My body bounced around uncontrollably.
My pussy slipped out of my control, clenching tightly inside.
Her fingers moved obscenely, as if they were delicious food.
‘This is on a whole other level…’
I remembered the first day I possessed this body—when I tried something like masturbation.
Back then, it was just tiring and I barely felt anything, but now…
I thought I’d gotten used to it, but every place she touched sent new sensations through me.
Yena’s long fingers pressed against my vaginal walls, pushing in before scraping their way back out.
‘Just now—ah…!’
It was so intense I couldn’t even moan properly.
It felt deeper than anything I’d ever done to myself.
When I was alone, I could barely fit a single finger.
But Yena pushed hers in and out dangerously deep, painting me with her touch.
Like black ink dripping onto white fabric, I was stained in her colors.
‘Damn… I can’t go back now…’
Her fingers were long enough to reach every erogenous zone inside me.
Each scrape against my walls made me drip even more.
Her fingers coated my insides with lewd slickness before rubbing their way back in.
Is this what they call perfect sexual compatibility?
If I exaggerated a bit, I could practically visualize the shape of her fingerprints.
‘…Fingerprint-recognizing pussy.’
Disgusting thoughts flooded my mind.
My body trembled at how obscene this was—something that shouldn’t exist in this world.
I wondered what face Yena would make if I told her.
“Ah—hah…!”
Of course, that thought was soon drowned out in white.
Every time she curled her middle finger and scraped my walls, my pussy twitched and convulsed.
It stretched perfectly around her fingers.
I’d really… become a pussy custom-made for Yena.
‘A fingerprint-recognizing, tailor-made pussy…’
The situation with my lips wasn’t much better.
“Mmph, slurp, haah…”
If anything, it might’ve been worse.
Unlike fingers, her soft tongue slid in effortlessly.
No matter how much I sucked and nibbled, I couldn’t get enough.
Every movement sent shivers through me.
Each moment was a new thrill.
I didn’t know much, but Yena was insanely talented at kissing.
No—she had to be.
Otherwise, my pathetic reactions wouldn’t make sense.
I imagined Yena kissing someone else.
“Ngh, hup…! Mmph!”
I absentmindedly bit my tongue lightly.
I glanced at Yena’s expression, and sure enough, her index finger brushed against my pussy.
My eyes flew open, and I reflexively shook my head slightly.
I’m already at my limit.
If a third finger goes in, I’ll pass out for sure.
I was barely holding on, desperate to see Yena naked.
If I go past this point, I’ll faint.
My body has no strength left.
Whether she sensed my desperation or was just teasing, Yena withdrew her hand and kept going.
“Slurp, haah, ngh…”
The relief of escaping that situation soon turned into gunpowder, fueling the fireworks exploding in my head.
My body went slack, and my leg muscles went on strike.
The space between my pussy and the bed shrank.
“…!”
Which meant her fingers were sinking even deeper.
Not missing my reaction, Yena perfectly timed it—thrusting her fingers up hard enough to make a wet sound.
My legs jerked up as my muscles tensed.
My vaginal walls clenched around her fingers to the point of suffocation.
‘Is this some kind of rhythm game…?’
Yena frowned slightly.
When I relaxed a little, she smirked again.
Even that smirk looked beautiful—I was truly done for.
While one hand worked my pussy, the other supported my waist and back.
Her lips against mine even bore the weight of my head.
‘Her mouth and hands are ruthless…’
But sometimes, she was gentle.
Like a bratty kid teasing the girl she likes.
I could feel Yena’s affection in it.
Sweet pleasure burst where our lips met, and I came again—just a small one this time.
‘Ah, I was supposed to say something before…’
Did she notice?
No, probably not.
It was right after a big climax.
Besides, I didn’t even make it obvious.
“Ngh, tsk, chu…”
“Pwah, what? Tired?”
“Aah, nnh… Chuu—”
“Smack. Ugh, you’re so horny. My tongue hurts—let’s rest. You’re just lying there, so you wouldn’t know.”
Seems she really didn’t notice.
Mischief filled Yena’s eyes.
‘Tch, playing dumb…’
Staring into those eyes, I wondered if this was true happiness.
Yena slowly pulled her fingers out, as if signaling the end.
A little disappointing… but we have school tomorrow.
I squeezed my pussy, making my reluctance obvious.
Her fingers slowed their retreat.
“Right, if it’s tough, we should stop.”
“…Yeah.”
“But I still have a long way to go.”
“Ah—ah! If you say that—hah! Don’t scrape—!”
This girl… has no intention of stopping here.
The retreating fingers plunged back in deep.
Then, they curled and scratched relentlessly.
