Episode 5. It's Only Natural
Episode 5. It's Only Natural
"......"
For a moment, the surroundings fell silent.
It was as if the sound of applause had absorbed all the surrounding voices and vanished.
Seyeon looked at Yubin once more.
She was standing stiffly like a mannequin, staring blankly straight ahead.
"You should have come in with me when I told you to."
Only then did Seyeon's voice soften as she gently took hold of Yubin's wrist.
"Let's go, Yubin-ah."
"Mm......"
Yubin answered in a voice that sounded as if she were still half-asleep.
Thump, thump......
As they entered the bathroom, the sound of the two girls' footsteps rose from the floor and echoed repeatedly, as if they were walking through a deep tunnel.
"Wow, it's really dark in here."
Seyeon said with a sly laugh.
It was so dark that anyone not accustomed to the darkness like Seyeon would surely have bumped their head or foot or something somewhere.
Yubin, who had entered a near-sleepwalking state, just walked along as Seyeon pulled her, staring blankly ahead with glazed eyes like a sleepwalker.
"Here, this way......"
Seyeon said as she opened the door to the stall at the very end of the bathroom.
Creeeeak......
The door opened slowly with an unpleasant sound, as if poking directly at one's nerves.
"It's clean enough."
Seyeon glanced at the toilet and spoke to Yubin.
"Sit."
The temperature of her voice had changed, sinking into coldness. It was a tone and manner of speaking close to an order.
Yubin nodded and plopped down onto the toilet seat as Seyeon instructed.
Seyeon confirmed that Yubin was seated properly and then locked the door handle.
Creeeeak-
Click.
In that instant, the two were isolated from the world.
Seyeon looked at Yubin again.
Sitting on the toilet, Yubin had her head bowed deeply, her disheveled hair drooping down like willow branches.
Since it was clear she would drool like a baby again if left like this, Seyeon grabbed a handful of Yubin's hair, twisted it, and pulled it back roughly.
Yubin's condition was better than yesterday.
It felt like she was asleep with her eyes open.
It was thanks to Seyeon adjusting the intensity of the hypnosis appropriately.
Seyeon gently stroked Yubin's pale cheek and spoke.
"Yubin-ah, I'm sorry about yesterday. I should have gone a bit slower."
Seyeon's apology wasn't intended to mock or tease Yubin; it came purely from a genuine feeling of regret.
Indeed, even Seyeon thought she had been too reckless yesterday.
Like a child who had gotten their hands on a desired toy, she had been in a hurry to just play with it.
Seyeon's taste was far from speed.
Rather, she wanted to take her time meticulously, developing things slowly and thoroughly.
Therefore, trying to stimulate Yubin's vulva yesterday to the point her eyes rolled back was a huge mistake.
Fortunately, she came to her senses and stopped just in time.
But she had almost ruined things due to a momentary impulse.
Seyeon thought of pleasure and orgasm as being like dominoes.
If you set the blocks up short, it would take less time, but the moment they fall—the moment of orgasm—ends quickly.
But if you are not impatient and invest enough effort to set up the dominoes long and tall... then the pleasure will last longer, and the number of falling blocks will be greater.
Seyeon sincerely believed it would be a great misfortune for both Yubin and herself if Yubin couldn't experience the latter kind of pleasure.
To achieve that, I must thoroughly control and manage this girl.
Seyeon resolved herself.
And that apology just now was her reaffirming that resolution.
"Let's take it step by step, Yubin-ah?"
"Mmm......"
"You answer so well, what a good girl."
Seyeon gently pressed her lips against Yubin's cheek.
First, let's see how Yubin is doing now.
Since Seyeon had awakened her a bit more than yesterday, Yubin could at least answer or move slightly.
Though it was an unconscious reaction, like the reflex of a leg kicking up when the knee is tapped.
But the subconscious is stronger than the conscious. Seyeon believed that, and it was true from the start.
Which means it's the perfect condition for planting 'suggestions'.
If Yubin is sexually stimulated now, that pleasure will not be easily erased.
