Chapter 1-Shiraishi Toru (A conversation with my biological younger sister Misuzu)



Since the time of my parents funeral who had passed away due to an accident a few years ago, my beautiful younger sister who didn`t come near the house suddenly came to visit me and I became speechless listening to her reason.


“I want Oniichan to look after my daughter, Mai…”



My younger sister got pregnant during her first year of high school. Dropping out of high school because her  boyfriend had gotten her pregnant, resulting in a shotgun marriage. Although she gave birth to her daughter Mai at the age of 17, in the following year they got a divorce, saying “living together is impossible”. Because my parents had disinheritance her, it was not possible for her to return home, she survived by repeatedly separating and attaching herself with several men, I was then made to listen how this continued for 10 years.

My memory as it concerns my younger sister had remained as “a JK bitch”, but I realised that my blood related sister that was 28 years old who was sitting around the meeting table in the living room was in a difficult situation. Therefore, as it relates to her elementary daughter, if apart from the blood relation called uncle and niece, it can be said that she is a completely unrelated person whom I do not even need to meet.

That being the case, there was no reason to bow in agreement and when I told my sister, she groan and wrinkled up her brow.


“You, aren’t you aware of what you`re saying is absurd? I am a 30 year old bachelor, after this can a man plan to look for a wife? Don’t you think this will completely end if I shoulder your child.”

“I understand it’s absurd but, no matter what,I will be in trouble if you don’t take Mai.”


My younger sister who sits down facing me on the other side of the low table in the living room, leans forward and repeats word of wishes again.

A fair slender face with a pair of almond shape double eyelid, a straight nose with a somewhat fat lip, with that appearance my younger sister who possesses enough of that kind of beauty could find any man to rely on while being a parent. Then, with her neck tilting a little and shaking her orange beige shoulder length hair, this action that was being displays made me frown, I had the feeling she is quite accustomed to seducing men.

For the past few years, having known nothing but women from brothels, my gaze had fell from my sister’s face and by only stealing a glance at her breast in that dress that was wide open, I could feel my groin bulge naturally.


“After all if I have your daughter I won’t be able to remarry, is such a reason not good enough?”


I said somewhat cranky while holding in my lust for my blood related younger sister, I then rested my chin on my hand that was on top of the low table, throwing my gaze in a different direction.

She temporarily stopped talking but, while staring in my direction she pouted her lips and made a small nod.


“……Alright. There is a person who wants to get married but, he says it’s impossible if they’re taking one`s child along.”

“Hey, wait just a minute, now seriously what’s the real reason!”


I smacked my palm on the table once while raising my voice. My sister`s body flips up together with that sound, then turning her face away she became silent as if she was defeated. I looked at the face of my sister with her brow wrinkled up while waiting until her voice came forth.


“…..There’s no other person I can rely on”

“Even if I help you there will be nothing but demerits for me. Anyways, I guess the child support will also come from me? Or are you saying you will get it out of the man who will become your new husband?”



Looking at my sister who became silent again, I dropped a big sigh.


“Suddenly coming and just expecting my goodwill is just impossible. Besides, you’re attitude isn’t that of a person who is asking for a favour? The child support money that will be amassed must be returned, you must be willing to do anything, by the way is this how you normally request for something?”

“….Even if you say such a thing, that is something that I cannot promise to do…..”


Glaring at my younger sister who was mumbling, made me in the end stand up and grasped her upper arm.


“Then go home!  Get out right now!”

“Just like that! Wait! Oniichan! Please, because.. I will do anything…help me!”

“Can I even believe such a thing?!”


My strong fingers dug into my younger sister`s upper arm who was trying not to get up while dragging her on top of the tatami, I dragged her all the way up to the passageway.

At that time the hem of my younger sister`s short dress became disordered due to being throw down resulting in her white thigh almost becoming exposed. Looking down from above the scene of her breast wide open made me become stiff, the deep cleavage and black cup bra with a twisted shoulder strap was thoroughly reflected. Then, looking up at me who was looking down on her, my younger sister`s floating tears dropped on my hand and the poor begging stopped.


“I am serious…. because I will do anything! Hey, please….”

“Then become my slave? If you’re doing anything, then are you willing to become my slave?”



My younger sister who sat in the hallway nodded while looking at me with upturned eyes. I snorted in seemly displeasure releasing her upper arm that was being grasped until now. On her hand a finger mark remained, I then told my younger sister who was already rubbing the other hand.


“You must prove that those words weren’t just lip service”

“W-What should I do ?”

“Think about it yourself!”

“Ahem…..I don’t know!”


I looked down on my younger sister who was just sitting there quite daunting and she bursted out crying, covering her face.

I lived with my younger sister in this house until she had graduated from junior high, when she went into upper grade in elementary school she started to glare at her older brother like a disgusting object and quite plainly avoided me.

At that time I asked her for the reason why she hated me.

Her reply was “You look disgusting, your atmosphere is detestable, if you’re my brother I don’t want other people to know” because of those words, since then, anytime I came in contact with my younger sister I acted like a stranger.

Therefore, looking at my younger sister who was crying the said feeling of pity and so on were not the things that came gushing forth. Instead, while remembering those times that were uncomfortable, it can be said that right now am enjoying the current situation.


“If it’s a slave, it would lick my foot?”


When my younger sister heard my words the hands covering her face was removed while wiping away her teary eyes, she looked this way with upturned eyes.

My eyes narrowed deliberately not giving out any emotion with folded arms, silence waiting.

Then my younger sister corrected her posture at my foot, slowly bowing, I was then able to feel her tongue press against my right foot, I accidentally swallowed my saliva quietly. My sensitive dick flipped up inside of my pants.


