Just like that, the school nurse corrected Subin’s physical grade to the highest level.
“Let’s start the arousal induction.”
Weariness clung to her voice.
Subin answered in a tiny voice, head bowed low.
“Yes….”
I stepped up to her and gently stroked her back.
Subin’s shoulders gave a faint start and trembled.
Somehow she looked different from the other girls.
The others would heat up in anticipation of my touch, but Subin only seemed tense.
“All right, Subin.
Starting the arousal induction.”
I stood beside her as she lay on the bed and first cupped her soft shoulders with both hands.
Then I slid my hands down and took hold of the full, rising mounds of her breasts.
“Hnn….”
A short moan slipped from Subin’s lips.
I savored my childhood friend’s softness at leisure.
When I squeezed, the pliant flesh pushed pleasantly between my fingers.
“Nngh… mm….”
Subin’s reactions were distinctly subtle.
From the moment my hands touched her, she did not gush love juices from her pussy.
She only flushed and held her breath.
Her body responded honestly, yet the response itself was perfectly normal—the kind that did not climax just from a little breast play, the way women had in my previous life.
When I lightly pinched her nipples, Subin finally jerked.
“Ah…!
S-Sihyuk….”
“Shh.
It’s okay.”
I soothed her and gave one nipple a light lick with my tongue.
It was the first nipple I had tasted with my tongue today, and the scent was lovely.
“Hnn, nnngh….”
I moved on, gently rubbing the plump flesh of her outer labia.
“Ah… ah….”
Subin’s pussy was growing wet by degrees.
It was nowhere near the gushing flood the other girls produced, but sticky juices were definitely appearing.
I slowly pushed a finger inside.
The tight yet soft interior accepted me.
The school nurse, watching the monitor, nodded.
“Finally getting a reading.”
Until now every girl had reached arousal so fast that retests had been required.
Only Subin could be measured properly.
On the screen her arousal level climbed in a gentle curve.
“Time to arousal: two minutes thirteen seconds.”
I nodded inwardly with satisfaction.
At last a result within a range I could understand.
Subin, whose climax came slowly, felt more normal to me.
“All right, now bring her to climax.”
At the nurse’s words I slipped my finger back into Subin’s pussy.
When I lightly rubbed her clitoris with the free thumb, Subin’s breathing turned lewd.
“Haa… S-Sihyuk, there… it feels weird….”
“This spot feels good?”
I worked the clit that drew the biggest reaction from her.
The narrow, hot walls tightened around my finger more pleasurably than before.
—Twitch!
“Haaahn…!”
I gently stimulated her vaginal walls, moving my finger slowly.
Subin’s pussy did not explode with sensation.
Instead it heated steadily, progressively.
That process was even more interesting.
“Hnn… S-Sihyuk….
Sorry for making it hard….”
“What’s hard?”
“I… don’t get wet easily… even though you’re the one touching my pussy….”
Her voice grew thick with tears.
I gave a short laugh.
“Not hard at all.
I actually like being able to touch you longer.”
“Nnh, really?”
“Really.
I love it.”
The moment I said I loved it, Subin’s pussy clamped down hard.
She panted for breath.
After maybe three minutes her body arched forward and gave a fine tremor.
“H-hnn, nngh…!”
The school nurse checked the time and recorded it.
“Three minutes twenty-eight seconds total from start of arousal induction.
Climax confirmed.”
I withdrew my finger with satisfaction.
It was not dripping with juices, but wet enough.
I whispered against Subin’s ear.
“Good girl.”
Subin, face still lewd from climax, looked at me with a bright smile and then slipped out past the curtain.
Watching her leave, I decided I would have to ask later what HSDD actually was.
While the school nurse sorted the girls’ records, my erection gradually subsided.
“All right, Class President Kim Sihyuk’s turn.”
I nodded at her words.
I would have to strip too, right?
As I started to undress, the nurse casually turned to leave the curtained area as if it were the most natural thing in the world.
“Where are you going?”
“Ah, with men we usually measure alone.
Having a woman nearby can make them uncomfortable.”
She spoke as if it were nothing, but I did not miss the flicker of regret in her eyes.
I studied her carefully.
The name tag around her neck read Lee Seoyeon.
Around thirty, with a quietly pretty face.
In a boys’ high school she would have been the subject of endless dirty talk.
The figure beneath the white coat was full of curves.
Especially the legs extending from her neat skirt, sheathed in black stockings that radiated a quiet sensuality.
She was the classic image of the pretty school nurse every guy had fantasized about at least once.
“Teacher.”
At my call she stopped and turned.
“Would you help me?”
The school nurse’s eyes went round as a rabbit’s.
Clear fluster.
“…What?”
I smiled as if it were the most natural request in the world.
“I don’t really know how to measure it by myself.”
She looked flustered, yet the corner of her mouth twitched of its own accord.
Expecting the sight of my naked body, she came back with trembling steps.
“W-what do you need help with…?”
“Everything.”
