Since I don't have the details of the 'Martha Cothren Teacher Desk Story', it could potentially be a story full of heartwarming moments. It may tell of how Martha Cothren made the teacher desk a place of comfort and learning for her students. It could be about the little things like the way she decorated the desk to make it more inviting, or how she stored students' works on or around the desk, making each student feel special. It might also include tales of difficult times when the desk served as a symbol of stability during challenging school situations.
It could be the Slytherins. They are often portrayed as the antagonists in the Harry Potter series. Maybe they're jealous of Hermione's intelligence and want to embarrass her by forcing her under the desk.

Masturbation is a private and personal act. Combining it with story - telling in a public or inappropriate context is not considered proper behavior. It should be kept in the realm of private and appropriate personal time.
Perhaps it was a form of creative teaching. Standing on the desk might be a way to show the students that there are different ways to look at things.
