The Sensitivity Multiplier
"Aiiiiik—!"
Wi Seoyeon's attack on me had failed.
If she could move her body at all, she'd have tried to kill me again. Of course, with the contract in place, that was impossible.
Now, just like Seol-hwi before her, Wi Seoyeon was going to have a vow-mark engraved on her lower abdomen.
-CHIIIIIK!
"Kkuuuuk—!! Wh, what the hell is this…?!"
"What do you mean, what? You're the one moaning like a bitch."
"Kkuuuuk—!! You rotten fuck—! Undo this right now!"
Wi Seoyeon was still half out of her mind, cursing me out.
"I'm getting real tired of this. There's a limit to how much I'll put up with."
"You goddamn dog!"
I didn't care for her shrieking obscenities at me.
I'd originally planned to just take her once, like Yeoryeong's scheme suggested. But if she was going to act like this, things were different.
"W, what did you say?"
She tried to look flustered, but her body moved in accordance with my words.
The clothes she'd put on so carefully fell from her body, and Wi Seoyeon was naked in an instant.
"…Don't look! You—how dare you—do you really think you'll get away with this?!"
"Obviously I will."
As long as I didn't invalidate the contract, Wi Seoyeon couldn't attack me in any way. From now on, the only thing she'd be doing was getting eaten by me.
"Kkuuuuk—!"
The spot that had been rubbed raw was now exposed. Her raspberry-colored nipples and a straight little slit stared back at me like they were putting on a show.
"Hey. Got anything to say to me?"
"…No. I'd rather die than beg you for mercy."
"No? Then I guess I'll just eat Yeoryeong."
"Y, yes, Master."
She didn't even seem to understand how she'd ended up in this state. Yeoryeong offered to service her pussy on her behalf and even made a slave declaration for her.
"W, wait! Lady Chunho said she wouldn't touch me!"
"Fuck that. I'll do whatever I damn well please. And isn't the thing you said to Master way too short?"
"…"
I aimed my cock at Yeoryeong's pussy again, just like before. Wi Seoyeon's face had gone the color of a ripe plum.
"…M, Master…"
"What? Can't hear you."
"…Master. Please look at Lady Chunho."
She squeezed her eyes shut and spoke through clenched teeth, as if trying to refocus the resolve she'd shown a moment ago.
"Is that all? Suck it better."
"…Hah?"
"Suck my cock."
She had to prove that resolve somehow, right?
"…I understand."
Wi Seoyeon dropped to her knees and adjusted her mouth to the height of my cock.
"Th, this is so big… how am I supposed to…"
"It's fine. When I tell them to do it, they all manage pretty well."
-KUUK!
She took the tip into her mouth.
"Uuup!!"
"Don't bite down. Every time you scratch me, it's one slap to Yeoryeong's pussy."
"…!"
She flinched at that, and I grabbed her head and pulled her closer. When my cock hit the back of her throat, she gagged, and she started slapping my thighs with both arms.
"It's not even halfway in yet. Tilt your head up a little."
"Uuup—!!"
This straightened the passage all the way to the throat. To push my cock all the way in, this was a necessary step.
"Relax."
-KUUUK!!
"Uguuup—!!"
I kept pushing it in. This was my first time handling a woman this roughly, but it felt better than I expected.
-CHUUUP!
"Hnnk… what the hell? You're pretty good at this."
After a few movements, the urge to cum hit me fast. The force of her throat fighting to breathe created quite an alluring grip.
"Uuup…"
The problem was that Wi Seoyeon's prayers seemed to be blocked, and she was losing consciousness.
First I'd finish, then I'd eat her pussy too.
-SWIK! SWIK! SWIK! SWIK!
"At least one shot first!"
"Uguuup!!"
-BWEURRUK! BWEURK!!
I delivered my cum directly into her stomach. Even as I did, her eyes rolled back and only the whites showed.
"Uuup! Kkuweeeek!!"
When I pulled out, she kept dry-heaving. I'd shoved the back of her throat that hard, so the foreign feeling must have been intense.
I wondered if I'd gone too far, but the moment I thought of everything Wi Seoyeon had done to me, any guilt vanished instantly.
On the contrary, I only wanted to be rougher from now on.
"Seoyeon-ah, how's the taste?"
"…Lady Chunho… this is…?!"
"Sorry about that. What you drank yesterday was actually Master's cum."
…What? Did she really feed the cum from that cup to Wi Seoyeon?
As expected, the cunning of a nine-tailed fox couldn't be ignored. She did things that no ordinary thinking could follow.
"…How could Lady Chunho do something like that…?"
"I'm sorry."
Distrust was now planted in Wi Seoyeon's eyes.
"Enough. Now spread your pussy."
"Hnhk… I understand, Master…"
Her sweat-soaked body lay on its back. Her legs spread on their own, and her hands grabbed her vulva, pulling it open.
"Hnhk… it's, it's ready… Master…"
The instructor who'd looked at me with disgust just days ago was now showing me her pussy.
"Fuck, that's hot."
"…"
No answer. She just turned her gaze away from me and let tears fall.
"Master, hold on a moment."
"Hm? Why, Yeoryeong-ah?"
