"You two... what are you doing?"
The next morning, it was a gloomy weekday for the students.
A quiet back street leading to the school, not far from the siblings' house.
Tomoya and Ayane were in the middle of bringing their faces close together as if they were going to kiss when Hoshi Sayaka, a gentle girl with wavy, medium-long hair that was almost blonde and tied in twin tails under her ears, called out to them.
"Hmmm...huh?"
Tomoya turned around with a puzzled look on his face, and in his mouth was a slice of apple.
"Tch... Good morning, Sa-chan."
Ayane, who had just nibble on half of it, turns around with a slightly displeased look on her face.
Unlike inside the house, a simple black headband adorns her head.
Her fashion sense is enhanced by frequently changing her hair accessories to match her outfit.
"Not good morning... what are you doing?!"
"Well, Ayane said she wanted to leave the house earlier than usual today, so I didn't have time to leisurely enjoy this dessert."
Tomoya has known Sayaka since her family moved in next door when he was in kindergarten, and he is well aware of her earnest personality.
I had a premonition that I would be scolded for misbehaving, so I answered apologetically.
"I understand that, but that's not it! Why now, Ayane-chan..."
"Well, because you asked for half. What's the problem?"
"How you divide it is the problem!"
Sayaka, her cheeks flushed the same color as the apple skin Tomoya was currently holding in his mouth, pointed to the part Ayane had nibbled off and complained.
"Sa-chan is so noisy in the morning. I know it's bad manners, but isn't it unsanitary to hold it in your hands and break it?"
"But still, isn't it embarrassing, like feeding someone by mouth?"
"Not at all, we're brother and sister, right?"
"Hmm... well, I guess I'd be a bit worried if someone was watching."
The twin-tailed girl looked at each other with a dumbfounded expression, and the siblings tilted their heads in confusion, wondering why she was overreacting so much.
"Now, let's go, big brother. Aya, we're going to be late."
"Yeah, that's right. By the way, what do you need to do to leave early? You don't have any club activities or committees to attend to, do you?"
"Oh, wait a moment, I'll go with you. Tomoya... lend me your hand!"
Without answering her brother's question, Ayane clings tightly to his right arm and starts walking.
Sayaka, who was in danger of being left behind, hurriedly chased after him and tightly grasped Tomoya's left hand as if to say that she would not let him get away.
"What's going on, even Sayaka? It's hard to walk..."
"That's right. Sa-chan, could you please refrain from coming? ...I went out of my way to come out early, but now it's all gone."
"I didn't come to pick you up this morning... I guess that's what happened. You really can't let your guard down or leave any gaps."
The girls were flanking the confused-looking boy, whispering and exchanging glances.
Perhaps because he had crammed his meal in a hurry, Tomoya felt a slight ache in his stomach, but he grimaced and swallowed the apple that was left in his mouth.
(You've been asking a lot of questions about Ayane and me lately.)
Although they are the same age, she has always had a reliable, "big sister"-like quality and has often given him warnings, but recently, since she is now his younger sister, he has been giving her more detailed advice.
(Ayane asked to be fed, so I fed her her lunch, but she told me I was spoiling her too much. And... the other day, she was shocked when she saw me carrying Ayane on my back.)
She jumped onto my back jokingly saying "I'm tired" so I just left it there thinking it would be okay once in a while, but perhaps it was something that she couldn't ignore as she had the personality of a class representative.
"Aren't you embarrassed, Tomoya? Being so close to me."
"Hmm, no, nothing special. It's been a common occurrence since long ago."
With a crease in his brow, his childhood friend scolded him, saying, "What!", but he was vague in his words.
She's a spoiled little sister who even gets into the bath and bed.
Now, I don't feel embarrassed about being hugged.
...However, I'd be lying if I said that the soft, trembling feeling of her jelly-like material pinching my upper arms didn't bother me.
(Ayane, you've been getting bigger and bigger lately.)
His arms are buried in the paws, which have grown so large that they are difficult to grasp with his hands.
The feeling of being rubbed against that trembling area is so pleasant that it takes your breath away.
Knowing not to think too much about it, I quickly turned my gaze towards the clear blue sky and took a breather.
"They're brother and sister, so it's fine, right? Sa-chan, if a grown-up boy and girl were to walk around holding hands, it would start some weird rumors."
"I don't really care about rumors. As long as I'm with Tomoya... it's fine!"
While Tomoya was trying to gather his senses, the beautiful girls on either side of him had suddenly leaned forward and were glaring at each other.
Ayane, who had been in a good mood when they shared the apple, now looked expressionless with no readable emotion, while Sayaka puffed out her cheeks and looked obviously unhappy.
(They get along well... as always)
Perhaps they were just fighting buddies, as the boy who was closest to them had seen them bickering over petty things on many occasions since they were little.
That doesn't mean they genuinely dislike each other. In fact, Sayaka is the only person Ayane shows such strong feelings towards, other than her brother, and they often go out together just the two of them.
There is no need to be reserved; they have a comfortable relationship, like real sisters.
(But still... you two are too close.)
As usual, Ayane's melon-sized breasts were pressed firmly against my arm, and the feeling of her rounded breasts flexing and squishing like bread dough was so pleasant that I couldn't help but be aware of it.
Sayaka's hair, right in front of me, gives off a faint, sweet, milk-like scent.
I remember my sister, who has a strangely keen nose, saying that the handkerchief she borrowed from her had that smell. I wonder if it was the smell of the conditioner or shampoo she uses.
Feeling his heart pounding, Tomoya realized that he couldn't just leave the two of them continuing their friendly quarrel like this forever, and was about to step in to mediate.
"Um... Nakata-san, can I ask you something?"
Suddenly, a boy appeared from behind something and called out to Ayane with a troubled look on his face.
"Who are you?"
The girl with the side ponytail looked up and replied brusquely while still clinging to her brother's arm.
"Well, it's Watanabe from my class... you know, he's on the soccer team! Um, well, can we just talk for a bit?"
Undeterred by this reaction, the boy smiled affably and turned a pleading gaze towards Tomoya and Sayaka, who were watching.
(What is this guy?)
I don't really understand, but it seems like it wouldn't be possible if they were there.
It's a bit worrying whether it's okay to leave her sister alone with a man who has suddenly appeared as her older brother, but it shouldn't be a problem if she keeps an eye on things from a distance.
He looked very serious, and as Ayane's classmate, I couldn't just ignore him.
"Ayane...listen to me."
"...Okay, if that's what you want, let's talk over there."
When I gave her a wink, the side-tailed younger sister sighed openly and walked a little further ahead with the boy.
"He's the talk of the girls, the soccer club's promising new member. But it seems he turns down every confession he gets, saying he has someone he likes..."
"Oh..."
Immediately after she nodded, she saw the boy handing an envelope to Ayane.
(Could it be... a love letter?)
I thought back to what Sayaka had just told me.
The "person he likes" he used as a reason for rejecting his confession is probably Ayane.
The moment I realized this, I felt a sharp pain deep in my chest and involuntarily grimaced.
I wonder how Ayane will respond. I watch with a heavy heart, and then...
"I'm not interested. It's a nuisance, so take it home."
