Holy crap I think i just died a little. This is amazing.

This.
'...he knows that leaving is the one unforgivable sin left between them.'

And this.

'“I let you go once because I couldn’t stop you. I let you go again because I didn’t trust you. Biggest mistakes I ever made, Sammy.”'

I loved how leaving was absolutely not an option for Dean, how after all of the shit that went down, they are back to being together desperately.

I also loved the carnal aspect, the more animal side.

So, it hurts, but I love it. Great Job!
