Using My Trait on Yuna! (Training)
Back to the protagonist's perspective!
I resumed what I had been doing.
First, I yanked down her obstructing clothes in one swift motion.
Then I drove my rock-hard cock straight into her waiting pussy.
Twitch♡! Twitch♡!

Her pussy hole was visibly pulsing, as if it had been eagerly waiting for my cock the entire time.
Holding back after seeing that perverted bitch pussy twitching would be downright rude.
Schlurp!
Her already-broken-in pussy accepted me far more smoothly than before.
“Oghok♡!?”
I ignored her delighted moan and began thrusting with brutal force.
Squish! Squish! Squish!
“Oooogh♡! Ahk♡! Oghok♡!”
“Is something wrong? Why do you keep making those weird noises?”
How long should I keep pretending I didn’t know?
I felt like teasing her a little more.
“Ubuub♡! Ubuubuub♡!”
I did tell her to keep her head pressed down.
“Hey, you can stop pressing your head down now.”
Even though it must have made breathing difficult, she had been faithfully obeying the order I gave her earlier.
“Haaangh♡! Nooo♡ Oghok♡! Nothing’s wrong! Huaa♡! I’m fine♡! Oghok♡!”
She answered while panting roughly, clearly struggling to breathe after keeping her head down for so long.
“Then try to stay quiet.”
Making noise when nothing was happening was unacceptable.
“Yeees♡! Oghok! I’m! Sohhryyy....♡!”
She admitted her mistake and apologized, yet she continued moaning loudly.
This stupid bitch is still pretending she doesn’t know I’m balls-deep in her pussy.
How could anyone be that dense?
It looked like I would need to take special measures so she couldn’t possibly ignore it.
Its name: pussy heat massage!
“Hey! Heat massage starting now.”
I activated Body Temperature Regulation on my cock that was already buried inside her, rapidly heating it to an intense temperature.
Body Temperature Regulation — Extreme Heat Mode
“Uooohk♡???! It’s so hot♡! Please♡! Ungh♡! Ack!”
The sight of her suffering only made my cock burn even hotter inside her.
Her inner walls grew scorching.
Her heated pussy began flooding with love juices like a dam had burst, trying to protect its sensitive walls.
The burning pussy tightening from both pain and heat doubled the pressure around my cock, multiplying my pleasure.
Her pained cries were delightful, but she needed to be tormented properly.
“It’s for sterilization, so stay quiet!!”
Sterilization pussy, that was its name.
The heat massager sterilized her by thoroughly patting every inch of her insides, indiscriminately eradicating both harmful and beneficial bacteria.
While enjoying the pleasure of her sterilization pussy, I slapped her firm ass without mercy.
I could feel her pussy writhing in agony and clamping down in irregular spasms.
Each slap made her squeeze me even harder, as if her cunt was begging to be tormented more.
“Krrgh!! Sterilization pussy is the best!!”
“No it’s not!! Oghok! It’s not a pussy!”
Denying her own pussy? How ridiculous.
To think she would reject the sterilization pussy I was graciously bestowing upon her!
I raised my hand high and slammed it down on the impudent bitch’s ass with all my strength.
SMACK!!
“Kyaaaaahk♡!?”
Her eyes rolled back as she let out a beastly scream.
A bright red handprint burned on her ass while her pleasure-flushed pussy had veins bulging along its surface.
“Then what the hell is it, you stupid bitch!”
I slammed into her blood-engorged, crimson pussy even faster.
Thrust! Thrust! Thrust! Thrust! Thrust! Thrust!
“Ungh! Ok♡! Ok! Hole♡! Ungh♡! It’s just a hole!”
So now I should call it a sterilization hole instead of a sterilization pussy?
At this point she didn’t even deny it when I openly called her a stupid bitch.
“Just a hole”? She seemed to have developed her own unique concept.
Whatever denial or concept she came up with on her own, I ignored it and kept rapidly stirring her hole.
The more I stirred, the hotter my cock grew, and her overflowing love juices turned her pussy into a swimming pool of slick fluids.
It wouldn’t be an exaggeration to call it an onsen pussy rather than a sterilization pussy!
I stirred her insides wildly with my cock as if I were swimming through her.
Stir! Stir!
Exactly like mixing syrup and toppings into a drink at a café!
“Huooh♡!? Ungh♡?!”
She still seemed completely unaware of what I was doing to her pussy.
Every movement caused the love juices packed inside her to squirt out like urine under pressure.
I kept stirring and thrusting until I could no longer endure the scorching heat and insane tightness of this open-air onsen pussy (sterilized pussy/hole).
