"Let me think about this, okay? I don't like to give others the same kind of power that I got. We'll see..." Peter said, as he turned around.
Allen seemed kind of sad, because he really thought that Peter trusted him. Just as Allen turned around, he saw Ty standing behind him with a grin on his face.
"Hey Allen" Ty said to him, "You really like peter, huh? he's my cousin, you know?" Allen had a sad look on his face. "Well, look, I won't want to do anything to harm my cousin, but I don't think you are out to harm Peter, right?" Ty asked him. "No, of course not. I just wanted to have some fun with him. I mean, he gave me the power to shrink and grow his muscles already" Allen responded.
"OK Allen, I got the power too, and I'll give you just enough power so that you can transform Peter any way you want. But you can only transform Peter, nobody else! Got that?" Allen just nodded. Ty closed his eyes and concentrated for a few seconds. "Okay, you got it. Go have some fun with Peter, but be nice!" Ty warned him.
Allen saw Peter at swim practice. They did their laps and practiced hard. After practice, Allen saw Peter alone in the locker room.
"Hey Peter" Allen said, as he walked up to Peter, who was naked and still wet from coming out of the shower. "What's up?" Peter asked Allen. "You are!"
Suddenly Peter grew a foot taller, as he noticed the room was suddenly shrinking around him. "Whoa! Hey, did you do that?" Peter asked him, looking down at Allen. Peter was now 7 feet tall! Allen looked at Peter, and noticed his pectorals. Suddenly they began to grow and Peter became wider and wider. "Oh no! I'm getting too big! Stop it, Allen!" Peter said, almost in panic. His chest was over 4 feet wide.
Allen looked at Peter's endownment. Suddenly his cock became as thick as a hose and it grew to 8 inches in length. "Whoa! oooh Allen..." Peter said. Allen was laughing it up. Then Allen concentrated, adding 5 inches to his cock. Peter gasped as his 8 inch tool grew to 9, 10... Finally it was 13 inches long!
Peter just chuckled. After all, Allen was his friend and he was having fun with his powers.
"Let me see... What else can I do to you, buddy?" Allen wondered out loud.
