Saturday. Today was a date with my sister, so we were at the aquarium.

“I hadn’t been to the aquarium in a long time. Maybe since elementary school.”

“Me too. So I’m looking forward to it.”

We arrived as early as possible, but there was already a line at the entrance. Since it was a holiday, there were many people with children and couples.

After standing in line for about 10 minutes, we received a pamphlet and entered the aquarium. It was surprisingly dark inside, which made me nostalgic.

“Let’s just follow the route and see what’s there.”

“I guess so. Let’s go that way first.”

The first thing we saw was the jellyfish tank. The floating jellyfish and the lights created a mysterious atmosphere.

My sister looks around like a child visiting an aquarium for the first time, which makes me smile a little.

“Jellyfish are pretty cute. They are so beautiful.”

“I think so too. I guess it changes my impression of jellyfish.”

I couldn’t help but smile as my sister happily informed me. I looked at the jellyfish tanks one by one, and it seemed like I wouldn’t be able to see the other tanks at this rate, so I called out to my sister.

“Nee chan, let’s go to the next one, shall we?”

“Can’t we just watch a little longer?”

“It’s just the beginning. I want to see the other tanks. Besides, if you like it, we can come back later.”

“Kyaa ! T-that’s right. Let’s go.”

When I tried to hold hands with my sister and start walking, she gave me an unexpected reaction, which made me feel a little embarrassed. I scratched my head with my other hand and looked at her face. It’s too dark to see much, but her cheeks are a little reddish and her eyes are downcast.

I don’t want to ruin the mood by being embarrassed, so we start walking hand in hand.

While holding hands, we walked around the small tanks and tunnels, and next we went to the big tank, the main and largest tank.

I thought it was an amazing sight to see the swirling sardines, rays, sharks, and other large fish that I had not seen in a long time.

My sister thought so, too, and we stared at the tank in silence for a while.

“I wondered if it was safe for sharks and sardines to be together. Don’t they look edible?”

After a while, my sister came up with a question.

“That’s true. But I’ve never seen one being eaten.

“Right. It’s strange.”

Saying that, she moved closer to the tank and put her face as close to the tank as she could to get a closer look. I followed her lead and approached the tank, putting my hands on her shoulders and covering her from above to look at the tank.

Then I heard a small moaning sound from below, and I hurried to look down.

I couldn’t see much from above, but at least I was sure that my sister was covering her face with her hands, her ears reddening. I’m getting warm looks from people around me, and I’m getting embarrassed again.

I was getting kind of desperate, and I whispered in her ear, [You look pretty too, Nee chan.] and she blushed all the way up to her neck, so I thought I had gone too far and took her to a place where there were few people and benches.

“Sorry, your reaction was too cute.”

“Geez, don’t call me that. I’m embarrassed.”

My sister turned away and said that, so I felt like being mean to her again and muttered [cute].

“Yuuki, you stupid, stupid, stupid.”

“I said I was sorry.”

I apologize and mumble [cute] to her again.

Then my sister blushed up to her ears again and buried her face in her knees.

“That’s not fair, Yuuki. You’ve never said anything like that to me before, and now suddenly you’re saying it over and over again……”

“So it’s better if I don’t say it?”

I said so, and my sister looked up a little and looked at me.

“I didn’t say that. I was just embarrassed. I’ll get used to it.”

“I don’t want you to get used to it. I want to see more of this kind of reaction.”

“Yuuki, you’re acting strange today. You seem a little bit aggresive.”

“I’m just trying to be honest with myself a little bit more.”

After saying that, I stood up from the bench and started walking holding hands with my sister again.



After that, we had lunch and watched the dolphin show before returning home. We sat in the front row, which was what my sister wanted, and as a result, we both got soaking wet.

I wondered why she chose to sit in the front row when she knew she would get wet, but all she said was, [That’s part of the fun].

Riko was a little sulky when we got home, so we decided to go on a date somewhere after next week. Her mood was a little better when I gave her a souvenir, but she still seemed unhappy.

And then I lay down with my sister again and fell asleep.

☆.

Sunday. Today was a date at home, which meant we were going to hang out at home. Riko sulked and went to hang out with her friends, and my parents, guessing what I was thinking, said, [We’re going on a date for the first time in a while] and went off somewhere. I’m glad they seem to be getting along so well.

