Chapter 6.1: Taking Kujo's Younger Sister to a
Love Hotel
On Monday at the beginning of the week, Mizuki and I took advantage of
our respective club activities' break to head to a love hotel.
The hotel I chose to go with Mizuki was the one I had previously visited
with Karen.
As Mizuki found out last time, there's a risk of being seen by acquaintances
due to its proximity, but even so, it's the best place. More precisely, the
same room as that time is ideal. The atmosphere there is calm, and the view
from the window is excellent.
It's an ideal place for having s*x in a good atmosphere.
The problem was whether we could get the same room, but in this age
where the whole world is connected to the internet, you can reserve rooms
at love hotels online, so it's not an issue. Well, until I went with Karen last
time, I didn't know there was such a method. Experience teaches you
everything, yeah.
After school ended, we went back home once, changed into casual clothes,
and headed to the hotel.
Mizuki's outfit was simple, a white long-sleeved blouse and a black long
skirt. She wore non-prescription glasses and a beret to prevent being
recognized. Even though July was approaching, she was covering her arms
and legs tightly, probably to avoid attracting male gazes.
Her long black hair, tied in a ponytail at the back of her head, and her
slender, athletic body combined with her simple attire to create a refreshing
atmosphere. That's why, despite the long sleeves and long skirt, she didn't
look stifling.
Now, Mizuki, since meeting up with me, hadn't opened her mouth at all. It
was clear she was nervous about what was going to happen next, and she
seemed somewhat pale.
Even when we arrived at the hotel and entered the same room, Mizuki's
attitude didn't change.
She stood still like a statue at the entrance, not moving but also not trying to
run away, showing that she had resolved herself in her own way.
I called out to Mizuki.
"Don't just stand there, come here."
Standing by the window, I called out, and I noticed Mizuki's body
trembling slightly.
After a moment, Mizuki, with her head down, nodded slightly and slowly
came towards me.
I waited for Mizuki to come over and then suddenly opened the curtains.
Then.
"Waa..."
Mizuki widened her eyes in surprise and let out a sigh at the view from the
window. Seeing the good scenery seemed to have eased her tension a little.
I put my arm around Mizuki's slender shoulder and pulled her body close
with a firm grip.
"Kya!"
Mizuki let out a small scream and stiffened her body. She had a tense
expression, probably because she thought I would attack her immediately.
However, I didn't move for a while, holding Mizuki close. I looked out the
window, occasionally stroking Mizuki's shoulder over her blouse as if
remembering.
Mizuki glanced at me, puzzled. Although she clearly doubted my actions,
she seemed to understand that I wasn't planning to rush things and she let
out a sigh of relief.
"Nice view, isn't it?"
I spoke to ease her tension, and Mizuki hesitantly nodded slightly.
"...Yes, I think so."
"The beautiful scenery looks even better with a beautiful girl beside me."
When I said that, the pretty girl showed a troubled expression and looked
down.
I laughed softly.
"Oh, you're not going to agree with me?"
Teasing her while still holding her shoulder, Mizuki's cheeks quickly turned
bright red. If someone were watching us from outside the window, they
might think a young couple was flirting.
After that, I continued to stroke Mizuki's shoulder, touch her hair, hold her
hand, and praise her fashion today as part of our interaction.
Mizuki blushed more and more, but at the same time, her body gradually
relaxed.
When I felt the time was right, I leaned close to Mizuki's ear and said,
"Mizuki, I'm going to take off your glasses."
Without waiting for her response, I removed Mizuki's non-prescription
glasses. They looked familiar, so maybe she bought them with Karen.
I placed the glasses on the windowsill and looked at Mizuki, who seemed
somewhat dazed. The girl I had fantasised about taking her virginity just
seven days ago was now blushing and looking at me in a hotel room.
Just seeing her flushed face made my groin ache painfully.
"You're beautiful, Mizuki."
"Ah..."
I gently placed my hand on her chin and lifted it slightly.
My face was reflected in her clear black eyes. Mizuki slightly parted her
lips, perhaps by chance or maybe because she anticipated my next move.
As I thought about that, I tilted my face and pressed my lips against hers.
"Ah...!"
Mizuki's body jerked, and her lips tightened.
I had done many things to Mizuki before, but I had avoided kissing and s*x.
Because of that, Mizuki seemed unsure of what to do, shrinking her
shoulders.
I wrapped my arms around Mizuki's body, holding her firmly. I kissed her
gently, waiting for her tension to ease.
"Mmm... mmm... ah..."
Mizuki made muffled sounds, looking at me with a confused expression.
She probably came prepared to be treated more roughly today.
It was natural for Mizuki to think that way.
Until today, I had treated Mizuki quite roughly—rather, I had been very
careless with her.
