Specifics I rec :)
Jared Tristan! (http://casiedearestfic.livejournal.com/39948.html) So this is totally my favorite. It's cute it's schmoop it's sappy. D'awww (And follow her rps tag because all of her fics are quite good.)

Reflections of Heaven and Home (http://archiveofourown.org/works/186235) is a SPN/RPS crossover with the pairings Jensen/Misa and Gabriel/Jared...

jessebee's Incremental 'verse (http://library-j.livejournal.com/tag/pairing%3A%20jared%2Frichard) series of stories.

I think this is one of my all time favorites for this pairing:

Always and Forever (or Eleven Scenes and Eleven Doctors) (http://hopenight.livejournal.com/21585.html)
Summary: College AU - Jared and Richard meet at college at a meeting of the college's chapter of LGBT , it's not exactly love at first site, but through ups and down and Richard's obsession with Doctor who, they get there in the end.

Blankets Mean Nothing (http://community.livejournal.com/kriotos/1893.html)
Summary: Apparently, in Richard-Land, "staying over for the night" actually means "stay on the couch" rather than "sleep with me in my bed in several senses of the word."

Sugar Storm (http://casiedearestfic.livejournal.com/38206.html#cutid1)
Summary: Richard's moving in. The power is out. And also, there's icing.

Can We Keep Him, Daddy? (http://community.livejournal.com/otp_richred/3863.html?thread=4119#t4119)
Summary: Prompt: Richard hires Jared to babysit his kid(s).

A Little Something New (http://theinsaneeraser.livejournal.com/52077.html)
Summary: Everyones a little tired of the Dean and Cas faze...so Richard and Jared set out to fix this...and it leads to something a little more then they bargained for.
