After my intense sex with Nari ended, I caught my breath for a moment.
The room was filled with a dense, fishy scent of sweat, semen, virgin's blood, and Nari's love juices mingling in the blazing heat.
I still had my cock inside her.
I admired Nari's naked body gleaming with sweat and her thighs faintly twitching in the afterglow of pleasure.
As expected, sex was satisfying in so many ways.
Through this encounter, I clearly realized the difference between academy graduates and current students.
The tightness of their pussies—and the stamina with which they maintained it—was on an entirely different level.
Iseol noona's pussy was a powerful masterpiece, honed at the academy and seeming to squeeze me dry right up to the very end.
Nari's initial explosive tightness, by contrast, gradually loosened as time passed, perhaps because of her weak sexual stamina.
Of course, that softness had its own appeal.
If I'd built up experience with countless women and grown accustomed to Iseol noona's tightness, I might not have been satisfied with Nari's pussy.
But for me, who had only just opened my eyes to sex, every pussy was a new world with its own charm.
Noona had the taste of a firmly trained pussy; Nari had the taste of a pure, soft virgin pussy.
There was fun in choosing what to eat.
I'd only ejaculated twice, but Nari had climaxed more times than I could count.
After she'd surpassed ten, I gave up counting. Her body was already at its limit.
-Pop!
The sound of my cock slipping out rang through the room, and the semen filling her pussy gushed out.
Nari could no longer even moan; she merely panted heavily. She was utterly exhausted.
‘Still not enough.’
As I pulled on my underwear, I found myself wanting to have sex.
One blowjob and two rounds of sex. I'd only ejaculated three times today.
The heat burning inside me would take a long time to cool down.
Fortunately, I'd already prepared my next target.
When Nari briefly lost consciousness after squirting earlier, I'd called someone else in.
I lightly patted Nari's plump, limp buttocks.
Smack, smack.
The resilient feel pressed into my palm.
This is more fun than playing with my phone.
Just then, the door to the sexual-relief room opened.
“Huh? The class president and… Nari?”
The gyaru-style girl Yuna had opened the door and entered.
As soon as she entered the room, she spotted Nari sprawled on the bed as though unconscious, and her eyes went round for a moment.
But she soon curled her lips into a sultry smile, as though she'd grasped the situation.
“Nari's totally out.”
Yuna looked over my naked body and my cock, which was still twitching.
My cock was covered in semen and Nari's love juices, remnants of what had just happened.
“It's filthy. Want me to clean it with a blowjob?”
Sitting in the center of the bed, I shook my head. Then I beckoned her with a gesture.
“Come here.”
Yuna sauntered over and straddled my lap.
She climbed onto my legs and lightly rubbed her pussy against my cock.
She hadn't been penetrated yet, but the mere fact of Yuna's buttocks settling onto my thigh was immensely stimulating.
An off-the-shoulder top, a choker necklace, and a black sheer blouse.
Yuna's pretty outfit created a lewd atmosphere.

“Looks like I'm lucky after all. I knew I'd get a chance to be called over by a handsome man like you, Sihyeok.”
Yuna said with a pretty smile.
Her smile was filled with confidence.
Without even waiting for my answer, she leaned in and kissed me.
The kiss Yuna initiated felt incredibly good.
Her tongue was unbelievably soft and supple. It felt amazing.
But….
‘A little presumptuous, isn't she?’
There was a subtle arrogance in her actions, as though she were testing me.
No, to begin with, was it really okay for a woman to boldly kiss a man first like this?
As someone already steeped in this world's ideology of male superiority and female subordination, I was a little taken aback.
I had no idea what had given her the nerve to kiss me.
Yuna's tongue wasn't as skillful as Nari's, but it was bold and straightforward.
It entered my mouth without hesitation and explored every nook and cranny as though surveying its own territory.
She tickled my gums with the tip of her tongue and gently scraped the roof of my mouth.
She stirred my mouth wildly with her tongue, but it wasn't unpleasant because it was so soft.
Besides, her breath was fresh, as though she'd just freshened up, which I liked.
“Mmm… Class president, you're good at kissing, huh? You must have been with a lot of women?”
Yuna placed a hand on my shoulder and swallowed the saliva I'd passed to her with a gulp.