If the conscious mind stores memories by writing memos with a pencil, the subconscious carves them into stone.
So they inevitably last longer.
'Where should I start......'
Seyeon thought, but the first part she would start with was already decided.
Namely, the breasts.
"......Euk?!"
As Seyeon placed her hand on Yubin's chest, a short moan escaped Yubin's lips.
"Yubin-ah, your breasts, their shape is really cute and pretty. To the point I wish they were mine."
Even through the blouse, jacket, and bra, the elasticity and softness of her breasts were clearly felt.
"Hoo, hoo, euk, aah......"
"You, your breasts are really sensitive. You don't masturbate by pinching your nipples at home, do you?"
Seyeon said with a scoffing, *pfft*, smile.
"First, it'll be troublesome if you get wet again, so let's take your clothes off."
Seyeon undid Yubin's necktie, took off her jacket, and hung it on the wall.
Next was her underwear.
"You didn't wear stockings today?"
"Uh, no....."
"Hmm? Say it a bit louder."
"I, I don't. Have any left......"
"I see. Hehe......"
Seyeon found it cute how Yubin was desperately answering.
Even though she should be in a dazed, hazy state, as if drugged with sleeping pills.
'Does Yubin-ah subconsciously feel she must answer my questions unconditionally?'
She couldn't know for sure, but thinking so was satisfying for Seyeon.
Anyway, Seyeon slipped her hand under Yubin's skirt, grabbed the side seam of her panties, and slowly pulled them down.
Thus, Yubin's panties ended up dangling from Seyeon's index finger.
"These look the same as yesterday's? They even have a slight sweat smell...... Don't you have any underwear at home?"
"Mm......"
"......?"
The last part was said to tease her, but when Yubin actually answered, Seyeon was instead taken aback.
She really has no underwear?
Seyeon tilted her head.
Hearing that answer, a specific part of Yubin stood out. The jacket and necktie hung on the wall were also slightly worn and faded. So they looked like old clothes.
Even the bra faintly visible through the blouse feels like the one she saw yesterday.
'Is she a bit poor?'
I'll check later, Seyeon thought.
Seyeon skillfully and quickly began unbuttoning the blouse. She could even unbutton things with one hand by now.
The blouse split open, finally revealing the pretty breasts encased in a black bra.
"I'll undo the bra too."
"......Mm."
Swish, click.
In less than a second, the last piece of underwear guarding Yubin's chest fell away futilely.
"Haa......"
A hot breath escaped Seyeon's lips.
Because Yubin's breasts were too perfect.
How could their shape be so beautifully defined? They looked like droplets that would crumble at the slightest touch.
Also, besides her breasts, Yubin's current appearance was incredibly lewd.
Her blouse was half off, she was wearing her skirt but had no panties.
Dressed in such a obscene manner, she was looking at Seyeon with a pitiful, dazed expression.
Seyeon already felt her head throbbing and heating up.
Suppressing the rising impulse, Seyeon grabbed Yubin's breasts with both hands.
"Ugh, ah......"
"It's okay. Let's start with some deep breathing."
Yubin did as Seyeon said.
*Ssuup, haa, haa*—cold air entered Yubin's hot body and exited as warm breath.
Seyeon also matched her timing with Yubin, doing deep breathing together.
Everything must begin after first calming down.
Especially developing sexual sensitivity.
Seyeon first gently stroked the outer area with her index finger. Precisely the part with the Spence's mammary gland.
She planned to start there and slowly move inward, toward the nipple.
Following the round outline of the breast, she lightly scratched along it with her fingernail.
A sensation Yubin had never felt before rushed into her head.
Immediately, goosebumps rose on Yubin's limbs, and an excited moan flowed from her mouth.
"Hheuk, ah, ahhk, haaah......"
"Yubin-ah, your body is too lewd. I'm not even really touching you yet?"
And yet she was making such sweet sounds.
"Mm, uuk, aaaa......"
Seyeon gradually moved her hand inward.
Now it was around the nipple, the areola.