I heard Ayane reply in a completely monotonous, ice-cold voice.
The girl with the side ponytail looked at the boy with no light in her eyes, they were dyed a deep darkness like a starless night sky. Even from a distance, the air seemed to freeze, and it was clear that it was suffocating.
"Eh, uh, n-no, you don't have to reply right away, just read it for now... well... anyway, let me hear it again some other time!"
The boy, who must have come with determination to confess, could not bear it any longer, and after forcing the letter on her, he ran off without looking back.
It would be a bittersweet scene if she was embarrassed and ran away, but her cheeks were pale and twitching, so it didn't look like that at all.
"The whole story of my younger sister's confession"
What should have been a very shocking event for me as an older brother ended in the blink of an eye and in a way that I had never expected.
Tomoya was stunned for a moment, feeling disappointed.
"This morning is the worst."
Ayane muttered in obvious displeasure and began ripping the white envelope she had just received without any hesitation.
"Hey, Ayane!"
"Oh, big brother, I'm sorry for keeping you waiting for such a trivial matter."
The girl with the side tail came running back to her brother, sporting a gentle smile that seemed to belie the cold expression she had when she received his confession.
However, that didn't stop him from tearing the envelope into pieces.
"Well, that's fine, but that letter..."
"Don't worry, I won't scatter them around. I really want to throw away this disgusting thing as soon as possible, but... I'll hold off until I find a proper trash can."
Saying this, Ayane gripped the envelope, which had turned into a piece of paper, tightly and put it in her uniform pocket.
For some reason, Tomoya felt a chill run down his spine, but he knew he couldn't just ignore it, so he took a breath and spoke to her.
"It would be bad to tear up a letter someone went to the trouble of giving to you without reading it."
"Why? The answer doesn't change whether I read it or not. When a guy other than Onii-chan says "I love you," it makes me want to throw up..."
In response to her brother's warning, the sister with a bro complex replies with a puzzled look on her face, wondering what's wrong with it.
"but..."
It's really not polite to trample on someone's feelings. Tomoya was about to continue, but Ayane looked up and glared at him, stopping him.
"Big brother, is it okay for Aya to date a boy who is a complete complete stranger?"
A low, yet powerful voice that is clearly audible.
When asked this question, Tomoya's spine reflexively shivers again and he is at a loss for words.
The complicated feelings from earlier came back to him. He wondered how he would have felt if Ayane had replied, "I'd be happy to."
At the very least, they wouldn't have been able to congratulate him with a smile from the bottom of their hearts.
(But I'm Ayane's older brother... I shouldn't get in the way of my sister's love life.)
"If it's someone Ayane can fall in love with, then it's fine."
I should have replied that, but for some reason the words got stuck in my throat and wouldn't come out.
"I think that at your age, it's too early for you to be dating or anything like that."
In the end, what came out of Tomoya's mouth were words that disguised his true feelings with common sense.
She might get angry and tell me not to treat her like a child. With this anxiety in mind, I wait for Ayane's response.
"Yeah, that's true. Aya is still a child who can't let go of her brother, so it's out of the question for her to date another boy."
"Well, that's how it is... I mean, wow!"
After remaining silent for a moment as if she was deep in thought, Ayane suddenly broke into a smile and jumped onto her brother's chest.
His eyes, now light again, narrow and he rubs his nose against me like a puppy, begging for attention.
"You're sticking too close, get away."
"No! I've been feeling awful since the morning, so let me replenish my Onii-chan energy."
"What's with that big brother thing... Ah, what a hopeless guy."
Although he gave a wry smile, Tomoya didn't try to forcefully separate his beloved sister.
As I felt her body temperature, which was slightly higher than my own, the roughness in my chest disappeared.
"Mmm, I love Onii-chan's smell. Ah... it calms me down."
(He's so spoiled and childish... it's too early for him to fall in love.)
So, for now it's fine as it is.
The brother, who couldn't let go of his sister, gently put his arm around Ayane's shoulders as she innocently clung to him, wagging her invisible tail, and convinced himself of this.
"...Huh."
Without even noticing, her childhood friend with twin tails, who had been completely left out of the loop, was standing right next to her, her expression stiff as if she had made up her mind about something.
"You should stop being such a big sister."
It was during the afternoon break that Sayaka, with an unusually serious expression on her face, started talking.
"What's this all of a sudden?"
"It's not sudden. I've always thought I had to tell you someday."
The childhood friend, with his hands on the table, continued talking while looking down at Tomoya, who was still seated.
"No matter how close siblings you are, Tomoya and Ayane are going too far."
"Is that so...?"
"That's right! Normal siblings at this age wouldn't walk holding hands or hug each other while walking. Of course, that's not all. Even now, when you eat at home, you sit next to each other and feed each other, right? I don't think that's the case, but you still sleep together... or take baths together, that's not the case, right?"
"Uh, no way!! That's a bit much..."
That's true, but he can't admit it openly, so he remains vague.
I turned away pretending not to notice, but I could clearly feel the sharp, suspicious gaze of my childhood friend.
"Sayaka, your voice is loud. Is there something we need to talk about right now?"
Sensing the commotion around them, he put his index finger to his lips and said, "Shhh!"
Along with the warm gazes of my classmates, I could hear whispers.
"Nakata's side is going a bit too far..."
"I'm close with my brother too, but I still don't think I'd hug him, let alone hold his hand. It's embarrassing, and we're not close enough..."
"It wouldn't be strange if they slept together there," "In fact, they look just like lovers," etc. People are now saying whatever they want.
Tomoya wanted to protest, but at the same time he felt a little shocked.
(Did people around me think my relationship with my siblings was that strange?)
I've never compared it to other places, so I've never really thought about it that much until now.
I was aware that we were getting a little too close, but I realized that from the perspective of those around us, our relationship had gone even further than that.
"Do you feel any sense of crisis? To begin with, it's strange that we hardly ever have a chance to talk about this. We're always together at home, at school, and outside... The only times we're separated are during breaks like now when Ayane can't come to school because she has to change for gym class, right?"
"...That's right."
Morning, noon, and night.
Unless there are unavoidable circumstances, such as during class, they are always close enough to sense each other's presence.
I thought it wasn't strange since we were a family living under the same roof, but looking at the stern expression on my childhood friend's face, it seemed that this was also outside of common sense.
"Ayane's attitude this morning... don't you think Tomoya is a problem?"
"Well, well...yeah."
The sight of Ayane tearing open the envelope with a cold expression on her face was certainly spine-chilling and terrifying.
"Ayane-chan, your personality changes drastically when Tomoya is involved."
Sayaka's face clouded with worry as she spoke, and the boy could relate to what she was saying.
Just like this morning, whenever I try to distance myself from Ayane or say something that pushes her away, it can create that kind of unfathomable fear.
"If things continue like this, it might be difficult to build proper relationships with others. It seems like she doesn't have any particularly close friends in class..."
"Now that you mention it... I've never heard him talk about his friends."
I almost always spend my holidays with myself.
He has never brought any friends other than his childhood friend Sayaka.
"Even Tomoya... If he's always stuck with Ayane-chan, he'll... I mean, he won't be able to find a boyfriend. That would be a problem, right?"
"Hmm, I wonder. To be honest..."
