"If you're close, you'll get sick and fall ill together."
Other than being teased by those around them, no one suspected their long absence, and Tomoya and Ayane returned to their normal lives safely - three months had already passed.
They are the closest siblings in the school. Their daily lives continue unchanged today.
"Big brother, I brought your lunch."
In a school classroom, the bell rang to signal the start of lunch, and just as the teacher left, a girl with a side ponytail came rushing in.
"Wow, that was quick..."
Tomoya, who was about to put away his textbooks, stopped and called out to Ayane, who was approaching him with a skipping gait.
"Yeah. I can't keep my hungry brother waiting."
"No, but that means classes are over too soon."
Ayane's classroom, which is in a different grade, is on the floor below this one.
Even if I left right after class, there's no way I could get there this fast.
"It's okay. I asked the teacher to deliver something to my brother."
His beloved sister answered with a dazzling smile, and Tomoya lightly held his head and sighed.
Normally, you wouldn't be forgiven for that reason.
It's easy to imagine how he made his request.
"You know, Ayane. I've warned you many times already..."
"It's okay, it's okay ♪ Rather than that... give me a tight hug!!"
As if to interrupt Tomoya's lecture, the girl with the side ponytail hugged him from behind.
Her ample breasts rested on my shoulders and her cheek nuzzled the back of my head.
"Whoa, hey, hey! Know the time and place!"
The feeling of her twin hills bouncing and trembling on her shoulders makes you want to give yourself over and immerse yourself in it.
How much joy does it bring me to have it bounce around like a ball?
The boy had been experiencing this with his whole body since the day their relationship went beyond that of "brother and sister," and just imagining the pleasure of a light touch like this made his body heat up inside.
(But this is no time to be soaking in it!)
Suddenly coming to his senses, he turned around to scold himself.
"What is this?"
Ayane, who had her nose pressed against her brother's head, muttered in a cold, monotonous voice.
The moment I heard it, I felt a chill run down my spine and a sense of intimidation welled up inside me.
Tomoya's heart skipped a beat and he couldn't help but swallow his saliva.
"Um..."
There's no mistaking the tone of this voice.
This is the best proof that her dangerous switch has been turned on.
The light had disappeared from his usually friendly eyes, and they were replaced with a dark, shadowed expression.
(But, why?!)
From just what she was muttering, I couldn't guess what had made her act that way.
In any case, if they act out of control in the classroom, it will be awkward later.
I was racking my brains trying to think of a way to calm him down.
"They're still as close as ever... what a close brother and sister they are."
Before I knew it, my childhood friend had come over to me and was smiling teasingly.
"S-Sayaka..."
"Just like lovers. Ayane-chan is really a spoiled girl."
"...That's right, Aya is a spoiled brat, so she's always clinging to her big brother."
Sayaka slumped her shoulders in exasperation, and Ayane responded in a normal voice.
It seems he came to his senses at the last moment.
Breathing a sigh of relief, Tomoya thanked his childhood friend with a wink for his thoughtfulness in speaking to him at just the right time.
"Really, I never get bored of this everyday life. It's not easy to keep up with the camouflage."
The girl with twin tails crouched next to Tomoya and smiled mischievously.
"Really, thank you for everything."
From brother and sister to lovers, and then to husband and wife, the two have changed their relationship, but there's no need to openly declare it and invite unnecessary trouble.
After discussing it, they decided to hide the situation from the school.
However, that did not mean that Ayane held back on her actions at all.
Like now, he is being unreserved and clingy, clearly acting like a lover.
Sayaka sometimes makes fun of it like this, turns it into a laugh, and tries to cover it up.
(Well, I guess it's okay if you don't do that though.)
With a wry smile in my mind, I looked over at my classmates.
"Really, Nakata's brother and sister are a lovey-dovey couple, or what can I say..."
"It's too late now, isn't it?"
"That's right, it feels like a scene from everyday life."
The students watching from a distance all just laughed lightly.
This closeness between the two of them has been going on since before their relationship changed, and it seems to have become a normal thing for the Nakata siblings.
Even when he was seen hugging her or kissing her on the cheek as a greeting, he would just be surprised and say, "Here we go again," and no one would suspect anything.
(That in itself seems a bit complicated though... haha)
The gazes of my classmates are becoming more lukewarm with each passing day.
Also, recently, some of the girls have started to blatantly look away from me, exuding an aura of rejection as if they don't want to get involved with me.
Many of these are kids I've been friends with and have had casual conversations with for a while, so I feel a little lonely.
"What are you so depressed about, Tomoya? Get yourself together already."
