Hypnosis Feels Like a Lie
"Haaah...!"
Ha Eun-ju planted her forehead against the open window frame and let out a long, deep sigh.
Somewhere along the way, Oppa had started treating her as if she weren't even there. She'd been so sure she'd finally gotten hold of a weakness of his—and all she'd meant to do with it was stretch, little by little, the time she could spend with him.
"At this rate... I'm the one whose weakness got caught...!"
It felt exactly as if her sister had stolen Oppa out from under her. All she'd hoped was that this might be her chance to shave off a little of those two's time together—the tiniest little bit—and spend it on herself. Playing along with that ridiculous prank of a hypnosis app had been for that reason alone.
She was the one who had told him to do to her precisely what he'd done to her sister. And that "command" had turned out to mean stripping her own clothes off and letting him knead her breasts like a toy.
"What on earth is Unni thinking...?!"
Should she, at least, have been the one to tell Oppa to stop? Or should she have been honest and admitted she wasn't hypnotized at all?

Her head was a tangled mess. It had to be because that raw, salty, indecent smell of his still filled the room.
On the phone screen he'd held up to her, after about five seconds, a line of text had surfaced.
She'd been certain he was only joking. To think that pure, innocent face would give her a command like that.
"...This is insane. It really is..."
Remembering how he had filled her mouth, Eun-ju brought a fingertip lightly to her lips. And she'd been drenched in his cum on top of it.
"And then he has to go and wipe me off so gently. What was that about..."
When had those hands of his gotten so rough? The Seo Geon-woo who had cleaned her up was not the one she used to know.
"Hnn...!"
From the moment his hypnosis took hold, the inside of her panties had been a complete wreck. If that "command" had told her to pull her pants down too—
"I would've taken them off, wouldn't I...? Haah...! What am I even thinking?!"
Eun-ju eased her door open with painstaking care and checked the living room.
"It's quiet..."
A change of underwear clutched secretly in hand, she bolted for the bathroom.
I yanked my underwear on and asked.
"D-do you remember...? Fr-from when you were hypnotized...?!"
Cold sweat slid down my spine. I could feel every inch of it. If she remembered the hypnosis, it wouldn't be strange if she murdered me at any moment. Was that why her face was so red—why she was this angry?
"Sh-shut up. I don't exactly r-remember. I just... when I opened my eyes! You were shaking me like crazy! Right?! A-and, what was it, the other thing..."
"Y-you weren't wearing any clothes... Yeah."
"Th-that's right! A lady's asleep without her clothes on, and you go and put your hands on her like that?! How is that okay?!"
"Y-yeah... haha. R-right."
How furious did you have to be to stammer like that? So, lining up what she was saying: she knew she'd been hypnotized, but she didn't remember any of what had happened during it.
"Then... why are you asking me to hypnotize you...?"
"What?!"
"H-huh? Did I s-say something wrong?"
"No! What—what is it. R-right! Once I got hypnotized, I forgot everything before and after! Yeah! I just want to forget that hideous thing as fast as I can...!"
"You do...?"
Hideous. And here I'd already been in Eun-ju's mouth.
"Got it?! Hurry up and hypnotize me. I'm saying it again—I don't remember anything from when I'm under, so you can't just g-go touching me and d-doing that...!"
"Yeah."
"M-my chest, or... d-down there, either..."
"Huh? What'd you say?"
"Nothing! L-let's just start. If we wait any longer, it probably won't get erased. It'll just stay in my memory."
She scrambled up onto the bed. My eyes catching on her from behind—no, on her ass—wasn't because I was a pervert. It was only natural.
"Wh-what are you doing? Hurry up and get over here."
She patted the mattress. She'd told me to sit in front of her; now she swept her hair back with her fingers, cleared her throat with a little ahem, and straightened up.
"I-I'm ready."
Haah. Hypnotize her again, she says. If I put her under in the state I was in now, I honestly had no idea what I'd do. I hadn't lived out every fantasy, but I was a man who now knew exactly how electric it was to share a body with a woman. If I asked myself whether I could really keep my hands off Yeon-su once she was hypnotized—
"Hey, what are you doing?! Why aren't you sitting down already!"
"Ah, yeah. Sorry."
You're dead. The second you go under.
I sat down in front of her at once. Things were already getting tight inside my underwear.
"I'm doing it? You're ready, right."
"Yeah...!"
I opened the hypnosis app. The taegeuk spiral—the swirling yin-yang—began to turn.
"Okay. Watch this carefully."
I held it up to her. Count to ten, and then—
Thuk.
"Huh...?"
The moment she looked at the spiral, her head dropped. She was under.
"Th-the power got stronger...!"
Just like the hypnosis apps in dirty stories and adult comics, mine seemed to be getting stronger little by little. No status window or anything else had appeared, but hypnosis the instant she laid eyes on it? The hypnosis app was the best.
"Ahem. Ahem! Good. Ha Yeon-su. Are you ready to receive a command?"
