I Got into My Childhood Friend's...Yuri Harem?-Chapter 22: Take This, Lightning-Fast Piston!

Brrr.

My penis twitched and throbbed, demanding to be put in another hole.

I wasn’t satisfied yet. I was still hungry.

I pulled my penis out of Kwak Jo-young’s pussy...

...But it wouldn’t budge.

Her pussy was clinging to it, refusing to let go.

I had no choice but to pull it out by force.

I put strength into my lower body, as if pulling out a radish stuck in the ground.

"Ah!"

-Swoosh!

As my penis was pulled out, Kwak Jo-young let out a pained moan.

"Ooh."

Once again, a gaping hole was left where my penis had been.

I felt a sense of accomplishment.

"I could fit my fist in there."

As I admired Kwak Jo-young’s pussy, now a gaping cavern instead of a virgin’s tight entrance, Seong Ji-min approached and gave another order.

"Before you put it in, you know what to do, right?"

She looked down at my flushed penis.

It was steaming from the intense friction.

A mixture of semen and vaginal fluids, giving off a strong lewd smell.

It seemed Seong Ji-min wanted Kwak Jo-young to clean it with her mouth.

"Seriously?"

"You have to establish the rules from the beginning. So the other girls can learn."

"Hmm."

Kwak Jo-young was Seong Ji-min’s lover. And this relationship was consensual between them.

There was no need for me to interfere. If that’s what Seong Ji-min wanted, then so be it.

And it was a good deal for me. There was no reason to refuse.

"Hah... hah... hah..."

"Hey."

Kwak Jo-young was panting, exhausted from her intense first experience.

I offered my soaked penis to her.

"Suck it."

She lifted her head with difficulty and looked at my penis.

Her tired eyes widened in shock.

"Th-This?"

"Why? Is it dirty?"

"O-Of course..."

A predictable response.

It was natural for her to be disgusted.

But I had a card that could break that common sense.

I activated my trap card: Seong Ji-min.

"So, you want me to make Seong Ji-min clean up your mess?"

"Aww, no~"

Seong Ji-min uncharacteristically acted cute, as if hoping I would object.

I ignored her and ordered Kwak Jo-young,

"Clean it with your mouth. Seong Ji-min is next. I can’t put something so dirty inside her, can I?"

Seong Ji-min put her arm around my shoulder and chimed in,

"That’s right. I’m next, Jo-young. Then we can truly become sisters, right?"

"O-Okay..."

Kwak Jo-young, who had been listening to me with a bewildered expression, nodded automatically at Seong Ji-min’s words.

Does this girl seriously have a hypnosis app or something?

Then Kwak Jo-young sat up and started licking my penis.

As if meticulously cleaning a baton to pass on to her friend.

"Mmm, chup, haa, chup, slurp, mm. Haa..."

She diligently suckd mu cock, despite her exhausted state.

What was it that motivated this girl so much?

I stood there, looking down at her.

And Kwak Jo-young looked up at me with fawning eyes.

As if hoping for a word of praise, she moved her tongue diligently.

Tears welled up in her mascara-smudged eyes.

But she didn’t look sad. She was just sincere in her actions.

Instead of praising her, I gave her another order.

"Lick everything around it clean. Not just the penis, but also my balls and thighs."

"Ugh... Okay..."

She obediently followed my arrogant command.

I never would have guessed she’d be so submissive, judging by her appearance.

Fluids from Kwak Jo-young’s pussy had splattered on my thighs and lower abdomen.

She licked them all clean with her tongue.

The inside of my thighs, under my balls, even the pubic hair covering my penis.

As if afraid of missing a spot, Kwak Jo-young cleaned my body meticulously.

"Mmm. Your friend is good at this."

I said to Seong Ji-min, as if impressed by Kwak Jo-young’s diligence.

"Right? She’s my best friend."

Seong Ji-min replied with a shameless smile.

This bastard. One minute she’s saying they’re not friends, and now she’s calling her her best friend?

But Kwak Jo-young looked as if she had been rewarded just by those words.

Her eyes sparkled, and her face was full of life.

She seemed to have forgotten that she had just cried her eyes out after losing her virginity.

Well... I’m glad she’s happy.

As long as she’s happy, even if she’s rolling around in shit, it’s fine, right?

"Okay, that’s enough."

The cleaning was done.

And thanks to her affectionate blowjob, I was rock hard again.

I turned to Seong Ji-min.

She was grinning, looking at my penis.

As if she were looking at a perfectly cooked hotdog.

"Need any foreplay?"