As he was thinking about this, his childhood friend suddenly clung to the boy's arm.
Her breasts were just the right size and beautifully shaped, and though they were smaller than Ayane's, the soft feel was so pleasant that Tomoya's cheeks involuntarily turned red.
(Well, that's bad!)
If I reacted, it would be a disaster. By the time I realized that, it was too late.
"Sa-chan... what are you doing? To Aya's big brother?"
Just when I thought Ayane's mood had improved, her voice had returned to its cold, emotionless tone.
She awkwardly turned around and, sure enough, the highlights in her eyes had disappeared and she was glaring at Sayaka with a dark expression.
"Isn't it okay? I'm just spoiling my childhood friend."
"I'm telling you this because it's not good! Big Brother belongs to Aya!"
"If you restrict me too much, I'll end up hating you."
With a flustered Tomoya in between, the beloved younger sister and her childhood friend continue to argue at a brisk pace. Such lovers' quarrels are a common sight these days, and the students in the classroom don't make a big fuss.
"Ugh, just give up already! You idiot Sa-chan."
"Don't worry, I won't take it by force unless you do something reckless like last time and Tomoya dislikes you again. But if that does happen...hehe."
"I, I won't. Aya, I'll never do that again...ugh..."
As Sayaka tingles Ayane, her cold expression suddenly fades.
Recently, her childhood friend with twin tails has become very good at treating Ayane.
She thought that their relationship might fall apart when Tomoya chose his beloved sister, but it turned out that her worries were unnecessary, as they had built a strong friendship between them since childhood.
"Ugh, that's enough! Big brother, let's go eat quickly. Sa-chan, don't come with us today!! We'll be eating just the two of us."
"I know. Tomoya, just try not to do anything weird at school."
"What are you talking about... Ah, well, whatever."
Tomoya gave a wry smile as his childhood friend finally let go of his arms, and was urged by Ayane to stand up from his seat.
"Where should we go? The weather is nice, so we could go to the school grounds, or maybe the cafeteria..."
"...Leave it to Aya. Here, this way."
Saying this, the girl with the side tail grabbed her brother's sleeve and started walking.
"Ah, oh, hey, don't pull me. Where are you going...hey."
Although feeling uneasy about the slightly more forceful guidance than usual, Tomoya followed them.
Led by my beloved sister, we arrived at the top of the stairs at the very end of the school building.
It was a landing that led to the roof, which students were not allowed to enter.
"Are you going to eat here?"
It was lunchtime and the school was so quiet it was hard to believe it was a bustling place.
It certainly seems to be a hidden gem, but it's a bit too bleak a place to have a meal.
I tilted my head in confusion - and then...
Suddenly, I was pushed onto my back and pushed against the wall.
"Whoa, hey, Ayane!"
He turned around in a panic and protested to his beloved sister, the culprit.
But without replying, she suddenly jumped into my chest.
"I'm sorry, Onii-chan. I tried to hold back, but... I can't!"
Ayane apologizes in a high-pitched voice, stretching her back and pressing her nose against her brother's neck.
Sniffing like a dog.
Tomoya, who was overwhelmed by his sister, could no longer bear the tickling sensation of her breath blowing on his sensitive collarbone and began to wriggle.
"Stop it, Ayane. Why did you smell..."
"Yes... it's a nasty smell. Something unnecessary has been mixed into my precious big brother's scent..."
Ayane muttered this, her eyes once again turning vacant and cold.
He remembered what had happened earlier when she'd hugged him in the classroom. He'd thought he'd managed to fool Sayaka thanks to her words, but it seemed he'd been wrong.
"I hate the smell of a woman other than Aya coming from my brother's body."
"You can't smell it, can you? I can't tell!"
I sniffed desperately, but nothing came out except the refreshing scent of citrus fruits wafting from my beloved sister's hair.
"Sayaka clung to me earlier, so is that why...?"
"I can tolerate Sa-chan's smell. But other women's... I can't tolerate it."
Ayane's voice was becoming increasingly irritated and monotonous, and she stopped moving, her nose pressed firmly against her brother's neck.
I felt like I was standing nearby watching a dynamite fuse being lit.
Tomoya tried to contain the shiver that went down his spine and desperately tried to think about what was going on.
And then... something suddenly occurred to me.
"Today during gym class we had co-ed dance practice... is that it?"
"Yeah. Aya was watching you dance from the window too."
With her face buried in his neck, Ayane nodded slightly in response.
As an older brother, he should scold her and tell her to concentrate on her lessons, but he couldn't provoke her by saying that now.
"Well, it can't be helped. It was class after all..."
