Um. Seeing as there are no comments and I already multiple-recced on another post, I'm going to hit you with a bunch of DS fic I gleaned from my bookmarks. Before doing this, I skimmed the posts to try to avoid any story you already rec'd and any author you already rec'd (assuming that you would have searched out their stories already and picked which of them you wished to spiff up). I'm sorry if these are duplicates to what you already have saved up; quite likely since it seems as though you're well read in DS... (when I first saw this post I was paralyzed by the fact that I was only supposed to do one rec. *cough* I *really* hope you don't mind).

First of all - the story I keep coming back to and rereading and rereading and was a hair and a push away from attempting to write an alternative POV to one of the scenes for (this would have been bad as I have yet to watch any cannon).

Ardent's "Simply Ray":
http://ardent.mrks.org/simpray.html

Unfortunately, I ship RayK, so the stories I read include him, so I don't have any BF/RV to rec you. I have some BF/RV/RK that I bookmarked:

Etben's "Getting it":
http://community.livejournal.com/stop_drop_porn/9184.html

which has a sequel "Man with the (fucking) fantastic plan"
http://etben.livejournal.com/20961.html

And I have a RayK/RayV rec (has RayK/BF):

ToraK's "Ghost Story"
http://community.livejournal.com/ds_flashfiction/406877.html#cutid1

I also have some crossover DS with Wilby Wonderful (BF/RayK and Duck/Dan):

Lucy Hale's "People and their Rocks":
Part the first: http://lucyhale.livejournal.com/97358.html#cutid1
Part the second:
http://lucyhale.livejournal.com/97767.html#cutid1

Then there are some Dief POV:

Gen: Shay Sheridan's "Second":
http://www.chezshay.net/stories/Second1.html

BF/RK: etcetera_cat's "Learn to Speak Canine in Seven Easy Steps":
http://community.livejournal.com/getfraserlaid/3959.html

There's the two BF/RK fics I think of as "dating and clueless":

Sihaya Black and Chickwriter's "A Fine Romance"
http://www.dueslash.com/archive/1274.html

Kalena's "Dining Out":
http://kalena.mrks.org/dinner.html

Another BF/RK: bodyswap! fic:

etben's "Freaky Tuesday":
http://community.livejournal.com/stop_drop_porn/42461.html

Some possessive!BF with RayK:

This series of BF/RK is fun to read since RayK is a 'damsel in distress' without being very damsel-ly about it all.
Mazeppa's (NovaD's) "The Adventures of Benton and Ray" http://novad.org/Perils/index.html

and Berty's "Stained Glass Saint" (very much like Berty): http://www.squidge.org/dsa/archive/17/stainedglass.html

A very long BF/RK fic:
Journey's "Blueprint": http://journey.mrks.org/fiction/blueprint.html

Happy fuzzy feeling BF/RK:

Berty's "Everybody Loves Benton": http://www.squidge.org/dsa/archive/17/everybodyloves.html

J.S. Cavalcante's "Some Advantages of Plan A, B, and C": http://j-s-cavalcante.livejournal.com/5282.html

Being as I like books - this outsider POV of BF/RayK is fun:

Doll's "Your Books Are In": http://www.squidge.org/dsa/archive/9/yourbooks.html

This is probably too short to rate, but I like how it's constructed and the point and. yeah. I hunted down YouTube vids of Fred Astaire because of this fic. BF/RayK again:

"Dancing Backward": http://www.obliquestroke.com/stories/dancing.htm

*cough* and lastly: Some tentacle fic. *cough* (I probably lost you much further up, yes? Besides, this are also probably too small to really be useful. But they are fun to read. :D)

BF/RayK, crossover with Marvel:
littera_abactor and makesmewannadie's "The Cetacean Situation": http://littera-abactor.livejournal.com/2701.html

and a RayK/Turnbull:
Lynnmonster's "The Alien from Planet Grabby": http://lynnmonstermash.com/crack/planet_grabby.html
