It sounds like "Runaway" by Sparky1459 but he seems to have pulled his stories.
I'd say Runaway by Let's not tell Jane, also removed from here (same author, possibly/probably?); the characters 'Duncs' (Duncan) and 'Aims' (Amy) live just outside Beverly in Yorkshire and made a cameo in Oyster50's Community (as noted in his blog entries for 11,12th July 2014). Over 1MB in nearly 30 chapters, but a google for a unique phrase gave no hits so seems to be gone - although Google does FU some searches: compare results for searches (including quote marks):
"They were looking at me as if I was Jesus Christ right down from the cross"
- one result (plus dups) for Al Steiner's 'Doing it all over'
"Jesus Christ right down from the cross"
- no results even though it's a substring of above.
ETA: I've just given Google some feedback for that.
ETA 2016-10-28: now there's one result for the second, this post.
same author, possibly/probably
Same author for sure; I've got it saved twice, once under Let's not tell Jane and once under Sparkyman1961
Any chance you could send me an epub copy of the story? I love Oyster's work and the chapter(s) with Duncs and Aims has me curious.
