Maylene and Riolu by Imouto Kitten

Maylene's private Dojo at the Veilstone Gym was filled with the sounds 
of combat as the diminutive Gym Leader sparred with one of her Riolu. It 
was an unusually warm day and the Dojo lacks air conditioning, so the 
pinkette had exchanged her typical attire, already quite light, for a 
short tank top that was little more than a sports bra and a similarly 
skimpy pair of short shorts, and yet she was still drenched in sweat 
from head-to-toe from the workout her partner was giving her.

Despite being more than a head shorter than his trainer and having even 
thinner limbs, the blue and black Jackal was incredibly fast and met 
everyone of Maylene's strikes with equal force. Though panting heavily 
from the heat and the exertion, the Pokemon's fur remained unmatted 
thanks to a lack of sweat glands.

Neither combatant had any idea how long their fight lasted and there was 
no referee to keep track, but when it came to an end, Maylene found 
herself with her back against the floor mat, 45 pounds of canine pokemon 
straddling her exposed midsection, and a tiny Aura Sphere mere inches 
from her face.

Despite the loss, Maylene has a wide grin on her face as she praises her 
Pokemon, "You got me good."

Wagging his tail and using Aura to 'speak' directly to his trainer's 
mind, Riolu asks, "Mistress pleased?" as he lets his imperfect Aura 
Sphere dissipate.

"Very pleased!" Replies Maylene, "I may just use you the next time a 
trainer shows up looking for their third badge." Riolu's tail wags more 
vigorously excited at the prospect of being promoted from his trainer's 
Second Badge team to her third badge Team, but Maylene notices the sign 
of her pokemon becoming excited in another way. "If that red rocket I 
spy is any indicator, I think I know the perfect way of rewarding you 
for your outstanding performance." and indeed, the combination of praise 
from the female he saw as the alpha of his pack coupled with straddling 
her well-toned stomach when she's practically in little more than 
underwear had caused Riolu's bright red cock to emerge from it's sheath. 
and it was now pointing directly at Maylene's face.

Wriggling out from under her pokemon, Maylene gets on her hands and 
knees before reaching back to pull down her shorts to reveal her lack of 
panties and expose her pussy to Riolu and shaking her butt as she says, 
"You've dominated me on the battlefield, now let's see if you can 
satisfy me in the bedroom."

Somewhat confused, Riolu replies, "Mistress want mate me?"

"Yes!" replies Maylene, starting to get impatient. Riolu walks up behind 
her, places his forepaws on her cute little butt and lining up the 
pointed tip of his member with her opening drives himself balls deep 
into his trainer's cunny.

"Mistress tight! Mistress warm!" says Riolu over their aura connection 
as his cock is engulfed by Maylene's pussy.

"That hot, little cock feels pretty good too!" replies Maylene, 
delighted to have a Riolu inside her once more.

Gripping her hips tightly, Riolu starts thrusting into his trainer, the 
pinkette taking the opportunity to practice her kegels as she shouts, 
"YES! Rut me like a little bitch!" Riolu picking up his pace at her 
words.

Maylene is enjoying being fucked by her pokemon, but wants to be further 
dominated, so she reaches her hands behind her, Riolu taking her hint 
and grabbing her wrists and using her arms for extra leverage to fuck 
her harder.

But then something Maylene hadn't planned for happens as Riolu is 
engulfed in a bright light. Maylene gasps as the cock within her starts 
to lengthen, the pointed tip pushing through her cervix, but then that 
innermost portal is pried open and her passage stretched to it's limit 
as the member more than doubles in diameter. At the same time, the grip 
on her wrists tightens and becomes stronger than steel and she's lifted 
further off the mat as her partner's legs elongate.

As the newly evolved Lucario procedes to fuck her harder than any Riolu 
has ever managed, panicked thoughts of 'OH SHIT! OH FUCK! This is bad! 
This is very bad!" race through her mind. Maylene bred and trained Riolu 
and Lucario partly because they were mostly male, Riolu dicks tended to 
be just the right size for her tight, tiny twatty, and as long as they 
were Riolu, they could only shoot blanks, but in addition to the fact 
the Lucario cock she now found herself impaled upon was stretching her 
insides to a rather uncomfortable extent, Lucario belonged to the 
human-like egg group, making them capable of producing offspring with 
humans and Maylene was presently at the most fertile part of her cycle. 
She had rewarded dozens of eager male Riolu with sex once they were 
strong and skilled enough to beat her and the few female Riolu and 
Lucario she raised were usually more than willing to let the male 
Lucario shoot inside them, but this was the first time a Riolu had 
evolved in the middle of fucking the pinkette.

