[LN] Ore no Imouto ga Saikou no Okazu datta - Volume 1 - Chapter 4

 Chapter 4 - The Neat And Clean Girl Is Erotic And Very Cute


 Ever since I made my little sister my material masturbation, my thoughts about women have changed. It's just that I don't have to lust after other girls because I'm devoting my sexual desires to my little sister. Even if I don't intend to show my attitude, it seems like it's transmitted to girls.

 This is a good trend. Girls seem to get offended just by feeling affection from a guy they don't seem to like, and an unpopular otaku like me creates an awkward atmosphere just by talking to him.

「Ya-ho, Sotomichi-kun, let's hand out social posters」

 A bundle of papers was placed on both my arms. Niheh, the most popular girl in school who smiled with bright white teeth was my partner in charge today. I know how cute she is, and usually entrust the work she asks for to others. She's so cute that no matter how selfish she is, her anger doesn't rise, and I feel the cruelty of reality. I'm sure she'll be loved by everyone from now on.

 Kanade Yamamoto. A perfect model student with talent and interspersed with a very alluring beauty, her beauty attracts both men and women. My heart, which should have been with her on the day's assignment, forgot what had happened. In front of Yamamoto-san, who excelled in beauty modeling, it seemed like I had lost my libido for anything other than my little sister.

「I wonder if I can say it was a reply print by handing out 20 sheets」

 On the way back from home, in slow time, while our classmates continued to talk nonsense while sitting at their desks, we, the daily duty staff, were distributing a large number of midterm exam preparation printouts that our homeroom teachers had given us.

「So yes. Most of my testing is from the printed sheets, and I'm pretty thorough, don't you think?」

  Yamamoto-san folded her hands behind her back and followed me around. She had just handed out the math formula collection sheets one by one, and her work wasn't done yet. I'm fine. Doesn't she know that if she doesn't do her work, she's wasting time and spending more time chatting with me?

「 Yamamoto-san can learn easily.」

「This is motivation. If I tell you that I'll let you touch my breasts if you get a perfect score, Sotomichi-kun will remember about 20 of them, right?」

「That... I'm starting to feel capable of catching up」

 Tits? I wonder if Miyu will let me touch her breasts if I bring her a fully marked answer sheet. Miyu's breasts are big, and I can ejaculate just by rubbing them. And so on, while delusions that didn't exist in my mind grew, I split the trail bit by bit. I don't know, this will swell to unnecessary places.

「Sotomichi-kun」

 Yamamoto-san's voice suddenly became closer to my ear. When someone speaks sweetly in my ear, my heart will reflexively pound. If you do this, a man who has no experience with women will instantly fall. What would happen if I didn't have any female stirrings?

「Do you not like girls, other than 2D?」

「What? No, no, I like them. Why?」

「Because you rarely see me, I don't feel embarrassed」

 Yamamoto-san put her hand on her cheek and tilted her head. Does this woman think that all the men in the world are aware of her? And I have doubts about the mysterious high self-esteem. Is it worth considering Yamamoto-san's level of beauty? Even if I just walked around the city, I wouldn't be able to stop staring at her around her.

 When I thought about it, I realized that I was thinking about my little sister without even glancing at Yamamoto-san's blouse, which was so puffy that it looked like it was about to burst. I couldn't help but think that I wasn't interested in women other than my sister.

「Do you like girls with small breasts?」

「No」

「I understand」

 I reflexively affirmed. And, what's with that sly face?

「I don't like it when girls use the word breast in class」

 Since you're a pretty girl, I want you to try to keep your speech more polite.

「Yes. I'll be careful」

  Yamamoto-san clenched her mouth and smiled softly.

 Please help me to distribute the molds.

「Sotomichi, you talk too much with Yamamoto-san!」

 It was my friend Takanami shouting in the empty classroom after school. He was in the tennis club and her hobby was playing eroge games. A virgin like me.

「That's right. You chatted for too long.」

 My other friend, Suzuhara, synchronized as he quickly raised her glasses. He is a geeky nerd who loves eroge at Go Home Club. He's a virgin like me and has no experience with women at all.

The three of us, connected through our hobbies, have been friends since junior high school. It was a bit troublesome to make a couple with three people, but Takanami's communication skills were quite high, so somehow I was able to survive with this group.

