Ty tried hard to keep the hunky body he had been given, but he just wasn't a gym guy. He felt hungry more often, probably because his new muscles always wanted food, but he slacked off. First, one day away from the gym every few weeks. then one a week, then 2. Soon, he was skipping the gym, but still eating ravenously. The pounds just seemed to pile on after that. Ty's muscles shrank on a daily basis, and were covered by a layer of fat. His flat abs had arched out over time, becoming a distended, fat belly. His pecs lost tension and turned into tits, and his ass inflated into his pants every passing minute.
He woke up on his 18th birthday and climbed out of bed. His boxer breifs were tight across his fat ass... must've been a pair from his thinner days. His scratched his gut and lumbered into the bathroom. He felt his body jiggle with his footfalls. In the bathroom, he did his business, took a quick shower, and as he had done every day for the past few years, checked his weight. 276 pounds. He checked himself out in the mirror... he didn't look so bad for a fatboy... right? Soon, his hazy morning thoughts were clear, and he remembered that today was the day.
"Could... could I really have those powers promised to me?" He rubbed his gut. "How do I even use them?". A note fell from behind the mirror. Ty picked it up cautiously and read the words "just wish it."
"Just wish it, huh? I think I can handle that... but what would I wish for?" Ty looked himself over. His fat body jiggled when he turned. "Maybe I can wish for my muscle body back?" he thought, but he shook his head. Honestly, he kind of liked being fat. He felt very dominating. He remembered Dustin teasing him about his weight a few times, saying that Ty was well on his way to 350. He could try that. Ty was fat, but he wondered what it might be like to be REALLY fat. Why not one up Dustin though. 350 wasn't too far off, so he decided to try for more. he crunched the numbers in his head, and finally came up with his wish.
"I wish I'd gain 224 pounds of fat." Ty said aloud, then waited... nothing seemed to be happening... then a tingle occured in his gut, then spread across his whole body. He looked in the mirror and his eyes went wide as he began to grow fatter. He grinned widely as his body thickened. His belly puffed out in front of him. He felt his ass filling his tight boxer breifs, his thighs stretching the leg holes. His chest grew bigger, and his arms inflated. "This is amazing!" He chuckled, grabbing his gut as it grew larger between his fingers. His boxer briefs moaned as his fat body grew too big for them.
Ty wobbled a bit as his body grew. He had to adjust to the new weight on the fly. Ty turned slightly, grinning at his ass outgrowing his underwear. His huge body seemed to fatten endlessly. His underwear split on the thighs first, then the seat, and soon the waistband popped too. The fat, naked 18 year old marveled at his every growing frame. His reflection was almost too big for their mirror! Suddenly, his growth stopped.
Ty looked himself over. He was a massive fatass! He stepped on the scale. It groaned loudly, and read error. He was too big for it. it groaned again and cracked. Ty felt really turned on by all this new size, and felt his cock growing hard. Ty checked himself out in the mirror one more time, and caught glimpse of his cock... god, being this fat made it really small... no matter though. he grabbed on anyway and got to work.

Ty waddled out of the bathroom after a knockout session and squeezed himself into his room. He looked for his biggest clothes... nothing to fit him like this. He settled for a button up shirt that didn't button and a pair of jogging shorts, which looked painted on. Ty decided to go out for the day.... where should he go?
