The Everyday Scene of the Ordinary Siblings

Prologue

「Onii-chan, Aya wants to enter together !」

As he was sitting on the floor, Nakata Tomoya got startled with her little sister voice, Aya and glanced at her who entered the bathroom.

「Ayane, you know that…… it should be time already for you to enter alone in the bath」

「Mou, why are you saying such mean thing?」

「The problem is not about it being mean or something like that……」

「There shouldn't be any problem. That's because, Aya and Onii-chan are siblings after all 」

The siblings spend time during bath soaking in the water together. This should be a pleasant scene if only they were younger.

We're not at that age after all.

Tomoya glared back at his sister's deep blue eyes that squinted and then flashed a smile at him which just made him shake his head in resignation. She was a head shorter than him and when she was born she was not even as big as a figure of towel being rolled.

Since her arms are placed in front of her body, only the tip of her bowl-shaped b.r.e.a.s.t.s was hidden, they were like beautifully arranged melons with splendid size. Her slender figure is further emphasized with her well-shaped waist and plump thighs.

That, just how long am I going to stare at herー

「A-Anyway, I just want to soak feeling at ease for today……」

Muttering his excuses in a hurry and unable to endure the feeling of embarra.s.sment any longer from staring, Tomoya covered his lower body with a towel and hurriedly s.h.i.+fted his eyes. While doing so, he caught her sister's lower abdomen part pa.s.sed through the corner of his sight. There were little bush of the same light-brown-color as the hair hanging in her left shoulder growing on the part of her mons pubis . It was just enough for the body to increase its charms. No matter how of a family member you are, there should be a limit on how innocently you can expose it like that.

Even so, the person herself didn't felt embarra.s.sed at all and even sat down in front of her brother with her back facing his front. She rested her back on Tomoya's chest without care with her soft and plump long beautiful legs thrown in front.

「Please today as well. Wash Aya's hair which Onii-chan likes a lot♪」

Still in that position she glanced up at him with her cheeks that flushed with cherry-blossom-like hue and smiled brightly at him. Showed with that kind of face from her sister, Tomoya found it unable to refuse her with an earnest and sweet plea thrown at him.

「I get it already. Ayane really is a spoiled child as ever……」

He reached out something hanging on the wall near him with face of resignation.

It was her favorite hair treatment shampoo.

「Ehehee~, thanks Onii-chan」

「Alright, alright. Hey, you're sticking too much. I won't wash it then」

Smiling wryly, Tomoya pushed her sister's shoulder who was rubbing her head like a spoiled kitten on his chest, leaving his body.

「I-It's not like I think your hair is special and felt good or something……」

Rubbing the shampoo in the palm of his hands, he then washed and stroked her long light brown hair clean. Usually he gathers the hair on the left side and turns it to a side-tail making it wavy, smooth and soft like threads of silk. A sweet and sour scent like that of a citrus then wafted around which was different from the scent of the shampoo and soap. It was a very charming scent that gave off the feeling of wanting it to be there all the time.

「Onii-chan……it always makes Aya happy whenever you wash her hair」

「Maa, since Ayane's hair is soft and comfortable to touch」

Since it's too late to take it back, Tomoya honestly resigned to his sister who glanced up again to him and smiled.

「Obviously. Since Onii-chan showered Aya's hair with lots of affections  mon♪」

「Yeah yeah. I got it already」

Tomoya felt embarra.s.sed from Ayane's calm reply and diverted his gaze from her.

It's really astonis.h.i.+ng how she doesn't change from being such a spoiled child.

Tomoya's father married Ayane's mother who both lost their partner just before both children reach the age knowing anything about life. They might just be siblings bound by law but for him, she treated her like a real family connected by blood. He acted as the big brother since he was older and by the time he entered kindergarten his parents were given important position on the company. Since then their parents spent more time working rather than spending more time with their children.

『Mama and Papa are both busy, so look after your sister by yourself!』

Since there is a year difference between his sister and him, he spoiled her a lot which caused Ayane to have childish actions that she straightforwardly show to her brother who took care of her with affections.

