Hugging the World's Most Beautiful Younger Sister While Sleeping Somehow Turned Her into a Yandere - 13 - Hickey

“Nii-san, Hug me~” 

Just before eleven o’clock, after finishing bathing and getting ready for bed, Aoi entered the bed where Runa was. Perhaps, because she admitted this afternoon that she was a bracon, he got a hug from Runa, who was wearing a negligee.

While her cheeks were flushed with embarrassment, she pressed her breasts, a woman’s weapon, against him.

“gyuu~”

Aoi, who is a severe siscon, is delighted to be with Runa and gently embraces her.

As he held her, Runa’s expression softened, but she seemed embarrassed, burying her face in Aoi’s chest, wanting to hide her embarrassment.

“Nii-san, idiot…”

“Idiot?”

Aoi is surprised when Runa suddenly calls him an idiot. While there have been reasons for such siscon remarks in the past, today’s comment is truly unexpected, leaving him speechless.

“I mean you were getting along with someone other than your sister, even though you call yourself a siscon.”

Her voice clearly reflected jealousy. Moreover, the pinching on his back expressed Runa’s anger. The pinching was intense, causing pain and making it seem like he might faint.

“Since you’re a siscon, you shouldn’t get along with other girls besides me.”

Despite saying she’s just a bit of a siscon, Runa’s possessiveness is strong. If it were another girl, she would have distanced herself as soon as she got close, but since Minami has been a childhood friend from the beginning, there was no avoiding it. They will be in the same grade, and Minami will likely actively approach Aoi at school. 

However, Runa’s face showed that she strongly wished Aoi not to get along with Minami. 

Aoi had to endure it until Runa’s mood improved.

“I’m a brocon, so… I will get jealous if you’re with other girls.”

While embracing her, Aoi could feel Runa’s body temperature, and her blushing cheeks indicate that she wasn’t lying. 

It was easy to imagine that Runa developed a brother complex because Aoi was affectionate since their first meeting. 

Due to her unusual appearances—white hair, skin, and bright red eyes, people had kept their distance from her before, but Aoi’s expression of affection made Runa happy and triggered her brocon development. 

Perhaps due to the impact of not having proper conversations until her mother remarried, she became cold. 

However, with the appearance of Minami, who loves Aoi, Runa seems to have become unable to maintain her indifference. 

It may be that Minami’s appearance made her realize that she is a bracon.

“I want to be with you, Nii-san… if you’re gone, I’ll be alone again…”

Runa looked very sad. Before becoming part of the Usami family, or rather, before her mother remarried, she was always alone because her mother worked from morning till night. 

Without grandparents from her father’s side, and with relatives from her mother’s side disliking Runa’s appearance, she was always alone. However, her mother’s remarriage brought Aoi, a brother, and Runa was no longer alone.

“I want to be together forever… Oww…”

Even while being pinched, Aoi answered with a serious face, or rather, tearfully. 

If she wants to be together, she should stop pinching, but it seems like a punishment for Aoi, who, despite being a siscon, got along with a girl other than his little sister.

“Then show me proof.”

“Proof?”

“Yes.”

Finally stopping the pinching, Ruka moved her hand and brushed back the hair around her nape.

“Since I can’t be with you at school, please put a hickey on me over here. The fact that I am yours, only Nii-san’s sister, even when you can’t be with me, please make me feel that with this hickey every moment.” (Tl/n: OHHHhhhh)

A hickey is a bruise made by kissing, right? Thinking, Aoi looked at her unblemished, pallor neck. 

Albino skin is sensitive and I don’t know what would happen if I kissed Runa in a way that would leave a mark on her skin. It’s unlikely that it would become permanent, but it would be troubling if it looked like a strange bruise.

“I know what Nii-san is thinking, because you always take care of my skin so much.”

When it came to her skin, Aoi tended to react sensitively, so it seems she understood what her brother was thinking as she looked at him.

“Because I’m a brocon, it’s not a problem if you leave marks on me, Nii-san.”

I was surprised to find out that my younger sister was a M, but Runa seemed to really want me to give her a hickey.

The red eyes staring at me conveyed a sense of seriousness.

“If you want it that much, I’ll give it to you.”

“Yes, hiyaa~”

I believed I would never let a scar on her white skin…. but such beliefs were broken, when I thought it was okay to put a hickey on her. 

He put his lips on her beautiful neck, and sucked firmly, making a “chuu~” sound. 

“It’s done, a proper hickey.” 

When I removed my lips from her neck, there was a solid red mark…a hickey.

“I’m so happy desu.” 

Runa touched her neck with an enraptured expression, looking happy to be hickeyed.

“From now on, give me a hickey every day, okay?”

Aoi could only nod at Runa, who smiled at him.
