Disclaimer, I did not come up with this. It's a comic I found while I was um... well anyway! This is my first attempt at a lemon (And didn't even make the story) so please so easy on me.

It had been a long and tedious journey for Eevee. Eevee had left his home as soon as the elder had told him he was ready to evolve. Eevee had known since he was very young that he wanted to be a Jolteon. Now he was on his way to find his thunder stone.

One problem, he didn't know how to get one. He didn't want to be captured by a trainer, and he didn't know where a thunder stone would appear in nature.

This left Eevee wondering the streets of a dirt covered town. Eevee was beginning to feel hopeless when he spotted a Ninetales. All pokemon knew of the wisdom of the Ninetales.

Eevee approached the alley where the Ninetales stood cautiously, not wanting to inadvertently offend him. As he got closer, Eevee saw the purple socks, purple bow, and collar the Ninetales was wearing. It seemed odd, but Ninetales had their ways.

"Excuse me sir? Do you know where I could find a thunder stone?" Eevee asked the Ninetales. The Ninetales' face lit up when he saw Eevee.

"Oh I could tell you... for a small price of course." Ninetales purred. "I'll do anything!" Eevee said.

Ninetales grinned, "Then follow me."

Ninetales lead Eevee down into a darker part of the alleyway. "Many eevee have come to me, seeking information on their respective method of evolution. In order to find your stone, you must find Jolteon. Now, I cannot tell you where Jolteon is, but I can tell you where to find one of his brothers or sisters. They in turn will tell you where to find the next brother and sister and, after you've met with all of them, you will meet with Jolteon. It'll be like a quest." Ninetales explained, exciting Eevee.

"But before I tell you where to go, I require a certain payment." Ninetales said with what Eevee registered as hunger in his eyes.
"What's the payment?" Eevee said hesitantly. Ninetales grinned, "Turn around." He said simply.
Eevee was cautious at first, but remembered that a Ninetales always had a rhyme and reason to its actions.
Eevee turned around. "Lift your tail." Ninetales said, his voice filling with anticipation. Obediently, Eevee lifted his tail. Eevee tensed as he felt Ninetales grip his shoulders with his front paws.

"Brace yourself." Ninetales said, chuckling slightly. With no more warning than that, Ninetales pushed his cock into Eevee's ass.
Eevee let out a startled cry at the sudden pain. Eevee, never really knowing much about things like this, was baffled by the intense heat and hardness of the rod pushing in and out of him. The pain was horrible, due both to the fact that this was Eevee's first time and the fact that Eevee had tensed up so much.
"Shut up," Ninetales grunted as he thrust in and out of Eevee, "you want to know how to get your thunder stone right?"
"Y-yes sir." Eevee managed to squeak.
Eevee briefly questioned if the Ninetales was really as wise a being as he had thought. But Eevee's respect for the pokemon was ingrained into him. There has to be some sort of hidden meaning to this, Eevee knew it. In fact, knowing that Ninetales were very skilled in manipulating the mind, Eevee considered it was possible that this wasn't even happening; just a test conjured by the Ninetales.
This was not the case, Ninetales was in fact pumping in and out of Eevee with increasing force and speed, but what Eevee didn't know wouldn't hurt him.
With his mind reassured, Eevee relaxed his muscles. Sensing this, Ninetales reached around Eevee's body, pulling his closer with his socked limb.
Ninetales pushed in and out of Eevee as fast and hard as possible, not particularly caring if Eevee was enjoying it or not. After twenty minutes, Ninetales' body began to shake. He thrust one into Eevee one last time before cumming in Eevee's ass.
Eevee flinched at the heat of the sticky seed seeping out of his rear. Ninetales grinned at the expression on Eevee's face.
"You have done well. As promised, I will tell you where to go."