Even while kissing, she occasionally breathed warm air against me and whispered.
Instead of answering, I lightly bit her lower lip.
“Hng…!”
Yuna must have found it pleasurable rather than painful, because she made a nasal moan and wrapped her arms around my neck.
With a soft smack, our lips parted.
I gave her a slight smile, grasped Yuna's shoulders, and gently laid her down on the bed.
“From here on, I'll take the lead.”
Yuna looked slightly surprised, as though she hadn't expected a man to say something like that.
But soon an even deeper smile spread across her lips.
“Are you mad?”
Her voice was coquettish as she asked.
Instead of answering, I reached for the buttons of her sheer blouse.
“Who knows? First, I'll teach you some manners.”
I began undoing the buttons of her blouse one by one, very slowly.
As the buttons came undone, more of her ample cleavage, squeezed together above her black bra, came into view.
“Hehe, Class President, you still have stamina left after having sex with Nari? What if you collapse while doing it with me?”
Yuna continued provoking me without losing her composure.
Instead of answering, I spread her blouse wide open.
Her enormous breasts, barely contained by the black lace bra, were fully revealed.
I gently brushed back her yellow hair.
Despite being dyed, her hair was remarkably soft.
I stroked her hair once, then resumed undressing her.
I took off her bra and pants, too.
“Actually, I've had a dream for a long time. To act cocky and then get properly disciplined by a man.”
Even as I undressed her, she didn't lose her provocative gaze.
“Will you make my dream come true today? Teach me a proper lesson with your cock, Sihyeok.”
I let out a slight laugh at that. Would she still be able to say that after being impaled on my cock?
Finally, when I removed her panties, Yuna was naked.
“Kyaa~”
A cute exclamation burst from Yuna's lips.
I moved between her legs and looked down at her pussy, already glistening with love juices.
As expected, it was the pussy of a female with meticulously groomed pubic hair, wet from kissing.
Either way, she was the kind of female who got aroused and wet just from having a man nearby.
I brought my glans to the entrance of that pussy and thrust my hips forward hard.
-Squelch!
“Haaang!”
I plunged in hard and deep from the very start.
Unlike her flashy appearance, Yuna's pussy was soft and innocent.
Her very supple vaginal walls accepted my cock without resistance.
Thanks to the copious lubrication and her soft inner walls, I felt not the slightest friction even during my rough thrusting.
“How's your first cock?”
I hadn't even considered that she might not be a virgin.
In a world with so few men, the women who weren't virgins were probably only the truly exceptional ones.
And, of course, Yuna was a virgin.
“It's so… big… Hoo…!”
“So, have you learned some manners?”
“It's still not enough…!”
The instant I heard that, I climbed on top of her.
Then I raised both of Yuna's wrists above her head and restrained her arms.
-Thwack! Thwack! Thwack!
“Haa, aaah…!”
The sounds of flesh slapping together and Yuna's uninhibited moans mingled in a sticky chorus.
As Yuna wished, I moved my hips even more violently.
The piston-like thrusting back and forth had changed into a mating-press position, with her legs raised over my shoulders.
I drove into her in pounding up-and-down thrusts.
Each time my glans pounded against her cervix, her love juices splattered in every direction.
Yuna's voice rose higher and higher.
“Ah, ah! I like it…! More, more…!”
Yuna had lost her initial composure and moaned, focusing solely on pleasure.
Whereas other women, whether consciously or not, had tried to make their moans cute and pleasing to hear, Yuna didn't hold back at all.
Just by listening to her voice, I could tell which spots felt better and how I needed to thrust to make her feel it more.
Enjoying her reactions, I drove her even harder.
Before long, Yuna reached her first climax.
“Aah, hiii, kyaaang…!”
Yuna let out a sharp scream and clawed at the pillow.
Her exhaustion was obvious, but at the same time, her face was alight with extreme ecstasy.
“Haa, haa… More….”
She panted and whispered.
“Punish me more… Sihyeok….”
At her plea, I grinned.
It was cute that Yuna didn't give in even as I pounded my cock into her so hard, and it also stoked my competitive spirit.
Yuna met my eyes and shouted.
“Make my pussy a mess…!”
There was no way I could back down after hearing a female tempt me with such raw, genuine desire.
