On the Perils of Free Advice (гет)

Draco's stuck working as a sex-advice columnist after the Ministry impounded both his family's money and Malfoy Manor. He traded on his sex god reputation at Hogwarts in order to get the job, but there are a few small problems: he's a virgin, and he also has no idea what he's talking about.
When Hermione Granger arrives at his office, irate at the poor quality of his advice, Draco finds himself blackmailed into letting her instruct him on the proper way to give sex advice. She apparently gets up to some pretty creative sexual practices in her spare time, but she's also an irritating, intrusive know-it-all. Draco should be chomping at the bit to get rid of her, so why is he fantasizing about her all the time?
