Ok so a long time ago I read a Harry Potter story mostly about Snape and Hermione. Hermione gives Snape her virginity due to a mission they are both sent on. Then later in the story Snape becomes her dominate. Then Harry and Ron catch them. The story ends basically with Ginny and Harry going to Snape and Hermione for help with their dominate/submissive lifestyle (Ginny is the dominate). Anyone have any idea what story I am talking about?
