──At Princess Victoria's command, the brother and sister set out hand in hand on a journey to defeat the Demon King.
The long battle of the hero Leon... was finally coming to an end.
"Brother, now!"
"I know - this is the end!"
A dimly lit stone hall with an eerie cold air.
Mel and Rion's powerful voices echoed throughout the throne room on the top floor of the Demon King's castle.
Mel raised her axe staff of light and activated a physical strengthening spell, and at that moment Rion received it and ran powerfully towards the enemy in front of him.
"Stop being arrogant, you human being!"
A man with black skin covered in wounds and blue blood flowing from his veins - the Demon King, leader of the monsters with an impressive single huge horn, raised his right hand, holding a huge sword that emitted an ominous aura, in an attempt to intercept the attack.
The demon sword Chaos Bringer is the symbol of the Demon King's power. Rion narrowly avoids a blow from the cursed sword, which is said to take all life with just a scratch.
"Uriyaaaah!"
Thud!
The holy sword was swung down with the speed of a flash, and with a dull sound, the Demon King's raised right hand was cut off at the shoulder.
"Ugh, aaaahhh...!?"
The Demon King cried out in pain and fell to his knees while holding his right shoulder, from which blood was gushing.
The enormous magical power that had been intimidating the siblings until just now was beginning to weaken, and the battle was over.
"I won..."
This morning, we invaded the Demon King's castle and defeated many enemies before arriving at this place.
The hour-long fierce battle with the Demon King, the final enemy that had been waiting for them, was finally coming to an end.
"You... so many people have been sacrificed because of you...!"
Villages were brutally destroyed. People were grieving the loss of their families and loved ones.
The sad scenes I had seen during my journey came back to my mind.
If they could defeat the Demon King, who is the source of all evil, they would surely be able to find some relief.
"At Mel's signal, my brother defeated the Demon King... it was a perfect collaboration between two people who care about each other. After all, Mel and my brother are destined to always walk side by side. There's no doubt about it, absolutely... fufufu, fufufu, fufufu..."
The younger sage sister, who had supported him with numerous spells during the long battle, also bowed her head with a deep emotion and muttered something under her breath.
I couldn't hear it clearly, but they only shared their joy after the final blow.
"Prepare yourself, Demon King! This is the end..."
Leon was not unscathed either, and he didn't have much strength left.
I will use this opportunity to decide. With a firm resolve in my heart, I raise my holy sword - and at that moment.
"Wait, hero! I surrender, so please spare my life!"
The Demon King, who had maintained an insolent attitude up until now, suddenly shouted in a pathetic, high-pitched voice.
Rion's eyes widened at the sudden change in his appearance, but he couldn't contain the rage that was welling up from the bottom of his stomach and his face immediately stiffened.
"Don't mess with me! Do you know how many people I've sacrificed up until now?!"
He had seen countless people become victims, and one of the reasons his parents were killed was because the demons had become more vicious than they should have been.
No matter how kind-hearted the hero is, he cannot accept it right away.
(But, cutting down someone who is begging for their life is...)
Unable to let go of that thought, he hesitated for a moment.
Taking advantage of this opportunity, a figure slipped past the hero brother who was standing still.
"Help me? What nonsense are you talking about, you idiot?"
Holding her staff of light, Mel looks down at the crouching Demon King with a cold gaze.
Overwhelmed by the force of the attack, Rion instinctively took a step back.
"Um, um, Mel..."
"It's okay, big brother ♪ Leave the trash cleaning to Mel."
Saying this, the younger sage lightly raised her axe staff.
The light emitted from it enveloped Leon, and the wounds he had sustained in battle disappeared in an instant.
(That's a really amazing healing magic... but this is no time to be impressed!)
The hero suddenly comes to his senses, but can't think of what to say and just watches the situation unfold.
"Wh-What is it, you bastard? That power... aren't you just a wizard?"
The Demon King was also absorbed in Mel's strange aura, his shoulders shaking slightly.
"You, you... you hurt my brother! If you had never appeared in the first place, my brother wouldn't have had to go on this journey. He wouldn't have had to suffer so much!! It's all your fault, everything... haha, hahaha, I won't forgive you, I won't forgive you, there's no way I can forgive you! There's no need to forgive you, right? haha, hahahahahahahaha!"
The younger sage's voice, looking down at the Demon King, gradually gets higher and higher-pitched, and finally turns into a laugh filled with madness.
"Wait! Make a deal with me..."
The Demon King, who had been completely consumed, pleaded in a panic.
However, Mel glared at him with eyes that had lost their light.
"...Just die."
The death sentence was pronounced in a monotonous, gloomy voice.
Before the Demon King could react, Mel raised her axe staff with both hands and brought it down with such speed that even Rion's eyes couldn't follow it.
Bang!
The Demon King's head was about to utter a cry when it was shattered into pieces by a single blow from the heavy axe.
The red flesh flies off into pieces, just like a watermelon splitting open.
"Die, die, die, die, die, die, die, die, die, die, die, die, die! For the sin of hurting Onii-sama, for the sin of making him sad, for the sin of making him suffer! It's still... still not enough. Don't think that this is enough to make up for it. Ahaha, ahaha, ahahahahahahahaha♪"
While Rion was frozen by the horrific scene, the younger sister sage laughed insanely and continued to swing her axe staff with the force of a tornado.
"It's still not enough. It's not enough. You hurt and tormented my brother...Mel's precious brother...and you did it right in front of Mel! I can't forgive you, you scum worse than trash, I don't want to forgive you. Ahaha, ahaha, not yet...not yet!!"
Squish, squelch, slurp!
Mel screamed as if possessed, and every time she swung her light axe down, an eerie sound was heard and red pieces of flesh flew everywhere. Fresh blood spurted out, staining Mel's flushed cheeks, but that didn't stop her hands from her gruesome "dismemberment work."
"Just die! Die, die, die. If you die, you won't have to continue being the hero anymore. You'll always be Mel's brother. I won't hand you over to that sow. You'll always be my brother. Always and forever... hehe, ahaha♪"
The remaining body of the Demon King is dismembered and turned into mushy minced meat.
Along with the chilling, insane laughter, the pure blade of light that formed the axe changed color as if it had absorbed the blue blood of the Demon King.
Along with the large pool of blood on the floor, a strong smell of iron filled the air.
The unbearable stench made the hero vomit, but he finally regained his composure.
"Ugh... Hey, Mel! Wait, that's enough! That's enough!"
The Demon King is an opponent that must be defeated, but tormenting someone who is already dead to this extent is something that cannot be forgiven, no matter how sinful the person may be.
Just like the blue-black stain of the light axe, it felt as if Mel's heart was being stained as well, so Rion called out to her, wanting to stop her as quickly as possible.
It's a wonderful darkness.
"Huh..."
A low voice came from somewhere.
"Who are you?! Damn it, Mel, don't let your guard down."
"Who is it that is interfering with the disposal of the trash that harmed my brother?"
