The Sincerity of a Kiss

“Why?! ”

The failure message caught me off guard too, but the one truly panicking had to be Seunghee herself. She had swallowed her shame, spread her pussy for me, and even received a kiss there. To still get a failure after all that? If this had been a soccer match, no one would have batted an eye if she grabbed the referee by the collar and shook him.

“Sorry. Was I too gentle?”

“No you weren’t?! You weren’t gentle at all?!”

Seunghee’s frantic reaction was strangely entertaining. For me, it was simple—I could just try again. But for her, it must have been devastating. She had worked up so much courage for that single act. When my lips touched her, I felt her entire body tremble violently against me. If she hadn’t felt it properly, she wouldn’t have reacted that way. Yet the system’s judgment was clear: failure. The only explanation I could think of was that I had been too soft.

Seunghee’s face flushed crimson as she made a despairing, tearful expression.

“I’ll try again, Seunghee.”

“Euu~!”

Seunghee stomped her feet against the mattress. No matter how much she fussed, the task remained the same. The system’s judgment was absolute. There was no referee here to grab by the collar.

After stalling for a long time, Seunghee finally resigned herself when the system prompted her again.

“This time… please make it work.”

“I’ll do my best.”

“Hic…”

Standing once more, Seunghee spread her pussy for me. The pose was obscenely lewd for a girl who, until yesterday, had been little more than a stranger to me. I decided to push her further.

“Can you push your hips out a little more?”

“Euuuuuu~~!!”

To be honest, part of me was enjoying her reactions. Her embarrassed squirming was genuinely fun to watch. But there was also a practical reason—I didn’t want to fail again. If I failed, we’d have to repeat the whole thing. Better to finish it properly in one go.

Seunghee squeezed her eyes shut and thrust her hips forward even more.

“Spread it a bit wider. We can’t afford to fail again.”

“Ahk…”

Seunghee pulled her pussy open as wide as she could. She had probably never spread herself this obscenely in her entire life—especially not in front of a man. I told myself it was like a vaccine for the even more intense acts that would come later, but even then, this felt excessively harsh.

“This time I’m going to do it harder.”

After she had gone this far, I couldn’t allow another failure. I needed to end it decisively. I took careful aim at her swollen, protruding clit and brought my lips to it once more.

“──Ah!”

I felt the firm little bump slip between my lips. I took that tiny bud fully into my mouth and sucked on it with an audible chu sound.

-Chup.

“Ahhyang──!!”

The strong kiss made Seunghee leap as if she might faint. It must have been overwhelming for a beginner. It would have felt far more intense than the first kiss. But this time I was certain. There was no way this would fail.

However…

“Why??!!”

Seunghee let out a scream. …Seriously, why? I had been one hundred percent sure it would succeed this time.

“Whywhywhywhywhy? Whyyyyy?!”

Seunghee hopped in place. Meanwhile I stood with my arms crossed, deep in thought.

“I don’t want to! No no no no no~~!!”

The hopping Seunghee eventually rolled around on the mattress, chanting “I don’t want to.” I watched her spinning ass and exposed pussy in turns while pondering the cause of yet another failure.

It probably wasn’t the intensity. When Seunghee had kissed my glans, she had done it much more softly and still passed on the first try. So was the location wrong? Was “clitoris” in the phrase “kiss the clitoris” not literal, but some kind of metaphor?

Pussy bean. Clit. No other body part came to mind. No matter how hard I thought, it had to be the clitoris.

“…Seunghee. Let’s try one more time.”

“I don’t want to! That’s enough! I’m not doing it!”

Seunghee sprang up in protest. I let out a deep sigh.

“You’re not going to save Seungpil?”

“Euu! That’s so cheap!”

“Who’s calling who cheap? Do you think I’m doing this because I enjoy it?”

“Ugh…”

It wasn’t exactly enjoyable, but it wasn’t like I was forcing myself through something I hated either. Still, there was no need to tell her that.

“You might be embarrassed, but I’m not doing this because I want to. There’s simply no other way.”

“Euu…”

“Seunghee. I know it’s hard, but let’s keep trying a little longer. Since we don’t know the cause, we have to keep experimenting until we figure it out.”

“Euu…”

“This time I’ll be gentler. Since doing it harder on purpose didn’t work, the problem must be something other than intensity.”

Seunghee hung her head at my words.

“…Fine.”

Stalling wouldn’t produce any brilliant new ideas. In the end, she had no choice but to nod. She seemed heavily stressed, so I decided to be a little kinder.

“Good. This time, why don’t you sit on the floor? I’ll spread it myself.”

Of course, only my tone was kind. Even I had to admit the content was ridiculous.

“Euu… okay…”

With a tearful face, Seunghee obediently sat down.

“I’m going to spread your legs.”

“Euu…!”

I positioned her legs in a wide M-shape so her pussy was fully exposed. Seunghee covered her flushed face with both hands and turned her head away.

“Don’t you have any ideas, Seunghee? Any clue why it’s not working?”

“I don’t know!”

“Then we’ll just have to keep trying blindly.”

