"Alright, Amelia, let's take five!"
The call echoed throughout the large grassy field where just a trainer and his Lopunny stood. The rabbit Pokémon stopped her bouncing and walked over to her trainer, Will. The young man could tell even from afar that she was winded, her brown-furred chest rising and falling rhythmically, her pace much slower than normal and without the usual pep in her step.
"Hm, we may have to cut down on the bouncing exercises some," he said, meeting his Pokémon on her way to him. "I know we need to keep in top form for the Pokéathlon, but there's no need to run you ragged."
Amelia glanced up at him and nodded, still catching her breath. It put a smile on Will's face to see how dedicated she was despite her exhaustion. Ever since he received her as a Buneary in a trade back when he was just a fledgling trainer, she had always been willing to put in one hundred and ten percent into whatever it was he wanted of her. She had to be the most obedient Pokémon he had ever known. He was glad he had her at his side through thick and thin.
While lost in his thoughts, a twinkle of light caught his eyes, drawing them down to the key stone lodged in the Mega Bracelet on his wrist. The Lopunnite affixed to the necklace around her shoulders glinted in the midday sunlight as well. It gave him an idea.
"Hey, how about you practice some while Mega Evolved, huh?" he asked, a shadow of a smirk coming across his face. "Unless you're too tired for it, of course."
Just as he expected, Amelia put on a look of determination and readied herself to Mega Evolve. She was never one to disobey him, especially when he seemed to be let down, which he never was truly. Will lifted his Mega Bracelet above his head and watched as the Lopunnite began to glow bright white and a shell of radiant energy formed around his Pokémon only to crack and burst open with a resounding pulse to reveal Amelia had Mega Evolved.
Amelia let out a happy cry and began to bounce around energetically, all of her fatigue forgotten. Will could hardly keep track of her as she hopped to and fro, somersaulting all around the field like a spinning top. It always amazed him to see how her personality changed when she became a Mega Lopunny; the once subdued, obedient Pokémon was replaced with a restless, even wild ball of energy. She would still take direction from her trainer, of course, but she'd would always have her own way about things, letting loose like she never had as a normal Lopunny. He enjoyed seeing her have so much fun with it, so he could never really begrudge her antics.
She finally came to a rest as she landed gracefully in front of him, smiling from ear to floppy ear. The once drained Pokémon wasn't even breathing hard, to Will's amazement.
"Nice to see you're still as energized as ever, Amelia!" he said, grinning. "That was pretty good already, but I think we should work on some running drills. You can jump with the best of them, but your sprinting needs some work still."
Amelia tapped a finger against her chin, seemingly thinking what he said over. Will almost thought he could see a mischievous light in her eyes as they looked over him, but Amelia turned and took off before he could be certain. The Mega Lopunny was fast indeed, racing away from where her trainer stood and making it across the field in just a few seconds. Her speed was very good, Will knew, but her endurance was a bit lacking he felt. Still, he started to reconsider just how much she'd really need to practice her running as he watched the cloud of dust she left behind whisk away in the breeze.
Lost in his thought, it took a moment for Will to notice Amelia returning to him. Even at the other side of the clearing, he could make out the dirt being kicked up behind her; she was coming in hot, as fast as she could go. He had just enough time to wonder if he should move before the Rabbit Pokémon sprung into the air and flipped head over heals like a rocket through the air just to come crashing into him.
Will blinked slowly, wondering why he was looking up at the sky. The weight on his chest and the badly stifled laughter from the Mega Lopunny atop him brought back his memory. He craned his neck up and glared at Amelia, still trying to clear his head.
"Now was that really necessary?" he asked, grimacing. "You could've really hurt me, you know."
Amelia only chuckled harder, even laughing out loud. Really, Will knew she had remarkable control and would never do anything to hurt him, but he still liked to remind her to be careful on the rare chances where she did something so uncharacteristically reckless. She eventually quit with the laughter and wiped her eyes dry, but she remained where she was on top of him. Will watched as the strange look in her hot pink eyes returned, making him nervous.
"Okay, you've had you're fun," he said with a huff. "How about you go ahead and get off me so we can keep on with the training?"
Amelia did no such thing, smirking with half-lidded eyes down at her trainer while she stayed perfectly still, seated on his lap. It was no use trying to get her off of him; though she was a bit shorter than him and lighter too, he was more than aware of the extreme strength Pokémon could possess, and Amelia was certainly no exception. She would have to move for him to have any hope of getting up. That wasn't going to stop him from letting the idea across physically. He tried to wiggle out from underneath her, shifting his torso and lower body from side to side. The effort was fruitless of course, but it certainly made Will uncomfortably aware of the weight of Amelia's bottom directly on his crotch. He immediately stopped his efforts and tried to force himself to forgot what he just felt.
"C'mon, Amelia!" he said as he propped himself up on his elbows, trying not to sound as nervous as he was. "What are you waiting for?"
It seemed his very words were the answer to his question. She shot her hands down to his chest, pushed his back flat to the grass, and leaned in to kiss him deeply. Will cried out in shock but was muffled by the kiss and unable to do anymore. His mind raced a thousand miles a minute, his heart beat like it was about to burst, his stomach did backflip after backflip. Everything told him what was going on was wrong, so very, very wrong . . . but the soft touch of her lips on his and her warm fuzzy body lying upon him felt simply amazing. They had cuddled back when she was a Buneary, but he had stopped the practice once she evolved into a Lopunny and became particularly voluptuous, even more so when she would Mega Evolve; it was just too awkward for him at that point. He quickly regretted his decision then and there. His breathing went back to normal, and he let himself enjoy the kiss, going so far as to press his lips against hers. It was just a innocent, little kiss between a trainer and his Pokémon, of course, nothing wrong there.