(I'm not really interested, as long as Ayane is by my side...)
He muttered to himself, trying to avoid saying anything, knowing that if he spoke out he would get scolded again.
However, his true feelings were immediately known to his childhood friend.
"Tomoya, you and Ayane are brother and sister! You can't stay kids forever. You have to grow up, find your own partner, and move on to new paths... Brother and sister can't be lovers. You understand that, right?"
"...ah"
Those words made Tomoya feel a sharp pain deep in his chest.
It's a reality that we are well aware of, but still hesitate to speak out.
"I'm not old enough to be conscious of it yet," he had used that excuse to turn a blind eye to the issue, but when Sayaka, who had always been by his side watching over them, gave him a serious warning, he could no longer ignore it.
"Let's slowly distance ourselves from each other. At the very least, we can become normal siblings who get along well."
The boy just bows his head and remains silent as his childhood friend tries to advise him.
"If they're siblings, it's not weird."
Tomoya had been using such words as an excuse to get by, but he realized that he had reached his limit.
(It's lonely, but... it can't be helped. Ayane and I are siblings after all.)
"Oh, wait, big brother!"
That evening, Tomoya left school early after class, wanting to think for a bit, but halfway home he was stopped by a familiar girl's voice.
"Why didn't you wait for me today? Aya, I went to your classroom right after homeroom."
Ayane, with her cheeks puffed up like a hamster's, ran up to her brother, her long side-tail hair swinging.
He stood next to her and, quite naturally, tried to embrace her in his arms - but
"Sometimes I just want to go home alone."
Tomoya held back the urge to just let her do whatever she wanted and started walking quickly, pushing away his sister who was playing around with him.
"...big brother?"
Perhaps taking this as a rejection, Ayane's face was pale and bloodless, and her eyes were wide open.
Tomoya's heart tightened when he saw his sister like that, but he tried desperately to endure it.
If I get swept away here, it'll be business as usual again.
"Ayane, we're not kids anymore. Um... I think it's about time we stopped being so close. People around us think it's weird..."
"What's that? What happened all of a sudden?"
My younger sister asked, her shoulders slumped in despair and her eyes looking up.
His depressed state almost moves me, but I hold myself back and continue talking.
"No...Sayaka told me. She told me it's time to let go of my sister..."
Right after I explained the situation.
"Yeah... that's it. You deceived your brother with such a plausible excuse, and tried to tear your relationship with Aya apart. That's ugly jealousy, Sa-chan."
His beloved little sister spat out these words, her pupils now dark and seemingly extremely small. She exuded a murderous aura and unfathomable force that was far more intense than any sullen look he had ever seen her in before, making even her brother take a step back without thinking.
"No, he wasn't trying to tear us apart, he was just genuinely worried about us..."
Tomoya tried to protect his childhood friend who had kindly warned him, but...
"No!"
Ayane's scream, stomping hard on the asphalt, kicking up a cloud of dust, drowned out what he'd been saying.
Her body, which is more than a head smaller than mine, appears to be more than twice as large, perhaps due to an optical illusion or a black aura rising from her back.
Perhaps sensing the uneasy atmosphere, a pigeon that had been perched on a nearby fence flew away in a panic.
The intimidating feeling that he was being swallowed up made Tomoya unable to stop the cold sweat from running down his forehead.
"Sa-chan wants to take your brother away from Aya, so she's trying to deceive you by saying things like that. What's wrong with siblings getting along? Isn't it strange?"
The side-tailed little sister approached with strong strides, as if stepping over something. The girl who was always innocent and cute, like a puppy, now looked to Tomoya like a wolf with bared fangs.
I almost reflexively agreed with him, "That's right," but I managed to hold back.
By being too close to Ayane, he ends up closing her off to other people.
Considering the future of my precious little sister, I can't let myself be swept away here.
"...Even when we're getting along, there's an appropriate distance between siblings, right? You don't have to stick to me forever, Ayane, you can make friends in class, and..."
She couldn't bring herself to say "even one of the boys I like" and remained vague.
"Big brother, are you sure that's okay?"
My sister asks in a monotonous voice, her emotions unreadable.
Even so, she continued to stomp her feet forcefully as if to express her frustration, and her long brown hair in a side ponytail swayed slightly in time with her footsteps.
(Not good though...)
Unable to contain himself, Tomoya averts his gaze and swallows the complicated emotions welling up inside him.
For the sake of her sister's future, she must endure the heart-wrenching loneliness.
Clenching his fists so tightly that his nails dug into his palms, he answered with determination.
"Let's think about it for a bit. It's for Ayane's sake."
"I see. Big brother believes Sa-chan's lame words more than Aya's."
"Eh, no, it's not like that..."
Ayane's mouth twisted into a cold smile, and with that said, she ran off as fast as she could, her long side-tail hair flying wildly.
The brother who was left behind was unable to chase after him, and could only watch in amazement as his brother's back, which exuded a cold aura of rejection, seemed to reject everything.
"Ayane... are you back?"
Tomoya walked home with weak steps, taking nearly twice as long as usual to get home. After checking that his beloved sister's shoes were in the entranceway, he muttered.
I couldn't shake the bad feeling that he might have just disappeared somewhere, but it seems the worst-case scenario was avoided.
(But we have to talk properly...)
This is not something that can be left unresolved.
Remembering Ayane's gloomy expression earlier makes me feel heavy-hearted and my stomach aches, but for her sake, we need to talk it out until we both come to an understanding.
With determination, I looked into the living room, but Ayane was nowhere to be seen.
She's probably in her room on the second floor.
"Ayane's room... Come to think of it, it's been a while."
Since he reached a certain age, he has felt somewhat embarrassed about visiting a girl's room, and has never set foot in Ayane's or his childhood friend Sayaka's private rooms.
Even at a time like this, for some reason I feel strangely aware of it and my heart starts beating faster.
(What am I doing? I was just going to my sister's room.)
Holding the left side of my chest, I climbed the stairs and took several deep breaths as I stood in front of Ayane's room.
I stare at the door with a cute heart-shaped nameplate hanging on it for a while.
There was no sign of anyone in the room. Either they were out, or they were just depressed and silent.
Although he hesitated for a moment, Tomoya made up his mind and knocked.
"Ayane, it's me. Um... I'd like to talk to you for a bit. Can I come in?"
"...Okay."
When I called out, a weak voice answered almost immediately.
It seems he's not so upset that he doesn't even want to talk.
Feeling a little relieved, Tomoya timidly opened the door.
"Whoa!"
When I saw the inside of the room, I was left speechless.
Countless photographs are pasted on the four walls with almost no gaps between them.
I only took a quick look, but they all feature the boy who is my older brother.
From childhood to more recent times, there are many photos that I don't know when they were taken.
"What's wrong? ...You can come in."
Ayane urged her brother, who was standing still, to sit cross-legged on the bed.
She must have changed clothes as soon as she got home. Instead of her uniform, she was wearing a pink one-piece dress with white frills, a cardigan, and a matching pink ribbon headband, the kind of casual clothes she likes to wear at home.
The large bath towel the girl with the side ponytail was carrying around her shoulders looked familiar.
