11. Hikikomori Park Seo-yoon

,A-ah, no…! Not inside…!

Tteobeok tteobeok tteobeok tteobeok

,Kim, Joon-young, ahn♡ S-stop it! N-no! Not inside, I’ll get, heuk geuk♡ P-pregnant, no! Kim Joon-young-ssi!

Sung Yoo-ah spits out words like a machine gun with a trembling voice.

Tteobeok tteobeok tteobeok

,K-Kim Joon-young-ssi, heung♡ A-ah, don’t cum inside…

Tteobeok tteobeok tteobeok tteobeok

,I’m, a, a subordinate… I, I, ahn♡ I, if I get pregnant, the project pro, gress, geuk, heup♡ Progress, will be, disrupted…!

Tteobeok tteobeok tteobeok tteobeok tteobeok tteobeok

,It’s, definitely not a good, heup♡ G-good choice, it’s, not!

Tteobeok tteobeok tteobeok tteobeok tteobeok tteobeok tteobeok

,P-please… not inside, a-ah, no, please, s-stop, heup♡ Stop, please, K-Kim Joon-young-ssi!

Tteobeok tteobeok tteobeok tteobeok tteobeok tteobeok tteobeok tteobeok tteobeok

,A-ah, no, heeut…♡! Kim Joon-young-ssi! My balls are pulling up, heueung♡ M-my glans is swelling… Pl-please, j-just about to cum, heup, geuk, heungeueungeuk…!

Sung Yoo-ah stops talking and starts writhing in her own climax.

,Ah… Sung Yoo-ah getting pissed about not wanting to get pregnant, that’s so hot…

Even her pussy, scared of the risk of pregnancy, is really tight, squeezing my dick jjoop jjoop.

I kiss her ravenously and press her tightly with my body.

And I increase the speed of my hips.

Tteutbuk! Tteutbuk! Tteutbuk! Tteutbuk! Tteutbuk!

,Jjooreup, hureup, jjeup! Hubeup!

,Heungbeongbeop! Eungeup, kkeup! Heungheung♡ Eung♡! Heung♡! Heungeueukgeungeungeung♡!!

Semen fills the tip of my glans.

Even while writhing in climax, Sung Yoo-ah fiercely resists the fear of pregnancy.

Tteutbuk! Tteutbuk! Tteutbuk! Tteutbuk! Tteutbuk!

,Heungheung♡! Eung, geuk♡ Heubeungeuk…♡

Sung Yoo-ah pushes my shoulder away fiercely.

Whether it’s because of the climax or resistance, she wildly flails her legs.

Sung Yoo-ah’s calves wildly hit the back of my thighs.

But she’s already exhausted from her struggles.

I can feel Sung Yoo-ah’s desperation in the weak but dull blows, which is unbearably hot.

Her body heaves from the climax.

Tteutbuk! Tteutbuk! Tteutbuk! Tteutbuk! Tteutbuk!

,Heutguk, guk, ouguk♡ Oongbeop, beuk, geugeuk…♡

Even though I’m pressing down hard, Sung Yoo-ah’s waist jerks.

My stomach and Sung Yoo-ah’s stomach collide with a smack.

,Oh… shit…!

Her climaxing pussy chews on my dick jjeobeop jjeobeop.

Such a hot situation, and a tight pussy.

The feeling of ejaculation surges.

Tteutbuk! Tteutbuk! Tteutbuk! Tteutbuk! Tteutbuk!

,Hung, ouk, beongbeop…♡

At the moment of ejaculation, I hugged Sung Yoo-ah tightly enough to break her.

,Heungbeongeureup, eung♡! Eunggeuk♡ Heungheungeueueueung♡!!

Byuuuueuuueuk-! Beutjyuuuueuk-!

I pour semen into Sung Yoo-ah’s uterus.

I can feel despair in Sung Yoo-ah’s struggles.

That was really, an unbearably hot side dish.

Byuryuuuueuk, beutjyuuuueuk- byureuk, byureuk-

Stamina enhanced by [So Good For Men].

Ejaculation continues for a long time.

,Jjooreup, oueum… Jjup, hureup…

I sucked Sung Yoo-ah’s tongue even while ejaculating.

At the moment of ejaculation, Sung Yoo-ah’s resistance stopped abruptly.

She’s just writhing in the pleasure that’s washing over her.

,Whoo… haa…!

Sung Yoo-ah’s pussy, giving up on vaginal insemination… so damn tight…

Tteobeok tteobeok…

I start piston action again on the limp Sung Yoo-ah.

,Hoo, heut… Kim Joon-young-ssi.

,Yes.

Her voice is still a little shaky, but.

Her usual coldness has returned.

,Now… please get off… I need to go get a prescription for the morning-after pill, eu, heut♡ T-the morning-after pill.

Tteobeok tteobeok tteobeok tteobeok…

,Since it’s the weekend, the hospital will close, heuk♡, early… Kim Joon-young-ssi?

