Mary backed away from the dish, her body tingled all over, and began to shudder. She felt so strange, and rather bloated. She couldn't help thinking she drank to much. In just a few seconds, she began to hear a sound...it was quiet, even for her tiny mouse ears. She looked about the room, and saw Jess wasn't about. She wasn't waiting for another chance and ran to the side of the cage. Mary made several desperate tries to squeeze through, but found she was too large. That sound suddenly started again, yet Mary couldn't work out where it was coming from. She though maybe Jess was planning something, or maybe she was coming back. Mary threw herself into the bars once more, and suddenly popped right through them.
"How did I do that?!" she squeeked quietly, "I was to big a moment ago!"
She didn't hang about long, and began to run for somewhere to hide. Yet just a few seconds afterwards, a feeling of sickness spread through her stomach. Grasping her belly with both paws, she fell to her knees. That sound came back again, and mary knew what it was this time, it was the sound of stretching rubber. She still couldn't place it until she suddenly lost movement of her tail. Looking behind, her tail was stuck strait out behind her and swelling. Mary quickly looked at her paws, which had started to take on a rubbery sheen. Infact her whole body was changing. Jess had obviously put more that one vial in that liquid, and Mary was getting the effects of them all. As she was about to go back to the cage, she lost the movement in her legs. They, like her tail began to swell, as did her paws and arm. Soon even her belly became largely bloated. She couldn't believe what was happening, yet something made her look about whilest she could. Everything seemed to be getting smaller, she knew it was just her growing though...no, not growing, inflating. She was becoming a giant mouse balloon, and could do nothing about it. She had already tripled in size, and was still swelling up. Just at that moment, Jess returned.
"My aren't you a good size now" She smirked, "I knew you'd try something to get the upper han...paw. So I added something extra"
Mary could make no response, as her whole body had now morphed into a swelling toony mouse balloon. Jess came closer a poked Mary with a claw.
"You're quite the cat toy now, I'll look forward to playing with you later" She laughed, then sat back to watch.
Mary was still inflating, and was now starting to get bigger than Jess. How much bigger could she get...?
