The old sex ed prompt, Harry Potterfied with a more appropriate age range of students. The best part is that the world of Harry Potter is stupid enough that it would be reasonably plausible in universe. Seduce your students or maintain your charge to teach them. Why not both? The choice is yours! Each girl has unique looks and personalities that change if you seduce them. Be sure to update your lorebook accordingly.
Note: some concepts were liberally borrowed from other HP smut media. Sue me.
