What is Mel thinking?
Leon was trying to figure out her intentions, being careful not to provoke her.
However, even now, more than a week has passed since his confinement began, and he still has not been able to grasp anything, and he continues to be at the mercy of his younger sister wise man - no, his younger sister demon king - who has unleashed her desires.
Today, too, it's the same.
"Hafu, mm, the smell of Onii-sama's sweat. Mmh, sniff sniff, ha ha, ah, it's wonderful no matter how many times I smell it ♪ I want to make it into perfume and wear it all the time... hafu, mmh, smooch, ha ha, it's a smell that resonates in my uterus, sniff sniff, ha, hafu ♪"
"Mel, stop sniffing. It's really embarrassing..."
"Hehe, it's okay. I mean... there's nothing embarrassing between a married couple, and you and Onii-sama do a lot more naughty and embarrassing things, don't you think... so, hmm, kiss, it's okay ♪"
Inside the stone bathroom, Mel, on all fours in front of her brother, pleads desperately, and replies in a sweet, moaning voice.
He leans forward and squints his eyes in ecstasy every time he exaggerates his snort.
His cheeks flushed and the hot tongue rubbing against his chest, the ticklish sensation made Rion arch his back and gasp for breath.
(I can't believe it got this far.)
Day after day, I couldn't achieve anything. Just as I was relaxing alone in the bath, thinking about what to do next, someone suddenly burst in and started washing my back.
Lately we've been eating and sleeping together.
However, I had never had anyone barge into the bathroom like this before, so I was completely at ease, but it seems I was wrong.
"Hmm, heh, Onii-sama's chest... it's strong and beautiful today too ♪ Haa haa... hmm, I'm so happy. I can tell that there's a little bit of Mel mixed in with the scent. Onii-sama is being dyed by Mel... I can tell by the smell that he's become Mel's husband. Kiss, haa, hmm ♪"
My beloved sister pecking at my chest and nipples with her cherry-colored lips, murmuring happily.
Naturally, she was completely naked, revealing her large white breasts that could barely be half-covered in the palm of your hand, as well as her perfectly shaped peach-like hips.
(Come to think of it, this is the first time I've seen Mel naked.)
They had made love many times, never even taking the time to take off their clothes.
When viewed without any obstructions, its boldness gives a different kind of excitement.
His chest, carefully coated with saliva by his tongue, tingled sweetly, and his cock began to grow steadily aroused.
"Does it feel good, Onii-sama? Hafu, mmm, hefu, I actually wanted to take care of you in the bath like this sooner but... kiss, haa haa, I've been busy with my work as the Demon King and other things... nfu, lick, kiss, haa haa"
"Well, the Demon King's job is... well..."
"Hehe, it's okay. It's just... I'm just showing Mel my power to those naughty children who don't follow Mel's orders and refuse to stop fighting with humans. That way everyone will obediently follow me. Creating a world where my brother, the hero, doesn't have to fight is Mel's job as the Demon King and my brother's wife... so I'm doing my best♪"
Saying this, Mel raised her face and gazed intently at her brother with eyes that had lost their light. Her flushed cheeks relaxed slightly as she smiled, and it was adorable, but at the same time it sent an indescribable chill down Leon's spine.
What does it mean to "show strength"?
Since they followed suit, it's unlikely they took a life, but at least it wasn't just a demonstration.
Even though he didn't ask specifically, I could really feel it.
It's good that there will be no more conflict between humans and monsters, but she will do anything to keep him trapped here. I once again realize just how determined my younger sister Demon Lord is.
"Onii-sama, please rest easy and relax. Mm, that feels good.... hmm, I'm going to wash your body nicely now."
Mel ran her lips and tongue over his chest again, then picked up a small bottle beside him with one hand.
She then pours a sticky, slightly reddish liquid into the gap between her breasts and immediately leans forward.
"First, the thighs... hafu, mmm! Like this... squishy."
Mel begins to sway back and forth, her voice booming with joy.
As she moved, her breasts, now covered in stringy mucus, rubbed against her brother the hero's thighs.
Slurp...squish, squish, smear...
As her breasts slide against the water, the obscene sound of water echoes loudly in the bathroom.
"Ugh, ugh! Mel, it tickles, ugh, ahhh."
Her mucus-covered breasts smoothly stroke over her thighs.
Usually, there's a moist, sticky sensation that pulls you in, but today, there's just a warm, fluffy, soft feeling that slides over you.
Now that she had experienced the intense pleasure so many times, it was frustrating, and she instinctively lifted her hips, seeking even stronger stimulation.
"Hehe, big brother, if you move I won't be able to wash you properly."
"N-no, why would you want to wash there, ugh... ha ha, mmm!"
"A sponge or the palm of my hand isn't enough to wash my brother's body. I thought it would be best to use the softest and fluffiest part of Mel's body."
Mel looked up and answered with amusement, while both hands squeezed her sticky breasts together. They were two long, oval-shaped mounds. The valley in the middle, from which the sticky liquid was dripping, was suddenly pressed hard against his crotch.
"Ugh, ugh!"
His erect penis, already standing straight up, was now sandwiched between the soft flesh.
The marshmallow-like softness and exquisite elasticity give just the right amount of pressure to the entire trunk.