It must be one of my old things that I had asked her to throw away a while ago because it was old.
Upon closer inspection, he noticed that his personal belongings, such as handkerchiefs, mechanical pencils, shirts, and shoes, which he had thought he had thrown away, were lined up on the shelves.
"Oh, excuse me for interrupting... Wait, what's this photo and this...?"
For now, I go into the room, close the door behind me, and without letting it go, I lunge at my sister.
"It's a nice room, isn't it? When I'm here, I can feel like I have Onii-chan by my side... I can do my best even when something really bad happens."
Ayane smiles as she rubs her cheek against the large stuffed animal she is hugging.
The humanoid figure, which was probably handmade, was modeled after Tomoya, judging from the hairstyle and the clothes he was wearing.
"With me by your side...right?"
"No matter how close siblings are, this is going too far."
The advice of a childhood friend crosses his mind.
Seeing this room made me realize once again that this was no exaggeration.
(I'm happy that she's so attached to me, but... there's a limit to what you can do, after all.)
The room looked just like the "Nakata Tomoya Museum," and a cold sweat ran down my back.
I really need to have a proper talk with her.
"Umm, I'd like to continue what we were talking about earlier..."
I was a little worried about how to advise my sister without hurting her feelings, when I started to talk about it.
"This is going to be a long story, right? Hold on, Aya, I'll go make some tea."
"Uh, uh... yeah."
With that, Ayane leaves the room, and I watch her go without stopping her.
The shock from the room was so strong that I'm still confused. I need a moment to clear my head.
"When did you take this photo? ...I mean, there's even a sleeping face in it."
While looking at the photos, which number so many that they could serve as wallpaper, I pick up the stuffed toy that looks like me and is placed on the bed.
The detailed craftsmanship, typical of Ayane's dexterity, makes it seem more and more similar the more you look at it.
As I looked at it, I noticed small stains around the mouth and hands.
(Maybe she was crying while holding a stuffed toy...?)
When I casually brought my face closer, a faint sweet and sour scent wafted from the air.
It's a far cry from the dusty smell that's typical of fabrics.
Perhaps it's lightly perfumed?
"Well, well... it's fine. Anyway, this room... you know."
It's best not to think too deeply about it. With that premonition, I toss the stuffed toy onto the bed.
He waited for about ten minutes, holding his head and looking at the room, which proved more than anything else how excessive Ayane's feelings for him were.
"Sorry to keep you waiting, big brother. Iced tea would be fine, right?"
Ayane, seemingly in a better mood, returned to the room with a smile and two glasses filled with a vibrant reddish-brown liquid.
"I put gum syrup in it. Big brother, you really like sweet things, don't you?"
"Oh, yeah. Thank you."
I thought the discussion would be as tense as it was on the way home, but it looked like it would be resolved peacefully.
Feeling a bit relieved, I took a sip from the glass that was handed to me.
"Hmm...? Doesn't this taste a little different from usual?"
The moment he took a sip of the chilled reddish-brown liquid, he frowned in discomfort.
The sweetness of gum syrup and the refreshing aroma of black tea are mixed together with a slight saltiness and iron smell that is not usually felt.
Taking another sip, I could smell a slight sweet and sour scent.
I remember smelling it somewhere. After thinking about it for a moment, I realized it was very similar to the smell I had smelled from the stain on the stuffed toy earlier.
"Ahaha, Onii-chan, you noticed right away... I'm so happy."
Ayane gazed at her brother tilting his head, her cheeks flushed crimson with a look of ecstasy and joy.
A strangely hot breath spills from her parted lips, creating a seductive atmosphere.
"You noticed... no, what's going on?"
Something was clearly not normal. Seeing the ecstatic expression on her face, Tomoya looked back and forth between the glass in his hand and his sister and asked a question.
"Since you don't understand my feelings, I mixed a lot of my feelings into it so that you can understand it properly. Is it delicious? It's Aya's taste, that is..."
My beloved sister places her palms on both of her flushed cheeks and smiles with the corners of her eyes drooping.
Don't pursue this any deeper.
Tomoya instinctively realized this, put the glass he was holding on the desk, and sat down in a chair.
"Well, hey, listen to me for a second. It's not that I've grown to dislike Ayane or that she's getting in the way or anything. I just... as normal siblings... eh?"
Just as I was about to start talking, I was hit with a strong dizziness, as if I had been hit on the side of the head. My limbs became numb, and I lost all feeling in my body, as if it no longer belonged to me.
"This...what is..."
"Are you okay, Onii-chan? I'm sorry, I really just wanted you to enjoy Aya's taste, but... it seems you've been completely fooled by that evil woman, so I thought you didn't have time."
Ayane bends down and gently catches Tomoya as he begins to fall forward.
She rubbed her cheek against his and whispered in his ear, her voice hot and high-pitched, exuding a bewitching sexiness he had never felt from her before.
"What on earth...are you planning...?"
(Could that have been medicine? That iced tea just now...)
When he realized this, the numbness spread to his head, and Tomoya buried his face in Ayane's soft hair, which was tied up in a side ponytail, and lost consciousness.
"Mmm, Big Brother's scent. Mmm, it calms me down..."
Her voice was sweet and nasal, like honey, and it tickled my chest.
His consciousness, which had been submerged in darkness, gradually rose, and as Tomoya slowly opened his eyes, what came into view was the sight of his sister leaning over him, burying her face in his exposed chest.
She pushed the front of her dress, including her bra, down, revealing almost all of her ample breasts. Her spilling breasts rested on the boy's stomach, and with a look of delight on her face, she rubbed her nose and cheek against his chest.
"Oh... right...?"
"Hmmmm... Ah, good morning, big brother ♪"
"Good morning... No, what are you doing... Huh?"
The boy tried to jump up, but frowned when he realized he couldn't move his arms or legs.
I shook my head gently, still feeling a dull pain deep inside, to regain consciousness and reassess the situation.
He was lying on the bed in Ayane's room, his arms and legs spread out, tightly bound to the bedposts with leather handcuffs.
Even if you try to move, it just makes a small creaking sound and doesn't budge.
"What is this?! Where did you get something like this..."
Tomoya, who has a vague memory of what happened after drinking the iced tea, screams in confusion.
I don't want to believe it, but I think it was laced with some kind of sleeping pill.
It's a shock to be drugged by his beloved sister, but he's also shocked by the mysterious handcuffs that are restraining him. He doesn't understand what's happening, and he doesn't want to.
The side-tailed sister, who had been staring at her flustered brother, looked apologetic, lowered her eyes, and looked away.
"Aya didn't want to do anything rough either. Ideally, we would have liked to do something that would become a fond memory for both of us... but..."
"But... what is it? Did you really put something in that iced tea just now? No, but where did you get something like that!? The same goes for these handcuffs."
"You can buy anything online now, you know? We live in a convenient world."
Ayane smiled mischievously and buried her face in Tomoya's chest again.
As always, he presses his nose against me with the innocence of a puppy playing.
He seemed more excited than usual, and his hot breath was constantly blowing against my skin, tickling me so much that I couldn't stay still.
With his hands and feet tied, he could not move and could only arch his back and writhe in agony.
"It tickles, Ayane. Hmm, n-no, that's not the problem!!"
