Day 992
Ugh... It's coming out...!
[SYSTEM: CUM ORAL +1]
In the end, my guess was spot on.
Mmmph! Uhm, tsk, mmm...
If the act of just ejaculating at all is allowed, then most of it should be fine.
Over the past few days, I've confirmed so much.
Whether it lands on her ass or splatters all over her face.
As long as it's a system-defined "owned slave," any ejaculation should convert to points.
There are exceptions, though.
If it lands on her photos or you just pull out and cum into thin air in front of her, it doesn't count as points.
Must require direct physical contact.
Semen has to actually touch her mucous membranes or skin.
Puhut, tsk, keh, kehh... gak.
Don't spill it. Swallow every last drop.
... tsk... uhm, churuk... tsu, mmm...
Her throat must have caught on the sticky semen.
My little sister is coughing nonstop while my cock is still buried in her mouth.
But when I grab the back of her head and press her down, she keeps going anyway.
Her wet tongue gently strokes my sensitive head.
Right after I came, the oddly ticklish sensation feels stronger than the sharp pleasure.
Forgot again? You don't remember what I said to do, do you?
Ugh, uuuun... chuuuhup, tsk...
... Yeah. Swallow every bit that's still inside, too.
Why? You can do it, but you're acting like this.
My sister purses her lips in a cute O-shape and sucks my cock like a straw.
The semen I couldn't pull out stays deep inside, and the weird feeling of being sucked out makes my toes curl up in pleasure.
At first it was painful because I had no technique, but my sister has found the right pressure in just a few days.
If you forget again... you'll remember, won't you?
Churuk, chuuhup...
Ah... it feels good...
We've only been doing this for a little while, so she's still clumsy.
But compared to before, it's a huge improvement.
At first she was terrified even of touching my cock with her tongue.
She gagged nonstop from the smell of my pre-cum and her head twitched like a wooden stick.
She hasn't become noticeably skilled yet, but the fact that she's improving is what matters.
She can at least sweep her lips along my shaft with a few shaky nods, and she's managed to take half of my cock into her mouth.
She's clearly struggling, but my sister now swallows every drop of semen I spit without any hesitation.
What's next?
Well, she's improved, but that doesn't mean I'm super satisfied.
It's not completely comfortable.
She keeps forgetting the next step and the flow breaks every few minutes.
I'm too stupid to focus on one thing without forgetting the rest, so I have to remind her constantly.
Churuup, pppk.
After my scolding, my sister sucks the tip of my cock hard before pulling off.
A light pop as air escapes.
With a familiar slap and friction sound, she grabs my cock with one hand and starts gently stroking it.
The saliva in her mouth has soaked my shaft, so it slides smoothly without any stiffness.
This is just to keep the sensitivity going even after I came.
I haven't forgotten that part.
C-clean...
Say it again. Clearly.
My sister hesitates, then lowers her eyes in fear and mutters.
... C-cleaning... I-I am.
I slowly stroke her soft hair in approval.
Using your mouth for a long time is surprisingly hard labor.
Plus, there's the humiliating fact that it's my little sister's cock in your mouth.
Is that why her neck is bright red all the way down?
Uuuu...
Between my cock shaft and balls.
The smell of mixed saliva, pre-cum, and semen is thick and pungent.
Even from my nose it stings.
My sister stares at that valley hesitantly, then closes her eyes in resignation and sticks out her tongue.
Haap, tsuup, chwururup, tsk.
Suck harder.
Uuun. Tsuup.
I press her face all the way into my crotch.
My sister's rough tongue pushes up from below to rub my cock base.
It moves back and forth like scraping leftover residue, and her hand holds my shaft steady without tilting it.
Her lips press against me like kissing a thick piece of meat, while the bumpy texture on her tongue drives me wild.
In reality, it's just the same as coating with saliva.
But the feeling is good, so it counts.
While I watch my sister's selfless service, I pick up my phone.
Time check... not much left.
Still, I can do it one more time.
Hey, I have to go out soon.
I tap my sister's head while she's lying down.
Open your mouth again.
... tsk, u-uhm...
My sister obediently opens her mouth like a trained animal.
You know what's missing, right?
S-sorry...
This time, don't fail.
... Okay.
Try it.
My sister puts both hands on my thighs, then takes my cock deep into her mouth.
Uuhp, ugh, uuuhup...!
My cock crushes her soft lips as it goes in.
Her mouth is way hotter and sloppier than the outside air.
