for Advance Chapter
We ended the kiss and pulled apart slightly.
The location was my own bed.
Komari, naked only from the upper body, carefully collected what I had released in her hand. When she looked at it, she—
…Kuchu… Chururu!! ♡
"!"
"Nn… Ah, nn… Reru, kku… Nn, nku."
She carefully scooped up the semen with her tongue, chewed it, then swallowed. She repeated the motion of licking, savoring, and drinking it down.
"…You don't have to look if you don't want to."
"No, I don't need it… So, please drink it."
"Ordering me to drink semen… You… You pervert!!"
With her face flushed red, she delivered her usual Komari-style retort.
Somehow, even at a time like this, I felt relieved that Komari was still Komari.
"Hey, Nukkun♡… Share some with big sister Lemon too."
"Hey hey, Nukumizu-kun♡… Mama Yanami wants you to let her drink some too~"
"F-For both of you… Please stop that… Komari, don't pull away!!"
It was Saturday. As usual, the three Literature Club girls had gathered in my room at the Nukumizu house, and just like a harem eroge sex scene, we were having exactly that kind of harem sex.
Yanami-san completely naked, Yakishio in her underwear, Komari half-undressed.
They came to the room, casually stripped, and spent the day in lazy, sex-filled daily life. No matter what we did, some part of my body was always in contact with someone's soft place or wet place, and pleasure constantly accompanied me.
"Tongue out. Nukumizu-kun's mouth looks delicious♡… Seriously, I want to make this my diet menu♡"
"Nukumizu… Hey, I want you to touch me… It's already so wet here… I can't hold back anymore… Ah, later… In return… You can… Pound me hard, as much as you want♡"
"Nn, then I… want to smell Nukkun's nice scent a lot♡ Taste it a lot♡… I'll give you a blowjob~♡"
…Nuchuri, kuchu kuchu, juru juru.
Hands, mouth, cock—there was always someone's heat, softness, and lewdness.
Without any gaps or free time, the sexual acts with Yanami-san, Yakishio, and Komari constantly surrounded me.
Against three cute, lewd girls, thinking any further would mean overusing my worldly luck and making the next life scary.
Nevertheless.
Recently, another problem has arisen.
〇
～Night～
The bedsheets were far too clean no matter how you looked at it. Even the smell of the room was almost unnaturally fresh. The fact that I hadn't questioned how she could instantly wipe any dirt with disinfectant sheets showed that living with an overly perfect little sister had numbed me.
"…Kaju."
"It's fine, big brother. Taking care of you is the happiest thing in the world for Kaju."
She answered while gently stroking the clean bedsheets.
As always, she was excessively devoted toward her brother.
"…It's okay. I didn't make any noise, and… I installed speakers in both rooms to prevent any sound above a certain level from being heard. The doors also have soundproofing measures, so even if someone listens at the door, there's no problem."
"I-I see."
"I also installed infrared sensors in the hallway. And though it might be overkill, there's a listening device—no, a smart bug in the room that shows on a smartphone app whether someone is breathing while asleep."
"…Kaju… Maybe you should keep a little distance from Asagumo-san."
"Ehh~, but I still have so many questions about hacking techniques… Kehon kehon."
My dear sister, that cough to change the subject is way too late. It's like trying to do cardiac massage after cremation.
"…Well, for now it's fine."
…Gishi.
"———"
"Big brother, you smell so nice… Nn… Fufu, such a wonderful scent♡"
"…It tickles."
I pushed away Kaju, who was snuggling against me. I compromised by letting her rest her face on my arm and hug it.
Lately, the skinship at night has become really intense.
"…It's not fair. Everyone gets to be so close with big brother… Kaju is the only one who has to hold back and go out on days off. I don't like it anymore."
"About that… I do feel sorry. Yeah… So on Saturdays everyone…"
"Having sex with everyone on days off… has already become an unstoppable habit, hasn't it?"
"…D-Don't say it… It's, um, force majeure."
While staring at the tapestry on the wall, I felt the heat of my little sister clinging sweetly to my arm.
Kaju remained the same Kaju, always close as family, admiring her brother, taking care of him, and acting spoiled.
However, since that day, Kaju had changed. No—she had simply stopped trying to hide that she had changed.
"…The kiss with Komari-san was really wonderful."
"Ah… I see, so that's how it looked. I don't know if I'm good or bad at it."
"It would be rude to say it's because it was Komari-san… but the secret meeting between Komari-san and big brother felt like I was really there."
"…"
"Fufu, big brother, big brother♡… It's okay. Kaju only feels a tiny bit of jealousy… Other than that, I'm the usual Kaju who loves her big brother. Nothing has changed, nothing♡"
She nodded and rubbed her forehead against my chest.
Thinking she was asking to be petted, I gently stroked her beautiful black hair. The smooth, silky texture made my hand feel like it would slip right off.
She had carefully washed it, and the scent of an expensive shampoo she didn't usually use drifted from it.
Even her clothes weren't her usual pajamas.
It was a lewd, see-through babydoll that made me wonder where she had bought it.
Even an idiot or a blockhead could understand that she was fully motivated.
"…Big brother♡… Tonight as well, I'll take the hush money♡"
"G-Go easy on me."
That day, I learned that my little sister knew everything.
In these days of living an eroge-like harem life, there was no way nothing would happen involving the existence called "little sister."
I didn't want to admit it. But I had felt a premonition strong enough to accept it.
Still, even so—
"Big brother… It's okay. Kaju will endure with just her mouth♡… Because Kaju is a good girl♡"
I thought "There's no way my little sister is this erotic," but it was in vain.
"It's okay. Big brother can just relax♡… Leave everything to Kaju and spoil yourself in Kaju's mouth♡"
"I don't have as much as Yanami-san, but I like it too♡… I can't do it as intensely as Yakishio-san, and my mouth and tongue are small like Komari-san's… But I'll still do my very best to serve you comfortably♡"
"So… Big brother♡"
Gently, her hand pushed my shoulder.
Lying on the bed with the pillow raising the angle, in my lowered field of vision, Kaju had already finished preparing.
With her glossy, exposed skin, she bowed toward the bulge in my pants. Her innocent eyes turned seductive as she placed a light kiss over the fabric.
The tip reacted, and despite the intense session with the three girls during the day, blood rushed back at full speed.
The erection switch had been flipped.
"…Fellatio… With Kaju's fellatio, please fall asleep comfortably♡… Good night, big brother♡"
"————!!"
The lights in the room went out.
Even after learning the secret, Kaju offered one condition to keep it: she wanted to help put me to sleep.
"Don't worry, I won't make any mistakes," she said.
She wouldn't use her hands. She wouldn't take off her clothes. She would only use… this.
"…Ah, rea… With my tongue♡… As a reward, I'll make you feel really good♡"
After saying she would serve me, Kaju stopped speaking entirely.
The only sound that could be heard was the lewd melody of oral service.
…Kuchu… Juru, reryu kuchu.
…Chupu, chupu, chupi!! …Kuchu, rerureru!! ♡
...Churu, chu… Jururu!! ♡♡
To be continued.
