Anything with the general theme of Jensen being coerced/forced into porn and a couple of specific ones:

1. Jensen takes a job not knowing it's for hardcore porn (he was taken there by his agent who owes the company money or something). Some of the porn is J2, some J3. (I may be mixing this next part up with another fic..) In between filming days, Jensen is kept under lock and key by Jared who plays hardcore sex games with him whether he wants to or not. (This one found in comments!)

2. All I remember of this one is one scene where they bring Jensen into a warehouse with a manky filming scene set up in the middle of it and he really doesn't want to do it. Maybe it involved dogs? Or multiple men? I don't remember what Jared's involvement was in this one, whether he was part of it or made it easier for Jensen or took him away or what.

He may or may not have been underage in either one, I don't recall, but I added the tag just in case.