Responding to Leon's voice urging caution as he readied his sword, Mel, who had been continuing his murderous rampage, finally stopped his hand and began to survey his surroundings with dark eyes.
However, no matter how hard they strained their eyes to search for any sign of the voice, they could not find the owner of the voice.
Immediately afterwards, Rion's face clouded over with an indescribable sense of anxiety.
--I'm sure he will become a greater Demon Lord than the vessel you destroyed.
The same voice came again from the Demon King's corpse, which had turned into a mass of flesh and was spread out on the floor.
"Ugh, Mel, get away! ...Guah!?"
Rion screamed and ran to grab his sister and protect her, but was suddenly blown away by a gust of wind like a storm, and slammed backside into the wall.
"What... is there something inside Mel... Ahhhh!?"
Black smoke rose from the mass of flesh, engulfing the blond-haired sage's body.
Along with the high-pitched scream, it fades away as if seeping into the translucent white skin.
"Ugh, what's going on here?"
Rion stood up, using the holy sword as a walking stick, biting his lip in confusion.
The Demon King was brutally destroyed by Mel's hands.
If that's the case, then who is this voice? I have no idea.
"...What you destroyed was nothing more than a vessel. It was nothing more than one of the bodies I have used and discarded since time immemorial."
As Mel was consumed by the black mist, a low voice that wasn't her own came out of her mouth.
"What do you mean!"
"The Demon King is me. I have escaped the shackles of my body that bind me to mortal life, and am the absolute strongest being who rules over eternity. This girl is my 100,000th vessel..."
"...No way."
Rion finally realized that the owner of this voice - the black mist - was the true Demon King.
Since ancient times, there have been many legends of demon kings being defeated by heroes.
However, no matter how many times the Demon King is destroyed, he will always rise again after some time has passed.
This is because all the heroes up until now, including themselves, have merely destroyed the bodies that the Demon King had used as vessels. The true Demon King, or should we call it his soul, has continued to survive for eons.
"Get away from Mel! Ugh..."
If things continue like this, my beloved little sister will be taken over and resurrected as the new Demon King.
He must avoid that somehow, so he readies his holy sword and charges forward.
"Oh, so you are going to harm this beloved girl's body."
"That's... Ugh..."
Hearing the triumphant voice of the Demon King, Rion stopped in his tracks with a sour expression on his face.
There was no way that her brother, the hero, who cared about her more than anything, could have cut down Mel's body along with the Demon King's soul.
(Mel might have been able to drive away the Demon King's soul without harming his body using evil-destroying magic or something. But I can't use that kind of high-level magic...!)
If only he had been taken over, there might still have been a chance.
Despair stains everything in front of me dark.
Still, he cannot give up on his sister, and with his holy sword tightly gripped, he desperately devises a plan.
"Will you be swayed by your emotions and lose everything? How foolish, hero. How foolish, human. You will not grow even after the passage of time. Do not worry... When I take control of this body, I will be the first to chop off your head. Travel to the underworld with your beloved sister by your side."
Mel turned to Leon and a triumphant voice like that of the Demon King came out of her mouth.
The younger sage's eyes, which had been a clear blue like the clear blue sky, had turned a deep red, indicating that they had been taken over by an evil spirit.
"M, Mel... Don't lose, Mel! To the Demon King's soul..."
Is it all hopeless? The hero, feeling despair, pleads desperately with a glimmer of hope.
"It's useless. What can a girl do against an immortal like me..."
The Demon King's soul was about to say something to deny Rion his hopes - but then its voice was cut off unnaturally.
"You... you idiot... you think you can resist me? That's... impossible."
The next thing I heard was a desperate voice, with all the calmness from before gone.
"The impossible part is mine. I can't believe it. I've never experienced anything so horrible. Trying to hurt my brother with Mel's own hands... I will never, ever forgive you. Are you ready? You are the lowest of filth, it's a shame to even call you trash. Hehehe."
『Why?! Is it possible that a soul exists that can spurn my control... Uh, ohhhh?!』
"Go away, go away you stubborn old man. There is no need in this world for anyone who tries to make Onii-sama sad or hurt him. Hehe, come on, go away... just disappear!"
Mel's voice was tinged with madness, just like when she was dismantling the Demon King's body earlier. Then came the voice of the Demon King's soul, screaming in a panic.
Two voices came out of Mel's mouth, alternating between them - sometimes simultaneously.
"What's going on? Mel... do your best! Please..."
Sensing that Mel's soul was desperately resisting, Rion could only cheer her on, unable to think of anything else to do.
As if in response, Mel's face, which had been expressionless until then, suddenly breaks into an ecstatic smile.
"Don't worry, Onii-sama ♪ Soon... I'll clean this up just like that trash from before. Fufu, trying to drive a wedge between Onii-sama and Mel is foolish... truly foolish, an unforgivable existence worse than trash. Get out... Get out, ahaha, ahahahaha!"
"I-I-It's being swallowed... I-It's impossible! My soul, which has survived for eons... is being devoured, what is this th-this darkness... the darkness of the abyss that even erases me, the Demon King, oh ...
Along with Mel's loud laughter, the painful cry of the Demon King's soul could be heard.
At the same time, the black mist surrounding the younger sage vanished as if it was being sucked into her body - and the next moment, a gust of wind blew again, this time from around her.
"Ugh!? Ugh... Melt, Melt!"
This time, somehow managing to hold his ground and endure it, Rion desperately continued to call out the name of his sister... his beloved girl.
The wind stopped, and there was no reply to the voice.
"...Huff."
The younger sage with the staff of light sighed softly as if nothing had happened.
He slowly took out a handkerchief from his pocket and began wiping the Demon King's blood that had splattered on his cheek.
"M-Mel, that's..."
Is she now his precious little sister? Or is she the Demon Lord?
Unable to get any confirmation, the older hero timidly calls out to him and checks the situation.
"Brother, I'm sorry for worrying you."
"I'm glad...Mel, you're safe."
The happy eyes that looked straight at me had returned to their original clear blue color.
The gentle smile on her lips, the lively tone of her voice when she calls him "Big Brother."
Having lived with her for so long, Leon knew for sure that this was the sister he knew.
If it had been taken over by someone else, there's no way that even the smallest details would remain intact.
"I'm sorry, it was my fault for letting my guard down...!"
Impatient to return the holy sword to its sheath, he threw it down and immediately hugged Mel to his chest.
The warmth that is radiating from her. The sweet scent that wafts from her soft hair. It reminds me once again that my beloved sister has returned safely to my arms, and I can't help but feel tears welling up in my eyes.
"Oh, Onii-sama, you're so passionate. Mel... I'm so happy."
"Mel, does anything hurt? Where is your Demon King soul?"
"Don't worry. I did the same to him as I did to this one."
Mel looked up at her brother the hero who had asked the question and answered with a big smile, then with a violence that didn't suit her, she trampled on part of the Demon King's corpse that was lying at her feet.
