Leaking Fuel
Wrote this a few months ago after seeing a design on teefury which is what the image for the thumbnail is from. I couldn't get it out of my head so I wrote most of this during my breaks at work and finished it when I got home, so if it seems rushed that's part of the reason. I also wanted that feel to it because all this is happening as he's running from something.
"Oh god, oh god, oh god!" Rocket frantically muttered to himself as he ran through the forest. Running into a clearing he stopped to catch his breath, listening. "Oh thank god" he said, not hearing anything. He didn't know if he lost his pursuers completely but he hoped it was long enough, as he ran to the nearest tree he could see. Quickly unzipping the lower half of his jumpsuit, whimpering as he pulled out his semi-hard cock and pointed it at the tree just in time.
Pee exploded out of his tip as his head snapped to the side letting out a long sigh, probably a little louder than he should have but the relief just felt so good. Looking back down he took a moment to everything in, the way his stream left him and hit the tree, how his pee bounced back from the force feeling the drops landing on his legs and footpaws, and of course the sound. It all turned him on more than he thought it would but the sound got him the most. As his stream started to weaken he listened to the last of it hit the tree. Once he was done he took a moment to listen again, he still didn't hear anything but he didn't want to stick around more than he had to.
Glancing back down his ears flattened back when he saw his cock was now out of his sheath and rock hard. He knew he shouldn't stick around but he wouldn't be able to run as fast like this, the jumpsuit he was wearing was tight enough without a part of himself restricting his movement even further and the thought he might get caught like this was too much. He no longer had a choice now, he had to do this. As soon as he wrapped his paw around his cock his back instantly arched, letting out a moan as he just barely managed to get his free arm up to stop himself from falling face first into the tree.
It had been far too long since he last did this and being out in the open he was a lot closer than he thought he'd be, the feeling was such a shock that he lost all control as he started thrusting up into his paw. He looked down again watching himself slide in and out of his paw, he longer cared if they caught up to him and saw him like this, he couldn't stop if he wanted to. He closed his eyes, trying to savor the moment, make it last as long as possible but as his mind flashed back to the image of his stream of pee hitting the same tree he was now leaning against, it became too much.
He gave one last thrust into his paw as his eyes snapped open to watch several long thick ropes of his raccoon seed fly out of his cock and land all over the tree. He took several long deep breaths as he waited for his cock to soften enough before putting it back inside his jumpsuit, still leaning against the tree. Zipping himself back up as he walked to the edge of the clearing, he looked back at the tree before running in the same direction he was going. He would definitely have to do that again but hopefully next time he wouldn't be running for his life.