Not understanding his sister's out-of-control behavior, he questioned her in an unusually strong tone - and immediately afterwards.
"It's your brother's fault!"
My younger sister glared at me with her dim blue eyes and shouted back in an even more furious voice.
The hands that had been pressed against his chest tightened, and his toes dug deeply into his skin.
The boy instinctively winced at the force and sharp pain and remained silent, but his beloved sister, fired up, continued speaking in rapid succession.
"Big Brother only has eyes for Aya, and Aya only has eyes for Big Brother. That made me happy, so why are you saying something so cruel like you want to distance yourself? For the sake of your future? Aya doesn't need a future where she's separated from Big Brother! I'd be happy just being by your side…living surrounded by your scent and kindness. I don't need anything else."
"...But we're brother and sister. Someday..."
"Each of us has to find our partner and walk a different path."
Tomoya wanted to tell her such an obvious thing, but he couldn't say anything further.
I can't say anything bossy to Ayane. I think of her as too special.
Even though I know that it's not allowed.
As if sensing Tomoya's conflict, Ayane smiled.
"It's okay, Onii-chan. No matter what others think, as long as I have you, I'll be happy. We eat meals together every day, take baths together, and sleep together. As long as I can always be close enough to feel you... that's what I was putting up with."
The girl with the side-tail hair stopped talking, took a deep breath, pressed her nose against the boy's chest again, and slowly slid closer to his neck.
"Ever since we were little, you have only had eyes for me and protected me... You are my own beloved prince... Hehe, that's why... I've always held back my feelings, telling myself not to cause trouble or cause trouble for you... nfu, haa, kiss..."
"Ah, ahh! Hey, wait a moment, Ayane!! What are you doing...ahhh"
Ayane whispered in a dreamy, hollow voice, and placed a pecking kiss on her brother's neck.
Once, twice, three times. Each time her flushed, cherry-colored lips touched him, the force of her sucking grew stronger, leaving numerous red marks on his neck.
"Wait, Ayane. Calm down...please."
With a slight pain and a burning throbbing in his voice, Tomoya repeatedly pleads with his out-of-control sister to somehow stop her.
However, the girl with the side ponytail, her cheeks relaxed in ecstasy, continued to shower kisses, moving up from his neck to his jaw.
"I love you. I've always loved you, Onii-chan. You're a kind and reliable Onii-chan who's always been by my side and thinking about me... It's impossible not to fall in love with someone like that, right?"
"N-no, I think of Ayane as my precious little sister... well..."
Tomoya is unable to clearly respond to his sister's passionate confession and remains vague.
It's true that my feelings for her have grown too much to simply call her my "little sister."
The sister continues to confess to her brother, who looks away feeling awkward.
"Aya, as long as she has her big brother, that's all she needs. It doesn't matter if her mom, dad, or any of her friends are gone. As long as her big brother is only looking out for her… that's all."
Ayane, her eyes moist with light, murmured as she pressed her lips to Tomoya's cheek.
He made a loud, deliberate sucking sound, then stuck out his tongue and began licking there enthusiastically like a real puppy.
"Shh, Big Brother's scent... the scent that's always been close to Aya... Mmm, I love it... I really love it. Your soft cheeks. And those eyes... You're usually cold, but I love the gentleness in your eyes when you look at Aya. I love everything about you, Big Brother."
Ayane licked her cheek several times to spread saliva over it, then raised her body slightly and looked directly at Tomoya, their noses touching.
Her eyes sparkle with a bewitching fascination, as if she is intoxicated, and she exudes a bewitching aura that makes it hard to believe that she is the little sister I always thought of as a spoiled child.
As he stared, breathless and mesmerized, Ayane gently closed her eyes and brought her slightly pouted lips closer to the boy's mouth.
"W-wait... that's not good! We're brother and sister, huh, lips."
"I know. That's why you were holding back, Aya? You wanted to keep things the way they were until you and your brother could move out on your own, in a place where no one knew you… a place where people would see you not as "brother and sister," but as "lovers"… no, as "husband and wife."
"Huh, husband and wife? No, that's not possible..."
The boy's eyes widened and he was speechless at the shocking words that came out of his sister's mouth.
I want to leave this city someday and live far away. So, I want you to come with me.
I have heard such dreams for the future jokingly many times.
I never thought that that was what it meant.
Immediately after that, I realized that my sister's feelings were genuine.
"It's a little early, but... from today let's be husband and wife, Onii-chan. Hehe, should we start off as lovers? But we've always been brother and sister like lovers up until now... so it's fine. So, this... is our kiss to seal our marriage vows. We swear before God that we'll love each other forever... haha."
Ayane said this with a dazzling smile that sounded genuinely happy, and before Tomoya could even turn away, she pressed her lips against his.
"Fuh, mh, chu... ahh"
The mouth is covered with a meltingly hot sensation, and the comfort makes my whole body relax.
Then the tip of his wet tongue is inserted between the gaps in my loose lips, and he licks the inside of my cheeks and the bases of my teeth, tickling them.
Before I could even resist, my tongue was grabbed and I was sucked wetly, smearing saliva all over it from base to tip.
The refreshing lemon-like scent filled my mouth, making me realize that my sister and I were passionately kissing each other as lovers.
"Hmph, haa, Ayane, wait a moment... ah, ah."
"I won't wait, ngh, I've been putting up with being your 'little sister' for years, and it's your fault for trying to separate from Aya without knowing that! I'll never hand you over to Sa-chan or any other bitch... Aya is the one who loves you more than anything in the world, and she's the one who understands you the best... There is no other girl worthy of you other than Aya, who has always been with you!! I'm going to make you understand that from now on. I'm going to teach you, big brother, with your ignorant body...♪"
Ayane muttered in a terrifying voice between kisses, and then she suddenly reached out her right hand towards her brother's crotch.
Just as I felt someone groping me there, the zipper of my pants was pulled down and the man's shaft hidden inside was taken out.
"Kyaah... mmm, aha, big brother's penis... it's already rock hard."
"Hmmm, kiss, hmmm, that's..."
Perhaps it was because he was intoxicated by Ayane's passionate kiss and the lustful atmosphere she created, that his stiff penis was so hard that the veins were visible on the surface of his penis, and it was pulsating slightly.
Even when he barged into the bathroom, he had desperately tried to hide his private parts with a towel, but his side-tailed sister licked her lips and grabbed them with her right hand without any hesitation.
"Where are you touching, Ayane? There..."
"Cock... Ah, I should say dick, right? Big brother, I have a fetish for getting turned on when girls use vulgar words."
"Huh!? Ah, ah..."
"Aya knows a lot about big brother's dick. Lol... look at this healthy, erect dick... I'll make you cum in no time. I'll make you squirt pure white semen."
"How did you know that?" Tomoya screams voicelessly, his eyes wide.
While continuing to kiss her brother, rubbing their tongues together vigorously, Ayane began to violently stroke the penis she had grasped up and down.
The shaft is gripped with such force that the pads of the fingers dig into it, and rubbed from the base to just below the shaft.
The force he used was just as strong as when the boy comforted himself, but the warmth and softness of his palm was completely different.
