Hayeon, Headed to the Bathroom?
A few days after I accepted Subin and Chaerin’s confessions, it was Thursday lunch the following week.
The bed in the Sex Treatment Room was already slick with the sweat and fluids of Seol noona and me.
I rocked my hips above her limp, panting body, a light sheen of sweat on my own skin.
—Squelch, squelch, squelch!
“Aahh, haah, haeuh, nn…!”
“Hoo, hoo.”
The wet slap of my hard flesh against her soft thighs and her lewd cries rang in my ears. The scent of sex hanging between a man and woman in the middle of mating was so thick it made my head spin with the filthy atmosphere.
“Haeuh, ah, ahh…! S-Sihyuk…! Wait, just a second…!”
I had no idea how many times she had already climaxed. Her moans were practically sobs. But contrary to her words, her pussy still greedily clung to my cock and refused to let go.
It was definitely different from our first time not long ago. Whether she had been training on her own or not, she was lasting far longer and gripping me much tighter.
—Squelch! Squelch! Slap!
“Huk, huk, huk…!”
Her pussy was a masterpiece. Every fold inside her cunt came alive, writhing to mold itself around the shape of my cock. Fully accustomed to my dick now, Seol noona’s pussy made filthy wet sounds every time I moved my hips and sucked me deeper.
That was exactly why I called her to the Sex Treatment Room so often.
I grabbed both her arms, pulled her toward me, and drove my cock even deeper.

“Hyaaah! My womb! You’re hitting the entrance to my womb! I can’t take this relentless pistoning…!”
I slammed into her and tried to kiss her, but her big tits filled my vision instead. So I pressed my mouth to those sweat-slicked mounds rather than her lips. No milk came out yet, so there was no taste, but every time I teased her with the tip of my tongue or lightly bit a nipple, the pure female reactions that burst out of her pleased me immensely.
After pounding her like a beast for a long while, the first wave of orgasm finally hit me.
“I’m cumming…!”
—Brrrthhh!
I gripped her arms tight and unloaded a thick load of semen deep inside her. My cock pulsed and kept pumping out cum as if it refused to spill a single drop outside. I closed my eyes for a moment in the pleasure of release, and when I opened them again I saw Seol noona’s back as she gasped for breath.
Before the afterglow of the first ejaculation even faded, I slowly started moving my hips again.
—Slap, slap, slap.
“W-wait… Sihyuk, just rest a little, ughh?!”
She begged, but I simply lifted her legs and hooked them over my shoulders.
“You’re a teacher, noona. How can your stamina be worse than the college girls?”
It was a joke. Seol noona’s sexual stamina was far superior to most women. She was only struggling this time because I had gone full throttle from the start.
I grinned and worked my hips hard again for the second load.
“Haaahng! Ah! Ahh! I came, I already came earlier, I’m cumming againnn…!”
She screamed and hit her tenth orgasm. But she didn’t go limp and useless like before. Instead she wrapped her legs around my waist and begged for even more pistoning. An Academy graduate—and a teacher at that—really was built differently.
“Open your mouth.”
I demanded a kiss while still pounding her mercilessly. She opened her lips as if she had been waiting for it, and I shoved my tongue roughly inside. Just like my cock, my tongue thoroughly explored her depths.
“Haeup, chuu, zzok, while we kiss, deeper inside my pussy, more, more…!”
Even mid-kiss she kept craving more pleasure. I was the same. While my tongue ravaged her mouth, I swirled my glans deep inside her cunt.
“Hiiik…! No! If we come together…! I’m cumminggg!”
In the end she white-out climaxed once more. The trembling of her pussy transmitted straight through my cock. Her panting was so sweet I could tell she was blissfully happy deep down.
Not long after, her sly little hand teasing my chest pushed me over the edge and I came again.
“Haa, haa… Sihyuk’s cock is always so intense….”
“So you hate it?”
“No… that’s why I like it even more….”
After we finished, Seol noona burrowed into my arms like a cat and used my arm as a pillow. It was the face of a thoroughly satisfied female.
We stayed like that for a long time, sharing body heat and chatting about nothing important.
“Did you watch the drama yesterday? At the end the male lead…”
“I don’t watch dramas.”
In this world every drama was written for women’s tastes, so most of them ended with the heroine marrying the guy.
“How was today’s blowjob practice? Did I suck too hard?”
