Kuro Gyaru Imouto no Kimo Ani Ijiri ~Doutei de Sourou Nante Maji Kimoi~

"Haha, what's that look on your face? Do you feel upset that your sister did this to you?" This wasn't the first time Misaki had sexually pranked me. Our parents are often away at work, and she takes advantage of that to torture me on a daily basis, not only in my room but also in the living room, the hallway, and all sorts of other places. If this keeps up, I seriously won't have a place in this house anymore. And not just in this house. If the power balance stays like this, she might just play with me for the rest of my life. I have to somehow regain my dignity as an older brother, or at least my place in the house! If I really try, I can always get out of this situation! So now is the time for me to take a bold fight back, to regain my dignity as an older brother, and as a man! "That's it! From now on, no matter what Misaki does to me, I'll absolutely refuse!"
