once again: help finding a story

[mickeym]

I'm looking for a Sam/Dean story. The guys are in Sedona, AZ and Dean gets roofied, basically. Sam takes Dean to eat and they end up having to take it to go because Dean's getting all snuggly and lovey. At first they think it's a sex drug, but it's more affection; and when Sam's in the bathroom, or something, Dean roofies him (as per the instructions of the woman who drugged Dean), and it's Sam who gets the "super lust" hit.

I keep thinking the title is "Dioscuri", but I'm not completely sure. I know it's not the ficlet memphis86 did.

So, anyone?

ETA: Found! Down in comments, if anyone else wants to read it :)