“You sucked just right, like always. No need to worry about your blowjob skills, noona.”
Ordinary talk, sometimes dirty talk. While we chatted she nuzzled her face against my chest with a silly smile, as if my arm pillow felt that good.
“You like the arm pillow that much?”
“Yeah. It makes my heart so calm….”
That pure answer made me suddenly curious.
“Noona, do you ever think about getting married?”
“Huh…?”
She looked up at me with a startled expression. Clearly she never expected a man like me to ask something like that. She answered while desperately trying to suppress the hope in her eyes.
“I-I want to… but I never met a man I liked, so I couldn’t….”
I smiled quietly to myself. It wasn’t that she never met a man she liked—it was that no man would marry her. In this world a woman around twenty-five was already wine starting to go bad.
“I see.”
I lightly pinched her cheek as I spoke.
“How come nobody snatched up a cute noona like you?”
“R-right…?”
She was too embarrassed to say anything more. After a short silence she spoke up as if she had just remembered something.
“Ah, since everyone finished deep-throat practice, we’ll start the actual deep-throat sessions from tomorrow.”
I answered that I understood and kissed her. I figured it was about time I wandered around the Academy looking for more decent women, or called Chaerin or Subin to the Sex Treatment Room.
My wife candidates are…
Chaerin and Subin were already locked in. Seol noona wasn’t bad either. Long-tongued Nari, track-and-field Yeji, and gal Yuna were all fine. Come to think of it, almost every girl in my class was fuckable. Having this many beautiful girls who got me hard in one class felt almost unfairly lucky.
Once I got married I would fuck at least two of them every day on rotation. I planned to pick only the pretty ones.
Just imagining daily sex made my lower half grow heavy again.
I left the Sex Treatment Room behind, leaving the sweet time with Seol noona in the past.
As I walked down the corridor I spotted a familiar figure up ahead. Snow-white silver hair. Baek Hayeon.
She was walking quickly toward the end of the hallway, looking somehow anxious. The preparatory bell rang, signaling that lunchtime was almost over.
Without much thought I called out to her.
“Hey.”
At my voice Hayeon’s shoulders flinched and locked up. She slowly turned around with an expression as if she were looking at a disgusting bug.
“What do you want.”
“Lunch is almost over. Where are you rushing off to?”
“…….”
Instead of answering she only shot me a glance mixed with contempt and a little fear. That look clearly said, Why the hell do you care?
“None of your business.”
She snapped coldly and spun around again, hurrying toward the end of the corridor as if something were chasing her.
“Heh. Makes me want to fuck her.”
I let out a hollow laugh of disbelief and was about to ignore her and go my own way. Then I suddenly noticed that Hayeon’s movements looked unnatural. Beyond just walking fast, she kept twisting her hips ever so slightly as if something was uncomfortable.
What? Is she hurt somewhere?
At first I meant to ignore it. But curiosity raised its head inside me. Where was this pitiful girl who insisted she was a man—clearly suffering from some mental illness—heading right now? Had she injured herself? Did she need help?
I silenced my footsteps and began tailing her.
Hayeon walked a long way down the corridor. She wasn’t heading for the Health Office, the classroom, or the club building. She was going toward an old annex tucked away in a quiet corner of the Academy where almost no one went.
When she reached the annex she looked around repeatedly like the protagonist of a spy movie, checking several times that no one was watching. That nervous behavior only made my curiosity grow.
At last the place she entered was the men’s restroom. Without a second of hesitation she opened the door and slipped inside.
At first I was dumbfounded, but a fun idea soon followed. Sex in a men’s restroom—wasn’t that hot as hell?
I checked the surroundings myself, then silently followed her into the men’s restroom.
The interior was old and cool. Only a musty smell hung in the air. No one was in sight. Only the stall door at the very end was tightly shut.
—Shhhhhhhh.
The sound of pissing came from inside the stall. She seemed to be relieving herself quite freely. I leaned against the wall right in front of the door.
The pissing sound continued for a long time before finally stopping. Then a mechanical whirring noise started, followed by the sound of water spraying. She was using the bidet. She had walked into the men’s restroom with a female body and was casually taking care of her business.
A moment later there was a click, and the stall door opened.
Hayeon, finished with her business and stepping out, came face-to-face with me standing right there with my arms crossed, waiting for her.
“……!”
Her eyes flooded with pure shock.
“Hey.”
