Shizuka approached, Aimi laid in the small bathtub with her butt raised high.

I shook my head. ​​

No need to hide it then. Might as well come clean about it.

(You can do it!)

Shizuku's mouth opened round and the ahoge on her head swayed in confusion.

"Aa-kun always used to bathe with onee-san before. But now you are bathing with that girl..." She covered her face with both hands. "Onee-san feels betrayed..."

"What?!"

Saya forgot everything and hurried toward me. Her eyes opened wide at the scene and without bothering to catch the slipping towel, she pointed at me.

"You! … You are already having a relationship with her?"

"No, it was me who jumped at Asahi-sama. It was my fault."

Aimi tried to take the blame and get away from me. As if I'll let her shoulder this alone. I wrapped my arms around her and hugged her tighlty.

Ah, her breasts felt so pleasant.

"Aimi is my woman." I grinned at Saya and pointed at her chest. "Besides, are you sure about showing me those juicy knockers? I don't mind it though."

She looked at her boobs swaying in the open, and her face turned scarlet.

I gave her a thumbs up. "No need to feel embarrassed. Be proud of your assets, girl."

She quickly picked the towel and covered her front. Her eyes burning with a literal fire glared at me.

"Fucker…"

She harrumphed and stomped out of the room. I shivered from the cold sensation on my cock.

Aimi was cleaning me now. Good girl.

I waited and fortunately, Saya's affection didn't decrease. A sharp girl like her must have already seen through my plan.

My dream for a harem.

I felt like a douchebag for playing with her heart like this. But I'll make it up to her later.

Tsundere was out of the way, so I shifted my attention to Shizuka hugging herself defensively.

"Aimi…"

She moved back from my embrace and I stood up with no shame. My erection already died, but it was enough to attract the attention of Busujima sisters.

*Ding!*

[—Saeko Busujima: Affection +5]

[—Shiori Busujima: Affection +9]

That was a big leap… don't tell me they are after my body now?!

"Hey nee-san, I'm taking up your offer of washing each other's body?"

Her brow shot up and mouth opened wide. "Okay, Aa-kun. Treat me well."

*Ding!*

[—Shizuka Marikawa: Affection +3]

'Geez, if you are a bro-con then say it out loud. Wait, I don't think she understands a thing about love.'

It would be fun tainting — teaching my onee-san.

I made her sit on the wooden seat and snatched the towel away from her. She hid her breast with one hand and covered her crotch with another.

"I can't wash nee-san like this, right?"

I gave my most honest smile. She returned a smile and nodded, glancing at my cock now and then.

"Mm… Aa-kun really grew up."

Yes, I did, in many ways. Smirking, I moved to her back and dropped a bucket worth of water on her head. She quivered from the cold water.

Then with a saintly smile, I groped — cleaned every part of her vibrantly warm and soft body. The inhumane dexterity made my fingers flutter across her body.

She tried to back out, but I sweet-talked her back to the dark side while reciting prime numbers in my head. Her sexy body made it hard to control the erection.

Suddenly, her body started to twitch. I flicked her nipples and pulled back my hands.

"Nnghhh~" She moaned softly. "Aa-kun~"

She hung her head and breathed heavily. Then, a sweet scent wafted from somewhere.

Hold on, did she just climax from her breasts… So lewd…

I lewded my nee-san?

"Nee-san, are you all right?"

*Ding!*

[—Shizuka Marikawa: Affection +9]

She gave a nod despite her body heaving furiously. Saeko and Shiori also walked past me and plopped on the seats. They removed the towel, revealing their bare backs.

I placed my chin on Shizuka's shoulder, taking in her sweet aroma while admiring the sexy backs of twins. Slightly broader and defined than an average woman, which only served to increase their charm.

On Saeko's back, I noticed something.

"Saeko-san… Does that hurt?"

Shizuka asked, pointing at the long diagonal scar on Saeko's back — Scar from a wound inflicted by a blade. A single line connecting her shoulder to her lower waist.
