Author's note;
This is a response to a creative prompt on a discord server. It was written with no planning and pretty much made up as I went along. With that in mind, any feedback is appreciated.
Prompt; "Prior to getting together, who had a massive collection of pictures of the other boy stashed in their porn folder?"
Jack knew what we was doing was wrong. He knew that if he got caught doing it, he would be expelled and possibly busted by the police but he couldn't help it. What's more, he didn't care. Hiccup is hot and he needs as many pictures of his naked body as possible.
There was only one shower in the High school's changing room was occupied, that had to be hiccup. Jack switched his phone to silent and snuck into the shower in the shall next to the one in use.
As he locked the door he stood up on the small bench they had for putting your bags on them. He could hear the water splashing in the next shower and tentatively peered over, just enough to see Hiccup's hair. Once Jack was confident it was hiccup, and that Hiccup was looking down, he set his phone to burst photography mode and held it over the top.
His phone snapped several pictures in the space of a few seconds. When it vibrated to say it was done with taking pictures he pulled his hand back and looked at what he had got. Some of them were useless and showed nothing. Others were Golden. When Hiccup moved around the right way he could see his whole front. Jack blinked a few times in amazement to when he saw Hiccup was hard. "Wow. He's quite a big boy" he thought.
His ears picked up on something. The splashing sounded different and he could hear Hiccup grunting quietly. "Is he...is he masturbating in there?!" Jack thought. His own dick immediately starting to get hard.
Jack had a flash of inspiration. He opened up Bambuser. He was going to record what was happening but he didn't want to risk running out of memory and losing the lot. This way he could save it in the cloud as long as the battery held up.
He set the broadcast to "Private" and hit the "Broadcast now" button before holding his phone over the top of the wall again.
Jack couldn't see what was happening but he could hear a few key sounds so let his imagination fill in the blanks. Hiccup pressing against his bladder with his left hand and quickly stroking with his right. The soapy water making a good enough lubricant that Hiccup quickly started to lose control of his body.
Jack felt the stall wall shift slightly as Hiccup leaned up against it. His breath getting shorter and his grunts getting louder. He was clearly trying to control the volume of the noises he was making. Maybe he knew he wasn't alone in there. Hopefully he had no idea he was being filmed.
Jack heard Hiccup let out a set of rhythmic grunts. The wall shaking and whilst whole body jerked. Jack still couldn't see what was happening but he knew Hiccup had just hit his orgasm. He could hear the sound of relief in his moans.
"WHAT THE HELL?!" Hiccup yelled
"OH SHIT!" jack thought. He must have looked up and seen the phone. Jack unlocked the door and bolted for the exit. He hoped Hiccup wouldn't dare come out naked to find out who had been filming him and thankfully he was right. He was out of the changing rooms before he heard the stall door open. He sprinted down the corridor and out of a side-exit of the building. The adrenaline coursing through his body he simply kept running around the side of the building to the main carpark and the break time tarmac.
Jack stopped once he felt safe. He tried to look at his phone to stop the recording but his hands were shaking too much from excitement and adrenaline. He eventually managed to stop the recording. He would have to wait until he got home to download it, be he was defiantly going to add that one to his personal collection. Now he had to go find a place to take care of his own erection.