“Krrgh! Cumming in this open-air onsen pussy! Spread that cunt wide, you bitch!”
I grabbed Yuna’s arms and drove my hips forward with everything I had, slamming my cock toward her womb as if trying to violate it completely.
Thud! Thud! Thud! Thud! Thud! Thud!
“Uht? Uooh? Oohk! Oghok! Ok!”
“Cumming! I’m cumming! Injecting a massive load of massage cream into this open-air onsen pussy!”
“Take every last drop and don’t let any leak out!!”
Pulling her arms back with all my strength, I pressed my body flush against hers so tightly that not even air could escape her pussy. I put my full weight on her, crushing her down.
Spurttttt♡! Spurt♡! Spurtt♡! Spurrrt♡! Spurt♡!
The semen erupting from Myungho’s cock shot upward like a geyser, flooding her womb!
Spluuuuurge!
“Oghok♡! Uooooohk♡!”
Her womb battered by thick ropes of semen, Yuna came hard and squirted her love juices like a fountain.
Myungho’s cum completely filled her womb.
The fresh load, aside from what had already been near her entrance, was sealed tight by my cock and couldn’t escape.
Gush! Gush! Gush!
My cock, savoring the lingering heat of her pussy, slowly pumped out the rest of the semen still inside it.
I could feel her pussy filling up with my cum.
Even though it wasn’t my first load of the day, the amount was far greater than usual. I basked in an insane, blissful sense of satisfaction.
Perverted trait awakening is the best…!
Special Dick
Shh! I’m in the middle of sex!
Acquiring the trait was nice, but I still had work to finish.
When I pulled out, her pussy clung to my cock as if reluctant to let go, stretching tightly with a lewd, sticky grip.
Uwooht.
The incredible tightness of her pussy following my cock sent extreme pleasure surging through me as I slowly withdrew.
Whew… That was close. You erotic little pussy.
Pop♡!
With the cock plug removed, thick semen spurted from her pussy while more slowly leaked from the entrance.
The sight of my cum flowing out of her gave me a perverse mental thrill.
“You sloppy erotic pussy!”
I shoved her panties deep into her pussy to seal the cum inside, then yanked the wet, torn, sweat-soaked leggings back up so tightly they clung to her like a second skin.
“Kyaaak♡!?”
The roughly pulled-up leggings pressed so tightly against her pussy that it was almost completely visible.
“Don’t take that off until the massage cream is fully absorbed.”
Where do you get off seducing my cock by leaking semen from your sloppy hole!
It somehow made her even more arousing, but the sense of conquest felt good.
I wasn’t sure if the semen would actually be absorbed, but I ordered her to keep it stored inside her pussy.
“Huu… Hic… Yes…”
Yuna had agreed to turn her pussy into a semen-pickled vessel!
“If I gave you a massage and even sprayed you with cream, you should say thank you.”
The overwhelming mental pleasure from humiliating her made precum leak from my cock.
Psssshhhhh! Pssht!
She, too, felt an incredible wave of humiliation and shame, causing her sealed pussy to vulgarly spray love juices once again.
Still leaking heavily, she answered.
“…Thank you for the heat massage… Thank you for spraying me with cream…”
Ah.
Disappointing. It wasn’t quite satisfying. I ordered her again so she would spit out something even more shameful.
“Include the part where I put it in your hole. Since I generously filled you with precious cream, say it sincerely, kindly, and from the beginning again!”
Since she had chosen to call it a “hole” instead of a “pussy,” I decided to play along with her rationalization.
“……………..”
What came back was not an answer but silence.
Was it too much? That can’t be.
Myungho wondered if the training play had been too early despite all the harsh things he had already done and felt a twinge of regret.
But soon after, she spoke.
“Thank you for bestowing a heat massage upon me… Thank you for spraying so much cream…! Thank you for putting so much cream in my hole…! Thank you for sealing it so nothing can escape…!”
Perhaps thanks to the achievement effect, she had fallen far more easily than Myungho expected.
There was nothing to be grateful for; if anything, she should have been cursing him and reporting him.
Yet she expressed her gratitude in a lovely, sweet voice for the fact that he had used her like a toy.

Admiring her lewd rear view while listening to her words of thanks, my cock throbbed so hard I nearly came on the spot.
Satisfied with my successful training of her, I checked the trait I had just acquired.
The dick-enhancement skill I had been anticipating ever since I realized it belonged to the erotic category! It would feel incomplete without this, wouldn’t it?
