So he headed of to gym. Ty thought he'd have a bit more fun with dustin. As soon as dustin went in the locker room he felt a tingling in his crotch. He quickly ran to the bathroom to find his dick shrinking. It became smaller and smaller untill it was only 2 in hard and as thin as a pencil. Dustin was about to cry as it got hard. Dustin went in to the locker room thinking no one was there to dress he put on his jock strap and became depressed when he saw there was no bulge. He stuffed some klenex in it to make it look like a bulge. He saw ty standing at the door and asked him why he shrunk his cock. Ty said he wanted to teach him and the rest of the gym class a lesson. Dustin said how does this teach everyone else a lesson. Ty said every time someone makes fun of you their dick will shrink untill its as big of yours. Dustin said at least I can pound anybody who makes fun of it. "Oh no you can't said Ty. We can't have anybody getting hurt." Dustin slowly started to loose muscle mass and height untill he looked like a gangly teen. Dustin cried as Ty swiped his hand and the klenex dustin stuffed in his crotch dissapered showing how truly bulgeless he was. Dustin's clothes got tighter and turned in to a speedo that revealed his tiny cock. Dustin had no choice but to go back to class where they where learning swimming. Jim the star basketball player of the team saw dustin and asked him if his dick would be visible after it shrank in the water. The whole class laughed. Suddenly Jim felt a lightening feeling in his crotch. His 8 in cock and golf ball sized balls soon became a nub and marbles. Everyone gasped as the saw his bulge in his speedos get roomier. He yelled "what did u do to my dick freak?" Jim now had the same size cock and balls as Dustin. Jim's cock soon shrivled again to half its size as his balls were almost gone. Jim screamed what are you laughing at to tim who was a freshman standing at the door. His dick just started to develop and he was proud of his cock. He then felt the tell tale signs. His newly developed cock was forced the other way of puberty. His dick first became extreamly short. That made it look almost fat because of its small lentgh. It the thined out an just stood there pointing. Just then the coach said class was over. Everyone headed in to the locker room. Ty was in the locker room he said "You all need to learn some modesty." Everyone was puzzled as they were undressing and in the shower. The boys in the shower started to loose height and wieght untill they looked like thin gangly freshmen boys. They were all releaved to still see their cocks at their old size. Then Ty said I amlost forgot. Freshmen boys can't all be running around with junior and senior dicks. All the boys looked fearful. "I think fourth grade dicks would be much more appropriate. I don't think fourth grade dicks have any hair on them either" Ty said. With that the boys in the shower's dicks were hairless. "I think you should expeirience the shrivleing of your cocks." "Your cocks will shrink to the size they were when you were in fourth grade over an hour." One more thing, fourth grade dicks don't get hard although you'll all be very sexually fustrated" said Ty. One of the boys said "why are you doing this I didn't do anything to you." Ty said, "You tormented boys in middle school about being underdeveloped didn't you." The kid sighed. Ty then progressed his size and made it quickly dwindle to a half in. Ty said, "You better sit down when you go to the bathroom. As for the rest of you still changing if you've ever given anyone a problem about anything your dick will shrink then next time you piss." Then Ty made all there bladders heavy. They'd have to go soon.
