“And again!”

The ace trainer’s pokemon skirted across the battlefield, each one fierce and powerful. Her Arcanine, a proud and dangerous battler, was licking flames at the training dummy, and her other pokemon, a huge and lumbering Aggron, rumbled up a growl in his chest as he prepared to unleash his fury against his opponent.

Her heart rising in her chest, the ace trainer felt excitement coming on. This was it. This was it! Her pokemon would pull it off this time!

But then, the exact moment the Aggron sent a crash of stones at the adversary, her Arcanine unleashed a ferocious plume of fire. The two attacks collided on the way, the rocks absorbing most of the heat and blackening. They smashed into the earth, quite short of the training dummy.

The trainer ran her fingers through her hair angrily, trying to keep her patience. She had to be calm. Yelling at her pokemon wouldn’t solve anything, would it?

The issue with this particular hiccup was obvious. Her Arcanine had unleashed her own attack too early. She wandered over to check on her. “What’s the matter, girl?” she asked.

In response, the titanic Fire-type pawed at the ground, chuffing. The ace trainer waved over her Aggron, hoping to talk them through her strategies, but when her Arcanine growled at him, she allowed him to back off.

She sighed to herself. Her Aggron and her Arcanine were two of her most powerful pokemon, and she had hoped to develop them into a complementary pair of fighters to use in double battles. But though each one was individually mighty, getting them to work together was like trying to convince Slakoth to race in a hundred-yard dash!

“All right,” she said, “why don’t we try practicing timing again? Okay, girl, why don’t you attack that enemy dummy on the count of three?” She stepped back, giving her Arcanine a wide berth. She could see her Aggron watching from a distance as well. It’s simple, she thought. She can handle this.

“One…” she said. “Two—”

Pawing the soil with impatience, the Arcanine jetted off a burst of flame early. As the ace trainer deflated, her exhaustion and frustration palpable, the canine pokemon growled, running errantly across the battlefield. Something was up with her pokemon, but she just wasn’t sure!

She shook her head. She knew there was little point in continuing; that today’s training was a lost cause was obvious to her. “Let’s just… shelve this for now,” she said, stepping away with frustration. The Aggron eyed his trainer with sympathy as his compatriot kept acting curious and distracted.

The ace leaned back in her chair, groaning. After the disastrous double battle training session earlier that day, she’d spent the rest of her time working on another teammate instead: her Charizard. He was a powerful pokemon, a battler among battlers, and he’d performed admirably under her directions.

“Good job!” she’d congratulated him when they were done. “You did so well!” He’d responded by nuzzling close, his breath hot on her chest, licking at her neck and cheek. She’d laughed at that; he’d always been so affectionate, ever since he was just a small Charmander. She’d finally had to gently swat him away to get him to give her time to work.

She’d left the rest of her team to their own devices. Her Aggron had lumbered about, his sturdy Steel-type body creaking in the air. She had no idea what her Arcanine was doing with herself.

Taking it on herself to find them, the ace trainer wandered out into the darkening evening. The sun had set and the light was quickly greying, growing cool as the night came on. She frowned. Usually, her pokemon stayed close by to her place—so where could they be? She had a modest house out in the countryside (the better to let her pokemon practice combat) but she still wasn’t sure where to look.

It was her nose that led the way. There was a curious sort of scent in the air, one that seemed familiar. It was a scent of the forest, of the earth, of the wind; of power, might, and battle. A pokemon smell. She followed it, the tangy scent picking up in strength as she searched more and more, until she finally rounded the wall of the sturdily-built stable where her pokemon sometimes ate and slept.

There behind the stable, digging her claws against the heavy bark of a tree, was her Arcanine.

The poor pokemon looked even more worked up than she had been earlier; a small whine, so faint that the ace trainer could barely hear it, rippled its way out of her maw. Her eyes seemed unfocused and distracted, and the way she held herself bespoke to a thorough, unsatiated need. As the Arcanine stopped digging her claws against the bark and paced away, panting, she showed her backside to her trainer—and everything instantly clicked. The dog pokemon’s pussy was swollen with arousal, the lips flushed and puffy. Juices were slicking up the entrance, and a small stripe of pink was present slightly between the outer lips of her folds. At once, the Arcanine’s trainer realized exactly what was going on.

“She’s in heat,” she said, realization dawning. She had a thorough understanding of each of her pokemon’s mating and breeding cycles, and her Arcanine’s heat wasn’t supposed to start for nearly two weeks—but nature wasn’t clockwork. Sometimes cycles started early, and it seemed that today, her pokemon’s estrous had just decided to get the jump on both of them.

Still hiding, she started coming up with possibilities to sate it. Her neighbor, who had the Rapidash she usually paired her Arcanine with, had left with his pokemon for a trip and wouldn’t be back for some days. There was always medicine to suppress it, but she had never given it to her pokemon before, and wasn’t sure if she wanted to risk it while she was still training.

Any more thought was cut off by another sound falling on her ears: a series of heavy, regular footsteps. Her Aggron trudged out of the dark, eying her Arcanine with an inquiring gaze. The ace cursed—the two of them didn’t really get along at the best of times (something her training was meant to rectify) and she was worried that resentment for today’s botched training along with her Arcanine getting worked up might cause a fight.

But before she could step out and recall them, Arcanine surprised both her trainer and her fellow pokemon by turning and, with a needy whine, presenting herself to him. The Aggron seemed taken aback, a sentiment shared by their trainer. They weren’t even in the same egg group!

But actually, she thought, that would be for the better. There’d be no risk of pregnancy…

Her Aggron, it seemed, wasn’t exactly averse to the idea. Though he still seemed surprised, his trainer could, from her vantage point, spy his crimson cock starting to poke out of its sheath. His rod—normally protected behind layers of thick plating—was enormous, incredibly thick, almost tubular, with a broad, flat tip like that of a stallion. His own arousal mixed into the air, threading in with the Arcanine’s, and the mixture was a heady, oppressive musk of raw, animalistic need.

Almost without realizing it, the ace trainer swallowed. The scents her pokemon were giving off… she never would have admitted it to another person, but they were having a certain, uh, effect on her own physiology…
