[Mission: Make Pikachu your Slave
Reward: Unknown
Penalty: None]
[To make Pikachu your slave, you must have intercourse with her in both the vagina and anal, 2 times each.]
Seeing this message, Ash was stunned. He looked at Pikachu, who was looking up at him with strange eyes under the Heart Ball's influence.
A wave of sad emotions washed over him, there was no way he could do that to his best friend.
He shook his head in refusal. She's so small, he thought, feeling a mix of anger and disbelief at the system.
How could it ask him to violate such a tiny, innocent Pokémon? If it were a larger Pokémon like Meowscarada or Gardevoir, he might have considered it, but Pikachu?
His cock would likely hurt her severely just trying to enter.
Thinking this, Ash withdrew Pikachu into her Ball.
He made a firm decision: he would not make Pikachu his slave, at least not until he acquired some ability to transform her into a human form or make her larger.
He didn't want another sad situation like mom.
Ash's thought came back to the present as he entered Professor Oak's lab.
Inside, three people stood. Professor Oak greeted him with a warm smile. "Ash, you're just in time."
Next to the professor stood Mary, a girl with long orange hair and sharp black eyes.
She wore a black short-sleeved shirt, a purple skirt and a light gray pouch at her waist.
A purple wristband adorned her arm, and a green-yellow pendant hung around her neck. She completed her look with dark shoes and purple sock, giving her a confident and energetic appearance.
The third person was Daisy. She was a bit older and taller than Mary, with long light brown hair held back by a wide green headband.
She wore a sleeveless white top with red collar, a short green skirt, and long white stockings that reached above her knees, paired with simple white and blue shoes.
Her face was flushed, and she was trembling slightly.
"So… it's Ash," Mary said, her voice laced with a superior tone. She held up a Poké Ball.
"I already got the best Pokémon from Gramps."
Ash just looked at her, unimpressed.
In this world, Gary didn't exist, but Mary filled that role perfectly.
Mary was always popular with the other boys, a status built on her family's wealth and being Professor Oak's granddaughter.
And Ash had to admit, her genetics were… impressive. Despite being only ten years old, her chest had already developed to a noticeable B-cup and her ass was round and perky, hinting at a truly killer body.
And when she would fully mature, there was no telling how stunning and voluptuous she would become.
It was easy to see why the boys were so desperate for her attention.
Wherever she went, a group of young followers would always trail behind her, desperately hoping to win her favor.
Ash, however, had always been the sole exception to this. His heart had long belonged to the kind and beautiful Serena and he was confident that money and fame would come naturally once he became the Champion.
So he usually ignored her. Because of this, whenever Mary saw him, his refusal to chase after her like the others ignited a deep-seated frustration and a need to conquer his indifference.
This formed a fierce rivalry between them.
She was always trying to compete with him, but most of the time she lost, whether it was in Pokémon knowledge or having a first Pokémon.
He still remembered that summer camp when he found Pikachu. Mary, seeing the yellow mouse seating happily on his shoulder, immediately stormed over to her grandfather nearby.
"Gramps! I want a Pokémon too! Get me one right now!" she demanded.
Professor Oak adjusted his coat, looking down at his granddaughter with a patient but firm expression.
"Mary, it doesn't work that way. A Pokémon is a partner, not a toy you can just order and you will eventually get your Pokémon when you turn ten, just like every other trainer."
"But that's not fair!" she shot back, her voice rising as she pointed a finger at Ash.
"He has one! Ash has a Pokémon, look at his shoulder! Why does he get one and I don't?!"
"Ash didn't get his from me," the Professor explained calmly. "He found that Pikachu during camp time and slowly earned its trust."
"They had formed a deep friendship, and he hadn't caught it yet."
Mary's face flushed with anger and humiliation. "Fine! If you won't get me one, I'll get one myself!"
She then turned and ordered a group of her eager followers to go out with her and catch a strong Pokémon.
The boys, hoping to win her favor, charged into the woods with determination.
They returned less than an hour later, their clothes torn and covered in scratches.
Some had been stung by the furious swarm of Beedrill they had accidentally disturbed.
Not a single Pokémon was in any of their hands.
Ash, who had been watching the entire thing with Pikachu, couldn't hold back his laughter and laughed loudly.
The sight of them getting exactly what they deserved was just too perfect.
That laugh was the final straw. Mary, who had been dusting off her clothes after going into the woods with them, froze.
Her head snapped up, her eyes locking onto him with pure, undiluted hatred.
She marched over, stopping right in front of him and pointing a trembling finger at his face.
"Ash Ketchum!" she declared, her voice shaking with rage. "From today onwards, you and I are rivals!"
"Let's see who will be the stronger trainer when I turn ten! I'll prove I'm better than you!"
Ash simply looked at her for a moment, then let out a dismissive snort.
"Whatever," he said, turning and walking away without a care for whatever she said.
Seeing him still didn't care about what she said, tears formed in her eyes.
"Ash Ketchum, you… you jerk!" she screamed at his back, her voice echoing across the camp.
' ' '
"So, do you wanna battle?" Ash asked as he took out Pikachu's ball.
He wasn't worried about people noticing its unique design or the fact his Pikachu was now female.
Everyone except him and his mom had forgotten Pikachu was ever male.
This was clearly the effect of that Gender Swap Candy, maybe this was the reason why it cost 10,000 points.
As for the Heart Ball's appearance, it's not like trainers couldn't customize their Poké Balls.
"You think I am stupid, Ash? You have been training your Pikachu for years and I just got mine!" Mary casually pointed out the clear difference in their pokémon experience.
That's when Ash smirked at her, which made Mary even angrier.
"If only I had my Pokémon earlier…" she muttered under her breath, her fists clenching.
"Now now, both of you, calm down," Professor Oak said, stepping between them.
He held out two red devices. "Here are your Pokédexes. Ash, this is for you. Mary, this one is yours."
As soon as he and Mary took it, a mission appeared on the screens.
[Mission: Make Mary your Slave
Reward: Unknown
Penalty: None]
[To make Mary your slave, you must have intercourse with her 3 times in vagina and 1 time in anal.]
Seeing this mission, an evil grin appeared on his face as he looked at Mary. He had never expected the system would finally give him a mission to make her his slave.
But he did wonder, looking at Mary's trembling sister, Daisy Oak, why it hadn't allowed it earlier. For her sister, it had been given a mission from the start.
Note : I have replaced the character Leaf with Mary, as I have different plans for Leaf's role in the story.
