Noona Under the Desk, Part 1
"Am I your slave or something♡... Just because that dick of yours is a bit big♡... Acting all high and mighty♡..."
So it really was masturbation based on reality.
"Kuuu..... Huoooot.... Please... Let me cum... Master... Hit me more♡..."
Noona had those kinds of tastes too, huh...
Wait, no... At first it was the complete opposite, wasn't it?
"Uuuugh♡! Fuck♡! You worthless bastard♡..!!!"
"You evil piece of shit♡...! Rapist♡!!..."
I am a bad bastard, but rapist...? Is that one accurate?
Might as well take a closer look. What kind of porn is she watching?
I'd assumed a woman would go for something warmer and softer, but this was the ultimate hardcore genre. A woman getting exposed to men, unable to even breathe as she was completely broken.
Should I let her know I'm here now?
I should at least respect her privacy...
Though I'm not sure how much privacy she has left to protect.
She was furiously masturbating while verbally spitting out her masochistic and defeatist desires, all while watching hardcore porn that perfectly matched her thoughts of me. I'd seen every last one of her secret, shameful preferences.
It was unfortunate for her, but for me the situation was unbearably arousing. I strode straight toward my sister.
“Noona, you were badmouthing me, huh?”
My voice was full of mischief as I informed her that I'd heard every word.
The moment she heard me, our Noona flinched hard and whipped around.

"...........!?"
".....Kyaa..... Kyaaaaaaaah!!"
The instant she saw me her face flooded with pure horror.
"Why are you screaming like that...? Did you see something you shouldn't have?"
Noona had been so lost in masturbating that a thin trail of semen was already leaking from the corner of her mouth. In her panic her lips had fallen completely open.
What a waste of perfectly good semen.
That was all experience points.
I'd just have to refill her.
“W-why did you come into my room…!”
“How long have you been there, you perverted bastard..!”
Honestly, the pervert here was clearly Noona right now.
“……..A while now?”
“Did you see..? Tell me you didn’t see..!”
“Yeah… I realized my Noona had those kinds of preferences.”
“………….”
“Noona, I had a rough day today… I just want to sit down and rest…”
“…..Then why did you come into my room…?”
“To borrow the computer for a bit…”
“You have a computer in your own room! Why are you trying to use mine!”
“Because Noona is here.”
“What does me being here have to do with anything..?”
She kept arguing. Looked like she needed another lesson.
Did she actually want to be punished?
She was watching that kind of porn, after all.
“Noona, are you acting like this because you want to be punished?”
“Who the hell would want that kind of nonsense..!”
“I get it, Noona. You like it when they treat you that way, right?”
I pointed at the monitor with a playful grin.
“I’ll go easy on you. Just three punishments for now.”
“Ugh….!”
“From now on, Noona eats every meal from the dog bowl I give you… Understand?”
"...Hey?... What the hell are you saying..!"
“And this is a present for you… You’ll wear it all the time!”
"....Th-this... Are you seriously messing with me right now..!?"
I’d gone through so much trouble to prepare these things.
A dog bowl, a collar, and anal beads, all for Noona. Rushing out to buy adult toys by myself had been embarrassing enough.
Was what I was doing now even worse?
She’d shown strong rejection when I first showed them to her, but the moment I called them “punishment” she quickly became obedient.
I didn’t fully understand it, but I showed her each of the gifts I’d prepared for her one by one and made her put them on.
I couldn’t tell if she was glaring at me or enjoying it. Her face was a confusing mix of disgust and pleasure, so it was hard to read.
“And from now on, whenever I come into my room or your room, you must always wait for me under the desk.”
“…So you really only see me as a toy for your sexual release..?”
“You’re treating me like a toilet… and now you want me to spend all day under your desk in your room or mine, just sucking your dick..?”
“I’m not even a person in your eyes anymore!?”
“Noona, you’re misunderstanding something.”
“..What misunderstanding..! What more is there to say at this point..”
“The truth is… I awakened a few days ago. And my trait is…”
“……….”
“If my semen or piss enters Noona’s mouth or body, your experience points go up.”
“I know it’s weird, but you’re the only one I can do this with.”
“…….Who the hell would believe that..?”
“It’s true! The more I do it, the stronger I get. I even registered the trait recently with similar details!”
“How could you register something like that!”
“I didn’t. I just wrote that I have a strong body and enhanced physical abilities.”
“…..Fine… I understand…”
“Then… if you don’t want to be punished, you should get under there, right?”
“……..”
Noona glared at me silently before reluctantly crawling under the desk, as if she had no choice.
To be honest, my explanation had been incredibly sloppy. Had she already been trained that thoroughly?
She accepted it far too easily.

“….Sniff….Sniff♡…”
I might as well turn on the computer and sit down now.
Haa… After doing nothing but that for two whole days, I wanted to comfortably browse the internet and relax for once.
Of course I didn’t hate doing that, which was why I was making Noona service me like this.
