Hugging the World's Most Beautiful Younger Sister While Sleeping Somehow Turned Her into a Yandere - 15 - Getting Changed by My Little Sister

“Nii-san, gyuu~ gyuu desu~”

As soon as they arrived home and without even changing out of their school uniforms, Runa stretched her arms wide in the living room, as if she wanted Aoi to embrace her.

When Runa is in a clingy mood, her vocabulary seems to diminish slightly. However, since she expressed the desire to be hugged, Aoi enthusiastically lunges towards her.

“Ouch…”

Just like a week ago, his attempt was evaded.

And because he tried to embrace her forcefully, just like a week ago, he hit and twisted his right wrist on the floor.

An area that has recently experienced a sprain is susceptible to twisting for a while.

“Why did you dodge today, unlike last time?”

“Well, even if it’s different from last time, when someone comes at me with such force, I reflexively avoid it.”

Holding his painful right wrist, Aoi inquired, and he received a reasonable response.

Certainly, this time he came at her with quite a bit of force, so it was natural for Runa to avoid him.

Reflecting on this incident won’t help much now, as he’s too preoccupied with the pain.

“Even though the bandage just came off, now I have to put it back on. Is my brother’s learning ability zero?”

Sighing heavily, Runa retrieved the first aid kit stored in the living room cupboard.

She seemed to think, “he won’t go to the hospital anyway,” as she wore an expression of exasperation.

Even though she’s been acting spoiled a lot lately, her fundamentally cool demeanor remained unchanged.

“Come on, sit down. I’ll take care of it.”

Instructed to sit on the sofa, Aoi complied.

Runa might usually say, “Take care of it yourself,” but even though there’s a coldness, she’s also showing some kindness.

Having declared herself a brocon, she probably couldn’t leave her injured brother alone.

“Well then, excuse me.”

Although it’s usual to face each other when administering first aid, for some reason, Runa sat on Aoi’s thigh as if she were snuggling up to a boyfriend.

She then brought Aoi’s right hand in front of her and began to administer first aid.

“It’s red again. I’ll put a wet compress and bandage it.”

Although moving the wrist a bit caused pain, he doesn’t say anything since Runa is taking care of him.

Runa, who took out a wet compress and bandage from the first aid kit, adeptly applied the wet compress to the reddened wrist and wrapped the bandage.

Since Runa is generally dexterous, she manages to wrap the bandage as skillfully as the nurse did during the last visit.

Although the freshly applied wet compress felt uncomfortably cold, it will probably stop bothering him after a while, just like last time.

“By the way, with your right wrist hurting, can you change clothes properly?”

Cheeks blushing, Runa asked.

“If I endure the pain, I’ll be fine.”

The most troublesome part of the last sprain was changing clothes.

Since changing clothes inevitably required the use of both hands, he had to endure the pain and change.

“So um…..this time I asked for a hug and avoided you again, so I will he-help….you change.” 

“….what?”

Aoi froze at the unexpected words.

Lately, Runa has become more affectionate, but he couldn’t have anticipated her offering to help him change clothes.

However, Runa is not the type to lie about such things, so if she offered to help him change, she meant it.

“I’ll appreciate your help.”

Surprised but with no reason to refuse, Aoi headed to his room with Runa.

☆　☆　☆

“Auu~….changing Nii-san’s clothes…..”

Runa, red up to her ears when she came to the room, reached for the school shirt Aoi is wearing with a sense of trepidation.

She slowly unbuttoned his clothes, as sure enough she was still embarrassed to help her brother change. 

But she’s the one who said it, so no matter how embarrassed Runa is, she’ll do her best to help him change.

Ao spread his arms slightly to the left and right as she finished unbuttoning all the buttons.

“uuu…”

Aoi wasn’t wearing anything underneath his school shirt, so Runa could see his bare upper-half now… She averted her eyes in embarrassment.

Any normal person would be somewhat used to seeing a man’s upper body at the ocean or pool, but Runa wasn’t used to it, since she didn’t go to the beach or pool due to her constitution.

In any case, she seems to have a reluctance to see the opposite sex’s body.

“Please hurry up.”

I would like to savor forever the dreamlike moment of having my sister dress me, but if this goes on too long, I will lose my strength and not be able to endure it.

“I know…but…”

Runa buried her face in Aoi’s chest, as if she wanted to do this no-matter-what before getting him dressed.

Up until now, it had been through clothes, but this time, because of the direct skin contact, so I felt more euphoric than I had ever felt before.

“Huh?….Nii-san?”

“Being spoiled by Runa makes me lose my strength…”

Though Aoi managed to avoid collapsing to the floor, it seemed as if he was relying on Runa for support in the mirror. Despite Aoi being petite, it was challenging for Runa to support him due to his lack of strength.

“Nii-san, try to hold on.”

“C-Can’t do…”

Aoi didn’t collapse to the floor thanks to Runa’s support, but if that support were to give way, he would naturally fall. Unable to muster strength, Aoi ended up on the floor, with Runa supporting him. Fortunately, Runa didn’t bear Aoi’s entire weight.

“Nii-san, you’re heavy, please move away.”

“For a while, it’s impossible…”

While it wasn’t ideal to stay in that position, Aoi found it challenging to regain his strength and move. After remaining in that position for a while, Runa helped Aoi change clothes.
