Hugging the World's Most Beautiful Younger Sister While Sleeping Somehow Turned Her into a Yandere - 12 - My Younger Sister Becomes Assertive

After having lunch, Minami received a call from her mother and went back to her own house.

It seems like her family has returned, so it might be a good idea to go and greet them. After all, Minami’s mother took care of me a lot in the past.

“Nii-san, please hug me.”

After finishing the dishes and going from the kitchen to the living room, Runa, sitting on the sofa, looked at me with red eyes, emitting a sweet-sounding voice that seemed somewhat dependent. Her cheeks were flushed, indicating embarrassment.

“Hau…”

For someone like Aoi, who has embraced siscon to the extreme, being depended on by his little sister Runa sent a shock through him, causing him to lose strength. 

Although he managed to reach the sofa somehow, he collapsed towards Runa’s thighs, completely exhausted.

“Nii-san?”

“When Runa speaks in a sweet voice, I lose strength…”

It seems like the impact was too strong due to being a super siscon. 

Especially recently, Runa often uses a sweet-sounding voice, similar to a cat’s purr, causing Aoi to lose strength frequently. It’s probably a voice she would never make in front of anyone else.

“You’ve really become a siscon to the extreme.”

“The best compliment.”

Using his right hand, which had lost its strength, he somehow managed to raise his thumb towards Runa.

“But thanks to that, I get a lap pillow.”

Since he fell onto Runa’s thighs, it created a scene where she is giving her boyfriend a lap pillow. Runa’s slim yet soft thighs are perfect, no blemishes, and he might be able to stay in this position for a while.

“Nii-san is a siscon, so you only have to look at me, okay?” 

I was told this while having my head caressed.

Although the knee pillow was somewhat accidental, the act of Runa herself petting my head, in other words, touching me, is quite rare. 

I usually approach her myself, so there was no need for Runa to initiate physical contact before. 

However, with the arrival of Minami, a childhood friend who is like a little sister, it seems like Runa couldn’t stay passive anymore.

The current lap pillow can be considered a blessing in disguise, and there’s a possibility that Runa might become more proactive in the future. It’s delightful that Runa is taking the initiative, so I’ll just enjoy the lap pillow as it is.

“Are you jealous of Minami, by any chance?”

“I-I’m not. Nii-san is just being too self-conscious.”

Although she denied it, it’s quite evident that she’s jealous, especially after saying that I only need to look at her. 

Runa seemed to want to keep it hidden for some reason, maybe due to embarrassment.

“But, just a bit, a tiny bit, I admit that I’m a brocon.”

Blushing from her hairline to her ears, Runa averted her gaze and confessed that she’s a brocon, even if it’s just a little. 

Perhaps, despite being a high school student now, the realization of having a brother complex hit her after Minami’s comment. 

The reason she admitted it despite the embarrassment might be because Minami was actively expressing her feelings towards me.

“I’m a brocon… so I can do things that other sisters wouldn’t, even if it’s just a little.”

While giving the lap pillow and bringing her face closer, Runa whispered with a reddened cheek. The act of giving a lap pillow, something that other sisters wouldn’t do, is likely what she was referring to. 

Originally, lap pillows are something for lovers to do together, not for siblings, so unless one is a siscon or bracon, there’s no way to be in the position I am now in.

“And so if I whisper in a sweet voice, strength….”

Every time Runa spoils Aoi, he becomes weak enough to lose strength. 

The act of being pampered by one’s little sister is something that makes a siscon happy, and if he doesn’t get so happy about it that he loses his strength, then he can’t be called a true siscon.

“So if I whisper in a sweet voice, I can do whatever I want to Nii-san. I have to make sure that I don’t have to worry about Nii-san being seduced by that person.” 

She seemed to dislike Minami to the point of calling her “that person.” 

“Let’s let big brother enjoy the knee pillow for a while longer and make him even more of a siscon.”

Although I already think of myself as a siscon, it appears that Runa wants me to become even more of one. 

However, despite her smiling face, there’s a slight… just a very, very slight sense that some light has faded from Runa’s eyes. (TL/n: Hehe just the beginning)