I repeatedly compared her to Karen and belittled her. I forced this girl, who
probably didn't even know about kissing, to perform oral s*x on me.
Despite her lack of knowledge and skills, I relentlessly pressured her and
eventually stopped asking for her service, almost implying she wasn't worth
it. I even deliberately showered her with vulgar words like [dick] and
[pussy].
Since Mizuki had taken Karen's advice and changed her attitude, I stopped
treating her roughly. Still, Mizuki probably felt like a slave.
Of course, there was a reason for my behaviour.
Initially, Mizuki's hostility towards me was obvious, as was her clear
aversion to the opposite s*x. In that state, kissing her or hugging her gently
would have only increased her disgust.
With that in mind, I denied Mizuki at every turn. I repeatedly told her,
[Karen is having s*x with me for the sake of your brother], stirring up
Mizuki's guilt. By doing so, I aimed to crush her rebellious spirit and instil
the idea that [I must obey Makoto Kasuga for Karen's sake].
That plan worked. As proof, Mizuki voluntarily came to the hotel with me
and kissed me.
After pushing Mizuki to this point, my goal was to be gentle and attentive
today, creating an opening in her heart.
"Mmm... fu... mmm... chu... chu."
With each kiss, I could feel Mizuki's body growing warmer.
I continued kissing her, but after a while, I noticed a strained sound in
Mizuki's voice. She wasn't able to breathe properly because she wasn't
used to kissing. Realising this, I licked her lips and then stopped kissing.
Freed from the kiss, Mizuki hurriedly took deep breaths.
After calming down, Mizuki suddenly seemed to realise something and put
her hand to her lips.
"Ah... this was my first..."
"Was it your first kiss?"
When I asked, Mizuki nodded, her face turning bright red.
I tightened my embrace and whispered in her ear.
"It's an honor to be Kujo Mizuki's first kiss partner."
"~~~~!!"
Hearing that, Mizuki's earlobes turned crimson.
Her lustrous black hair reflected the sunlight streaming in through the
window, shining brilliantly. Drawn to it, I placed my hand on Mizuki's hair
and combed through it with my fingers.
Mizuki let out a nasal sound, seemingly enjoying the caress.
Excited by her voice, I urged Mizuki to lift her face while continuing to
stroke her hair.
"Mizuki, look at me."
"Y-yes... mmmph!?"
When Mizuki raised her face, I seized her lips more forcefully than before. I
sucked on her lips, making smacking sounds, and licked the surface of her
lips with my tongue.
Mizuki's expression showed surprise and embarrassment. I continued to
enjoy her changing expressions as I kissed her.
"Mmm... chu, chu... mmchu... ah, that's ticklish... mmm! Mmm... chu,
chu, chuuu♡"
Our lips melded together, and the lewd sounds of our kissing echoed in the
room.
Seeing that Mizuki wasn't trying to run away even at this point, I decided it
was time. I parted her lips and slipped my tongue inside.
When I lightly flicked Mizuki's tongue with the tip of my own, she quickly
retracted it in a panic. I then pushed my tongue deeper into her mouth,
intertwining it with hers.
The unfamiliar sensation of our tongues entwining made Mizuki's body
twitch.
Remembering the time Karen bit my tongue, I quickly withdrew my tongue,
gently stroking Mizuki's hair before lightly tapping her tongue again with
mine.
After a moment of hesitation, Mizuki tentatively touched her tongue to
mine.
Slowly, we intertwined our tongues.
"Mmm... mmchu... lero... lero...♡ Mm, chuku, churu... hamu, amu...
mmm, kuchu...♡"
"Mmm, chu... does it feel good, Mizuki?"
"I... don't know... It's like our tongues are rough and rubbing together, and
it's directly affecting my brain... I've never felt this before... mmph!?
Chu♡ Chu♡"
Even though she said she didn't know, Mizuki's face was clearly melting
with pleasure. When I entwined our tongues again, Mizuki couldn't help
but squirm.
From her reaction, it was clear that Mizuki was experiencing pleasure from
her first deep kiss. Perhaps her tongue was an erogenous zone.
With that thought, I continued to entwine my tongue with Mizuki's. As we
deep-kissed, her moans grew louder, and before long, her hands were on my
back.
"Phuah."
After thoroughly savouring the inside of Mizuki's mouth, I reluctantly
withdrew my tongue to move on to the next stage.
Mizuki was panting heavily, looking at me with eyes glazed over with
arousal.
I guided Mizuki away from the window and towards the double bed in the
centre of the room.
I told her to undress, and after a moment of hesitation, she responded in a
barely audible voice, [Understood...]
