You walk to PE quickly, eager to see the stupid look on Chuck's face. You arrive at the changing room just as he's about to take off his pants no doubt hoping to get into his PE gear before anyone has a chance to glimpse his tiny cock. However, after hearing you approach he quickly pulled his pants back up, then paused to glare at you.
You pretend not to notice as you go about getting changed. After pulling down your pants you turn around and think you catch him peeking at your average sized penis with envy before the two of you make eye contact.
"What are you looking at?" he snaps.
"Aren't you going to get changed?" You grin at him with a smug expression. He's changed his shirt but is still wearing his normal jeans.
"Not with a fag like you watching" He mumbles before turning his back on you as the rest of the class arrives and starts getting changed.
You watch as he pretended to fumble around for something in his bag, no doubt waiting for everyone else to finish changing and leave the room first. You know he wont get changed in the bathroom stall because he always made a big deal whenever someone else did it, making fun of them for probably wanting to hide their tiny dicks. He knows if he did it now, it would bite him in the ass.
After getting changed you linger about again, reveling at Chuck's obvious discomfort. You wait until the last minute before heading to the gym, just in time for your name to be called as the teacher marks attendance.
Coach Gregson reaches the end of roll call as Chuck comes running through the door having finally changed into his gym shorts.
"About time you showed up!" Coach Gregson barks, he was a real hard-ass "All right, today you'll be doing the rope climb!"
The whole class groans.
"SHAADUP!" Coach Gregson roars "CHUCK! Since your the last one here you can be the first one to climb the rope! Get going!"
Chuck mutters under his breath as he starts pulling himself up the rope. The rest of the class are gathered around in a circle watching him. Once he was high enough for everyone to see him you spot your chance.
Standing at the back of the crowd so no one can see, you take out the doll. First you start stretching his hips, ass and thighs wider until...*RIP* A great big gash appears at the seat of Chuck's pants exposing his underwear to everyone below. Small murmurs of amusement can be heard all around but you're just getting started.
Chuck freezes, not sure whether he should cover his ass or keep both hands on the rope. Next you give the doll a little shake. The movement causes Chuck grip onto the rope tightly hoping not to fall.
"AHHH!" he squeals in panic.
"Aww is widdle Chucky scawed?" Coach Gregson teases to the rest of the class's amusement, "You're not even half way up! Quit shaking in your panties and get on with it!"
That gives you an idea. You take out the eyedropper from the voodoo kit and squeeze a few droplets onto the doll's crotch area.
"Look everyone!" yells one of the students "He's peeing his pants!"
You look up and there is indeed a wet patch forming on the front of his shorts before streaming it's way down the rope followed by a collective sound of disgust from the crowd.
Next you tickled his balls causing him to yelp and lose grip with his legs. The class is starts snickering as they watch Chuck hanging on with just his hands.
You squeeze Chuck's hips on the doll causing his waist to return to regular size. Chuck is trying to get his legs back around the rope but now due to his skinnier waist and the added weight of his piss, his struggling causes the stretched and torn shorts and underwear, to slip down around his ankles, exposing his micro-dickie to the entire class. Everyone bursts into laughter as they watch the bully spinning around on the rope with his tiny penis exposed. However he is so distracted trying to hold on that he doesn't even realize that everyone can see his shameful little dick.
"Please!" he begs, "Someone get me down!"
"Stop messing around and get your ass up that rope!" Mr Gregson orders, "I don't want any of your baby dick excuses Chuck!"
Upon hearing that Chuck looks down and finally notices his minuscule cock is out for all to see. His immediate panicked reaction is to reach down to pull his pants back up but then with only one hand on the rope loses his grip and falls landing flat on his ass, splashing on the piss that had puddled onto the padded safety mat.
Meanwhile you pull on the doll's hips and thighs to make them fatter again. Chuck is lying on his back, one hand covering his small cocklet as his other hand struggles to pull his shorts that were moments ago too loose, back up past his thick thighs. All the while your fellow class mates are standing around pointing and laughing making lewd remarks. Knowing he's going to need two hands to get his shorts back on he exposes himself briefly leading to another wave of raucous laughter at the pathetic sight. He finally manages to get himself covered, though the urine had rendered the white fabric transparent. Furthermore the material was still very tight around the groin highlighting a distinct lack of bulge. Chucks face is completely flushed red, tears on his cheeks as he rolls over to scramble off the safety mat.
"In all my years I've never seen someone cry and piss their pants like a little baby but with a dick like yours I'm not surprised." Coach Gregson sneers. "That'll be detention! For showing up late, getting piss all over the equipment and ruining my class. Now get out of my sight!"
Chuck runs off sobbing towards the changing room with both hands covering his pee-pee soaked pee-pee. On the way you tug one of the voodoo doll legs causing him to trip, once again sending another wave of laughter his way.
"All right I don't want your parents on my ass for making you climb a piss soaked rope so I guess you guys can just play basketball for the rest of the lesson." Coach Gregson says, which is followed by cheers from all the students. "Sort yourselves out while I go get the janitor to clean up this mess"
As soon as Coach Gregson leaves the room a few of the students take out their phones and starts texting. You're fairly sure everyone in school will know what happened by lunch time.
