Erick was walking into what looked like a living room when a thin green smoke began to leak through the floor and walls, it filled the room with a mysterious atmosphere but Erick didn't seem to notice it.
Erick was looking at an old book when he felt an odd feeling though out his body. A second later, he was leaning on a shelf grabbing his cramping stomach. The old book had fallen out of his hands.
"Ehhhh...uhhh...my stomach... hurts." Erick mumbled to himself. His hands now holding onto his stomach, He felt like his stomach was growing in his grasp. His hands grabbing around his swelling belly.
"Uhh, wha?? What's happening with me...?" His jersey and jeans were getting tight from his growing belly. Not only that but his arms and chest were swelling too. His legs were bulking quickly, gaining mass like a balloon filling with water.
His pecs pushed out turning into man boobs, his fingers and toes looking like sausages right now, and his neck getting covered by a fat double chin. He was panicking, he tried to leave the run but he can't move like he used to.
Meanwhile, a thick pelt of chest hair began to push out, spreading across his massive chest and going down through his beach ball belly. He can feel it growing in his face, even on his double chin and giving a very uncomfortable itchiness.
He was huge now and it seems he's still growing. Erick kept putting on more mass, his height increasing a few inches followed with more fat. Before long Erick looks more like a dirty old slob, than a young athletic teenager.
His body had gained so much size and mass that his clothes ripped of his growing body. His pants, now impossibly too tight, ripped off, revealing his hairy sturdy legs, but most impressive, the huge package between them.
"Oh fucking hell!!, I'm... I'm so huge now! I'm a fucking ball of lard!" Erick's voice had grown very very deep now, his face, formerly a handsome one, was covered in hair, fat and tears. He had grown so much that he felt tired and instead of looking for help he just stayed there crying.