Tteobeok tteobeok tteobeok…

,K-Kim Joon-young-ssi, stop…

,It’s going to rain starting this evening. Stay over.

,What does that… I came by car. And it’s not evening yet, so if I leave now… hubeum?

,Oueum, jjooreup…

I covered Sung Yoo-ah’s mouth.

She was about to start resisting again, but stopped soon after.

Judging by the way her hand pushing my shoulder is trembling, she seems to be out of strength.

Tteobeok tteobeok tteobeok…

,Oueum, heungeum… Neungeup…

The resigned Sung Yoo-ah started mixing her tongue actively.

Whether she’s tightening her pussy herself, the vaginal walls are gently pressing down on my dick.

She seems to have decided to go in the direction of squeezing out all my semen and getting it over with.

,Oh, is that so.

Wanna try?

I raised my body and held my phone in one hand.

[Would you like to level up the skill ‘So Good For Men’?]

,Yes.

[So Good For Men]

Lv.3

(Always Active Skill)

Sufficient additional buffs are applied to stamina.

From level 1 to level 3.

I threw my phone on the bedside table and kissed Sung Yoo-ah again.

Tteobeok tteobeok tteobeok tteobeok…

,Oueum, heungeum… Jjooreup, hubeum…

,Hureuk, jjeup..

I and Sung Yoo-ah shared a very sticky and viscous kiss to send each other to climax.

She wrapped her legs around my legs and rubbed her breasts against my chest.

,Oh, shit… this is really fucking hot…

Not to be outdone by her powerful physical offensive, I also moved my hips wildly.

+++

The frenzied Saturday passed, and it became Sunday.

,Sseu… My back…

I must have overdone it yesterday.

Before getting the [So Good For Men] skill, I could ejaculate about 2 times at once.

I could squeeze out 3 or 4 times if I pushed myself, but I only felt like ‘I want to do more’ up to 2 times.

When the [So Good For Men] skill was level 1, that number was 5 times.

Yesterday, at level 3, I achieved the feat of ejaculating a whopping 10 times.

Unfortunately, that wasn’t enough to keep Sung Yoo-ah until night.

,I met her in the morning… It was impossible from the start.

It also helped that Sung Yoo-ah, who was getting more and more impatient as time went on, worked her hips hard.

Of course, I told her I had a vasectomy afterward. I can’t tell Sung Yoo-ah about the skill.

I also added that it’s a reversible surgery.

,Sseu…

But after shaking my hips until I ejaculated 10 times, the aftermath is considerable.

Not only my back, but also my shoulders, thighs, abs, etc.

There’s no place that doesn’t hurt because of muscle pain.

,But why does something have to come up today…

A disgusting Sunday surprise additional task.

I was relieved that I could do it at home with my laptop, but.

It just so happened that it was a task that required the USB I had lent to Park Young-min a while ago.

Inevitably, I dragged my aching body and set off for Park Young-min’s house.

,Still… I’m glad he had it in his bag. What would I have done if I had to go to the company?

A 15-minute drive. I arrived at Park Young-min’s house.

An apartment that’s only 2 years old.

It’s an apartment aimed at middle-class people with some money, and it was built recently, so it exudes luxury.

When I rang the doorbell.

Kkieeek-

,You’re having a hard time.

Park Young-min, who had heard the situation over the phone, opened the door.

Park Young-min looks at me sadly.

,Where’s your family?

,I only have my older sister, but she doesn’t come out of her room. Have a cup of tea before you go.

I passed the shoe rack and entered the house.

,If it’s his older sister…

It’s that unemployed older sister who often comes up in conversation.

,At this point… taking care of one unemployed person can’t be a big deal, right?

It’s not luxurious, but the scenery that catches my eye gives me a sense of affluence and leisure.

Not rich, but a sufficiently successful middle-aged couple’s house. That’s exactly the feeling.

,It’s expensive.

He brought out chocolates as refreshments.

But what’s funny is that he brought beer as a drink. Mango-flavored beer.

What kind of nonsensical combination is this?

,You said have tea. Alcohol from the morning?

,Is this alcohol? It’s a drink, a drink. There’s nothing else really.

I emptied the can and talked with Park Young-min.

How many minutes had passed? Almost one can was emptied.

At that time.

Kkieeek-

The door opened and a person walked out into the kitchen.

Park Young-min, who was a little drunk, didn’t seem to hear it.

,It must be his older sister.

I was about to get up from my seat to greet her.

But I couldn’t get up and ended up freezing in an awkward posture.

Because Park Young-min’s older sister’s outfit was very unconventional.

,Milk…

She’s rubbing her bleary eyes, stumbling as if she just woke up.

,She has really dark circles under her eyes.

Her eyes look a little gloomy, with a decadent beauty.

,Her clothes…

Just panties and a tank top.

Interestingly, the panties are men’s spandex briefs.

The thin white tank top is clinging to her body, and she’s even braless.

The tips of her C-cup breasts, which are bulging, are protruding.

The protruding part is quite wide for nipples.

