Unlike your other oh-so-charming reviewer, I have no problem with Sam/Daniel.  They go well together, and I'd really love for someone to point out to me where either Sam or Daniel claims that they think of the other as a sibling.  They aren't shipped in canon, but shipping them (or just having them have sex) in fanfic is not necessarily out of character.  Many people have done it well, both here and on other archives.  MaureenT, Thraesja, Zorb, Azar, Amaranth Traces, Joolz, Betty Bokor, etc.

That being said, I am not overly fond of your writing style.  I find it a bit repetitive and somewhat stilted.  As you edit your work, you might want to try reading it aloud to see if it flows properly, or if you're repeating words or images too often.  Pronouns can be your friends.

I applaud you for being creative and for putting your work out there for people to share.  Good luck.

My god, this is disgusting.

You do realize, don't you, that this is not only completely Out of character, since neither had ever had anything other than sibling-like feelings for each other, but also disgusting BECAUSE they only had sibling like feelings for each other?

If you think Sam would do something like that who has always been like a younger annoying brother to her than you need to get your head checked. PRONTO!

And please, stop writing this disgusting SD.