"Yeah, it would have been normal to just hold hands and dance... but... that wasn't the case, was it?"
My beloved little sister raised her eyes and glared at me questioningly.
Tomoya was so impressed that he almost stepped back, but the wall blocked his escape route.
I tried to calm him down with an awkward smile and thought back to what had happened in class.
"Um... Ah, there was one kid who playfully hugged me."
I remember one female student hugging me tightly and asking me to dance something like ballroom dancing, even though we were supposed to be dancing a folk dance where we held hands.
The teacher immediately warned me, and it only lasted a few seconds, but I wonder if that much contact is enough to make the smell stick so badly that it can't be removed.
(Only Ayane would know, absolutely!)
The younger sister is as spoiled as a puppy, and when her older brother is around, her sense of smell becomes like a dog's. Realizing this once again, he watches Ayane, who remains motionless, glaring at him without even moving a brow.
"It's not your brother's fault… Yes, Aya knows that. But he's not being very self-aware… After all, your brother is your husband."
"I, I know. I'm Aya's lover and her husband. But, that was just a prank..."
"...Big brother, you're so insensitive. You don't realize how popular you are. It's not just that girl from today, there are many other evil sows out there who are plotting to mess with you... It's going to be really hard to have a proper discussion and get them to understand."
"discussion?"
"That's right... I'll tell him not to do something so cruel as to lay a hand on Aya's precious big brother... I'll talk to him until he fully understands."
The little sister with the side tail smiled meaningfully, the corners of her lips slightly raised.
What exactly was this "discussion" about? Tomoya realized that if he pursued it further, he would end up with a pit in his stomach, so he decided to just give a weak smile and dodge the question.
(Or rather, the girls in my class...)
I can think of several people who I used to be close to, but who have recently started blatantly avoiding me.
Perhaps they are the people Ayane is talking about "discussing" with.
No one has ever confessed their feelings to me, but I have been invited to go out with someone and asked several times if I had a crush on anyone.
"Ayane, I told you before not to do anything that would cause trouble or worry to everyone..."
As expected, I couldn't just ignore it and tried to warn him - but
"You're the one, Onii-chan... hmm, haa... don't make Aya jealous anymore."
In return, my beloved little sister protested and suddenly pressed her lips against my brother's neck.
He lightly raises his front teeth and bites gently, leaving many red teeth marks.
"Hmmm, aah! Hey, don't leave marks in places like that! If someone sees me... Ahh, hmmm, haa..."
She was sure that people around her would suspect something, so she tried to stop, but she couldn't bear the ticklish sensation and ended up raising her voice.
"I know, but I can't help it... smooch, haa, get rid of the smell... nfu, I'll have to rub Aya's scent all over you instead... smooch, lick, haa, mmm!"
Ignoring Tomoya's warning, my beloved sister not only bit him, but also pressed her lips firmly against his penis and began to suck hard. At the same time, she stuck out her tongue and smeared her hot, slimy saliva over his penis.
"Hey, hey! You even made a love bite, that's....ah, ugh."
Around her neck, collarbone, and even her chin, bloodshot blue bruises were carved into her skin, mirroring the shape of Ayane's small lips.
At first, the sensation was merely tingly and ticklish, but before I knew it, it had turned into a frustrating pleasure that sent shivers down my spine.
"Ayane, stop. No more than that..."
"Oh no, the smell hasn't gone away yet, and Aya's scent hasn't permeated it yet. And... kiss, hmm... Big Brother's voice is starting to sound pleasurable♪"
"I told you, stop! If you do this to me....ahh, aaahhh"
Tomoya desperately tries to stop Ayane, but his beloved sister is completely turned on and has a look of ecstasy on her face as she relentlessly presses her lips against his.
The sound of a loud, almost deliberate kiss echoed across the landing, and not satisfied with just my neck, he stood on his tiptoes and pressed his lips down to my cheek.
"You're worrying too much about smells. This...ugh!"
The voice that spoke was made to sound high-pitched by the sweet scent that wafted from Ayane's long side tail, which swayed gently with her movements.
I guess because I was constantly told about the smell, I naturally became conscious of it.
Not only could he smell her hair, but also her sweaty forehead and the saliva that had been applied to her, each of which emanated a subtly different sweet scent that was oddly distinct.
"Shuh, mhh, haa, Onii-chan... that's good, feel Aya's scent more. Come on, here... let's get your dick hard too, okay? I'll be mad if you don't get an erection."
Ayane whispered in a nasal, sad voice, slowly sliding her right hand, which she had placed on the boy's chest, down, teasing him.