「I didn't do anything」

 I can't deny that I have a sense of superiority, but I actually didn't do anything. I knew that I would stand out if it was like this, so I tried not to talk to her as much as possible. This is because Yamamoto-san is very friendly. Suzuhara in particular was in a bad mood all day. Are you so dissatisfied that I was paired with Yamamoto-san?

「Moreover, it was only these days that I was detained for daily duty. What's that? Isn't Sotomichi only interested in 2D? Keep smiling」

 If Suzuhara makes a frown on the bridge of her nose, I will curse her. I want to deny it, but I can't argue because my little sister has deviated from the 2D path.

 I'm currently waiting for Yamamoto-san to return from the staff room. After receiving urgent orders from the homeroom teacher, Yamamoto-san and I were supposed to do work such as guarding the tables for the reading session for elementary school students to be held in the multi-purpose room.

「Well, you shouldn't be too angry, right?」

 Takanami scolded Suzuhara with a pose with both hands above her head. Exactly so. We went to the club activities.

「Let me tell you, Yamamoto-san is friendly with everyone. Don't misunderstand」

 Suzuhara was frustrated and spat out meaningful words. Where did that 2D story go? I know you're jealous because I'm with Yamamoto-san. If I didn't have a younger sister and Suzuhara was on good terms with Yamamoto-san, I would be just as upset.

「Sorry for keeping you waiting」

 The person we're talking about straddled the sash of the classroom door cheerfully. His supple chest popped out as he landed on his feet. Thinking that that dazzling smile was directed at me just now, I couldn't hide my happiness.

「So, there's maintenance in the multi-purpose room. The volunteer said we can go home on time」

Then, the news about the end-of-day shift suddenly came. It's not really sad, but it's annoying that Suzuhara is blatantly widening her nostrils. Since I'll be home on time, I've entrusted my sister to take care of the food.

「Then, Yamamoto-san. Shall we go home?」

 Suzuhara walked out with her bag and urged him to go home. It's okay. No matter how I think about it, it's not work that students should be doing. That stubborn homeroom teacher must have been warned by other teachers. Yamamoto-san and I weren't alone on our way home, so I decided to go home together.

「Well, then, let's all four of us go home!」

 Takanami was the first to follow Suzuhara. Although she has the ability to win the prefectural tournament, she is a broken person because she has no motivation. I don't like that kind of place either.

「Eh, can we all go home together? Hooray! go go go」

 Yamamoto-san jumped slightly with an air of excitement and headed towards the hallway. Suzuhara tried to say something, but she seemed to be overwhelmed by her desire not to offend Yamamoto-san, so she chased after him, leaving only her tongue clicking. Like today's harvest, Yamamoto-san turned out to be the one who could destroy our circle.

「I'm back」

 Arriving home, I was tired of Suzuhara's reaction to Yamamoto-san, who always wanted to be sticky, so I stared blankly at the shoe holder at the entrance.

 The scene was somehow different from usual. I wasn't sure what the difference was. Without worrying about it, I took a sip of tea in the living room and climbed the stairs to return to my room. Then I heard the sound of a door opening from the back of the hallway, and then came the sound of footsteps approaching.

「Miyu, I'm home. Now, I have no plans for today」

 I climbed the stairs while praising myself that I could say goodbye on my way home.

「Oh, welcome back. Did I disturb you」

 The person who bowed her head to me was a girl different from Miyu.

「Oh, oh, oh hello」

 When I met a girl that I didn't know about, I panicked a little.

What is this beauty? Judging from her physique, she should be the same age as Miyu, but she was so sexy. The thickness of her lips and tear sacs were beautifully defined, and it was so shocking that it almost changed my worldview that there were people who looked so good in this shallow expression of life like a doll.

「Um..... is it okay if I pass behind you......?」

 While fidgeting, the girl glanced at the restroom behind me.

「It's rude for me to keep standing like this.」

 I took a step to the side and looked at the angel passing in front of me with my eyes. It makes me horny to think that even a pretty girl pees in the bathroom. On the way home, Yamamoto-san's breasts were flickering at the end of my sight, so strangely I got excited.

 Type-wise, does she look more like Miyu than Yamamoto-san? But still, I don't think that I'm a lolicon. She's petite and has a look that suits her in a rough Loli style, but that's not because I like her very much.

