I'm looking for a fic I read some time ago. I believe Sam and Dean were on a case and they were in a warehouse when Dean touches some magical object (I think it was a crystal) and he gets sent to an alternate reality/universe. In this universe he is married or mated to a version of Sam/Jared and they have kids. He is not treated well by Sam/Jared and I think the oldest teenage son tries to force himself on Dean. It maybe A/B/O as I remember people not being able to control themselves because of the way Dean smells. I think a version of Dean/Jensen is sent to the spn universe and is looked after by Sam. Any help is most appreciated
EDIT. Fic link found in comments
