You look around at the other guys and you think about the possibilities. You're satisfied with what you've done to Chuck. You don't plan on letting him off the hook but you don't plan on adding any more humiliation unless he does something to deserve it. Now you think of other targets, other guys you want to make voodoo dolls of.
Chuck had been the worst but he hadn't been the only one to be mean. Billy snapped you with a towel. He snapped other guys too but maybe you could get him back for the towel snapping. Roger got ahold of one of your homework assignments and shredded it so that you couldn't get any credit for it and it was a big assignment. Chad was just a conceited jerk. Chad never did anything to you but you still want to humble him. You could go on listing names of more guys to humiliate: Ryan, Jeff, Jared, Mike, Dan, Hank, . . .
At lunch, Chuck comes up to you. "I know it was you who did that to me."
You ask, "How do you know."
Chuck answers, "You were the only one acting different. Everyone else acted surprised and laughed but you hung back as if you were taking the whole scene in. How'd you do it?"
You say, "A magician never reveals his secrets."
Chuck asks, "Can you change me back? I don't want to have a tiny dick."
You say, "I can but it all depends on how you treat me. If you work against me in any way, including telling secrets, I can do much worse to you than just shrink your cock."
Chuck said, "Mr. Aldrich thinks I used a fake dick to get out of math class. He extended my detention. Please at least let me prove that it wasn't fake."
You asks, "What will you do for me?"
Chuck asks, "What do you want?"
You say, "I don't know yet but you'll owe me a favor that I can call on at any time."
Chuck says, "Thank you. Are you going to make it grow now?"
You say, "No, I'll make it grow just in time and shrink afterward."
Chuck thanks you again and leaves. You do have another ability with the voodoo doll. You can watch what is happening to Chuck on a screen as if you were getting a video feed on a smart phone. You didn't use this ability before because you're still trying to keep your voodoo a secret. But this time, you have the screen set up and you watch Chuck while he goes back to detention.
You watch as Mr. Aldrich reminds Chuck that he's in detention for using a fake dick to get out of math class. Chuck says, "But it wasn't fake. It just shrank later."
Now is the time. You mess with the voodoo doll making Chuck's dick grow until it's out of his pants again.
Mr. Aldrich says, "You brought the fake dick again. I'm going to have to confiscate it." Mr. Aldrich grabs Chuck's cock and gives it a good yank. "You have it attached somehow? Remove it."
Chuck says, "It's not a fake. That's my real dick you're yanking."
Mr. Aldrich almost says, "Quit back talking." but Chuck's pants help prove Chuck's dick is real by falling down to his ankles. Chuck stands there in front of the detention group with his lower half exposed and Mr. Aldrich still yanking on his dick.
Mr. Aldrich let go quickly, "Sorry, I thought it was fake. But you're still in trouble for masturbating in class. Now shrink that thing down again."
Chuck almost says, "I can't just think away an erection like that." but you help him by shrinking his genitals to tiny again.
Mr. Aldrich says, "I've heard of showers and growers but I've never seen such an extreme case of shrinkage before.
