I loved this fic, especially Luna. She's the one character I've loved more because of the films and yours is just an utterly wonderful characterisation of why I love her, and you got in her smartness, which makes me really happy.
All the other characterisations were fantastic too - naive Harry, snarky Snape, funny Ron and assured Hermione.
Sarcastic kissing indeed, and Harry being glad he's not the only one with a hard on - brilliant, made me laugh so hard.
And the ritual itself, the actual sex was just so hot too. And it seemed so real, and not utterly perfect, yay!
The ending = love! I'm picky about endings, but this was just fantastic. Methinks the boy (okay man) doth protest too much!
