Supernatural Series Fanfiction that progresses from Destiel to Wincest to more as it goes on
I'm looking for a series of Supernatural stories that I read earlier in the 2010's ( I believe) that began with a relationship between Dean and Castiel when Dean left Sam behind after the demon blood incident and, as a result, Destiel happened. Dean was forced to leave Castiel, however, to go and take care of Sam to help prevent him from continuing to drink demon blood. Dean enters into a relationship with Sam (Wincest) to help keep him under control. I remember he made Sam leather cuffs with salt in them to help control his urges. At one point, Sam ends up switching places with another Sam from a different universe. After that, Castiel comes back and joins Dean and Sam in their relationship. At the part where I left off in the story (it hadn't been completed yet), Gabriel had decided to join the group, Team Free Will 2.0 if I remember correctly, and they all entered into a relationship together. I know this is all pretty random but I believe it was a series of stories linked together and I thought the last one was named Team Free Will or something. I've tried multiple combinations of these descriptions and can't get anywhere. Please let me know if I didn't do this correctly as this is my first post. Thanks!
