DISCLAIMER: This is a work of (fucked up and sleep deprived) fantasy. This also contains w/s, and teen sex. So uhh, if you're in a country that doesn't like this kinda stuff then don't read this.
Josh knew he should've avoided drinking so much today, his bladder was plump. Filling to the brim of desperation. He knew his 13 year old body could take it, but not forever. Even though he had previously been able to play it safe with drinking two liter bottles every day, he didn't think about the reality where he wouldn't have a safe outlet for all that fresh piss. He was in an exam when the spell struck hard on him.
He tried his best not to bother anyone else, since he had finished the exam in a fast and efficient manner. He'd have to wait another twenty minutes before he could relieve himself. He'd personally trained his bladder since he was quite hard to toilet train. As time passed, he could feel the piss slowly going through his 4 inch penis that was getting erect to an impressive 5.5 inches from all the desperation.
"Ten minutes, that's fine. I'm a big boy, I can take it for a bit longer." he thought to himself.
Squeezing his knob was keeping the tide at bay, but knew that he'd have to release it some time soon. Once there was a minute remaining, he knew that the tension was going to be extreme. He worried that the bathrooms would be closed and he'd have to hold his aching bladder until he got home. Though unfortunately for him the bathrooms were indeed closed and Josh had to improvise.
He had snuck onto the field where nobody would see him and whipped out his throbbing cock and a bottle. He'd wanted to see just how much he'd be able to hold. His record was 800ml but he knew that he was holding a load much heavier than that. It was one of the two liter bottles, and he'd hope to fill it. He barely managed to aim his piss into the bottle as a torrent of piss hit the bottle and began filling the bottle up.
He had felt such great relief just even making it this far. He pissed a river, a thick heavy stream shot out. He was concerned he'd fill the bottle at the rate he was going. It was only a minute before he had filled the bottle half way. Seeing that gave him electric shocks in his body. He had just a bit more to push out, squeezing the last bit of piss in another minute. 1.6 liters.
It felt so heavy in his hands. He was trembling with ecstasy, his dick was rock hard from the ordeal. He looked around to make sure nobody was there still. After seeing that nobody was around, he thought about the grant pleasure he felt holding in that much piss. His already hard cock was leaking a bit of precum.
He started thinking about one of his best friends stopping him from going, prolonging his bladder from leaking. His cock rumbled with spasmodic vigor as he masturbated, not a care in his world as to what he was actually doing. It wasn't long until he felt the cum raise from his balls and spurt out like a fountain. It was the biggest load he'd ever shot. Volley after volley of semen flew out of his dick while he experienced pure tranquility. After finally snapping out of it, he suddenly noticed that one of his friends was staring at him.
He noticed the bottle of warm piss, and stated,
"I knew you'd be out here after the exams, I saw you grabbing your junk like you were about to get kicked in the nuts!"
Josh blushed in embarrassment,
"D-d-don't tell anyone about this! I usually have a plan for when I do this but today was just not a good day to do it, Max!"
"Don't worry, I actually enjoyed the whole thing. As you can see."
Max had a noticeable bulge for a 14 year old.
"You're such a faggot, Josh. Not giving me a nice bottle to use."
Max whipped out his throbbing 6 inch dick with a fair bit of precum dripping from it. He started to take a piss right in front of Josh. Josh tried to drink from Max's dick as he was flushing out his bladder. The taste was mythical to Josh as he struggled to keep up with Max's torrent of urine.
He went on for 45 seconds before finally slowing down to a dribble.
"Fuck, I needed that." Max muttered
Josh moved his head away from Max's dick but found that he had his head against Max's pelvis.
"What, you thought I was gonna let you go scoff free? Just suck me off and you won't have to worry about your little secret, okay?"
Josh nodded as he tried his best to give Max a satisfying blowjob, and boy was he enjoying it. Max thrusted himself into Josh's head repeatedly as Josh gleefully took all 6 inches of Max's cock. Soon too did Max cum into Josh's mouth. Forcing him to swallow his load.
After Josh recovered from his first blowjob, he muttered,
"So you promise you won't tell about what happened, Max?"
Max sighed and replied,
"A deal is a deal, you're free. Perhaps would you want to be something more than a friend?"
Josh gave an accepting nod and laughed.
"I knew you had something for me."