『I love Onii-chan!』

With a playful smile, wherever he went to or even when heading to the toilet, his sister would always follow him with a trot  and which made him think that he'll give this cute little girl more love…… and this cycle continued for ten years. She was always beside Tomoya whenever they were together in the house. They also always head together when going to school since both of them studies at the same school and of course, whenever it's during break time she would occasionally show her face to his cla.s.sroom. Since the both of them have no particular hobbies, they just went straight home from school and most of the time, going home together. She would always stick close to him with a special seat just for her except during cla.s.s or during bedtime. Or not, whenever he was already asleep, she would snuck into Tomoya's bed and when he wakes up, she would just say 『I had a scary dream』and just accepts it. Meaning, this guy too, is an extreme sis-con.

Well, I feel happy being wanted though……

His sight often strays down as he wash her the hair edges of his sister's hair on both sides. The sight of twin hills on her chest hidden a while go by her arms casually jiggles whenever he peeked his eyes below Ayane's face who was feeling good and enthusiastic.  It has a well-shaped bowl figure pointing upward, decorated with protruding tip which has a pale-pink color like the petals of cherry blossoms. It was too beautiful to look at that your mind would just s.p.a.ced out for a moment.

「Hnn~, Onii-chan, can you wash not only my hair but also my body?」

Ayane who was still facing in front, as if catching Tomoya for a while now that was glancing at her, mischievously invited him.

「You're too spoiled! Do this much by yourself!! 」

In order to regain his dignity as an older brother, Tomoya hurriedly reply in a panicked voice. What are you getting fl.u.s.tered for from was.h.i.+ng your sister's body, calm down me, calm down! He took the shower hose and washed the bubble foam on Ayane's hair while he desperately tried to calm his mind as he glanced it his lower abdomen that was somehow feeling hot.

His spoiled sister was just sitting between his legs. Just lightly removing the towel covering it, if there appears a change on the thing in between his legs then definitely the tip of his thing would likely touch the valley of her sister's lovely b.u.m. He is really in a serious pinch since his sister might have noticed it already. In order to divert it, he continuously thought about the function that was taught to them just today in cla.s.s as his eyes swam around. However, whenever her hair fluttered, the sweet scent of her hair wafting continually was pleasant making him remember the scene of the incredible breast.

'Cause Ayane is really cute. It's not the cuteness on par with that of an idol but— why the heck are you getting fl.u.s.tered for towards your sister, the worst as an  『Onii-chan』. He kept his eyes shut while drowning himself with self-loath.

「Hnn, Aya will scrub Onii-chan's back then」

Ayane immediately stood up after saying the last word, went and crouched down on her brother's back. She took the body soap with her hands, like she was used to it, she then made bubble foam with her palms and brushed Tomoya starting from his lower arm while his eyes were still shut.

「Hnn, hey Ayane, I can wash by myself……」

「It's alright, it's as thanks. Besides……aren't your shoulders feeling stiff today Onii-chan? Let me also give you a ma.s.sage」

Ayane smoothly rubbed the bubble foams in her hands on his shoulder while smiling on her brother who was holding back.

「The shoulders were stiff…… Hnn ……Fuu」

Tomoya unconsciously held his breath with the sudden simulation when the palm of her hands suddenly touched around his neck. Certainly yesterday, in order to finish the homework report, he was using the computer for quite some time and felt his shoulders had gone stiff but he did not remember mentioning anything to Ayane. He also didn't remember showing her in any manner so it was a mystery how was she able to see through it.

「It looked like your walking posture today was off, Onii-chan. Since the position of your shoulders seems to be lower than 2mm than usual so……I thought that might be it 」

「Heh, so you were even able to notice that」

Tomoya seemed to honestly admire her observational skills like a pro ma.s.seur which can see at a glance.

「Obviously. Since Aya knows everything if it's all about Onii-chan♪ Well then I'll wash your back with my palm whether you like I or not since Onii-chan's skin isn't that tough……」

While Ayane was was.h.i.+ng near his shoulders with gentle brus.h.i.+ng, the palm of her hand left close to the center of his back to pick up the towel that was on the side.

