JK Shojo Imouto no In'yoku Choukyou ~Imouto no Mousou wa, Genjitsu e to Aegidasu...

I have a secret "kink" that I can’t tell anyone about.
—I want to be bullied. I want to be bullied and feel aroused—
To my family and those around me, I seem like someone who has no interest in anything sexual.
But the truth is, I have a "masochistic streak"—I want to be dominated, to be treated badly.

—A secret I can’t share with anyone.
Night after night, I sit at my computer, browsing a certain website, comforting myself.
I look at photos of people caught between pain and pleasure, and I touch myself.
I want to experience being dominated for real…

—And finally, I couldn’t hold back anymore.

"Please… train me—"
I left that message on the site.
