I'm pretty sure this was a fill for the kink meme. And I thought it was by tehdirtiestsock, or spiders_stars, but I've read through their stuff and alas...

So, young-ish Jensen is on a camping trip, that he didn't really want to go on in the first place; and he's being bullied by some of the older boys on the trip. In the night (or maybe while they're hiking) he runs from the group and comes upon recluse/hermit Jared's cottage. Jared takes him in and is kind/caring to him. IIRC Jared keeps Jensen (willingly) in the end.
