Picture 1:
It was a subtle thing when it happened. Asriel hadn’t had his old form back for that long, certainly not long enough by his estimation, but he knew what was happening when it began. All the years spent outside of proper time had made him a bit sensitive to the fickle nature of the world’s FUN value. His old, childish body had been held together primarily by tension and memory, and those two things weren’t sufficient by themselves. The tension was fading in the presence of his family, and the memory – that had been twisted for so very long now. It had been a mercy he didn’t end up part flower when everything shook itself out.
None of this made the moment comfortable when it struck. Asriel nearly fell from a sense of vertigo that descended on him, reaching out for something to steady himself with and not finding anything present for it. Not in arm’s reach anyway, there was a tree not far out, but he’d have to stumble over to it. If nothing else, he was glad this happened somewhere private.
Asriel whimpered quietly in the beginning, there was a degree of pain to it – a bit like a muscle in the process of unclenching after a nasty cramp, only all of him at the same time. Which made him grateful it was brief. Though even as the pain subsided into something more ephemeral, it was clear the problems weren’t over. Asriel had some experience with sudden catastrophic shifts in size, which made what was happening to him now a bit mild by comparison, but in the other events he hadn’t been wearing clothing. That, it turned out, was an important detail.
Everything went tight at about the same time, though not to the same degree. Asriel felt himself loosen and thicken inside as a rush of weakness left him hurrying to the tree, leaning against it while he tucked his arms around his chest. At the waist and below things got uncomfortable quickly, jeans were unforgiving garments for a body thickening all at once. Even getting a hand under the waistline to unbutton them was a bit difficult, but it also saved him a lot of agony. If he rubbed his hips against the tree right, it even started easing the waistline down a bit.
Handling his chest was easier, the shirt was a much more manageable garment to deal with, but it seemed to be contending with a lot more growth as well. Asriel hesitated as he took in what was happening. The whole thing had filled out in a heartbeat, but some of it more than others. Looking down at himself, Asriel saw two comfy, soft mounds forming through the opening in the shirt collar. Plump, pressing against each other, nipples digging into the shirt fabric, the whole thing tugging it upward a few inches and leaving some exposed belly around his waistline. More of it as his jeans slid slowly, mercifully lower.
As the strange weightless sensation crept through his body, Asriel was at once worried about what more would happen before it was done, and relieved that thus far it didn’t seem that bad. Though as the phenomenon took a turn between his legs, a fresh kernel of concern formed in the back of the monster’s mind.