 Her behavior when she bowed her head and greeted me. She casually brushed her long hair and let it flow behind her, keeping a distance in her heart without looking at him or looking away. That kind of thing suited my sensibilities perfectly. She was completely innocent and beautiful. I even called her an angel.

(This is not good... I really want to masturbation...)

 Even at this moment, the girl sitting on the toilet seat takes off her panties and exposes parts that no one else can see. While feeling the pleasant sensation of something warm coming out of your bladder, you will release the lemon-colored liquid, clean it with a washlet, and then wipe the place... I wasn't familiar with female sexual awakening, but I wonder if she felt it at that age. As she was wiping her hands, she happened to touch her sensitive area, and from there she fell into the depths of her obscenity...

 This is not good, I have an erection. I'll go back to my room without thinking about anything stupid. I told myself that it's not good to turn a foreign girl into masturbation material, and put my hand on the door knob.

 Right after that, the door made a clicking sound even though it wasn't turned.

 It could be heard from Miyu's room next door.

「───Mi, Miyu!, why are you like that? ......!?」

 Miyu was in the hallway wearing only underwear. Her hair was loosely tied up and tied into two knots. The moment I saw that figure, my dick grew bigger.

「Onii-chan......」

 Miyu glared at my crotch. She seemed angry that I was having an erection. However, the reason is completely different from what I imagined.

「I want to talk to you for a while. Let's go into the room.」

 Miyu approached me, wearing only her underwear, and pushed me into the room.

「Is it okay if I don't change my clothes?」

「I should have warned you before that. Onii-chan will probably do it herself.」

 Inside the room, I faced Miyu, who was weighed down by her heavy breasts in a cute pale pink bra. As usual, Miyu's eyes are staring at my erect crotch.

「You were already like that before you saw me, right? You're thinking of something naughty, right?」

「You were thinking about my friend going to the bathroom, Haruka. Is it like that?」

「That's bad. Because I will never allow you to make Haruka your masturbation material. If you're horny, get out here now」

「Now? Even though your friend is here?」

「Haruka will be back soon. And since I'm going to be like this, you can start cumming soon?」

 Miyu knelt on the floor and shook her face lightly from side to side, her soft twintails swaying.

「Yes, well... of course... I can put it out, but...」

 I can easily ejaculate without rubbing for several minutes while worshiping the cleavage wearing only underwear and squeezing my dick in front of my own sister with cute hair and makeup.

「You know. Since I've come this far. You can't have Haruka as your material masturbation for the rest of your life. Then I will seriously keep my distance from Onii-chan」

 Seeing Miyu's unprecedented fear, I felt that she was ready to break off relations with me if necessary.

「I will never do that. So let me ask you one thing. Can I insert just the tip into your cleavage?」

「Yes? I want to rub your dick in the center of my breasts?」

 Miyu showed me how her soft breasts were deformed as she lifted her large bra-molded breasts. Her reaction was unexpectedly positive.

「Yes, that's it!!! I-I want to!!!」

「Well, I won't. What does Onii-chan want from her little sister's body?」

 Damn, let me give you hope. If this happens, I'll make you into my masturbation material.

「Then do it there. ——Haruka, sorry. Since it's an emergency. Go home today」

 When Miyu heard the sound of running water in the toilet stop, she stood up, opened the door narrowly so that I couldn't see her inside the room, and started talking to Haruka. I also want to chat with her even if it's just for a moment.

「Don't you hate it when your Onii-chan hears your voice?」

 From the hallway, I heard a voice with a sweet heart. What is she talking about

「I won't forgive you if Haruka says more than that.」

「I wish I could wear some clothes. Should I borrow yours before for free?」

「I don't need that. hurry up and go home」

 Miyu treated Haruka like she was talking to me and kicked her out of the house. I saw from the window that Haruka had returned home, and Miyu was sitting on her knees in front of my dick again.

「Why don't you start by yourself」

I was scolded for not shaking. How can I shake in such a mess?

「What are you doing with Haruka-chan? Dressed like that, what about her clothes?」

「I can't say, and it's forbidden to look for it. Ejaculating without saying four or five」

「Oh, oh, I get it....」

 I was scolded by MIYU and grasped my already erect dick reluctantly. I rubbed potassium with her skin, and masturbation, which usually takes no more than a few minutes, this did not give me the feeling of ejaculation at all. Although I saw Miyu in her underwear dressing up like a loli. Haruka's face wouldn't escape from inside my head.