It has a slightly warm body temperature and feels as smooth as silk. When rubbed, it feels as if the epidermis slowly melts, exposing the pleasure nerves.
A strong, fainting ache erupts over and over again, and my breathing becomes increasingly heavy.
"Hmmm, haa, wait... Ayane, that... ahh, ahh!"
In between kisses, she tries to stop him with a trembling voice, but she can't even form the words properly.
Not only his shaft but his entire lower abdomen goes numb with the electric current of pleasure, causing his hips to shake pathetically.
"Suck, lick, hmm, it feels good, doesn't it? Aya... I really do know everything about Onii-chan. I even know which parts of his penis are sensitive. That's because... I've secretly peeked on you many times while you were doing it alone."
"Wha, hmph, th, that's not true..."
"I'm sorry, I wanted to please you like I did today... nfu, to make up for it, I'll show you Aya doing it by herself next time. No, I want you to see... I want you to use photos of you and your laundry as your masturbation material... Aya playing with her pussy in a naughty way."
His beloved sister uses obscene words to tickle Tomoya's sexual desires, and moves her hands frantically.
Instead of just stroking it up and down, she also began to raise her fingertips and tickle the underside of his penis with her nails.
He then flicks the protruding head of his penis hard with the base of his thumb and index finger, teasing him.
"Hmph, ha, wait, ah, Ayane... there, hahi, uuh!"
It's a movement I don't remember making when masturbating, but the pleasure it gives me is intense.
A strong, tingling sensation explodes at the base of my rod, and I feel like my legs are going to give way.
Her sister had clearly seen her embarrassing moments. Before she could writhe in shame and want to cover her face, she simply let out a sweet, high-pitched voice.
"You can feel it, right? When Onii-chan was doing it, I was watching closely to see which part of him was touching you to make the most pleasurable noises."
"Ahh, ha, Ayane... please, stop... ugh, ah! I, ugh, if you do this any more... ohh, I can't take it anymore! Ahh, ah, ugh, ugh"
"Yeah, Aya can't help it either. I can't wait to see Big Brother ejaculate... I can't hold back any longer, I want to see Big Brother ejaculate inside Aya. Aya's hands and pussy feel so good. It's okay, from today Aya is your wife, your sister but you're still your wife! Cum so hard you can impregnate the palm of my hand♪"
Ayane changed her kiss from one where her tongue was entangled to one where she was pecking at his lips repeatedly, and as she looked closely at the writhing Tomoya, she urged him on in a hot, high-pitched voice.
Then, as if to add insult to injury, he slowly slides his upper body back and forth.
Her breasts, which had been pressing forcefully against his stomach, began to soften and change shape with her movements, relentlessly rubbing against the boy's solar plexus.
It's softer than it looks, and yet when it's compressed to a certain extent, it has a strong elasticity that pushes back. The unique friction that you can't get anywhere else feels more than enough to make your stomach feel good, even though it's not a direct erogenous zone.
The feeling blends seamlessly with the throbbing in my lower abdomen, and my consciousness quickly fades away.
"Ahh, my dick is twitching. Come on, let it out. Cum with Aya's hands♪"
Along with Ayane's joyful, bouncy voice, the tip of his swollen glans and the opening from which clear fluid was overflowing were pushed open firmly with the pad of his thumb.
The urge to ejaculate, which he had been holding back by a hair's breadth, suddenly bursts forth, and his consciousness drops.
"Wait, ah, Ayane... I, I... ahh, ahh!"
Slurp, splash, splash, splash!!
Immediately after the shaft gripped tightly in Aibou's hand swelled up a size larger, a hot white liquid spurted out from the opening, pushing back the thumb that was placed on it.
"Kyaah, aha... It's coming out, Big Brother's semen! It's amazing... A lot more is coming out than when I masturbate. Does it feel good with Aya's hand after all? Is a lot of semen coming out too?"
The side-tailed sister watches the white liquid spurting out while cheering.
With her grip on his shaft tightly, Tomoya continues to ejaculate without being able to stop.
(What is this... it feels too good... and I can't stop!)
As the hot liquid rose up through my constricted urethra, I felt such intense pleasure that I thought my shaft might explode.
Unable to stop the spasms in his hips, he lets out hot sighs from his lips, which are coated with his sister's sweet saliva, as he continues to ejaculate.
"Your ejaculation is really impressive, Onii-chan. Aya, I've secretly watched Onii-chan's ejaculation many times, but... I've never seen so much come out. Ah, I'm so happy! I can feel Onii-chan's love through his semen... Mmm, I'm so happy I might go crazy."
As if unable to hold back any longer, Ayane let go of his stiff penis and caught the gushing semen in the palm of her right hand. When the long ejaculation was over, she even scooped up the semen that had splattered all over the place with her fingers.
"It's pure white and trembling. The semen that my brother released for me... hah, hmm... it smells green. A strong smell that stings my nose ♪"
Ayane narrowed her eyes, her tongue hanging out lazily, and out of breath, as she began to slurp up her brother's white liquid that had filled the palm of her hand while muttering like she was in a daze.
"Ugh, ah, Ayane, what are you doing..."
"Slurp, mmm, mmm, mmm! Haa, aha, it's delicious... Big brother's taste and smell is seeping into my mouth and stomach, haa, haa, more, more...♪"
The girl with the side ponytail, her mouth full of semen, rolls it around in her mouth as if gargling, letting out a cry of delight, and then gulps it down without any hesitation.
As if she still wasn't satisfied, she licked the remains from her palm with her tongue, and then smeared the little that remained on her flushed cheeks and forehead.
"I love you, Onii-chan, I love you so much! Hmm, ahh, please stop, Aya, I'm going to cum just from Onii-chan's semen... hmm, I'm going to cum, haa, ahaa!!"
Ayane, with a thin layer of stringy semen smeared all over her face and her cheeks relaxing in ecstasy, exuded such a bewitching sexiness that it was hard not to stare.
Although he knows he has to stop her, Tomoya is captivated by her allure, which is completely different from her usual innocent self, and is left speechless.
She was so delighted by my liquidy liquid, melting in ecstasy. It made me realize her love for me once again, and even though I knew it was wrong, I couldn't hide my joy.
The sound of his heartbeat grew loud enough for him to hear clearly, and the blood being pumped out from there flowed with furious force into the flesh spear that had just finished ejaculating.
"Ahh, ahaa... I'm sorry, Onii-chan. Aya, you're enjoying yourself by yourself... But Onii-chan still isn't satisfied, is he?"
The side-tailed younger sister noticed this and licked the semen off her mouth, then twisted her lips in delight.
When Tomoya saw this, for some reason, a chill ran down his spine and his expression stiffened.
What was about to happen? A bad feeling filled my heart, and I flailed my arms and legs in an attempt to break free, but I just couldn't tear the strong leather handcuffs off.
"Big brother, what's wrong? Is your dick in pain and you can't stand it? Hehe, I'm sorry. Aya will make it easier for you right now."
With that, the little sister with the side ponytail stood up and, without any hesitation, threw off her cute pink lace shorts and placed them on the bedside table.
At that moment, a sweet and sour refreshing scent wafted through the air.
I'm sure I've smelled it a few times today.
