Chapter 425

“Why is Miyuki in such a hurry?”

Midori asked as soon as we entered the house, watching Miyuki clutch a large shopping bag to her chest and hurry up the stairs.

I answered, finding her retreating figure incredibly cute as she fled to keep anyone from discovering that the bag held my clothes.

"I think she might need to use the restroom."

"That must be it. I'm making breakfast as usual tomorrow morning, is that alright with you?"

"Of course."

"There's some fruit on the dining table. Take it up with you."

"Thank you, I'd love some. Thanks for having me over."

"Don't be silly. You're welcome to sleep over anytime."

Midori and Wataru knew that I had no parents.

Was that why she was being so accommodating? I might have earned a little sympathy, or maybe not.

'Since you're letting me stay the night, couldn't you give me your body, too?'

Swallowing those words, I offered Midori a warm smile and headed up the stairs.

I was on my way to Miyuki's room when I ran into Kanna.

"Hello, Kanna."

"You already said hello earlier. Again?"

"It would be awkward to just walk past without saying anything."

"You could say something else."

"Like what?"

"I don't know. You're sleeping over here?"

"It turned out that way."

"Are you sleeping in the guest room?"

"No. You guys use that for storage."

"In Miyuki's room, then?"

A sly gleam entered Kanna's eyes.

Seeing her expression, which shone with intense curiosity about a very specific thing, I nodded.

"Yes."

"Are you really just going to sleep?"

"What do you mean by that?"

"You know exactly what I mean."

'She sure seems interested in that kind of thing, huh?'

'In that case, you should drop by Miyuki's room around dawn.'

"Do you usually have deep conversations with Miyuki?"

"Of course."

'Then she already knows exactly what I'm going to do.'

'And yet she still asked if we were just going to sleep, teasing me...'

'Making me uncomfortable like this is definitely a ten-point demerit.'

'Which means the penalty—a threesome with the sisters—has just become mandatory.'

"Is that so? Good to know."

"Why do you ask?"

"Just because."

"You have a mischievous side, huh?"

"Just like you, right?"

"Like me?"

"Yeah. You're always imitating Miyuki's voice to tease me."

"Come on... that's not teasing, it's just my daily routine."

'She has an unexpectedly shameless side.'

'Given her talent for stubborn denial, she'd probably get along perfectly with Hiyori.'

"I'll take your word for it."

"The soundproofing in that room is pretty good, but really loud noises will still slip through."

"Why are you suddenly bringing up soundproofing?"

"Just something to keep in mind."

'So she already knew everything. Being incredibly close sisters, they must have talked about every little detail.'

'In that case, it's only right to let her hear plenty of moaning tonight to stoke her desires.'

After chatting with Kanna a bit longer, I slipped into Miyuki's room. She had already changed into thin pajamas and was neatly making the bed.

I walked up to her and asked.

"What about the clothes?"

"I tucked them away neatly in the closet."

"Already?"

"Yeah. I'll go grab an extra pillow."

"What extra pillow? The bed will be too cramped."

"Then what should we do?"

"We'll just have to hold each other to sleep."

Miyuki's face flushed slightly at my nonchalant remark.

Neither agreeing nor disagreeing, she focused on smoothing out the bedsheets.

She seemed nervous. It was a monumental occasion, after all—having me sleep over in her own house with her parents and sister right there.

"What do you want to do? Are you going to sleep right away?"

Miyuki asked, having finished neatly arranging the blanket.

I let out a chuckle and answered with a question of my own.

"If we were going to sleep right away, why did you arrange the blanket like that?"

"Just..."

"I'm joking. You aren't sleepy yet, right?"

"Yeah."

"Let's lie down anyway. After we finish this fruit, of course."

"Eating again?"

"Your mom gave it to us, so we have to eat it."

"But I already brushed my teeth."

"You can just brush them again."

I speared a nicely cut piece of melon with a fork and held it out to her. Miyuki parted her soft, scarlet-tinted lips.

I slipped the slice into her mouth and brought up the conversation we hadn't finished earlier.

"Why did you suddenly tell me to sleep over?"

"Because I wanted to."

"That's a very convenient reason."

"It's what you always say, Matsuda-kun. 'Because I want to,' 'It's up to me,' 'Just do it,' 'Suit yourself'..."

"I say that a lot?"

"Yeah. It really suits you."

Miyuki was really starting to take after me. It made me happy.

In that youthful yet subtly charged room, I slowly ate the fruit while quietly chatting with Miyuki.

Afterward, I flopped down onto the bed, and she reached over to switch off the lights.

Then, she fumbled beneath the blanket and snuggled into my arms.

"If you go to sleep right after eating, you won't digest it properly..."

The bed was small, but there was still some space left even with the two of us in it.

I gently pulled Miyuki's petite frame—feeling especially small tonight—into a hug, softly stroking her hair as she mumbled her little worry.

"We aren't going to sleep anyway."

"That's true. Aren't you hot?"