He wraps his palms around his solar plexus, then his stomach, and then his crotch through his pants, stroking it all over.
"Fah, ah, hmm... That's not good. This is school. You promised not to cause worry or trouble to those around you... haa haa, uuh!"
The warmth of his palms is clearly felt even through the fabric of his pants, which are by no means thin.
This slowly spreads to the already throbbing penis, making it more sensitive.
I took several deep breaths to try and calm myself down, but it was no use.
Blood flowed into the corpus cavernosum in time with my heartbeat, and I gradually began to feel more short of breath.
"I know. That's why I looked for a place where no one would come here... Hmm, ha, so that I can get along with Onii-chan and the rest of the school♪"
"No, that's not the problem... Ah!"
"You found it well," Ayane said with a proud smile, but the voice he was about to make a remark to her was cut off by the stimulation of her lightly grasping his erection through his pants.
He grabbed the bulge that was clearly visible in his pants and started moving it back and forth.
"Kiss, lick, haa, I'm so happy... haa, mhmm, just the kiss and Aya's scent is making my dick hard. I can really feel Onii-chan's love."
"Th-There's nothing I can do if you do this to me!"
Every time my beloved sister's palm slid up and down, my erect rod, held down by my pants and underwear, trembled.
A painful ache reverberated all the way down to my waist, and my breathing became rough, like after running at full speed.
"I'm sorry, Onii-chan. Aya, I'm always jealous... nfu, haa, I'm such a naughty little sister who always wants to be spoiled by you... as your wife. But, kiss, I can't help it."
Ayane finally let go of the lips she had been pressing against his, and looked up at her brother, panting hotly, with her eyes narrowed in sadness.
Meanwhile, his right hand continued to move, gripping and rubbing the main rod.
When the underside of the penis is stroked while being pressed firmly with the base of the palm, the pulsation becomes more intense.
"Even I... I can't take it anymore."
Unable to resist the pleasure that nearly gave way to his loins, Tomoya finally put his arms around his beloved sister's shoulders as she smiled seductively at him, and embraced her tightly.
My body was hot, and the sweet scent in the air was getting stronger.
With every breath, his heart was filled with thoughts of his beloved sister, and the call of reason to know his place faded away.
"Let's do it, Onii-chan. Until Aya's scent has permeated her... Until Aya has your scent permeated her. Do it lots so that you won't be jealous anymore."
Ayane licks her lips, wet with saliva, with her tongue and invites you with a whisper.
Driven by the urge welling up from deep within his chest, Tomoya changed positions with his sister in his arms and pressed her slender body against the wall.
He removes his hand, unzips his pants with his right hand and takes out his stiff penis.
At the same time, he grabbed Ayane's right thigh, which she had slightly raised, with his left hand, and as soon as he spread her legs wide, he slipped his body between them.
A thin, bushy honey garden is visible from under her rolled-up skirt. Before she even realizes it, Ayane has skillfully pushed her shorts aside, revealing her ripped, wet slit.
A clear drop fell to the floor with a plop. The folds of her labia minora, which were swaying wildly as if being blown by a strong wind, were already covered in a large amount of love nectar.
Wanting to feel that heat as soon as possible, Tomoya grasped the base of his own rod and guided the tip there, savoring the maddening feeling that was swelling within him.
Squelchy... The obscene sound of water echoed around the area, and a burning heat was transmitted to the head of his penis, which had become sensitive from rubbing against the lining of his underwear for so long.
Ayane must have been waiting for this moment too, as the moment we made contact, her aphrodisiac mucous membrane began to squirm and she began to suck on the tip of my penis.
When the large, undulating labia meat is guided to the opening, it clings to the tip and opens and closes violently, as if begging to be penetrated quickly.
The ticklish yet pleasant sensation made Tomoya groan involuntarily.
"Ahh... Ayane, your pussy is so wet. Why is it so wet?"
"But... hmmm, haa, when I saw you dancing with another girl, I got jealous... I wanted to cling to you, I wanted to dance with you... haa haa, I can't take it anymore! Come on, let's do a sexy dance with you ♪"
Ayane begs in a sweet, nasal voice, then bends her knees and lowers her body.
At almost the same time, Tomoya thrust his hips forward, and the stiff cock that had been placed against her vaginal opening buried itself into her flesh with more intensity than either of them had imagined.
Slosh, squelch, squish, squish, squish!
"Hyaah, kuh, mmm! Ah, k-, here it comes... Big brother's cock, Aya's only cock, suddenly deep... kn, ahhh!!"
Ayane leans her weight against the wall, her cheeks flushed red as she moans in agony.
