After I finished showering and opened the door, Iseol noona, who had somehow recovered her strength, was sitting on the edge of the bed waiting for me.
She was wearing only a loose white dress shirt that looked as though she'd found it in the shower room. It was probably spare clothing kept in the sexual-relief room.
With several buttons undone, the cleavage of her voluptuous breasts—where I'd just left a hickey—was dangerously exposed.
At the sight, the lust I'd thought I'd washed away in the shower began rising again.
“Sihyeok….”
When I sat beside her, noona called to me softly.
“I'm sorry I couldn't attend to you while you showered.”
It was an unexpected apology. Her words made me chuckle.
How could someone who was nearly unconscious have attended to me in the shower? I naturally extended my arm.
“Wait a moment.”
At my words, noona's body stiffened once more. She seemed tense, thinking I was about to have sex again.
Enjoying her reaction, I laid noona down on the bed, then carefully slid my arm beneath her neck.
It was the classic arm-pillow position.
“Isn't it easier to talk like this?”
It wasn't a particularly meaningful action. Since there was a bed, I simply thought it would be more comfortable to lie down and talk.
Besides, we'd already had sex twice, and I wanted to lie together like lovers.
Noona's body went stiff at my action.
Her eyes darted uncertainly, apparently flustered by the sudden closeness.
When our eyes met, noona jolted in surprise and turned her head away. Her reddened earlobes revealed everything she was feeling.
Having a man use his arm as her pillow must feel pretty good.
“Cute.”
I gently held noona's face and turned it toward me.
Drawn by my touch, her face slowly moved closer to mine.
Her moist eyes, slightly parted lips, and defenseless expression—I couldn't hold back any longer and kissed her.
-Smack
At first, our lips merely met lightly. Hot breath escaped between noona's lips, which had parted slightly in surprise.
Aroused by their softness, I didn't hold back, letting my tongue briefly meet hers.
“Mmph…!”
Noona's shoulders trembled. But she apparently didn't dislike it, because she soon closed her eyes and accepted my kiss.
How much time passed? When I pulled my lips away, noona's face was completely relaxed.
It was cute that, despite having just passionately joined our bodies, she was shy over a simple kiss. I gently embraced her.
“Is it uncomfortable? Should I take my arm out?”
“…No. Keep doing it.”
Noona burrowed deeper into my embrace and whispered. She must have really liked having my arm as a pillow.
I hugged noona even more tightly. She exhaled happily and buried her face in my chest.
We lay there talking about this and that for nearly an hour.
“How could you not have gotten married when you're this beautiful?”
At my question, noona gave a small laugh in my arms.
“That's the first time anyone's ever called me beautiful.”
“You're lying. With a face like that, you've never heard it before?”
“No. Women were only interested in being chosen by men. To men, I was probably just one of the women who were passably attractive.”
Faint resignation colored noona's voice.
I was gradually beginning to understand how deeply wounding it was for the women of this world not to be chosen by a man.
“Those men were idiots. They failed to recognize a treasure like you.”
I said it while gently stroking noona's hair. Under my touch, her body grew even softer, like a cat.
“Sihyeok.”
“Yes, noona.”
“You… really have a strong sex drive. I was taught that ordinary men aren't like this.”
“Is that so? I thought this was normal.”
I lied as casually as I could. She rubbed her cheek against my chest and whispered.
“I heard other men get tired immediately after sex. They probably can't even imagine hugging someone like this or talking….”
“I like it. Your body is incredibly warm and soft, noona. I want to keep holding you.”
At my words, noona's body gave a small start. Then, after a moment, she murmured in a voice barely loud enough to hear.
“…I like it too.”
For some reason, ever since I gave her an arm pillow, noona seemed to be acting spoiled with me.
So we chatted about trivial things.
She told me how she'd become a teacher immediately after graduating from the academy, how she still hadn't found a man to marry, and even that she disliked drinking and smoking.
I listened quietly to everything noona had to say.
Then, as though we'd made a silent pact, we slowly fell asleep in the warmth of each other's bodies.
* * *
How long had we been asleep? A bell rang throughout the academy.