-murmur murmur…
"…You mean it's possible?"
"Yes. Since it involves exercising full control over the body, I figured it might work."
What Yeoryeong had suggested was something I'd never considered. It wasn't something I thought was even possible.
"Might as well try it once."
If it failed, there was no risk. At least trying wouldn't hurt.
"Master…?"
When I suddenly stopped, Wi Seoyeon stared at me with a confused expression.
Why was our Lady Chunho going to such lengths to torment her?
I activated what Yeoryeong had said before. "Remove gravity." Normally, impossible commands like that wouldn't make spirit energy move, but right now, my spirit energy clearly acted on Wi Seoyeon.
"Hnnh—! W, wait, this is weird…!"
"It worked, Master."
"…It actually worked?"
I'd have to see from here whether the sensitivity multiplier was really at ten times.
"Master, hold on! If you put it in now it'll be too much…!"
"Shut up. Spread your pussy nice and wide."
I lined up the glans with her entrance.
-CHILK!
"HNGIIK!! Shit, stop! This is too much!"
"You're talking like a bitch again."
"No, I'm sorry! This really doesn't feel right…"
-PUK!
The glans slipped into her pussy.
"HYYYAAAH!! Hey! You damn psycho, Hwan Hyun, pull it out!!"
She was so frantic she was mixing in the most vulgar profanity imaginable, trying to push me away. But her body, already being consumed by pleasure, couldn't do it.
"Now you're not even trying to hide what you really want, are you?"
"W, wait…!!"
I ignored her and adjusted my stance. Just like before, I straightened the path to the cervix and angled myself so that with just the weight of my body, I could push all the way in.
"I'm sorry, I'm sorry! Master! I'll spread my pussy for the rest of my life! I'll apologize for everything I've ever done to make your life hell!"
"What am I supposed to do with that. You don't want to have sex?"
"Just do this for me! If you go any further I don't know what'll happen…!"
"Hmm… would it really be like that?"
-KUDUDUDUK!!!
Her desperate plea radiated through her entire body. Was the sensitivity multiplier at ten times really that powerful? In manga it was usually 3000 times.
-CHIJIK!
I pulled my hips back. Until the glans caught on the entrance of her pussy.
"T, thank you, Master…!"
"Hey. Wi Seoyeon."
"…"
The fact that she immediately bit her lip told me she still wasn't used to speaking casually with me.
"There's one thing you're mistaken about."
"…Yes?"
"Originally, this kind of thing… is all about gaining thrust power."
"…You don't mean…?!"
-KUDUDUDUK!!!
I pushed my cock in with both my body weight and my strength. The hymen vanished in an instant, and with all that force, I slammed into her cervix.
"!!!!!!"
-SHIIIII…"
"Oh my."
Lady Yeoryeong covered her mouth at the sight of Wi Seoyeon, whose entire body went rigid.
"Kkuuuuk! What the hell is this grip?!"
The feeling at her cervix wasn't even something Seol-hwi, with her weaker pussy, had experienced. Wi Seoyeon was the first woman to keep cumming from just one session.
"Ohh… ohhhohhhohhhh…"
She moaned like someone who'd been fucked all night. Juices kept flowing from her pussy.
-PUKCHIK! PUKCHIK!
I kept ramming my cock into the already soaked pussy.
Wi Seoyeon was already unconscious, but her convulsing pussy only felt good.
-PAANG! PAAANG!!!
"UHRAH! UHRAH! Going crazy on the first time, you bastard!!"
"Ohhh… ohhohh…"
I felt her pussy biting down on my cock and thrust in without pause.
-PANG! PANG! PANG! PANG!
"Mmm… c, can't… hold it…?"
"…"
Wi Seoyeon, predictably, had no answer.
"Kuuuuk—!!"
-BWEURIT!! BWEUR!!
And then, cum gushed out. Through her pussy, which clamped down on my cock without end, I filled her womb with my seed.
"Hhhhaa…"
"…"
Was the stimulation too strong for a virgin?
Wi Seoyeon stayed collapsed like that until the next morning.
-CHAP! CHAP! CHAP!!
"Eeeek! Stop! Unconscious pussy going into another orgasm!!"
Of course, I'd been eating that pussy all night.
-CHUUUP!
"Haaah… thank you for using my pussy, Master…❤️"
I only used Yeoryeong's pussy when I was about to cum. Since Wi Seoyeon was unconscious anyway, this side was better for enjoying the reactions.
"You can stop the act now. She's passed out."
-Sssik.
I told her she didn't have to keep using honorific speech with me, but Yeoryeong just giggled.
"No, Master. After spending a night like this, it feels like this is what I was meant for."
"Hm?"
"From now on too, I'll serve you as intensely as I did tonight."
"…Really?"
"Yes~ Master, please use this perverted Yeoryeong's pussy whenever you want…❤️"
Wi Seoyeon's reaction suddenly came to mind. How could she curse the person who'd raised her?
'Damn. Getting hard on the person you raised is even weirder.'
The real problem was probably Yeoryeong, wasn't it.
"Uuuhh…"
Even Wi Seoyeon, who'd been tormented by my cock all night, might have agreed to that now.
