I Learned the Taste of A Kiss

““Nnnn…..!?””

In the dimly lit room,

Two figures were overlapping on the bed.

Yukine’s silver, lustrous hair shimmered in the moonlight, and her eyes, just beyond her nose, were faintly blurred with tears.

My lips and Yukine’s lips were touching.

A soft sensation I had never felt before, and warmth radiating from where we touched.

After a moment, I moved away from Yukine and sat on the bed.

“…………”

“…………”

Yukine also sat up, placing her hand on her lips.

“N-Nii-san.”

Yukine calls my name as if to confirm something.

“Y-Yukine…”

I can’t figure out what to say, so I could only respond with her name.

“W-We, um, we kissed, didn’t we…?”

“T-That was, um, more like an accident…”

“But, Nii-san, you touched my lips with yours, right?”

“Ugh!! W-Well, that’s…”

I knew. 

I knew that I accidentally kissed Yukine.

But as an older brother, I didn’t want to admit it.

“…Ehehe, looks like we finally did it, huh?”

Yukine murmured with a cheerful tone.

“This is, um…”

No matter how I tried to find the words, my pounding heartbeats were too loud, making it hard to think straight. 

And on top of that, I had been given an absurdly strong aphrodisiac by Yukine.

Honestly, my head was on the verge of short-circuiting.

“H-How was it, Nii-san? I mean… my lips?”

“Wh-Who asks for feedback right after a kiss?!”

“You admitted we kissed!”

“Ugh! Th-That’s…”

It’s no use. 

It’s clear as day that Yukine and I kissed. 

Yukine giggled happily.

“Hehe, Nii-san liked my first kiss… That makes me happy.”

Her genuine words made my heart skip a beat. 

Who wouldn’t be happy to hear something like that?

“N-Nii-san, was it your first time too?”

“W-Well, yeah! B-But, I mean! This was an accident! It wasn’t intentional, so it’s hard to call it a first kiss!”

I desperately resisted.

“So, Nii-san can think what he wants. But I’ll always remember it as kissing you, okay?”

“Y-You can think whatever you want.”

I couldn’t bring myself to face Yukine’s innocent delight, so I turned away.

“Hehe, I kissed Nii-san~♡“

“Don’t say it over and over again! It’s embarrassing!”

“Embarrassing? Why? We’ll do it more from now on, won’t we?”

“We won’t! This was the first and last time!”

I protested, and Yukine raised her voice.

“Impossible!! I want to kiss Nii-san more! But, this time it will be a French kiss, okay? That was just a childish peck!? There’s an evolved form of kissing you know!?” 

“Hell with evolution!! Also, Yukine is still a child!” 

“Hmph! I am not a child anymore! You looked at my body right!? It’s pre-pretty sexy don’t you think!?”

“Th-that I don’t know! Cause I haven’t seen it!”

“You! You’re being more of a child!” 

Yukine spoke in a tone like a primary school student telling off a teacher.

In this situation, I’m at a disadvantage in every aspect. 

Not only that, but my own condition isn’t great either.

As I contemplated a quick retreat, Yukine, growing impatient, hugged me tightly from behind.

“Ugh!!”

“Nii-san~ Let’s do it, okay~?”

“W-What are you talking about?”

“Do you like making girls say that? Does it excite you?”

“T-That’s not it!”

It seemed Snowin has noticed my weakness and is pressing on relentlessly.

“Nii-san~ Since we’ve already kissed, it won’t make a difference no matter what we do~ Right? ♡“

“This is enough for today! It’s late, so go to sleep!”

I pushed Yukiine away and forcibly got into bed. 

Naturally, Yukine followed suit and gets in too.

“Fine, then I’ll sleep here too!”

“Yukine, sleep in your own room!”

“B-But~! If we’ve come this far, we might as well go all the way, right?! And, like, Mom and Dad aren’t home today, you know?! We can make as much noise as we want, right?!”

“Don’t talk about making noise so casually!”

“We’re going to have an intense night, Nii-san~!”

“Please, spare me!”

Feeling sorry but determined to protect my chastity, I kicked Yukine out of the futon. 

Then I wrapped myself up tightly in the blankets, creating a fortress-like cocoon.

“Nii-san meanie!”

“Goodnight!”

“Muu…”

Yukine pouted discontentedly, puffing out her cheeks. 

As I maintained my fortress-like position, she eventually sighed in resignation.

“After all, I got to kiss you today, so it’s fine. We can continue next time, Nii-san♡”

“We’re ending it here, though!”

“fufu, goodnight, Nii-san!”

“Goodnight!”

Finally, Yukine left the room. Hearing the sound of the door closing, I finally breathed a sigh of relief.

“(i-it was really close this time… I mean, we actually kissed…)”

I touched my lips.

Whether it was my imagination or not, there was still a lingering sensation, and a warmth spread from deep within my body.

“(…Let’s do it one more time. Otherwise, tomorrow will be a nightmare.)”

With determination, I seriously considered installing a lock on the door to my room.

Returning to my room, I immediately dived into my bed.

Clutching my stuffed animal tightly, I started writhing in excitement.

“(I-I actually kissed Nii-san! We really kissed!)”

“Uuuuuuuuuuuuuu~~~~~~~~~~~!!!”

The excitement refused to die down.

I touched my lips again, recalling the sensation from that moment.

“(Kissing… it felt soooo good.)”

I kept replaying that moment with Nii-san in my mind over and over again.

Each time, I felt a warm sensation spreading in my lower abdomen.

“(…If we went further, I’d feel even more…)”

“AAhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!!!”

I want to do more with Nii-san…
