The School Nurse's Titjob Blowjob
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."
I smiled and pulled off my top. When my solid upper body appeared, her gaze lingered for a moment on my abs. Ignoring that, I undid my belt. My still-soft cock came into view.
"Th-then… length first…."
The school nurse picked up the measuring tape with shaking hands. As she drew near, a faint perfume brushed my nose—strangely arousing. I stood still and waited for her to measure.
The cold tape touched my cock. She moved carefully, trying not to touch my body more than necessary. Even so, tension traveled through every unavoidable brush of her fingers.
"Pre-erection cock size…."
When her fingers touched my shaft I could not help a soft exhale. Soft, warm contact. A slight slickness, as if she had used hand cream.
"Twelve centimeters…."
Her voice shrank. Next was girth. When she wrapped the tape around the shaft, my cock twitched in response.
"Ah…!"
She nearly dropped the tape in surprise. Enjoying the reaction, I deliberately tensed my lower abdomen. Blood rushed in and my cock began to swell.
"H-hey, Sihyuk. You can't get hard yet…."
"Can't help it. Teacher's hands are too sexy."
At my shameless answer her face flushed as if it might burst. In no time my cock stood fully erect. After a brief hesitation she lifted the tape again.
"Then post-erection size…."
Her delicate hand closed around my cock once more. Feeling how much larger and harder it had become, her shoulders jerked.
"Heh…."
Stunned by the size, she parted her lips and blinked. The expression said she could not believe the massive thing in front of her. I clearly saw her swallow hard while staring at my cock.
"Now… just the semen test left. Need to check sperm count and motility…."
She started to step back again.
"Masturbate by yourself and put the semen in the container. I'll step outside for a bit…."
"Teacher."
I called her again.
"Help me with this too."
The school nurse's eyes grew even rounder than before. She stared at me blankly. Unconcealable joy and anticipation shone in that face.
"S-someone like me… is it really okay?"
"You're the teacher."
A look of pure emotion crossed her features.
"Thank you. I'll show you the best paizuri service."
The school nurse dropped to her knees in front of me where I stood. Without hesitation she began undoing the buttons of her blouse. When the white blouse fell open, full breasts cupped in a black lace bra came into view.

With an unmistakably eager expression she removed the bra as well. The two lush mounds swayed lightly under gravity. Before I could prepare anything she liberally squeezed love gel onto her chest. The slick liquid ran down her breasts and dripped.
"All right, then…."
The school nurse gathered her breasts with both hands and nestled my cock between them.
"Oh…!"
The sensation surpassed imagination. Warmer and softer than I had expected, the flesh pressed my cock from every direction. I learned for the first time that a feeling like this existed in the world. She worked her breasts as skillfully as if she had practiced for years, caressing my cock.
Theory had been perfect—no empty boast.
—Squelch, squelch.
Lotion and my pre-cum mixed into lewd wet sounds. I gently stroked her hair while savoring the rapturous sight before my eyes: my glistening cock between the white valley of her cleavage, her slightly parted red lips as she concentrated.
"Oh… Teacher, you've got good technique…."
"I practiced a lot alone at the academy with a cucumber."
She answered shyly and squeezed her breasts tighter. Every time her nipples brushed my lower abdomen my cock grew even harder. Lotion, her sweat, and my pre-cum blended into slicker, hotter friction. I kept stroking her hair.
"Haa… haa…."
The school nurse's breathing grew rougher. She was the one giving service, yet she looked as if she were the one being taken. Watching that aroused me further.
"I'm going to cum."
At my words her movements grew fiercer. She pressed her breasts with all her strength as if determined to milk every last drop. Not stopping there, she lowered her head.
—Lick.
A hot, soft tongue dragged across my glans. Completely different from the slickness of gel—the living texture of a tongue. For an instant I nearly jerked my hips back in surprise. Taking that as a signal, the school nurse opened her mouth wide and swallowed the head.
—Slurp.
My first paizuri service left me unable to think straight. Her tongue relentlessly teased the sensitive underside of the glans while her breasts clamped down hard all the way to the root in perfect rhythm. Unable to hold back, I gently gripped her head. Under my hand she looked up at me with obedient eyes. That lewd gaze sent the urge to cum surging up. I did not hold it back—I just came.
—Spurt, spurt, spurt!
A tremendous volume of semen erupted. The hot load poured entirely into her mouth. Eyes closed, rapturous expression on her face, she received my orgasm. When the climax ended she carefully pulled my cock free of her mouth and breasts. She spat the semen into the container that was supposed to collect it, then without hesitation licked my cock clean.
In the midst of that pleasure I thought: Should I just fuck her right here?
