"Oh, I cannot believe I'm stuck as Charles' sock, now? I should've changed myself into a buff guy instead of sock," thought Cory.
Charles froze with a start, and looked down at his feet. "Cory? Hm? Make me buffer, 176 lbs and 6'0 and with more body hair," demanded Charles.
As he stood in front of the mirror, Charles watched and grinned as he rose from 156 lbs at 5'9" to his new and improved 6'0" muscled self. His wrestling singlet strained as he went from Large to Extra Large.
"Thank you, Cory. I wonder what else you can do? Well, I'll find out after wrestling."
"Charles? Are you taller?" Coach Murphy asked.
"Yeah, I think, I'm in a new weight class," Charles said smugly, "So I guess, I should be sparring with Mitch now." He grinned.
He thought at Cory, "Hey, Cor, how about shrinking Mitch's cock - wait until he tries to pin me, then make it 1/2 inch long."
Huh? thought Cory.
Or else I'll never take you off, Cor. Do as you're told.
I don't know if it will work? I've never actually done it to anyone but you and me.
Hm? Okay, then, Cor, let's assume it requires direct contact. When I press you up against his leg, then you try changing his cock - oh, and his balls too, make 'em doll size, thought Charles wickedly.
Cory realized that Mitch had been bigger than Charles, but that was no longer the case. Charles couldn't bully him before, but Mitch had never stopped Charles from bullying everyone else, so he didn't feel that bad about obeying Charles' orders.