The hard roof of her mouth feels like a washboard on the tip, and her soft tongue wraps around the bottom of the shaft.
Halfway in...
Ker, gak.
My sister spits out the saliva pooling in her mouth and twists her face.
Hey.
Keh-ugh, ek, uek...
Be careful not to let your teeth touch.
... uhm, uhm...
My cock is 14 cm.
The average Korean man is 12 to 13 cm.
I'm a little bigger.
The stats on the internet might be unreliable, but I know the saying "ignorance is bliss."
At least I believe I'm above average, so my mental health stays fine.
I don't mind being the big one in adult videos, either.
Uuhp, kup.
Even so, my sister's appearance while forcing her mouth open to take it is a mess.
I give her a light warning.
You know? If my sister can't, I'll do it?
... U-uh...
My sister's face, already flushed with shame, turns deathly pale.
It's a good view seeing two completely different colors on her face.
She wouldn't misunderstand.
She's being told to use her mouth like an onahole and fuck my cock without stopping.
I've done it several times already.
The memory of her throat being slammed while I force it in is strong.
My sister trembles and desperately moves her throat up and down.
The sound is like her neck is choking because she only opens and moves her mouth.
Kek, gak, ek, kkuk...
My sister is struggling.
She's kneeling in front of me while I lie down, and the motion is exhausting.
She's never exercised a day in her life.
Even if it's not intense, her breath will run out soon.
My sister's hands unconsciously slide toward my balls.
Not to hold my cock, but to cry and struggle to ease the neck pressure.
... Hey. Don't use your hands.
Uhm...
My cold voice.
My sister freezes and puts her hands back.
Ten minutes left.
Churuk, gehak, kup, kuk, tsu, uhm...! Hek... chuep!
Actually thirty minutes left, but forcing myself into a desperate limit makes results better.
I'm already buried between her legs, so she doesn't know how much time has passed.
Uuhp, tsk, tsk, kurk...
Ten minutes feels plenty, but right after I came and she's clumsy, it might feel too short.
She's never come from oral before.
My sister coughs like she wants to vomit, drools, and forces a pained face while trying.
It's getting better little by little.
Kak, chwurup, tsueut, tsuubup, tsuu!
Good. Keep doing that.
Even when I praise her, she sucks desperately.
Huuu...
My crotch is empty, but why does it feel so good?
I stay lying down, use my arm as a pillow under my head, and start the pre-loaded video on my phone.
Heuhp, churuk, kimoochi? Maida ikanai ne.
I can't hold it, so I'm giving you a good one.
Huuuhp... chuep...
Watching another person suck while I watch is the best.
The feeling is great.
Even though my sister is a bit plain and chubby, she's still a woman.
As I watch the video and get real-time service, the visual and touch combine until I almost feel like the actress in the screen is sucking me.
You don't just move fast and get pleasure.
Kuk, gup, gehak...!
... Not too fast, sometimes just suck the tip with your tongue too.
... Tzulup, chuuhup, tsu, uun, churuk...
Yeah, lick like you're circling. As if teasing the urethral hole in the middle... ah, that one.
That feels good.
Hurup, tsuu, chup...
Put it deep in your mouth again and suck.
Kkuuhup, gek, kuk, kak, eeeup...!
Do that over and over.
I give my sister instructions between my legs to match the video's angle and speed.
Even if she doesn't copy perfectly, her desperate imitation sounds pretty good.
Now that's satisfying.
Uuhup, chuuhup, churuk, tsuu, kehak, kipkip, tsuryurung...
Haaaa...
Oral sex is a direct act.
I really love fellatio.
The visual of a woman serving a man one-sidedly is stimulating, and watching the humiliation makes me feel both perverted and dominant.
It might be a twisted compensation for not being able to talk to women.
It also has the advantage of being easy.
I'm not the type who says sweet things, and sex as high-intensity exercise isn't easy.
Fellatio lets me stay still.
There's a position of dominance, but if I lie on my sister, the pleasure won't be there and my waist will hurt first.
After I took my sister's virginity, using her mouth as a toy was natural.
I had an excuse to experiment, but the real reason was my own stubbornness.
Five minutes left.
U-uhgep... tsu, tsu! Kuk, uuup!
But the feeling was disappointment.
In countless videos, actresses easily milk semen from their mouths, but the wall between fantasy and reality is high.
My sister isn't one of those actresses.
Now thinking about it, I was too optimistic.
The mouth gives direct pleasure, but it's limited.
There's no tight squeezing from all around like inside the vagina.
