Finger Insertion
I stared at the whiteboard, completely at a loss for words. Once again, the mission left me speechless. I rubbed my neck, scratched the back of my head, and roughly pushed my bangs aside, all while stealing glances at Seo Jian out of the corner of my eye.
She seemed just as shocked. Her eyes blinked rapidly, her mouth opening and closing like a fish gasping for air.
“……”
“……”
Then, suddenly—
“Agh!”
Bang!
Jian slammed her fist on the table. The loud noise made me flinch backward instinctively.
“Whoa, you scared me…”
She whipped her head up and glared at me.
“Hey, Kim Hanbin.”
“…Yeah.”
“Why don’t you explain out loud what that number eight on the board means?”
A few possibilities we’d brainstormed together just the other day flashed through my mind. One of them had been the mortifying “weekly masturbation count” that we’d torn up in embarrassment… I quickly tallied how many times I’d done it from last Wednesday’s lunch until today.
Exactly eight. Shit, this is awkward.
My ears burned red at the thought of Jian learning about my private habits. I averted my eyes and mumbled vaguely.
“Well, uh… that’s from last Wednesday until today…”
“Until today, what?”
“That… you know. The number of times I did it alone.”
Bang! She slammed the table again.
“Ha! So you’re saying you jerked off eight times in a single week?”
“Hey! Guys our age do it about once a day, don’t they? I’m not some kind of freak.”
…Probably, I added silently.
“Then why not stop at seven? Why eight?!”
Nobody would care, but my usual routine was right before bed. One quick session and I could fall asleep feeling refreshed. On mission days, though, it was different. I figured I should take care of it in the morning just in case. It was my own little preparation, a kind of consideration… Jian would probably call it ridiculous, but that pointless thoughtfulness had apparently made this mission even harder.
“…You horny bastard.”
“I’ve got nothing to say to that.”
“Of course you don’t. I’m at zero, after all. Uuuuugh!”
Jian banged her head against the table. If she kept doing that, she was going to turn into an idiot.
“If you’re gonna do it, at least spread it out over a few days. Eight times?! I haven’t done it once!”
“……”
“Yeah, I get it… but damn, I had a feeling this would happen. I kept quiet about telling you not to jerk off because it felt too weird, but—!”
Jian: 0 times. No matter how unfair or justified I felt, with me at eight and her at zero, I had no choice but to keep my mouth shut. Honestly, if I’d just held out this whole week, we could’ve cleared this mission for free. …The reverse was also possible, but I decided not to mention it.
“I’ll do whatever you want me to,” I said.
“You’re stating the obvious. If we don’t do this, we can’t get out. Ever. And did you forget what we agreed on in the contract? Anything that happens in the rest area stays in the rest area. What does that mean?”
“It means we shouldn’t read too much into the missions.”
“Exactly. You remember. So I won’t attach any meaning to whatever you do to me either. Here, take this.”
“……?”
Out of nowhere, Jian pulled something from her pocket and held it out. It had a plastic-like texture. It was—
“A condom?”
“J-just in case. We bought them last time and only used one. There were extras, so…”
“You want me to wear this?”
“Ugh, seriously! Do you have to ask about every single thing?”
After snapping at me, Jian perched herself on the edge of the table. She turned her head slightly to the side and shifted her legs, opening them just a little, then not quite.
Gulp.
I swallowed hard. Jian had shown her resolve first. In that case, the right thing to do was to follow along without complaint or overthinking.
I was about to yank down my tracksuit pants when Jian shouted.
“Wait, why are you suddenly taking your pants off?!”
“You told me to put on the condom.”
“Are you insane? Why would I do that with you? Put it on your finger! Your finger!”
“…Oh. That’s what you meant.”
I awkwardly pulled my half-lowered pants back up.
===
Seo Jian, age twenty (technically). Her birthday was in January, so she had already turned twenty. Right now, she stood at a pivotal moment in her life.
Ever since transforming into this body, she had never once masturbated. She had touched herself out of curiosity once, but the overwhelming shame had stopped her from ever doing it properly. An untouched, inexperienced body. And now she was pulling down both her pants and panties in front of Kim Hanbin once again.
When she slid her pants down, she kept her feet planted on the floor, lifted her hips, and yanked them off in one go, all the way past her knees. As she sat back on the table and swung her legs around, the tracksuit pants naturally slipped to the floor. Her panties had gotten tangled with them and came off together.
Jian pressed her thighs tightly together and curled into herself. Sitting on the table made the position awkward, but people always found strength in a crisis.
