School Nurse, Were You Masturbating?
The lunch period ended, and the bell rang to signal the start of afternoon classes.
The female university students who had been with me rose from their seats with looks of regret.
"Ah, it's already over."
"I wanted to talk more with the class president."
"I know. It would have been nice if we could take the afternoon classes together too."
They each voiced their disappointment and scattered toward their major lecture halls. Chaerin and Subin, who were always at my side, left for their own major classes as well. Just like that, I was left alone in the empty classroom.
At the academy, men were required either to ride the male-student shuttle once classes ended or to head home accompanied by at least one woman. The rule had been put in place because, despite the nation's thorough brainwashing education, far too many women still couldn't restrain their lust and would assault men.
The women's classes, however, still had a long way to go. Riding the shuttle home alone would only leave me bored out of my mind. In the end I decided to wait until Chaerin and Subin finished, and to kill time I began wandering the academy campus.
The academy was far larger and more systematically laid out than I had imagined. Leaving the classroom, I found carefully tended lawns, dense tree-lined avenues, and elegant European-style stone buildings stretching endlessly. Between the buildings, pretty gardens and benches had been placed here and there for students to rest. On the broad athletic field, the women's soccer team was sweating through a match.
Yet the scene was nothing like the soccer I knew. Their so-called uniforms were little more than bikini tops and hot pants so short that the cleft of their asses was fully visible. I had never cared much for soccer, but every single outfit was shamelessly vulgar, and the players were all pretty with outstanding figures, so I found myself unable to look away.
On the track beside them a familiar figure caught my eye. Looking closer, it was Yeji. Her attire was equally far from ordinary—a thin white sports bra soaked transparent with sweat, and blue bloomers pulled so tight that her camel toe stood out like an axe mark. Every step she took made her springy ass sway enticingly from side to side. Sweat gleamed along her back and thighs; her breasts rose and fell with each labored breath. Her ponytail fluttered in the wind, and the concentrated profile of her face was both healthy and sexy.
I involuntarily parted my lips in admiration. Yeji was only running, yet the near-bikini athlete's outfit and her voluptuous body had me rock-hard. Honestly, if she had asked me to fuck her right then, I would have done it without a second thought. I was reminded once again how weak I was to lust. Afraid the erection would never go down if I kept staring, I hurriedly averted my eyes and walked on.
Beside the track stood a massive indoor gymnasium and a swimming pool under a glass dome. The sight of the women's swim team through the glass was something else entirely. I doubted whether what they wore could even be called swimsuits. The ones in bikini-level suits were the modest ones. Some wore nothing but nipple patches that barely covered their areolas and a single hand-span of fabric that clearly outlined every strand of pubic hair—another shock. One nameless student in particular had such large breasts that they bounced heavily every time she broke the surface. The design cared nothing for reducing water resistance; its sole purpose was to draw a man's gaze.
Marveling at the women's lewd clothing and the sprawling campus, I kept walking. Only after a long circuit did I finish a full lap. The place truly deserved the name "university." My feet eventually stopped in front of a familiar building—the one that housed the infirmary and the Male Sexual Processing Room.
The memory of taking my homeroom teacher, big sister Iseol's virginity in that very processing room yesterday made my cock twitch hungrily. I stepped into the infirmary. I had no real business there; I was simply bored and thought I might scrounge a snack from the pretty school nurse if luck was with me.
Inside, the place was dead silent. A few papers lay on the desk and no one was in sight. More precisely, one of the soundproof booths at the back—rooms provided for female students to masturbate and stave off estrus sickness—had its door firmly shut. There was no lock, only opaque glass that let you see a silhouette of whoever was inside.
Focusing on the glass, I made out a blurry figure writhing on the bed.
Who is it?
Curiosity pulled me closer to the soundproof booth.
"Hnn… haa…."
Faint female moans and the wet sound of something slick rubbing together leaked out. The realization that a woman was masturbating right on the other side of the door set my heart pounding. The urge to open the door and walk in flashed through my head. Of course I shouldn't…
No. Thinking about it, why can't I just go in?
In my previous life it would have been unthinkable. Barging into a room where a woman was masturbating would have branded me a sex criminal and ruined me forever. But this world was different. Men were beings to be protected. Women existed to satisfy men's desires. The passionate lecture big sister Iseol had given that morning echoed vividly in my mind: men were the hope of humanity's survival, so even their trivial desires deserved respect; for a woman to show her body to a man was not shame but glory. Therefore, unless a man committed a truly serious crime, he was simply let off. Walking into a room where a woman was masturbating? That wasn't a crime at all. If anything, the woman caught in the act should be grateful.
The laws and common sense of this world mocked the moral shackles inside me and pried them open. For a moment the unease that had risen with the memo I found yesterday tried to surface again. I had sworn to hold back from lewd things and be careful with my body. That cool-headed resolve proved utterly powerless against the lust boiling up and the curiosity about the masturbation happening beyond the thin door. The front of my pants was already swollen to the point of pain.
I'll just take a quick look, apologize, and leave. That should be fine.
Making excuses to myself, I carefully opened the door.
What met my eyes was a sight beyond anything I had imagined.
On the bed inside the room, the school nurse lay with her white coat thrown open, legs spread wide, masturbating with fierce intensity.
"Hnn, hnn…! Ah, unngh…!"

Eyes closed, she frantically rubbed her pussy with fingers glistening from her own juices. Through the open coat her full breasts spilled free, pink nipples already hard and erect. Completely lost in her own pleasure, she had no idea I was there. Every time her fingers brushed her clit her back arched, and lewd cries spilled out with her hot breaths. Sweat-matted hair showed just how long she had been at it.
After a while she cracked her eyes open, spotted me, and startled violently.
"W-Who's there! Didn't you see someone's inside…!"
The voice was furious at first, but the instant she recognized the person in the doorway her tone shrank to almost nothing. Anger vanished, leaving only extreme fluster and shame on her face.
"S-Sihyuk? What brings you here…?"
I reflexively delivered the excuse I had prepared.
"Ah, I'm sorry. I didn't realize anyone was inside and walked in."
My eyes, however, paid no attention to her words. They were locked on the way she hastily tried to close her coat and pull on her panties—pubic hair soaked and sticky with love juices, black stockings that rose precariously high on her thighs, and soft white skin still trembling faintly from the aftershocks of pleasure. The first time I had ever watched a woman masturbate was far lewder and more stimulating than anything I had imagined. My erect cock strained hard against the front of my pants.
From the name tag I had just glimpsed I learned the school nurse's name was Lee Seoyeon. An ordinarily pretty face and a voluptuous body—I was already too excited to hold back.
"I'm really sorry you had to see me looking so unsightly…."
Seoyeon finished pulling on her panties and stood from the bed, desperate to escape the situation. But when she found me still blocking the doorway and refusing to move aside, she faltered. Her gaze drifted, almost against her will, to my cock. The massive outline stood out unmistakably fully hard.
—Gulp.
I heard her swallow dryly. She hesitated a moment longer, then gathered her courage and asked,
"Do you need sexual processing?"
