Mission: Receive paizuri from your real sister
On Success: Ejaculation volume +50% (When ejaculation volume reaches 200%, daily ejaculation count +1)
On Failure: Ejaculation volume -50%
"Don't overthink it. Your real sister used to take care of you with her hands often, right? It's just that hands are replaced by breasts."
Mephi was right.
Even before becoming an adult, I had crossed a line I shouldn't have with my real sister.
We needed an adult to point out that what we were doing was wrong, but Mom was too busy for that.
After I started dating Arin, I tried to restrain myself.
But today, my noona had tried to cross that line once again.
And Mephi was telling me to take one more step beyond that.
If she even used her breasts, could that still be called a substitute masturbation?
Wouldn't it become quasi-sexual intercourse?
"You look like you have a lot on your mind. Will this give you some courage?"
Mission: Receive paizuri from your real sister in a dream (Modified)
When Mephi waved her hand in the air, part of the hologram window's content changed.
"A dream?"
"I'm going to make Kim Seo-ah dream from now on. And you will enter her dream. It's a piece of cake for a devil. It'll be so much more real than reality that Kim Seo-ah won't even realize she's in a dream."
Mephi took a step closer and whispered like a devil.
"So if you manage to get paizuri from Kim Seo-ah in the dream..."
It means Kim Seo-ah in reality will also give you the exact same paizuri.
"Then what's the difference from receiving paizuri in reality? I'd be crossing the line again anyway."
"A dream is different from reality. Kim Seo-ah will forget that she gave her little brother paizuri. Things experienced in a dream aren't remembered after waking up. It becomes a secret only you remember."
It was truly a sweet trap.
It was so much to my advantage that I almost forgot this was a bet with a devil.
"You'd better accept my goodwill. Remember this well. You only have three chances to refuse. Don't waste them on such a simple bet."
******
Knock knock.
I knocked carefully in front of Seo-ah noona's room.
"Come in or whatever." Noona answered half-heartedly.
When I opened the door and went in, I saw Seo-ah noona lying on the bed.
Noona was wearing only comfortable beige underwear, tapping away at her phone screen.
Seo-ah noona asked without even looking my way.
"You ran away earlier, so why did you come back? Did you change your mind?"
"...Yeah."
"What the fuck."
Seo-ah noona tossed her phone to the side and looked straight at my face.
But soon, a mischievous expression appeared on noona's face.
"But what do I do? I'm not in the mood to do anything dirty with you?"
"Can't I ask you just this once?"
"Then use your own mouth and ask for what you want directly."
"I want noona to give me paizuri."
"...?"
That was an answer Seo-ah noona hadn't expected at all.
Because of that, her reaction came a beat late.
"The fuck did you just say? You want me to give you paizuri?"
Noona definitely understood.
Since noona had a high sex drive.
She watched porn and masturbated.
Unlike my girlfriend, noona knew everything there was to know.
"Why are you suddenly asking for paizuri? Ask your big-chested girlfriend for it, shouldn't you?"
"...I haven't done paizuri with my girlfriend yet."
If you had a girlfriend with big breasts, it was natural to ask her for paizuri.
Especially if that girlfriend would grant any request for me.
But I didn't do that.
No, I couldn't.
I could barely endure it when Arin used her hands, so if I discovered what it felt like with breasts, I wouldn't have the confidence to hold back.
At the mention that I hadn't done it with my girlfriend yet, Seo-ah noona's expression changed.
"Alright, I'll give you the paizuri you want. But I have a condition."
"Condition? What is it?"
"If you endure me giving you a handjob for 3 minutes, I'll let you use my breasts as a reward."
At that moment, the hologram window's content changed.
<First Bet>
Mission: Endure the handjob from your real sister in a dream for 3 minutes.
On Success: Paizuri from real sister & Ejaculation volume +50% (When ejaculation volume reaches 200%, daily ejaculation count +1)
On Failure: Ejaculation volume -50%
I was standing naked in front of Seo-ah noona.
