Very nice story.
A few problems though,
1. Nothing in my mind could ever picture Severus Snape in leather pants. It is simply not done.
2. You switched a few times betweed past and present tense, which is very confusing and akward to read.
3. The plot moved a bit quickly
Otherwise, very nice. I love the kissing of the tattoo and all that jazz.
another?
Oh! and, I'm not sure what movie the quote is from, but in "Van Helsing" Mr. Hyde says, "Ah, Paris!"