The vaginal walls tremble violently, and the nectar that had accumulated in the gaps between the wrinkles drips out in abundance as they wrap around the meat rod, welcoming it.
Driven by the undulating mucous membrane, I reached the deepest end, and as if it had been waiting for this, the cervix descended and devoured the glans.
The pre-cum that had slightly wet the tip of her penis was sucked up in an instant, and then it tightened as if to say that it wasn't enough.
It's only been a short breath since he inserted it, but it already feels so good that it makes me want to give way and spill the hot fluid that's building up inside me.
"That's sudden and intense. Inside... it's hotter than usual."
"Yeah, because doing it in the middle of the school makes my heart pound! No... ngh, my body is so hot I can't stand it anymore!! Come, suddenly pound Aya's uterus hard."
With a joyful voice, Ayane opens her uniform and shirt.
All the buttons are undone and the ribbon around the neck is also untied.
Her bra was also pulled down, and her breasts spilled out, bouncing wildly.
Her white, milky skin was damp with sweat, giving off a sweet and sour smell. Just as she said, the thrill of this situation was making her body heat up from the inside out.
Beautiful, bowl-shaped breasts with the pointy flesh in the center pointing slightly upwards.
No matter how many times he looked at the alluring bulge, his eyes were drawn to it, and Tomoya's erection grew stronger, pushing back against the tight walls of her flesh.
"Hehe, I'm so happy that Aya's breasts always make my dick hard. It feels so good... look at them and touch them lots ♪ Make your dick even harder!"
"It's grown big enough now. It's getting hard to breathe inside... Ugh, haa haa, it's moving. Like this... I can't stay still!"
My beloved little sister bends her back and shakes her chest to accentuate it, seducing me.
Aroused by the erotic sight, Tomoya begins to shake his hips frantically.
Slurp, squish, squish, squish!!
"Ahh, it feels good! The smell of cock is being rubbed into my pussy! I love it, I love this feeling!! It feels so good to be fucked hard by my big brother's big cock ♪"
The sticky, melting flesh and shaft rub against each other hotly in time with the rhythmic movements of her hips.
Even though they have been making love countless times over the past few months without a single day in between, their flesh passage still retains the same exquisite tightness as it did the first time.
As she pushed back and forth, forcing her body to part the tight, constricted space, Ayane's moans grew louder and louder, along with the seductive sound of water.
Since the landing is a place where noise tends to echo, it seems likely that the noise would be heard all the way to the floor below.
"Ayane, please, lower your voice a bit. If they notice..."
"Ah, ha ha, I can't do that... The walls of my pussy are being rubbed against it and it feels so good... I can't stop ♪ Eheh, ha, ahh"
"I can't say that! Ugh..."
Although he couldn't shake off his anxiety, Tomoya couldn't stop his thrusts, which felt like a thin layer of skin was peeling back with each stroke, exposing her pleasure nerves.
With each thrust, her vagina narrows and sucks the entire shaft, causing a sweet throbbing sensation that feels like it could break your waist.
Even though he knew he had to stop until Ayane's voice quieted, he couldn't stop thrusting forcefully, pressing her slender body against the wall.
"Hahi, mmm! Ahh, that feels good!! It's intense, when you do it so much, it really makes me feel that Onii-chan loves me. I'm so happy, I'm going to make more noise."
"No good... I'm letting out too much. Ugh... ugh."
While trying to calm his sister who was writhing in agony, he used the nectar that was leaking out of her as a lubricant and his thrusts accelerated. His head went numb and he was about to give up and say, "Whatever happens, happens."
I could hear soft footsteps coming up the stairs from below.
"Ugh, this is bad, Ayane! S-Silence..."
It would be no joke if someone saw me like this.
The older brother, driven by a sense of crisis, pleaded with a pale face, but his beloved younger sister, gasping and writhing in agony, could only relax her cheeks in delight with a faraway look in her eyes.
"Okay, I'll show it! I'm going to show everyone in the school how much love Aya and Onii-chan have for each other. Hafu, hmm, haa, ahaha♪"
"Wh, what are you saying, Ayane? That's..."
"Will everyone be surprised? Or shocked? But... ha, ha, if they see, they'll immediately know that Aya and I are lovers... No more sows trying to get their hands on Onii-chan, and all those annoying garbage bugs trying to hit on Aya will disappear too."
It seems that something had been flipped in Ayane's mind, as she continues speaking without listening to Tomoya's plea.
She must be fantasizing about what would happen if it really happened, and she's getting excited. The shivers down her spine are getting stronger, and the undulations of her vaginal walls wrapping around his cock are getting stronger.