Her white labia were flushed deep pink from being forced open. The sight was both pitiful and strangely arousing. I didn’t think I had any sadistic tendencies, yet here I was. Just like she had done to me earlier, I spread her pussy open with my fingers. The flesh that met my fingertips was incredibly soft, like melting snow. To think such delicate skin existed. I found myself being extra careful, afraid I might hurt her if I pressed too hard.

“Then… here I go.”

“…Please just finish it quickly…”

I had already memorized the shape and structure of Seunghee’s pussy. For the third time, I pressed my lips to her now-familiar clit.

-Chut.

“Ahh…”

A little softer than before—about the same intensity as the very first kiss. And the result?

“Aah~.”

Seunghee let out a deflated groan, then flopped onto the mattress in utter resignation.

“Seunghee. Look at me.”

“Aah~ Why~.”

“Just for a second.”

“I don’t want to anymore~.”

I grabbed her hand as she tried to stay lying down and forced her to sit up.

“I’ve been thinking. This mission was described as ‘a kiss of ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠oath to fulfill one’s duties as a partner,’ right?”

“I guess…”

Seunghee listened with a gloomy expression.

“I think what’s been missing is that ‘sincerity’ part.”

“Even if you say that… how am I supposed to do more than this…”

“Stop hating it so much and try to accept it mentally. Since we’re doing it anyway, let’s at least try to enjoy it together.”

“Euu…”

“I know it’s not as easy as it sounds. I’ll do my best to make it feel good for you, Seunghee, so at least decide in your heart to accept it positively.”

“Euu…………Okay…”

Seunghee finally gave a small nod. I had a feeling that if this attempt failed too, she would really give up. That would be unavoidable, but since we had already decided to go through with it, quitting against her own will didn’t sit right with me. Besides, we still needed to save Seungpil.

Seunghee lay back on the mattress with her legs spread, as if entrusting everything to me. The same Han Seunghee who had been embarrassed just wearing a swimsuit a few hours ago had already fallen far enough to expose her pussy to a man. In terms of “vaccination,” the effect was undeniably effective.

I positioned her legs in an M-shape again and spread her open. Staring at her clit, I organized my thoughts.

An oath of sincerity. Kissing the partner’s clitoris. Was there some deeper meaning I was missing?

Had my sincerity been insufficient? Should I keep kissing until she actually climaxed? It wasn’t entirely impossible. This world was a little twisted in that direction after all.

At this point it was do or die. Normal kissing would obviously fail again. I decided to try every lewd idea that came to ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠mind.

Having made up my mind, I brought my tongue to her clit instead of my lips. I gave the protruding little bud a slow, wet lick.

“──Haang?!”

Caught completely off guard, Seunghee screamed and shot upright.

“Wh-what are you doing? What is this?!”

“I thought maybe my sincerity was lacking.”

“What does licking have to do with sincerity?!”

Seunghee kept babbling, but instead of answering I buried my face completely between her legs.

“Hyat! Wait! ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Just wait a second!”

Lick. Lick.

I focused on her clit.

“Hii─?!”

The mission only specified the clitoris. There was no need to lick anywhere else. I concentrated solely on that small pearl, determined to make her climax from it.

“Hi! Ah! Ah! Wait! Ah!?”

Every time my tongue brushed across it, Seunghee’s thighs clenched and opened, her hips jerked forward and back. Her whole body writhed like a snake dancing.

“Ah! Hey! Hi! Excuse me! Really! Wait! Ah! Ahh?!”

She had probably never been pleasured like this before. Her panicked voice rained down from above me. But I didn’t stop. I kept licking her clit without pause—flicking it like a snake, lapping at it like a dog, even pressing down hard and sweeping across it like a broom.

“Hii?! Hiiing?!”

Seunghee moaned and fussed with every stroke. Her exaggerated reactions must have come from the same genes as Seungpil. What an entertaining pair of siblings.

As I worked my tongue diligently, a sudden realization struck me like lightning.

I was licking her clit, but technically I wasn’t licking the clit itself. I was only licking the hood covering it. Just like a man’s glans, a woman’s clitoris is protected by a foreskin. And unlike a man’s, a woman’s clitoral hood doesn’t retract naturally.

Come to think of it, Seunghee had kissed my exposed glans directly. My erection had pulled the skin back automatically. But I had been kissing Seunghee’s clitoral hood, not the pearl hidden beneath it. That was the clear difference.

“Huuu, huuuung…!”

I glanced up at Seunghee. She was completely lost in the pleasure now, unable to think straight from the unfamiliar sensations. I gently pressed the sides of her clit and pulled the hood back.

The tiny pearl that had been hiding inside finally revealed itself. It was the smallest clitoris I had ever seen—normally completely buried beneath the plump ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠hood, cut off from the outside world. That was why all my previous kisses had failed. My lips had never been able to reach the actual clit because it was too small and stayed hidden.

Now that I understood the cause, there was no reason to hesitate. I kissed the fully exposed clit directly.

-Chut.

“───???!?!!”

It was barely a touch—my lips met it and pulled away. Yet Seunghee’s reaction was the strongest yet. Her wiggling hips froze solid. She couldn’t even make a sound. The stimulation had apparently overloaded her body.

Finally, the long-awaited notification rang out.

Aah. So that was it. The puzzle was solved at last.

At long last, we had succeeded.