,Is it a protruding areola?

The fabric is thin, so the color inside is clearly visible.

Pink.

Both her nipples and areolas are light pink.

,Wow… crazy, what an ass…

An enormous pelvic width.

Even if I hugged her tightly with both arms, I wouldn’t be able to hug that pelvis completely.

And thick thighs that continue below that.

The end of the spandex panties’ leg part is deeply digging into her thighs, which visualizes the thighs’ firm texture.

,How does she get that shine…? What did she put on?

She doesn’t feel fat at all.

Those are really the luscious, chewy, and firm thighs that men can’t help but like.

,Oh, shit… that’s…

The seam in the center of her panties is digging very deeply between her pussy, revealing the thick outline of her pussy lips.

It’s a very clear cameltoe.

,This is really crazy.

It would be less lewd if she was naked.

At that level, she could probably masturbate by just moving her waist in the air, rubbing the seam against her clitoris.

She didn’t notice my presence and walked slowly with her eyes closed as if she was sleepy, and opened the refrigerator door.

,Uh, uh…!

Park Young-min finally discovered his older sister and was embarrassed by her outfit.

It’s what she usually wears at home, but I’m here now.

,Eueung…

She frowns as she rummages through the refrigerator, not seeing what she’s looking for, and squats down in a peeing position.

,Milk…

Her butt is emphasized because of her posture.

It really looks like her panties are going to burst.

,Wow… I really want to grab and spread those cheeks just once…

I’ve never seen an ass like that in my life.

If I took those off and revealed her snow-white skin, wouldn’t it really look like a full moon?

,Eueung…

Park Young-min couldn’t stand it anymore and opened his mouth.

,……We’re out of milk.

,Huh? We’re out? Jeez… Is it Sunday already?

His older sister yawns and gets up from her seat.

And turns her body towards Park Young-min.

,When you go grocery shopping in the future, don’t just buy 5 cartons of milk, buy 7…

Her eyes met mine.

,……Huh?

,…

Whoa.

I’m breathless.

I’m not the type to be shy around strangers.

But the awkwardness that older sister feels towards me completely freezes the air.

Thanks to that, I’m even awkward, which is unlike me.

But I should still say hello.

,……Hi.

Kwang!

His older sister ran away into her room.

,…

,…

The refrigerator door is still open.

,…

,…

A not-so-short silence flowed.

Park Young-min must be dumbfounded too.

,Where’s the USB?

,…Ah, right. Follow me.

Breaking the silence, I brought up the reason I came here.

I received the USB from Park Young-min.

He cleared his throat for no reason and started talking.

,Ahem. My older sister doesn’t usually wake up this early. So I didn’t tell her that a guest was coming… I’m sorry for showing you such an ugly sight.

,Huh? Ah, it’s okay. I don’t mind.

,I’m glad then.

,…But was that underwear yours earlier?

,…Yeah.

,Why?

,She strangely insists on men’s underwear. She says it’s comfortable. But she gets angry if she wears Dad’s.

I said goodbye to Park Young-min and came out of the house and got into the car, but I couldn’t leave right away.

That luscious ass keeps lingering in my head.

,…

I put a cigarette in my mouth and lit it.

,It looks really delicious… but still, this isn’t right.

She’s a friend’s family.

There are plenty of women in the world anyway, so there’s no need to touch a friend’s family.

,…Still, it’s a shame.

My reason says no, but I keep having lingering feelings.

By the time two cigarettes had burned, I had sorted out my thoughts.

,Let’s not do it.

Geez, me.

I’m dumbfounded.

It wasn’t even a problem to be 고민 about in the first place. It’s something I definitely shouldn’t do.

,Ever since I got the modification app… something’s…

It’s a little strange.

It’s like I’m living too much under the control of my sexual desire.

,I wasn’t this sexually driven before.

I turned the key and started the car.

,A friend’s family is a no-go. Even if I’m not a good guy, I’ll keep the line I need to keep…

[Target: Kim Joon-young]

My vision goes dark.

[Starting modification mode.]

[Modifying the inner self of target Kim Joon-young.]

.

,…?

Ah.

,I dozed off for a moment.

That’s unusual. I’ve almost never dozed off in the driver’s seat.

I was about to start the engine, but it’s already on.

,Ah!

I must have fallen asleep with the engine on.

,How long did I doze off? How much gas is left? I guess there’s enough to go to a nearby gas station?

I checked the gas gauge and thankfully it was almost full.

I must have really dozed off for a short time.

,Phew…

I start the car and get lost in thought.

,Park Young-min’s older sister… hmm… how should I modify her.

She’s a hikikomori with no friends to contact, and she’s unemployed.

She’s living entirely dependent on her parents for living expenses, and she seems to feel burdened by that fact herself.

But due to her social anxiety, she’s holed up at home.

,I need to use these backgrounds.

That way, there will be less backlash and the completeness of the suggestion will be higher.

,If I grab and spread those cheeks… what color will they be?

My balls are already trembling with anticipation.