"..."
"Huh. Not answering."
"...Nnh...? A-am I supposed to answer...?"
"Yes! Obviously. Talking to you counts as a kind of command."
"Ahh... nnh. I'm sorry..."
As expected. Hypnotized Yeon-su turned shy. Look at that—her face was already going red.
"Right. Barging into Master's room so brazenly..."
I reached out and pulled her into my arms.
"Ha Yeon-su. You need to be punished a little, don't you."
Held against me, Yeon-su's face flushed so red it looked ready to burst. Her hands, with no idea what to do, stayed clenched into fists near her chest.
"You're not heavy, so just relax and lean on me."
She'd been clinging in an awkward half-pose. It seemed like a natural movement—trying not to put too much weight on her master's arms. On mine.
"...Okay."
Yeon-su drew her legs in and buried her face deep against my chest. I wished she'd act this cute normally, too, but I knew a person's nature didn't change that easily.
"Good. How should I punish you today?"
"...A-are you asking me?"
"Yeah. I don't really know how."
Everything I knew, I'd learned from porn. The "punishment" they showed in those was pretty sadistic, and I'd heard that kind of play took a lot of preparation. I couldn't leave marks on her while she was hypnotized. I couldn't let it scar.
"How do you want to be punished?"
Once she was under, she seemed to answer a question exactly as it was asked. Sweet, hypnotized Eun-ju had already taught me plenty.
"I... I don't know..."
I don't know. She really didn't, then. Yeon-su seemed popular—was she actually that inexperienced?
"Hmm. For now, mind taking your clothes off? I think I need to feel your chest while I think it over."
"..."
"Tsk! Answer!"
"...Y-yeah."
She squirmed her way out of my arms. Turning her back to me, she glanced over her shoulder, then peeled the loose white T-shirt off in one go and set it aside.
"Yeah... you really are pretty..."
At my words, Yeon-su ducked her head. Her ears were red enough to burst, and somehow that made me want to tease her a little meanly. Maybe that was why. Stacked on top of the confidence I'd picked up from Eun-ju, words I never imagined I could say jumped out of my mouth.
"Take the pants off too."
"Huh...?"
I was a little embarrassed myself, once I'd said it. Telling Yeon-su to take her pants off—I might as well tell her to take her panties off next.
"Just a second..."
She climbed down off the bed. She stood at attention facing me, then fidgeted with the waistband of her pants. Without meaning to, I held my breath and watched her. Meeting my eyes, Yeon-su dropped her head and let out a trembling moan.
"Huuu..."
That she could still feel shame even under hypnosis was, in one sense, pretty inconvenient—and in another, good enough to give me a nosebleed. That sharp-tongued Yeon-su, blushing, and in the end actually pulling her pants down. I'd have to stash tissues all over the room if I didn't want to bleed out.
Very slowly, Yeon-su bent at the waist and lowered her pants. Inside the gray dolphin shorts—a match for Eun-ju's, by the look of them—were gray cotton panties of the same color.
"Ooh...!"
The sound of admiration escaped me on its own. Gray cotton panties were the dream of so-called guys who know a thing or two, weren't they? I was no exception. I wasn't exactly a guy who knew a thing or two, but I knew what gray cotton panties meant.
"If those panties get wet, it shows right away. You sure that's okay?"
"...Huh...?"
"Well, there's no okay or not-okay about it. You won't remember. I'll change your panties before I snap you out of it."
Cleanup, planned to perfection. Now all that was left was to enjoy my happy time with her.
"Come here."
Still sitting on the bed, I leaned back against the wall and opened both arms. Meeting my eyes like that, Yeon-su's gaze somehow set my heart racing.
"Okay."
Yeon-su gave a small nod and climbed onto the bed. She turned, pushed her hips back, and inched closer. When our thighs touched we both flinched a little, but I didn't care—I pulled her in, so the girl who had come into my arms couldn't get back out.

"Nnh...!"
"Embarrassed?"
I buried my face against the nape of her neck. Yeon-su's scent wasn't exactly like flowers, but it was a warm smell all the same.
"Snff... Haaah—. Insane tonic."
"Hehe. What are you even saaaying..."
Only now did I understand that a voice this feminine could come out of Yeon-su. I wrapped both arms wide around her and drew her in.
"If you were like this normally, how good would that be..."
Even now, all I could do was say what I really meant. I had never once considered Yeon-su as someone to date. On paper, we were family. But if we hadn't been?
If she had only spoken to me, I wouldn't have slept that night. That was what Yeon-su was to me.
"It really... feels like a lie."
"Nnh... I know..."
I lifted the face I'd buried, just a little. Had Yeon-su just agreed with me? That it would be nice if she were like this normally, too?
She was hypnotized. Matching Master's mood was only natural, so of course that was the answer she'd give.
Chu.
I pressed my lips to the nape of her neck.
"Haah...!"
Yeon-su's shoulders hunched. And then she took my hand, drew it in, and set it on her chest.
