Josh sat drinking his Coke, swinging his legs under the table like any normal 10 year old, except thanks to Jake's watch he wasn't exactly normal.
"Gotta pee!" Josh jumped off the seat and headed back to the toilets, his Mom confused as he'd literally just been.
Jake meanwhile was frantically patting his pockets. "Shit my keys" he muttered heading back to the toilets behind Josh.
Josh was stood at the urinal as Jake walked in, the bathroom was very badly designed as you could see anyone's junk as soon as you walked in and Jake got an eyeful. Stood in front of him was a short kid with a python of a cock in both hands, his piss streaming, almost thundering into the trough. Josh looked over and saw 'tiny' enter and smirked to himself. Thinking to himself "Fucking loser with such a tiny cock, this is what a man has between his legs." Bursting with pride he shook the remaining piss from his huge cock, maybe shaking it a little more than needed, feeling Jake's eyes on him.
"Come back for another look then tiny?"
"Wha... what no, don't be sick you're just a little kid!"
Josh laughed at him, not even bothering to put his cock away, letting it hang there for all to see. All being Jake in this case. "Dude I'm like 2 years younger than you and this..." he grabbed his slightly plumped up cock and shook it again, "... makes me more of a man than you." Jake just stared, feeling himself hate this kid all the more, his inch prick suddenly hard. Slowly Josh ran his hand from the base of his cock all the way to the end and back. It must have gained a least two inches there, still hanging downwards but firmer, his small hand unable to grasp all the way around it.
"Anyway dude, how sick are you? Stood there watching me pee!" He laughed again and gave his cock another slow stroke. It gained some more length, easily passed 16 inches, thick with veins running up the smooth, pink skin, his balls hanging over his waistband, each the size of a apple.
"You stopped... peeing a while ago now you're... you're just showing off..." Jake was almost whispering, his cock harder than he thought possible.
"Damn straight! Wouldn't you with this." Another long stroke, this time he must have been fully hard, it stood out away from him, at least 25 inches in length and a glob of precum formed on the end. "You wish you had this, am I right? Wish you could stroke this?" He held it in both hands, neither able to fully grasp around it, probably neither ever would. "I mean I can't exactly put this back in my pants now can I tiny?"
Jake started to shuffle forward, Josh nodded and smiled.
