Mating Press on Noona
Barely recovering her senses, my noona wrapped her legs around my waist as if she were trying to be cute.
“Haa… haa…”
Even while panting hard, she stretched a hand up to my chest and lightly teased my nipple with her fingers.
I’d never really been touched there before. The unfamiliar sensation was ticklish yet strangely pleasant, making my body twitch.
“I’ll practice harder next time so I don’t disappoint you.”
Her voice still hadn’t fully returned to reason. The way she sounded both exhausted and happy from climax was adorable.
I gave a small smile, watching her assume the sex was already over.
“Noona, we’re not done yet.”
At my firm words, her body went stiff.
“Huh? Wait, Sihyuk…! I just came twice…!”
She cried out in a flustered voice. Even for someone like me, she must have thought two climaxes in a row meant we were finished.
But my cock mocked that expectation, remaining rock-hard without the slightest hint of softening.
“Twice isn’t enough for me.”
I unwrapped the legs coiled around my waist and spread them even wider.
There was no resistance. Of course there wasn’t—a woman wasn’t supposed to resist during sex.
At the sudden change in position, noona could only stare up at me with wide, round eyes, completely at a loss.
“Huh? Wha…?”
Her hips lifted slightly, tilting her pussy upward. Completely exposed, defenseless, open.
Just like before, her juices gleamed under the light.
Settling myself over her ass put me in the perfect position to slam my cock straight down—the mating posture.
“W-wait, this position feels a little weird…?”
“Yeah, it is a bit unusual.”
What was this position called again? Mating press?
I answered her innocent question lightly and put strength into my hips.
—Thud!
“Hyaaah!”
The sensation of burying myself deeper and harder than anything before was incomparable.

The wet, heavy sound of my cock punching into her pussy rang out loudly.
That visual and auditory assault hit her all at once. Her face flushed crimson in an instant.
At the same time, the relentless pounding against her cervix left her unable to think straight.
“Ah! Hnngh! Haaang! W-wait, I’m still…!”
Watching her thrash through another orgasm, completely overwhelmed, filled me with pleasure.
The pretty homeroom teacher in the sharp suit I’d run into earlier in the hallway had vanished without a trace.
What lay pinned beneath me now was nothing more than a female, helplessly conquered by cock, writhing in pure pleasure.
For the first time I realized I had a tendency to torment women with my cock and delight in their reactions.
Sex where we moved in sync was good. Sex where I simply took what I wanted was just as good.
“Noona.”
“Hauu… y-yes…? What…?”
“This time I’m doing it my way. You just feel it.”
I declared it like a statement of fact and began moving my hips in earnest.
—Slap, slap, slap, slap!
The rhythmic sound of my solid thighs smacking against her ass filled the room.
Even as pleasure scrambled her mind, she still struggled to answer me somehow. That expression was unbearably cute.
“Hnnngh, ah, ah! Ahh, it’s so deep…! Aaaang!”
Her moans drowned out the creaking of the bed.
I stopped thinking about using my weight to press down and focused on piercing her instead. Her reactions grew even more intense.
Apparently this world had no concept of the mating press. Noona shook her head wildly from side to side.
“I don’t know, I don’t know this…! Hyaa, hiiit…!”
Her pussy clenched tight around me, but after coming so recently I was still a long way from finishing.
“Noona.”
“Haaang…?”
“You’re really beautiful.”
“A-ah… th-thank… you…”
Being fucked by a younger man while moaning must have embarrassed her; she tried to turn her face away. So I deliberately caught her cheeks, forced her eyes to meet mine, and spoke sweetly.
“You’re cute.”
“Hnnn…”
—Slap!
I snapped my hips again, slower this time. Every time the head of my cock knocked against her cervix she gasped, spilling hot breath.
“From now on, when it’s just the two of us, I’ll call you noona instead of Teacher.”
I’d already been calling her noona casually when we were alone, but I wanted to make it official.
“Y-yes, yes…! Ah, wait…!”
Her lips pressed tight. Her thighs began to tremble.
Another climax was building.
“You have to answer me, Iseol noona.”
“Yeees… I-I like it…! I like it! I like it so much!”
Her pussy clamped down on me hard once more.
“Haaaaaang! I’m, I’m coming…!”
—Spurt!
“Hyaaaaang!”
She screamed as a fresh orgasm crashed over her.
