It was a nice, hot day in the volcanic region of Pokemon Island. The various fire-type pokemon sat enjoying the natural hot springs and lava pools. Everyone ws perfectly content. Everyone except Arcanine.
    The various parts of the volcanic region were ruled by the most powerful pokemon in those areas. The large fire-dog pokemon was the undisputed ruler of the eastern lava pools, and usually that was enough for him. But today, Arcanine needed something else. He needed to fuck.
    Arcanine knew all he needed was to ask, and any of the female Growlithe that lived around the lava pools would happily let him mount them, but he didn't want a Growlithe. He wanted something closer to his size. Leaving one of the older male Growlithe to hold down the fort, Arcanine explained that he was off to take a long run, to stretch his legs. As the pokemon bounded over the rocks, however, it wasn't just his legs that was being extended. Though it was hidden by his thick fur and tail, Arcanine could feel his large cock bobbing between his hind legs. Something his size. What around here was his size? A charizard lived nearby, but that was the only pokemon around that was bigger than him. He looked out across the volcanic scene from a high rock. Charmander and vulpix played happily together. Magmar sparred, blasting flames at one another in shows of power. These pokemon were all too small for him; most of his Growlithe were bigger than them.
    Arcanine bounded over a few more rocks until he crested a ridge. then he saw them: a whole herd of Ponyta. Arcanine's cock jumped at the sight of their large bodies. Surely they were each as big as him, at least in height. As he watched them run about, however, hed questioned their stability. Yes, he could mount them, but could they support his weight? He was, after all, a very heavy pokemon. He certainly didn't want to injure any of them, for fear of starting a turf war with their herd. Then, beginning to turn away, disappointed, he saw a small hot spring on the other side of some tall rocks, out of sight of the Ponyta. Standing there, her elegant head bent low to graze on the fresh volcanic grass by the spring, was Rapidash, leader of the Ponyta herd. Arcanine's heart leapt. No doubt Rapidash's more powerful form could support his weight!
    Still, Arcanine knew better than to simply run down an mount her. If he were to try to rape the leader of the Ponyta, she would call to her nearby herd. He would likely be trmpled to death and war would surely follow for his Growlithe subjects. He would need to be careful... Arcanine made his way slowly down the rocks, trying not to draw the attention of the Rapidash. She didn't seem to notice him. Soon, he had come within a respectable distance of her, and he stood up on a rock across the spring from the powerful female. Finally, Rapidash realized he was there, and gave a start. She backed away, lowering her horn threateningly. She seemed ready to fight.
    "Wait," said Arcanine, desperate to start on friendly terms with her, "I'm not here to fight, Rapidash. I just want to talk to you."
    Rapidash didn't move or lower her guard. "Why should I believe that?" she asked.
    "If you are only going to react violently to me, then I'll go," Arcnine replied. "I swear I just want to talk."
    Rapidash's head lifted slightly. "Then talk," she said. For some reason, she seemed unusually defensive.
    "I was just out for a run when I noticed you down here," Arcanine said. Though this was technically true, he knew he had lied when he said he only wanted to talk to her, and that gave him a pang of guilt. As he tried to sweet-talk the equine pokemon, he couldn't help but feel a little guilty. She was so big, strong, and beautiful, and he felt like he was trying to take advantage of her.
    "Our respective territories have been under some tough times lately, what with the shortage of food and the Magmar getting more pussy-er-pushy every day." Arcanine bit his toungue and looked at Rapidash's face. Had she caught the slip? Her face had changed from defensive anger to a sort of confused look. "A-anyway," Arcanine continued, not wanting her to think too much about what he had slipped, "I think it would likely be in the best interest of both of us if a union were to form between our subjects..." As he talked, Arcanine's nose twitched. The wind picked up just slightly, and he caught a whiff of someting strange. Whatever it was, he had never smelled it before, and it was beginning to distract him. Also, to Arcanine's surprise, it was also making him more aroused. As he paused after a lengthy ramble about volcano politics, he inhaled through his nose, taking in a better smell of the scent. So sweet, so alluring, so similar to the smell he got from... He suddenly realized what it was. Rapidash was in heat! It seemed he was not the only pokemon in need today.
