I lifted Iseol noona, whose body had gone limp as though utterly exhausted.
Her soft body, which had been panting heavily in my arms moments ago, had no strength left in it.
I gently laid her down on the bed in that state.
“Ah, huh?”
“Noona, you can do it one more time, right?”
“W-wait, I just came….”
Noona called out to me in a voice mingled with bewilderment and the lingering afterglow of pleasure.
But instead of answering, I firmly grasped her sweat-slick waist with both hands.
This time, it was the missionary position—the position in which I'd lost my virginity.
Since I hadn't had much sex yet, this position felt the most familiar to me.
I settled myself between noona's legs. At last, my still-erect cock and her pussy met once more.
Her pussy, which had just taken my semen, still held onto its intense heat.
The flesh of her pussy was already twitching lewdly, as though craving my cock.
The hole in its center glistened enticingly, slick with her juices and my semen.
I deliberately didn't put it in right away. Instead, I gently rubbed the wet entrance with the tip of my glans.
“Ah…!”
Noona's body flinched and trembled.
As though tickled, she instinctively twisted her waist to avoid my cock, but I had a firm grip on her hips.
“Where do you think you're going?”
I whispered near her ear, brought my glans to her clitoris, and gently rubbed it.
When the small, sensitive nub met my hard glans, an uncontrollable moan burst from noona's lips.
“Ah, ah…! There, that feels strange…!”
There was a unique pleasure in watching a woman's reactions one by one, finding her sensitive spots, and teasing them as my own.
I had discovered a new kind of fun without anyone even teaching me.
-Squelch
“Hngh….”
When my glans touched the entrance, noona held her breath. Excited, I swallowed hard too.
Only after teasing noona enough did I begin slowly pushing my cock inside.
Holding her waist, I thrust my hips forward slowly—very slowly.
Though she was soaking wet, the sensation was still tight.
Thanks to her slippery juices, it was exactly the right pressure, and I inhaled involuntarily.
Still, perhaps because we'd just had sex in the cowgirl position, it felt as though her pussy was gradually adapting to the size of my cock.
“Ngh…!”
When my glans had fully entered, a moan burst from Iseol noona's lips. Her pussy was sensitive, and with my cock already so large, she seemed to feel it all the more intensely.
Every time my cock pushed farther inside, noona's pussy writhed like a living creature welcoming me.
Every fold of her vaginal walls swept over my cock, as though trying to memorize its shape.
“Huff… It's going in… Your whole thing is going in….”
Noona panted in an almost tearful voice.

The sensation of her body being filled with mine completely consumed her.
When I tried to pull my hips back, the elastic flesh of her pussy came slightly along with my cock.
The narrow, hot vaginal walls held onto my glans as though they were clenching it tightly and refusing to let go.
“Are you okay? It doesn't hurt, does it?”
I gently brushed her sweaty hair back and asked kindly, and she answered shyly.
“…Ngh.”
Noona nodded, and her pussy offered no resistance.
Instead, the flesh inside writhed as though wanting to take in more and clenched around my glans.
The slight movement made me want to move my hips wildly. I barely held myself back and savored the pussy whose virginity I'd taken only moments ago.
“I'm sorry. I wanted to do well in the cowgirl position all the way to the end… but I'm not used to a cock yet….”
Noona panted apologetically. It seemed her pride as an academy graduate and homeroom teacher had been wounded.
I chuckled and lightly kissed noona's cheek.
“It's okay. It was your first time in the cowgirl position. Stay still and I'll take care of everything.”
On Earth, as I remember it, women generally wanted men to take the lead, whether in romance or sex.
I didn't think women here would dislike men taking the lead, either.
At my words telling her to stay still, noona's expression relaxed slightly. I pushed the remaining length of my shaft inside.
-Slurp
“Hwaa…!”
At last, my cock settled inside noona again.
Because my cock was so large, I couldn't push it all the way to the base, but the inside of noona's pussy was filled with it.
A pleasant sensation swept through my entire body from the tip of my glans.
I began slowly moving my hips.
My thrusting was somewhat clumsy, but I tried to rock my hips as well as I had last time.
It was frustrating that I couldn't quite catch the rhythm, but even that alone brought incredible pleasure.