No matter how many times it happened, I never got used to that feeling—my body shook violently.
“And, heh. One more thing.”
“Ugh, ah, there, hng…!”
Yena’s gaze suddenly changed.
Sharp and ominous.
Somehow, I felt an incredibly uneasy premonition.
“You were supposed to tell me if you were going to leave.”
“Hng, ah! Mia! Hahk…!”
Goosebumps prickled around my neck.
I apologized immediately, but Yena was already in a frenzy.
Her fingers dug deeper, faster.
I owed her yet another favor on her shoulder.
I thought there was nothing left, but my pussy kept spitting out more, as if it didn’t know its limits.
“Try making an excuse, at least.”
“Y-yes, I was, using my mouth, so I couldn’t, haah…!”
For a hastily made excuse, it wasn’t bad.
‘I couldn’t talk because I was kissing you.’
A perfect truth.
I opened my mouth wide and bit her shoulder—ah!
Biting her shoulder tightly made it somewhat bearable.
The pleasure, which had felt like a 10-meter tsunami, now seemed like an 8-meter wave.
I think I understand why pregnant women grab their husbands’ hair.
“That’s your excuse? Hmph, fine. But you still need to be punished.”
“Hngk, ngh… Y-you’re being, selfi—ahh…!”
Punishment?
Just hearing the word made me shiver.
What, was she declaring the end of sex or something?
What could she possibly do?
Make me wear weird clothes?
Fuck me with three fingers?
Shove her tongue in my mouth and violate me?
‘…I could handle any of that, somehow.’
Things that would’ve made me tremble a few days ago didn’t seem so scary now.
Maybe because I’d done it before.
There was even a chance to turn the tables.
I was a little more familiar with it now.
‘Wait…’
Now that I thought about it, it was weird.
Why did I have to be punished?
No, even if I was punished, there was something I needed to do first.
I replayed the earlier situation in my head.
I definitely…
‘If you’re about to leave, say something.’
‘I-I’m about, to, lea—hyahk-!’
Let’s not dwell on what came after…
Anyway, I followed her words perfectly.
At the time, I didn’t think much of it, but now it seemed like I’d obeyed her command well, right?
“Then—”
“Pfft, y-you should, reward me first…!”
I cut her off mid-sentence, countering her at the perfect moment.
The fingers pistoning inside me stopped.
I used the pause to catch my breath and regain stamina.
When I pulled my mouth from her shoulder, a string of saliva stretched between us—it looked pretty lewd.
“Reward? Why should I?”
“B-because earlier… I said I was about to, leave, didn’t I…?”
The more I spoke, the more my confidence faded.
My voice grew smaller, pitiful.
Of course, my logic was flawless.
I really had listened and followed her order.
The problem was the girl staring daggers at me. I wished she’d just admit defeat.
“Aha.”
“…”
“I see.”
“…What?”
Yena didn’t say anything after that.
Her fingers stayed still inside me.
Confused, I met her eyes—she didn’t seem flustered.
It didn’t feel like she was stalling for time, either.
It was more like… her gaze said my fate was already decided.
After a few seconds of eye contact, I was the first to look away.
‘This is getting scary.’
Not because I was losing steam down there. No, that wasn’t it.
Yena looked like she was prepared to stay like this forever.
‘Sigh…’
Do I have to bend again?
She really never lets me win even once.
“…Yena.”
“Yeah. I’m listening.”
“Can’t we just… cancel out the reward and punishment? Call it even?”
Offset. Plus minus zero. Just wipe the slate clean.
I never liked the whole reward-punishment system anyway.
It feels like some medieval slave punishment.
Silence.
Yena didn’t say a word.
In the end, I was the one who gave in again.
“Fine, fine! Stop glaring at me like that!”
“No, I was just… thinking a little. Hehe.”
Yena put on an unconvincing act.
‘Oh, you love thinking so much, huh?’
She’d have kept it up until she got the answer she wanted.
“…Can I choose the reward?”
“Let’s hear it first.”
Her expression was relaxed.
‘This girl, seriously…’
Yena only ever did the most annoying things.
She could’ve just agreed.
Gritting my teeth, I made my proposal.
“Take off… your clothes.”
“…That’s it?”
Crack.
Something shattered in my head.
I tried to stay calm, but it wasn’t working.
Might as well go all in now.
“It’s not just that! While I was, cumming over and over, you didn’t even take off a single layer! D-do you know how embarrassing that is…?”
“…”
“I’ve been n-naked this whole time, heh…! But you—ah! Why won’t you keep your fingers still?! Ngh… You—! You just keep, hng…!”
Snort.
“Ugh, ah, hahk…!”