It was the sound announcing the end of the major class. I slowly opened my eyes.
The first thing that came into view was Iseol noona's face, sleeping peacefully in my arms.
Her long eyelashes cast delicate shadows over her cheeks, while her pert nose released soft, steady breaths.
The neat, mature teacher I knew was nowhere to be seen; in her place was a cute face sleeping defenselessly, with all her defenses lowered.
The peaceful sight brought a smile to my face before I knew it.
But it was getting time to leave. I carefully woke noona, slipped my arm free, and rose from the bed.
“Noona, class is over. We need to go hold the closing homeroom.”
“Mmm….”
At my call, noona shifted drowsily before opening her eyes.
“Noona, you need to get dressed.”
I tossed noona the neat skirt suit as she sluggishly stirred on the bed, then left the room.
“I'll go on ahead, Teacher.”
It would have been strange to enter the classroom together with my homeroom teacher, so I went ahead.
“…Yes. Take care, Sihyeok.”
Noona seemed disappointed that I was speaking formally. She must have wanted to keep talking to me casually.
The hallway, where the major class had just ended, was quiet and filled only with sunlight.
I walked slowly, savoring the afterglow of the incredible sex we'd just had.
That was when it happened. A familiar figure appeared as it rounded the corner of the hallway ahead.
It was Seo Yeji.
She was glistening all over with sweat, as though she'd just finished exercising.
Yeji, looking as lively as ever, spotted me too.
“Oh, class president?”
Yeji stopped for a moment when she noticed me, seemingly surprised.
Yeji's outfit… frankly, being naked would have been more modest.

First, there was her white sports bra, soaked with sweat.
The contours of her enormous breasts, easily a G-cup, were clearly visible through the fabric.
Her nipples, clinging to the wet cloth, flaunted their arousing presence even though they weren't erect.
Lowering my gaze, I saw blue bloomers so tight that they nearly revealed her cameltoe.
Every time she took a step, her firm, athletic buttocks swayed enticingly from side to side.
Her neck and thighs glistening with sweat, her breasts rising and falling with her labored breaths, and her wet ponytail fluttering in the breeze.
Yeji's body was the very embodiment of health and sex appeal.
“Finished exercising?”
“Yeah, I finished a little while ago.”
Yeji answered with a broad grin. There was a refreshing openness to it that was hard to find in other women.
The healthy, salty scent of sweat characteristic of a woman fresh from exercise wafted from Yeji's body.
Strangely, though, the smell coming from Yeji's body felt attractive to me.
It was a scent that stimulated my instincts, incomparable to artificial perfumes and the like.
‘Am I a pervert?’
I marveled inwardly at my body, which grew aroused at the smell of sweat, and at Yeji, whose sweaty scent didn't even bother me.
If the other women were submissive livestock, Yeji felt like an untamed wild horse.
What would sex with a woman like her feel like? As I thought about it, my cock swelled thick and heavy again.
Afraid Yeji would notice my erection, I hurriedly changed the subject.
“By the way, what brings you to the infirmary? Did you hurt yourself?”
“Oh, I fell while practicing track and field a little while ago. My bandage came off, so I'm here to get a new one.”
Yeji pointed at her own knee as though it were nothing.
I offered a word or two of concern, then parted with Yeji and returned to the classroom.
The classroom was already bustling with the female students who had finished their afternoon major class.
Their gazes all poured onto me, but by now I was fairly used to it.
While Chaerin and Subin chatted beside me, Yeji—and even Iseol noona—returned before I knew it.
“Tomorrow, we'll learn the pillar-fellatio technique, followed by theory and practical training in the advanced deep-throat course.”
“And on Friday, there will be an orientation on club activities instead of a major class, so please keep that in mind. That's all for today's class.”
After finishing the announcements, noona's gaze naturally turned toward me.
Meeting her eyes, I silently mouthed the words so only she could see.
“Today's sex was the best.”
Whether she'd understood my compliment or was simply amused by a man mouthing words, her earlobes turned faintly red.
She smiled faintly and nodded. Her eyes seemed to say, ‘I'll do an even better job the next time we have sex.’