It was a much softer and gentler sensation, completely different from the tightness inside the vagina.
Just like when he had been caressing his thighs earlier, the stimulation was a little too strong for Leon at the moment, making his penis ache even more and his breathing inevitably become heavier.
"Haa, uuh! This... haa, haa."
"Your penis is the most important part of your body, it's what loves you, Mel. Mmmm, haa, you have to wash it carefully. Haa, haa... mmm, kufaaa♪"
The younger sister demon lord's eyes, now dark, narrowed in ecstasy, and as if to express her arousal, she buried her fingers deep into her breasts and began to boldly knead their bulges.
Her breasts changed shape irregularly, stimulating the erection of her cleavage each time.
Just when I thought the pressure was getting stronger, it quickly subsided. Just after the tip was tightly wrapped, the sides were gently caressed by the hot skin of my breasts.
"Ugh, it's no good, Mel. I, I can't take it anymore... haa haa"
"It's fine, don't be shy. It's natural for a wife to take care of her husband. Using my body to serve you like this is just one of my duties."
The hero's face contorted as he desperately pleaded, feeling a numbness in his entire lower body.
Mel looked up at it in ecstasy, but instead increased the strength of her fingers digging into her breasts, and began to shake her breasts boldly and violently.
Squelch...squish, squish, slippery.
The friction between their skin makes the mucus hotter and thicker, creating a loud, lewd sound.
In the valley between the twisted and crushed twin hills, his stiff penis is handled rapidly.
No matter how hard I press, there's no crazy pressure like there is with a vaginal jar.
The slippery mucus creates a gentle, faint sensation as if the skin is being rubbed.
That's why pleasure slowly wells up from the roots.
Mentally, I feel like I can't take it anymore, but my body can't keep up.
Unable to think of anything to say to stop his sister, he simply surrendered himself to the breast sponge and thrust his hips up and down in an attempt to increase the stimulation even just a little.
"Ahah, ah... I'm so happy to see Onii-sama feeling good with Mel's breasts. Hehe, it's the same as when I massage your arms and shoulders after chopping firewood... no, it's even more ecstatic. I'm so happy... nfu, ha, just looking at it makes Mel feel good too, ha, aha, ha ha ♪"
My beloved's breathing gradually became heavier, and he kneaded her breasts more roughly to match her.
Her bulge changes shape like bread dough. Her cute, pointed nipples are concentrated in the center and rub against her brother the hero's abdominal muscles, greedily devouring the pleasure.
Rion, who was being rubbed against it, also felt a pleasant tickling sensation from the hard flesh, and finally his physical excitement caught up with the mental excitement that made him want to ejaculate.
"Kufu, uhh, it's coming out... already, ha, hagh, aahhh."
"Are you about to cum? That's a problem... I went to so much effort to get it clean, and now it's going to get dirty again. But, being able to give you lots of pleasure is what makes Mel happy... it's what makes a wife happy. So please, haa haa, let lots and lots of cum come out ♪ Stain my breasts and face with your scent... nfu, fufu"
Hearing her brother's voice mutter uncontrollably, the younger demon lord's flushed cheeks relaxed slightly as she smiled, boldly shaking the breasts she had been squeezing.
Rion's thighs, coated in the mucus, bounced around, making a loud jiggling noise as her breasts swayed. The friction on his shaft had weakened because it was already covered in the mucus, and his movements were accelerating.
Squeak, squish, squish, squish, squish!
The mucus mixes with the pre-ejaculate fluid overflowing from the glans and foams into a creamy white liquid.
As it slowly seeped into the skin of his shaft, his shaft became burning hot, and his pleasure nerves became so sensitive that they reacted to even the gentlest stimulation.
"Ugh, haa haa, uhh, Mel... I'm... ugh, ugh!"
Unable to offer any resistance, she was simply swept away, moaning and writhing in agony.
Even as he pondered how pathetic he was and how sorry he felt towards Mel, Rion couldn't stop the sweet numbness that was building up from head to toe as his consciousness began to fade.
The trunk swells as if pushing back the mounds that are being pressed down on from both sides.
The whole body began to twitch repeatedly.
"Haa haa, please, Onii-sama! On Mel's face, on my breasts... nfu, Onii-sama's hot juices, please pour lots of semen that has become so thick from being excited by Mel♪"
"I'm, I'm, I'm coming, uh, uh!"
Splat, splat, splat! Splat, splat!!
Pushed back by his beloved sister's frantic pleading voice, the erect penis buried in her breasts pulsates violently.
A huge amount of liquid spurted out from her gaping opening, overflowing like an eruption and quickly staining Mel's face, which had her eyes closed in ecstasy, and her breasts, which were being kneaded.
"Please let out more, more, Onii-sama...♪ Hehe, I feel like the amount of semen you're letting out into Mel is gradually increasing. It's going well, it's going well... nfu, hehe."
Panting sweetly, occasionally sticking out her tongue to lick and taste the thick male juices that splashed onto her mouth, the younger sister demon lord's spine trembles with excitement.
As Rion gazed upon her, his erect penis, still wrapped in soft, elastic breast flesh, pulsated and continued to spurt out semen.
"Haa haa... Ugh, uh... I..."
