The Weavile was randomly strolling through the forest, bored out of his mind. Life didn't offer much excitement since he came down from the mountain. Food was certainly a lot more plentiful down here, and having to run for his life was a much rarer ocurrence. He had settled into a pattern. Eat, sleep, hide from those damned kids with their infernal pokeballs... he needed a distraction badly.

Suddenly, he noticed something pink moving behind a tree. He carefully came closer. One could never be too careful. In this world, there always was the possibility of accidentally bumping into a Beartic that seemed to have materialized out of thin air. As awesome as he was, some things still could give him a lot of trouble. Carefully sneaking from tree to tree, he finally came close and poked his head out.

"Oh, Arceus! What a sight!", he thought. A young female Sylveon was sitting under the tree, and using those feelers or whatever they were to touch herself. Female. Sylveon. Few things were rarer than that. Sylveons were an extremely rare sight already, and he only had seen a trainer use a male one before, from afar. A Sylveon in the wild was extremely unusual. An Eevee needed to be extremely happy to evolve into a Sylveon, and it was very hard for that to happen in the wild. The vast majority belonged to trainers, who almost never released them. And females were extremely rare too. Arceus must have liked to fuck with people. How could something this pink, slender and pretty be almost always male?

She was beautiful. That slender body, those little breasts, the slit glistening with moisture, that expression of utter bliss... all his blood seemed to be going to his nether regions, and all his instincts screamed at him to fuck her right this minute. The last vestiges of his rational mind realized it wasn't a good idea. He'd seen that one Sylveon in battle. They might look delicate, but it turned out they were surprisingly resilient and wielded a terrifying amount of power. If this went wrong, she could splatter his entrails all over the forest with no effort at all. And yet, that always was a possibility. Many lives ended by just bumping into the wrong pokemon by accident. At least if he managed this, he could die happy.

Rationality lost the battle to lust, and with a scream of "YOLO!" he jumped out of hiding right at her. She was so lost in her pleasure that she just stared at him with a blank expression, unable to comprehend what was happening. He landed right on top, throwing her to the ground. Wasting no time, he shoved his dick into her already well lubricated pussy, pinned her to the ground, and started thrusting with abandon.

He was in heaven. She was incredibly tight, which was unsurprising, as she looked very young. He wasn't going to complain though. Such an opportunity couldn't be wasted, and she was in no way innocent with what she'd been doing when he showed up. It was obvious that she wanted to be fucked by a real male, and he'd show her how it was done. With his left hand, he carefully fondled her breast. Claws were awesome for fighting, but he had to be very careful when a delicate touch was needed. It wouldn't be right to harm such a beauty. 
 
The Sylveon under him was slowly realizing what was going on, and started weakly struggling, but her physical strength was no match for his own. Tears welled up in her beautiful blue eyes. "Oh well, it seemed like things weren't going to work out", the thought. Maybe she'd reconsider afterwards?

He came disappointingly quickly. It was unfortunate that he had to rush things so much, but he just couldn't restrain himself. He pulled out and flopped on the ground. He felt exhausted and deliriously happy. He actually had done it! Oh, his friends would be green with envy. This would be the stuff of legends. He looked at her with a smug smile. She was still sitting on the ground, trying to gather her wits, with a large amount of cum dripping from her slit. He idly wondered if she was going to get pregnant after this.

"Hey baby! How did you like that? Want to have another go at it?" he asked, still breathing heavily.

Something inside her seemed to snap at that moment. Her expression changed to pure, undiluted rage in an instant. She stood up. "I'll kill you!" she screamed, all her fur standing on end.

He jumped to his feet and ran like hell. He could feel power gathering not far behind him with a terrifying high pitched noise. "Ohshitohshitohshit" he muttered while darting from tree to tree, desperately hoping there was no straight path between them. If that thing hit him, he was done for. Fortunately, the distance seemed to be increasing. A large shimmering ball of energy impacted a tree right next to him, showering the forest floor with splinters and carving an impressive hole in it. A scream full of rage and frustration sounded just a fraction of a second later, and he realized that she wasn't as far behind as he thought. He had to run faster. 

He arrived at this usual hangout completely exhausted, covered in scratches and with random leaves sticking out of his fur. A few of his friends were there.

"What the hell happened to you?" asked one.

"I fucked a Sylveon right in the pussy!" he proudly declared. Then his knees buckled and he fell face first into the ground.