Tomoya snorted reflexively, and his sister, seeing this, tilted her head slightly in embarrassment.
"Big brother, Aya's naughty scent...don't smell it so much."
"Ah, I, I'm sorry. But, no, more importantly..."
"Hehe, faster than that... right? Yeah, I know. Aya's body is getting hot from your semen... and I can't hold back any longer. Is that okay? Make me your wife right now, Big Brother ♪ Even if you say no, I'll do it."
The girl with the side ponytail muttered, her eyes exuding an indescribable intensity as she lightly lifted her skirt and sat down around Tomoya's waist.
I had unavoidably seen it a few times in the bathroom: a thin bush the same color as his hair, and a straight vertical line hidden behind it. Transparent drops dripping from it hit the tip of his erect, still standing upright.
The slightly thick consistency is proof that my sister is in heat as a woman.
Tomoya was surprised at the amount of liquid, which quickly made his entire glans wet, but when he realized what she was trying to do, his eyes widened again.
"Wait a minute, Ayane! You can't... No, that's not okay!!"
"Why? Big Brother's dick also wants Aya to be his wife."
"This is... well..."
No matter how many times he yelled in his mind to calm down, his erection remained hard, swelling with the taboo excitement of being with the sister he had secretly loved. In fact, it grew in strength, and instead of remaining vertical, it looked as if it was going to stick to his stomach.
"Big brother's dick is so energetic ♪ I'm sorry, I wanted to do it with Aya quickly and I couldn't hold back. It was painful and difficult... That's why I got distracted by Sa-chan."
Ayane nodded in agreement, gazing lovingly at her brother, Gocho.
"No, that's not true at all. Sayaka was just genuinely worried about me and Ayane..."
"You still say that? Sa-chan just wants to steal your big brother away from Aya. You act like you have common sense... how unfair!! Ah, but that's over now ♪ Big brother is now Aya's husband... I'm going to rub Aya's scent into every inch of your dick."
Ayane hysterically shouted at Tomoya, who had tried to protect her childhood friend, then she once again flashed a smile of ecstasy that hinted at madness, and grabbed her brother's shaft with her right hand.
"Big Brother is worried about Aya, isn't he? Even though she's your little sister, she wonders if it's okay for you to become your wife? Hehe, it's fine. I don't care what the flies and bitches around me say. Aya will be happy as long as you're with me. I'll do something about anyone who gets in her way... so Big Brother, please only look at Aya. Only love Aya ♪"
Before Tomoya had a chance to interject, Ayane expressed her passionate and earnest feelings as she placed the tip of the penis she had grasped against her own slit.
Squelch. The moment the sound of water pushing through her wet flesh was heard, Tomoya dropped his hips with a thud before he could say anything.
Slurp, slurp, squelch!
"Ugh, ugh, ahhh, ahhh! This, ugh."
"Ahh, ahhh, it's coming! My dick, my big brother's dick is entering Aya, he's come to propose to my womb that he'll make Aya his wife!!"
As Ayane moaned in agony, her long hair in a side ponytail tossed about, the tip of her stiff cock, wrapped in a mucous membrane so hot it was almost burning, pressed tightly against the slightly hollowed end of her vagina. The vaginal walls, clinging to the shaft, rippled violently, and the opening of her hole contracted tightly as if to say it would never let go.
"Ayane, w-w-it's in. Really."
He lifted his head slightly and peered down between her legs, seeing his own penis thrust straight into the center of his sister's wet honeysuckle. The juices gushing out of her tightly spread vaginal hole were now stained red, unlike the clear juices from before.
The blood is proof that he, the brother, has taken his sister's virginity. The sight is inescapable, and Tomoya becomes dizzy and loses consciousness.
"Hmm, ha, I knew it but... Onii-chan's dick is big. It's filling up Aya's pussy. This... hmm, ha, aha, ha, it feels like it's going to tear..."
"Ah, Ayane, don't push yourself! Just pull it out quickly..."
The boy came back to his senses when he heard his sister's painful, panting voice and hastily urged her on.
He tries to pull his hips back and pull out, but Ayane is sitting there rubbing her small butt cheeks against him, so he can't get away in this position.
Ayane's lips were slightly parted, drool dripping from the corners of them as she gazed up at the sky in a daze.
I'm completely dazed, but I have no choice but to ask her to do something about it.
"Hey, you can't do this! We're brother and sister after all...Hey, Ayane!!"
"It's okay, it's okay! Aya loves you so much, so I don't care what anyone else thinks... Even you've made your dick so big with Aya's pussy... You can't deceive yourself like that! Love me honestly... Make Aya your wife... haha, ha, move, already... aha, ah♪"
The side-tailed younger sister shouted in a strong tone, as if to shake off Tomoya's persuasion, and began to shake her body, bouncing her buttocks.
Slurp, squish, squelch.
An obscene sound of water that I had never heard before echoed through the room.
The flesh pot tightens with greedy intensity, wriggling madly down to every wrinkle on the wall. Inside, the stiff penis moves back and forth in time with the movements of my beloved sister's hips.
"Ugh, ah! Ayane, don't move!! Wh, ah!"
The dark red trunk is swallowed and spit out by the opening, which is overflowing with evidence of defloration.
As he somehow managed to lift his face and peer at the lewd sight, an ecstatic pleasure spread throughout his lower abdomen, as if his penis was slowly melting away.
The shaft, smeared with plenty of hot nectar, is sucked passionately by the squirming flesh walls, and the glans is licked and rolled around by the deepest part of the cervix, which hits it at short intervals.
When my sister touched me just now, I was surprised that such pleasure existed in the world.
However, the pleasure he was experiencing now easily surpassed even that.
Every time I exhaled, a tingly, pleasant numbness reverberated all the way up to my head, and my rationality was instantly shattered.
"Mm, aaah! It's tingling, my pussy is being stretched wide by Onii-chan's thick cock... hmm, haa, it's a little hard to breath... but th, that feels good. It hurts because it's my first time, but that makes me happy! The happy pain that Onii-chan is giving to Aya, the pain of a wife... I want to feel it more, more♪"
Ayane thrusts her hips without rest, complaining about the pain and pleasure of her first experience.
She sat down so deeply that her buttocks pressed tightly against Tomoya's waist and were lightly crushed, and she took his shaft into her vagina all the way to the base. Even her cervix, which should normally be closed, opened up to welcome her beloved brother, and the tip of his swollen glans was buried there.
"Mmmmm! That's deep, Ayane, even that far... ugh!!"
The tightness was even worse than at the opening of his vagina; his most sensitive parts were squeezed to the point that they felt like they were being torn off, and the intense stimulation left Tomoya writhing pathetically.
"It's okay, Big Brother. Aya is your wife now, so you can do whatever naughty things you want to her. Ah, I'm so happy, it feels like my pussy is being disciplined by Big Brother's dick ♪ I've always, always imagined him doing this to me!"
The girl with the side ponytail looked down at her writhing brother, her bewitching indigo eyes scanning the room.
He looked at the countless photos and personal belongings of Tomoya that were on display, and at the man himself panting beneath him, and he placed his hands on his cheeks, which were flushed red as if overcome with emotion.
