Chapter 5: Christmas Eve

Christmas Eve

“Onii-chaaan!!!”

As soon as the intercom rang—before I could even get to the door—my little sister Mutsuki threw it open and leapt into Kouta-kun’s arms.

We were having a Christmas party at home today, so we’d invited Kouta-kun over.

Still, Mutsuki really had no sense of restraint when it came to my boyfriend.

It wasn’t just once or twice that her attitude had sparked a fight between us sisters.

“M-Mutsuki-chan…”

“Ehehe. Welcome, Onii-chan! Make yourself at home, okay?”

“Hey, Mutsuki! Kouta-kun is my boyfriend—don’t cling to him like that!”

“Ugh, you’re such a grump, Onee-chan. What’s the big deal?”

“That’s enough! Go back to your room already!”

“Onii-chan… Onee-chan said something mean to me…”

With teary eyes, Mutsuki turned and pleaded to my Kouta-kun.

Ahh, and he’s too kind for his own good—now he looks all troubled.

I forcibly peeled Mutsuki off him, and she let out a spoiled little whine, “Aaahn~”

“Good grief… Sorry, Kouta-kun. I made a cake for today, so look forward to it, okay?”

“For real!? A cake made by Yayoi? That sounds amazing!”

“Geez… You’re such an exaggerator, Kouta-kun.”

“That’s not fair, Onee-chan! I helped make it too, you know!”

“Really? Then I’ll look forward to it even more.”

“Yup! I worked really hard, so be sure to tell me what you think after you eat it, okay?”

“Ahaha, you got it.”

Ugh, Kouta-kun is way too soft on Mutsuki!

He’s my Kouta-kun! Mutsuki seriously needs to learn what restraint means!

Just as I was fuming, Kouta-kun placed a hand on my head and gently whispered by my ear, “Sorry. Once we’re in your room, let’s spend some time—just the two of us.” That alone made my heart melt. I’m so hopeless.

Once we were alone in my room, I let out all the stress Mutsuki had caused by doting on Kouta-kun as much as I could.

I hugged him tight, rubbed my cheek against his chest, and showered him with kisses on the cheek—chu chu chu.

And then, while I was doing all that, Kouta-kun suddenly cupped my chin and kissed me hard on the lips.

H-h-h-h-h-huhhh!?

A kiss that cool and unexpected—how am I supposed to think about anything but Kouta-kun now!?

Just as my mind went completely blank, something soft slipped into my mouth.

Huh?

What was that?

What just went in…?

As I panicked, that soft something began to ravage the inside of my mouth.

Ahh… This sensation… actually feels really good…

My head turned all fuzzy, and I couldn’t think anymore—but without even realizing it, I started moving my tongue to tangle with that soft something.

What is this?

It feels way too good…

“Nn… fuu… chu… chupu… fwaa…”

I couldn’t believe those kinds of indecent sounds were coming out of my own mouth…

I was embarrassed, but even more than that, I was getting completely lost in this pleasure I’d never felt before.

But… I can’t.

If this keeps going, I’ll lose control…

“Chu… nn… W-wait, Kouta-kun… ahn…”

When I asked him to stop, Kouta-kun pulled away.

With the feeling of our entwined tongues gone, I unconsciously reached out with my own, wanting more.

“Did it feel good?”

“Y-Yeah. That was my first time… and it made my head go all fuzzy.”

“Same here. I’ve never gotten that turned on before.”

“—You want to do it, right, Kouta-kun? We can’t today since my parents are home… but tomorrow, no one’s going to be here around noon. Will you come over again?”

Tomorrow, my mom and dad would be working, and Mutsuki was going to a Christmas party at a friend’s place—so no one would be home.

“Huh? Are you sure?”

“Yeah. I’ve been thinking… I want to move forward, too…”

“Seriously? That makes me so happy. I love you, Yayoi!”

“Hehe. I love you too, Kouta-kun.”

Then, after another kiss just as intense as the last, we went down to the living room and enjoyed the Christmas party with everyone.

Mutsuki teased, “Onee-chan, your face is kinda red. So suspicious~” but I forced a smile and said, “I’m just excited, that’s all!”

Kouta-kun laughed, “Ahaha,” looking like he was having a blast. Just thinking about what we’d do tomorrow made my cheeks flush even redder than before.

“Here. This is your Christmas present.”

Kouta-kun had brought gifts for everyone.

He even had something for my dad, who wasn’t there.

My mom looked flustered, saying, “Oh my, I’m so sorry. I didn’t get anything for you, Kouta-kun,” while Mutsuki was completely ecstatic over her gift.

I pouted a bit, not loving that I’d been grouped in with everyone else—but then he said, “I’ve got a separate one just for you, Yayoi,” and just like that, I was flying high again.

Maybe Kouta-kun really does have me all figured out.

That’s just how good he is at making me happy.

After the party ended and we went back to my room, he pulled something out of his bag and handed it to me. “Here—it’s your present.”

I asked, “Can I open it?” and when he nodded, I carefully unwrapped it, making sure not to tear the paper.

Inside was a small box.

I opened the lid, and inside was a beautiful necklace.

“Wow… It’s so pretty. Thank you, Kouta-kun. But… how’d you buy it? Wasn’t it expensive?”

I was thrilled, but also worried—this didn’t seem like something a middle schooler could afford.

“Nah, it wasn’t that pricey. I don’t really spend my New Year’s money, so I’ve got a decent amount saved up.”

Kouta-kun explained cheerfully, clearly happy that I liked it.

Touched by how thoughtful he was, I hugged him tight, rubbing my face against his chest. “I love you. I really do, Kouta-kun.”

He stroked my cheek and whispered back, “I love you too.”