“Noona, start sucking now.”
“…Slurp….Haa… …!”
She had been sniffing my scent under the desk while playing with her own pussy. The moment she heard my order she moved immediately.
She pulled my pants down just enough to free my massive cock.
Then she began worshipping the head first.
“Slurp… Slurrrp… Chuuup…”
I leisurely enjoyed her service while looking at the computer screen.
This sense of dominance. The immorality of keeping my sister beneath me, making her serve me while I did whatever I wanted.
My good little Noona kept servicing me all the way to the base of my shaft.
My pubic hair stuck to her tongue and face, but she didn’t care in the slightest and continued without pause.
“Slurrrp!... Chuuwaaap♡! Chooooop! Chuuup♡!”
She licked my balls, then took them into her mouth and sucked on them too.
Lick… Lick! Chu♡! Chuuup♡! Slurp! Chuuwaaap♡! Mwah♡!
Obscene sounds that should never come from a girl’s room were echoing from beneath the desk, right under me.
The way her cheeks flushed red was honestly adorable.
I didn’t really care about surfing the internet. Watching Noona serve me from below was far more entertaining.
The way she looked up at me from under the desk was just too cute.
Thank you, Father, for giving me such an adorable and wonderful daughter!
I sent a silent thank-you to my father, the goose who was still working overseas for his daughter’s sake.
Noona, completely unaware, kept focusing entirely on my cock. I decided it was time to give her a fresh load.
When she felt my cock twitching, Noona took me all the way to the root so she wouldn’t spill a drop. She pushed me deep into her throat on her own.
Before, that depth had only been possible when I forcibly grabbed her head and shoved it in. Now she was doing it herself like a good girl.
With her face buried between my pubic hair, I stopped holding back and unleashed a massive amount of semen.
Spluuuurt♡! Splurt♡! Gush! Gush♡! Gush♡!
I watched her face turn bright red as she checked my expression after I finished cumming in her mouth.
She was seriously adorable.
This was the same arrogant, prickly Noona who was now obediently following my orders, full of shame and embarrassment. She buried her face in my pubic hair and took my cock deep into her throat just to look good in her little brother’s eyes.
I wanted to use my perfectly submissive Noona like a tool as much as I wanted.
With that thought, I grabbed her head and began slamming it up and down like crazy.
It was as if her head was my personal onahole.
Every time I shook her head, I could hear the piss I’d left inside her sloshing around.
She looked dizzy, her eyes almost losing focus, yet she kept her gaze locked on my cock and my face.
I was violently using her head like a masturbation toy, but Noona desperately tried not to let her teeth scrape me.
I really love you, Noona.
Thinking that, I gently stroked her head once.
“Good girl. My Noona listens so well♡”
She immediately shot me another rebellious glare.
No matter how hard she tried, it wasn’t scary at all when she was wearing the collar I gave her, anal beads stuffed in her ass, and her mouth stuffed full of my cock.
Perfect timing. I felt like I was about to cum again.
I grabbed her head as she glared at me, forcing her even deeper until I pierced straight through her throat.
Spluuuurt♡! Splurt♡! Gush! Gush! Gush♡!
I pressed down so hard it felt like I was crushing her face, grinding her against my pubic hair and rubbing her face left and right.
I’d cum straight into her stomach instead of her mouth, but that was fine.
Soon enough the semen I’d pumped in would rise back up from her throat.
I’d recently realized just how absurdly much semen I produced.
“Ughk♡! Ubp♡! Uup! Uuuup♡!”
I kept my cock pressed tight against her lips to stop the semen trying to spill out.
Even so, the sticky fluid forced its way between her weak lips.
No matter how roughly I treated her, she never once tried to bite.
She was simply struggling not to lose any of the semen I’d given her.
Because I was shaking her so violently and pulling her head deep between my legs, I could feel the anal beads starting to slip out from between her ass cheeks.
If I’d pushed them all the way in they wouldn’t have come out, but since I’d left part of them visible outside her hole, they slid out if she didn’t clench her sphincter properly.
“Noona, you need to squeeze your ass properly. The anal plug is about to pop out.”
“………”
Her mouth was too full to answer, but she reached behind herself, pushed the escaping anal beads back in, and clenched her ass as I ordered.
“That’s it… Good girl, my Noona.”
“Should we just stay like this until it’s time for you to eat?”
“………”
This was nice. Noona made for an excellent cock warmer.
It felt good and kept me nice and warm.
“…Mmm… Mmmph…”
She would occasionally move her mouth pleasantly, and she didn’t seem particularly bored.
While I browsed the internet, Noona kept playing with my cock inside her mouth, rolling it around.
After keeping it in her mouth for a long time, I felt a new signal coming from my dick.
But it wasn’t the signal to cum. It was something else.
“Noona… I need to piss again…”
“Where should I do it? Your mouth? Your pussy? Your ass?”
See that?
I really am a good little brother who even respects his sister’s opinion.