As if drawing a circle, Seyeon moved her finger round and round centered on the nipple. It wasn't weak, but not strong either. It was a motion both soft and rough.
Yubin's reactions began to intensify. With each rotation of Seyeon's finger, her body jolted, *hmm-chk*, trembling faintly, and she unconsciously bit down hard on her lower lip.
"Euk? Ah, kkheuk, ahak?!"
"You're doing well. Don't hold back like that, let your voice out. No one's coming anyway......"
Seyeon repeated several times that no one was coming. It was to plant that notion in Yubin's head.
That way, she could hear all the lewd sounds she wanted.
Tok, tok, todok......
The sound of droplets falling heavily echoed through the bathroom.
It was self-evident what was dripping without needing an explanation.
"Euk, et, aeuk, kkeup, haaaat......"
"Okay, that's enough for here."
Just as when stimulating the mammary gland, Seyeon removed her hand from the areola just before Yubin reached climax.
"Hheuk, heu, hooooo......"
Yubin threw her head back, looking at the ceiling, exhaling short, hot breaths. *Hoo, hoo*.
Sweat droplets streamed down her soft belly, which had no abs, and were absorbed where they met the top of her skirt.
"Yubin-ah, did it feel good?"
"Ugh, ah, heuaaeuk......"
"Eun Yubin, answer."
"Mm, goo, good, hik, goo-d......"
Tok, todok, took......
As if proving Yubin's words, the sound of falling droplets echoed afterward.
With a satisfied smile, Seyeon moved on to the next stage.
Seyeon's finger crept stealthily toward Yubin's nipple.
Then, as if about to grab it gently, she suddenly pinched it firmly.
"Hiiiiik?!"
Pshhht, pshuut-
Jjorrurur......
Yubin's waist bent sharply as her love juice secreted out in an instant.
'Isn't she feeling this too intensely...?'
Seyeon thought sincerely.
Is she talented, or is she just a naturally lewd girl......
But she soon concluded it didn't matter.
Whichever it was, it was fine.
The important thing was that Seyeon had become even more greedy.
From a teacher's perspective, it's normal to feel more motivated when a student shows achievement.
She wanted to turn her into a body that could reach climax from just her nipple brushing against fabric.
Seyeon thought.
To that end, she continued the stimulation blindly.
She poked the nipple, flicked it lightly with her finger, gently kneaded it, then suddenly pinched it hard.
"Hat, aat?, uk, keup, kkyaeueuk?!"
Pshhht, pyubyuuuut-
Overwhelmed by the persistently building pleasure, Yubin's mouth gaped open. Sticky saliva flowed down her chin and dripped, *plop, plop*, onto her chest.
Her straightened legs trembled violently with spasms. Her palms repeatedly clenched and unclenched, and her eyelids fluttered open and shut.
Yubin's current reactions were something that could never appear while awake. Because they arose solely from her hypnotized state.
But the fact she felt it this well also meant she had that much potential.
Therefore, that potential, buried deep in the cold sea depths, must be pulled to the surface.
Her senses must be awakened.
Then, even when conscious, Yubin would be able to cum like crazy.
It was about time.
Seyeon sharply raised her crimson eyes and sharpened her voice to the utmost.
To precisely pierce the most sensitive, smallest parts of the brain.
Seyeon's lips drew so close they almost touched Yubin's ear.
"Eun Yubin, remember clearly. How I'm touching your breasts. How I'm stroking, rubbing, pinching them."
"Eh, heeh? Ugeuk, aheuaat...?"
"Remember which parts are sensitive and which are dull."
Remember.
Remember.
Remember.
Remember.
The word 'remember' spilled from Seyeon's lips. Seyeon's warm breath circled Yubin's earlobe and pushed deep inside, piercing her eardrum, *cook*. It felt as if each word took physical form and physically touched Yubin's ear.
Seyeon now pressed her lips directly against Yubin's ear. Yubin's trembling body jolted even more violently. They could clearly feel each other's heated body temperature. Making them share every sensation and meaning.
