Jake saw his face was starting to shift. The fat in his cheeks was draining away, leaving his face with a curve you would see only in models. Then his eyes lightened up to a bright green in them. Jake was startled, but still couldn't move at all.
He then noticed something, his skin was darkening in splotches as well as his hair. His hair was darkening a lot quicker, and seemed to be shrinking down from it's fairly long "i don't care" length. He looked down and saw his arm was moving towards his crotch, even though he had absolutely no control over it. His hand reached inside of his boxers and pulled out his cock, pulling the boxers down.
He felt his hand on his cock, slowly working it and it growing to it's usual 5" but it didn't stop. Looking down at the area, the skin had darkened to a golden tan, which was a surprise as he previously looked like paper almost. However, just above his cock the layer of fat gathered around his waist he noticed something was different. It was being sucked in, but not only that he felt his bones wince with pain as he noticed a slight rise in his height, slowing increasing as more of the fat was being pulled in.
In it's place revealed a tanned flat stomach with their hips showing the V shape many would lust for. A smile crept on Jake's face as he was beginning to enjoy this change. He also looked and found the jacket was now his size, which was also good.
Then a jolt of pain hit his penis, capturing his attention as the foreskin on his penis seemed to almost fizz away, leaving an 8" cock. Then he felt it in his chest as his skin tightened up to reveal toned pecs, and the pain moving down as the skin tightened to reveal a 6 pack in it's glory.
His hand worked his cock even more now, and he felt something in his mind this time as his brain was feeling pleasure. His usually active and curious mind seemed to slow down and decided to focus on his body, his glorious body.
"Awww fuck man," he spoke, his body giving way at last to his brain's need to control it. But his voice was at least a few octaves deeper, and the thought of it was just brilliant to Jake's mind.
Then he felt a release as he sprayed cum over the mirror. Upon doing so, all of his concerns seemed to fade away. However, he still retained the memory of his old life, he loved what he would be able to do.
"I suppose everything is okay in there," the clerk asked suddenly pulling Jake back to planet earth,
"Oh shit man, sorry about that" he spoke after the clerk had opened the door on him,
"Don't worry about it. Looks like you're going to need some new clothes. Don't worry, we can swap these old things considering you won't be needing them,"
The clerk removed the old clothes and even took the boxershorts. That slightly worried me, but the clerk returned with a box of clothes which seemed to be what I wanted to wear. I pulled on the expensive looking black jeans and while there were a shirt in the box I decided that would only hinder the beauty of this body.
