Im looking for a fic with J2, Im pretty sure it was non au and they were living together. I dont think the fic itself was longer than 8000 words. I remember Jensen walked in on Jared who was naked and then Jared said that now he has to see Jensen naked for it to be fair. Jensen didnt want to do it but then he was frustrated by Jared constantly trying to make it happen and caved in. It led to their first time. Ring a bell? It was on Ao3.