"Trying to hurt my brother with Mel's body is something I can't forgive, just thinking about it makes me faint. Seriously... So I ended up getting rid of him in Mel's heart. No matter how much she screams and cries, I won't forgive her! Blown into pieces... How dare she try to control Mel's feelings for my brother with that level of power? She was a fool worse than even filth."
"I, I see..."
The wise younger sister spoke with a merciless tone, still smiling.
The indescribable force of the words left Rion nodding in response, not having the energy to ask any further questions.
Today I was shown once again how ruthless he is when he gets involved.
(I'm glad you think of me, but I think you're going too far...)
Thanks to that, he was able to defeat his true enemy, the Demon King's soul, so he should be praised for now, but he will need to be a little more toned down in the peaceful days that are to come.
(Well, we can talk about that later.)
I try to sense my surroundings again, but this time I really don't feel anything.
The journey to defeat the Demon King has just come to an end.
"Okay, let's hurry back, Mel. There's no need to stay here long."
As usual, he called out to his sister, who was rubbing her nose against his chest and acting cute.
Many people in the royal capital are waiting for good news, and I want to deliver it to them as soon as possible.
Thinking this, he tried to let go of Mel's body - but...
"I'm not going back."
The younger sage wrapped her arms around Rion's waist and hugged him tightly, tilting her head cutely as she declared.
The light had disappeared from his blue eyes, giving off an eerie intensity.
"Huh? What do you mean, you're not going home? I have to quickly let everyone know that I've defeated the Demon King and put their minds at ease..."
"Everyone...no, isn't it the princess?"
"Huh?"
"Brother, who defeated the Demon King, is truly worthy to be the next king. And so the princess... and the scum who flirted with brother, are waiting to pair him with that thin-skinned, pretty-looking sow at heart. Is that the place you want to return to...?"
Creak... The arms around my waist tighten, and the soft sound of bones creaking echoes.
It seems impossible to shake it off. Even his brother, Leon, had no idea it had such power.
"M-Mel, what are you talking about? And how rude of you to talk to the princess like that..."
It was a completely different look from the one directed at the Demon King earlier, but it was just as intimidating.
Leon was unable to shake off his sister's arm and could only scold her.
"Brother, are you protecting that sow? She's more important than Mel."
"That's not what I said! Mel, what's wrong? Something's wrong."
"It's not strange! Onii-sama wants to go home early... and when I think that it's because he's been deceived by that sow who is willing to offer her body just for the sake of his own interests, Mel can't just stand by and watch!! So... hehe♪"
Immediately after the younger sage smiled dreamily, multiple cracks appeared in the stone floor beneath her feet.
"What!?"
When Rion noticed the presence of evil and cried out in surprise, several tentacles stretched out and entangled his arms and legs, scattering stone fragments everywhere.
Before he could resist, he was pulled down and found sprawled on the floor.
"Ugh, there's still the enemy... Mel, run!"
Even though they had defeated the Demon King, they had let their guard down far too much in enemy territory.
While feeling deep regret, he desperately shouted to protect his sister.
"It's okay, Onii-sama. After all, these children are my familiars ♪"
Looking down at her fallen brother, Mel spoke with her usual gentle smile.
"...Huh?"
Rion didn't understand what he meant and blurted out a voice that didn't fit the tense atmosphere.
He quickly checked, but all the tentacles that had grown out of the cracks in the floor had wrapped around his limbs. Not strong enough to break any bones, but just enough to restrict his movement.
Tentacle monsters prefer women over men, and attack their prey with naked instinct. This scene, which was unthinkable given their nature, finally made me understand what the younger sister sage had said.
"M-Mel, when did you learn to summon monsters like this..."
There was no way that Mel, who was a user of healing magic, a symbol of holy power, could remember summoning a familiar, which could be considered an evil technique.
While her brother was dumbfounded and unable to understand what was going on, Mel answered with a hint of pride while ruffling her beautiful blonde hair.
"Just now. I destroyed that demon king who was inferior to garbage and tried to get Mel to hurt my brother. However, his powers seemed very useful, so I took them all♪"
As she smiled, Mel's blue eyes turned a fiery crimson.
It was the same change that had occurred earlier when he was almost taken over by the Demon King's soul.
"Mel has always thought that... I don't just want to be protected by Onii-sama, I want the power to protect him. From monsters, from the scum who take advantage of Onii-sama... and also from the sow princess who stared at him with those lewd eyes."
Mel muttered something to her confused brother, then sat on top of his waist.
"So, Onii-sama... please give Mel a reward ♪ For your sake, I killed the Demon King... and took away all of his power so that he would never be able to revive again. I want Mel to give her first time to Onii-sama. I want to take your first time... ahaha."
The blonde-haired sage licked his lips, wet with his own saliva and his brother's sweat, and slowly opened the front of his robe to reveal it.
The voluptuous twin hills spilled out from her chest. They swayed slightly with her movements, and were so large that Rion could not possibly grasp them in his hands, and were shaped like beautiful bowls.
Her skin is white as if it has been infused with milk, the areola in the center is so modest that it could be hidden by her brother the hero's thumb, and the pointy flesh is a cute size.
Although Leon knows he shouldn't look, he can't take his eyes off it.
"What do you think, Onii-sama? We used to always take baths together when we were little, but you've grown a lot since then, haven't you? Have your breasts become the way you like them?"
"Th, that, um, that's..."
"It's fine, I'll ask the answer directly here."
Mel whispered in a sweet voice as she gently reached her beautiful, white fish-like fingers between Rion's legs.
In just a moment, the clasp around his crotch was undone and his erection, which had been tucked inside his trousers, was taken out.
"It's been a while since I've seen Onii-sama's penis. When it was little it was covered with foreskin and had a really cute shape... but now the tip is bare, reddish-black... and strong♪"
"Hmmm, haa haa, ah, uhh, Mel... ahhh"
Her slender fingers wrapped around my shaft were tapping the underside of my shaft and just below the gooseneck as if she were playing the piano. Just that movement, as if to check the sensation, sent a sweet tingle through the core of my erection, and I couldn't stop my momentum from increasing.
"Big Brother's penis is getting bigger and bigger. I'm so happy... I guess Big Brother loves Mel after all. He doesn't just want me as his little sister, he wants me as a woman too... Not as that sly pig princess, but as Mel... Afu, I'm so happy."
With a high-pitched voice, the younger sister wise woman cupped the tip of his erect penis in her palm and lovingly stroked his stiff glans.
"There, agh, ugh!"
The stimulation of his erect penis being relentlessly rubbed against his most sensitive part made Rion involuntarily lift his hips.
A sweet numbness reverberates all the way to the base of my rod, making it impossible to contain the hot breath rising inside me.
Something hot rose up into my urethra, and an obscene, squelching sound began to form.
"Fufu, it feels good ♪ Mel's hands feel so good, sticky juices are coming out from the tip of your penis."
