our_bbcsherlock | Looking for a NC-17 Sherlock/John fic

I'm looking for a Sherlock/John fic that involves lots of sex and a handfasting ceremony. I don't remember how it starts exactly, but it's definitely porn.

Sherlock and John have sex (I think it might be for the first time, but I'm not sure). I remember Sherlock kept experimenting with John's senses (touch, smell, taste, etc) in a sexual manner so John would have a powerful orgasm. During the sex (or rather near the end), Sherlock and John have a handfasting ceremony (which involved a white blindfold or handkerchief). Sherlock explains to John what a handfasting is and that they're married for a year.

I believe the author had notes at the end of the story explaining what a handfasting was or the origins of it, etc.

Does anyone recognize this fic?
