Shizuka squeezed my hand right before I entered the room.

"Aa-kun? Do you need me for something?"

"We need to talk."

Shizuka formed a soft smile and opened the door. "Yes, it's been a while since we talked alone. Your lovers just don't leave you alone."

This bro-con sister mine wanted to feign ignorance over our love life.

It's not going to happen.

She sat on the bed and patted the space behind her. "Come, Aa-kun. Tell me how your life is with other girls."

I sat facing her and grasped her hands. "Nee-san, you… are you satisfied with our relationship?"

"W-What about our relationship? Isn't it normal?"

"Oh, normal? What kind of sister breaks into his brother's room and sleeps on the bed where he fucked his woman?"

"T-That was unintentional. I sleepwalked to your bed and hugged you."

I squeezed her delicate hands. "Doesn't it show your subconscious desires? You want to stay close to me much more than a normal sister. Or am I wrong here?"

Shizuka silently stared at me, tears pooling in the corner of her eyes.

"Aa-kun, I… I am sorry." She hugged me and buried her face in my chest. "You are right. I love Aa-kun, as a man. You have such a useless sister that is lusting for his brother."

My chest became wet from her tears. I rested my chin on her shoulder and stroked her hair. "You are not the only one. I also love nee-san."

At my confession, a large heart emerged from her.

*Ding!*

[—Shizuka Marikawa: Affection +13]

"You do. I raised you from when I was ten, so I knew when my Aa-kun started to act weirdly," she looked up with teary eyes and continued, "I always thought Aa-kun had no interest in women when you always turned down the girls' confession in the school."

Me, the bonafide stud, had no interest in women?

She giggled and rubbed her face on my chest. "Then even Rika, the woman lusted after by many men, failed to arouse you. She even tried to stroke your penis when you were asleep. I also tried touching it, but nothing happened."

"I didn't know it..."

"I-It was then… I started to see you as a man…" She closed her eyes and sniffed with a radiant smile. "Your musky scent aroused me so much that I had to accept sex toys from Rika to satisfy myself."

You don't have to go that deep. Someone complimented my scent for the second time.

(High humans are higher on the hierarchy than normal humans. So any human female would be attracted to you instinctually.)

Wait a minute...

"Only family? What about my parents?!"

Shizuka hung her head at my outburst. "...They passed away."

"I see…"

That was bad news. I had a good impression of them, especially my big-breasted blonde mother. Now it is what it is. I accepted it naturally since the last time I saw them was during the 1st or 2nd year of my life here.

A ten-year-old girl raising her brother all on her own—an airhead like her must have suffered a lot. Thankfully, my parents were rich businessmen, so she didn't have to go around for money.

"It must be tough… You endured well until now."

I hugged her tightly, almost crushing her. She did the same as if trying to become one with me.

"Yeah… it was hard… but I don't regret it, not one bit."

"That's admirable."

I leaned slightly to take in her lips. She seemed surprised at first before her eyes brightened up and she grabbed my face.

I tried to keep it tame, but this wild onee-san shoved her tongue in my mouth.

I didn't let her.

She frowned and pinched my waist. However, with my high defense, her fingers barely caused an itch.

Her eyes burned with indignance as if saying how bullied she felt. She broke off the kiss and gave a teary-eyed look.

"Aa-kun, you naughty boy. You always tease nee-san."

I winked at her. "You are so cute that I can't help it."

She glanced down at her breasts. "A grown woman like me is cute…?"

*Ding!*

[—Shizuka Marikawa: Affection +2]

The five hundred students in your fan club will burn any guy who says you are not cute."

She folded an arm on her chest and tapped her cheeks. "Nee-san has a fan club?"

"Yes, it even had more fans than the Busujima siblings."

"Is that true? I thought people disliked clumsy good-for-nothing women like me."

"It's okay, I still love my clumsy nee-san."

"Aa-kun…" She spread her arms, her breasts pushing out of the purple turtleneck as she did. "Give nee-san a hug."

"Sure."

Even a normal hug turned erotic when Shizuka was involved.

"About our relationship."

"You will always be my nee-san."

"Huh?!"

"The nee-san who will fulfill the beastly desires of her little brother. A sister and my lover."

['Shizuka Marikawa' relationship changed to 'Her sweet lover brother']

"T-That is, I am prepared for it." She pushed up my t-shirt and caressed my hard abs. "Aa-kun?"

I shook my head. "Not today. I have a date."

She pouted a little. "Busujima twins? It must be at night, though?"

"Yes."

"Go, leave this nee-san alone."

I couldn't help but chuckle at her cute tricks. She frowned and her cheeks inflated even more, like a balloon ready to burst. That face reminded me of the meme face of Mamako Oosuki.

"Geez, nee-san."

I slid my hands up her breasts and gently squeezed them. Even with the turtleneck and bra, my fingers dug into her soft flesh.

Shizuka covered her mouth with the back of her hand and a tiny moan escaped her lips.

"I already gave my word to Saeko and Shiori or I would not waste any more time tasting these juicy melons," I said, fondling her breasts.

"Nee-san's breasts are getting violated by Aa-kun's hands."

Her eyes had a sultry look, extreme passion dwelling deep within them.

I have to calm her arousal first.

I flipped her body and slipped my right hand inside her pants. Her dripping wet folds showed her arousal.

"Ah… Aa-kun is touching me there."

*Rustle*

A noise came from outside. If it weren't for my senses, I might have missed it.

Someone was trying to peak?

I sneakily glanced at the door. A pair of purple eyes peeked from the slightest opening in the door. Only one woman in this mansion had those enchanting eyes—Milf Yuriko.
