It's really chilling how you took something otherwise so funny and sexy and wove in the canon so seemlessly...arrgh, no, Sirius, no!! Don't doooo it!
Loved this line: When you've known someone since you're eleven, sometimes you stop looking and just figure you know everything. Argh, says so much in so few words.
Also...Sirius was damned well impressed that Remus could say all that in one breath. It boded well for the man's blowjob capabilities. Tehehe! Sirius was snarky and prickly and really seemed to be living in the moment so absolutely; it was great to read from his POV.
