I love porny fic that starts the reader in the midst of the action to a ridiculous degree. I think I held my breath once I realized what I was diving in to and didn't release it until the end. What I love about this is the tiny, almost inconsequential details that really bring this scene to life -- make it so real. Jeff's chest hairs matted with sweat? I felt sparks shoot up my spine with that small inclusion. Jensen's ragged nails (I can totally see him as a stress biter), I got goosebumps. This was just a delicious overload of sensation.
