Noona finally regained consciousness and wrapped her legs around my waist, acting coyly.
“Haa, haa….”
Even while panting heavily, she reached toward my chest and gently tickled my nipple with one finger.
The unfamiliar sensation of having my nipple touched was ticklish yet pleasurable, making my body twitch.
“I’ll practice harder and won’t disappoint you next time.”
Noona’s voice still lacked its full composure. The way it sounded strained yet happy from the climax was cute.
I smiled faintly as I watched Noona, who seemed to think our sex was over.
“Noona, we’re not finished yet.”
My firm declaration made Noona’s body go rigid.
“Huh? Wait, Sihyeok…! I just came twice…!”
Noona cried out in confusion. She seemed to think that even I would stop after ejaculating twice in a row.
But as though mocking her expectations, my cock remained fully hard, showing no sign of subsiding.
“Two times isn’t enough for me.”
I untangled Noona’s legs from my waist and spread them even farther apart.
There was no resistance. No, a woman wasn’t supposed to resist during sex.
Faced with the sudden change in position, Noona didn’t know what to do and could only stare at me with wide, round eyes.
“Huh? Wha…?”
Noona’s buttocks lifted slightly, making her pussy point upward. Her pussy was spread open defenselessly, with everything exposed.
As before, her juices glistened beneath the lights.
With my position over Noona’s buttocks, it was the perfect breeding-press position for driving my cock straight down.
“This position is a little unusual…?”
“It is a little unusual.”
What was this position called again? The breeding press?
I answered Noona’s innocent question lightly and tightened my waist.
-Bam!
“Hyaaah!”
The sensation of my cock plunging in—stronger and deeper than before—was incomparable.

A loud thud rang out as my cock slammed into Noona’s pussy.
That visual and auditory stimulation assaulted Noona all at once, making her face flush in an instant.
At the same time, the cock pounding against her cervix left her unable to think straight.
“Ah! Hng! Haaang! W-wait, not yet…!”
It was fun watching Noona experience an orgasm, helpless to do anything but feel it.
The pretty homeroom teacher in the well-fitting suit I had met in the hallway had vanished somewhere.
All that lay pinned beneath me now was a female helplessly conquered by my cock and writhing in pleasure.
For the first time, I realized that I had a tendency to torment women with my cock and enjoy watching their reactions.
I liked both sex where we moved in sync and sex where I did as I pleased.
“Noona.”
“Haa, yeah…! Why…?”
“This time, I’ll handle everything myself. You just focus on feeling it.”
Declaring it like that, I began moving my hips in earnest.
-Slap, slap, slap, slap!
The sound of my firm thighs striking Noona’s buttocks rang out rhythmically.
Noona’s expression was cute as she struggled to answer somehow despite being unable to think clearly from the pleasure.
“Hngh, ah, ah! I-I knooow, s-stop…! Aah!”
Noona’s moans were louder than the creaking of the bed.
Rather than feeling as though I was simply slamming down with my body weight, I moved as though I were piercing her, making her reactions even more intense.
Apparently, this world had nothing like a breeding press, since Noona shook her head from side to side.
“I don’t know, I don’t know what this is…! Hyaa, hieet…!”
Her pussy clenched tightly, but since I had just come, I was still nowhere near ejaculating again.
“Noona.”
“Haaang…?”
“You’re really beautiful.”
“Ah, ah… Th-thank you….”
Perhaps embarrassed that she had moaned while being penetrated by a younger man, Noona tried to turn her head away for a moment. So I deliberately held her face, made her meet my eyes, and spoke sweetly.
“You’re cute.”
“Hngh….”
-Smooch!
I slowly thrust my hips again. As my glans pounded against her cervix, Noona panted and exhaled hot breaths.
“From now on, when it’s just the two of us, I’ll call you Noona instead of Teacher.”
Until now, I had casually called her Noona whenever we were alone, but this time I wanted to make it clear.
“Mm, mm…! Ah, wait…!”
Noona bit down hard on her lip, and her thighs began to tremble.
Another climax was coming.
“You need to answer me, Iseol Noona.”
“Yeees… I-I like it…! I like it! I like it!”
Noona’s pussy clamped down on me powerfully once more.
“Haaaaang! I-I’m c-coming…!”
-Pshht!
“Hwaaang!”
Noona reached a new climax with a scream.
She came so easily that I wondered if it was too soon, considering how little I had thrust.
