I decided to take care of my female student niece for a while. She used to say things like, "I'm going to marry Onii-chan." Even now, she doesn't eat the food I prepared, she lies on the sofa and is engrossed in her smartphone game. …Hey, you can see my pants. I don't know if you're defenseless or you don't see me as a man, but I'll teach you what will happen if you show me that cute butt!
