妹乳すきゃんだる～愛でてよ、お兄ちゃん～（Imochichi Scandal ~Medete yo, Onii-chan~）

"You stupid perverted bro!"
Slap!
"Ahhh... What a mess..."

I saw my sister naked in the changing room. I was so shocked after she had broken all my treasured DVDs that I opened the door in a completely empty state. I never expected to run into her at that exact moment, so it was a miracle that she only threw a towel at me. But the day didn't end so smoothly.

In my room, my sister Sumire was sitting on my bed as if it were the most natural thing in the world.
"...Did you see it?"

It was that story, after all...

"I'm sorry! Yes, I saw it, I saw it clearly! I'm so sorry! Please forgive me! I didn't mean any harm!

I'll do anything if you'll forgive me! So just spare my life..."
"...Anything?"
"Yeah, anything! Anything I can!"
"...Then let me see your private parts too, big brother. Then we're even."
"Huh?"
Sumire's unexpected words made me look up in surprise. But her eyes were dead serious.
