I made an appointment to have sex with Yamamoto-san and went home feeling light and surreal.
It's my turn to cook today.
The contents of the fridge were small, but I didn't dare to buy more.
"Onii-chan, welcome back."
"I'm home."
While I was standing around absentmindedly in the kitchen, Miyu, who was packing her things near the entrance, came over.
Miyu is going on a trip starting tomorrow.
Even though I say she's packing her things, she only packs what will fit in her tote bag.
It seems that clothes and other items are provided at the accommodation.
What kind of extravagant trip is she going to take?
"Are you done packing?"
"I'm done. I'm hungry and want to eat."
"I'll make it now."
The rest of the ingredients are cheese, onions, and meat.
We have a high wattage microwave oven that Miyu had our parents buy for her, so we can fry things up and make gratin.
While I was cooking, Miyu was playing with her smartphone on the sofa.
It's unusual for Miyu to be glued to the screen, as she doesn't often contact her friends.
"What are you doing?"
"Majomaru."
"Majomaru? …you mean, the app I was playing?"
"That's right. I got something rare so I'm continuing."
It's a common addictive pattern for gacha games.
I don't know about the major companies, but I've heard that some of them predict the user's gender and age based on their playing habits, making it easier to match characters.
Miyu continued to play the game until I finished cooking.
In the past, she was the type of person who would complain every time I played a game, so it's refreshing to see Miyu so absorbed in a game.
Miyu is sitting on the sofa with her back straight, carefully holding her smartphone with both hands and playing the game.
It looks like a squirrel eating food, so cute.
I wonder how much progress she's making.
I'm very curious.
I quickly transferred the ingredients to a heat-resistant plate, threw it in the microwave, and absentmindedly grabbed my smartphone and approached the sofa.
Miyu notices this and suddenly looks up at me.
"Onii-chan, Onii-chan."
Miyu showed me the screen of her smartphone.
What was displayed there was her Majomaru user ID.
"Let's be friends."
Friends-- What Miyu said was one of Majomaru's game systems.
By using this friend function, users who become friends can share their strengths and help each other.
Once a friend request is approved, you will become friends, and the characters you have raised will be able to be used by others.
I started a few days earlier than Miyu, but thanks to Suzuhara teaching me strategies, I was able to progress faster than other users.
In the early-game, just using my character makes you unrivalled.
Whether it's fun for Miyu or not, I guess I'll have to let Miyu decide for herself.
When I searched for Miyu's ID, a user named 'Miyu' was found.
"Level 25, huh. You're surprisingly making a lot of progress."
"I was doing this all the time after I tied up Yuka and until Onii-chan came."
How the hell can she remain so empty-minded after being so angry before.
Even though she's my little sister, she has a terrifying heart of ice.
"You're free at night, aren't you? Why don't you join me after we eat?"
"Okay. Here you go."
I laid out dinner on the table and sat down across from Miyu.
We won't be eating together for a week from tomorrow.
I'm happy to see Yamamoto-san, but it's going too be lonely when no one's at home.
"Where are you going this year?"
"Hokkaido. The flowers look pretty, so we're going for a walk. Then we'll just eat."
"So you're going to stay for a week?"
"There are many other purposes as well."
Miyu munches on the gratin while stuffing her cheeks with a spoon.
She replied indifferently, but in short, she's going to be with the lesbian Haruka for exactly one week.
"Are you staying at an inn?"
"Probably a villa."
Villa... a term used by rich people.
Everything is so different from the travel I know.
"Haruka is rich, isn't she?"
"Haruka's family is an ordinary family. It's just that the Onee-san Haruka befriended at work was rich. ...Then again, the only people who are coming are strange people who have too much money. That woman seems like she's going to be our driver."
Is a car essential if you want to go around Hokkaido?
An Onee-san who wants to support two junior high school students on their trip... what kind of weirdo is she?
"What's Haruka's job?"
"Hmm... a model, I guess. I can't say more than that."
Why.
"It's not like I'll do any research though."
"That's not the problem. Just don't get interested in Haruka."