「After this next is below…… or not, then I'll use the towel to brush instead of my hand since it's close to the waist so it's going to be ticklish okay」

She once again rubbed bubbles on the towel and gently washed him as she teasingly cleared her throat. 「Ah, aaah, that's it. You really know it well……」. It really seems like she knows better of his preferences than the person himself. Tomoya left himself in her care as he was admiring her.

「It looks like a little close to the side of your waist is also getting stiff, Onii-chan. It seems like you've been sitting before taking a bath since last week right? Continuing to do it like this should be good for your health」

「Yeah that's right. That being, I should be getting out soon expectedly」

There seems to be nothing different from it at a glance although Ayane tried to look at the side of his waist while brus.h.i.+ng it gently. Well its already fine being seen since we've been taking baths together for a long time anyway…… also……

「As I thought, the muscles of man's body really is amazing. Even though when we were little, it was smooth and squishy which was almost the same as Aya's. Fufuu~ but the Onii-chan right now feels reliable♪」

Ayane was savoring the sensation of her brother as she placed her chins on his shoulder and slipped her hands with bubble foam to the side of his thighs. It seems like for Ayane such things doesn't bother her, instead like it a lot as it was skins.h.i.+p between siblings while the only thing Tomoya can do is give up and blush as he washed her hair a while ago.

It might have just became a habit and nothing to get fl.u.s.tered about if it's just this much every time they took a bath.  Ayane has been like this ever since she was young. Really, she will always be a child. Her body aside, her mind didn't mature at all for the past years. No, if it really did happen I might feel lonely.

When that feelings of unease went into his chest, Ayane stuck her cheeks closer to her gloomy brother's cheeks letting the warmth from it flow to his.

「Naah!! H-Hey Ayane! 」

There was a plump and soft feeling just like a mochi. He suddenly raised his voice and his eyes swam in panic as he never thought that the soft feeling have not changed since then.

「Ehehee~, Onii-chan~, shall I also was your hair?」

「Hnn, y-yeah. Even so you say that, we're already out of shampoo…… 」

His sister would not have stopped from closely sticking to him if he didn't refute so. When he immediately realized it, if not, Tomoya just might have accepted obediently . Since it can't be helped, Ayane might just use the same woman's shampoo that she uses to wash his hair. Or so he thought.

「It's alright since Aya made sure to have bought it yesterday♪」Ayane then went out to the bathroom's door after saying so. She brought something in when she came back and shook the bottle on her hand intending to show it to her brother.

「That………」

Tomoya widened his eyes on impulse upon seeing it. It has a different of a brand from her favorite that she always use. But – .

「Onii-chan, you used to say you wanted to use this shampoo after seeing it's commercial right 」

「Yeah, you sure did remember it huh」

He made sure to remember and buy it after the next time after their currently shampoo is emptied.

「I told you right. Whateve~r it is, Aya knows everything about Onii-chan」

「T-That really true huh. No, as expected you know too much……」

「Does Onii-chan dislike it? Are there other things that Aya……doesn't know? 」

Tomoya was unable to hide his surprise and unintentionally cleared his throat. Tomoya was surprised and let out a weird shriek when Ayane let out a chilly voice devoid of emotions. Her expression from before made a sudden change into something with indescribable emotion just like that of a Noh mask, her healthy cheeks that flushed with the color of cherry blossoms just a while ago was replaced with a dark shadow.

「Aya thinks about things like as siblings we get along well together to know much about each other 」

Something like a snapping sound echoed in the bathroom matching Aya's displeased voice. Suddenly seeing the brand new bottle that her whitefish-like pretty fingers were gripping being miserably squashed. Tomoya saying something he shouldn't have to his sister, panicky started making excuses upon seeing it.

「H-Hey, don't get mad. It's only because I was startled by the pleasant memories. That, thanks for taking your time to buy it for me」

「Then…… it's not because you dislike it? 」

「There's no way I don't like it.  Ayane is really thoughtful, you'll definitely become a splendid wife in the future 」

Tomoya declared with a smile to his sister to who was asking him with upturned eyes. She really do have mood swings, not that it bothers ne though.

