How To Train Your Dragon Male Reader Half Dragon insert

I got a new story, like all my other stories, it is a male reader insert, but I will try to keep it fairly gender neutral but will use Male pronouns, but I will keep what is in your pants.... a complete mystery. This story will take place in the Race to the Edge time line so In between the First movie and Second movie on the Edge Town Island. The reader is part dragon part human and can transform there body parts at will to become any dragon they know of.