Under her simple blouse and skirt was a matching set of simple white lace
underwear. The shorts and the cups of the bra each had a black ribbon,
exuding both a youthful innocence and a touch of allure.
Her choice of underwear, which perfectly suited my tastes, made my breath
quicken.
I quickly stripped off my own clothes, hastily put on a condom, and pushed
Mizuki onto the bed.
Hovering over her, I resumed kissing her passionately.
At the same time, I let my hands roam her body. I squeezed her breasts over
her underwear, stroked her slit, and heightened her pleasure to ease the pain
of her first time.
As I continued to caress her, a wet, squelching sound began to emanate
from beneath her shorts.
Hearing Mizuki's sweet, melting voice, I judged that there would be no
issue with penetration.
"Mizuki."
"Mm, ah... yes?"
"I'm going to take off your underwear."
As I spoke, I placed my hand on her bra strap.
Mizuki, who had been moaning from the pleasure I was giving her,
suddenly lowered her gaze as if realising something.
Mizuki's hesitation lasted for a while, but she must have made up her mind
for this day. Soon, she looked me in the eye and nodded clearly.
"Yes, I understand."
With her consent, I quickly unhooked her bra and removed it, then moved
my hand to her shorts.
Mizuki raised her hips to make it easier for me to remove her shorts. I was
surprised by her cooperative attitude, but for Mizuki, it might have been a
natural decision once she had resolved herself.
Thinking it was just like the serious Mizuki, I removed her underwear.
Mizuki's exposed genitals.
I straightened up and spread Mizuki's knees, staring intently at her wet,
glistening slit.
"Uu... it's embarrassing..."
Mizuki covered her face with both hands, expressing her shame.
I considered teasing her about not covering her crotch, but my own arousal
had reached its limit, so I decided to skip the idle talk.
I grasped my penis and pressed the tip against her vaginal opening.
And then.
"Here I go, Mizuki."
"Y-yes――――ah, ku!?"
Mizuki's vaginal opening was smaller and her vaginal walls tighter than
Karen's.
Even though I had tried to loosen her up as much as possible, it seemed that
a virgin's body doesn't become soft so easily.
I thought it might be better to make her climax once first, but withdrawing
now to make Mizuki come and then re-entering seemed too roundabout.
More importantly, I couldn't hold back my desire to penetrate her.
I decided to continue with the intercourse as it was. Rather than dragging it
out, I believed it would be easier for Mizuki to be penetrated quickly. I
thrust my hips forward forcefully, pushing the tip into her vagina.
"Guuh! Ah, it... it hurts!"
Each time I gouged her insides with my tip, a pained voice escaped from
Mizuki's mouth. Her face contorted in agony, and her hands clutched the
bed sheets tightly, expressing her suffering with her whole body.
But I didn't stop my thrusting.
As mentioned earlier, I believed it would be easier for her to get it over with
quickly.
――There was also another, rather trivial reason.
I was excited by the sight of Mizuki writhing in pain from the loss of her
virginity. The realisation that I was taking the virginity of Kujo Mizuki, a
younger girl, and making her mine, filled me with an overwhelming sense
of conquest.
One week ago, I had fantasised about this after seeing the photos Karen sent
me and now I was making it a reality.
Soon, Mizuki would be panting on my shaft just like Karen. If possible,
even today.
That thought made my penis even harder and bigger, surprising even
myself.
"Ah, ah... it's getting bigger... why?"
Mizuki looked at me with tearful eyes.
I couldn't possibly tell her that I was excited by her suffering. Instead, I
gently smiled and stroked her cheek.
Mizuki's expression softened slightly as I stroked her cheek, despite her
groans of pain.
While this was happening, I felt something touch the tip of my glans.
Unlike the previous tight passage, there was now a clear barrier.
As soon as my penis touched it, Mizuki's vaginal walls tightened even
more. The contractions of a virgin were trying to crush my penis rather than
just tightening around it. It was as if I had clamped my penis in a vise.
Her vagina was screaming, [Get out], which was likely Mizuki's true
feeling as well.
Ignoring her silent plea, I said,
"Mizuki, I'm taking your virginity."
"...Uuuh... okay... I understand..."
Tears streamed down Mizuki's face as she nodded in pain.
Seeing her tears, my excitement peaked. With a powerful thrust, I broke
through the barrier that blocked my way.
Immediately.
"Aghhhhhh!!"
A scream filled with nothing but pain echoed through the room.
Mizuki's vagina tightened around my penis with crushing force. The painful
grip was proof that I had taken Mizuki's virginity, and the realisation set my
whole body on fire with an overwhelming sense of conquest and an intense
desire to ejaculate.
I couldn't hold back. I couldn't hold back. I couldn't hold back.
