Draco only landed six strikes. With the belt, he covered Potter’s arse with a beautiful bright red and hints of swollen welts. It’s not a very harsh punishment, because it was not the goal. The goal was Potter would never be able to look at him straight again when he could see Draco’s belt buckle. He would never be able to forget the pain and pleasure Draco gave him with it and Draco would for sure remind him every day.
