Aargh, second attempt at a comment, my computer ate the first one...
This is lovely. I love the expressions, and I love the way you didn't feel impelled to show everything, just because they've had sex. Harry would keep the stockings on, and Severus wouldn't want to cuddle afterwards. Not at first, anyway.
This is a perfect accompaniment to the fic - which by the way, thank you for pointing me towards. You have captured the mood of the piece beautifully.