The primal pleasure of being Mizuki's [first man] burned through my brain,
and before I knew it, I was ejaculating.
The pleasure was so intense that my body trembled as if convulsing, and
my vision went white. I continued to spurt semen endlessly, feeling the
condom inside her vagina swell.
For the first time in my life, the pleasure was so overwhelming it felt almost
painful.
After some time, I finished ejaculating and slowly pulled my penis out of
Mizuki's vagina. With a popping sound, my penis came free, and a trickle
of blood, proof of her broken virginity, flowed from her vaginal opening,
staining the bed sheets.
Mizuki lay on the bed, panting heavily, utterly exhausted. Her face was
smeared with tears, snot, and saliva, but I found her beautiful nonetheless.
"Mizuki."
"...Yes?"
"You were incredible."
I kissed her on the lips.
What was meant to be a light kiss turned into something more as Mizuki
wrapped her arms around my neck and held me tightly as if not wanting to
let go.
Not only that, but Mizuki inserted her tongue into my mouth, desperately
intertwining it with mine. She was likely seeking the pleasure of a deep kiss
to distract her from the pain.
Smirking inwardly at her actions, I entwined my tongue with hers, giving
her the pleasure she sought.
For a while, the room was filled with the lewd sounds of our tongues
intertwining.
◆◆◆
Gentle, steady breathing has been tickling my ears for a while now.
It's the sound of Mizuki's peaceful sleep as she rests her head on my arm.
During our deep kiss, she suddenly collapsed into sleep as if exhausted.
I used the wet wipes from the side table to clean Mizuki's face and body,
then slid my right arm under her head to cradle it.
As I stroked Mizuki's hair and touched her body while she slept, she
occasionally let out sweet, contented sounds.
At times, though, her brows furrowed in discomfort, likely due to the
lingering pain from losing her virginity.
Although I expected Mizuki to wake up from the pain, she remained asleep
even as the sky outside the window grew dark.
Perhaps she hadn't slept much the night before. Considering her situation, it
wouldn't be surprising. I didn't notice any dark circles under her eyes, but
maybe she had concealed them with makeup.
Thinking about it, I didn't feel like waking her up. Though it meant losing
the precious time we paid a lot of money for, holding Mizuki like this was
quite a pleasant experience.
In the end, Mizuki woke up just before eight o'clock, when the sun had
completely set.
She slowly opened her eyes in my arms, looking at me with a somewhat
dazed expression—
"...Onii-chan?"
She addressed me in a soft, dreamy voice.
Just as I was about to respond, Mizuki suddenly furrowed her brows and let
out a pained sound.
"It hurts... why does my crotch... oh..."
She reached down to her groin, a puzzled look on her face, and then her
consciousness seemed to fully awaken, her eyes widening in realisation.
Several expressions flitted across her face, not all of which were favourable
toward me.
Earlier, Mizuki had given her virginity to me and had passionately
intertwined her tongue with mine. At that moment, she had undoubtedly
accepted me.
However, it was possible she had been swept up in the atmosphere.
After all, our relationship began with coercion. Once the excitement of the
affair subsided and she had enough sleep to reflect on everything, it
wouldn't be surprising if Mizuki harboured negative feelings toward me.
With that in mind.
"Mmmph!?"
I captured Mizuki's lips before her emotions could settle.
Naturally, I slipped my tongue into her mouth. Mizuki stiffened in surprise
but only for a brief moment.
When I teased her tongue with the tip of mine, she hesitantly started to
intertwine her tongue with mine, perhaps recalling our earlier deep kiss.
The tentative contact quickly transformed into a passionate deep kiss.
"Mmm... mmm... mm, chu... ♡ Ahmu, rero...rero... ♡ Haa... haa...
mmm, chu♡ Juru♡ Jururu♡"
Holding each other tightly, we pressed our lips together, intertwined our
tongues, and shared our saliva.
When I repeatedly performed the actions that Mizuki enjoyed earlier, her
eyes quickly began to glaze over with pleasure.
The look she gave me was filled with passion and desire, and the feelings of
rejection she had seemed to melt away. Deciding it was enough, I stopped
kissing her and spoke softly.
"Good morning, Mizuki."
I whispered gently, and Mizuki gave me a shy smile.
"Y-yes, good morning."
"I was quite rough earlier. Is your body alright?"
"Yes. Um, my crotch still hurts a little, but it's nothing serious."
Hearing that, I sighed in relief.
"That's good to hear. I would feel responsible if your first experience was
only painful."
"Don't worry. It wasn't just pain. It was very... pleasurable."
It was clear that this wasn't Mizuki's true feelings. She had suffered from
the pain of losing her virginity and hadn't even climaxed. Mizuki was only
saying this to appease me for Karen's sake.
