I decided to take care of my sorority niece for a while. Before, he often said things like, I will marry you, Onii-chan! Even now, he hasn't eaten the food I prepared, is lying on the sofa and engrossed in playing games on his smartphone. …Hey, you can see my pants. I don't know if you're defensive or if you don't consider me a man, but I'll teach you what will happen if you show me that cute ass!