"No. Just put it in."

"Raw?"

"You’re taking responsibility, right?"

"Of course I’m not taking responsibility. You are."

We exchanged light banter as I embraced Seong Ji-min from the front.

"I won’t be defeated like yesterday. I’m not a virgin anymore."

Don’t get cocky, kid.

I’ll show you what I’m made of.

This was Seong Ji-min’s pussy, the one I opened up yesterday.

But now, it had returned to its original, innocent state.

Tightly closed, the entrance was barely visible.

It was amazing that something as big as my penis could fit inside.

I adjused my tip to her entrance.

Somehow, I knew. Seong Ji-min’s pussy was ready, just like my penis.

There’s no visible sign of a pussy being "erect" like a penis.

But I could feel it, through the contact between our genitals, that her pussy was "erect."

"Juji King, your dick is so hot."

"Of course. It’s the dick that’s about to set you on fire."

I chuckled at my own nonsense and pushed my penis against Seong Ji-min’s pussy.

"Ah."

Seong Ji-min stopped laughing.

My thick glans started to pry open her tight entrance.

"Ah... ah? Ah, fuck...!"

Her earlier composure was gone.

Seong Ji-min was flustered, realizing a massive warhead was entering her core.

I, on the other hand, grinned and pushed my penis deeper inside her.

"Huh, huh? Huh? Huh??"

My glans was almost all the way in.

Seong Ji-min gasped, her mouth agape.

Her wide eyes stared at my face.

What is this? Is this real? What’s happening?

That’s what her eyes seemed to be saying.

Even though she experienced it yesterday, she seemed to have forgotten.

The feeling of my penis inside her.

Even though she was shocked and in pain yesterday, she seemed surprised all over again.

"Heh."

I was different from yesterday.

Yesterday, it was my first time, so I just thrust blindly.

Without thinking, driven only by the urge to put my penis inside her pussy.

But now, it was different.

I had experience and patient.

I could now move while considering the other person’s feelings.

I put in effort to truly surprise Seong Ji-min.

At first, I stretched her entrance slowly.

To give her time to mentally prepare herself, thinking this much is okay.

And then, as my penis gradually entered, just as she started to realize something was wrong...

-Thud!

"Kya──!?"

I thrust all the way in, in one go.

My glorious king-sized penis.

So big that she didn’t even have time to register the pain.

"G...uh...uh...?"

Seong Ji-min froze, her eyes wide open.

She reacted similarly to Kim-sunbae yesterday.

Seong Ji-min’s pussy was ready. Ready to accept a penis.

It’s just that my penis was far above a normal penis.

That was all.

"Heh heh. How do you like it? The taste of my dick."

Feeling proud that my plan had worked perfectly, I asked.

Even if Seong Ji-min got angry at my prank, I planned to smooth things over with an apology and a laugh.

But...

"Ugh... uh..."

Seong Ji-min remained frozen, unable to recover.

Strange sounds escaped her open mouth.

"...Huh? Ji-min, are you okay?"

I started to feel uneasy.

Was something wrong?

Did I take the prank too far?

But my worries were unfounded.

"You... bastard, aah..."

Seong Ji-min finally, with great difficulty, managed to speak.

Her head, which had been tilted back, slowly returned to its normal position.

She looked me straight in the face.

A forced smile. The corners of her lips trembled.

A drop of sweat trickled down her temple.

"You... you think you can do this to me... and get away with it...?"

Her tongue seemed to be disobeying her.

Seong Ji-min struggled to speak.

Her words were slurred, as if she were drunk.

The cause was, needless to say, my penis. My penis, buried deep inside her, threatening to crush her womb.

"Pull it out... now... or... else..."

Like someone who can’t breathe after being punched in the gut, Seong Ji-min, hit squarely in her core, was in a similar state. She couldn’t breathe properly, and her words were garbled.

"O-Ooh..."

I felt bad for Seong Ji-min, but...

I was overwhelmed by a tsunami of emotion.

My insignificant plan.

A prank intended to surprise Seong Ji-min, even if it meant getting hit.

But its effect far exceeded my expectations.

Seong Ji-min was completely overwhelmed, even more so than Kim-sunbae yesterday.

Just from a single thrust.

It worked even on Seong Ji-min.

That meant my penis could work on any woman in the world.

"Woohoo-!!"

"Uh?!"

Overcome with emotion, I hugged Seong Ji-min tightly.

And shouted,

The ultimate spell developed by Seong Ji-min herself.

"Take this, you bastard! Lightning-fast piston!"

"W-Wait...?!"
