Jessie sat on his bed. Nick seemed to be getting bigger and bigger, just as he'd planned. Of course, his bed seemed bigger, and Nick's bed too. Jessie's vision was impaired momentarily as his shirt covered his eyes. He stood up, inching out of his pants. Why would he be wearing pants and a shirt? He never wore anything normally.
Nick stood up next to his bed. Jessie seemed to be getting smaller and smaller, just as he'd planned. Of course, his bed seemed smaller, and Jessie's bed too. Nick had momentary feeling of short breath. His clothes were becoming too tight, stretching out for some reason. He took off his pants and ripped off his shirt. Why would he be wearing clothes? He usually went nude everywhere.
And as Nick suddenly had to sit down, the last of Jessie's clothes fell off of him. There he stood, at 6 inches tall. Jessie's muscles had somewhat grown, just as Nick had intended despite Jessie's small stature. Jessie looked up to see the comically tall Nick and laughed. It was quite funny to see him inadvertently struggle to stay in the room.
Nick moved to the floor as he filled up more and more space. His underwear tore as his muscles bloomed outwards. He laughed a hearty laugh at how small he had made Jessie. He was real cute standing there.
In an odd twist of irony, Nick had made Jessie ten times smaller than he was originally. Jessie had been only five feet tall. Jessie on the other hand had made Nick ten times taller. Nick was five foot six and would not fit in this room much longer.
Nick never seemed to notice the fact that he had to bend over in this room. Soon however, he broke through the wall of his room with his foot, flattening a student passing by in the hallway. He punched a hole through the other wall and crawled outside to stretch. He hated cramped places. He stood up waving to some of his friends who waved back like all was normal.
Jessie hopped down off of his bed and ran towards the hole to see the ten foot long foot wiggling its toes. With a mighty stomp, it moved out of the way and Nick leaned all the way down to look inside. His eye was almost a foot in diameter.
"Do you notice the changes yet?" the booming voice of Nick said.
"Do you?" called out Jessie. He grabbed the covers of Nick's bed which had dipped down from the initial pressure of him sitting on it and climbed up it. Being so small, Jessie had had to be very strong in order to parkour his way around places.
Outside, Nick took in the fresh air. Being so large, his muscles were naturally large and strong in order to support such a monstrous being.
Jessie set a timer for 1 hour until they would become aware. Until then, he'd try and figure out how he was different and maybe try and mess with Nick. If that was even possible from his size.