I climaxed on my beloved sister's breasts, my whole body covered in my own color. A sense of forbidden pleasure and satisfaction filled my heart, but at the same time, an indescribable sense of helplessness crossed my mind.
The corners of my eyes start to get hot and I can't help but feel my eyes watering.
"Hmm...Brother?"
The younger demon lord noticed something strange about Rion and frowned a little uneasy.
"Mel, why... why can't you do this? I, your older brother, have defiled your younger sister Mel like this... taking away her future, her happiness. And yet..."
In a strained voice, he repeats what he has said many times before.
Mel was momentarily intimidated by the emotion in his voice and fell silent.
However, he immediately looked up and asked me again with anxious eyes.
"Brother, is it that hard for you to be united with Mel?"
"it is..."
"Mel has been by your side more than anyone else. I can proudly say that I love you more than anyone else. I have always... always lived my life thinking only of your happiness. I'm not like those people who just use you..."
Staring at the bowed Leon with her blue eyes, his beloved little sister desperately pleads with him about the strength of her feelings.
It's clear that her words are genuine.
A love so strong that it surpasses even the Demon King's soul. He is truly happy that she cares so much for him. But even so, the hero brother could not give up on his wish for his sister to find happiness in the light of day.
"...got it"
Mel muttered calmly, took her hands off the breasts she had been squeezing, and immediately stood up. Her penis was released from her wide cleavage, trailing many threads of milky white liquid and mucus.
His stiff penis is still trembling from the afterglow of pleasure, showing no signs of softening.
Despite his words, Rion found himself yearning for his sister, which seemed to reveal his feelings that he could not hide, and he felt ashamed, so he bit his lip.
Even though the bathroom was steamy, I felt a chill run down my spine, as if the temperature had suddenly dropped.
The uncomfortable atmosphere continued for a while - and then...
"If you're not needed by your brother... then you don't need Mel anymore."
The younger demon lord looked down at her older brother, muttering indifferently with an emotionless doll-like expression.
"I-I don't need it... What does that mean?"
"I mean it. If Mel's existence gets in the way of the happiness you seek... then Mel will disappear. If Mel, who possesses the power of the Demon King, is no longer with us, then I don't think you, the hero, would be called upon to fight such a harsh battle as this one."
Mel stopped talking and suddenly grabbed Rion's wrists with both hands.
He pulled it towards his neck.
"So please erase Mel with your own hands, big brother. Mel will be very happy if you can erase her, my dear big brother. Now... please."
Mel presses her brother's palms against her neck as if to say to strangle him, and smiles sadly with her eyes void of light.
The hero brother, who had been taken aback by the sudden action, came back to his senses when he felt the pulsation of the veins in his neck and hastily shook his head.
"Don't even say that as a joke! There's no way I'd kill Mel..."
"Because Mel wishes for her brother's happiness more than anyone else. She wants to eliminate anyone who gets in her way. Even if that person is Mel herself..."
The younger demon lord calmly retorted without even batting an eyebrow, and gripped her brother's wrist with force.
I want to be strangled with that same force. I could really feel that dark thought.
Rion felt so helpless that his mind went blank.
"Stop messing around!"
The next moment, he yelled loudly and shook off Mel's hand with all his might.
With his free hands now around her waist, he quickly hugged her tightly as if to say he would never let her go.
"You have no idea how much I care about you, Mel...! We're the only two family members I have. Please, even as a joke... don't say things like that!!"
Unable to contain his own passion, he couldn't stop his voice from gradually trembling.
Tears fall from her eyes, but she hesitates to let go of Mel's hand to wipe them away.
If I let go of her arm even for a moment, she would disappear somewhere. This indescribable anxiety welled up inside me, and I couldn't shake it off no matter what.
However, his beloved sister offered no resistance and simply silently leaned her body against her brother's chest.
"Your words... can I believe them?"
"Of course!"
"...Laughs, hehe, uhuhu... ahaha, ahahahahahahahahaha♪"
Immediately after I retorted with a firm answer, a high-pitched, ecstatic laugh began to leak out from my beloved sister's mouth, who had been rubbing her flushed cheek against my chest.
What started out as a low voice gradually grew louder and louder, eventually echoing throughout the bathroom.
"M-Mel...?"
The indescribable force left Rion speechless.
Mel raised her head in response to the voice, and was smiling broadly, as if to deny the emotionless, frozen expression she had had earlier.
"I'm so happy. So Mel and Onii-sama are truly destined to love each other and desire each other from the bottom of their hearts! I believed that from the beginning, but hearing your words made me even more convinced!!"
"Eh, th, that's..."
"I understand. You're just too serious, Onii-sama, and you're worrying about a lot of things and can't be honest with yourself, right? If that's the case, then don't worry. Mel will solve all of that."
The delighted younger sister demon lord said as she reached her right hand towards Rion's crotch.
The afterglow of what had just happened hadn't completely worn off, and his erection remained hard. When the area covered in the milky white liquid and the mucus that had been smeared on it was rubbed, a lewd sound immediately rang out, accompanied by a sweet tingling sensation.
"Mel, what are you trying to solve? That's... mmm!"
The brother hero asks, his spine trembling as his still-sensitive flesh is stimulated.
He had just threatened her with his life, so she couldn't just strongly reject him and pull away.
