki the signal to keep pumping, and the lynx did exactly that. More pumping led to the continued growth of the chinchilla’s stomach, and said stomach eventually became the size of a beach ball before the rest of the pool toy’s body began puffing up as well. With his chest already having become one with his stomach, Marna’s legs and tail were the first things to be affected, becoming fatter and fatter as air pushed into them. Then, his back began rounding out as his arms began inflating as well.
Soon, Marna looked rather spherical, and creaks were beginning to emanate from the rubber material that was the chinchilla’s skin. His size rivaled that of a small car, but he still seemed to show no signs of being even slightly stressed. His cheeks had puffed up around his snout and rounded out, while his head as a whole had begun to sink down into the rest of his body. His tail had become a dome on the back of the sphere he now was, as had his arms and legs, with his paws being immobile, puffed up tips of these domes.
The numerous creaks continued to grow louder and longer as air was pumped into the pool toy’s body. Eventually Marna rivaled the size of a bus, and that was when Marna let out a moan. The pressure had begun putting him in a daze, and the chinchilla didn’t have much time left before he would be too incoherent to tell Tsuki to stop pumping. Thinking of this, Marna spoke to the lynx, “That’s- unnnh- enough…”
Tsuki stopped pumping and took the hose out of the valve, again making sure not much air escaped before she could plug the hole. The lynx rolled the chinchilla onto his back and prodded his stomach, producing multiple moans from Marna and creaks from his rubber. Marna was almost thoroughly in a daze now, and it wouldn’t be until Tsuki deflated him that he would come out of it. The lynx got a few ideas as for what to do with this, however, and a mischievous grin appeared on her face as she thought of the idea of sleeping on a chinchilla…