"Ugh, wait a moment. That's not possible..."
His penis is squeezed so hard that it feels as if it is being crushed, and Tomoya's face contorts in response to the intense stimulation.
Once Ayane has reached this point, half-hearted words won't reach her.
However, it's been three months since they were united, so they have learned how to deal with it.
"I don't want to let other people see Ayane's naughty side."
"Huh... hmm, big brother?"
"Ayane is my wife, so I'm the only one who can show her embarrassing poses. I'll never let anyone else see her. I'll have her all to myself!"
He speaks his true feelings, which are not lies, in a slightly forceful tone.
Then the light returned to Ayane's eyes, and her gaze began to wander, as if she was a little embarrassed.
"I, I see. Yeah, that's true... Aya doesn't like being seen by anyone other than her big brother either."
"Isn't that right? So please...hold your voice."
He gently spoke to his beloved sister who answered in a low voice, and for the time being he let out a sigh of relief.
He loves Ayane too, and is just as obsessed with her.
When I confront her directly about these feelings, her jealousy disappears and she often feels relieved, returning to her senses.
(But it's true. Ayane's face is so cute... I don't want to show it to anyone.)
Her face was flushed and melting with ecstasy, exuding a different charm from her usual innocent cuteness. It was something no one knew about except her, not even her parents.
Just thinking about someone else seeing this makes my heart flutter and an uncontrollable urge wells up inside me.
(But... I guess I'm just as jealous as Ayane. Ahahaha...)
"big brother...?"
As my thoughts started to get out of control, I chuckled wryly, when Ayane, who had been watching, tilted her head curiously and asked me a question.
"Hmm... It's okay, but more importantly, is it okay to move? Can you hold back your voice?"
The boy regained his composure and once again asked his out-of-breath sister.
The vaginal jar was still tight, but the uterus had descended further than before, and the glans felt more deeply buried.
The footsteps that had been approaching earlier seemed to have receded, but there was no telling who might come up again. It would be dangerous to continue panting too loudly.
"Haa haa, if you do it too hard it might feel too good... but I can't hold back. If you don't do it lots and lots, my uterus will hurt so much I think I'll go crazy."
The little sister with the side tail pleaded with me with tears in her eyes.
Hearing this, Tomoya also seems unable to contain the excitement that makes his loins numb.
How can I fully enjoy this pleasure without making any noise?
Tomoya was gazing at Ayane's slightly wet, cherry-colored lips as he thought about it...and half-unconsciously he brought his lips close to them.
"Hmm, haa... Big brother... mmm... ♪ Kiss, mmm, mmm!"
When their lips pressed together tightly, Ayane let out a muffled voice, sounding a little surprised.
After stiffening for a moment, my beloved sister narrowed her eyes with joy and inserted her tongue.
"Puha, ha, Ayane... ngh, if I cover my mouth like this, my voice won't echo."
Tomoya nodded slightly, thinking it was a good idea, and then he took the initiative to stick out his tongue and entwine it with hers, moving it back and forth slowly so as not to make too much of a splashing sound.
"Yes, this feels good... slurp, slurp, ahaha. Suck it... Aya's tongue, more and more... slurp, slurp, mmm!"
"Yes. Slurp, slurp, mmm, haa haa."
Tomoya put his free right hand around Aimi's neck, pulled her face towards him, and began to suck her tongue harder than before.
They make love on campus. Perhaps because they are excited by this immoral situation, the saliva that seeps onto their tongues tastes sweeter than usual, almost like starch syrup.
"Puh, hah... kiss, Ayane... you're so sweet. Lips and tongue... everything."
"Yeah, Onii-chan's is sweet too... haha, it makes me feel all fuzzy deep in my stomach, please... Onii-chan's saliva seems to act as an aphrodisiac to Aya."
Ayane, with her tongue entwined with his, leaving a string of seductive saliva, whispers in a dreamy voice.
Just as he said, her flesh pot was getting hot as if it was on fire.
The trembling of the mucous membrane walls becomes more active, and the meat spear that is being sucked nonstop is about to melt.
I want to stir things up like crazy and rise to the top together.
Such crazy impulses make my head boil, and it's hard to stay sane.
"Big brother, please... give me lots of kisses and cock! Aya, I'll try my best to hold back my voice... naughty kisses with Big Brother and hold back."
"Yes. Don't let go of my lips. Keep going like this... kiss, haa, uuuh."
As soon as he declared this, Tomoya pressed his lips against his beloved sister's once again.
It was as if their noses were about to collide. As they rubbed the surfaces of their tongues together, they entangled each other violently, and their hip movements, which had been held back, began to accelerate roughly.