Miyu stubbornly refuses to let me know anything about Haruka.
It's in human nature to uncover what's hidden.
However, Miyu is also my benefactor, so if she hates it that much, I guess I shouldn't ask.
"What will Onii-chan do during summer vacation?"
A question from Miyu.
I guess that's how the flow of the conversation is.
"I got a part-time job. Other than that, well, I'll be meeting with Yamamoto-san tomorrow."
"For dirty stuff?"
Miyu's words hit hard.
Did she mean to bait me or did she know everything from the start?
"I think we're going to."
"I see. You're doing your best, aren't you."
"It's just a stroke of luck."
Was there something I did my best to do?
Everything was a product of chance, and Miyu was the one who created that opportunity.
"It's good if you can become independent of your little sister."
Miyu finished the gratin and gently placed the spoon down.
After we finished eating, Miyu and I sat side by side on the sofa.
When we're this close, I can clearly see how small Miyu's body is.
She's so adorable I'd embrace her and wrap her around my arms.
I want to touch her regardless of my sexual desires.
I was leaning against the backrest and watching Miyu play the game with impeccable posture from behind.
Beautiful black hair that grows parallel to her back.
These backs are the kind of thing I suddenly follow with my eyes when I'm walking down the street.
When I pass someone and catch a glimpse of their face, I often don't like it though.
This sister in front of me is perfect down to the smallest detail of her body, not to mention her face.
There was no other reason why I could monopolise a girl who cared so much about me than because I was her older brother.
I have to remember that just being able to live together like this is a blessing.
"Onii-chan, which one should I raise?"
Miyu showed me a list of her characters.
It's full of rare characters.
"If you develop a good balance between recovery types and attack types, you won't lose. Most of the characters have strong animal evolutions."
"Ehh. I wanted to make her a witch though."
Miyu taps the evolution button while grumbling.
As she progresses through the evolution screen, I can see the branch destination in which the witch child evolved into.
Apparently, the fox animal Yoko is Miyu's favorite.
Majomaru has two evolutions: one that evolves into a magical girl, and one that evolves into an animal.
There is no doubt that both are cutely deformed, but the witch-like evolution is still popular among girls.
If I push her too hard, she won't continue, and I'll miss the time to talk about my hobbies with Miyu like this.
Unless she values efficiency like me, it's best to let her do whatever she want.
"In that case, this site lists strong character combinations, so why not use them as a reference? It'll be fun to decide which units will support Yoko and proceed with the strategy."
"I see. Uh-huh uh-huh."
Miyu is smart and good at what she does.
However, in games, there is something called 'game intuition' that cannot be compensated for by quick thinking alone.
Miyu seems to be getting the hang of it, but only experience matters here.
It looks like I'll be able to stay her senpai for a while.
Then I continued playing the game, and when the battery ran out, I brought the power cord and continued playing for another 2 hours.
It worries me that I'm about to get tired, but Miyu's motivation doesn't fade.
"With Onii-chan, I can clear difficult quests, so my level will go up a lot..."
"In the early-game, you can recover your stamina as you level up, so you can take on quests as many times as you like."
There are two aspects to the friend feature: a feature that allows you to use one character from a friend, and a feature that allows you to borrow the strength of multiple characters from nearby users.
In the type of games where characters are acquired through gacha, if the skill of the player becomes irrelevant, only some characters will be used and people won't spin the gacha, so the system is set up to ensure that an attack will always land at some point.
This gives meaning to the existence of recovery and defense characters, and if you borrow just one character, you won't be able to clear the most difficult quests in Majomaru.
"Shouldn't you take a break?"
"Then I'm going to take a bath. In the meantime, Onii-chan, please clean up the dishes."
"Got it."
Miyu quickly entered the dressing room.
When I was little, she got so grumpy when I played games.
People change as they get older, I guess.
After cleaning up the dishes, I went into the bath after Miyu, and since I didn't want to keep her waiting, I quickly got out, dried my hair, and put on my pajamas.
Miyu seems to be in her room, so I knock on the door.
The door was quickly opened.