"S-Stop it, Mel. This... we're brother and sister!"
The penis being played with by his sister is already so erect that thick veins are visible on the surface of the skin.
If this continued any longer, he might make a real mistake. The hero brother gathered his remaining rationality, calmed himself down, and appealed to his out-of-control sister.
"I know. That's why Mel has been holding back until now. I really, really love Onii-sama. I always want to be able to touch you. I want to be able to look at you. I want to breathe the same air as you. I want to share the same emotions. When we eat, when we bathe, when we sleep...it's embarrassing, but even when we go to the bathroom. Mel wanted to be alone with Onii-sama. I wanted our relationship to be deeper than just brother and sister...I've always, always thought that...but if I was selfish, it would cause trouble for Onii-sama, so that's why I held back."
Looking down at her brother with her lightless crimson eyes, Mel let out the rage she had been hiding deep inside her heart.
Overwhelmed by the stronger feelings than he had expected, Rion is unable to say anything and can only listen to his sister's frantic confession.
"Mel doesn't care about anyone other than Onii-sama. No, I don't want you to like me and pay attention to me... I don't want you to taint Mel, who is all yours, with your gaze, so I would rather you dislike me if possible. But Onii-sama is a kind person... It would surely hurt her if people around her started to avoid her. Mel cares for Onii-sama more than anyone else, and I would do anything for him. But even so, I couldn't protect him from everything in the world by myself. That's why I've been holding back until this day... But it's okay now. Mel, I've obtained it♪ The most incredible power in the world♪ The power to protect Onii-sama... The power to devote myself to him."
Mel stopped talking there, put one hand on her crimson-colored cheek, and smiled happily.
At the same time, the tentacles that had been entangling the hero brother began to move vigorously.
The "power" that Mel spoke of was...
"The power of the Demon King, th-that's why..."
"Yes! The current Mel can protect Onii-sama even against the whole world. Even if that sow princess leads an army to kidnap Onii-sama, she'll fight back... ufufu, fufu, ahahaha♪"
The younger wise woman nodded vigorously at her brother's words and burst out laughing as if she couldn't contain herself.
A soul that has ruled over many powerful demon lords for many years.
With the strength of his feelings alone, he destroyed it and took away its power.
It's hard to believe, but the tentacles wrapping around his limbs and the powerful magical power emanating from his blonde-haired sister are real.
"Mel..."
Because I love the other person, I can't confess my love.
Rion finally realized that she was also suffering from the same conflict as him.
She knows she should stop them, but she is so happy to know that they have feelings for each other that go beyond brother and sister, and she can't stop her heart from beating fast.
(But, stealing the power of the Demon King... I don't know what kind of negative effects this will have...)
Anyway, we have to stop Mel, who continues to run wild as if she's in a fever.
First, I have to do something about the tentacles that are entangled around my limbs.
With the strength of a brave boy, he should be able to tear this much apart even without a sword.
"Hehe, Onii-sama...these children are Mel's familiars. In other words, they share Mel's senses. It would be much appreciated if you refrain from acting too violently."
"Ugh, I, I see..."
I remembered that familiars summoned by magic share all of their master's senses.
If she hurt these tentacles, the pain would be transmitted to Mel. Tearing them apart would be a violent act, something her brother, who cares for her more than anyone else, could never do.
With no other option left, Leon gasped as the throbbing in his groin grew stronger and stronger, and simply looked up at Mel in a daze.
"Big brother has made his penis so big... look, Mel has grown like this too."
As if she had been waiting for this, the younger wise woman continued to stroke the tip of his erect penis with one hand, and with the other hand she gently picked up the hem of his skirt, which was decorated with white frills.
Before he could look away, the hidden place came into view of the hero brother.
She was wearing pale pink shorts similar to the holy garment she was wearing, but there was a large stain on the crotch that stretched from her pubic mound down to her buttocks.
From the center, which was the wettest part, probably the part that touched her private parts, a transparent drop was dripping...drop by drop.
"Haa, it's so embarrassing. Onii-sama is using Mel to make his penis bigger... Just thinking about him wanting Mel as a woman makes my naughty juices flow nonstop. Ahh, it's just overflowing, haa, ahh."
As she shows off her embarrassing parts, Mel, intoxicated with shame, becomes increasingly breathless.
The nectar began to drip from the fabric at an increased rate, and a thick, sweet smell like boiled flower nectar drifted all the way to Rion, making him choke.
(Mel's scent... a woman's scent I've never smelled before...)
As I was surrounded by my sister's feminine scent, my consciousness began to fade as if I had taken a sip of strong alcohol.
As she caresses and caresses his erect penis like a baby, it spasms intermittently and swells beyond its limits, almost to the point of tearing its skin.
He had been devoted to his sister and had no interest in women at all, but ever since he woke up as a "man," he had never been this excited.
It felt as if my scrotum was being tightly gripped, and it felt as if the thick, simmering liquid inside it was about to erupt at any moment.
(No, that's not good. It'll ruin Mel...)
He soils his beloved sister's beautiful hands with his own desires. Just imagining it fills his heart with indescribable joy, but it is not something that can be allowed.
"Let go, Mel. This is no good! Siblings like this... Ugh, we need to seal away the Demon King's powers quickly! We don't know what kind of effects it will have..."
"Why do you say that? Even Onii-sama wants Mel so much. Lol, look... my palms are already so dirty with the slimy liquid coming out of his penis. I'm sure I'll never be able to get rid of Onii-sama's naughty scent♪"
Shaking off her brother's attempts to stop her, Mel raised the palm of her hand that was wrapped around the head of his penis to show it off.
Just as she said, the spot, which was completely intact, was now wet and sticky with a stringy, transparent liquid.
"Big brother's juices, mhh, lick, ahah, they're different from sweat, they're saltier and fishier, and they make me feel really horny, mhh, haa, I've smelled them from time to time when I was doing the laundry, but the fresh smell is even more wonderful. Mel's crotch, pussy, and uterus are tingling, mhh, lick, kiss, smack♪"
Without hesitation, Mel brought her dirty palm to her mouth, narrowing her eyes in ecstasy as she savored the scent. Unable to resist, she stuck out her tongue and licked it up as if to show off to her stunned brother.
"Laundry...Mel, even doing that..."
My beloved sister happily tastes the pre-cum leaking from her own erection.
Confronted with the reality that she was secretly burning with even more passion than he did, Rion was at a loss as to what to say.
I'd defeated the Demon King and completed my mission as a hero. Just when I felt relieved, so many things had happened that it felt like my head was going to explode.
All I could do was watch, shivering slightly, as Mel relentlessly ran her tongue over my palm until it was completely covered in her own saliva.
"Hafu, the taste of Onii-sama has made Mel unable to resist any longer. Isn't it great, Onii-sama's penis is squirting out so much naughty juice and inviting Mel. Like this, in this embarrassing place for Mel... nfu, let me eat this penis with the pussy that has grown to be dedicated to Onii-sama. Like this, knnnn♪"
The blonde-haired sister's voice gradually rose in pitch and she thrust her hips forward.