Slurp, squelch, squelch, squelch!
"Mmmm, mmm, hah, mmm, mmmm!?"
Ayane's wordless moans escape from the gap between their devouring lips.
If it hadn't been blocked off, it would have reverberated quite loudly throughout the landing.
Her narrowing vagina is forced open, and her uterus is thrust at short intervals. Tomoya shakes her hips frantically, suppressing the moans that are filled with the insane pleasure.
"Smooth, haa, mmm, Ayane... mmm, kiss, haa haa"
"Ahhh, ahhh... mmm, hah, haa, oniihyaa... mmm."
The melted vaginal mucosa and the rough, hard shaft with its veins bulging out rub against each other without rest.
Perhaps the increasing pleasure was causing her legs to relax, as Ayane's hips began to drop little by little. His thrusts naturally became deeper, until it seemed as though his entire head was buried inside her uterus.
"Haha, the kiss between your dick and uterus... sigh, ha, it's getting intense."
"Yes, I love it... Aya, I love kissing you, big brother... Suck, kiss, lips and uterus... I love everything, everything... Ah, do it, more, more."
When I parted my lips to catch my breath, Ayane, with a dreamy look on her face, pleaded with me in a sweet voice.
She seductively wiped her wet lips with the tip of her tongue, then wrapped her arms around her brother's neck and clung to him.
"Hmm, kiss... thrust more... kiss me more! Not just on the lips, kiss me here and there... hahe, mm, lick me."
"Haa haa, no, I'm just doing it to keep my voice down... hmmm, can't be helped."
Tomoya nodded with a wry smile at his beloved sister's request, who was simply enjoying the kiss.
Her cheeks were bright red and looked soft, and a few strands of brown hair clung to her forehead, giving her a seductive look.
I want to cherish such places that exude an indescribable sexiness.
Driven by his rising emotions, Tomoya moved closer to her, his lips wet with saliva.
"So hard that it leaves a mark... kiss, mhmm, kiss."
Remembering what Ayane had done for me earlier, I gently bite and suck on her plump, healthy cheek. The warmth there is different from lips, and it's so comfortable I want to keep touching it forever.
After repeating this several times, he slowly slid his lips down to her forehead, raining kisses down on it in rapid succession.
My beloved sister's face, which had been flushed pink with cherry blossoms, was now covered in darker red marks.
"Ahaha, that's good. Lots of kisses... I'm happy to have the proof of being your wife ♪ Next, kiss here, lots of kisses here too... kiss the depths of my pussy too! Poke the tip of your dick hard into my cervix and give me a semen kiss. Give Aya's eggs lots of fertilization kisses!"
Perhaps her reason had completely melted away from the countless kisses, as Ayane's eyes turned moist with ecstasy and she pleaded with him, twisting her spine in a frenzy.
The arms around Tomoya's neck tighten, and he cries out in agony as he generously presses his spilling breasts against his stomach.
"Hmm... That's why I said your voice was loud. Kiss, hmm... ha ha."
While trying to calm his beloved sister down as she blurted out obscene words that would be inexcusable if someone heard them, Tomoya pressed his lips against his again and began to move his hips.
With each thrust, his strength and desire grew stronger, penetrating straight into the vaginal jar where each fold of flesh was actively wriggling and entangling itself. With each stroke, as if to lift her uterus, the vibrations caused her breasts to sway, and her sweaty breasts gently caressed her stomach.
"Big bro... nfu, I love you, Aya... I love you so much, kisses, haa haa, I love you so much I can't control myself and don't care about the time or place!"
"Even I... kiss, haa, even if I warn you, you always end up letting it go in the end. Ngh... that's how much I love you. I've always loved you, Aya... kiss, haa haa!"
They once again convey their love for each other with their lips and tongues, and begin to shake their languid hips.
I could also hear faint voices coming from downstairs, but I no longer had the time to stop moving and pay any attention to them.
Keeping their lips tightly pressed together so as not to scream out loud, he simply stirred her wet vaginal passage vigorously as she approached the imminent climax.
"Ahhh, mmm, slurp, haa, mmm! Onii... ahh, I'm, I'm coming, Aya... no more, please... I'm, I'm coming, ahhh"
My beloved sister, who I was holding tight to, let out a husky, sweet voice with a sloppy, relaxed expression. It seemed she had reached her peak before me, as her heated body relaxed and her knees gave way.
Tomoya thrust his hips forward as if to finish him off, causing his penis to go even deeper. With a loud squishing sound of flesh being pushed aside, the head of his penis pierced her cervix, which had been torn open by repeated thrusts.
