Ben enjoyed to toy with this former bully kid but he can't stay doing the same for too long. He was getting bored. So, he started to get more creative and turned the boy into different things while he tried to increase his interest on him.
Ben turned him into candy corn, then into a worm, an ant, a lollipop and a piece of cheese. Ben realized he was getting hungry but he can't simple turn this kid into food and eat it. It was like killing him and Ben could get a lot of troubles because of that. Maybe he could become something that can provided him food... That's it! He now has an idea!
Ben tool the kid and made him grow back to his original size. The boy grew a lot but he ended up being way more smaller than Ben remembered him. So, Ben decided to adjust a few more things about him before he turned him into his final form.
First, he aged him up 15 years. So, the kid wasn't a kid anymore. The young man in front of Ben didn't look particularly handsome or so, but he wasn't totally ugly either. You can say he was a average in every possible way. Average muscle definition, average height, even average dick size, which wasn't too bad to be honest.
His body hair wasn't as prominent as other grown men. Just the necessary amount on his armpits and crotch. He had a few hairs on his chest but it was barely noticeable. Of course he didn't have a beard neither, just a few sparse hair on there and there. Ben didn't immobilize him, he just glued his feet to the ground and closed his mouth, so he can't run away or scream for help.
This gave the guy plenty freedom to explore his new adult body, touching every corner of his extended flesh, especially the loose scrotum that he had gotten when his balls dropped. In another situation, he would be ashamed of being naked in front of anyone else. But, he now has some kind of peace inside him, enough calm to enjoy the short opportunity to know how he will look in his future.
However Ben didn't lose his time and his second change was already happening. The guys pink flesh was turning into metal. First silver gray metal but then getting some metallic colors, green, red and yellow. His torso was widening along with his neck, until they were equally thick and fused into a single piece. He was getting so big that his weight was too much for his legs and he fell on his butt which was also getting bigger and bigger.
When he noticed what was happening with his body it was too late. His body was basically a colorful metal box at this time, with his arms and legs shrinking into nothing as seconds passed by. His head had already fell down and his facial features were turning into simple drawings on his metal box body.
Then, his belly turned into glass and Ben could see that his internal organs were quickly turning into metal devices, wires and stuff. Ben smiled when it was pretty notorious that he was getting a vending machine full of soda cans, candies and chips. The only human thing remaining on the guy was his dick which was already turning in the last piece of his machine, the hole where food came out.
Ben got closer to the former boy and inspected it. He realized he needs to be connected, so he managed to push him to a wall and plugged it in. The vending machine immediately came to life and Ben pushed a few buttons to get a bag of chips and a soda can. He was very satisfied with the result, but Richard, his nephew, who also watched his friend is turning into an object, was completely mortified. Especially because he knew he was next.
