Hermione

Harry was happily married to Ginny, but recently he had been having fantasies about his female best friend. Maybe it had something to do with all the time he had spent alone with her during the Horcrux Hunt. While she didn't have the body Ginny had, it was her mind that attracted him.

His fantasies had reached a point where he started imagining he was making love to Hermione, instead of his wife. Fortunately, he was able to avoid arousing suspicions.

Harry knew he should be ashamed that he was considering an affair. At least he wouldn't have an opportunity anytime soon.

Suddenly, an opportunity presented itself.