They held the kiss for a long while, and they were still slow to pull apart. Will gazed up at Amelia and saw a little smile on her face and in her eyes, a genuine one, not some teasing display she used to rile him up. He felt his chest tighten to realize it was more than just a simple kiss, much more. Unable to restrain a curling of her lips, Amelia wiggled her hips from side to side, rubbing her bottom across his lap nice and slow. The feeling of tightness suddenly descended to Will's lower regions, making him flush and sweat. Between the touching emotional connection and the arousing embrace they shared, Will could tell his resistance was futile. Some part of him still tried to fight back despite what his heart and his manhood wanted, forcing him to give it one last shot.
"A—alright, that's e—enough!" he stammered in an unconvincing tone. "We n—need to stop thi—"
Amelia had always been quick with her hands. Will didn't catch a thing as she slipped her arms to his waist and pulled down his shorts and boxers, and it was only when he felt the soft, almost ticklish touch of fur and the squeeze of supple flesh around his very erect dick that he realized what had occurred. He locked eyes with his Pokémon, unable to utter a word. Amelia kept his gaze, smiling wide as she began to move her hips up and down, sliding his member between her pillowy buttcheeks. A shudder passed through the trainer underneath her; he couldn't even pretend to himself that it didn't feel like heaven. He had certainly noticed just how bottom-heavy his Lopunny was, but he always made sure to ignore her big, round behind and the hypnotizing way her hips swayed back and forth when she walked. It was even worse when she Mega Evolved. The rest of her body would become nicely toned and defined, yet her butt was instead made perkier and even outright bigger than before, and the way her fur resembled torn pantyhose was icing on the top. It would take everything he had to drag his eyes away from her bottom as it jiggled with every step she'd take.
That old struggle seemed so far away to Will now that his Pokémon was happily stroking his cock. Amelia chuckled to see her trainer bite his lip as she pushed up against his shaft and traveled back and forth along his length. Already, she could feel it throb and twitch at her soft fur and supple, yielding rump. Wanting to take it even further, Amelia stopped for a moment, loosed her hands from around Will's wrists, and sat up.
"Hnng," Will groaned as her warm cheeks surrounded his dick, only the very tip of his member managing to peek out.
A sharp gasp replaced his groan as his Lopunny placed her hands on each side of her rump and pushed them together, squeezing his member tight. His tip sank beneath the bulging fat that pooled around his cock, squishing it all over. The pressure itself made his manhood quiver all the way down to his balls, already close to release just from the warm, silky embrace of Amelia's fat ass. He bit his lip and tried to force it down, wanting to enjoy the moment as long as he could.
Amelia had other plans. Without warning, she started to bounce up and down on his lap, hard and fast, never letting up any of the pressure against his shaft. Soft slaps filled the clearing, drowning out Will's weak moans. Her thick bottom and velvety fur slid along his member quickly, squishing it from the base to his sensitive tip with the perfect amount of friction to leave him tingling at the edge. Will couldn't begin to wrap his head around how it could feel as soft as a pillow and yet firm enough to provide the resistance to his bulging manhood that left him breathless. It didn't take long for his pre-cum to seep out and coat them both, letting them slide against each other with even less effort. Amelia capitalized on it instantly, grinning madly as she pushed her hands deeper into her cheeks and sped up some more. If that wasn't enough, she began to wiggle her hips as she went, not slowing down in the slightest. Her big, fat ass squeezed and swirled all over his cock, assaulting it from every angle with its softness and warmth. Will knew it was time.
He tried to warn her, but he couldn't bring the words to his mouth, couldn't think about anything but the heaven on his lap. He gripped the grass he lay upon, knuckles bone-white. Amelia knew it was coming too, from the way Will's eyes were forced shut and the powerful throbs emanating from his cock. At last, Will managed to gasp sharply, and Amelia felt his cock shudder all along its length as he came. Amelia shivered as a surge of sticky warmth shot in-between her cheeks where his member was completely enveloped. Will instinctively thrust upward lightly, barely able to focus as waves of bliss overwhelmed him. The head of his cock managed to peek out and fire thick ropes all over his Lopunny, throbbing incessantly all the while. Amelia smiled as she continued to work his cock, slipping and swirling against his erupting manhood, relishing the hot flood of cum inundating her bottom and lower back. Her helpful ministrations ensured Will drained his balls as much as possible, riding out his orgasm for a long, long time.
After his last, little throb, Will managed to open his eyes. It took a little while for his eyes to refocus in the bright sunlight, but soon he could make out Amelia beaming down at him. Never had she looked so smug before.
"Alright, that was . . . very nice, Amelia," Will told her, trying his hardest not to look completely wore out. "I guess that'll wrap up training for today. C'mon, get up so we can head back home."
With a nod, his Lopunny jumped up, but not before she made sure to squeeze his softened member extra tight one last time as she slipped her ass off of it, wicking it surprising clean. Will let out a strained grunt, trying not to fall apart at the powerful touch on his overly-sensitive dick. He stood up and picked up his pants, glancing over at Amelia smirking back at him. He could tell this wouldn't be the end of her newfound interest.
"Let's head on home, then."
Amelia turned around and started to walk ahead of Will, letting him see the huge mess he made, her lower back and her entire ass thoroughly glazed with his seed.
"Uh, on second thought," he started, stopping Amelia. "Let's take a dip in the lake right here, huh?"
Amelia giggled playfully as she turned around and raced past him to the waterhole. Will watched her dash on, knowing she did that on purpose.
"Man," he said to himself, following her slowly with a half-smile. "I'm never going to see the end of this . . ."