"Did you brush your teeth?"
"Haven't."
"Then hurry up and brush it."
"Yes."
Click.
A door closed ruthlessly.
I brushed my teeth as I was told.
Miyu was fully prepared, and the only thing left to do besides play was sleep.
I guess I should do the same for her.
After getting ready for bed, I visited Miyu's room again.
"I'm done brushing my teeth."
"Okay. Go back to your room."
Looks like we'll continue in my room.
Girls are resistant to letting a man, even if it's their older brother, into their room, huh.
While I was sitting on the bed, Miyu came into my room and sat down next to me.
Grabbing her phone along with a pillow.
"Why a pillow?"
"Because I'll wake up early tomorrow."
Yeah, if that's the case, we'll wake up at different times, so I think we'd normally sleep separately.
"When I slept with Onii-chan last time, I fell asleep really well. That's why I'll sleep here."
"I see."
Since she didn't even ask for permission, I guess she didn't think I would refuse.
Of course, there is no reason to refuse.
"Does Onii-chan have free time to play Majomaru?"
"Not really. I don't have as much stamina as Miyu does. I think I'll try playing games on the computer instead."
"Dirty games?"
"Those have already been sold by Miyu."
"That did happen."
I could have just not held back and bought a new one, but.
My sex life is incredibly fulfilling.
Since I can no longer take pleasure in anyone other than Miyu, I no longer even look for erotic images on the internet.
"That's how I started playing Majomaru. Suzuhara asked me to participate in an offline game meeting. I'm not really into it, but I thought it would be a good idea to expand my hobby, so I decided to start playing again."
Originally, I mainly played online RPGs.
When the game was first released, the balance of strength was sometimes skewed in favour of certain characters, and I had to hone my skills as a player to compete in the rankings.
In the world of online games, those who purchase in-game items have the advantage in the end.
I was tired of filling that gap.
Even so, I still had the habit of spending time playing games, and after Suzuhara encouraged me to do so, I started playing eroges all the time.
"Then you can play computer games. I'd like to see that too."
Perhaps because of her habit of playing games, Miyu began to take an interest in computers.
For me, I'm really happy because the areas I can talk about with her are expanding all of a sudden.
Miyu is in multi-mode by herself with both my smartphone and her own device.
A fine gamer.
I also log into the online game and join a random party.
There isn't any conversation, and the game progresses by simply sharing a room.
I guess this is what it would be like if I had an offline game meeting with my online friends.
After a while, Miyu came to my side.
That said, she's only been looking at the display ever since.
Even when I asked if she wanted to play it, Miyu refused.
While feeling an inorganic gaze behind me, I completed the quests prepared as part of the story.
After about two hours, it was all over, and the next thing I knew, Miyu was sitting on the bed, hugging the pillow.
"Are you going to sleep?"
"Sleeping. Onii-chan should go to sleep early sometimes too."
Miyu pats the bed.
The time was just past 10 o'clock in the middle of the night.
It's quite early, but I'm going to be tired tomorrow, so I think I'll go to bed already.
Above all, if this little sister is inviting me, I can't refuse.
After shutting down the computer, I crawl into the bed and Miyu sleeps next to me.
After darkening the room and allowing my eyes to adjust, I could clearly see that the single futon had the body heat of two people.
When I turned inward, I met Miyu's eyes.
Her white skin was illuminated by the moonlight, making her well-defined face look even more beautiful.
...Why am I in the same bed as such a cute girl?
"Will it bother you if I stick together with you?"
"Eh!? N-no, not at all..."
Miyu closed the distance with me and got in close contact with me.
Also, there isn't have a gap in her lower abdomen like before.
It was complete close contact with her legs wrapped around me.
The body temperature of Miyu is gradually transmitted throughout my body.
Warm and soft.
This is strange.
Why is she so aggressive?
Is she going to punish me again?
Did I do something again?
Miyu's head is right under my nose, and the smell of her hair inevitably stings my nostrils.
A stretchy nightbra and thin pajamas.
Because the breast meat doesn't flow sideways, I can feel the flesh of her boobs more directly.
