Something I'm Not Allowed to do at Hogwarts

Written for the 'Things I'm Not Allowed to do at Hogwarts' challenge. Lighthearted and a little on the fluffy side, second years Draco and Blaise have to serve detention with Professor McGonagall when she catches them breaking rule #4 of what you're not allowed to do at Hogwarts. Rating is just to be safe for extremely minor, very brief suggestive dialogue.