If you mention about being aware of Ayane snapping and her mood getting worse then there are instances that it happens a lot. Giving a follow up immediately with a smile then she'll just turn back to normal so he doesn't really mind it that much.

「A splendid wife…… does Onii-chan really think so? 」

Even now, she was smiling brightly with her cheeks flushed red that her dark expression just a while ago seems to be a lie.

「I haven't told any lie to Ayane even once 」

「Yeah, that's right ne. Fufuu~ thanks, Onii-chan♪」

Ayane, rubbed her nose against his neck like a puppy as she replied with a lively tone.

「H-Hey, you're sticking too much…… Hnn 」

The sweet scent wafting from her washed light-brown hair which he can't help and be conscious about it which sends currents run through his spine remembering that moment. Besides it's Ayane that is pus.h.i.+ng her body forward making him feel that bulging chest on his back. As expected it's not that her chest was being pushed into his back strongly but it was smoother than the other areas caressing it directly to the moist skin. For a boy who's originally ticklish and sensitive which made him feel like his waist is going to float. Sometimes feeling a little stiff and smooth small bulge rubbing against his back. Thinking that there was no doubt that it was actually that cherry blossom-colored protruding tip that he accidentally saw a while ago made the thing on his lower abdomen twitched and throbbed which he desperately suppressed from getting excited.

「Hnn~ the washed Onii-chan's smell. Although it's little weak but the soap's scent smells good in its own way…… haa~ hafuu~ hnn♪」

Either realizing it or not or making sure of it at a side glance, she squinted her eyes and her face was having an ecstatic expression as she intentionally moved her lips close to the nape of his neck. For some years now she strangely had the urges to sniff her brother like she had some kind of smell fetish. It can't be really said that it's a good thing but seeing that blissful face would make you hesitate to reprimand her or tell her to stop.

I-I'm…… really at my limit though! !

Screaming internally, it seems that he won't be able to endure it any longer with the sensibly stiff grain-like pulp sc.r.a.ping on his back and giving him a tickling sensation. He was having a reaction that he shouldn't show in front of his sister.

「Hurry up and finish was.h.i.+ng my hair Ayane, it'll soon get cold if you leisurely take your time, also I want to try out sensation if being washed with that shampoo that you even bothered out to buy for me too」

「Yeah, that's right. Aya will be sad if ever Onii-chan caught a cold. I'll make sure to nurse you though, with all I've got of course, so there's nothing to worry about……hnnnn……」

Ayane was a little bit hesitant but she properly parted with his body obediently.

「Well then Onii-chan, keep your eyes close so it won't get in okay」

「I get it already. I leave it to you」

Tomoya closes his eyes while reminiscing something while smiling wryly, the time when they were young, he would always try tell her sweet lines whenever he washes her hair.

Yare yare, I need to be careful on this sibling skins.h.i.+p too for another year once more.

Tomoya heaved a deep sigh from his chest as he was basking himself from the comfort of being caressed by the fingers that were was.h.i.+ng his head.

「Fwuuaahh~…………」

Breathing it all out together with the tiredness he acc.u.mulated for the day as stretched his body soaked on the bathtub up to his shoulders. Ayane who was together with him a while ago went out first.  The bathtub at their house wasn't big enough for two people to soak in together. Thus Tomoya relaxed himself alone soaking his whole body and warming up which his sister who knows everything about her brother preferred that.

「Even so…… I wonder if this is okay」

Tilting his head as he scratched his wet hair which Ayane washed gently with her fingers.  She was spoiled and never changing as ever, but it even escalated more when their parents went overseas for business trip about three months ago. A week ago, it was just for once but recently she's been entering the bath together every day.

「She must have been lonely…… without Dad and step Mom huh」

On the day before their departure he remembered her smiling while seeing them off saying, 『You don't need to worry about us at all right here. Aya is with Onii-chan so the two of you can just take it easy even for years! 』. Was that an act for the sake of letting the both of them travel without worries. Thinking about how her sister have felt lonely, we wanted to reliably support her.

