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

I have a secret fetish I can't tell anyone about. To my family and friends, I seem asexual, but deep down, I yearn to be dominated and mistreated. Every night, I sit at my computer, visiting a dark corner of the internet where I find pictures of people trapped between pain and pleasure—it's how I satisfy myself. But I crave the real thing. One day, I couldn't hold back anymore: "Please… train me." I posted that message on the site.