Her crotch is soaked from absorbing too much nectar, and the shape of her slit is clearly visible, with a straight vertical line running through it. Without any hesitation, she rubs her stiff, erect penis against it.
"Mel, w-wait! No way, ahh, it's hot, ahhh!!"
Squelchy, squishy...squishy.
With each rub, the crotch cloth oozed a generous amount of sexual fluid, rubbing against the taut skin of his shaft and making an obscene splashing sound. Through the smooth, silky fabric, he could clearly feel the burning, melting mucous membrane.
When the underside of his penis is rubbed as if honey juice is being spread over it, the heat coming from there envelops his lower abdomen in an unknown pleasure, as if his shaft is melting.
"Big brother's penis is trembling very vigorously. If it's this naughty, then penis isn't such a cute word anymore. Cock♪ It's a cock that wants to violate my little sister Mel a lot. Mmm, I love it, Big brother's cock, Mel, I love how rough it feels! Ahh, this is the cock I've always imagined Big Brother's cock to be, the cock that will make Mel into a wife, a mother!! More... ahh, hmm, this is getting in the way. It has to be direct... hah, hafu."
The younger sister wise man shouted in excitement as if she had been lit on fire, and impatiently pushed the crotch of her shorts to the side.
The slit, now freed from the clinging fabric, had an elegant shape with no excess labia visible, just a thin line running down the center of the soft, plump labia majora.
Her lips were probably completely swollen with the nectar that was flowing endlessly. When her lips touched her brother's erect penis, they easily opened their mouths, exposing the pale pink aphrodisiac mucous membrane, which clung to his shaft like a suction cup.
"Hahi, ah, I can feel the heat of Onii-sama's dick directly in my pussy, mhm, haa, ahhh, Mel, I'm making lewd noises. I'm getting more juices coming out, hafuu♪"
That sensation must have really caused Mel to lose control, as she began to shake her hips back and forth as if dancing, her fluffy blonde hair wildly messed up.
The labia minora, coated with a generous amount of honey right up to the gaps between the shallow folds of flesh, tickle the underside of the penis, and the small bulging lump of flesh at the edge thrusts against the glans as if begging for attention.
"Uhh, ugh, ahh, Mel, no, no! This can't be, aaahhh."
Even through her shorts it felt so good I could lose consciousness, but having my cock rubbed directly against my beloved sister's private parts gave me an even greater level of pleasure.
The lewd sounds of her being sucked rang out, and his alter ego was devoured in a forbidden place of his sister that even he, her brother, had never seen before.
You are made painfully aware of the reality of such immorality.
Her cries of trying to stop were overshadowed by the endless waves of pleasure, and contrary to what she was saying, it seemed as if she was begging for stronger stimulation.
My sister, who was straddling my waist and attacking me, must have decided the same thing, as she licked her flushed, reddened lips seductively and began to move her hips in a spurt.
"I love you, Onii-sama. I really like you! You are everything to Mel, and what Mel wants is for you to always be smiling, for you to be happier than anyone else... I won't let those scum and sows who only try to use you lay a finger on you! Mel, who loves you more than anyone, will make you happy, so stay by Mel's side, always by Mel's side! Please love Mel's pussy lots. Hahi, I love you, I love you, I love you, I love you, Onii-sama!"
"M-Mel, no, this, oh, wait, aah, aaah!"
The underside of his erect penis is firmly gripped into the gaping slit, and he is jerked up and down at a dizzying speed.
Occasionally, I felt a sensation as if my underside was being sucked, which was caused by the gaping hole in the center of my vaginal slit - the opening of my vagina - repeatedly opening and closing in small movements.
I want to be let in here soon. I want my younger sister to be a woman.
It felt as if his cock was making a silent plea, and even though I knew it was wrong, the pleasure of being desired by my beloved made my spine tremble violently.
The inside of my head gradually became white.
"I love you, Onii-sama! I'll make Mel my wife, aha, ahhh ♪ It's hitting my clitoris, the tip of my dick, hihh, I'm cumming... mmmm!"
The moment Mel arched her back and thrust her hips forward, the female nucleus adorning the edge of her slit dug into the opening of her vagina, which had become swollen and spread open due to the pre-cum.
The hard sensation pushes open my hole, sending a current of pleasure down to the base of my rod.
As if in response to this, something hot welled up from his base, and no matter how hard Rion tried to resist, he couldn't stop it.
"I'm, ahh, uuuuh! Mel, ugh, aaaahhh!!"
Spurt, spurt, spurt, spurt, spurtttt!
Rion simply shouted his sister's name, becoming intoxicated with the ecstatic peak that seemed to swallow up all of his consciousness, and his manly juices spurted out from his manly, swollen penis.
"Hafu, ah, the pure white juice from Onii-sama's dick... this is the stuff that makes a baby. Semen, the precious juice that will make Onii-sama and Mel's baby, ahaha♪"
The white liquid gushed out with such force like an eruption, pouring down not only Leon's own stomach, but also Mel's, and her pubic mound and crack, which were covered with thin blonde pubic hair.
The younger sister wise man gazes in fascination at the thing, which exudes a strong masculine scent, and without hesitation scoops some up with her fingers and puts it in her mouth.
"Slurp, slurp, slurp, lick, slurp! Mmh, hah, hah, this is the strongest taste of Onii-sama, semen really is the sexiest and strongest taste, bubbling, ngh, let it soak into every corner of your mouth. Make sure you remember the taste of Onii-sama in one go, hah, that's a sister's, a wife's, mm, bubbling, slurp."
The wise younger sister rolls the semen she has brought to her mouth as if gargling, and smiles as if showing off the generous lather that has formed.
The milky white liquid he had just ejaculated stained the mouth of his sister, who always spoke to him in a beautiful, gentle voice. Even though he told himself that he shouldn't, he couldn't help the indescribable excitement and satisfaction that welled up in his chest.
However, his erection, which could not be controlled by reason, was growing harder and harder, as if it was trying to push back against the slit that was pressing against it, even though he had just finished ejaculating.
"Mmh, ngh, haa, Onii-sama's semen tasted so good...♪ Hehe, I'm sorry. Your cock, it's not satisfied with just this, it's angry at Mel's pussy. It's twitching, it feels like it's hitting Mel's pussy... Hehe, I'm sorry for making you wait. But... I won't keep you waiting any longer."
Mel scooped up all the milky white liquid that had splattered in conspicuous places with her fingers and licked it up, then gazed with crimson eyes at the still-unshriveled rod and let out a hot, happy sigh.
What was he thinking? He looked up at Leon, trembling with anticipation and anxiety.
"I won't waste any more baby material. I'll have you ejaculate properly inside my pussy and let Mel drink it all up in my uterus. No matter how much I drink with my mouth, I won't be able to conceive your baby. Mel, I've gotten so caught up in becoming your wife that I've forgotten such important things... I'm sorry, Onii-sama."