However——

「Since I'm also a man…… haaah, you can't, you mustn't!」

Calming himself down, his sister's figure being burned on the corner of his mind appeared, recalling the sweet and sour scent wafting from her hair near him and the rich sensation of her t.i.ts tickling his back.

Now that he doesn't need to hold back any longer, together with the near numbing feeling and heat rising on his lower abdomen, with vigor his thing rose and erected furiously in the bathtub.

Feeling l.u.s.t towards your own sister…… the worst.

Ayane is only spoiled towards her own brother. That's the most thing he must absolutely avoid from betraying.

「I should say to reduce this skins.h.i.+p a little bit huh…… but if I say that to that Ayane, she'll make a really depressed face. Snap out of it, I'll get depressed too……」

He'll somehow eventually reached into a conclusion and maintain their usual relations.h.i.+p he thought as he held his head in struggle. You'll just be okay as long as you firmly stay as 『Onii-chan』. You only need to think of that. His erection eventually died out as he reached into a determined resolve.

「Well then, I should already get up」

He saw Ayane's silhouette from the back of the door as he got up from the bathtub. He remembered her saying that she'll do the laundry after getting out from the bath. He felt a little embarra.s.sed to go out now but it would be weird if he wouldn't since the both of them were together just a while ago. Tomoya brood over it for a while before getting out after wrapping himself with a towel tightly up to his waist.

「I'm getting out Ayane~, thanks for always doing the laun…dry……」

As expected, Ayane was standing in front of the was.h.i.+ng machine that was placed in the dress area when he opened the door. The long brown hair that Tomoya gently washed is tied in side-tails with her favorite pink tie and was resting on her left shoulder, on her head was a headband with a ribbon that's placed on the right side opposite of her hair position. She wore a one-piece dress with a lot of frills colored to match her ambiance. Her clothes are lovely dresses like that as her favorite. Though Tomoya thought that she was a little more pa.s.sionate on doing her room, and attentively said 『I can't let Onii-chan in to such messy room』.

There was nothing in particular that he wanted to say but, the problem is— what reaction would the Onii-chan make towards her sister face looking blissful.

「Those…… are my clothes right……」

「Hnnfuuuu, haah, fwuaaaah, Onii-chan's scent……such thick smell~」

Before taking a bath, he threw all the school uniform that he wore in the laundry basket. Ayane was holding it with both hands as she sniffed it making wild sniffing noise.

「More than the s.h.i.+rt, this one smells better. Especially……here……」

Somehow making a loud noise clearing her throat, rather than the s.h.i.+rt, she pulled the trousers of his uniform towards her nose. She was sniffing around the knee area of the cloth, while Tomoya was just silently watching the event unfold, as expected he can't just keep silent as her sniffing was getting closer to the fastened crotch area of the trousers.

「What the heck are you doing Ayane!」

「Hnn, Onii-chan?」

The sister who raised her face up was showing an expression of not understanding why her brother looked somewhat angry as he reprimanded her flicking her head lightly.

「Hey, what are you doing smelling off the laundry」

Though it was already embarra.s.sing that she was sniffing him directly on his while she was behind him when they were in the bathroom but this and that are different matters making him feel like something crawl on his skin sending him s.h.i.+vers. However, even though Tomoya has already asked in such manner, Ayane just tilted her head in wonder.

「Since there is a need to put it in to wash it so I'm just making sure of it you know? Also, I'll be able to check on Onii-chan's physical condition this way too」

「C-Checking with the smell too? 」

It's been her doing all the laundry for the past years saying to leave everything to her. Even though it was to examine if it's dirty or not but is there really that kind of way to do it.

Well, there might really that kind of……way right?

He can't clear up his doubt but for the time being he decided to persuade himself. Once again Ayane buried her face on the trousers making him astonished.

「……………Such smell 」

「I-Is that so? Just that, is there no other way…… 」

「This isn't Onii-chan's scent……」

Without listening to Tomoya's voice, the sister with side-tail harshly searched the pocket of his trousers and from there she took out a white handkerchief with lace.

