In this chapter, Hermione is once again goaded into seducing her professors, which she does in naive hopes of uncovering sexual corruption at Hogwarts, but gets quite a shock when Professor Snape himself makes a pass at her butt as a result. Meanwhile, the Genie himself proceeds even further in corrupting Cho and Luna, and Astoria is encouraged to put her first curse on Susan Bones, giving us all a delightful view of the girl's mighty udders.
