Looks like blowing is definitely going to be in the picture... ;)
I love Harry's look of abandon here and Severus's passion -- after all he couldn't even wait to get Harry to bed and dragged him under the table! Your use of colours is fantastic, as well.
Severus's hair and unbuttoned buttons are to die for. Brava!
(And I'm sure you'll forgive me for imagining that is not a bolt, but a small webcam attached to my laptop.)