However, getting Mizuki to say that her first experience with me was
pleasurable was significant. I smiled as I ran my fingers through her smooth
hair.
"I'm glad to hear that. Like I said before, s*x with you was incredibly
pleasurable."
"Thank you. That makes me happy too. Um, could we... continue kissing?"
"Of course."
I kissed Mizuki repeatedly, as she requested.
As mentioned earlier, it was already night. We had about an hour left at the
hotel.
Honestly, I wanted to have s*x at least two more times.
However, Mizuki still showed signs of pain in her crotch. While she might
not refuse if I insisted, I decided to prioritise her well-being over my
desires. Having treated her roughly until now, I planned to win her heart
with sweetness and care moving forward.
Having decided against further s*x, I decided to clean up the sweat and
bodily fluids by taking a bubble bath with Mizuki. The large bath, typical of
love hotels, was almost like a pool – though that's an exaggeration, it was
definitely larger than any household tub.
I enjoyed the feel of Mizuki's soft body as I embraced her from behind
while soaking in the water.
Incidentally, this room offered a view of the outside scenery even from the
bath. Caressing Mizuki and looking down at the city lights felt like I was
the king of the city.
Mizuki surrendered to my touch, occasionally letting out sweet sounds
while gazing at the view outside.
While enjoying this moment, I remembered something Mizuki said when
she woke up.
"By the way, Mizuki."
"Mm... yes?"
With her hair tied up to keep it from getting wet, Mizuki leaned against me
as she spoke.
I kissed her hair lightly before continuing.
"When you woke up earlier, you called me [Onii-chan]. Do you call your
brother that at home?"
I asked out of idle curiosity, not deeply thinking about it.
When I showed her the paizuri video in the clubroom the other day, Mizuki
called Kujo [Nii-san]. I was simply wondering if she called him [Onii-chan]
at home and [Nii-san] outside.
Mizuki blushed deeply, all the way to her neck, and looked down in
embarrassment.
"T-that was... um..."
"Oh, I wasn't teasing you. I was just curious."
With that reassurance, Mizuki took a deep breath and began to explain.
She told me that when she was in elementary school, she was stalked by an
unknown man. Fortunately, she wasn't physically harmed and the stalker
soon disappeared, but the psychological impact on young Mizuki was
significant.
She became so wary of strangers that she couldn't go outside for a while.
During that time, it was her brother, Kujo, who supported her. He stayed by
her side, protecting her, and Mizuki often relied on him, sometimes even
sleeping in his bed at night.
Mizuki spoke in a nostalgic tone.
"When I woke up, I felt like I was being held and protected by someone. It
reminded me of those times, and I just... called you that."
"I see, so that's what it was."
I nodded in understanding – though internally, I was displeased. I didn't like
that Kujo's presence was so deeply ingrained in the heart of my s*x partner,
whose virginity I had taken.
Of course, it was unavoidable. For Mizuki, when comparing a man who
blackmailed her into being his s*x partner and the brother she had lived
with for years, it was obvious who she would cherish and rely on. It wasn't
even a contest.
But that didn't make it any less annoying. As I fondled Mizuki's nipple, I
whispered in her ear.
"You and your brother are very close, aren't you, Mizuki?"
"Hm♡ Ah, y-yes♡ But... ah♡"
"But what?"
"Since K-Karen-san and him started dating... ahh♡ he doesn't pay much
attention to me anymore... ah♡ haa♡"
As I toyed with Mizuki's nipple, I nodded thoughtfully.
It's natural that he would prioritise his girlfriend over his sister. Come to
think of it, did Kujo, who once protected his sister from a stalker, notice
that his sister was now being coerced by me?
The answer was obvious. If Kujo had noticed Mizuki's strange behaviour,
she wouldn't be in the bath with me now.
Understanding this, I asked Mizuki anyway.
"Did your brother not notice that you were being forced to be with me? Not
just today, but this whole week, did he not notice your odd behaviour even
once?"
"That... I..."
"If so, he's a pretty unreliable brother, isn't he?"
With that, I lifted Mizuki in the bath and turned her around.
Hugging her from the front, I kissed her cheek and continued.
"Mizuki, you're my s*x partner, right?"
"Y-yes..."
"When I call, you come running and spread your legs, you're my woman,
right?"
"T-that is..."
Mizuki hesitated, looking down, unable to answer.
I parted her lips and invaded her mouth with my tongue. Now that she knew
the pleasure of a deep kiss, she didn't resist.
After entwining our tongues thoroughly, licking her mouth, and sharing
plenty of saliva, I asked Mizuki again.
"Mizuki, you're my woman, right?"
"Ah...♡ Yes... yes."