When meaning is imbued into syllables, it becomes language. Language moves people's hearts.
Therefore, Seyeon spoke language.
"From now on, Eun Yubin, you become a lewd girl who masturbates with her nipples every single day. You must not skip a day. Before sleep, on the bed— no, wait. You might not have a bed. Lie down on your blanket and carefully knead and fondle your breasts. It's best to turn off all the lights, make it dark. Close your eyes tightly, use earplugs too. Focus all your senses on your breasts. Prepare your brain to fully receive the pleasure. And, while remembering how I touched you today, copy it exactly. Start by gently rubbing the mammary gland area and gradually move inward. Rub the areola up and down, press it firmly, and when you feel your pussy and underwear getting sticky and wet with love juice, then stimulate your nipples. That's the easiest place to feel. If you do it consistently for a few days, later just touching your nipples will make you squirt pussy water and make you cum. But keep touching. Just like I did. Even if your brain feels like it's being marinated in drug-like pleasure and going crazy, never stop. You must cum at least ten times. Understood? It's only natural for a pretty, cute, and lewd girl like you to masturbate like this. Engrave it clearly in your head. It's only natural for you to cum from your nipples. It's only natural. It's only natural because Eun Yubin is a lewd girl."
A 'common sense' was being injected into Yubin's head. Like pouring gasoline *gush gush* into a car's fuel tank.
Wrapped in the suggestion and brainwashing enveloping her brain, Yubin's pupils shook, rolled upwards. Her breathing became even more labored and hotter, like she'd run a marathon.
"Eukeuk, heuk, heeueuk, hik, heuaaaa......"
"And finally, like this, gently pinch the nipple to finish, reaching climax......"
While gently stroking the mammary gland and areola, Seyeon pinched Yubin's nipple softly, not hard.
"Cum, Eun Yubin."
Gguuk-
"Hhiiiiiiik?!"
Pshuut, pyubyuuuut, jjiik, jjiiiiiiik-
Jjorrurururururur.......
A sound like shooting a water gun at the water's surface echoed.
"Whoa, Yubin-ah. You're not peeing, are you? For this much liquid to come out......"
Seyeon pretended to check, glancing down at Yubin's lower half.
Right after cumming, Yubin was sensitive to stimulation, and from just that, she bent her waist and let out another *jjiiik* of transparent, sticky love juice, *pshhht pshhht*.
A pleasure as if her brain was melting eroded deep into Yubin.
Seyeon looked at Yubin.
Her bangs were stuck to her forehead from sweat, her armpits were damp and wet. Her legs were spread wide apart, so her thoroughly soaked privates were openly visible. As if she had suddenly lost half her nervous system, Yubin couldn't support her body and just trembled faintly.
That appearance was so cute and lovable that Seyeon couldn't hold back.
Seyeon climbed on top of Yubin and sat. Then, for a moment, she looked at Yubin with eyes dripping with affection. It was to the point hearts might pop out of her pupils.
"Hooooo, you did well. Yubin-ah. Umm......"
Seyeon's and Yubin's lips met. Their lips were as hot as heated iron.
Seyeon's tongue entwined with Yubin's, sending copious amounts of saliva down Yubin's throat. Like yesterday, Yubin had no choice but to accept it and helplessly gulp down their thick spit.
Accordingly, Seyeon's scent filled Yubin's insides.
"Hup, chuup, jjok, jjook, euhuk, chuoo......"
After ten minutes of deep, sweet kissing, Seyeon finally detached her buttocks from Yubin and stood up.
Then she took out her phone, grinned, and took a selfie with the rear camera. Of course, positioned so Yubin, whose body had gone limp from cumming, was clearly visible.
Both Seyeon and Yubin had copious amounts of saliva smeared below their lips.
The artificial light from the phone's flash created a strange atmosphere.
"Let's say yesterday was a taste... Today marks Day 1. I'm counting on you, Yubin-ah?"
Speaking lines fit for a newly formed couple, Seyeon, while holding both of Yubin's wrists, gently pressed her lips against the girl's cheek.
