I really enjoyed this, especially poor exhausted Severus trying to keep up with Harry's libido and even forgetting his clothes.
However, I tried to picture this: It was red, slightly thick, and purple. and ended up with a very funny mental image! It's a neat trick to be two colors at once :) Someone else happened to be walking through the room at the time, but of course I couldn't explain why I was laughing. Seriously though, thanks for the good read!
