Jensen is funny, especially when he doesn’t mean to be. He’s smart and interesting on so many levels Jared doesn’t know where to start. He has small habits and quirks that should get on Jared’s nerves, but that he actually finds endearing. Also? Jensen wants Jared to fuck him. So why does Jared keep saying no?

There's also an amazingly awesome timestamp here http://felisblanco.livejournal.com/1059448.html