Maylene is snapped out of her thoughts as Lucario, now capable of much 
clearer aura speech, comments, "Mistress Maylene is beautiful. I'm sure 
you will bare strong pups." With those words, the pokemon, now roughly 
the same height as his trainer, loops a forelimb under each of the gym 
leader's legs, letting her shorts fall to the floor as he lifts the girl 
against his furry chest, careful not to stab her with his chest spike.

Starting to enjoy being fucked by the larger than she's used too cock 
ravaging her pussy, it takes all of Maylene's inner focus to shout 
between moans, "Please. Don't. Shoot. Inside. Me!"

Not slowing in the least, Lucario replies through aura, "But I can smell 
it in mistress's scent and feel it in mistress's aura. Your body is at 
the peak of heat and longs for mutual climax with a mate.", and indeed, 
the trainer's body wants nothing more than to cum hard around the 
pokeprick buried in her depths, and she's not sure she'd be able to pull 
off if she was the one in control of this encounter, and even if her 
body would cooperate, there's no way she could break out of Lucario's 
grip.

And yet, Maylene makes another desperate plee, "Please, I'm not ready to 
be a mother!"

"Then why did you offer to mate with me?" Asks Lucario.

"Because Riolu can't get girls pregnant! I didn't think you'd evolve so 
quickly!" cries the panicked girl.

"But it is thanks to Mistress's love that I was able to evolve!" replies 
Lucario, "Please let me show mistress how much I love her!"

Before Maylene can muster further protest, she feels her pussy stretched 
even further as Lucario's knot swells within her and his seed erupts 
straight into the gym leader's womb, but instead of sounds of outrage, 
only sounds of pleasure escape the pinkette as the strongest orgasm of 
her life crashes into her, making her forget about the fact she's being 
flooded with virile semen as euphoria overwhelms her, and she eventually 
passes out from the sensory overload.

###

It is weeks later that a downtrodden Maylene enters her bedroom before 
pulling out the pokeball containing the cause of her sullied mood and 
summoning it's occupant into the physical world.

As Lucario finishes materializing, Maylene informs him of the news she 
got just earlier that day, "I hope you're proud of yourself! I just got 
back from the doctor, and it's official. I'm pregnant, and it's your 
fault, you big, dumb, furry, sexy, horn dog!"

"Mistress Maylene seems... moody." Replies Lucario to his trainer's 
tirade.

"Moody! Is that all you have to say for yourself!" Screams the pinkette, 
falling to her knees and pounding her fists against Lucario's chest, the 
pokemon not even flinching as the gym leader let's out her frustrations. 
She soon tires, her anger giving way to tears as she balls her fists in 
his fur and soaks it with her waterworks, "I'm not ready to be a mother, 
and you wouldn't listen when I told you to stop."

Wrapping his arms around his clearly distraught trainer, sorrow coming 
through his aura speech, Lucario says soothingly, "I'm sorry mistress. I 
didn't think completing the mating would upset you so. Is there anything 
I can do to help?"

There is a long pause with only the sound of Maylene's sobs to break the 
silence before the pinkette, cried out and red eyed looks up to make eye 
contact with her pokemon, "I think...*hic* I think I just need to be 
held in a warm embrace for now."

Careful to avoid stabbing her with his chest spike, Lucario scoops up 
his trainer bridal style and carries her over to the bed. Sitting in 
lotus position with Maylene sprawled accross his lap, Lucario focuses on 
both their auras, trying to project the calm of his own to wash over the 
girl and even out the turmoil he feels in hers.

After some time, Maylene starts to relax in Lucario's arms, snuggling 
into his fur as she does so.

"Does my mistress feel better?" Asks Lucario through the aura connection 
he's established.

Her lips curling into a small smile, Maylene replies, "Much better. 
Thank you." after some time, she adds, "It feels a bit weird for you to 
continue calling me Mistress when we're having a baby together."

"Would you prefer I called you just Maylene?" asks Lucario.

"That'll do for now," replies the pinkette. "You know, I did enjoy 
mating with you. A lot more than the many times I've let a Riolu fuck 
me. Not tonight, but once I've recovered from the shock, I think... I 
think I'd like to mate with you repeatedly until the baby is born."

"I'd be delighted to, Maylene." replies Lucario. After a brief pause, he 
adds, "I...I love you."

Maylene is quiet for a long time before replying, "Ask me again when I'm 
not so mentally and emotionally drained, but I think... I think I love 
you too.", and with those words, Maylene drifts off to sleep in the arms 
of her mate, the Lucario watching protectively over her and their unborn 
child.