"Wha... Hey, Mel! Stop it already!! No more sibling stuff..."
You are about to cross a line from which there is no going back.
The hero brother screams in horror, but his insane sister smiles happily.
"But, my brother says he wants to put his penis inside Mel's pussy, and that he wants to impregnate her. If it really wasn't allowed, it wouldn't get bigger. Mel, I studied these things in the forbidden book so that I could be a good wife."
Although not widely distributed, novels with sexual themes are widely available as entertainment and material for sexual conversation among commoners as well as aristocrats.
Leon himself has picked up the book to quell his uncontrollable lust, so it's no wonder that Mel has read it too.
"B-but, we're brother and sister..."
"It's okay. I told you so, brother."
Mel dismissed her brother's words and made a small snap of her fingers.
At the same time, a new tentacle grew from the floor, this time wrapping around Rion's waist.
"Ugh, me, meru... ugh."
"Mel has gained power. The power to escape from this stupid world that doesn't accept that you and your brother love each other."
Mel stopped talking and looked around the throne room again.
"The deepest part of the monster's territory... In this castle, no one will ever come to bother Mel and the others. So let's stay here forever... and make lots and lots of love. Lots of love, to make up for the times we haven't been able to make because we've been worried about what others think... ahaha, ahahaha♪"
"Th-That's not possible...!"
If society doesn't allow siblings to be together, then we should just get out of there.
Mel declares without hesitation, leaving Rion speechless.
The strong feeling that he was serious about this could be seen from his eyes, which had turned red.
"Brother, isn't it okay? Let's keep going and have a baby together♪ From today on, this Demon King's Castle will be Mel and my brother's love nest♪ This place is a paradise for Mel and my brother, where even those who are after my brother... even that sow princess's hands can never reach. Ahaha, ahahaha... Come on, let's love each other to our hearts' content, Onii-sama."
At last, her desire can be fulfilled. Mel's voice trembles with excitement as she slowly raises her hips and places her erect penis in the center of her dripping honey slit.
With a small, squishy sound, the hot, swollen glans of her penis dug into the labia minora.
The area around the glans is being stimulated and tickled by the opening of the vagina, eagerly awaiting the moment of defloration.
He finally takes his sister's virginity and engages in forbidden intercourse.
(But if I don't do that, Mel will... what will I do...?!)
His feelings for his sister as a man, his feelings for her as a family member, and his responsibilities as a hero.
With a mixture of emotions, Rion was unable to come to any conclusion.
Meanwhile, she began to move.
"Here we go, Onii-sama. Mel's first time... please take it♪"
The blonde-haired younger sister looks down at her defenseless older brother, a smile that seems almost insane on her face, as she bends down forcefully.
Squish, squelch, squelch, squelchgggg!!
"Haha, yeah!? Agh, my, Onii-sama's dick is so thick, yeah, mmm! It's so much stronger and harder than I imagined...haha, yeah!"
The erection sinks into the vagina, which is covered in nectar, with a dull sound.
The passage of flesh, which had never before welcomed anyone, was narrow and too cramped to accommodate the hero's brave, erect flesh spear.
Mel gasped in pain and raised her voice, but she still pressed her cute, firm ass against her brother the hero's waist, trying to somehow get him all the way to the base.
"I'm sorry, Onii-sama. It'll take a little while, but... hahi, I'll put it all in properly, nfu! Mel's pussy is this cock's wife, so it has to take it all in, hahi, ugh, mhmm!"
"Haa haa, Mel, ugh, ahhh."
In time with the younger sister wise man's voice, the hot mucous membrane of her vagina ripples deeper inside.
Rion writhes in pleasure as the movements that feel like his shaft are being sucked on give him, and with nothing else to do, he peers at the connection point.
The nectar that continues to drip like a waterfall is mixed with fresh blood, proof that her chastity has been broken.
"Mel's first time, I really..."
"Yes, that's right ♪ Mel had dreamed of the day she would dedicate herself to Onii-sama, and for the first time, her pussy has been torn apart by Onii-sama's cock... nfu, ah, like this, all the way to the base, hafu, s-so deep that it penetrates all the way to her uterus, kuuuu!!"
At the same time as the hero's older brother muttered, savoring the pleasure and regret, Mel let out a cry of delight and began rubbing her hips against his.
The shaft finally sinks all the way to the base, and is enveloped in a vaginal mucosa that is so gooey it seems to have melted and turned into liquid.
Her flesh wriggles as if sucking the erect penis with all its might, and even though it hasn't even moved yet, her lower abdomen is overcome by an insane pleasure that feels like it's going to explode.
"Mel, Mel, ugh, aah, uuuuh."
"Ahaha, we're connected... Look, look, Onii-sama! Mel has finally become your wife ♪ I'm so happy... I'm so happy, my pussy and hips are moving on their own ♪"
The younger sage placed both hands on her flushed cheeks, extinguished the light in her eyes, and let out a cry of joy.
Immediately afterwards, she began to move vigorously, bouncing her soft buttocks against her brother's hips.
Slurp, squish, squelch, squelch, squelch!
"Ugh... ugh! Mel, you're moving too much, agh, aaah!"
The sound of water leaking from their connection grew louder and louder, and the sound of his erect penis being stroked by the ceaselessly wriggling mucous membrane. The friction of the tightly gripping mucous membrane, as if licking the surface of his skin, gave him an ecstatic pleasure that almost made him lose his nerve in an instant.
As he gritted his teeth in an attempt to keep his consciousness from flying away, a weak and pathetic gasp escaped from his mouth, something you wouldn't expect from a hero who had defeated the Demon King.
"Big brother, what a cute voice ♪ Please immerse yourself more and more in Mel's pussy, my little sister's pussy ♪ It's fine, Mel's pussy is a place that exists only to please you, and to conceive your baby. Please thrust into me more violently, more often. I want you to do it so hard that it takes the shape of your dick and can't go back to its original shape."
Mel leaned forward little by little, thrusting both hands against her brother's chest, which she had thoroughly cleansed with her tongue earlier, and began to shake her hips vigorously, accelerating her movements.
Slurp, slurp! Snap, smack!!
"Huff, ahhh, hifaaahh! Yeeeesss, Onii-sama's cock is deep inside Mel, hitting my uterus hard, haheh, ahh, mffaaahhh ♪"
Mixed with the moans and loud splashing sounds, there was also the dry sound of the buttocks hitting the hips.
This made me realize even more vividly that I was having animal-like sex with my sister.
"Ugh, Mel, ha, it's intense, ugh, uuh."
The pleasure surges upon you with such force that you can barely breathe.
As I peered into the joining point, gasping for breath, the nectar that had been foaming vigorously from the friction between the rod and honeypot was turning an even redder color.
The violent thrusting without giving her time to get used to it may be causing increased bleeding from the hymen breaking.