Seeing Mizuki nod with teary eyes, I smirked and said,
"Good. From now on, I'll protect you instead of your unreliable brother. As
your new brother."
I pressed my lips to her cherry-coloured ones again, inserting my tongue.
After satisfying Mizuki with my tongue, I confirmed strongly.
"Alright? From today, I'm your Onii-chan."
"But... but..."
"Alright?"
I asked again in a firm tone. Mizuki couldn't resist any longer.
She responded in a barely audible voice.
"Understood..."
"Call me [Onii-chan] from now on, Mizuki. Understood?"
"O-Onii-chan..."
"Louder!"
"Onii-chan!"
"Good. That's right. You're my cute little sister."
When I patted her head and praised her, Mizuki made a sound like a puppy
and looked at me with affectionate eyes.
"Onii-chan...Onii-chan..."
Mizuki kept repeating [Onii-chan] over and over, rolling the words on her
tongue until she couldn't hold back any longer and started kissing me
hungrily.
Moreover, she began to rub her slit against my erect penis in the water,
moving up and down.
She wasn't ready for penetration yet, so she didn't try to insert it. Instead,
she applied the skill she had developed over the past few days with her
paizuri, providing pleasure with minimal pain.
Mizuki's sudden enthusiasm seemed to be a form of escapism, a desire to
avoid thinking about anything else and just feel good. It wasn't a sign of her
suddenly becoming obedient.
However, this worked in my favour. The more Mizuki sought refuge in
pleasure, the more dependent she would become on me. I was determined
to make her mine in every sense, drowning her in ecstasy.
"Chuu♡ Chuu♡ Chuuh♡ Lero♡ Lero♡ Big brother♡ Does it feel good?
♡♡ Does my body feel good?♡♡"
"Ah, yes, Mizuki. You're amazing. The best little sister."
"Ah, I'm so happy♡ I'm so happy, big brother♡ Feel even better♡ Big
brother♡ My big brother♡♡"
Mizuki's hips moved vigorously up and down, causing the water in the tub
to splash around.
With her loving deep kisses and the friction against my penis, my urge to
ejaculate quickly intensified.
"Mizuki, it feels so good. I'm about to come."
"Yes♡ Please ejaculate♡ Release lots of semen♡"
"Mizuki, come with me. Let's come together, alright?"
"Yes♡ Ah♡ Ah♡ Ah♡ Big brother, I'm going to come♡ I'm coming
too♡♡"
"Alright, come!"
I rubbed my penis against her clitoris with increased intensity.
Then.
"Ahhhhhh!♡♡ I'm comingggg!♡♡♡"
Mizuki cried out in the climax.
She clung to me tightly, biting down on my neck and digging her nails into
my back as if to endure the intense wave of pleasure. The sharp pain from
her nails digging into my skin triggered my own orgasm.
Ejaculating in the bath while gazing at the beautiful night view, with
Mizuki's pussy rubbing against me, was pure bliss. Even the thought of
having to scoop out the semen from the water later didn't bother me.
As I shook with the pleasure of release, I gently caressed Mizuki's back and
bit her earlobe lightly. The slightly stronger bite was a playful revenge for
her biting my neck and scratching my back.
Mizuki's body shuddered violently in my embrace, indicating she was
experiencing a second orgasm. Smiling softly, I continued to hold her.
Afterward, I whispered [You're so cute] into Mizuki's ear while gently
stroking her hair.
Chapter 6.2: Kujo Mizuki 2
"Aaaaah... What have I done...?"
Mizuki, who was sent home late at night by Kasuga, was writhing on her
bed.
Needless to say, what floated in Mizuki's mind was her disgraceful
behaviour at the love hotel.
She had prepared herself for having s*x with Kasuga, but she never
imagined she would become that disordered.
In the end, she sought a kiss herself, entwined her tongue, rubbed their
genitals together, and reached climax. Even thinking back on it, it was hard
to believe she had done such things.
Mizuki questioned herself whether it was truly reality or just a lewd dream
she had while sleeping in her bed.
Answering that escapist question was the dull pain resonating from her
lower body.
"It... hurts.."
The pain of having her hymen broken by a penis hot and thick like burning
iron hadn't disappeared even after returning home. Though it wasn't the
intense pain that tore through her body immediately after losing her
virginity, her vagina throbbed, producing intermittent dull aches.
This pain was the clearest proof that what happened earlier wasn't a dream.
Mizuki suddenly crumpled her face and covered it with both hands.
"...I really had s*x..."
She murmured in a voice wet with tears.
She had prepared herself from the moment she decided to go to the hotel
with Kasuga. But just because she was prepared didn't mean she felt
nothing.
While at the hotel, she had been preoccupied with Kasuga and was swept
away by the atmosphere.