“Not only the top of my foot, the toes must also be licked”



I leaned against the hallway wall so I could raise my right foot that was being licked. My younger sister raised her head in pursue of it with her mouth, and the face of my younger sister licking my right foot gradually became exposed.

I thrust my toe into her opened mouth to have it sucked instead of being licked.

While doing nothing, I looked at my younger sister whose tongue crawled between my toes, staring into my younger sister`s eyes full of anguish that would sometimes rise looking this way. Then, at that moment by continuously raising my foot it  had become painful, causing me to pull my toe from my sister`s mouth.


“Take off your clothes”



Not complying with my words, I grasped my younger sister hair who was hanging her head in shame, forcefully pointing her face upwards.



“If I say undress, then immediately get undressed!”


Her face was brought forward and after declaring at point blank range where my companion can feel my breath, I released her hair that was being held.

On the spot, my younger sister had lowered the zip at the back of her one piece dress, letting the cloth slide down from her shoulder. Still sitting down the dress was pulled off and her figure became only panties and a black bra.

Later on, I learned that my younger sister’s breast that was shaking while being supported by a black bra was a 94 cm G-cup. Sitting cross legged, her well fleshed ass connected by a deep narrow waist was reflected.


“Take everything off”

“Oniichan……..we are brother and sister?”


My younger sister who was only wearing her underwear and was slightly covering her breast with both hands while knitting her brow, had said that looking up this way. In contrast, I clicked my tongue and answered by grabbing her hair.


“It hurtss!”

“Tsk! What happened to that? From before, I haven’t thought of you as my younger sister! If you are a slave, you exist to take care of your master`s sexual needs!”


While pulling my younger sister`s face between my legs with one of hand, I pulled down my pants zipper with the other.

Then, pushing aside my underwear, I took out my swollen dick from inside and then thrusted out my spear head before my younger sister`s eye.

My meat rod was forced down by grasping the base with one hand, clearly showing the precum hanging down from the tip of the glans overhanging the gills. On the surface of the grasped rod, the bulging veins were visible, and as for the view of my younger sister, it’s expected that the twitching frenulum should have been reflected.

The last time my younger sister had seen my penis should had around lower grade of elementary school but that event was so long ago that it should have been forgotten. And now, with her adult older brother’s thing in front of her, the expression of my younger sister who was looking this way was perplexed, and it had excited me together with the thought of immorality. (TN: I think that was when she started hating him)



“Open your mouth.

“Suck your big brother`s cock!”


I pushed my glans parting my younger sister`s wet lips who was trying to turn her face away with her eyes tightly shut. Then, I grasped her head with one hand turning that face that was trying to turn away forward, pushing my hard dick into my younger sister’s mouth that began to open in resignation.


“Ugh!Nnn! Hnnn!”


Once my dick was inside her mouth she completely gave up on any thoughts of resisting. Kneeling before me who had a daunting pose, she started to service me with her mouth while grasping the base of the meat rod with one hand.

Because of taking me in her mouth, it had caused her lips to open wide and sometimes she would look up with an upturned gaze this way. The beautiful woman whose tongue entangles and sucks my dick while tilting her head left and right together with the way her eyebrows came together was damn sexy, with the fact that she was also my blood related younger sister it further fuelled my arousal.


“As expected you’re used to this. Taking off your bra while doing a fellatio. Your mouth should never separate from my cock.”


Swallowing my disordered breath, I ordered my younger sister to continue the fellatio. Then, she did it without resisting, moving both of her hands towards her back to remove the bra strap.

The black bra became loose and from the bra cup her white breast slipped out, making her breast shake while matching the movement of her fellatio. At the centre of her areola was an pointed reddish brown nipple, I discovered that her nipple had began to sharpen somewhat, so with the nipples being exposed I decided to knead them.

Then, by grasping my younger sister’s head and shaking it back and forth many times so as to continue the fellatio I had become victorious in resting in her mouth as it is.




My younger sister who pulled down the shoulder strap had discarded the bra in succession, increasing the stroking of my penis with her mouth while making wet noise. With one hand grasping the base of my rod and stroking it there, my spear head had gotten wet due to her tongue and wet mouth. With some of my younger sister`s short beige hair covering her face, she had checked on me who was close to cumming with upturned eyes.




Then, before long I had reached my limit, drawing my younger sister`s head towards my groin with both hands.

My wet meat rod that was wrapped was crammed into the gap of her lips and at that moment I felt my swollen glans blast into the innermost part of my younger sister`s mouth, resulting in her groaning like in pain.




At that moment I ejaculated. My meat rod jumped up numerous times inside of her wet mouth, and my semen had run through the urethra like hitting a pulse, gusting out its load aimed at the throat of my blood related younger sister.

That pleasure had made my whole body shiver, after stuffing the cloudy bodily fluids in my younger sister`s mouth who was only in her one piece black underwear, I told her while swallowing a rough long breath.



“Nnn, nn…..*gulp*…”


Two time, Three times, I made sure my younger sister swallowed my semen sounded out in her throat while my penis was still in her mouth. I unintentionally leaked out a moan at the movement of her tongue when it swallowed the gathered semen inside of her mouth while tightly closing her eyes, bringing her eyebrows together.

Then, I started to pull out my dick that had spit out my desire from her mouth the moment I felt that my younger sister finished swallowing everything.


“Nnn, hha, haa, haa….”


I raised my younger sister`s face by grasping her chin and wiped her wet mouth with the back of my hand. Then, bringing my partners face closer, I said in a low voice.


“You should understand now, after this is actual the sexual performance.Come”


I grasped my younger sister`s arm for support then I brought her to the room I normally sleep in alone.