The mouth itself is empty, so it's hollow.
The only place to apply pressure is her pursed lips, and even that can hurt if your teeth touch.
Just sucking takes skill.
Just creating suction only makes the dick a vacuum.
That's not enough to reach the orgasm feeling.
Too hard and it hurts.
The most stimulating part is rubbing the shaft with her flexible tongue or licking the head, but that's all it amounts to.
Deepthroat is different, but my sister doesn't have the skill yet.
From what I've researched, fellatio is more about the psychological feeling during the act than direct stimulation.
The video often shows the guy finishing by fucking her mouth.
Anyway, my sister isn't at pro level.
Even if I say she's pretty, there's no lust or dominance to come out.
It's not lust, it's just service.
As a last resort, I use my hands while she uses her mouth, or I fuck her pussy hard before cumming in her mouth at the end.
But...
It's not enough.
No satisfaction.
Since we're doing it, we should do it right.
Churup, churuk, tsuu. Kek...
So for the past few days...
I've been "educating" my sister.
Even if it's not vaginal, since it doesn't affect point gain, there's no problem.
Three minutes.
Eh, euh, uuuu...
Time keeps passing.
... Chuuup, kuk, gek, uuhup, churup...!
It's still far.
Plenty of time.
... Kek, heek, huhup! Churup, tsuup, chuep!
My sister must be desperate, so tears gather while she slams her throat, licks, and moves up and down.
But it's been a long time using her mouth.
My sister looks exhausted.
From above, she looks completely sluggish.
One minute.
Eh, u-uh... s-sorry, I-I...
Time's up.
As expected, my sister's beginner skill isn't enough.
I toss the phone aside and sit up.
I-I'll try harder next time...
Open your mouth.
T-that... ah... uh...
My sister looks up at me pitifully, but I gently press my erect cock against her nose and lips.
I have to go to work.
How am I supposed to work like this?
... A-uh...
Quickly.
......
My silent pressure makes my sister clench her fist.
She realizes she can't resist and closes her eyes, then looks up with despair.
... Ah.
You know? I gave you a lot of time.
......
Next time, do better.
She softly rubs my cock against her soft tongue, then firmly grabs the back of her head.
Uuhup! Ugeehak!
I push my hips deep.
... Huu. Eventually I'll have to use my throat too, right?
Guruk, gehak, garrubung...!
My sister's hands grab my legs in sudden stimulation.
She weakly pounds with her free hand, lost.
She couldn't push me away, so it was just weak resistance.
Don't forget that later you'll have to suck properly and use your throat.
Gup, kak, kurk, ugeup...
Don't throw up.
Then I'll go.
I pull back once.
Then thrust forward using the recoil.
Tsupuk.
The bubbling saliva in my sister's mouth acts as lubricant as I push in, and the sticky sound and friction echo loudly in her narrow mouth.
Ueeehak, kuk...
One more time.
Jik.
Endure.
Kuruhup!
Jik.
Gek! Kak!
Jik. Jik.
U-uhm, uuhup, uuhup!
She couldn't hold it anymore.
Uuhup...! Kek, kek, uek! Haak, ha, haak, uuu...
Unable to hold back the rising vomit, my sister wriggles free and turns her head.
My sister on the floor with her mouth out violently gags.
Fortunately, only long strings of saliva fall.
She did throw up once before.
Since my sister cleans it, I don't care.
... Ah. You're messing with me?
S-sorry, uuuhp... sorry, sorry...
Again.
I-I... S-Seojin... P-please... please forgive me... I'll do it better, so... uhm...?
Tears, snot, and sweat.
My sister's teary face begs.
Ah, fuck.
My sister's body stiffens at my curse.
I look at her frozen expression.
I have to go to work.
Are you trying to make me angry?
......
I said it.
If you can't, then clean up my little sister's sexual desires neatly.
What else can I do?
Actually, this is much harder than licking or sucking.
But it's not my job.
......
If you're late, my sister will take responsibility?
......
Open your mouth again.
... Uuh...
See?
... Ah.
My sister opens her mouth again.
She's supposed to open it as I said, but why is she stubbornly holding back?
This time, I'll do it without stopping.
I'm really in a hurry.
Ah, okay...
Just like before, do it again.
......
No answer.
So I thrust again.
Huuk, hek, hek...! More, more! Not touching teeth!
I manage to cum in my sister's mouth.
Ugep, gehak, geeuh, kukku! Euh...! Kkururuk...
... I'm going...!