Mel looked up from her brother's chest, who was unable to resist, and with a happy smile on her face, she raised her hips.
"Mel is thinking of various ways to help you make up your mind, Onii-sama. So, for now, please trust Mel and cooperate. This hard, fine cock... let me wash it nice and clean with Mel's pussy ♪ Just like before, no, even more vigorously... hafu, I'll wash it nice and smooth. I'll slurp and rub it a lot, hah!"
With a trembling voice, the younger demon lord slowly lowered her hips, and her wet nectar came into contact with the head of her penis with a clicking sound. Her labia minora, completely melted and coated in nectar, were more sticky and moist than usual. She had probably put that mucus in there as well.
The tip of his rod is sucked by the slightly trembling, spreading flesh, and it sinks in little by little.
The area around the tip of her vagina kissed the opening, which was opening and closing slightly - and at that moment,
Slurpppp, slurp, squelchppppoooo!
"Ohhh, ugh! I'm inside you again..."
The younger sister wise man's vaginal cavity suddenly lowers her hips and swallows up his entire erection.
My sister's cute, firm hips came into contact with my thighs, and the smooth, spherical skin of her buttocks pressed hard against mine, flattening it and bringing us even closer together.
The glans digs deep into the inner wall of the vagina and is sucked greedily by the actively wriggling cervix.
"Haafu, Onii-sama's cock... No matter how many times I welcome it, it feels so good that my mind goes blank, and I'm so happy ♪ I'm sure Mel and Onii-sama were born to become one like this. I'm sure that's true, this feeling. Mmm, hafuu ♪"
My beloved sister smiles, her eyes squinting in pleasure as she is penetrated.
With the threat from earlier still fresh in his mind, the hero brother was now even more unable to think of the words to stop her rampage than before, and could only tremble his lips helplessly.
"I'm going to rub it nice and clean now. Mel's pussy gets so wet that it quickly becomes sticky when I think of Onii-sama, and a lot of love juice comes out... Afu, I can clean your cock in no time. Mm, ha, like this... ha, ahii, ahn!"
Squish, squish, squish, slosh...!
Mel lets out a sweet, nasal voice as she begins to swing her hips rhythmically and quickly, bouncing her buttocks like a ball.
Perhaps because I was thinking about "washing," the boiling hot vaginal mucosa was sticking tighter than usual to the skin of my shaft. As I went in and out, the countless wrinkles on the surface licked and rubbed me, and it felt as if the mucus and milky residue that had been smeared there were being scraped off.
It's as if a thin layer of skin has been peeled back, exposing the pleasure nerves. Before I could catch my breath, a sweet numbness ran through the core of my rod, and I was soon overcome with an excitement that made my spine arch.
"Ugh, haa, Mel, mmm, uhhh."
"It's always been my dream. If I could become a married couple with Onii-sama, we could take a bath together like this every day... hmm, so we could wash each other's bodies. When we were little I would only wash your back, but once I'm your wife I'll wash every inch of you... your penis, even your asshole. I want to wash everything, everything, clean... hafu, my dream has come true. I'm so happy, hmm, kiss, hmm!"
With her voice trembling with joy, the younger demon lord put her arms around Rion's neck and brought her face close to him.
As if wanting to share his excitement, he presses his lips against mine and thrusts his tongue into me.
"Mmhh, mmhh, hah, mel, ngh, sss, mmm!"
"Haa, hahi, I'll wash my tongue too, mhmm! With Mel's tongue... mmm."
As the sweet saliva was rubbed against the surface of his tongue, the hero brother felt as if his mouth and nose were being saturated with the scent of his beloved sister, and his mind began to melt away in ecstasy.
The shock of his sister demanding that he erase herself must have left him mentally exhausted. His will to resist had completely vanished, and he could only let her wash his body as she pleased.
"Every morning, Mel wakes me up with a kiss... mmm, haa, like this. Onii-sama is surprisingly a bit of a sleepyhead. Lick, haa haa, a kiss that just touches lips isn't enough. A kiss like this, mhm, intense... a kiss that makes my tongue melt ♪ Hmm, you like it too, don't you, Onii-sama? Kiss, mmm, aha, the kiss makes the cock inside my pussy twitch with joy, slurp, mmm, I'm so happy. I can feel Onii-sama's love!"
In between kisses, the younger sister demon lord talks impatiently and quickly about her plans for a happy future.
Just imagining such a married life seems to bring her to orgasm, as her vaginal walls tremble intermittently, giving further stimulation to her erection.
"Onii-sama, recently you haven't allowed Mel to hug you tightly and act spoiled. She says it's embarrassing when everyone is watching. But it'll be fine here ♪ There are only monsters around who can read the mood. Onii-sama and I will snuggle up together like a newlywed couple ♪ No, even after we're no longer newlyweds, I want to be snuggled up together forever. Like this... hafu, I want my whole body to feel Onii-sama's strong chest... ngh, haa, hann!"
As they continued to kiss intermittently, Mel leaned her body forward more.
Her breasts bounced and shook in time with the movement of her hips. The sticky fluid that had been applied to them, the semen that had been spilled earlier, and the sweat that was seeping out mixed together to make them glisten and shine, and they were pressed against the chest of her brother the hero with such force that they almost got crushed.
