Becoming Female a Harry Potter Badfic chapt. 14 - Detention with the Blood Quill
Crystal and Draco go to detention for their horny shenanigans, but their punishment is interrupted by the sudden arrival of some unexpected visitors.
Unfortunately we must say goodbye to Umbridge from here on out (until we get to the sequel anyway), as she doesn't appear in the story again. Godspeed you crazy bastard. You will be missed.
And if you think that Draco is going to have any kind of reaction to finding out that his girlfriend is his former worst enemy... then you haven't been paying attention.
