Hermione always was the brightest witch of her age. It made her exceptional at a lot of magic: potions, hexes, blowjobs. Oh and transfiguration too. It's no secret in the castle she likes to fill herself with new kinds of knowledge. For example: a spell that can transform a wizard's "wand". Poof, it can be as thick as a dragon! Or with a flick, ka-wow! It's a juicy throbbing Hippogriff dick! Learning has always been the most fun for her. Did you know drooling all over the slimy cock of a basilisk can break curses! Or you can put Trolls to s!eep with a tight moist hole! There are just so many ways to care for these Magical Cocks! It sure looks like Hermione has a lot of studying to fit in; she'd better get cramming
