(Hi guys, I'm trying a different direction for the Ty's Power story other than Ty being all powerful through wishing. The idea behind this storyline is that if Ty causes a change in someone, the opposite happens to him. Like, if he tries to make a friend younger, Ty will gain the years they lose. If you find this idea interesting, it'd be great for you to add on.)
Ty felt a tingling across his body, a tickling. He was unaware of what was happening, but he was slowly getting taller, his muscles were developing, his body hair was filling in, and his dick was growing. Ty stood from his bed and walked over to his dresser to get some clothes when he caught site of his reflection in the mirror. Startled, he looked over. His mouth gaping at the guy who stared back at him. 6'0" tall, nice, lean muscles, a 5 and a half inch dick. He looked like a real teen now, and not the scrawny boy he just was! He had stolen Dustins development somehow! He rushed out to the bathroom, pushing the smaller Dustin out of the doorway, causing him to drop his towel. Ty jumped on the scale and read off the number 170. A big jump from 125.
Dustin slowly pulled himself up and looked at Ty. His eyes went wide at how big his little brother looked compared to him. "T... Ty?" He stammered. Ty looked over at Dustin, who looked even smaller now. He grinned, and grabbed his brother by the shoulder, pulling him into the bedroom. "Dustin, we're gonna do a little test." He said with a grin. Closing the door, he looked over Dustin. He looked like Ty had just a few minutes ago. He needed to do something to Dustin in a wish... but what? He was scrawny, little, didn't have any muscle to take or anything. Ty looked down at Dustins 3 inch dick and grinned. He wished that Dustins prick would shrink to a half inch.
Ty looked down smiling as the wish took effect. A tingling in his crotch alerted Dustin to look down as well. As he did, he saw the tiny prick shrink a little, pulling in toward his body, then again, and again, until only a little Nub stuck out from the sparse hair around it. If Ty was right about whatever these powers were, his dick would get a bit bigger in a second. As dustin poked at his tiny nub, speechlessly, he looked over at Ty, who was staring at his own crotch. His eyes went wide as the average sized cock started to grow a bit, expanding slightly, growing thicker and longer. It crept up, 6, 7, 8 inches. It hung heavy from Ty's body.
"Yes! I was right!" Ty said. Dustin was still speechless. "Whatever I do to someone, the opposite happens to me!" He smiled to himself. Dustin knelt on the ground, looking up at his developed, well endowed foster brother. Only he could change him back. "Please Ty! I don't want to go through puberty all over again! I worked hard to get that body! Please don't leave me this way!" He said, pleadingly. Ty looked down "Get up Dustin. I'm not changing you back right now. I just think you need to see what it's like to be the little guy. Once I figure out more about these powers, I'll change you back." Ty said. Dustin hung his head. Ty walked into Dustins bedroom and looked through the drawers for something to fit him. Coming back in a pair of jeans and a red t-shirt, he threw some of his old clothes at Dustin.
"These should fit you. We're going out to see what else I can do with these powers." Ty straightened his shirt. "Hurry up"
