Recced because: I've been dying to rec this story ever since it first appeared on sizeofthatthing. Teacher/student: a classic kink easy to explore as a 1969 fic in which the Doctor, needing access to school equipment to build his timey-wimey detector, takes a job as a biology teacher. (At Coal Hill School, naturally.) While he works on his lesson plan for basic human reproduction, Martha decides to test his knowledge – and his patience – and gets a very personal demonstration as the answer to her questions. The sex is incredibly hot, but this story is also worth reading just for the banter between Ten and Martha, which is sweet, funny, and very in character.