Miyu's body retains the necessary amount of fat, but she is basically slim.
When she hugs me, I can clearly feel the skeleton of her entire body.
Hugging me tightly, Miyu drew her body closer to me.
That's consent, isn't it?
And naturally, heat is concentrated in my lower body.
Even Miyu should be prepared for this.
There's no way I can hold back.
Thanks to the softness of our pyjamas, we can really feel each other's skin.
My swollen lower abdomen hit Miyu's crotch.
The hardness of that cock must be hitting a girl's most sensitive area.
Still, Miyu was sleeping peacefully.
She seems to be very comfortable in my chest.
When I slept with Miyu, I fell asleep surprisingly easily.
I didn't feel like falling asleep yet because I went to bed early today.
I rub her lower body and press against Miyu's crotch.
While hugging Miyu, I forcibly pressed our erogenous zones against each other.
"Ah... haah..."
I don't know what's going on down there.
Because Miyu's breasts are so big that I can't look into them even if I create a small gap.
However, I can clearly see the shape of her breasts change when I press my body against hers.
My pyjamas are just a shirt and shorts.
It might just be my imagination, but I can feel the hardness of Miyu's nipples.
Above and below, I'm rubbing the sensitive parts of Miyu.
Even so, she didn't complain, so Miyu must have already fallen asleep.
It seems I indeed had the effect of inducing sleep as much as she wished.
But I can't stand it anymore.
I can't stop pushing my penis against Miyu's crotch.
"Ahh... Mi... yu..."
I enjoy Miyu's body and my sexual desire swells.
No matter how bad it is, I have no intention of stopping.
I'm sure Miyu doesn't think I can stand it either.
It's bad that Miyu invited me like this.
Even if this was another punishment.
It's impossible for me to hold back.
"Fuuh... haah... haah..."
Even with our clothes on, her soft skin and my hard meat continue to press together.
Only the sound of the futon and our clothes rubbing reached my ears.
The area I'm rubbing my penis against is Miyu's pussy, a girl's erogenous zone, and her clitoris.
The fact that I'm circling Miyu's clitoris is the most exciting thing.
I'm about to ejaculate.
But I don't know where to let it out.
At this rate, my underwear will get soaked.
I can't cum.
Contrary to my thoughts, my hips began to move more violently.
"Aahh, haah... Miyuu... Miyu... aaahh! F-feels so goood... auhh...!"
I'm on the verge of orgasm.
I can still do it.
Just get my hips off her.
I can do it in just a little while.
Feels good.
Ahh, Miyu, I'm at my limit.
"Nnnh... Onii, chan...? What are... you doing... ah-... n-!"
Just before I was about to stop my hips at the limit of ejaculation, Miyu regained consciousness.
Miyu's lustful voice caught me by surprise, and my desire to ejaculate, which I had almost suppressed, suddenly burst out.
"Aahhh, s-shit, Miyu! S-sorry! Ah-..."
"Fueh!? What happened!? O-Onii-chan!?"
I immediately turned on my back and put my hands in my pants and shirt, lifting my clothes.
The semen that was ejected from my warped cock just splashed into my clothes and soaked my stomach.
Although I managed to avoid staining her clothes, Miyu woke up in shock.
She looked around and looked into my face, which was frozen in place.
"Um... Onii-chan...? By any chance, did you cum?"
"Y-yeah..."
Apparently, she was aware that her crotch was being used at the very end.
Even if it was only for a moment, it was enough to let out a moaning voice.
"Come on. You're not an idiot, are you, Onii-chan?"
When Miyu realized that the situation was just me running out of control, she covered herself with the futon again and laid down.
"U-um, Miyu-san."
I'm holding my clothes up to avoid getting semen on them, so my hands are buried inside.
If this continues, I won't be able to move unless I give up on my clothes becoming sticky.
"If you don't mind, I'd like you to wipe it off."
"No. It's your own fault."
Miyu sulked and clung to my arm while I was lying on my back.
Then she closed her eyes and began to sleep peacefully.