The feeling of her wet breasts caressing my chest skin in time with her hip movements was pale in comparison to having my sensitive penis squeezed and fondled, but it gave me a unique, ticklish pleasure.
"Ugh, ugh! Ahh..."
"Shu, ha, chuckle, it seems like Onii-sama has come to like using Mel's breasts as a sponge to wash his body. Mel's breasts belong only to you until your baby is born. Please enjoy them without hesitation... and make sure you feel good. Mm, ha, ah, I'm so happy ♪ I love that you're able to enjoy Mel's breasts, which have grown so big just to please you."
Staring at Rion, whose breathing was getting rough up close, Mel twisted her back and rubbed her breasts against him in a circular motion.
As her warm, fluffy breasts, like freshly baked bread, rub against the entire surface of his body, a sweet tingling sensation bursts across his skin, making the erect penis that is being held in her vaginal jar even more sensitive.
(My whole body is being washed by Mel's body... my sister's body. Being rubbed...)
The more I become aware of it, the more an indescribable joy wells up from the depths of my stomach.
"Ah, Onii-sama's skin is getting really hot. It feels good... Mel is feeling my breasts too... Hmm, ah, it's embarrassing. My nipples are so pointed... Hafu, but if my nipples get hard properly, it will be good because it will make it easier to feed my baby when he is born. I'll be a good mother. Haa, ahaha♪"
Mel's voice trembled with delight as she pressed her nipples, which had become hard and pointed from the friction, against Rion's chest. Occasionally they rubbed against her brother the hero's small nipples, and at those moments a particularly sweet stimulation reverberated all the way to the top of her head.
"Ahh, ugh... ha ha, uuh."
It was pathetic that he, the man and the older brother, was moaning against her chest. With such determination, he desperately tried to suppress the pleasure and endure it, but he couldn't stop his face from flushing.
"Fufu, Onii-sama, if it feels good, you can moan as much as you want. Mel will moan a lot too. So that Onii-sama's dick will get harder and harder, so that it will feel good... hahi, kuh, aha, haa, hyang♪"
The beloved little sister urges her brother, the hero, who is trying to hold back, and gradually speeds up the speed of his hip movements.
Her sagging breasts were caressed and rubbed all over my chest without giving me a moment to catch my breath, and the heat slowly spread to my core. It felt like my body temperature had risen all at once, and I naturally began to sweat.
"Hafu, the smell of Onii-sama's sweat is getting stronger. I love it so much, Mel. I'll let my scent soak into you, so please let your scent soak into Mel too♪ That's necessary for Mel and Onii-sama's happy future. So, hafu, ha, get hotter, sweat more... hahi, aah!"
"Ah, ahhh... hah, hah, ugh, ahhh"
The passionate encounter continues in the steamy bathroom.
Without being told by my younger sister demon lord, sweat was pouring out of my body. The sweat dripping from my forehead sometimes got into my eyes and was annoying.
Mel, who was urging me on, was also quite drenched in sweat.
Transparent sweat was running down her forehead and cheeks, and her messy blonde hair was soaked.
The scent drifting from there was sweeter than usual, and it seemed to permeate my entire body with every breath. I was so enchanted that I began to wonder if it contained some kind of aphrodisiac, and I couldn't stop my erection from spasming virilely inside her vagina.
"Hafu, haa, ah! Ah, I love you, Onii-sama... hafu, haa, for you, Mel will offer up her life, her body, her breasts, her uterus, everything, everything! Mel lives only for you, she is your wife. So, love me more, love me more, feel me lots... ngh, haa, I love you, hahi, haa, hahiiii ♪"
Mel expressed her wild feelings with a faraway, ecstatic gaze, then lifted her outstretched leg and clamped it around her brother the hero's waist.
He thrust his hips in forcefully, and his meat spear plunged deeper than ever before.
"Hmm, ah, it's deep, s-filling my uterus, hmm! Haa, Onii-sama, please keep cumming, s-splashing, haa, kuhah, aah!"
With her legs tightly wrapped around her brother's waist, the beloved little sister rubs her pubic mound, covered with a thin layer of blonde hair, against her belly button, begging for deep penetration and ejaculation.
The glans, buried in the dead end, began to move as if gouging at it, forcing open the slightly opening of the cervix and burying itself all the way inside.
The tightness felt at the sensitive tip was so strong that it almost took my breath away, and the erection that had been thoroughly licked and rubbed by the vaginal mucosa was unbearable.
"Mel... mmm, haa, uh, ahh... I'm cumming... ahh, ahh"
"It's okay, you don't have to hold back today. I've already rubbed my scent in plenty, so give me your semen. Mel's... I want you to pour lots of it into my brother's wife's uterus ♪ Mmm, I'm cumming, Mel too, I want my uterus to be hit by your brother's semen... I'm cumming, haaaah!"
When Rion groaned, feeling that he had reached his limit, his younger sister Demon Lord responded with a smile and put strength into her legs.
Her hips are pulled in tight and she sinks deep enough that her labia and the base of his shaft come into contact.
The tip of his penis was firmly seated in the cervix, and as if taking that as a signal, the entire vaginal jar began to convulse deeply. The stimulation of his hard, swollen shaft being rubbed against it easily snapped the thread of his brother's endurance.
