"As an elder brother, I will definitely not look at my little sister and think about perverted stuff!"
"!"
Since I suddenly yelled, Sagiri was shocked.
Then she whispered, like she was looking for a confirmation.
"….Really?"
"Ah, yes."
"….Even if I wore that kind of G-string panty, you will not look down on me and think of me as an ero kid?"
"How could I?" I answered with confidence.
So it's called a G-string panty?
I knew nothing about it! Who could have thought my hikikomori little sister could have something like that!
"Since you doubted me earlier, I will make it clear. I had decided to be a good elder brother to you. I will make you accept me. So no matter how much of a pervert you are, I will not look at you and think of perverted stuff. I will also not have those kind of feelings towards you. And the most important thing is, I will definitely not look down on you."
I raised my chest and spoke my faith.
"That's what an elder brother is."
So don't worry, Sagiri.
To protect one's little sister is an elder brother's duty.
