Wow, that was wonderful! From the first to the last, the expressions, the details, but the story...I could almost feel Harry's resolve, Snape's reluctance, then giving in to what Harry wants, because Snape really wants it too.
And the ending kiss! So hot and sensual - I feel like I'm a part of it (and Harry's glasses! Only someone who wears glasses can appreciate how they sometimes can get in the way!)