Noona had stripped off my underwear a long time ago.
Noona looked at my half-erect member and smiled as if enjoying herself.
"It's been a while, cutie. Did you miss noona? I wonder if your girlfriend has been treating you right."
Words that shouldn't come from a real sister's mouth reached my ears.
Noona then blew on my member with a "Hoo~".
The guy started getting hard without any self-control, throbbing little by little.
"As sensitive as ever, I see. Getting fully hard even though I haven't even touched you yet."
Seo-ah noona slowly licked her lips with her tongue.
She looked like a female predator that had found some tasty prey.
In reality, my member was nothing but easy prey for Seo-ah noona.
Because noona knew my member as well as my girlfriend did.
While Arin had conquered my member in a short time with her innate talent, Seo-ah noona had years of accumulated experience.
From some point on, I no longer needed to masturbate.
Because my sex-crazed real sister had used my member every day to satisfy her own desires.
That was why 3 minutes was more than enough time for Seo-ah noona.
With my member having premature ejaculation, the probability that I couldn't endure noona's technique was 99%.
But this time, I had to endure it no matter what.
To satisfy Arin with sex, I must not lose even once in the bet with Mephi.
If I couldn't hold it this time, my stamina would be cut in half.
I could already only ejaculate once a day, so I couldn't afford for it to decrease any further.
"Relax. Anyone watching would think I'm going to eat your dick."
Seo-ah noona's hand touched my member.
Noona used her thumb and index finger to pull the skin of my dick.
"Noona will peel back our cutie's skin just like before."
My member, whose foreskin had become completely accustomed to being pulled back from being handled so much by Seo-ah noona.
The problem was that because of its small size, the glans was hardly visible even when erect.
So the skin had to be pulled back directly like this.
Slrrrt...
When Seo-ah noona grabbed the dick skin and pulled, the glans hidden inside was revealed.
Noona immediately brought her nose close and sniffed.
"Sniff... Ugh! Hey, did you not wash your dick today?"
"Yeah. It just happened..."
Now that I thought about it, I had left the motel room this morning without even being able to wash.
Right after that, I had leaked a lot of pre-cum while receiving a thigh job from Mephi.
Since I hadn't washed after coming home either, the inside of the dick skin was bound to smell terrible.
"Crazy bastard. You want your noona to take care of your unwashed dick after fucking your girlfriend?"
Even while saying that, Seo-ah noona didn't stop smelling the dick.
She didn't take her nose off my dick even while frowning.
"Noona, the 3 minutes have started, right?"
"No? I haven't even properly touched you yet, what are you talking about?"
Only then did Seo-ah noona set the time on her phone timer.
"Then shall we see how well our cutie can endure?"
With a beep, the timer's numbers started counting down.
Seo-ah noona targeted my weak point from the very start.
The area just below the glans, which had been covered by the foreskin until moments ago. In other words, the sunken part where smegma easily accumulates.
She slipped that area into a ring made with her fingers and shook it up and down.
At the same time, she spread her other hand wide to cover the top of the glans.
And then she started rubbing it back and forth.
The calluses formed from exercising mercilessly rubbed against the urethral opening.
For a moment, my balls almost lost all their strength.
"My little brother's weak point is right here. You can't even endure when I touch just one of the two spots, so I wonder how long you'll last when I do both at the same time♡"
The two most sensitive parts of a man's dick were being stimulated simultaneously.
I unknowingly tried to pull my hips back, but...
"Where are you trying to run? I won't let you escape easily this time♡"
Seo-ah noona gripped the hand holding my dick tightly so that I couldn't pull it out.
"Noona, slow down a little. It's too intense from the start...!"
"Why should I be considerate? I'm taking care of your smelly, unwashed dick, and you're asking for a lot, aren't you?"
Instead, the speed of the hand stroking the dick only got faster.
It belatedly occurred to me.
That Seo-ah noona's way of touching my dick was completely different from Arin's.