“……”
“Are you undressed?”
“…Yeah.”
In front of her stood Kim Hanbin, wearing a blindfold.
“…Should I start?”
“Stop asking about every little thing.”
“……”
Rip. Hanbin tore open the condom wrapper and slipped a finger inside the rubber. Jian watched quietly for a moment before urgently grabbing his wrist.
“Hey, why two fingers? Use just one.”
“Ah, right. Sorry, it was automatic.”
“…I’ve never done this before. So be gentle. Really gentle. I won’t say anything, okay? We both know the deal, right?”
“I know.”
We were just friends, after all. Friends didn’t do things like this. Hanbin wanted to say it, but he swallowed the words that had risen in his throat. With this awkward mindset, even if someone spoon-fed him the opportunity, he couldn’t bring himself to act recklessly. It was the kind of relationship where you had to be careful even though you were close.
“Can I ask one more thing?” Hanbin said, placing a hand on Jian’s knee.
Even though she looked reluctant, Jian slowly lowered her legs and parted her tightly pressed thighs. Even if the person in front of her couldn’t see, the fact that she was exposing her most private area made her face burn hot and her mind go completely blank.
“W-what is it…?”
“I don’t really know how to touch you. I’ve never done this either, so I’m not sure how girls usually like it…”
“……”
Jian was in the same boat. Of course, she had seen it in porn. There didn’t seem to be anything too complicated about inserting a finger and moving it around. But could you really just copy what they did in porn? It looked like Hanbin had gotten stuck here.
Can I even handle this?
That’s when Jian thought about it. The whiteboard demanded a full eight orgasms. As someone who had never once reached climax since becoming a girl, she had no idea how difficult or time-consuming this mission would be. Guys just had to ejaculate, but…
What does an orgasm even feel like for a girl?
She had seen it in porn before—women trembling, fluids gushing from their pussies as they moaned and cried out. When she imagined herself in that position…
No way! No way! No way!
But on the other hand, the rewards were solid. 1.5 million won was a lot of money, and Lee Hyunju T’s six-month special lecture was something she had looked up just days ago because she wanted to take it. Plus, something good was supposed to happen for Kim Hanbin’s family.
Contract clause 2: Both parties must do their absolute best to complete the missions.
It was something Jian herself had written. So she squeezed her eyes shut and spoke.
“J-just… put it in a little.”
“Got it.”
Since he couldn’t see, Hanbin’s hand started at her knee and slowly worked its way up her thigh, feeling around as it went. When it reached her groin, he pressed firmly around her sex. It wasn’t intentional, but it felt like he was deliberately teasing the area.
“…W-what are you doing?”
“I can’t see, so…”
“……”
Then his finger lightly brushed against her clitoris. The sensitive spot made her shoulders tremble involuntarily. While her mind went completely white, Hanbin’s hand finally touched her pussy.
Fuck, fuck, fuck…!
What the hell is this?
Both of them clamped their mouths shut and stayed perfectly still. The condom-covered finger traced around her entrance, as if searching for the right spot. It was a bit timid, just light prodding touches. His intention was full of care and caution, but—
“Eek! W-what are you doing?!”
“…Huh?”
“N-not there…”
Jian grabbed Hanbin’s hand. No wonder she was startled—his finger had touched her asshole instead of her pussy. She had tried to stay quiet and keep her mouth shut, but in the end she had to step in herself. She took his hand and guided his finger right to the entrance of her slit.
“Here. Put it in here.”
“……”
“S-slowly.”
“Okay.”
One knuckle of his index finger, then another, slid into her pussy. Just two knuckles. That was all it took.
Jian gripped the table with her left hand and covered her mouth with her right, unable to look away from what was happening between her legs. Hanbin’s finger was inside her.
And the sensation was—
“It f-feels weird…”
A strange sense of intrusion. And a subtle, creeping pain.
“I’m going to move now.”
“…Hup!”
Just two knuckles sliding in and out. The speed was agonizingly slow. The tip of his finger would peek out, then disappear back inside her again and again. Jian watched the entire process without missing a single moment. Even if she tried to pretend she didn’t notice, she couldn’t ignore the changes happening to her own body.
The already slick condom was becoming even wetter, glistening.
“Hngh…”
“You okay?”
“Y-yeah… j-just keep going… and don’t say anything…”
To anyone watching, the two of them would look like they were working incredibly hard to complete the mission. Unfortunately, the mission hadn’t even properly begun yet.
Current Record: Kim Hanbin - 8, Seo Jian - 0
Jian still had to reach climax a full eight times.
