Hi there!

I'm looking for a specific Dean/Cas sex pollen fic, where they're cleaning Bobby's house/spare room/library (something like that) and Dean touches a chest that said "do not touch", which then opens and curses Dean and Cas with a mate or die curse. I know that at some point Dean goes to the kitchen to make him a sandwich naked and Sam sees him, and I also remember that in the end Dean was so tired that he just slept through the sex while Cas kept going.

I'm not quite sure if they were in pain when they weren't touching or if that was another story.

I've been looking for this story for quite a while now and I really hope one of you guys can link me to it! :)

ETA: Found it! :D it's Do not touch by bauble :) Many thanks to mercury_alice :)
