Found! Sam & Dean story on Fanfiction

[dianamartins.livejournal.com]

The story I am looking for on fanfiction.net is about Sam who makes a deal with a being to erase Sam from his family's memories and get a new beginning but Dean remembers him. Instead of Sam, Dean gets a sister and Sam is reborn in another family.  He is abused but survives.  He called cops on his family.  Dean never gives up on looking for Sam and he is on the run from Dean.  They eventually meets and wincest happens in the future.  They hunts supernatural and John hires a PI to find out what's going on with Dean.  Does anyone have it?

Found! It's "Secure the Blessing" and the link is below:
