I love dragon fics where Harry or Draco are the dragon in question and there where two that stood out for me but since my laptop was fixed all the links got lost this is what I remember
1.
After the war Harry is always with Blaise and they have some sort of bonding bracelets people think they are together but i a reunion of slytherins its explain that it is a sibling bond. Harry is sad because he loves Draco but he was promised to the Draconian and can't be with anyone else. So Snape and Blaise are always protecting him. Draco is the Draconian.

2.I the Malfoy family there is some sort of curse that makes the first born transform at certain age into a creature or animal. Their names are selected by a Magic tapestry and it reflect in what they will transform, they have mates. Draco is a dragon and is after Harry, the order take Harry to the headquarters to protect him. Harry and Draco go together to Hogwarts and have their own rooms. Draco lays an egg(the egg is made while flying with the union of their magic), the name of the baby (Leo) appears in the tapestry and I think Narcissa sees it. I know that the egg needs both parent magic to grow, Harry gets weak and to be able to sustain the egg he gets transformed into a dragon. I think it is in that form that he kills Voldemort. I know that at some point H/D are in a forest in a tent and that Dudley protects the egg for a while. Dragon Hunt by
sweettartashPlease if someone can help it will make me extremely happy.
Ps. I think that the first one is not graphic but harry seems more submissive and in the second one there might be switching at some point. I don't really remember so forgive me if there is top!Draco, I usually don't care who tops.......
