One day...I thought she was doing her homework, so I looked in and saw my little sister rubbing her chestnuts on the corner of the desk...At first, I had no idea if she was doing anything...if her chestnuts were itchy. When I thought that I should scratch it with my hand, my face gradually turned into an ecstasy expression and Iku ... Could this be ecstasy? Did my sister feel ecstasy at the corner of her desk? !