As if that spot had acted as a switch, the entire vagina contracted tightly, and Tomoya could no longer stop the heat that had been building up at his base from running up his urethra.
"It's coming... mmm, smooch, mmmm!"
He quickly entangles his tongue with hers again, and releases his lust as he lets out a moan that wells up from the bottom of his stomach into Ayane's mouth.
Splat, splash, splat, splash, splash!
"Hii... hiiii! Ah, it came out... Big brother's semen is kissing Aya's egg a lot, it's coming into my uterus, kuuuu♪"
A thick, milky liquid, boiled over by the heat of pleasure, spurts out with the force of an eruption.
The liquid spurts out from the tip of the glans that has entered the cervix and hits the wall directly at the back.
Each time, the aphrodisiac mucous membrane melted in orgasm and spasmed violently, and the shaft was handled with heat. The final stimulation sent a strong tingling sensation all the way to the scrotum, and the intense orgasmic sensation never subsided.
"Ayane, I'm still coming... ugh!"
"Hiii, hiii, I'm coming... Aya, I'm coming more! Mm, uuh!!"
My beloved sister, whose spine was convulsing in time with the ejaculation, pressed her lips against mine again as if to say she could not hold back any longer. The moment her vaginal opening contracted as if biting the base of my rod, clear droplets oozed out from just above it, making a whoosh sound.
(No, it's pee... I think it's squirting.)
Sweet-smelling sex fluid forms a small puddle on the floor.
Tomoya watches with narrowed eyes as the spurt continues for as long as his own ejaculation.
"Haha, ha, mi, stop looking... Aya, it's embarrassing."
"Isn't it okay? I'm Aya's husband after all."
Ayane pleaded with him, embarrassed and half crying, and Tomoya smiled back mischievously.
I was once again overwhelmed with happiness at having such a cute little sister all to myself.
"Mmm, you're so naughty, Onii-chan. But... I love that about you too."
When Ayane finally finished squirting, she buried her face in her brother's neck to hide her embarrassed red face. She pressed her lips against his neck again, sucking so hard it hurt a little.
"Hmm... Hey, Ayane. That's a bit too much."
Tomoya frowned and tried to stop him, but he didn't let go, and when he finally did after a full minute or so, that spot was bright red.
"The mark I made earlier was a little faint. If it's this dark, it'll definitely last through the day. Hehe, it'll mark me as Aya's...♪"
With a smile on her face, my beloved sister traced the kiss mark she had carved herself with her index finger and nodded in satisfaction.
There was no way he could say it was just an insect bite, so Tomoya could only give a wry smile.
(Sayaka will probably say something about this again...)
I was a little scared to imagine my classmates' reactions, but... I'd managed to get away with it up until now, so I'm sure I'd be able to manage. I told myself this, and somehow managed to suppress the urge to skip my afternoon classes and run away.
If I were to say I was going home, my spoiled little sister would surely come along... and if that happened, I'm sure we'd be passionately confirming our love for each other until tomorrow morning.
(That would be nice, but I spent the whole weekend holed up at home... I really should control myself a bit. Yeah, I'll have to be patient today!)
"...Big brother is still fine. He's still trembling inside Aya."
"Ugh! N-no, just a bit... ahahaha."
I couldn't help but imagine that, and my shaft reacted.
I somehow managed to cover it up with a dry smile so that Ayane wouldn't notice.
Did it go well, or was he just pretending not to notice, understanding her beloved brother's feelings? Ayane didn't say anything more, but simply buried her face in his neck, looking happy.
"Aya... I'm so happy. The person I love most in the world has been by my side ever since we were little. We'll always be together from now on... I'll do something about anyone who gets in my way ♪ Don't worry about anything, just leave it to me."
"Yeah. But... let's keep it as peaceful as possible."
Is this a joke or is it serious?
Tomoya sighed in exasperation as his beloved sister smiled with her lips twisted meaningfully.
She's cuter than anyone else, loyal...and a little scary.
Only I can hold the reins of my beloved girl, who is both my sister and my lover.
"Hmm...there's still a nasty smell here. The other sow...ah...she's persistent. She must have evil intentions towards Onii-chan...what should I do? Ugh"
"I-I told you not to say such scary things! Haha... haaa..."
My beloved little sister rubbed her nose against the nape of my neck, and her eyes once again became dark and the light had gone out.
There will probably be troubles from now on, but their love for each other remains the same.
So I'm sure we can overcome this and find happiness together.
Tomoya gave a wry smile as he felt cold sweat running down his back again.
