This Isn't Right, Seon-ah
"Haa..."
That evening, in Seong Mi-na's one-room apartment. Seong Mi-na gulped down her drink in heavy swallows, then set the glass on the table with a dull clunk. She stared blankly at the condensation beading beneath the transparent glass before her mind drifted back to the shocking events of the day.
Her adorable student, Lee Seon-ah, had masturbated right in the middle of the classroom during the exam. Up to that point, she could at least try to understand. But what came next...
The moment she was caught, Lee Seon-ah had spread her thighs wide open, presenting her pussy as if inviting her to look. As though she were happy to be seen by her teacher. She had plunged her index, middle, and ring fingers into that narrow entrance, juices streaming down her hand and dripping onto the floor with wet plops. That obscene sight...
No matter how many times she replayed it, it didn't match the Lee Seon-ah that Seong Mi-na knew.
...I should have stopped her.
When Lee Seon-ah first shoved her fingers into that place... No, even earlier, when Cha Eun-jung had been touching her in the classroom. If only she had intervened then. If she hadn't hesitated and had bravely pulled Seon-ah away. If she had embraced her warmly and guided her back to the proper path...
Would things have turned out differently?
Seong Mi-na rubbed her throbbing temples and filled her glass to the brim once more.
"Huu..."
The emptied glass returned to the table as a heavy, liquor-scented sigh scattered into the air. As she continued drinking, a small question suddenly surfaced in Seong Mi-na's mind.
As a teacher, she knew very well how easily even the most diligent students could stray. Yet the extent of this transformation in the short span between summer break and midterms simply didn't add up, no matter how she examined it against her years of experience.
There was, however, one possibility that made sense.
...That she had been that kind of girl from the very beginning.
Slap— The cheek she struck flushed bright red.
What kind of thoughts was she entertaining about her own student? Had she lost her mind?
Scolding herself again, Seong Mi-na refilled the empty glass. But the alcohol only made the questions multiply, each one feeding the next until they swelled out of control.
...Yet if she looked at it that way, everything fit perfectly. After break, the girl had started wearing her uniform in an outrageously provocative manner. She sat on her friend's lap, visibly delighted as that place was touched. Today she had even masturbated in the middle of an exam.
Could such a lewd child have been the same perfectly proper, studious girl from just a few months ago? The one who would blush scarlet at the mere prospect of the teacher taking her hand?
...No. That was impossible.
"...Seon-ah, you were the bad one. Weren't you?"
Her eyes, already flushed from drink, grew misty.
"Pretending to be a good student while hiding what a naughty girl you really were... deceiving your teacher..."
A sticky tangle of emotions swirled inside Seong Mi-na. Guilt for failing to prevent her student's corruption. The sense of betrayal from someone she had trusted deeply. And...
"Huup..."
Self-loathing for the way her body had grown sexually aroused watching that very student.
Seong Mi-na slipped her hand into her damp panties and stroked her soaked pussy.
Just thinking about Seon-ah made me this wet...
Too afraid to insert her fingers, she caressed her clit with the same light, careful touches she always used. The masturbation continued until her guilt finally dissolved beneath waves of pleasure.
Second day of midterms. Morning. The academy staff room.
"Mi-na, are you sure you're not sick? Those dark circles under your eyes..."
"I-I'm fine...!"
The memory of the previous night flashed through her mind. Seong Mi-na's face burned scarlet as she frantically gathered the test papers and fled the staff room before anyone could stop her.
...Pull yourself together, Seong Mi-na.
After whispering the words to steady herself, she forced her strangely leaden feet to carry her toward the classroom.
What if... Seon-ah is masturbating again?
But her fears proved groundless. The classroom was just as peaceful as the day before. The girl in question was diligently reading her notes this time...
Seong Mi-na let out a silent sigh of relief.
Yes. Yesterday must have been a dream. ...I'll think of it that way.
And so the second day of midterms began.
"..."
The classroom hummed with the sound of pens scratching across paper. A perfectly ordinary testing atmosphere. Yet Seong Mi-na couldn't stop fidgeting, her gaze repeatedly drifting toward Lee Seon-ah.
"Mmm..."
The girl had been making those soft, pained noises while working on the problems for some time now.
