Hypnosis Was Pretty Good
"Hey... Ha Yeon-su...!"
Please, God. If this is a dream, don't let me wake.
When had I ever actually seen a woman's bare breasts with my own eyes? Right now. This was the first time.
It wasn't a glance stolen by some lucky accident, and it wasn't something I'd paid a set price to see through anything illegal. She had listened to me and taken it off herself.
There was no way a hypnosis app that actually worked could exist in this world. It couldn't. So why was Yeon-su showing me her chest?
One: the hypnosis app was the real thing, and Yeon-su was under. Two—there was no two.
The hypnosis app was the greatest.
I took my time looking at her. The breasts themselves were small, yes, but the areolae and nipples were a clean, pale pink, and set against that milky-white skin the whole of it was enough to leave me grateful. Every time she drew a breath, her chest swelled, just a little. Even hypnotized she seemed to feel the shame of it; her cheeks and ears had gone past flushed, and I could have sworn the heat of them reached me from here.
"Yeon-su. Can you hear me...?"
Unlike some cheap hentai, her eyes hadn't lost their focus. When I leaned my face in close, I could actually see her pupils snap tight.
"Huh. Weird..."
I waved a hand in front of her face. I called her name again and again. Nothing. No particular reaction at all.
Gulp.
Which meant I was safe. You do not, under any circumstances, spit on a meal that's already been set in front of you. Which meant I absolutely had to touch these perky little breasts.
"You'd agree, right? If I didn't touch them, you'd call me a dickless loser. Wouldn't you?"
"..."
Yeon-su didn't answer. If someone asked whether I had a moral compass, I'd say I did, and also that I didn't. If they asked whether I feared God, I'd say I did, and also that there was nothing to be done about it.
I scrubbed my strangely sweaty palms together and dragged them hard over my thighs. Twenty-three years of never once having a girlfriend. And that was probably because Ha Yeon-su had been glued to my side the whole time, so I'd never had a chance to talk to any other girl. The fact that I was touching a breast for the first time today was entirely her fault. That's what I told myself.
And then I touched her.
"Oh... son of a... bitch...!"
She was softer than I'd imagined. A man's body simply doesn't have a lump of pure fat like this, so the feel of it was utterly strange, and utterly soft. Yeon-su's chest, the one I'd always thought of as small, didn't disappear into my hand the way I'd expected. The nipple against the center of my palm wasn't hard so much as yielding, the texture of soft jelly. Goosebumps rose along her shoulders, fine enough that I could see them. When her mouth twitched, I genuinely prepared to die. But she only reached back, braced a hand on the bed, and otherwise didn't react at all.
The power of hypnosis was honestly terrifying.
"So soft..."
I moved around behind her. To knead her breasts properly, I circled my arms around her from the back, as if I were pulling her into a hug. I'd always been close to Yeon-su, but being pressed against her like this felt strange in a way it never had. We used the same shampoo, and still her hair seemed far more fragrant. I drew a deep breath. Burying my face against the nape of her neck, I closed both hands gently around the breasts that filled my palms. I caught each small, cute nipple between thumb and forefinger and rolled my fingers with only as much force as I thought wouldn't wake her.
"...They're getting harder."
In the dead of winter, when the cold bit hard enough to set me shivering, I'd seen my own nipples stiffen. But this was May, warmer than any other time. Even so, Yeon-su's nipples were hardening—only a little at a time, but unmistakably.
"Nnh..."
At that faint moan I thought my breath had stopped entirely. I'd completely forgotten that a person under hypnosis could still make a sound, and the fear that she might have woken washed over my whole body. Her shoulders trembled, barely, and a moan so soft I could hardly hear it refused to stop. Because I'd kept touching her with my death already accepted. If she was going to wake, let her wake. If I died with her breasts in my hands, I'd have no regrets left in this life.
"Hnnn..."
Her moans were getting louder. Thinking I didn't have much time left to live, I put more strength into my fingertips. Common sense said the way to survive was to let go this instant and get out of the room. But losing a once-in-a-lifetime chance because I'd been shoved around by fear—that was far more frightening, and far more shameful.
"Haa—ah...!"
My fingers tightened before I meant them to, and Yeon-su threw her head back with a moan. Her hair spilled over my shoulder, and then she was resting her head against me. It wasn't only her hair tickling the tip of my nose. Yeon-su's scent. The smell of her skin, or whatever you wanted to call it. I'd never imagined it could be this thick. Today, every tiny thing about her came through sharp and saturated.
"Haa... hnnn..."
Her head shifted from side to side, tickling my shoulder. I used that tickle as an excuse to tease her even more meanly.
"Haaa... haa..."
I couldn't have said how much time had passed.
"Haah... nnh..."
Yeon-su had started moaning outright. It had already been a while since the gaze of the girl leaning on my shoulder had turned toward my face. She kept flinching, too, as if something about it didn't sit right. By then I was rolling my fingers like I meant to pinch her nipples off, and whenever I closed my hand around the whole of a breast, Yeon-su even lifted her hips a little.
"S-stop..."
Half an hour must have gone by. It was the first time she'd opened her mouth. I startled at that melting voice and let go with both hands.
"Y-Yeon-su?"
"Haa... hoo..."
