I, a Lonely Otaku Was Surrounded by Some of the Most Beautiful Girls on Campus and Was Called Riajuu

“…What should I do…?”

I laid back down on my bed and tried to hold my head up.

But― I couldn’t get my hands around my head because I couldn’t use both of my hands as well even if I wanted to.

It was raining heavily outside, and thunder was occasionally heard.

The sound of the rain is annoying― but it’s probably a good thing because it distracts me.

The reason why I want to distract myself― is because of my little sister.

I looked at my left hand.

Right there was―　

“*Suu―Suu―”

―And there was Sakura-chan’s face, letting out a lovely sleeping sound.

Right now, I’m giving Sakura-chan an arm pillow.

And my free right hand is stroking Sakura-chan’s head.

I really need to stop stroking her head― but when I try to do so several times, she starts to grunt in pain.

Perhaps she doesn’t like the sound of thunder.

If Sakihime and Kirara find me here like this, my life might not really be….

I don’t know how this happened― but it reminds me of what happened a few hours ago.

Part 2

“―It’s suddenly raining and you’re soaking wet, Onii-chan…”

Sakura-chan, who was soaking wet from the rain, looked at me with a wry smile.

Perhaps it’s the rain that’s soaking her, but she has a different look to her, one that I think is a little more sexy.

…She was supposed to be a loli girl…

In addition, because Sakura-chan was wearing white clothes today, her underwear was visible through the rain.

When I noticed this, I hurriedly turned my face away.

S-Sakura-chan… has a young face, but she’s wearing very mature underwear…

It’s not a cute underwear that Sakura-chan was wearing, but a black-based underwear that an adult woman would wear.

A-Ah, that reminds me, people with large breasts don’t have many choices in cute underwear, so they have no choice but to wear sexy ones…?

B-But Sakura-chan is wearing such a thing―

“Onii-chan…?”

“Ha―!?

When I was unconsciously trying to imagine something bad based on Sakura-chan’s earlier appearance, Sakura-chan called out to me.

I couldn’t look at Sakura-chan even now, so I turned my head away and spoke.

“It was a bad idea to go out without looking at the weather forecast today…”

“Yeah, that’s right… But Kirara-senpai came to pick me up early this morning, and I couldn’t keep her waiting too long.”

Yes, until just now, today, Kirara and Sakura-chan had been playing together.

After the dispute between Sakihime and Kirara yesterday, Kirara decided to go back to her house right after Sakihime left.

Of course, I couldn’t let a girl like Kirara go home alone at night, so I walked her there.

I talked to Kirara for a while― and she said that she was still troubled.

She had promised me that she would make amends for the rest of her life, but she still hadn’t been able to do anything for Sakihime.

When Sakihime told Kirara that she could forgive him if they were friends, she realized what she had to do.

But it’s a very tough and long road.

As for Sakihime’s suggestion to be friends― I don’t think I can consider someone who has done so many horrible things to me as a friend.

And from now on, if I get involved with them, I’ll have to put up with their unpleasant attitude, and I’ll probably have to go through a lot of pain.

If that’s the case, I think it would have been easier for Kirara if I had only helped her when she was in trouble.

But both Sakihime and Kirara knew that, and both of them had decided to do so.

If that’s the case, it’s not my place to interfere, as I’m only halfway involved.

But until Sakihime says she forgives her, Kirara will have to continue to make amends to Sakihime…

In the end, I walked Kirara home and went right back to my house.

After all, I was worried about leaving Sakura-chan alone.

In fact, Sakura-chan should have come with me, but I guess she was worried about Kirara.

Even though she may be the youngest in appearance and age, she may be the most mature of the siblings.

…What should I do… Sakura-chan might be the most mature, but we’re siblings so it’s not okay…

I went home that day with such anxiety about my life.

The next morning― Kirara asked me to go out with her.

Sakura-chan was also interested, so we decided to hang out with Kirara.

We also went to a pet store for Sakura-chan, who is an animal lover, and Kirara and I were soothed by Sakura-chan’s melancholy over kittens.

Yes, I’m a cat lover, but this might be the first time in my life that I didn’t even look at a cat.

After playing like this until around 6 p.m.― it suddenly started to rain.

And it wasn’t just a downpour, it was raining so hard that it felt like a jungle rain.

We chose to go home without buying umbrellas because our house was close by, and we got soaked to the bone.

Sakura-chan was going to catch a cold if we didn’t get out of the house, and I didn’t know where to put my eyes, so I decided to have her take a bath.