"Mel, does it hurt?"
"Hafu, hmm, Onii-sama, I'm so happy that you're thinking about Mel even at times like this ♪ I can really feel that Onii-sama loves me, aha, ha ha"
"Well, there's a lot of blood coming out! Hmm, at least try to heal it with magic..."
"I can't do something so wasteful! This is the pain that commemorates the union of Onii-sama and Mel... haah, this, it's the most wonderful pain in the world! Just like when I gave birth to Onii-sama's baby, it's a pain that I want to feel forever, so haah, hmm, I want to feel it as much as I can and become one with Onii-sama, haah, kufaaahh!"
The younger wise woman seems to have lost half her mind as she gasps and screams, her eyes looking into the distance.
The inside of her vagina also contracts as if asking for it to be dug and rubbed more vigorously, and the stimulation of the glans digging into the walls of her flesh and bouncing back strongly heightens the sensuality of her brother the hero.
"Ugh, ugh, Mel, I'm like this...ugh, ugh."
Unable to think of anything to say, he could only look up at his sister dancing lasciviously.
Her spilling breasts sway seductively in time with her wild hip swaying.
Sweaty and slightly colored, it looked even more erotic, and for a moment my eyes were glued to it.
"Brother, you're curious about Mel's breasts, aren't you? Mm, please... touch them. I want to feel you in more places than just my pussy♪"
"N-no, that's not..."
I almost nodded for a moment, but I held back just in time.
Once you start actively seeking it out, there's no going back.
(I mean, my arms are tied...)
He glances down at the tentacles entwining his wrists and lets out a small sigh. If it weren't for the tentacles that are restricting his movement, he might have reflexively reached out for the twin spheres of enchantment.
"Hafu, hmm, ah, sorry! Those tentacles are in the way. Hafu, I'll help you now... nfu, haa, aah ♪"
The moment the younger sage sister spoke, having once again noticed her brother's gaze, the tentacles binding Rion's arms began to move vigorously, making a rustling sound.
"What is this... Wait, stop it! Whoa!?"
Controlled by the tentacles, he raises his arm and touches the breast in front of him.
Her huge breasts are so big that they don't even fit in the palm of your hand. The warmth that spreads gently and the softness that is as fluffy as freshly baked bread are far more comfortable than you can imagine.
"Ah, Onii-sama's hands... I'm so happy that my breasts are being made to feel good by the hands that have always protected Mel, mhmm! Please rub them hard, really hard ♪ Let me memorize the shape of your fingers ♪ Hurry, hmm, ah, ahaha"
Mel leans forward and aggressively presses her breasts against me.
"Ugh, no, that's no good. That's..."
Feeling the heavy bulge with the whole palm of my hand, I couldn't help but put pressure on my fingers. A light push made it sink in, but just as it was about to sink in completely, the resistance got stronger and it pushed back.
"M-Mel's breasts...these are..."
The texture and elasticity are so amazing that you'll want to keep rubbing it forever. Even though you know you should stop, you end up enjoying it as you knead it with the whole palm of your hand.
"Kunnnn♪ Ah, it feels good, it's amazing, Big Brother is caressing me, he loves me not as a little sister, but as a woman, I'm so happy... I'm cumming, mmm, I'm so happy I could cum any second just from touching your breasts. Haa, hahi!"
In time with the movement of her fingers, the younger sister shook her head, scattering the sweat from her forehead, and let out the joy that was welling up inside her without hiding it.
Each wrinkle of the vaginal mucosa squirmed vigorously, stimulating the shaft as if it were being gently bitten. When I sank deeper, my glans was buried in the dead-end wall, squeezing me so tightly that I could hardly breathe.
"Ah, there, uterus! Please hurry and deliver Onii-sama's semen to Mel's uterus. Let's make a baby ♪ A baby between Mel and Onii-sama, people who truly love each other ♪ Let's create a happy family with Mel that can't be made with a calculating sow princess ♪"
"Wait, Mel! It's not like the princess and I will definitely get married, so, ugh, ugh, please, please... hafu, haa, ugh."
He tries to calm Mel, who is burning with an extraordinary animosity towards Princess Victoria, but he is unable to stop her from burning up.
Her hips continue to swing faster and faster, the hem of her skirt fluttering wildly, and the walls of her vagina ripple repeatedly towards the back as if squeezing the penis.
"Big brother, rub me harder ♪ Big brother, shake your hips and desire Mel's pussy. Pound my uterus with your cock and make me pregnant ♪ Please turn Mel's little sister pussy into your wife's pussy, come on, come on ♪"
Mel panted, her mouth loose as if she had lost all sense of reason.
In response to that voice, the tentacles restraining the hero brother began to move again.
"S-Stop! That's... not allowed, that's just not allowed, it's not allowed!"
Despite her desperate cries, Rion's hips shook up and down as she was pulled by the tentacles that had wrapped around her. The thin tentacles wrapped around her hands, even down to each of her fingers, forcing her to knead her shapely breasts with such force that they almost crushed them.
"Kufuu♪ Yes, that's right, that's fine♪ Please do whatever you want to Mel, Onii-sama♪ Ahaha, I love you, I love you so much♪ Ahaha, everyone, watch Mel and Onii-sama make a baby♪ I'm so happy I want to show everyone we're becoming husband and wife, hafu, kun, haa, ahaha♪"
"M-Mel... Ugh, I-I can't do it anymore... Ugh, aaah!"
Slurp, squelch, squelch, squelch, squelch!!
In time with Mel's movements, he is forced to thrust his hips upwards, thrusting his meat spear forcefully into her cervix, causing her breasts to shake violently as he squeezes them.
The intensity of Mel's actions expresses the feelings she has harbored for her brother for many years. Leon blames himself for being happy about this, but he is overcome with an unbearable urge to ejaculate.
"It's okay, Onii-sama ♪ I won't let anyone complain ♪ So please do your best to impregnate Mel. Your cock is twitching, wanting to release lots of baby seeds into Mel's uterus ♪ Come on, hurry, hurry ♪ Inseminate, inseminate and ejaculate, present the proof of your marriage to Mel's uterus. Yes, I'm cumming, ahhh, Mel's cumming too! I want to feel your love lots, I'm cumming, I'm cumming, ahaha, I'm cumming and want to have you all to myself!"
The moment the younger sister sage's moans rose an octave, her vaginal jar pulsated violently, urging her shaft in. At the same time, a new tentacle sprouted from just below the older hero's waist, and before he could resist, he was forced to thrust upward with all his might.
Slurp, squelch, squelch, squelch!
The loud sound of the rigid penis scraping against the fleshy mucous membrane as it was inserted. The tip pierced the dead-end wall like a spear and slid into the warmer flesh chamber.
The pleasure of being passionately desired by his beloved sister. His entire penis was enveloped in a sweet tingling sensation, and he felt as if he was melting to the core. Even a boy who had overcome many hardships as a brave man could not resist this temptation.
