One shot, Snarry Beltane or Walpurgis

[rhiandra]

I've spent two different nights searching for a snarry one shot dealing with a ritual that I believe was based on Beltane or similar holiday. I believe it was established Snarry but dark. Harry was given a potion of some sort and wrapped in ribbons. Snape took him infront of others, one being Draco. Then it seemed Harry's pleasure changed to discomfort or even pain, and then a dubcon as Harry was given to those in attendance with Draco being first. Ends with Snape thinking Harry will understand or some such. Any ideas? Thanks!