"Uuuh, I'm cumming, ugh, ahhh, I'm inside Mel again... ugh, aaahhh!"
Splat, splat, splat, splat, splat!
The next moment, hot liquid spurts out from the tip of her penis, accompanied by a pathetic moan and a loud popping sound.
"Ahh, it's amazing, it feels so good, Onii-sama ♪ Onii-sama's semen smells good, lots of it is squelching into my uterus, I'm cumming, Onii-sama's semen is making Mel cum too, I'm cumming ♪"
The younger demon lord, who received it, also let out a lewd cry that aroused her brother, and her entire flesh channel contracted, squeezing his erection as she reached orgasm.
A few strands of blonde hair stuck to her sweaty forehead, and she gasped in ecstasy.
Her beauty is so sensual that you can't help but stare at her. As Rion is immersed in the pleasure of ejaculation, he can't take his eyes off his beloved sister's face.
"Ahh, hah, I'm so happy. Having Onii-sama watch over me as I cum, it's so reassuring, hah, so I can cum with all my might, all the way to the amazing place... haheh, I'm cumming, not yet... nfuh, hah, kufaahh, haheh, mhmm!"
Along with her high-pitched moans, transparent droplets spurt out from the edge of her honey slit that is gripping the shaft of meat.
Her legs wrapped around his waist began to spasm, and at the same time her vaginal walls began to swell. This told her brother, the hero, that she had reached a higher climax.
"Haa haa, Mel... ugh, haa haa..."
Watching his beloved sister's lewd behavior, and bathing his stomach in the sweet and sour scent of her semen, Rion continues his mind-numbing long ejaculation. Even when it finally subsides, her vaginal mucosa clings to his shaft, and she continues to spasm repeatedly, as if begging for more semen.
"Kufu, haa haa... afu, fufu, there's so much semen... I'm so happy ♪ With this, we've come one step closer to a happy future for Mel and Onii-sama. Lol, fufu, ufufu..."
"A happy...future"
What is the true meaning of those words?
Finally, the younger sister demon lord unwrapped her legs from around his waist and stood up, then placed the small bottle that was nearby against her vagina and caught the semen that was gushing out.
This behavior is often seen after sexual intercourse. There must be some special meaning to it.
"Soon... It's almost here. I will put my brother's sorrows behind me and become a real couple with Mel. That day... Ah, I'm really looking forward to it ♪ I can't wait..."
Surrounded by steam, my beloved sister stares at the small bottle filled with semen with an ecstatic expression on her face.
It's glamorous, and somehow terrifying.
Above all else── he muttered, before finally peeking out his tongue.
It's one of her habits that she has had since she was a child, and it's something she does when she's thinking of something mischievous.
In the past, they were all cute things she made to attract the attention of her older brother, who was busy supporting the family and didn't have much time to play with her.
What she's planning now is essentially the same.
However, this time it's not just a matter of attracting attention, but something huge.
(Mel…)
There was no way he could harshly question his sister, who had just pleaded with him to get rid of her with his own hands if she was getting in the way.
Leon could only stare at Mel, who was staring at the vial and smiling.
Then, three days passed in the blink of an eye.
"I wonder what's going on in the royal capital."
As usual, he finished his meal with Mel, and was on his way back to his room after saying goodbye to her as she was going to finish up her duties as the Demon Lord.
Rion glanced out the window, which was still filled with tangled tentacles, and muttered.
Quite a few days have passed since Mel ordered the monsters to stop fighting with humans.
It wouldn't be surprising if news of the change in the monsters that had previously attacked people mercilessly had reached the royal capital by now.
"You can probably imagine that it was because I defeated the Demon King. But, since I never returned, we ended up killing each other... or so they probably think."
Perhaps that's how it ended.
I think of Princess Victoria, who saw me off with a gentle smile as I departed.
(I wanted to at least say hello.)
They were so concerned about us that we ended up worrying them.
I feel bad thinking about it, but there's nothing I can do about it now.
"What should I do?"
I stopped and looked up to the sky.
Ever since the day he threatened me in the bathroom a few days ago, I've been unable to persuade him any stronger than I ever have.
He goes with the flow and spends his decadent days with her skin on skin.
It felt good and satisfying, but I wasn't yet ready to give myself over to it.
(Still, I'm curious about Mel's plan. What is it?)
There's no doubt that he's secretly planning something resembling a ritual. What could it be? The key to solving the mystery is that it's something that makes you decide to do it.
"It can't be brainwashing magic or anything like that... No, it can't be..."
He couldn't imagine that his younger sister, the Demon Lord, who loved him so much, would do something that would harm his mind and body. But what about other people?
Destroy this troublesome world and leave just the two of you.
It cannot be denied that he may be feeling that bad.
"N-no, if that were the case, then as a Demon King, I wouldn't be ordering the monsters not to start pointless fights. On the contrary, I would be proactive in motivating the monsters..."
I desperately try to stop my imagination from going in the wrong direction and think about it again.
What caught my attention was a thick old book that Mel had been frequently looking through since becoming the Demon Lord.
He always glances over before and after interacting with me, checking for something.
(Is that a book about rituals? If so...)
Immediately after thinking that, I saw a skeleton in butler uniform approaching from the front.
