After Stealing Hero's Mother, I Reincarnated in the Fantasy World!

As he had said before, Celestia's body was like a treasure. No matter what body part was in question, Rain could say with certainty that it was more valuable than anything all the merchants of the world could ever offer.

Rain could enjoy her endlessly, no matter how many times he saw, touched, and penetrated her. And he was going to do the same today... but in an instant, a new thought came to him.

For today at least, he decided to change his approach a bit.

"Celestia, how about your ass?"

"My ass? My ass what?"

His aunt tilted her head to the side, not understanding anything.

Did Rain really want to touch her ass? Then he could have just asked for it...

"I mean, why don't we fully explore your ass this time."

Suddenly, a chill ran through her body, making her skin goosebumps. She hadn't fully realized what he was talking about, but she had a bad feeling...a very bad feeling.

"Anal sex."

...And it was immediately confirmed.

"A-anal?"

Celestia nearly choked on his words, coughing wildly. Swallowing hard, as if her throat was constricted, Celestia stared at him.

"Are you seriously...?"

She asked with visible apprehension, heeling backwards on the bed.

"I've never been more serious than I am right now."

Who jokes about such important topics anyway?

Rain started to move closer to her too, not letting her get any farther away. She slowly backed away as he slowly stepped toward her, like a predator ready to lunge at its prey at any sudden movement.

Thud.

In the end, the winner of this fight was soon decided. The victim was cornered, with no more space for her to escape to.

It was a foregone conclusion, from the moment she started to retreat, she was already doomed to defeat.

"Haha, Rain... you're such a good Nephew, aren't you...? You would never do such a thing to your beloved Aunt, right...?" The authentic version is on M|V|LEMPY_R.

She laughed nervously in the corner of the bed, pulling her legs to her and hugging them before hiding her face in them.

Unfortunately, that didn't stop his approach.

"Kyja!"

Celestia reacted with a cute cry as he flipped her over, putting her belly down. Even just lying on the bed, her ass was already defying the laws of nature by proudly towering over the bed.

"...It's a masterpiece that can't belong to humans."

Rain stared at her mesmerized, unable to look away while the darkest, darkest of his desires awoke within him.

Honestly, this happened every time he saw her butt. It took an inhuman effort for him to restrain himself from going on a rampage on her butthole.

"You're exaggerating, Rain..."

"Exaggerating? Did you say exaggerating, Celestia?"

He pointed at her ass, deeply shocked.

"Do you really think there's anything to 'exaggerate' here?"

It was already at its peak, and if it got even a fraction more, the structure of the world would fail and the very fabric of reality itself would tear, marking the end of the world.

"I mean, it's not as good as you say it is..."

Celestia tried to argue, not wanting to lose, but he only shook his head.

"Okay, if you don't understand the greatness of your ass and why I admire it so much, just watch. I'll prove it to you."

Still lying on her stomach, Celestia turned her head back and looked at her ass, intrigued by what Rain was about to prove to her.

Rain was about to start, but before doing so, a serious voice warned her.

"The main thing is to be careful, Celestia. If you let your guard down too much, that sight could make you lose yourself."

"..."

Celestia rolled her eyes at his pretentious words. But Rain wasn't kidding, so only after waiting for her reluctant nod did he proceed.

Raising his hand in slow motion... he brought it down on her plump ass in one swift, downward stroke.

SLAP!

A deafeningly resounding slap echoed through the room, making one question whether such a pure and sublime sound could have come from a collision with flesh.

Celestia blinked in surprise and really hadn't expected it. She was already ready to admit that Rain was partially right, but he only silently pointed at her ass as if to say, this is just the beginning.

It was at that moment, when the ringing sound of the blow finally dissipated into the silence of the room, that waves began to spread from where his palm had landed to the flesh of her firm ass.

It wasn't something you could see hitting an ordinary ass. These waves were like waves of water, soft but firm, supple but gentle, in a word, they were... perfect.

If her ass had been a little less soft or a little more firm, this effect could not have been achieved. It was something that was only possible with a perfectly balanced ass.

Unable to look away, Rain stared at it, left speechless.

Even when the first wave from his blow went through her plump ass, it wasn't the end. Because of her extreme firmness, they returned to his palm again, sending pleasurable vibrations throughout his body, and from there they dispersed again across her masterpiece ass...

It's unknown how much time passed, but it stopped eventually, plunging the room into complete silence.

