When Jared Padalecki, life-long criminal, gets released from his five-year stint in Chino, he vows to make a fresh start. That means staying away from the glitz and glamor of Vegas, and going somewhere where no one knows his name. Finding himself in Goodsprings, Nevada, Jared nearly gives up on trying to make a life without crime when no one will give him a chance.
Falling asleep on the lawn of former Master Sergeant Jensen Ackles was the best thing he ever did...

Fifty Cent verse (maybe????, really great story lol)
http://archiveofourown.org/series/52096
Isolated on a secluded property in the Hollywood Hills, Jared and his adopted siblings were raised by a strict nanny and tutors, on the instruction of their often-absent wealthy, religious parents. Jared spent his childhood running away to play in the vineyards and wide open fields of the monastery-cum-seminary school next door, and to Jared, entering the seminary school at eighteen seemed like the perfect way to escape his stifling home. But Father Michael believes Jared needs to live a little before he’ll be ready to take his final vows, so he sends him to work in West Hollywood for a year, at a drop-in and outreach center run by former priest Jeff Morgan. There, Jared meets Jensen, a twenty-year-old hooker who’s been working the streets since he was kicked out of home five years ago. The two become fast friends and Jared soon finds himself questioning everything he always thought to be true about himself.