I don’t know what I’m going to do, but I’m getting ready at a slower pace than usual, and when it’s past 10:00, my sister and I are done getting ready.

“Come on, let’s play this, Yuuki.”

“Oh, games, huh.”

My sister brought some game softwares and a game console in her hand and started to connect the console to the TV. The games she brought were a racing game of a certain sibling and a big brawl game.

Both were things I was good at, so I might be able to beat my sister at these.

My sister says she wants to practice, so I watch her practice. She seems to be playing the racing game first and is operating the controller with a slightly familiar motion. I watched her as she moved her body sideways on the curves, trying to resist the urge to shove her.

“It’s a game, Yuuki. Don’t go easy on me.”

“Really? If it’s okay with you, Nee chan, I’ll do it.”

On the cue of three, two, one, I decide to make a dash for the start. However, I made a slight timing error and missed. This hurt.

My sister had made a solid start dash and was already in the lead.

“Yuuki, I wonder if you’ll be okay with that.”

“….You better remember this, okay?”

Two laps to go. I had succeeded in closing the gap with my sister, but I couldn’t close the gap any further. I’m going to lose at this point, so I decided to use the other way around.

Just as my sister was approaching a curve, I called out

“Shiori.”

“Huh?! Ah !”

As usual, my sister’s body was still moving on the curve, so by making her move at the right moment, she fell onto my thigh. The momentum caused her character to fall in the game as well, and I took first place and kept my first place position to the finish line.

“Yay, I won !”

“It’s cheating, you’re cheating. It’s invalid ! Let’s play again.”

“All right, all right. I won’t do it again.”

She looked frustrated and said so.. The game continued until almost noon, and ended when I said I was going to have lunch.

By the way, I won all the games.

“I didn’t win a single game…….”

“I’m sorry. I’ll go easy on you next time.”

“I don’t want you to do that. I want you to do something for me. Later, please.”

I didn’t think it was necessary to ask her now, so I cooked and ate lunch with her. After we finished cleaning up the dishes, I asked her what she wanted me to do.

“What do you want me to do?”

“Well, I want you to pet my head, give me a back hug, give me a thigh pillow, and then…….I’d like you to do that for starters.”

“That’s a lot……”

There was no need to refuse because it wasn’t anything strange (I couldn’t refuse in the first place), and at my sister’s request, I decided to do it in her room.

She said I could do the thigh pillow and head patting at the same time, so I started with a back hug. I’m a freshman in high school, so I’m still growing. Compared to a few months ago, I was bigger than my sister.

I was almost able to completely cover my sister, who’s sitting between my legs (she is petite to begin with).

She was comfortable to hold, and her body temperature gave me a sense of security. After doing so for a while, I let go of my sister and moved.

My sister fell down on my thigh. I wondered if thigh pillows were supposed to be done in a prone position. I wondered, but if that’s what she wanted, I had to do it.  It’s easy to pat her, so it’s not so bad.

I thought the same thing when I touched her hair last night (around 1:00 a.m. on Saturday), but her hair was smooth and comfortable to touch. I stroked her head while enjoying the feeling of her hair, and when she was about to get up, I stopped my hand.

“That was close, I was about to fall asleep.”

“It’s okay for you to sleep though.”

“No, there’s a reason why I shouldn’t sleep. Yuuki, this is my last request. Yearn for me.”.

“….Eh?”

Was this what she was stuttering earlier? I think she said something like [I’ll be careful from now on] yesterday, but I wonder if it was a lie. 

Anyway, I wanted to ask her why, so I asked her.

“Why? Didn’t you say you would be careful?”

“That’s true. Hey, if I say house date at an empty house on a holiday, would you do that?”

“Even if you say that, I don’t understand. It’s the first time for the three of us.”

It was certainly the perfect atmosphere, but I didn’t know what to think of it because I had no experience. My sister should be the same in that she has no experience.

I was groaning unconvinced, and my sister forced me to push her down.

“Anyway, I want to do something that’s like being a lover. Please, Yuuki.”

“I understand.”

I could hear that she really wanted to do something like a lover, so I was satisfied with that, and then I kissed her on the mouth first.
