Becoming Her First Love

During dinner, Sieun's explanation continued. She began by saying that a sweet first love had come to her back in middle school. The way she gushed about falling for him at first sight like it was destiny, acting like an excited schoolgirl despite being twenty-five, was cuter than I expected. But honestly, I couldn't give less of a fuck about her first love. Still, I listened quietly.

She had been in her third year of middle school at the time, and the guy was a first-year. They were in the same fitness club, things got flirty, and she confessed first after reading the mood—only to get shot down hard. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Originally a pure-hearted romantic, Sieun said she turned into a total bitch after her innocence got trampled. I found it hard to believe that one rejection could flip a pure girl into a slutty dark version of herself, but that wasn't the important part.

After finishing her story, she made a ridiculous request of me.

“But that first love looks a lot like you. The face, the vibe—it's all similar. Your body's way better, though. He's basically a skinny twig. Super frail and delicate.”

“...”

“Don't hate me too much, Minjun! This is a secret, but he's a famous idol now. You could probably figure it out with a quick search, so I won't say his name.”

“...Why are you telling me this now?”

“Ahem. Minjun. You said earlier you'd grant my request without question, right?”

“Noona… you can't be serious?”

As the saying goes, assumptions get people killed, and Sieun's request didn't stray an inch from what I feared. That made it even more shocking. Cha Sieun wanted me to roleplay as her first love. And not just anywhere—in bed.

If the app was calling it a powerful reward, it had to be something truly insane.

My heart pounded harder after checking the quest. The app didn't usually hype things up unless the reward was exceptional.

“You came out wearing nothing but a robe, yet it looks like our Minjun would rather stare at his phone than at noona?”

At Sieun's voice, I snapped my head up and looked at her standing before me.

Fuck…

My heart, already heated from the sudden quest, slammed against my ribs like it wanted to explode. Her long, curvaceous body was sensual enough on its own, but the loosely tied robe offered teasing glimpses of skin that made it even harder to resist.

Unable to contain my excitement, a comment slipped out.

“Fuck… you're insane.”

“Why? Turned on?”

“Extremely, noona.”

She giggled at my answer, sat beside me, and whispered into my ear.

“So… will you grant noona's request? If you do, I'll make it really, really good for you~”

“...”

My ears itched like crazy, but I ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠fought with everything I had to keep my expression from collapsing. I planned to go along with it because of the quest, but requests were something you were supposed to resist first so the other person appreciated it more when you finally agreed.

I turned my head until our noses nearly touched and met her eyes. Maybe because my face looked dark, she wore an anxious expression. Seeing her go this far, it was obvious she desperately wanted to fuck that first love no matter what. The fact that she'd asked for first-love roleplay but immediately demanded bedroom time instead of a date made her claim of originally being a pure girl completely unbelievable.

Pure girl my ass. She was definitely a bitch from the start.

But as long as she tasted good, none of that mattered. Plus, with a satisfaction quest attached, this first-love possession sex had to be careful, deliberate, and utterly fantastic.

To build her anticipation, I steadied my breathing and spoke.

“Sigh… just for today, okay?”

“Wow!!! Thank you, Minjun. No—Seonho!”

Unable to contain her joy, she pulled me into a tight hug. Her erotic body, perfectly optimized to arouse men, pressed flush against mine. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠The sensation of her firm, textured muscles and elastic breasts squishing pleasantly against me was pure bliss.

“But his name is Seonho?”

“Ah, I wasn't supposed to say it. You can't post this online, okay?”

“We didn't even date. It was just a fling that ended, right?”

“Exactly. It's embarrassing that I got rejected.”

I nodded. Less out of agreement and more to steal a glance at the dizzying cleavage visible through her robe. Soon enough I'd see her fully nude, but there was an enormous difference between openly staring at nudity and stealing secret looks like this.

“Noona, since I'm properly granting your request, tell me about Seonho's personality and the scenario setup. You must have all sorts of fantasies you've imagined, right?”

“Wow, really?”

“Yes. I'll service you thoroughly.”

Her eyes grew misty with emotion at my words. It was only an act to clear the quest, but seeing her genuinely moved made my chest sting.

Well, since it's come to this… if it's good for the sister and good for the brother-in-law, everyone wins.

Justifying it to myself, I listened carefully as she explained her first love named Seonho and the sexual fantasies she'd built around him. The character I had to portray wasn't too difficult. Seonho was a classic prickly, frail pretty-boy type. He'd joined the fitness club because his body was too weak and he wanted to build at least a little muscle. It was slightly shocking that Sieun—with her voluptuous, stacked figure—had a taste for frail pretty boys who were her complete opposite.

That part was manageable, but the scenario she described afterward was far harder than I'd expected. It felt more like a thriller scene than erotica. Maybe it was the sinister, almost criminal look on her face as she revealed her fantasy that made it feel that way.

“Since the rejection can't be undone, we'll start from the aftermath. The heartbroken me kidnaps and confines the first love.”

“...Is this the kind of thing you've been imagining all this time?”