Arin wanted to see what I felt from her caresses.
Since she always put me first, the touch of her hand stroking my dick was very gentle.
But what was important to Seo-ah noona was making me ejaculate.
The very fact that I ejaculated from noona's hand was the most important thing.
Maybe she felt a greater sense of satisfaction the shorter the time it took for me to ejaculate.
That was why she showed no mercy even when giving handjobs.
I checked the phone screen placed on the bed.
Less than a minute had passed.
But my balls were already screaming that they were at their limit.
My member, having grown accustomed to gentle hands, couldn't resist the movement of the hand forcefully extracting semen at all.
"Noona... please..."
"It's okay. Noona will take everything with her hand. This horny dick that came after cheating with another woman♡ Noona will drain it all. So let's just relax and let it out♡"
I couldn't let this happen.
If I ejaculated now, I would lose the bet.
At the same time, my ejaculation volume would be cut in half.
Jjureet-jjureet...! Jjureu-jjureu... jjureut...!
With the help of pre-cum, the hand stroking my dick became even busier.
Seo-ah noona sped up for the final stretch as if she had no intention of going easy at all.
"N-No! I'm coming!"
The strength completely drained from my balls that had been enduring to the limit.
The liberated semen surged rapidly through the urethra.
Just one step before my defeat was confirmed.
Suddenly, noona's fingers that had been wrapped below the glans slid down to the base of the dick.
At the same time, I felt a strong squeezing pressure near the base.
"Ughh!!"
The pleasure of ejaculating was cut off.
At the same time, the semen backed up, turning into extreme agony.
My vision flashed as if I was seeing stars.
As a result, I didn't ejaculate.
A single drop of semen barely leaked out of the urethral opening.
Seo-ah noona picked it up with her finger and popped it into her mouth.
"Mmm, it feels thinner than usual. I guess it's because you did it so much with your girlfriend yesterday?"
Noona put my semen in her mouth and savored it.
It was probably a thoughtless action for noona, but even that sight was overly stimulating to me.
Even now, it felt like I would ejaculate immediately if the pressure of the hand squeezing the base of my dick loosened.
"Hey, Kim Jinsol."
"Yeah, noona."
"Do you really want paizuri that badly?"
"Please let me cum on noona's breasts."
I didn't know anymore.
I had started this for Arin.
Now I just wanted to ejaculate no matter what.
This was already the second time today that my ejaculation had been interrupted without me being able to finish.
This was really the limit.
"Then I'll let you use my breasts."
Beep beep!!
The timer sound signaling the end of 3 minutes.
But maybe it had been meaningless from the start.
Noona could have made me ejaculate within 3 minutes if she had wanted to.
On the other hand, the fact that she didn't make me ejaculate within 3 minutes meant she wanted to give me paizuri.
"Then turn your head away because I need to take off my underwear."
Honestly, I didn't know what the difference was from taking it off right in front of my eyes, but I turned around as noona told me.
I didn't want to miss this precious opportunity.
Sarak... sarak...
I could hear the sound of underwear brushing against skin as it came off.
Was Seo-ah noona feeling embarrassed too?
It took a very long time just to take off one bra.
"You can turn around now."
I turned around the moment Seo-ah noona gave her permission.
But I couldn't see the sight I had been expecting.
Instead of underwear, noona was covering her breasts with her arms.
"Noona, can you move your arms?"
"...Do you really have to look?"
"Then how are you going to give me paizuri?"
Her embarrassed appearance was completely different from the usual Seo-ah noona.
Noona very slowly, as if reluctantly, lowered her arms that were covering her breasts.
Seo-ah noona's breasts were truly beautiful.
A large mass of fat that was rare to see on a woman who exercised.
But the voluptuousness added to her healthy physique was incredibly striking.
"Can I ask your size?"
"...There's no question you won't ask your noona. It's an F-cup."
Even while being tsundere, noona answered my question faithfully.