Both hands are on the desk, so she can't be... masturbating. Maybe she's feeling unwell?
Worried, Seong Mi-na finally walked over to her.
As she approached cautiously, Lee Seon-ah lifted her flushed face. Up close, the girl's complexion looked strained and feverish.
Seong Mi-na leaned down slightly beside her, careful not to let the other students overhear.
"Seon-ah, are you feeling sick? If it's bad, you should go to the infirmary..."
"Yes.... Teacher, it hurts here."
"...?"
Lee Seon-ah pressed her lips to Seong Mi-na's ear and whispered in a languid, breathy voice. Then she took the teacher's hand and guided it downward. The destination was...
Beneath Lee Seon-ah's skirt.
"S-stop..."
Seong Mi-na tried to pull her hand away, but with students taking an exam she couldn't cause a scene. Helplessly, she let the girl lead her fingers.
"Huuung..."
W-what do I do...! I-it's really touching it...
Her fingers, slick with nervous sweat, met something far wetter. Lee Seon-ah's pussy was drenched. Terrified that any wrong movement would make her a teacher who had molested her student, Seong Mi-na froze with her hand outstretched.
But then...
Huh? It feels like something's vibrating...
"Teacher.... Um..."
Lee Seon-ah's voice slipped into her ear just as Seong Mi-na was trying to identify the source of the tremors.
"It's too painful... deep inside..."
At the same time, Lee Seon-ah gathered the teacher's middle and ring fingers and pushed them straight into her own pussy.
"Huuuup...♡"
"...!"
Seong Mi-na had unintentionally buried her fingers inside her student's pussy. The realization that she was doing this to her pupil—and during an exam—sent her spiraling into panic, but...
Oh god...! I-it really went in.... Seon-ah's... wait?
She felt something hard against her fingertips.
There's something inside...? Plastic? And it's vibrating...
Without thinking, Seong Mi-na stroked the object curiously until its identity suddenly dawned on her.
This is... no way...
"The rotor feels good enough, haa... but it's not nearly enough to soothe my pussy properly..."
Lee Seon-ah's heated voice was turning into desperate pants.
"But now that Teacher is... helping me like this..."
"T-this isn't right, Seon-ah..."
Seong Mi-na tried to stop the girl from crossing any further lines, yet her mind remained fixated on the fingers buried inside that tight heat.
Seon-ah's place... it's so hot and slippery. And it's squeezing so tightly...
The feverish inner walls sucked wetly at her fingers, coating them in thick, sticky nectar. Her student's lewd pussy felt like a female spider trying to devour its prey. Simply feeling that texture awakened a strange, burning thirst inside her.
No... I have to stop before I become strange too...
"Teacher is right. ...This isn't right."
"S-see? So..."
The moment relief flickered in Seong Mi-na's eyes, the student who had betrayed her teacher's wishes spoke again.
"Instead of staying still, you need to move."
Using the teacher's fingers, she began vigorously rubbing her own inner walls.
"I need you to quickly, huup♡ soothe this horny pussy...♡"
Seong Mi-na's fingers plunged in and out of the dripping hole at a rapid pace. When they sank deep, the softened vaginal walls clung tightly, begging for more. When they withdrew, the same walls sucked greedily, refusing to let them escape.
Even though this was the first time Lee Seon-ah's pussy had ever welcomed fingers, it greeted them with shameless coquetry, like a lewd newlywed welcoming her long-awaited husband.
"Teacher's fingers... they're so long... rubbing all my favorite spots inside... so much♡"
The student's obscene voice, the voice of a bitch drunk on pleasure, kept echoing in Seong Mi-na's ears.
Little by little...
"Huu, huuu..."
With a dazed expression and heavy breaths, Seong Mi-na felt herself slowly being corrupted by Lee Seon-ah.
Then she noticed the other students watching them with flushed cheeks, stealing glances.
"Eep... I-it's nothing! Just focus on your tests..."
Even as she spoke words she herself couldn't believe, Seong Mi-na remained trapped beside the girl until Lee Seon-ah's pussy convulsed and trembled in climax.
But Seong Mi-na didn't know.
That to Lee Seon-ah, this was truly nothing special. And that tomorrow would be...
