Eep! I was going back through the fest and realized I'd failed to comment on this when it first posted! ::irons hands::
This is so well done. I'm still giggling at the idea of Harry botching an animagus transformation. I love how pale Snape is, and his gaze is so intense Guh. Harry's got a great arse (no wonder Snape's with him ;)), and the glimpse of Snape's cock is a wonderful tease! I like the very dark green curtains draped in the background; they add to the private feel of the scene.