"What's the matter, Hero?"
"Oh, Mr. Bourne. Um, well..."
Immediately after he hesitated, Rion suddenly had an idea.
Right now, Mel is probably in the throne room, working hard on his duties as the Demon King.
When we parted ways at the cafeteria earlier, he wasn't carrying that thick book.
In other words, it's either in Mel's room or in the archives. At the very least, it's not in Mel's possession.
Now you might be able to check the contents.
"Hero?"
"Um, Mr. Bourne, there's this thick book that Mel often reads, right? Do you know where it is now?"
When I asked him a direct question in a panic, the skeleton in the butler uniform stopped moving.
He is just a skull with no expression on his face, but the aura he gives off is one of deep thought with a difficult expression on his face.
"Hero, why did you do something like that?"
"Eh, well, that's, well..."
"As I have said before, I am deeply grateful to Demon Lord Mel for freeing me from the unwanted duties that my predecessor had forced upon me, and I have pledged my loyalty to him. I am prepared to work myself to the bone for Mel..."
"Yeah, I know that..."
Therefore, I cannot do anything that would be detrimental to Mel.
It was easy to imagine what the rest of the story would be, but the hero brother continued his appeal without giving up.
"Right now Mel seems to be overwhelmed and running off on his own. That's... no good. As Mel's older brother, I want to guide him on the right path."
Bone tilts the skull's face down as Leon stares straight at him.
"I understand what you're saying, Hero. However..."
With that said, the skeleton butler passed by.
The hero's older brother slumped in disappointment, thinking that it hadn't worked.
"Turn the corner ahead and you will come to the end of the road where the castle's library is. The Demon King often looks at the books on the shelves at the back right."
Without even turning to look at me, Bones muttered, the sound of bones rattling echoing.
"Huh?"
"The Hero cares for Mel-sama more than anyone else. I've come to understand that having served by his side for the past few days. If that's what you say, then that must be what Mel-sama needs. Please take good care of him."
"...Thank you, Mr. Bourne."
Bowing deeply to the skeleton butler with whom he had once fought, Rion ran off as fast as he could to the library he had been told about.
The room they arrived at was much larger than the one Rion had been given, with countless shelves crammed with books.
Frowning at the distinctive smell of dust, I headed towards the shelf at the far right that I had been told to go to.
"There are over a hundred books lined up on this shelf alone. The one Mel was reading was..."
I was overwhelmed by the number of books, which was greater than I had expected, but as I quickly looked through them, one book that was clearly thicker than the others caught my eye.
I immediately took it out and noticed that unlike the other books, there was no dust on the top.
This is the best proof that it has been read frequently recently.
"Okay... this is it."
Opening it and checking the table of contents, it appears to be a grimoire that compiles the various secret techniques created by successive demon kings. The bookmark string glued to the spine is tucked into a page in the middle. First, I open that page and check the secret techniques written there.
"This is... eh... th, that's it!"
The content is not manipulative or harmful.
However, it is effective in making the hero brother make up his mind.
"But you went to the trouble of doing something like this during the ceremony...! Mel... what are you planning?"
Upon learning the truth, Leon could no longer keep quiet and ran out of the library towards the throne room where Mel was likely working hard on his duties as the Demon King.
"Oh, big brother♪"
Mel sat down on the throne where the previous Demon King had sat leisurely when he first set foot here, and smiled at his brother the hero who had rushed in.
It seemed like they had just gotten some free time, as there was no one else around at the moment.
In the spacious throne room, just the two siblings were present. Rion walked quickly over and handed the thick book he had taken out of the library to the younger demon lord.
When Mel received it, her eyes widened in surprise for a moment, then she smiled mischievously.
"I guess you found out. I was thinking of giving my brother a surprise gift."
"A gift...are you talking about Mel and I's child?"
Rion confirmed with a trembling voice to his beloved little sister who spoke so calmly.
The page that the bookmark was on was about the conception ritual used to create the next generation of demon kings.
If she was to give birth to a child of the Demon King's bloodline, the mother's womb must be beautiful and possess the appropriate power.
However, monsters have a tendency to have children only with the same species. It would be great if by chance they could find a monster of the same species as the current Demon King, but it's not necessarily going to work out that way.
This ritual will resolve that issue and ensure that a child can be conceived between different species, even if the mother is a human.
They consume a secret medicine made from each other's bodily fluids for a certain period of time, and during that time they have sex several times, increasing their pleasure to the limit, and then use the semen and love juices that are released as a catalyst to create a special ink.
And on the night of the new moon, when darkness reigns, by performing the final ritual and having intercourse, they are guaranteed to conceive a child.
This sequence coincides with what happened to Mel after she was imprisoned in this castle.
"Yes. On our first day, even though I was able to receive Onii-sama's sperm, I was so sorry that I wasn't able to conceive that day... I was searching for a better solution, and then I found this. Hehe... I think it can be done without relying on a ritual, but being able to conceive a baby on a specific day is really romantic... doesn't it sound like it would make a great ceremony?♪"
Even when questioned by her brother, Mel showed no remorse and simply smiled happily.
"What is a ceremony?"
"It's Mel and my brother's wedding. I know you don't like formal things, but it's something every girl dreams of... so I really want you to be a part of it."