There was no air conditioning in Miyuki's room.

It was the middle of summer, so the night air was already thick and muggy. With the two of us wrapped around each other, it was impossible not to feel the heat.

But I thought the heat was more than worth enduring.

The sweat beginning to bead on Miyuki's skin created a slippery friction against me that was intensely erotic. I actually liked it.

"It's fine. We have the fan on. I opened the window, too, so it should cool down in a bit."

"I hope it rains."

"Wouldn't it just get hotter? Plus, we'd have to close the window."

"We could just leave it open a crack. Should we wake each other up if it rains while we're sleeping?"

"Why? To go to a ramen shop?"

"Exactly."

"I won't be able to wake up, though."

"Then I'll wake you. I'm a light sleeper, so my eyes will open the second rain hits the glass."

Miyuki was a light sleeper?

That was true, but only when I wasn't around.

Once she buried her head in my chest and fell asleep, she wouldn't wake up even if I shook her.

"You? You really think you'll be able to?"

At my tone of total disbelief, Miyuki lightly pinched my side.

I felt a sharp little sting from under my T-shirt.

I playfully ruffled her hair in response to her grumbling, then carefully pulled off my T-shirt so I wouldn't bump her.

Miyuki flinched and asked.

"What are you doing...?"

"Taking off my clothes."

"Why?"

"I always sleep without them."

"That's at your house, Matsuda-kun...!"

"Is it any different here?"

"Of course it's different...! What if my mom, dad, or sister comes in..."

"They know we're in here together. You really think they'd just walk in?"

"Kanna might...! To borrow a book..."

"Yeah, right."

"I'm serious."

Honestly, with Kanna's insatiable curiosity, she actually might.

I rested my chin on top of Miyuki's head as she put on her coy act and said, "Who cares if she does? I locked the door."

"...When?"

"When I came into the room."

"What are you planning to do with the door locked?"

"Exactly what you're thinking."

"Let's leave that for later... let's see how things go..."

I found it hilarious how easily she admitted she was having dirty thoughts.

Come to think of it, we had slept together in her room once before.

Back then, I'd told myself I should avoid doing it here if possible, but that resolution had long since washed away.

I couldn't help it when Miyuki constantly acted in ways that turned me on.

Simply put, it was like a force of nature.

"See how what goes?"

She let out a soft laugh at my question and quickly changed the subject.

"Matsuda-kun, I'm just asking... did you have a hard time today?"

She was indirectly bringing up what had happened with Tetsuya.

She must still be furious about it, considering she was bringing it up when there was no need to.

"A hard time? No, not at all."

"Good, then."

"Stop worrying over nothing and take your leg out."

Instead of pulling away, Miyuki pushed her leg even deeper between my thighs.

Finding her playfully disobedient behavior incredibly endearing, I issued a half-hearted scolding.

"We're going to get a heat rash if you do this."

"It's fine, we both put on body lotion. And so what if we do?"

"I'm just pointing it out. Don't get mad."

"I'm not mad, idiot."

"You've gotten a lot more foul-mouthed. Feels like 'idiot' is your new favorite word these days."

"No, it's not."

"Yes, it is."

"I said it's not..."

A touch of whining affection leaked into Miyuki's voice.

It was an incredibly pleasant tone—low and quiet, tinged with a slight, adorable nasal whine.

If she had actually teared up on top of that, I would have completely lost control and pounced on her.

"Sure, sure."

I patted her back like I was soothing a child. Curling into a ball and burying herself deep against my chest, she murmured something that made my ears perk up.

"I wish I'd realized a little sooner..."

She didn't specify what she meant, but it was obvious she was talking about me.

Why did she have to keep driving me crazy like this?

She was someone I truly couldn't help but love.

It would have made me even happier if she had flat-out said she wished I had been her childhood friend instead of Tetsuya.

But given Miyuki's gentle nature, she would never say something like that—she probably wouldn't even think it.

She had likely just been wishing we'd been able to make childhood memories together, and the words had slipped out.

Regardless, her words were wildly arousing. Losing whatever restraint I had left, I slid my hand under her baggy rabbit pajamas.

Starting at her waist, my hand moved up over her stomach and toward her breasts, caressing her with slow, deliberate strokes.

"..."

The same Miyuki who had told me to "see how things go" just minutes ago was now quietly accepting my touch.

No, 'quietly' wasn't right. She suddenly hitched up the leg trapped between my thighs, rubbing against my groin.

Our conversation had gotten her fired up, too.

I could already feel her naked skin beneath the pajamas growing slick with sweat.

Pressed skin-to-skin in the middle of summer inside a room with no air conditioning, the heat was suffocating. But that was a trivial detail. It didn't matter at all.

Lately, our sex had been a bit rigid.

Meaning we'd only ever stuck to the usual routines.

But tonight was special. She was far more responsive than usual, and her affection for me was right on the verge of spilling over. It was the perfect time to try something new.