I hadn’t even been thrusting that long. She came far too easily.
Was she especially weak to this downward angle?
Her pussy convulsed violently, squeezing my cock in tight pulses.
Fucking her while she was still climaxing and clenched felt completely different.
I licked her breasts, her collarbone, her throat while I kept pounding her, her head thrown back from the intensity of it all.
—Thud, thud, thud!
She was so far gone she could only make choked little “ugh, ugh” sounds, drool trailing from the corner of her mouth.
Even though she’d just squirted, her pussy still gripped me so tightly that every thrust dragged her folds with me, and the constant knocking of my cockhead against her cervix was obscenely erotic.
A few more minutes of that and she came again. These women really were premature, weren’t they?
“Hiit, hiik, hick…!”
Maybe her stamina had run out; this time she couldn’t even form words, just hiccuping gasps while her arms shook uncontrollably.
The moment she hit the peak of yet another orgasm, my own climax surged up hard and fast.
“Coming!”
I slammed my cock all the way down, pressing the head flush against her cervix, and poured out a thick load of fresh, hot cum.
—Brrrrt…! Brrrrrrt…!
“Hooo…”
The pleasure of ejaculation was, as always, perfect.
Even after I finished, I stayed on top of her for a long time, neither climbing off nor pulling out.
And just like that, our fierce bout of sex came to an end.
The air inside the sexual processing room was hot and thick. The scent of my sweat mixed with Iseol noona’s, of the cum I’d pumped into her again and again, and of her own juices, clung sticky and heavy.
The bedsheets were already soaked through and stained with fluids no one could tell apart anymore.
“Huu… huu… huu…”
Iseol noona was half out of her mind.
Her body, completely melted by pleasure, lay naked and limp across the bed without a single thread covering her.
Sweat-damp black hair stuck messily to the flushed nape of her neck. Her red lips parted slightly, thin breaths slipping between them.
The body I had made climax so many times still twitched faintly, unable to escape the aftershocks.
Even when I called her name she answered only with faint moans, and when I shifted my hips a little the pussy that had clenched so fiercely earlier had already lost some of its strength.
That lack of reaction cooled my excitement a little. Without her responses it just wasn’t as hot.
But while my mind was cooling off, my body was telling an entirely different story.
Even after coming several times, my cock was still swollen hard.
It stood upright, menacing, as if demanding the next woman.
This thing really is a monster.
I clicked my tongue and climbed off the bed.
Dragging my sticky body, I headed into the shower attached to the sexual processing room.
—Shhhhhh.
Warm water cascaded down over me.
Iseol noona’s scent and every trace of our intense sex rinsed away with the foam.
And strangely enough, the heavy thoughts that had been weighing on my mind seemed to wash away with the water as well.
The note that had been pressing down on me for a while now surfaced in my thoughts, but this time it brought no real anxiety.
Instead, the vivid memory of the fierce pleasure that had ruled my body only moments ago stood out in sharp contrast to that unease.
“Feels good…”
I muttered without thinking.
It felt good. Just this feeling of washing up after sex felt good.
Letting instinct lead me into sex felt far better and more profitable than filling my head with complicated thoughts.
I let out a short laugh.
I’d been overthinking everything.
Test subjects, surveillance, personality swaps—those were all nothing more than uncertain hypotheses. Sex, on the other hand, was real, immediate pleasure right in front of me.
If one round of sex could empty my head and make me this happy so easily, why had I been clinging so seriously to those headaches?
Yeah. Maybe possession was the right answer after all. Honestly, it felt like possession was correct.
It was the most comfortable conclusion, the one that let me accept the current situation most enjoyably. This way was far happier. I decided to think of it that way.
Hypotheses and all that headache stuff can wait. For now…
For now, I’d just enjoy myself.
Ignore the annoying things and just fuck the women who came my way, right?
After finishing my shower and drying my hair, I established a new principle of action.
Have fun. Fuck women however I want. If I picked up information along the way, fine. If not, also fine.
“Hoo…”
I let out a long breath and shook off the last of the tension inside me.
Sex was magnificent.
It was the best exercise for wiping away complicated worries.
Thinking it over again, possession still seemed more likely than some deliberate personality swap.
How could anyone fabricate memories this vast and detailed?
And it was hard to believe they would go to that trouble for someone as ordinary as me. What would they even gain by brainwashing a nobody?