「Can you give me some time? I'll definitely let it go with someone other than Haruka-chan」

「No. That can't be believed. Get ejaculated here even if it's stubborn」

 Miyu had a sullen face and was ready to fight back. She was protecting Haruka to such an extent.

「Hmm....enough. Onii-chan, let go of your hand」

「e? oh yeah」

 I stopped masturbating, which was like rubbing rubber, and removed my hand from my dick which was covered in heat from friction. A different body heat wraps around my cock shaft, providing stimulation back and forth with an unfamiliar hand. Miyu's small hand rubbed my hand.

「Ah, ah...!! Miyu!?......!!」

「You will cum with this. I'm going to drink semen as usual, so let me know when you're going to cum. If you dirty my underwear, I will destroy you」.

「Wow, I understand, I understand... Uh, oh!!!」

For the first time, I experienced the feeling of being able to hold something other than my own palm. Normally, I'm four fingers down in reverse with a handjob from the front, and it's a pleasure I can't get when I'm alone.

 Miyu was not used to the handjob, and her extra-moving body shook her breasts that were wearing underwear. The round surface, where most of the skin area was visible, was swaying gently and stimulating my sexual appetite. It must have been Miyu's first time handjobing me, but she quickly caught the place where my dick felt, probably because Miyu had been watching me when I was shaking many times...

「Aah, oh, oh, that's amazing... It looks like it's about to come out... Miyu......!」

「Yes, hurry up and take it out. Take out everything that has been collected」

 When I tried to adjust the position of my cock so that I could feel stronger stimulation by having Miyu wrap her fingers around it, my hips moved. Miyu looked down on me like that.

「Ah, ah, ah...! I'm going to cum... I'm going to cum!!!」

「Oh, it will come out soon huh. Although I just did it with my hand, making a pitiful sound like a girl」

 Miyu's hand rubbing my dick became faster, and Miyu, who was already used to moving her hand back and forth, gripped my dick hard and opened her mouth as if she was ready to drink my semen.

「Hmm...Hurry up, spit it out....」

「Ahhh, Miyuu, Miyuuu.........!!!」

 Byururu, byurururu, byukubyuku, byuu, byyubyuu──!!!

 With Miyu's handjob, I ejaculated without hesitation. As instructed by Miyu, all the semen stored inside the balls was pumped and poured into Miyu's mouth.

「Hmm... amu... hlurp... I feel like this came out more than usual」

「I'm sorry. It tasted too good」

 If my arousal increases, the amount and viscosity of my semen will also increase. When I got a masturbation from a cute loli, Miyu, the amount of sperm released was not comparable to before.

「Come to think of it, you used to wear lacy clothes with hair like that. Why don't you wear it anymore?

「It's about the lower grades of elementary school. My body is almost mature now. that kind of thing....」

 Miyu looked down with a complicated expression. is there something wrong with her? Even if I'm already a member of society, I want Miyu to wear cute clothes.

「Well, that's all. I'm not asking you to do it by hand, but is it good?」

「It wasn't good and I won't do it again. When I heard Onii-chan's panting voice, it made my ears hurt.」

 Miyu said that with an unchanged face, rubbing her exposed knees from her pink lingerie and fidgeting.

 For some reason, the area behind me feels itchy.

I wonder if Miyu also has that kind of feeling.

「You're still beautiful even so.」

「I don't need that kind of consideration. However, there are various emotions swirling around, such as regret for what you have done, even if it is momentum. Leave me alone for a while」

 Miyu is now hiding her panties with her arms, and although her body is hot, her eyes are telling me to leave the room. Apparently, even being on that second floor made me feel uncomfortable. I somehow understand her intentions, so I apologize, but my heart is beating fast. As expected, I should try not to think about naughty things anymore.

「It's my turn to cook starting this week. I'll make it, so come anytime」

 Our parents come home late at night, so the two of us often take turns to cook and eat together. Due to the convenience of food management, we basically take turns every week.

「I'm already full because Onii-chan has made me drink, so it's fine if I'm going downstairs late」

 Miyu said so while rubbing her stomach and kicked me out of her room.

 After going down to the first floor, I thought about today's events to my sister who casually exudes eroticism. I don't know about her relationship with Haruka, but she gave me a hand shake while looking at Miyu's cute loli underwear, so it was a satisfying day.
