Well that would really suck. Friends with benefits? Poor Sirius, I don't feel as much for Remus in this fic though, well done. :)

It can feel awkward to write from a character's POV when you aren't attached to them. I have the same problem writing anyone but Remus and, lately, Sirius. I write OC's so they are easy as I create them, but I can't feel much for the other characters.

I really felt how sad Sirius was and could see that Remus was worried but he seemed slightly detached until the 'can we still have sex' line. Then he seemed a bit more rounded. I think you really tapped more into Sirius' emotions than Remus (perhaps because, as you said, you based him on yourself). But it was very bittersweet, which is exactly how the situation should have been. Well done.

It was easier to follow (could be that it's lunchtime now rather than 2 in the morning as well) :-) I'd lose the -dash before each line of dialouge, but that's just me. Cheers for posting this so quickly. It was nice to see what happened after their talk at Hogwarts.
Cheers.

Cuteness.
that would stink...majorly.
Stay friends and have sex? hahahah oh god...