Are you really planning on telling me to spend the night like this?
That was my fault for ejaculating on my own though.
But at least stop sealing my arms please.
Nearly five minutes have passed since Miyu fell asleep.
I was completely frozen, unable to move.
What do I do.
If I didn't have the futon on, I could just lift up my shirt and wipe away the semen.
"Nnh... uuu-n...."
Miyu groaned and changed the way she hugged me many times.
It seems like she hasn't even gotten into a deep sleep.
Then, after a while.
Miyu opened her eyes and stared at me.
"I can't sleep because of Onii-chan."
"M-my bad."
Apparently, because I pressed too hard into her lower body, she felt uncomfortable, and Miyu sullenly sipped her mouth as her inner thighs wiggled.
I was wondering if I had made her angry again, but Miyu got up and lifted the futon over me.
While I propped up the clothes and created a gap, she shifted the clothes that were stuck between the mattress and my back.
"Jeez. Letting this much out. Kanade-san's share will be gone."
"I-I'm sorry. "
I can't help but apologise to Miyu.
If I told Yamamoto-san that I couldn't have sex with her because I ejaculated too much, she would probably get angry.
I have to put up with it today.
"Stupid Onii."
Saying that, Miyu tied her hair to one side like she does when she eats food, brought her face close to my abdomen, and started licking up all the semen.
"Ah, aahh, aahhh!!"
The heat of Miyu's saliva overrides the lukewarmness of the semen.
Her tongue moistened with saliva crawls over parts of the body normally not touched by other people, and my sensitive nerves receive immense pleasure.
"Aahhh, Mi-Miyu! That's, bad, aah, gaah... it's feels too... good...!"
"It's fine, okay. Don't struggle. It'll start dripping down your sides."
Miyu preferentially licks away the semen from my side.
It's a more sensitive area than the center.
I can feel every detail of her rough tongue.
"Hah, nh, nnh! No, Miyu, I'm gonna, again...!"
There's no way my sexual desires can remain calm when something like this happens to me.
My penis was as erect as it was just before I ejaculated.
"Nchuu, munyu... nh... jubu. ...Alright. You released way too much."
Miyu swallowed all the semen that was sprayed onto my stomach, then lightly covered her mouth and exhaled.
"Haah... haah... Mi-Miyu, um, if you do this, I'll want to cum again."
"What excuse are you going to make if you can’t have sex tomorrow after letting out so much?"
"About that..."
It was my fault I ejaculated.
However, I never thought that she would lick the semen that was let out outside.
Even though she was apologising to me when she saw me having a wet dream, she didn't use her tongue so hard to clean me up.
It was a pleasure like nothing I had ever experienced before.
I can't sleep in this state.
"I-if I say I want to cum again, will you get angry...?"
"Hmph."
Without letting me put any clothes on, Miyu lays down next to me and looks at me sharply.
"Actually, I'm already angry."
"That's right! Of course that's so! I'm sorry about that. Really, I'm sorry."
I used her body to do erotic things without permission.
She deserves to be angry.
"You're always like that, ejaculating as you please."
"Sorry."
"'I want to cum, I want to cum.' It must feel great to be sexually honest. Even to your blood-related sister."
"It's truly my apologies."
Even though we slept together tonight, Miyu might just have wanted to get along with me.
I left it to my sexual desire and did something terrible again.
Why don't I reflect on this?
"Muu..."
Miyu is dissatisfied, but still clings to my arm.
Then, she pressed her body against me again, rubbing my inner thighs.
"Miyu?"
Miyu asked me to sleep with her because she would be calmer and fall asleep faster that way.
Now that it's like this, there's no reason for Miyu to insist on sleeping with me.
Of course, I don't want Miyu to disappear.
I wonder why Miyu is still by my side.
"Uuu..."
Miyu put her fingers inside my clothes and squeezed my chest hard.
It hurts, but I'm more concerned about Miyu's condition.
"Are you... all right?"
The way she gets angry is strange.
She remains restless as she keeps moving her body.
"Why did you use my crotch more than anything..."
Miyu's body gets closer.