“Sakura-chan, go take a bath so you don’t catch a cold.”

“But what about Onii-chan?”

When I urged Sakura-chan to take a bath first, she looked at me with concern.

I think she’s worried that I might catch a cold.

She’s a sweet girl after all.

“I’ll be fine later, so come on in first.”

“But…”

“Just come in, okay?”

When I patted her head, Sakura-chan looked at me with a surprised expression.

But her face immediately changed to a happy one and she went straight to the bath.

Well, I say bath, but it was a shower.

But― I was surprised at my own behavior.

I… stroked Sakura-chan’s head, didn’t I…?

No, it’s not the first time I’ve done it, but it’s the first time I’ve done it myself, and more importantly, I did it unconsciously.

I couldn’t believe what I was doing.

After a while Sakura-chan came out of the bath and we took turns taking a bath.

As I was warming myself up in the shower, lightning started to strike outside.

It’s only a short span of time, and it’s close by.

But I’m not afraid of lightning, so I don’t really mind.

However― it seems that Sakura-chan was not.

“W-What’s wrong…Sakura-chan…?”

After I got out of the bath, I called out to Sakura-chan, who was shivering with a blanket wrapped around her body, which I didn’t know where she got it from.

“Onii-chan―!”

Sakura-chan, who had noticed my presence when I called out to her, slipped out of the blanket and hugged me.

“Eh, What’s the matter with you!?”

“I’m scared…”

“Eh, you’re scared?”

“Yeah…Hiii―!”

Sakura-chan let out a small scream as the lightning struck nearby again.

Then she hugged me tightly.

Oh… scary, is that lightning…

I’m sorry to say that even though Sakura-chan was on the verge of crying, I still managed to find her very cute.

“Are you okay?”

I asked, and Sakura-chan shook her head to the side, buzzing and shaking.

She seems to be quite uncomfortable with thunder.

“Onii-chan… can you give me a hug and pat my head…?”

Sakura-chan looked up at me with tears in her eyes and begged me to do so.

I can’t say no to a request from such a cute little sister, so I do as Sakura-chan asks.

When I hugged Sakura-chan’s body and patted her head, she looked relieved and put more strength into her arms, hugging me.

…Oh no, what should I do…?

Sakura-chan is just too cute…

I was already filled with the cuteness of Sakura-chan in my heart.

However, I had to cook a dish because I was supposed to have dinner at home today.

Since Sakura-chan wouldn’t be able to cook in this state.

I’ll cook for her instead.

So I told Sakura-chan to get away from me while I cooked― but she shook her head even more than before.

Then she pushed her face into my stomach.

I was surprised at how much it hurt.

In the end, we came to a compromise: Sakura-chan would hug my back while I cooked rice.

After that, Sakura-chan never left my side while we ate or watched TV.

I thought Sakura-chan was very cute, and to be honest, I was very happy to see her like this.

But― Sakura-chan didn’t want to leave until it was time to go to bed.

“U-Umm, Sakura-chan…? You’re not going to sleep with me, right?”

“No… I’m going to sleep with Onii-chan…”

Sakura-chan, who refused to leave my side, began to complain.

“No, you know what? That’s not a good idea.”

“Onii-chan doesn’t like… Sakura…?”

Sakura-chan gazed at me with tearful eyes.

If it had been me before, I might have nodded my head in agreement, but I couldn’t do something after yesterday that Sakihime would have been upset about.

I don’t know what’s going to happen if she finds out that I slept with her little sister, who is very dear to her…

“I’m sorry, I just can’t do it.”

“Ugh… Onii-chan’s terrible…”

“Ugh―!”

I felt so guilty when Sakura-chan said that with a tearful face.

“By all means… No…?”

When I felt bad for Sakura-chan, she asked me this question with an upward glance and then hugged me even more tightly.

…I can’t keep this up anymore…

“Okay, fine…”

Sakura-chan’s cuteness got the better of me, and I finally said yes.

“Thank you…!”

Sakura-chan said, and put more strength into her hugging arms.

I guess she’s really afraid of thunder.

It was nice to sleep with Sakura-chan― but for some reason she asked for an arm pillow and also asked me to stroke her head to distract her from the thunder.

Sakura-chan broke my heart once more, and I followed her request and gave her an arm pillow.

We had a great time talking together until Sakura-chan fell asleep― but what if Sakihime and Kirara find out about this…?

I couldn’t fall asleep that night because I was still worried about that and Sakura-chan was still with me, while hugging me in her sleep―.
