1) Learning to Read the Signs 2) by Sorceress 3) http://www.masterandthewolf.com/masterandthewolf/stories/learningtoreadthesigns.html 4) The story isn't labeled as a series, but the author did write a sequel to it, which I have listed below. It isn't precisely a mating piece, but Snape does have to submit to Lupin in order to keep a roomful of angry werewolves from killing him. Plus, there is mating in the sequel! ;)
