Dan thought about how big he might want to be. Did he want to just put on a little bit more weight? Or did he want to get really huge? The more he thought about it, the harder his dick got - he'd always repressed this urge to get fat, but now with the Chronivac he could see what it was like, and if he decided it wasn't for him, he could just change back!
His fingers were shaking as he updated bis profile. He changed his weight from 270lb all the way to 700. The body type option still had muscle bear selected, so he changed it to fat. He read down the other options and found a free format box - not knowing how the machine could interpret free text, he decided to type in 'Dan is now a huge fat guy, but with no harmful health effects - he's as healthy as he always was'
Dan's leg was bouncing in anticipation and his cock was leaking pre onto the floor. He looked down over his muscle bear body and smiled. He rubbed his pecs and thick arms, 'that's the last time I'm going to be muscular for a while' he said with a grin, and pressed 'Proceed'.
He felt the familiar warmth flood through his body as the changes started. He raced over to the mirror to watch them, and quickly started to see what he'd dreamed about for so long. His pecs started to soften and bloom into small moobs, first the nipples getting more pronounced before they started to expand and droop onto his belly. His gut was blowing out from being a small mound (it was strange to think Dan had thought his gut was big a few minutes ago!) to a larger, softer belly, spreading out into love handles at his sides, and then starting to hang down to obscure his once-ample cock. His fat pad grew so much that his once-8-inch dick was completely buried in soft, warm fat. His ass and legs expanded to be huge, wobbling tree trunks, and his back went from back a broad V shape to more like an A - his shoulders much narrower, expanding towards his enormous belly. His fingers and toes became thicker. His face and neck filled out too, so much that his chin disappeared and his whole face became much rounder.
Finally, as quickly as it started, there was a beep to say it was over. Dan looked in the mirror and almost came - between the feeling of his belly enveloping his dick to the sight of his huge new body, he was incredibly turned on. He took his colossal belly in both hands and started to bounce it up and down - it sent shivers through him and his dick felt like it was going to explode - it's like he was fucking his own fat pad. He reached up to squeeze his huge moobs - fuck they were sensitive now! So sensitive that he came with a gasp, his cock pumping a hot sticky load against his underbelly. The afterglow lasted a few minutes at least - Dan hadn't realised how good it could feel to be fat!
He was about to get in the shower to clean off when he realised - he might love being huge but there was still the stigma in the world about being fat. So Dan sat down at his laptop again (noticing the Chronivac had been kind enough to give him a reinforced chair) and entered something else in the free format box. He typed 'fat is the natural state for humanity. Even the thinnest people are what would currently be considered obese. The fattest people are looked up to like bodybuilders or supermodels. The fatter you are, the healthier you become. Fat is sexy and everyone loves showing it off - gay guys especially'
He pressed 'Proceed', and knew instinctively that the change had worked even though nothing changed with him. But he was so excited to see the world he'd created so Dan decided to...