Was Noona particularly susceptible to being pounded down from above at this angle?
Her pussy convulsed violently and squeezed my cock tightly.
The sensation of thrusting into a pussy that had just climaxed and was clenching hard was novel.
Overwhelmed by pleasure, Noona threw her head back, and I licked her breasts, collarbone, and neck as I thrust into her.
-Thud, thud, thud!
Noona had reached her limit and could only manage sounds like ngh, ngh as drool streamed from her mouth.
Even though she had just sprayed her juices, she clenched so tightly that the flesh of her pussy kept dragging along with my cock, while the sensation of my glans repeatedly knocking against her cervix was incredibly lewd.
After pounding her for a few more minutes, Noona came again. Women in this world really did seem to climax prematurely.
“Hieet, hieek, hik…!”
Perhaps she lacked the stamina, because during this climax she couldn’t even form words and merely made little gasping sounds while her arms trembled.
Just as Noona reached the peak of another climax, I suddenly felt the urge to ejaculate as well.
“I’m coming!”
With my cock driven down and my glans pressed firmly against her cervix, I poured out the freshly produced hot semen.
-Brrrshhh…! Brrrshhhh…!
“Hoo!”
As always, the pleasure of ejaculation was perfect.
Even after ejaculating, I didn’t climb down from on top of Noona or pull my cock out for quite some time.
* * *
And so our intense sex finally ended.
The air in the sexual-relief room was hot and heavy. The smell of our sweat, mixed with the traces of my semen ejaculated inside her several times and her juices, hung cloyingly in the air.
The bedsheets were already soaked and stained with bodily fluids whose owners could no longer be distinguished.
“Hwoo, hwoo, hwoo….”
Iseol Noona was nearly unconscious.
Her body, completely melted by pleasure, lay limp and naked on the bed without a stitch of clothing.
Her sweat-soaked black hair clung messily to her reddened nape. Her red lips were slightly parted, and thin breaths escaped between them.
Her body, brought to climax again and again, still trembled faintly as though unable to escape the afterglow.
Even when I called her name, she answered only with a faint moan, and when I nudged her waist slightly, the pussy that had clenched so fiercely before had lost some of its strength.
That sight cooled my excitement a little. Without a response, I was less aroused.
Yet while my mind’s excitement was fading, my body was telling an entirely different story.
Even though I had just ejaculated several times, my cock was still swollen and hard.
It stood stiffly, its head raised menacingly, as though demanding the next woman.
‘What a monster.’
I shook my head in amazement and rose from the bed.
Dragging my sticky body along, I entered the shower attached to the sexual-relief room.
-Shaaah.
Warm water streamed down over my body.
Iseol Noona’s scent and the traces left by our intense sex were washed away with the suds.
Strangely, even the thoughts weighing heavily on my mind seemed to be washed away by the stream of water.
The note that had been weighing on me for some time came to mind, but this time I felt no particular anxiety.
Instead, the vivid sensation of the intense pleasure that had ruled my body moments ago remained, contrasting sharply with that anxiety.
“Feels good….”
I muttered without realizing it.
It felt good. I simply liked the feeling of washing up after sex.
Having sex according to my instincts felt far more pleasurable and rewarding than filling my head with complicated thoughts.
I let out a short laugh.
I had been overthinking everything.
Being an experimental subject, being watched, having my personality replaced—all of it was merely an uncertain hypothesis. And sex was a real pleasure right in front of me.
If sex could clear my head and make me this happy, why had I clung so seriously to such troublesome problems?
Yeah, maybe possession really was the answer. Honestly, that seemed likely.
That conclusion left me most at ease and let me accept my current situation more happily. This was a much happier way to see things, so I decided to think that way.
‘Hypotheses and other headaches can wait. For now…’
For now, I’d enjoy myself.
I could just stop worrying about troublesome things and fuck the women who came my way, right?
After finishing my shower and drying my hair with a hair dryer, I established a new principle for myself.
Have sex with women happily, as I please. Whether I gained information along the way or not, it didn’t matter.
“Hoo….”
With a long sigh, I shook off the last of the tension in my body.
Sex was magnificent.
It was the best exercise for clearing away complicated worries.
The more I thought about it, the more likely possession seemed compared with intentional personality replacement.
How could anyone create memories this vast and intricate?
And it was hard to believe they had done this only to someone as unremarkable as me. What could they gain by brainwashing someone ordinary, anyway?
