(Ketchum Household, Battle Room)
A battle had taken place earlier between Ash and the Kalos League Champion: Diantha, damage already taken place on the battlefield, his Lucario and her Gardevoir in their mega forms. However, the psychic Pokemon turned back into their normal form and collapsed shortly after.
"Gardevoir is unable to battle. The winner of this battle is Ash Ketchum and Lucario." Dawn called out as the Grand Duchess went to her fallen Pokemon.
"Are you okay, Gardevoir?" Diantha asked, getting a nod in return.
"Good job, Lucario." Ash says while walking down to his Pokemon who turned back to normal form.
Diantha had come over to visit just like Cynthia did, to challenge the World Champion to a battle to test if she had a chance against him. Of course, she figured she was gonna lose, but that didn't stop her from wanting to test his strength. Things weren't very eventful after the fight... until nighttime that was.
(Later that night)
Diantha was awake and in thought. Before she arrived there, she heard about the recent news about the World Champion not just marrying the Sinnoh League Champion, but also a professor and doctor from Unova who were already married to each other. It came as a surprise to most that they would go for someone that much younger than them, although it got her thinking of something herself.
After she had left the room, her Gardevoir left her Pokeball. Checking to make sure her trainer was gone, she left without being noticed. The psychic Pokemon ran into the Pokemon Master's Lucario who also just so happened to be wandering around as well. The jackal rose a brow before Gardevoir put a hand on her cheek.
The Kalos Champion was only going for a nightly walk around the mansion, not planning to anything more than that. However, that was stopped when she saw the door to the family bathroom open up and steam pour out of it.
And so, the Pokemon Master walked out while sighing, done drying his hair and holding a towel in his hand with another around his waist. He immediately stopped when he noticed the woman.
"Oh, Diantha. I didn't think you were still awake." He says casually.
She didn't answer, staring right at his fit and athletic body with a red tint spread across her face. He stared back, noticing her body through her night gown and the same thing happened to him while also awaking a certain friend under the towel.
(Later)
It happened so fast. Diantha found herself completely nude on the shower floor with Ash french kissing and fingering her entrance. She had her hand stroking his shaft as she was trying to fight with her tongue back, but his easily overpowered hers.
"Oh god." Diantha moaned after pulling away.
"Feel good?" Ash asked as she nodded. "Then you're gonna like this next part. ~"
He then went down and started licking her entrance, causing her to gasp and moan as he did. She rested her legs on his shoulders while he lapped at her folds, getting a taste of her juices and sending a wave of pleasure through her body.
Diantha held his head in place while leaning back against the floor, feeling her face and body heating up with each lick. Her body completely soaked from head to toe from the water raining down on their bodies. He furiously moved his tongue inside of her folds, making sure to taste every bit of it.
After a bit, they changed positions, her being on top of him sucking and stroking his shaft while he was licking at her entrance. She couldn't get the whole thing into her mouth, but she was still putting in her best effort. Unfortunately, she wasn't able to match with the Pokemon Master.
'So big.' She thought to herself, still sucking.
Ash gave her ass a slap while pressing more of his mouth against her folds, licking every bit of her inner walls. Diantha had climaxed from what he did, causing her to stop for a moment as the world champion swallowed each drop. She pulled off of his member and panted for a moment.
(Some more time later)
"I wasn't expecting you to be eager to do this." Diantha says while lying on her back, legs spread.
"It's easy to get used to." Ash says as he was rubbing his member against her folds. " I learned to accept it."
"Will you stop teasing me already?"
He shrugged before he pushed into her entrance, causing her to gasp before gritting her teeth in pain. They took a moment for her to adjust before he started bucking his hips, her struggling to keep her moans in.
Ash was hardly thinking about how tight she was, being used to it already. He reached down, putting his hands under her thighs and cupping her ass, making it easier to keep in pace without trouble.
"Still feel good?" He asked her.
"Yes... just mph... so big."
"It gets easier after the first time."
Ash took one of her breasts into his mouth and started sucking on it, which eased her slightly. That didn't stop her from climaxing on his shower floor. They continued like this for a little bit before the world champion felt his member starting to twitch.
"I'm gonna cum. If you want it inside-" He says before Diantha wrapped her arms around him and pulled him into a hug, locking her legs around his.
He got the hint and sped up his hips. He would soon blow inside of her and filled her womb with his load. Her neck craned as her eyes rolled back from the feeling. After a second, he pulled out of her, causing his warm semen to floor out onto the floor.
"So much..." She moaned.
"How about we go somewhere more comfortable?"
After a moment, Ash lead Diantha out of the bath and into the halls, with only their underwear and nothing else, much to the Kalos Champion's embarrassment. She was worried of the idea that someone would see, but the man of the house seemed confident and wasn't worried in the slightest.
As they passed one of the windows, she could've sworn that she saw her Gardevoir out in the gardens with Ash's Lucario, doing what she and the world champ were doing earlier.
Once they reached the entrance to the master bedroom, Ash opened the door and allowed Diantha to go in first before going in afterward. If there was a small chance she was gonna be pregnant earlier, after that night, it was inevitable.
(Several months later)
After that night, Diantha Ketchum was welcomed into the family. Once word got out, people were shocked that he managed to get yet another older woman added, but also another league champion. It got them wondering who might be next.
Not only that, but it turned out to be true that her Gardevoir and the Pokemon Master's Lucario had gotten together as well. Imagine that.
Right now, our hero was with his new wife in his room, drinking milk from her now grown boob, rubbing her pregnant belly, while she was stroking his member.
"They've been getting real feisty lately. Really take after their daddy." Diantha says to him.
"I'll make sure to raise them properly. Plus, they're already gonna have a lot of siblings." Ash says.
They stopped and Ash put Diantha in his lap, inserting his member into her ass before he began thrusting. He was massaging her bust to keep her at ease, a bit of her milk trickling down the back of his hands while also taking it easy. This would go on until she sprayed her juices on the sheets before he came in her ass.
The Ketchum family is getting bigger and bigger. The Pokemon Master was looking forward to seeing more of his children come into the world and could only wonder what the future would hold for him next.