No answer came back from Yeon-su, who was panting without pause.
"Yeon-su??"
I tried to move around in front of her. The breathing she was dragging in without a word was rough enough to worry me. And then a problem presented itself.
"Shit...!"
It felt exactly like I'd had a wet dream. I could feel the precum gone slick and sticky; the inside of my underwear was probably a disaster.
"Tch."
What else was there to do? Once Yeon-su's hypnosis wore off, I'd have to shower, or change, or something.
"Yeon-su, you okay?"
I sat down in front of her again. And for a moment I think my breath stopped.
I already knew she was pretty. Her skin was fair, and looking at her, I could see exactly why that narrow waist had earned her the nickname ant-waist. Sometimes that fiery temper of hers was even something I could lean on. But—
"Wh-why are you looking at me like that."

With a gaze that soft turned on me, my head went blank.
"Geonu..."
"Yeah...?"
I waited for the rest. Her face said something was wrong, but I waited anyway. Her eyes went up. Then down. Her lids shut hard, and opened again, very slowly. The rough panting had quieted before I noticed, and a long sigh slipped out of her. Yeon-su swallowed, and slowly began to speak.
"Geonu, I feel all hazy... L-like I've been hypnotized or something..."
"...R-really?!"
I didn't let that slip past me. She was trying to come out of it, I was pretty sure. I hurried her down onto the bed, pulled the blanket out from under her, and spread it over her. And then I left behind a piece of evidence she would have no way to dodge.
"Hey, hey, hey, hey, hey!!! Ha Yeon-su!!! Why are you sleeping in my room!!!!"
I shook her awake without mercy and drove it home: why were you asleep in my room? Pillow, blanket, mattress—everything she was lying on, I shook with everything I had.
"Stop...!"
"Huh?"
"I said stop shaking me, you dumbass!!"
Smack!
"Kids, what's all the fuss? Don't fight—"
At the shouting, Auntie's voice carried in from the living room. Yeon-su and I scrapped like this several times a day, so she wouldn't think much of it. The problem was that Yeon-su seemed angrier than usual. I clutched my burning cheek and asked.
"Wh-why are you mad...!"
"Wh-why do you think! Waking me up, fine, but you could at least do it gently! I thought I was gonna die, I got so dizzy!"
Yeon-su yanked the blanket up and vanished under it.
"S-sorry..."
Fair enough. If somebody woke me that roughly out of a dead sleep, I didn't think I could have held the swearing in either. I scratched my cheek with a fingertip and took a step back. Her tank top, left at the foot of the blanket, I folded once and set beside the pillow.
"Yeon-su. You need anything...?"
"Get lost. Dumbass."
"Quit swearing at me."
"I just woke up and I'm completely pissed. Just go."
"...Fine. If you need something later, say so."
"..."
That was the last conversation Yeon-su and I had. Two days passed, and she wouldn't so much as look at me. Whenever there was something that actually needed saying, she told me, curtly, to use the messenger.
"Haa...!"
I sat at the dining table with my head in my hands and tried to figure out how to fix this. The problem was whether Yeon-su knew she'd been hypnotized. From the mood of it, she might remember that stretch, if only faintly.
"Haa...!! What do I dooo...!"
That was when it happened.
"Oppa, what's wrong?"
"Oh. Eun-ju."
Ha Eun-ju. Ha Yeon-su's little sister, and the youngest daughter of this house. The only time I ever got to see her was when her water bottle ran empty.
"Been a while."
"Yeah. Why. What's with the nostalgia."
Eun-ju asked without sparing me a single glance.
"Yeon-su and I..."
"Lovers' quarrel again."
"No! This time it's actually weird!"
"Weird? You and Unnie have been weird your whole lives."
"No...! Just listen to me...!"
"What."
"Never mind. I'm not telling."
How was I supposed to say I'd groped Yeon-su while she was hypnotized?
"Forgot what I'm like, did you?"
She set the cup down, rolled her wrists with a flick, and pressed her fingers until they popped.
"I don't hear anything."
"That's proof I'm healthy. Come on, what is it. Out with it."
"I couldn't tell you if it killed me."
"Then die, and tell me."
Eun-ju outdid Yeon-su in more ways than one. The hair dyed pink. The skin white as cloud. The narrow waist... The full breasts...
"Haa... why am I like this lately, seriously...!"
"I can tell just by looking..."
"Huh?"
"I can tell just by looking. It's because you're horny."
"?!"
"...Heh?"

Eun-ju laughed under her breath and sat down across from me.
"Okay, let's see... your sex drive is too... strong...!"
She scrunched her brow hard.
"Your sex drive was so strong you went and screwed up."
She'd shouted the right answer.
"Big sis here will fix it for you, so tell me the truth."
Eun-ju thumped her chest with a fist. Even in the middle of that, my eyes went to the way her breasts bounced. I thought it over for a long while. I even got as far as wondering whether, if this hypnosis app ever became known to the world, it might put the entire planet in danger.
"If you don't talk right now, I'm asking Unnie."
"Because of this app."
I hurriedly held up Please-Let-It-Work Hypnosis App for Eun-ju to see, and in two seconds flat the corners of her mouth climbed like they meant to split.
"You used that on Unnie, huh?"