In contrast to the tense atmosphere created by her brother hero, the younger demon lord had a happy, pink air about her, and answered in a dreamy voice, placing her hand on her flushed cheek.
"We will prove our love then and there... and make two babies. I think it will create a much stronger bond than exchanging rings or pledging our love to God♪ Heck, first I wonder if it would be a boy or a girl. Which one would you like, Onii-sama? Mel... I'm having a hard time deciding, but I might be happy if it's a boy who's just like you. If it's a girl, I'll worry that she might take a little of you away. Ah, but it'll be okay. Mel, I'll be aware of my responsibilities as a mother♪ I wouldn't do anything cruel like being jealous of my daughter and treating her coldly. Because, a child who is descended from my beloved Onii-sama will be just as dear to me as you are. Hehe, I'll love you so much... so much♪"
The beloved younger sister's delusions run wild, as she tries to make up for what she has hidden from her brother until now.
Overwhelmed by her force, Rion was at a loss for words, but somehow he regained his senses, grabbed her shoulders with a grim expression, and desperately pleaded with her.
"Are you serious, Mel? Brother and sister having a child...that's not allowed!!"
"...Why? There are no people in this castle who would interfere with our business. Mel and her family won't be talked about behind their backs, and the children won't be persecuted."
"Th-But even so..."
It would mean that I would never be able to escape this castle and would live in the shadows for the rest of my life.
No matter how determined Mel is, is that really enough?
With that thought in mind, he gazes upon his younger sister, the Demon Lord - but.
"Mel wants to have a baby, big brother. I've said it many times, but other people besides big brother don't matter to Mel... they're just like pebbles lying around everywhere. If you give your blessing to Mel and big brother, we can be friends... but I don't want anyone who rejects me. If big brother wasn't a kind person, I'd want to get rid of them all!"
"Wait, that's not true..."
"I know. So, here... let's live together as a family in this castle where there are no obstacles. Mel has always, always dreamed of this day. To be united with my brother, give birth to many babies who will share our blood, and make up for the loneliness she felt when she was little by building a lively and happy home. Hehe, feeling my brother's love every day, surrounded by two children... how wonderful. I absolutely will not let anyone get in the way..."
Before you know it, the light in Mel's eyes has gone out, and she begins to make rapid-fire appeals with a troubled expression.
Though overwhelmed by her strong feelings, Rion doesn't back down and looks straight into her eyes.
"I also want to make Mel happy. So...!"
"So, you can't marry Mel? Brother... you don't want to marry Mel... do you actually hate Mel? I see... what is it?"
"That's not true! I don't hate Mel... Damn, why..."
An older brother who wants to give his son happiness that will be celebrated by everyone.
A younger sister who just wants to have her beloved older brother.
They care about each other, but at the core of it all, their thoughts don't match, and a heavy atmosphere hangs between them.
At that moment, hurried footsteps burst into the throne room.
"Excuse me, Demon King and Hero. We have just received a report from the Gargoyle army patrolling the forest. ...It seems that a large army from the Kingdom of Lavand is approaching this castle."
The siblings' eyes widened as they heard the words of the skeleton in butler uniform, bowing respectfully.
"Ugh, the army? Why..."
"Do you have any idea how big it is, Mr. Bourne?"
Mel stepped up to the side of the speechless hero brother and asked with a stern expression.
With his head still bowed, what came out of Bourne's mouth was an even more shocking truth.
"Around two thousand. The one leading the way is the first princess, Princess Victoria."
"...That sow princess is here to steal my brother?! I can't forgive her..."
The moment she heard that, Mel trembled and gripped the axe staff in her hand with such force that it seemed as if she was going to crush it.
Rion was momentarily overwhelmed by the force of the sound, but he quickly regained his composure and asked again.
"That must be a lie, the princess will actually come out in person. That's impossible..."
"This is a report from a gargoyle soldier who had previously infiltrated the royal capital, I believe that's correct."
"No way..."
Perhaps she judged it safe since the monster invasion had stopped. Even so, it was far too reckless for the princess to come to the front line, the Demon King's Castle, herself.
"Fufu, that thief!! As I thought, she was a terrible woman. To come all the way here to steal Mel's brother... I will never forgive her, I will never forgive her, I will never forgive her, I will never forgive her, I will never forgive her, even if I die... Ah, hahahaha, I will erase her... Everyone who gets in the way of Mel and her brother should just disappear!"
"Hey, Mel, calm down! Mel... Mel!!"
The younger demon lord's eyes widen as the light fades and she lets out a laugh filled with madness.
Leon frantically shook her shoulders, trying to bring her back to her senses, but once Mel's rampage was ignited, it seemed impossible to stop it.
"Mr. Bone, please gather all the monsters hiding around here into the castle. We'll barricade ourselves here and settle this once and for all! That's right, I won't let anyone else eliminate those who get in the way of Mel and my brother...all of them, all by Mel's own hands...hehehe."
"Understood, I will send a messenger immediately."
"Wait, Mel! Please calm down!!"
Having received his orders, Bourne bows deeply and exits the throne room.
Rion continued to plead desperately, ignoring this, but he was unable to stop the murderous laughter of his younger sister, the Demon Lord.