“Yeah. It's so fucking frustrating. Just because he has a decent face, he rejects my once-in-a-lifetime confession… But I never actually did it, so it's fine.”

I nodded while listening. No, I had no choice but to nod. If I teased her about being a potential sex criminal, it felt like I'd end up actually kidnapped and confined instead of just roleplaying.

At this point I was convinced something was wrong, but I had to clear the quest, so I pulled myself together. This place was hell right now.

“Anyway, assuming he's been kidnapped and confined, I want him to resist fiercely at first—really fiercely—then gradually have his mind broken by the technique that sends his whole body to paradise until he falls into corruption.”

“...The level is a bit high, don't you think?”

“So I'm counting on you, Actor Kim.”

She tapped my shoulder like a veteran director asking an actor for a good performance, then suddenly stood from the bed. She strode over, rummaged through her handbag, and pulled out handcuffs. Handcuffs. Before I could even ask why the hell there were handcuffs in her handbag, she approached me.

I couldn't stop my body from trembling like a deer standing before a lion.

“Noona… are you serious?”

“Yeah. Don't worry. I've done this plenty with my sex partners.”

Fuck, what exactly have you done plenty of? I was about to ask when she grabbed my wrist with surprising strength and dragged me to the head of the bed. She hooked the handcuffs to the metal frame above the headboard, stripped the robe off me in the blink of an eye, and locked both my wrists in place.

What I'd thought was one pair turned out to be two, so both wrists were firmly bound. The frustration doubled.

Click. Click.

I instinctively strained against the cuffs, but it was useless. They were solid. The smile on noona's face as she looked down at me was utterly sinister.

“I was originally going to use leather cuffs, but that lacks realism, so I went with metal.”

I was so stunned I couldn't speak. She gazed at my dumbfounded face with satisfaction, then shed her own robe and mounted my abdomen.

Sieun's nude body was far more incredible than I'd imagined. She had sharply defined eleven-pack abs, firm spindle-shaped breasts, and hips that looked like they could easily handle triplets. It was completely unrealistic—a body trained to the extreme solely to devour men.

Normally the sight alone would have made my eyes pop out. I could even feel the firm sensation of her hips and thighs pressing against my stomach, yet I couldn't get aroused. Fear and tension far greater than arousal swallowed me whole.

With my arms securely bound, she immersed herself instantly like an actor the moment the director called action. The thing reflected in her sinister eyes—eyes like a sex offender with ten prior convictions—was no longer Kim Minjun. It was the first love she'd been dying to fuck for the past ten years.

“Have you woken up…?”

Her chilling line was the signal flare. A splendid and cruel flare announcing the start of a bizarre kidnapping play that crossed far beyond the lines of ethics and common sense.

“S-Senior?”

Calling her senior had been prearranged, but the stuttering was one hundred percent real. There was no need to adjust my emotions—my voice trembled on its own.

Out of nowhere, I wondered if Yeonju lived with this kind of feeling every day. If so, that was too pitiful. I'd have to treat Yeonju really well from now on.

“Don't tremble so much. I brought you here to do something good for you.”

Sieun gently brushed my hair back. My pupils shook at the creepy touch and voice. But a weak line was NG. The first love I had to portray was said to have a prickly, bold personality—gentle most of the time but clearly vocal about things he disliked.

After all, the fact that he'd rejected Sieun, who was already a muscle monster back then, when he himself was even frailer than me, proved the guy had tremendous guts. So until his mind broke, I needed to resist at a fairly intense level.

I pretended to assess the situation by darting my eyes around before looking at the woman on top of me.

“...Are you crazy, senior? You know this is a crime, right?”

I spoke as if I were confident, but my eyes and lips trembled slightly. It wasn't intentional; I'd simply immersed myself in the situation following her lead. I hadn't realized it until now, but it seemed I had a real talent for acting. It was a huge shame that this talent had surfaced at a time like this, but I continued to stay in character. Quest or not, it was honestly starting to get fun.

“Who knows? If a guy claims he was raped by a woman… do you think people would believe him?”

As she spoke, the hand that had been stroking my hair moved downward. She straightened her index finger and drew slow circles around my areola.

“Just enjoy it… You can't escape anyway. If you resist too much, it'll only be hard on you.”

“You crazy bitch… ugh!”

Disliking the profanity, she raised her index and thumb nails and pinched my nipple hard. The intense stimulation—whether pain or pleasure, I couldn't tell—made me reflexively twist my body, but with her mounting me and both hands cuffed, it accomplished nothing. The cold metallic clinking from my wrists was the only thing reminding me of my current situation.

“Kh… even if you do this… do you think I'll like you, senior?”

“Who knows~? But it seems your nipples like it. They've already gotten this hard.”

Snap—.

She flicked my ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠nipple with her slender, long finger.

“Urgh!!”

A stifled moan burst from my mouth at the electrifying sensation. I tried to hold it back but couldn't.

“Ungh!… Fuck… take it easy, you crazy bitch.”

“Don't bark so loudly. It makes me want to torment you even more…”

She whispered stickily like a real rapist, then shifted her position, lying diagonally across my body.