Celestia blinked a few times, coming to her senses. She had to admit that what Rain had shown her was indeed quite unusual. But was it really worth making such a big deal out of it?

Celestia shook her head.

"Rain, I understand the meaning of what you said and it did seem unusual, but am I really still... Rain? Rain, can you hear me? Rain...?"

No matter how many times she called out to him, he didn't respond, frozen in place. It wasn't until Celestia became concerned and shook him by the shoulder that he came to his senses.

"Sorry, I think I'm going into a trance."

"..."

Rain looked around with curiosity, as if he had returned to this place after a long journey.

"Oh and it seems I have gained some Enlightenment regarding the path of the sword...."

"..."

Celestia stared at him blankly, unable to find the words.

What was a trance?

A mysterious phenomenon where one's spirit leaves the body, completely merging with the world around them, achieving a perfect balance with it. A state where you transcend your mortal limits, your mortal body, for a brief moment rising above everything else, becoming like a weightless, pure, untouched by the filth of the world, a cloud floating high in the sky.

It was rumored that at this level of unity with the world around you, all its secrets cease to be a mystery and are revealed to you, bringing, to the one who has reached it, such a legendary thing as Enlightenment.

Enlightenment was a special moment when pieces of the truth of the world appeared before you, instantly helping you make phenomenal progress in your field, whether it was creating new techniques or inventing your own styles.

All cultivators dreamed of achieving this. And they weren't the only ones. Alchemists, Martial Arts Masters, Priests, and even ordinary people all aspired to attain it, even if only for a moment.

But although many people tried to achieve it, only a few succeeded. It was something beyond ordinary experience or talent, more like a divine miracle than something human.

And now, in that mysterious trance state, when his entire spirit left his body, perfectly in sync with the waves on her ass, a sudden epiphany hit Rain like thunder.

He had reached Enlightenment.

Problems that he could not solve before found their solution, and bottlenecks that hampered him found their way out. His foundation of martial arts became stronger, and his swordsmanship became deeper.

It seemed like his entire world had turned upside down, causing him to close his eyes and completely assimilate the remnants of this Enlightenment.

"..."

Celestia silently stared at him with her mouth open. She also knew all of this, but that was why her mouth couldn't close.

Cultivators went into seclusion, renouncing all human companionship and worldly pleasures, meditating for decades under a raging waterfall, sleeping on bare cold rocks, and eating only bitter herbs, all in order to approach the state of Enlightenment. But to get it from... ass?

Not only Rain, but Celestia felt her world and standard foundations begin to turn upside down before her eyes.

Normally she would have just dismissed it as nonsense, but due to her high level, she could see the tiniest changes in his aura, which was impossible to achieve without gaining a sudden leap in comprehension. She was forced to believe it.

"Getting Enlightenment from my ass... is it really that good?"

Turning around, she took another look at her ass.

"..."

They were the same plump buttocks she had lived with all her life, sharing joy and sorrow, anger and sadness, but it seemed just now they were covered in a special layer of mystery and obscurity, radiating a special aura of greatness.

"...Perhaps I really should learn something from them..."

Recalling Rain's words earlier, they once again took on a deeper meaning. At the same time, Celestia suddenly noticed something and with a cough, looked away.

"Rain... when you were talking about the sword... you weren't talking about that 'sword' were you...?"

Celestia pointed her exquisite finger confusedly at his cock between his legs, which once again stood proudly looking upward like the truest of swords, its tip pointing directly at her ass, as if marking its next target.

When even the owner of this treasure finally recognized its value, Rain smiled in relief.

'My mission is accomplished here.'

'...And another should be about to begin.'

Resuming the offensive, his hands gripped her hips and turned her around in a comfortable position for him. Realizing what was wrong, Celestia immediately flailed her arms wildly, trying to escape.

"Stop, stop...! If you really admire and idolize my butt so much, wouldn't what you want to do be considered blasphemy?!"

Quickly finding the perfect way to defend herself, Celestia grasped onto it tightly. It was her last desperate chance to save her little hole from this pervert.

Unfortunately...

"Celestia, the truth is that some things only get better after defilement. You should have realized that from experience by now."

Looking off into the distance, he said melancholically.

"Sometimes that's what it takes to help one reach the true ideal."

His words were full of unyielding faith, as if he were a zealous fanatic willing to do anything for his cause.

"And if I have to take on such a sin to elevate your ass even more...I will gladly sacrifice myself."

...And contrary to his melancholy voice, his cock was bouncing furiously, as if it couldn't wait for its meal.