"Aya, I'm surrounded by lots of big brothers ♪ This is good, this is good. Big brother and Aya... we live in a world just for the two of us, I want to live that way ♪"
"Hmmm, haa, Ayane, please... wait... wait... hmmm, aahh"
Tomoya struggled, rattling the chains of his handcuffs, but that was the best he could do.
His stiff penis was easily broken down in the hot vaginal cavity, and his pleasure nerves were now exposed.
As Ayane moves her hips, an insane pleasure runs through her entire body, blowing away her consciousness, and all she can do is let out a cry of joy from her loosened lips.
"I love you, Onii-chan! Let's stay together forever, and just look at Aya. Look, my dick is already twitching and trembling unstoppable. Do you want to cum? I want to cum like just now, in Aya's pussy."
The younger sister, driven wild by her love for her older brother, moves her hips in a circular motion with her buttocks firmly lowered.
As the head of his penis rubbed against his cervix without any restraint, Tomoya became clearly aware of the hot sensation that had been building up at the base of his penis slowly rising up his urethra.
As if he had reached his limit of endurance, his shaft jumped up and down, and the tip of his penis, licked up by the dead-end mucous membrane, opened wide and sloppily.
"Cum, let's squirt out the juices from your penis. Aya is now your wife, so it's okay for me to have lots of semen in my uterus. It's only natural that I'll be carrying your baby, so I don't want you to get me pregnant right now!"
"Getting pregnant... that's not okay, absolutely not... ngh, aaah!"
There was one line he couldn't cross. Tomoya tried to plead, gathering up his shattered rationality, but the pressure in her vagina grew stronger, blocking his words.
His erection, now thicker than ever before, is compressed until it shrinks a size.
The suffocation became the ultimate stimulation for his melted flesh, and he could no longer stop the powerful pulsations that signaled his approaching ejaculation.
"You have to get Aya pregnant, Big Brother. Once Aya's belly gets bigger, neither the creepy men who know nothing about her like this morning, nor the evil childhood friends who are after Big Brother, will be able to get close! So, hurry up and let it out!! I'll get Big Brother's baby inside Aya's womb and become your real wife, I want to be! I don't want to be just a little sister anymore! I want to be your wife ♪"
Driven wild by her overwhelming love for her brother, Ayane sprints forward, shaking her long hair wildly.
She shook her body up and down so quickly that the ribbon headband on her head almost fell off.
The twin hills of her breasts swayed heavily with her movements, and the pink protrusions at their peaks were hard and pointed, as if to express her joy.
Tomoya, gazing up at the voluptuous sight and the sweet, melting face of his sister, was at the mercy of the boiling heat of his vaginal jar and the pleasure of being rubbed, and he could only allow his stiff cock to be devoured.
(To Ayane... to have my sister have a baby... that's so ridiculous...)
This is absolutely unacceptable.
Even though I knew it, I couldn't stop my heart from pounding with joy.
The heat of pleasure makes my head melt and I can't think straight.
If my sister is asking for me this passionately, there's nothing wrong with responding to her request.
As such thoughts crossed his mind, his stiff cock throbbed violently as it was licked and sucked by the hot pot, and his shaft swelled with force, pushing back against the intense grip.
"Ahaha, your dick's gotten bigger again! Big brother, you want to make Aya pregnant, right? Okay, come on! Plant your seed in Aya's womb."
"Aya... I, ah, can't take this, ugh, ahhh!!"
The boy's whole body is swept away by a boiling pleasure, and he reflexively lifts his hips.
The timing coincided with Ayane lowering her hips, and the penis collided with the depths of her vagina with such force that it pushed back her uterus, which had fallen back in search of fertilization.
Slurp, squish, squish!!
The glans, slippery with love nectar, pries open the opening of the cervix and buries itself deep into the glans.
The most sensitive, protruding part was hit hard, and the stimulation instantly took away my consciousness.
The sphincter relaxes, and the hot liquid that had been held back at the brink rises up with furious force.
"Ugh, ahh, it's coming, Ayane... I'm, uwah, aaah!"
"It's okay, come! Big brother's semen should be released into Aya's uterus, into your wife's uterus, it's only there to impregnate Aya ♪ Yeeees, I'm cumming, Aya's cumming too, I'm cumming and full of big brother's babies, ahhh, mhmm!"
Splat, splash, splash, splash!!
Along with the loud sounds of ejaculation leaking from the opening of his vagina, the white liquid flows into his beloved sister's womb.
Because her cervix had already been pried open, the hot liquid spurted out with force, hitting the ceiling of the chamber. Feeling her brother's sperm in the deepest part of her precious chamber, Ayane continued to scream in ecstasy with a sloppy, drooling face.
"Ahaha, it's fertilized. I can tell, Aya, I can tell! Big brother's semen is swimming happily inside my stomach and implanting in Aya's egg ♪ You two are a perfect match, so the pregnancy has definitely happened, and you'll become a proper big brother's wife!"
"Ugh, ahh, Ayane... still tight... ugh!!"
Ayane's eyes looked into the distance in ecstasy as she writhed in agony, her vagina tightly squeezing his shaft from the entrance to the back.
Not a single drop is left in the urethra. There is no way to resist the strong will of the vaginal movements, and he simply continues to ejaculate limply.
From the small gap where they joined, semen, stained a pale pink as a sign of her virginity, oozed out, accompanied by lewd gurgling sounds.
(I really did do this with Ayane... as my sister. I was forced to do this...)
A sense of guilt and joy welled up in my chest. Just as I tried to distance myself from him to prevent this from happening, I did something irreparable.
It was too hard to think anymore, so I lay down and closed my eyes.
Let's give ourselves over to the afterglow of this pleasure.
Such a feeling of weakness crossed my mind, but I managed to shake it off with what little rationality I had left.
(No good, that's irresponsible...)
What's happened is what's happened. Anyway, we need to calm down a bit and talk about it.
"Ayane... It's about time you solved this. Then we can talk. That..."
He spoke gently to his sister, who was smiling dreamily and drooping her head, so as not to provoke her.
However...
"...I'm sorry, Onii-chan. Please stay like that for a little while longer."
"Huh, wh, why!? ... Ah..."
As Tomoya asked in surprise, Ayane looked into his face again, so close that their noses were almost touching.
His indigo eyes had narrowed, and contained a madness that sent shivers down his spine.
The boy instinctively understood this and remained silent, but the side-tailed girl gave a small smile and began to speak.
"What happened today made me realise something. I thought there was nothing to worry about because Aya was always by his side, but... there's a demon out there who's leading Onii-chan astray... there's a lot of scum who get in the way of our relationship. So... how about we live just the two of us for a while? Until your heart is filled with Aya from head to toe... until he can't hear the voices of other women. Hehe, it'll be fine, it won't take that long... after all, Aya and Onii-chan have been together since they were little, and we're a couple destined to be together. Ahahahahahahahahahaha♪"
As they gazed at each other, the side-tailed younger sister let out a laugh of delight.
Tomoya was overwhelmed by the force, which sent chills down his spine and made it difficult for him to breathe, and he was unable to stimulate his sister any further, so he could only stare in silence.
They maintain an appropriate distance as siblings. The advice they received from their childhood friend seems to have been long too late.