But there was one thing different about Seo-ah noona's breasts compared to normal ones.
Maybe that was why noona was acting differently than usual right now.
It was the fact that even with her underwear off, her nipples couldn't be seen.
The slightly apricot-tinted pink areolae were visible, but the nipples themselves couldn't be seen.
As if they were shy, they were hidden inward and wouldn't show themselves.
"You're disappointed, right? They're smaller than your girlfriend's, and the... shape of the nipples is weird too."
Seo-ah noona tried to cover her breasts with her arms again.
Before I knew it, my hand reached out and grabbed noona's wrist.
Noona put strength in her arms, but I didn't back down either.
"I've always known your nipples are that shape. It's not like seeing noona naked is anything new."
"Then you must have thought they were hideous all along."
"Hideous? I've never thought that even once."
I carefully stroked Seo-ah noona's inverted nipples.
"I think Seo-ah noona's nipples are pretty enough."
"Really? Prettier than your girlfriend's?"
"...That's hard to compare."
"Can't you at least lie and say they're prettier?"
Noona grumbled. But still, not stopping me from touching her inverted nipples seemed to mean she was secretly enjoying it.
"Touch them gently..."
To hear words asking to be gentle from Seo-ah noona's mouth.
It really must be a dream.
Seo-ah noona's breasts had a completely different texture from Arin's.
Arin's breasts were endlessly soft and cozy.
Like her personality, they were devoted breasts that seemed like they would accept anything.
In contrast, Seo-ah noona's breasts were like bouncy rubber balls full of elasticity.
Even with just a slight pressure, I could feel a subtle resilience.
Unfortunately, noona didn't show any reaction like moaning even when I stroked her breasts.
"How long are you just going to keep touching? You asked for paizuri."
Noona seemed more interested in the act of draining my semen with her breasts.
Seo-ah noona got ready to give me paizuri.
Noona gathered her breasts with both hands.
Then her cleavage pressed together perfectly straight without any gap.
Just before inserting my dick into her breasts, noona warned me.
"Just try moving. If you shake your hips on your own, you're dead."
Having reclaimed the lead, she had reverted to the usual Seo-ah noona.
It was certain now that she wouldn't go easy on me until I ejaculated.
Tsuboot...
With a faint sound, my member was sucked in between noona's breasts.
I heard that people are usually disappointed when they experience paizuri for the first time.
But the paizuri I received from Seo-ah noona was different.
The elastic breasts pressed against my member from all directions.
It felt like real vaginal insertion, enough to call it a tit-pussy.
Noona squeezed her breasts tightly with both hands as if she had no intention of going easy from the start.
"I wonder how disappointed Arin will be. Jinsol's paizuri virginity was stolen by his real sister♡"
I could never ask Arin to do something like this.
I almost ejaculated just from putting it between her breasts.
If Arin found out about paizuri, all the semen I needed to cum inside her pussy would be stolen by the tit-pussy.
"Then let's start the virgin paizuri with my little brother♡"
Jubo-jubo... jubo-bot...
My first paizuri from my real sister.
It was so excellent that it was a shame it was a dream.
Seo-ah noona's gaze looking up at me from below.
The movement of shaking her breasts up and down to make me ejaculate even a little faster.
It was so stimulating that a premature ejaculation dick couldn't endure it.
"How is it? Paizuri that your girlfriend won't give you. How does it feel to receive it from your real sister?"
"It feels so good that it's hard to endure even a second."
"Then you can just cum. How much can you endure anyway? Just spurt~ all your little brother's semen into your real sister's tit-pussy♡ I'll take every last drop♡"
The semen that had risen right below the urethral opening earlier boiled up again.
Perhaps because it had been interrupted twice already, the urge to ejaculate rose faster than ever.
"Pfft. Look at you trying to cum right away just because I said you could. You're not even making a manly attempt to endure a little?"
Ah... it was already too late.
The semen produced by my balls was already rushing through the urethra.