"I'm coming, too, aaah, I'm coming, inside Mel... I'm, ahh, ugh!"
Zzzzz, zzz──zzzz, zzzz!!
As his shaft throbbed violently, the liquid desire that had been dammed up spurted out with raging force.
"Mm, uuh, ah, uh, it's going in, big brother's semen, Mel's uterus is filling up with the baby's essence, aha, ahhh, I'm becoming a bride! Mel's pussy, my bride pussy has become pregnant with big brother's sperm, ahhh, I'm cumming, I'm cumming, uuh!"
The wise younger sister twists her spine in time with the pulsation of the meat spear, and reaches an intense climax with saliva dripping from her mouth.
Her vagina tightens intermittently, as if to express the intensity of her climax.
The pressure was so intense that it felt as if even his erect penis was being crushed. It felt as if even the remaining semen stuck in his urethra was being squeezed out.
"Agh, uhh, me, meru... haa, haa... ah..."
"Hmm, Onii-sama... I'm so happy ♪ Now Mel and Onii-sama are husband and wife... heck, we won't let anyone get in our way anymore. We won't let anyone complain either. We'll be together forever and ever... aha, haha."
As his consciousness faded from the afterglow of his intense ejaculation, all he could hear was Mel's maniacal laughter. Leon didn't have the time to respond, and could only shake his shoulders.
(What am I doing…)
He lifted his head slightly and stared blankly at the connection point.
The intense friction had made her meat mouth red and engorged with blood. From there, a milky white liquid, stained pale cherry blossom-colored and mixed with the fresh blood of her virginity, began to spurt out.
He had defiled his sister, whom he had protected for so many years, with his own hands.
Although he should regret it, he couldn't deny that he was happy about it and couldn't take his eyes off the even more sensual connection between them.
"Ugh, ugh, ah... ah..."
I can't stay like this forever, I have to do something.
I thought so, but I was losing all strength in my body.
"Hehe, Onii-sama... I got some of your power along with your semen. I'll have to use some powerful magic from now on..."
"Oh, a big spell...?"
"Hmm... please wait a bit. I'd like to enjoy the afterglow a little longer... but it looks like customers are starting to gather."
Mel smiled meaningfully and stood up, enjoying the feeling of the penis slipping out.
At the same time, the tentacles that had been restraining the hero brother also disappeared, and an eerie silence spread throughout the area.
"My stomach is full of my big brother's semen... ahhh, mmm ♪"
She lovingly strokes her lower abdomen and hurriedly gets ready.
He picked up the axe staff of light that had been lying around and chanted some kind of magic, and all the blood that had been on him during the battle with the Demon King and the love juices that had stuck to him during their intercourse completely disappeared.
And then... as if waiting for something to happen, the large doors to the throne room opened.
"...Huh?"
When Rion turned around, he was left speechless by the sight that unfolded before him.
A high-ranking demon with distinctive black wings led the way, and monsters numbering more than the number of fingers on both hands and toes entered the throne room.
Although we had defeated many monsters before reaching this point, it seemed there were still some left.
"This is bad! Ugh, my, my body..."
"It's okay, Onii-sama. They don't seem to be enemies ♪"
Leon tried to muster up his limp body and get up, but Mel, smiling and without a bat of an eye, stopped him with one hand.
"They're not enemies..."
Just as Rion was about to ask what that meant,
One of the demons, who seemed to be the representative of the monsters, stepped forward.
"New Demon Lord, we have come to greet you. We all pledge our loyalty to you."
At the same time as these respectful greetings were spoken, the monsters all knelt down at once.
"Eh... Ah, a new Demon Lord..."
The hero brother hurriedly turned his gaze towards his sister.
"Hmm, this is a problem. I explained it to my brother, but Mel annihilated the Demon King who controlled you all, along with his soul. All I really took was his power."
Mel explains once again that he is not under the control of the Demon King.
However, the monsters remained steadfast, as if to say there was no problem.
"The soul has nothing to do with it! The title of Demon King is given to those who possess great demonic power. You have annihilated the Demon King's soul... No one else can claim it except you, who possesses such outstanding power. Please, I beg you."
Damon declared on behalf of the group once again, and Mel nodded with a smile.
"I understand ♪ Then there's no problem. If the monsters cooperate obediently, it will make it easier for Mel to move forward with her plan."
As soon as the younger sage said this, she raised her axe staff of light.
As he had declared earlier, he was about to use powerful magic, as his eyes began to glow crimson.
"Brother, please wait a moment... I'm currently preparing a love nest for you and Mel♪"
"Huh? That's..."
The moment Rion was about to ask, the entire castle began to shake violently.
"What... is that... an earthquake...?"
"No, it's just sealed to keep out intruders. Would you like to take a look?"
Mel explained to her brother, who was shouting in a panic, and pointed the tip of her staff of light at the ceiling.
A large mirror then appears, and the exterior of the castle is reflected in it.
"...Wh, what is this!?"
Countless tentacles, similar to the ones that had been binding Rion earlier, were growing from around the huge castle.
The tentacles grew rapidly and entangled all at once, swallowing the castle into a giant cocoon of tentacles, making it completely invisible.
"Wow, what incredible magical power... The new Demon King's power surpasses that of all previous Demon Kings."
The gathered monsters let out cries of admiration at the incredible magic displayed by the younger sister sage.
"Mel, what is this..."
"I sealed the castle to keep out any interference. I don't think anyone would have come all the way this far, but just to be sure ♪ This will ensure that no one can enter this castle... or this paradise where Mel and my brother can share their love."
After explaining this to her stunned brother, Mel turned back to face the monsters.
"Everyone, I have two orders from Mel, the new Demon Lord. Do not interfere with Onii-sama and Mel. Stop attacking humans and live quietly in the monster's domain. If you understand the above, please disperse immediately♪"
"Yes, I understand, Demon King Mel!"
At Demon's words as a signal, the monsters all rose to their feet, saluted, and hurried out of the throne room as ordered.
As she watched him leave, the younger sage smiled proudly at her beloved brother.
"With this, the battle with the monsters is over, and Onii-sama no longer needs to fight as a hero, so we can spend our married life in this castle in peace♪ Here, where no one will interfere just because we're brother and sister... let's live together in harmony forever. This is the place that humans are least likely to get close to... I thought of this as soon as I stole the Demon King's powers, as we could live in peace here. Isn't that a good idea, Onii-sama♪ Fufu, ufufu... ahahahaha!"
"Wha... T-That's not possible...!"
The light disappeared, and the younger wise woman laughed loudly with a look of deep sorrow in her eyes.
(What will happen from now on...)
After crossing the line with his sister, she ascended to the throne as the Demon King and he was imprisoned in the Demon King's castle.
A furious turn of events that is difficult for a tired mind to comprehend.
Leon shivered in shock, unable to bear the shock that felt like he had been hit across the head, and before he knew it, he lost consciousness.