If I'm not mistaken.
Rather than being angry.
Is she... in heat...?
"I'll punish you after all."
Miyu's arm extends to my lower body.
That hand grabbed my cock without hesitation.
"Ah, Miyu, what are you...!"
Miyu started stroking my cock.
Miyu's slender fingers press against the pressure points of my penis with delicate movements.
"Ngah, ahhh, Miyu, if you do that, uaahhh...!"
The desire to ejaculate suddenly wells up.
She says it's punishment, but it's just play.
Miyu is giving me a handjob.
That Miyu is teasing my penis.
"Aguh, ah, ahh, aahhh...!"
For some reason, Miyu's hands have a perfect grasp of my pleasure points.
Yamamoto-san's sense of flesh and technique are superior.
But I am assured.
Being touched by Miyu's hands feels overwhelmingly better.
The quality of excitement is completely different.
The fact that this little sister is doing erotic things to me excites me more than anything else.
"Haah, haah, Miyu, I'm already cu-cumming...!"
Miyu's hands become faster in line with my reaction.
I can tell even if she doesn't say it.
'Let it out,' Miyu says.
She wants me to let out my semen for her.
"Miyu, aaaauhh! Cumming, cumming, ah-, ah-, aaahhhh!"
Dopu, dopu, an amount of semen that doesn't think about tomorrow was spit out on my stomach again.
There was so much flying around that the semen reached my chest.
"Miyu...?"
"What?"
Miyu was just staring blankly at me ejaculating.
Her reaction was cold, but Miyu still let me ejaculate with her hands.
"Speaking of which, this is probably the first time I've properly seen Onii-chan cum."
"Eh, ahh, that's right."
I had to either ask Miyu to drink it or give her a bukkake.
It had been a long time since I had been observed like this.
Miyu gets up again and puts her hair behind her ears.
She's going to lick my semen again.
What do I do.
Although I was able to ejaculate.
I wonder if she'll get horny again.
"Hummu... nyummuchu..."
"Aguh... nnh...!"
My expectations weren't betrayed as Miyu started licking my body.
I get excited just by having her drink my semen.
If I were to be cleaned like this, my sexual desire would never subside.
"Ah, aaahh! Ah-, th-there! You can't do it there, auhh-!!"
Miyu's mouth started sucking on my nipple.
It couldn't be helped if there was semen on there too, but it seems like she has no intention of calm my sexual desire by licking such a place.
"Are you that sensitive?"
"...Apparently, yes, it seems."
I've never had anyone lick it, and I've never played with it myself.
I thought I would never feel my nipples unless they were developed.
Worst case scenario, it would have felt better than getting a blowjob.
"Huh."
Miyu licked the semen from my whole body.
However, I still couldn't get her to lick the semen that was on the tip of my glans.
When the process was finished, Miyu brought her face close to my chest again and started licking my nipples.
"Auh, ahn, ah, ahh, ah...!"
"You're panting too much. Is Onii-chan going to make such noises when you have sex with Kanade-san?"
"No, that's... nh... haahnn...!"
Perhaps it's because Miyu is used to having sex with women, but her nipple stimulation was several times better than her handjob.
I was like a fish on a chopping block, just being tossed around by Miyu's licks and continuing to be tortured with pleasure.
"Haah, haah, haah... nguhn... aahh... feels so good... I'm dying..."
"Yes yes. Great for you, right."
Once Miyu was satisfied with her licking, she laid down beside me again.
The look on her face was so grumpy that it was hard to believe she had played with someone.
"U-um..."
After all this, it's no time to start thinking that maybe I'm misunderstanding something.
"Should I do it to Miyu too...?"
"I don't know."
Miyu pulled down my T-shirt and just hugged me like a koala.
I put on my pants as well, and for the time being, I adjusted myself to Miyu's position.
"Sleeping."
Miyu said so and closed her eyes.
As expected, Miyu may not even want me to touch her body.
But nevertheless, I am truly sorry.
My cock was still stiffly erect.
As it should be.
There's no way I can stay sane after her giving my nipples so much pleasure.