"It's okay even so. Even if you're a hopeless premature ejaculator, Jinsol, I can take it all."
Come on, just cum♡ You cute little dick that couldn't even endure 3 minutes♡ Feel good with your real sister's tit-pussy♡
Tsubut-tsubut... tsubooot...♡
Semen was pushed out at a speed that made it feel like my urethra would burn.
It felt like the maximum amount of semen my balls could produce was being drained out.
Pew! Pyureut!
I finally ejaculated.
I finally released the ejaculation that had been interrupted so many times today.
And on my real sister's breasts at that.
But something felt empty.
Was it because I had experienced an 18cm dick?
At that time, I had been confident I could dye Mephi's thighs completely white with semen.
The ejaculation with my member was over in an instant.
The trace I left on Seo-ah noona's breasts was an amount that could be easily cleaned up with a single tissue.
Post-nut clarity rushed in belatedly.
I had finished alone again this time.
Seo-ah noona would definitely masturbate alone once I left the room.
But there was nothing I could do for noona.
Because I could only ejaculate once a day.
******
After Kim Jinsol left the room.
Kim Seo-ah started masturbating alone, touching her pussy.
Watching that scene, Mephi murmured.
"I didn't expect him to control his ejaculation there. I thought I would win for sure."
But for someone who was disappointed, a smile hung on her face.
A smile that somehow looked a bit dangerous.
"Humans always bring unexpected results after all. This is why I love humans."
When Mephi snapped her fingers, the scene in the room returned to normal.
Kim Seo-ah, who had been masturbating in the dream, was fast asleep in reality.
"Why did you specifically use dreams? With Mephi-nim's ability, you wouldn't need to use such a troublesome method."
Someone's voice asked her.
Judging by the alluring voice, it was definitely a woman.
"What's wrong with dreams? Don't you know that humans discard their masks and become true to their instincts as long as they're given the excuse that it's not reality? Dreams are the best space to confirm that kind of human nature."
Of course, she had no intention of ending it in the dream.
All of this was to see the love between the two lovers fall apart and crash to rock bottom in reality.
But even she, a devil, couldn't be certain.
Because she had created a contract where the possibility of her own defeat existed from the start.
Perhaps she would even lose the final bet and end up offering her body, mind, and soul to Kim Jinsol.
"What would it feel like to become a human's slave?"
She could feel her anorgasmic body slowly heating up.
It was a body that couldn't feel anything no matter what method was used, but at this very moment, it was as fearful and excited as a virgin facing her first time.
"It seems I made the right choice choosing you after all, Jinsol♡ Keep making me enjoy myself more in the future♡"
<Kim Seo-ah's Ero Status>
1. Age: 23 years old
2. Height: 176cm
3. Three sizes: 90-59-95 F-cup
4. Sexual experience:
Hand[99+ times] Mouth[0 times] *Breasts[0→1 times] Pussy[Virgin] Creampie[0 times] Anal[Virgin]
5. Traits:
Inverted Nipples[Kim Seo-ah's complex. She likes it when praised as pretty.]
Brother Complex[Her sexual tendencies were distorted due to not receiving proper guidance in childhood.]
Misandry[A trait developed from growing up in an unfortunate environment. Developed disgust because of men who targeted her and her younger sister's bodies. Her younger brother Kim Jinsol is the only exception. Partially contributed to the development of the Brother Complex trait.]
Masturbation Dependency[Even while maintaining a forbidden relationship with her younger brother, she was never satisfied herself. Naturally came to satisfy her sexual desires through masturbation.]
6. Evaluation: Has such a strong sex drive that she needs to masturbate every single day without exception. Ironically, her body's level of development is remarkably low. It's woefully inadequate to satisfy her overflowing sex drive with only masturbation, but she doesn't realize it. Once she tastes a man's dick, she's highly likely to become unsatisfied with just masturbation. However, since she has extreme disgust toward other men touching her body, developing her seems to be difficult.