「This, isn't Onii-chan's right……」

「Huh? …… Ah!! 」

He suddenly remembered after seeing it on Ayane's hand.

「That's right, I totally forgot about it! That is…… 」

「It's Saa-chan's right. There's no doubt……this milk-like stench 」

Just before Tomoya was able to talk, Ayane's eyebrows knitted after she brought the handkerchief on the tip of her nose.

「Y-Yeah. You really have a good nose……」

He just replied with a nod being astonished for knowing it just with the smell. Just as Ayane said, it was borrowed from Hos.h.i.+ Sayaka, which is also the girl called 『Saa-chan』that is Tomoya's childhood friend whom he had known for a long time now and also lives next to them and been neighbors for the last ten years.

「Why is Saa-chan's handkerchief on Onii-chan's pants?」

「No, that is……」

「Are the both of you hiding something from Aya? That……makes me lonely」

Without listening to the young man's explanations, Ayane's deep-blue eyes turned gray as she scornfully glared at the handkerchief she was holding on her right hand. Her voice turned chilly as if her sweet tone a while ago were just lies. Tomoya inadvertently took a step backwards as he was taken aback by an unknown pressure.

「No way… Did you do something you can't tell Aya? ……」

「No no no! You know, today I forgot to bring my own handkerchief. She just let me borrowed one since she said he had an extra one」

「I see. …… yeah, Saa-chan likely would do that」

「Yeah. That girl is surprisingly attentive to such things right」

Since he was a man, although it should've been alright to wipe on his pants without trouble, even so it didn't deceive his childhood friend and didn't allow it so she pushed the handkerchief and lent it to him.

「It's not like that you know…… she just want to show-off in front of Onii-chan」

「Hmmm, did you say something? That being said, I need to return that tomorrow……」

Head down, as his sister was muttering in a low voice which he can't hear, Tomoya tried to take the handkerchief from her hand. But Ayane dodged his hand, refusing to let him take it and hid it behind her.

「You can't you know! We have to properly wash it before returning iitt !! 」

「Eeh~ Yeah…… I see, that's right huh」

Ayane who was frantically tiptoeing looking at him, Tomoya noticed and realized. As his sister has said, it should be manners to wash something borrowed before returning it.

「It need to be properly washed and completely remove Onii-chan's scent. There's should be no one other than Aya smelling Onii-chan's scent. I won't allow it……」

「Errm, then it should be okay to leave it to Ayane right? 」

Ayane was squelching the handkerchief tightly and muttering again something with a voice that can't be heard. Somehow there was a strange mood, doing the laundry together should be fine but he decided to leave it to her.

「Yeah, leave it to Aya. I'll wash it that it'll look brand new!」

「O-Okay……」

Ayane kept on grasping the handkerchief while grinning and smiling. Tomoya felt something p.r.i.c.kling his chest with words like it meant something else.

「Well then…… this is my work payment okay♪」

Once more his sister with side-tail tiptoed forward to him and stuck close to his face. Her dazzling pink-rose petal-like lips touched the young man's cheek making a cute kissing sound. He felt hot again even though he just got out from bath and the warmth has yet to fade.

Ayane flashed  blissful smile certainly towards Tomoya who had his eyed open wide because of the sudden occurrence.

「Eheheh~ as I thought, directly doing it rather than on the clothes is better. Onii-chan's scent」

「No, that isn't the problem, just now, that kiss……」

「Can I do it again Onii-chan? A kiss reward for Aya! ! 」

He just once more offered his right cheek in resignation to his sister who was in good mood. This kind of treatment of kissing in repet.i.tion was his spoiled sister's favorite.

「You're really……」

『Just as spoiled as ever huh』, those words that Tomoya stopped from uttering and just swallowed it. After all, somehow, he himself, also like to spoiled her a lot.

Well…… it a good thing, as siblings being close and messing with each other……

While convincing himself, the sister conveyed her feelings to her brother as she pushed her soft and gentle lips to his cheeks.