I still feel the sensation of being licked and sucked by Miyu.
I still want it out.
I want to ejaculate, just one more time.
I'm supposed to have sex with Yamamoto-san tomorrow.
I'm sure it'll recover overnight.
Last night I ejaculated five times, and today I am ejaculating so much.
I finally realised it now.
I have a sex drive several times stronger than other people, and it seems my resilience is just as high.
"Miyu..."
I embrace Miyu and feel her body temperature all over my body.
It's much hotter than when we first hugged each other.
Miyu's body is on fire.
I don't know if it's her intention or not, but Miyu's body is definitely in heat.
"Miyu, just one more time..."
I pressed my penis against Miyu's crotch again.
Men don't just get excited when they're having something done for them.
Rather, a male's instinct is to drown females in pleasure.
Miyu must still be awake.
No matter how much she gets mad at me later.
I want to make Miyu's body feel good using my penis.
"Nhah, Onii-cha... nnh..."
Pressed my cock against Miyu's crotch, a whisper also leaked from Miyu's mouth.
She doesn't even try to shake me out of my rampage.
No matter how hard I press my lower body against her, Miyu just tries to suppress her moans and doesn't let go of my body.
"Aah, Miyu, Miyuu... feels good..."
"uu... fuu... nh... ah-..."
It hits Miyu's private parts.
My hard cock.
That's what Miyu's feeling.
I feel like I'm going crazy.
Pleasure and happiness wash over me like a tsunami, and my mind becomes vague as if it has evaporated.
When I press my hips against hers, Miyu lifts her legs accordingly and hugs me tightly.
While her lower body was searching for pleasure, her arms were trying desperately to keep her whole body strong so as not to let out a moan.
Such admirable behaviour is cute.
Most of all, I love her more than anything else.
"Ah-, Miyu, I can't anymore, ah, cumming...!!"
"Fueh, auh, wait... just, a little... more...! Nnh-...wai-... hwe-...!"
Miyu's private parts face upwards as she raises one leg.
There was no way my desire to ejaculate could withstand the fact that the sponge, filled beyond its blood limit, would fit into the groove under Miyu's clitoris and continue the act almost equivalent to intercrural sex.
Intercourse with our underwear on.
If I keep rubbing like this, the inside of my underwear will get wet.
"Miyu, sorry, I'm already...!!"
"Onii-chan, it doesn't matter, if you cum-, so just continue, a lwittle, more- anh-, nn... ah-, nn-...!!"
"Miyuu... ah... haaah, uuu, ah, Miyu, cummingg, cummingg...!!"
Even as I ejaculated, I continued to move my hips violently, just as Miyu wanted.
Eventually, the strength of Miyu's arms as she hugged me increased to their maximum, and then, suddenly, Miyu released her tension, as if her whole body was going weak.
"Haah, haah, haah."
I'm the only one breathing heavily.
Miyu even resisted letting her erratic breathing be heard.
"Mi-Miyu, did you... cum...?"
When I asked, Miyu covered her mouth and shook her head.
"I'm sorry about that! Um, also, do you want to do it again?"
Miyu still shakes her head in response to that question.
"Is it really fine?"
"It's fine. Girls can feel satisfied even without cumming after all."
Miyu took the futon from me and used it as a pillow to hide her body.
"Forget about today, okay."
Miyu has made the most demanding order ever.
If I could forget something like this, there would be no worries in my life.
"Onii-chan releases a lot of semen like an idiot. I have to brush my teeth again. Seriously."
"Sorry..."
Miyu got out of bed and pulled and straightened her disheveled clothes.
And then.
"Onii-chan..."
She lets out an exasperated voice as my lower body was still pitching a tent.
"Well, this is, um, Miyu is so cute, I can't help it anymore."
"Grrh!"
Miyu slammed the tissue box on the bed, threw the door open, then turned around and pointed at me.
"If it's not smaller by the time I get back, I'll make you cum!"
Miyu walks out into the hallway, stomping on the floor.
After all this, my little sister made me ejaculate another two times.
