Jensen knows from the start that moving in with a near-stranger is anawful idea, but the true magnitude of his mistake hits him like asledgehammer after a few months of rocky cohabitation, when he realisesthat he's head over heels for hiscollege-dropout-turned-struggling-actor roommate, who goes by the nameof Jared and is oblivious, obnoxious, and straight.

Lost and Found (http://mediaville.livejournal.com/57649.html)

Jensen Ackles is a shy, overweight songwriter whose body issues haveprevented him from forming any real personal connections, and atthirty, he’s still unsure of his sexuality, and still a virgin.

Topspin (http://lazy-daze.livejournal.com/567316.html)

WithPadalecki's new reckless style, explosive power and natural gracepitted against Jensen's own beautifully strategic, strong andwatertight game - all that's for sure is that this is going to be oneWimbledon final match not to be missed. With a media-painted rivalryturning into a mutual dislike that's almost as explosive as thebadly-hidden attraction sparking in the air, there's more than a tennisball flying between them.

True Colours

Just finished rereading "In From The Cold" it is so wonderful I am moved beyond measured every time I read it.

Another fic I've read again & again is "Lingering In The Golden Gleam"
excellent story .

Here's a comm that is organized by fic thematic. I'm forwarding you to the AU tag (http://community.livejournal.com/j2_recs/tag/au) but I recommend the entire comm because it's so well organized. Easy to find what you are looking for. ^__^

Many of my favorites have already been listed. I'll give you two from this year's Big Bang that went right to the top of my list:

In Becoming Who We Are (http://elizah-jane.livejournal.com/84873.html) by elizah_jane

Everybody's got a love/hate relationship with their jobs. But for Jensen Ackles, top Cupid in the nation, after a hit goes wrong it's just a long, downhill slide from there. Caution: an ungodly amount of swearing, sarcasm, and schmoop in which Chris Kane is an awesome best friend, Tom Welling's the vacuous son of Zeus, Rosenbaum is Rosenbaum, and Jensen has a penchant for Plans.

Every Labor Day weekend, thousands of geeks like Jared Padalecki, Terry Pratchett fanboy, and Jensen Ackles, self-professed Neil Gaiman devotee, descend on Atlanta, Georgia for Dragon*con. When these two strangers arrange at the last minute to share a hotel room at Dragon*con 2009, it leads to some Interesting Times. Sparks fly between them from the get-go, and though they may not be made of Stardust, they're definitely Good Omens for things to come

The tale of a comic geek, his matchmaker friends, and the tall, hot guy who can't stand the sight of him.

http://ivy03.livejournal.com/373519.html
It's Jared's first summer as a camp counselor. He didn't know what he was expecting at Camp Mahina, but it certainly wasn't the frequently shirtless sailing counselor with the perfect smile—who doesn't know he exists. Camp means living in close quarters with no privacy at all. How can Jared be expected to hide his crush when Jensen's everywhere he turns?

http://vamphile.livejournal.com/225515.html
Jared is a Native Resident on Mustang Island. Jensen is Staying for an Extended Vacation. They like each other… a lot.
