If there's a formula for taking Snack way beyond hatesex and still keeping Snape and Sirius in character, you've obviously got it scribbled on your chalkboard. The sex was hot and the characterization was believable -- which is what I totally want in Snack fics. What started as just physical one-offs turned into a relationship very smoothly. Sirius's anger when he discovered that he was Snape's "assignment" was just delicious, as was the final scene. Making this Sirius's POV was a very effective choice, and for as much as I love full-on anal sex, having them not quite go there (yet) was hot and realistic. Brava, Mystery Author! Writing Snack that's neither hate-sex nor romantic fluff but just a great all-around fic is quite the achievement. :D
