searching: specific fic ~ possessive!sam wincest, flirting OMC

[dimpled_dilemma]

I just remembered a fic I read a while ago and forgot to bookmark but now I want to read it and it's been killing me. Basically it's established wincest, and Dean flirts with some cop on a case to get information, but the cop can't leave Dean alone. I remember the omc calling and texting Dean a bunch and it kept pissing Sam off more and more until one day he stormed into the officer's building and told him that Dean was off-limits. The guy still didn't get it and followed the boys to their hotel room where he got an eye full, with Sam and Dean both fully aware that he was watching.

Kinda fluffy but also totally smutty and if anyone knows the fic I'm talking about it would be greatly appreciated! Thank you so much for the help :)