But now, back home and alone, she was forced to recognize what had
happened to her.
"...Ugh... Uu..."
A sob naturally escaped from Mizuki's mouth.
The anxiety of not knowing what would happen to her from now on. The
despair that she could never return to the way she was until yesterday. The
surprise of experiencing s*x for the first time. The pain of losing her
virginity. The pleasure of entwining tongues with the opposite s*x. The
guilt of calling someone other than her brother [Onii-chan].
The various emotions she experienced throughout the day mixed chaotically
within Mizuki, causing tears to flow uncontrollably.
For a while, Mizuki continued to cry, stifling her voice so as not to alert her
family.
Even then, the tears didn't stop easily, and exhausted from the s*x with
Kasuga, Mizuki cried herself to sleep.
Mizuki woke up a little past four the next morning.

"――!"
As soon as she woke up, Mizuki reflexively jumped out of bed and checked
the clock.
Confirming that it was not yet past five, she breathed a sigh of relief. If she
overslept and missed her appointment with Kasuga, who knows what would
happen to her—just as she thought that, a sharp pain suddenly shot through
Mizuki's groin.
"It hurts...oh, that's right... yesterday with that person..."
Remembering last night from the pain in her crotch, Mizuki looked down
with a face that seemed ready to cry.
For a while, Mizuki stayed frozen but then she slowly got off the bed and
left the room. She wanted to wash her face with cold water to clear her
head.
Also, there was a pressing reason. If she dawdled, she would be late for her
run with Kasuga.
After getting ready, Mizuki endured the occasional pain resonating from her
lower body and headed to the forest park.
Kasuga, who greeted her at the park entrance, widened his eyes in surprise.
"Mizuki? I told you not to come today, but you came anyway?"
"..Eh?"
"What, don't you remember? I told you on the way home yesterday. You
didn't have to come for the run tomorrow."
Hearing that, Mizuki furrowed her brows. She didn't remember being told
that.
However, looking back, she did recall Kasuga talking to her on the way
back from the hotel. She had been half-dazed from everything that
happened at the hotel, so she barely remembered the conversation, but it
seemed he had told her about cancelling the run then.
Having walked here with much effort, Mizuki sank to her knees in
exhaustion.
Seeing this, Kasuga seemed to understand the situation and walked up to
her, asking, [Are you alright?] as he easily picked her up in a princess carry.
"Waa!?"
While the startled Mizuki flailed, Kasuga moved her to a bench near the
park entrance and sat her down.
Then he spoke apologetically.
"I'm sorry. I should have conveyed it more clearly."
"No, it's my fault for not listening properly, so please don't worry about it."
Still flustered from the princess carry, Mizuki straightened her back and
responded to Kasuga.
Then, speaking quickly without realising it, she asked him,
"If today's run is cancelled, why are you here, Kasuga-senpai!?"
"Well, Mizuki, being a girl, had a hard time with her first experience, but
for a guy like me, it was just pleasurable. I don't need to rest."
Kasuga said nonchalantly and then sat down on the bench himself.
Looking at Mizuki with concern, he continued speaking.
"How are you feeling? If it's too hard to stand, I can carry you home."
"No, you don't have to go that far! I only kneel because I was a bit weak,
but I had no problems walking here."
Mizuki hurriedly responded.
Her statement that she was fine contained a small lie, but the pain wasn't so
bad that she needed to be carried. Understanding this, Kasuga nodded
slightly in relief.
"Alright. But if you start feeling worse, tell me. You're my girl, Mizuki, so
you don't need to hold back."
"Th-that's..."
The moment Mizuki heard the words [my girl], her shoulders trembled.
In the next instant, Kasuga's hand wrapped around Mizuki's shoulder. She
was pulled close, and Kasuga's face filled her vision—
"Mmph!?"
Mizuki's lips were seized by Kasuga.
Instinctively, Mizuki tried to pull away, but with Kasuga's hand around her
shoulder, she couldn't move. Moreover, as he kissed her with soft, sucking
sounds, her body naturally lost strength.
Before she knew it, Mizuki was accepting Kasuga's kiss. Kissing a boy in
an early morning park without concern for being seen was something she
couldn't believe she was doing.
A week ago, this would have been unimaginable. If someone had forcefully
kissed her back then, she would have slapped their cheek and called for
help loudly.
And yet, here she was, not only kissing Kasuga but even intertwining her
tongue with his, and she didn't dislike it. Far from disliking it, every time
she felt Kasuga's rough tongue with her own, a thrilling pleasure ran up her
spine, and a sweet voice escaped her lips.
Confused by her own changes, Mizuki continued kissing Kasuga until he
was satisfied.
—
"――I'm home."