And noona, pinned beneath me, was feeling a far greater pleasure than I was.
“Hngh, ngh, ah…!”
I didn't know what being penetrated by a thick cock felt like to a woman, but noona's expression was already a disheveled mess, intoxicated by pleasure.
-Squelch, squelch!
Every time I moved my hips, noona's enormous breasts swayed voluptuously up and down.
The sight of her sweat-glistening white flesh rippling was itself the ultimate turn-on.
The visual stimulation made my cock swell even harder, and my hips began moving with more force without my realizing it.
Slap, slap—the wet, squelching sounds filled the room.
I gradually increased my speed. Noona's moans grew louder and lewder to match.
We hadn't even been having sex for a few minutes before I felt the urge to ejaculate surging up.
At this rate, I didn't think I could last even a minute. With every passing moment, I wanted more and more to come.
It was right then, as I wondered what I should do.
When I thrust inside, noona's hips, which had responded passively until then, lifted slightly and began moving with mine.
She began matching my sexual rhythm. Her pelvis moved gently up and down in time with my piston-like thrusts.
She also repeatedly tensed her muscles to squeeze her pussy tighter, then relaxed them.
It was probably a female technique for pleasing men, something she'd learned countless times at the academy.
Even without me holding her waist and leading her, noona was ready to accept me in any way she could.
‘This is insane.’
Once noona and I found our rhythm, the sex that had been nothing more than me chasing pleasure alone changed into an act we both enjoyed together.
It felt as though she knew what I wanted and I knew what she wanted—a sensation of us wantonly teasing each other's erogenous zones.
So this was where the skill of an academy graduate showed itself.
The sheer ecstasy of truly having sex together sent a powerful thrill tingling up my spine.
-Squelch, squelch, squelch!
Our bodies found the rhythm that suited each other, and the room filled with the sounds of flesh colliding and wet friction.
“Hngh, ah, ah! I didn't know it could feel like this—it's too deep…! Ahh!”
The amount of juices flowing from noona's pussy grew steadily.
By now, I barely felt any tightness at all.
Every time my cock scraped against her vaginal walls as it went in and out, sticky juices splattered in all directions.
“Hng, hngh, haaang!”
Noona arched her hips and let out a high-pitched scream. At the same time, her pussy convulsed and squeezed my cock tightly.
“Ngh!”
I sucked in a breath at the tremendous pressure of her pussy clamping down on my cock.
Overwhelmed by the sudden surge of pleasure, noona climaxed first even though I hadn't moved.
Trembling all over from the orgasm brought on by my cock, noona looked so lewd that I couldn't hold back any longer.
“I'm coming…!”
A sharp pleasure erupted from my thighs and shot up along my spine.
Holding noona's waist, I began pouring my hot semen into the deepest part of her pussy.
-Brrrshhh! Brrrshh!
I didn't stop moving my hips even while ejaculating. I couldn't stop.
Every time her convulsing vaginal walls rubbed against my hypersensitive glans, I felt my brain grow hot.
It was an insane pleasure. The sensation of rubbing my glans wildly while ejaculating was incomparable to anything I'd ever felt in my life.
My mind was filled with nothing but rubbing my cock.
“Wait, Sihyeok, if you move while you're coming…! Nooo…!”
Noona let out a moan that was almost a howl and sprayed her orgasmic juices.
But I ignored her plea. The pleasure intensified beyond imagination, like a drug.
I couldn't stop shaking my hips.
I ignored noona even as she panted, unable to speak, and gripped the bedsheet tightly.
I pounded into her wildly, as though determined to wring out every last drop.
Even after I finished, I kept my cock inside noona for quite a while, leaving my hot traces within her.
How much time passed? I straightened my back with a satisfied sigh.
Noona struggled to catch her breath as she stared up at the ceiling with dazed eyes.
I buried my face in her pale chest and began deliberately leaving a dark hickey, as if to show it off.
-Smack
It was my first time leaving a hickey, and I was slightly flustered because the mark wasn't appearing as easily as I'd expected.
So I sucked even harder.
-Smooch!
With a cute sound, her soft flesh was sucked into my mouth. At last, a satisfying red mark bloomed on her skin.
