Spanking
"Y-you're going to hit my ass...?"
Jung Sujin's face twisted with the kind of bewilderment you'd expect. Of course it did. From the day she'd awakened her powers, nothing like this had ever happened to her.
"That's right."
"I mean... isn't that a little much? I'm a woman. And you're a man."
"Then let me ask you something. Do you think gender exists between a trainer and their student?"
Sujin looked like I'd just taken a hammer to her skull. I'd been talking out of my ass, honestly.
"Th-that's not it at all! I spoke thoughtlessly. I'm sorry, Trainer Baek Sehyun."
I decided to drive the spike in deeper. A little more gaslighting and I could snap her will for good.
"You don't actually think you're the idol leading the Korean music scene right now, do you? That's arrogant. You need to remember what hunger feels like."
"Hahk..."
"Artists always produce their masterpieces when they're poor. You need to learn how to go back to the beginning! Do you understand me?"
Okay, even I had no idea what I was talking about. Why was I rambling like this? Seriously...
"I understand what you're saying, Trainer. It's been five years since I debuted, after all. I've been losing that heart I had at the start, little by little."
Amazingly, Jung Sujin looked genuinely moved by my complete nonsense.
Yeah, she was not normal. A regular person would've gone, Who the hell is this nobody running his mouth? and wouldn't have given me the time of day.
"Good. Now that you understand, what should you do?"
"...Understood."
Sujin still looked unconvinced, but she folded in the end. She sank down onto both knees and looked up at me, glittering eyes holding mine in a long, steady stare. Then she turned herself around and pushed her ass out toward me.
Holy shit, it's huge.
I was only seeing it properly now, but Jung Sujin's ass was enormous. Even bigger than Baek Hanyoung's. She looked about five-foot-nine, and with an ass that size I had no idea how she even managed to dance.
I ran my palm lightly over the ass she'd offered up, then let my gaze linger on her underwear. Plain white panties.
I'll have her wearing something way sluttier later.
I was going to turn Jung Sujin into a house for my cock. That meant no more ordinary underwear, ever. She'd wear what I wanted her to wear, and I'd be the only one who got to see it. The thought of dyeing this beautiful body in my colors sent a thrill through me I couldn't quite suppress.
Calm down... we haven't even started yet. Getting ahead of yourself this early is way premature.
What I was doing right now had to be a fight for survival. If I started thinking of this as nothing but fun, I was in trouble.
"I'm going to spank your ass now. How many do you want?"
"O-one..."
"One? No. That's way too few."
"Theeen... I'll take three."
"Good. Still not getting it, I see. We'll start with ten. Understood?"
Sujin's body gave a little shiver at that.
Of course, getting hit by me wouldn't actually hurt her. I had a pathetic body that couldn't even lift a light pair of dumbbells properly. But the fact that a man she'd met today was about to strike a private part of her body she'd never allowed anyone to touch — that had to be deeply humiliating.
Let's make that feeling explode.
I raised my palm high. Then I brought it down hard across those white panties.
A juicy crack rang through the entire practice room. A deeply satisfying sound.
"Euhiiik?!"
My skill worked just fine even on an S-class Superhuman. The moment my palm connected with her ass, her waist sank toward the floor.
"That's one."
"Euhii... w-wait a second. Something feels weird!"
I didn't go easy on her at all. I cracked my palm down again. Another juicy slap rang out, still loud even through the panties.
"Panties off."
"W-what...?"
"You planning on being uncooperative? Don't talk back before I start adding more."
I wanted to swing my palm against bare skin now. I wanted to strike that massive ass and wring even louder moans out of her.
"Okay... I-I'll do it! Just please don't add more!"
Good. She was still cooperating.
She reached back with both hands and groped downward, fingers sliding and searching until they found the waistband. She gripped it hard and peeled it down in one long pull.
A snow-white ass came into view. Just looking at it made me want to hit it.
What a filthy ass.
By this point a giddy pleasure was starting to bloom in my chest, but I crushed it immediately. This was work. Sure, I was having sex left and right, but the moment I told myself this was something I didn't want to do, I felt the lecherous urge fade just a little. Good. Let's do this.
"That's two so far. Eight left. From now on, you count."
"Y-yes...?"
"If you miscount even one, I'll add that many more."
I stroked slowly over her ass, then lifted my palm and smacked it.
"Kyaaaang!"
"Oh? Not counting?"
"Th-threeee!"
Jung Sujin's body completely collapsed. She couldn't even hold her posture — she was plastered to the floor, trembling all over. Even so, I didn't hesitate. I raised my palm and spanked her ass, smack after smack, and her body jerked with every blow.
"Count!"
"Yeees! F-fiiiive!"
"Getting slower, are we? Fine. One extra!"
"Euhhaat!? Th-that's too meeeean!"
"Don't talk back!"
A woman who made the entire South Korean government scramble just by existing was right now moaning from nothing more than my palm. How deliciously transgressive was that? Someone who could kill me with a look was falling deeper and deeper under my spell.
"You're not showing even a hint of remorse! You pathetic bitch."
"Th-that's not truuue... I-I'm trying riiight now!"
"What? Then what's this?!"
I wrenched her ass cheeks apart. Her lewdly flushed pussy lips came into view, and between them, cunt juice dripped steadily, staining the floor. Clear evidence that she was getting off on being spanked by me.
"Getting off on having your ass spanked... you really are a thoroughly filthy bitch."
"Hiiiik... this isn't even my wiiiill..."
"This won't do. You need to be hit more."
I raised both palms high. Then I brought them down without mercy, pounding her like a drum. Smack! Crack! Smack-smack! I played her like an instrument, keeping the rhythm, and Jung Sujin was already completely spent. She'd collapsed onto the floor. All she could do was twitch in time with my hands.
I was probably the first person in history to spank an S-class Superhuman's ass... and the only one who'd ever exhausted her like this.
"Hooo... how many was that?"
"Euhhng..."
"Oh? Not answering?"
"Teee... n!"
I didn't know the exact count either, but I knew it was well past ten.
"You stupid bitch. You think I only hit you ten times? Not even close. You didn't count properly... Fine. We'll stop here for now."
"Y-yeees..."
I wanted to keep going, but my hands were stinging too much. Jung Sujin's ass had turned bright red. There was no way my own strength could have left a mark, so it was probably the skill's doing.
"Ten-minute break. Then we start again."
Jung Sujin, lying on the floor, didn't answer. That was fine.
Time was on my side.
S-class Superhuman Jung Sujin was reeling from an emotion she had never felt before in her life.
Am I a filthy idol?
She had always firmly believed that debuting as an idol meant suppressing every last desire. That was why, whenever a former member so much as masturbated, she had killed them on the spot.
And yet right now, Jung Sujin had felt a faint pleasure. What on earth was happening?
I've been disqualified as an idol...
Clutching her stinging ass, she slowly began to dance the choreography she'd watched in the video. But she still couldn't see much progress. The spot she'd been hit was starting to burn.
But that man is truly remarkable.
Amazingly, Jung Sujin had come to genuinely respect Sehyun in his trainer disguise. She wasn't sure whether he actually had any skill, but of every trainer she'd ever had, he was clearly the most passionate.
The so-called elites she'd met before had all trembled and walked on eggshells around her. This trainer, though — he wasn't intimidated in the slightest. He'd even beaten her.
If I stay under him... I can take the next step forward.
She found herself looking forward to Baek Sehyun's next training session more and more.
Meanwhile, the fluid leaking from her secret place traced down her legs and dripped onto the floor. Plip. Plip. Every time Sehyun crossed her mind, the dripping grew more frequent — not that anyone needed to point it out.
