Shortly after the previous "victim" left, a kid around the age of 8 walked in. The surprisingly already had a decent build in muscle and seemed to be obsessed with power. His name was Jayden.
Dustin, using his xray vision powers, looked through the wall to see the kid was changing. Dustin thought to himself "I had fun with the other guy and this kid seems to like muscle, so I am going to help him. Just a "little"bit help not much"
So Dustin stared at Jayden and watched as the kid grew little by little. A little in cock, a little in height, and a little bit more in the muscle department.
Jayden must have caught on because he started admiring himself. Jayden actually had his own special "power". He could sense where the grow was coming from.
Dustin and Jayden had a miniture state off while Jayden was still growth. It went for at least 2 minutes. Jayden opened the door looked around grabbed his stuff and broke his way into Dustind little room.
As Jayden walked in he demanded an increase in power of the growth. Dustin, who was surpriseingly intimidated, answer that with a yes. So right before his eyes, he saw an 8 year old grow to his height, grow to double his muscle mass and a cock that would put that other guy to shame.
Jayden got so big he had to get out of the room to continue to grow. And to make sure he did he tied Dustin so he had to look at Jayden. Jayden grew and grew and grew. He clothes changed into a tight muscle shirt, some tightish shorts and sandels. By now Jayden was the double the height of Dustin, who himself was 6ft, double the muscle mass of a 40 year old body builder who had been working out since he was 15 and a15 inch cock.
Jayden made sure that if he wanted to grow al he had to do is go grab Dustin and make him stare at him. Still at this moment Jayden was still growing. Taller, stronger, bigger, and longer. Shortly after that Jayden made Dustin sit there while he jacked off. Jayden sat there wait for his load to blow. He could feel it pumping after 2 minutes. When he reached his peak, the cum came out in a fountain and sprayed everywhere. In Dustins face, mouth, etc. all over the walls, in his own mouth.
Jayden ended up sucking his own cock and you could see that he was still cumming. The thing was everytime Jayden took a big gulp, he grew another inch in all departments. Dustin didn't know what to do.