    As he continued to talk, Arcanine stepped down off the rock on which he stood and began to walk slowly around toward Raidash. As he moved, she shifted unfomfortably and stepped in the same direction around the pool, keeping away from him. Arcanine decided it was time to play his hand. Pausing in his speech, the dog pokemon stopped, yawned, and made a big deal about stretching his legs. First one back leg, then the other. As the second leg, the one closer to Rapidash, stretched out behind him, it left Arcanine's erect member wide open and exposed for the female horse to see. Rapidash saw the large, rock hard shaft and froze. Her eyes didn't leave his member until it was once more out of sight behind his lowered leg.
    Arcanine saw the facination and want in her eyes, but pretended not to notice. He continued around the spring and this time she did not move away. Time to go in for the kill, he thought. "Surely," He said, "there is some way I might prove my sincerity in my desire for peace between us?"
    Rapidash looked into his eyes, and he into hers. Now they both knew what the other wanted. After a few silent moments, Rapidash said, "Very well, Arcanine. I will accept your alliance on one condition." Arcanine raised his head. This was it... "You must mate with me," she said. Arcanine opened his mouth to speak, but Rapidash cut him off. "Also, you must swear yourself to me as a mate. You must never have any other female but myself."
    Arcanine thought this was a peculiar request. He enjoyed his freedom, and usually that might have been a deal breaker, but at that moment, the proviso seemed agreeable. "Agreed," he said to her, "I will mate only with you, and our people will join together to keep the volcano region secure and peaceful."
    Satisfied, and unable to contain her heat any longer, Rapidash turned away and raised her burning tail. She looked back at the male, silently inviting him over. Arcanine spoke no more. Enough words had been spoken; it was time to fuck! Arcanine padded up behind Rapidash and stuck his nose beneath her tail. He inhaled deeply, taking in the scent of the female he had just sworn himself to. He almost collapsed with pleasure at the smell of her arousal. Gathering himself, Arcanine reared up and placed his heavy forepaws on Rapidash's flanks. As he had predicted, she had no trouble supporting his weight. He moved his lower regions foreward until his cock touched the hot, wet folds of her cunt. He looked to the female for final confirmation. She nodded, and without further delay, Arcanine thrust foreward, spearing her sex with his shaft. Rapidash bit her lip to keep from letting out a cry that would bring one of her followers as she was taken by the large male. She moaned softly as Arcanine began a strong, repetitive rythm of thrusts, each thrust accompanied by a low, short growl from the firey dog.
    Arcanine was in heaven. His cock was surrounded by a fiercely pleasureful heat as he humped with increasing fervor into the female beneath him. If every time was as pleasurable as this, Arcanine had no problem at all restricting himself to just one mate. Soon, he was pounding Rapidash's snatch as hard as he could, growling with pleasure. It was all Rapidash could do not to scream out in ecstasy with each thrust. After a few minutes of hard, hot fucking, Arcanine growled loudly and exploded into his new mate. When she felt the hot, sticky liquid fill up her passage, Rapidash couldn't hold out any longer. She let out a loud whinny and came around the shaft, squeezing every drop out of its depths.
    Arcanine was still in a blissful state from the orgasm, but he was still aware of his surroundings enough to realize he should move. He quickly removed his receeding shaft from Rapidash's folds and dismounted her. Not a second later, A trio of male Ponyta came around the rocks. "Miss Rapidash!" one of the Ponyta called to her, "Are you alright? We heard noises." The horse pokemon looked with suspicion at Arcanine.
    Rapidash quickly regained her composure, facing her followers and holding her head high in regal fashion. "All is well," she replied, only the slightest tremor in her voice, "Arcanine and I were just coming to an arrangement. Please return to your business." She hoped they didn't notice the trickle of white that was slowly making its way down her rear leg. After just a moment, the Ponyta disappeared back around the rocks. The second they had left, Rapidash felt something warm and wet run up her leg, wiping away the trail of semen that had leaked out from her sex. Arcanine licked his seed clean off of her, even lapping briefly at her pussy to make sure no more leakage occured, which caused Rapidash to shudder.
    "I'm very glad we came to this arrangement," Arcanine said.
    "We all must do what we can," Rapidash replied with a smile, "for the sake of peace."