When Mizuki opened the front door after returning from the forest park, her
brother was just coming down from the second floor.
He seemed to have just woken up, blinking sleepily as he greeted her.
"Welcome back, Mizuki. You really put in the effort for your daily runs. I
could never manage that."
"Once you get used to it, it's nothing. Besides, today was more of a walk in
the park than a run."
Saying that, Mizuki slowly took off her shoes, trying to hide her flushed
face from her brother, which still lingered from her farewell kiss with
Kasuga.
"You're going to wash your face, right? Go ahead and use the bathroom
first."
"Oh, thanks. But you can use it first, Mizuki. Standing around like that,
you'll catch a cold."
"I'm fine. As I said, I just took a light walk in the cool park, so I didn't
sweat much."
With that, Mizuki guided her brother to the bathroom and then, still a bit
dazed, entered the kitchen to take out some mineral water from the
refrigerator.
As she gulped down the mineral water from a glass, her brother reappeared
after washing his face.
Seeing Mizuki hydrating, her brother suddenly remarked,
"By the way, Mizuki, you seemed off recently, but you look much better
this morning."
Hearing that, Mizuki furrowed her brow for a split second.
However, before her brother could notice, she smoothed her expression and
spoke to him in a calm voice.
"...You noticed?"
"Well, I am your brother. But even as your brother, I thought it would be
annoying to interfere too much with my teenage sister, so I decided to just
keep an eye on you."
"I see. Thank you for being concerned about me. You don't need to worry
about me anymore."
Mizuki bowed her head to show her gratitude to her brother.
Seeing that, her brother nodded lightly and said,
"You're welcome—now the only remaining issue is with Karen."
Mizuki looked at her brother curiously and asked,
"Did something happen with Karen-san?"
"Well, it's sort of a fight? Something like that."
"It's unusual. You don't usually fight with Karen-san."
Mizuki implicitly asked for more details, and her brother continued with a
troubled expression.
"As you know, Monday is a rest day for the football club, right? So, I asked
Karen out on a date, but she turned me down. It happened last week too, so
it's been two weeks in a row. Last week she turned me down because of
plans with her mother, so I thought for sure she would make time for me
this week, but she turned me down again, this time to have dinner with her
father."
Mizuki nodded as her brother sighed.
"So I said, half-jokingly, that she could prioritise spending time with her
boyfriend this week. But I guess my tone came off as harsh to Karen. She
got upset and said, 『Unless we had plans beforehand, I don't want you
interfering with my family time』. Since then, things have been a bit
tense."
"I see."
Mizuki organised the story in her mind and asked her brother one question.
"Just to confirm, you didn't make specific plans with Karen-san for this
week after she turned you down last week, right? You said you assumed she
would make plans with you, but there was no explicit agreement, correct?"
"Oh, yeah."
Her brother nodded. He hesitated for a moment, recalling how he had
pressured his girlfriend for a breast massage in the manager's room using
the rejection as an excuse, but he didn't mention that, of course.
However, Mizuki, already aware of the breast massage video, sensed what
might have happened from her brother's hesitation.
Given this, there was only one thing Mizuki could say to her brother.
"I can't blame Karen-san for being upset."
"Yeah, I thought so too... Hey Mizuki, could you maybe talk to Karen and
smooth things over for me?"
Her brother put his hands together in a pleading gesture.
Mizuki let out a small sigh.
"...Alright. I'll talk to Karen-san."
"Thanks, I owe you!"
"But I'm just going to talk to her. I can't guarantee she'll be in a better
mood."
"Even so, it's a big help! Thanks, Mizuki!"
With that, her brother headed out of the kitchen with a relieved expression.
As he left, Mizuki added nonchalantly,
"Also, I'll be late coming home today because I have plans with a friend, so
let's handle dinner separately."
In the Kujo household, their parents often came home late and it was
usually up to the siblings to prepare dinner. Mizuki often took on this
responsibility voluntarily.
Her brother responded without much concern,
"Got it. Even though the days are getting longer, be careful on your way
back."
Watching her brother wave and leave the hallway, Mizuki sighed deeply.
Even though her brother asked his sister for help with his girlfriend, he
didn't seem too concerned when she mentioned coming home late. Not that
he was completely indifferent, as he did tell her to be careful.
However, the difference in his concern for Karen was starkly obvious.
Mizuki had always tried to not let it bother her, thinking it couldn't be
helped. But now—
『From now on, I'll protect you in place of your unreliable brother. As your
new brother.』
Remembering Kasuga's words from that night, Mizuki gently touched her
lips.
The sensation of the kiss they shared in the park was still vividly there.
Mizuki clearly felt that her feelings towards her 『Onii-chan』 were
gradually changing.
