(If this has been done before, my apologies as I didn't search. :p )
To set the scene:
A traditional family wedding. In a church. Or not. Regardless though, a proper family wedding. From the crying aunts, fawning grandmothers and twitchy fathers to the receiving line and reception hall. However, the bride is not just a bride, nor the groom just a groom. Instead, Master and his submissive.
Unbeknownst to the guests, there is a whole other world present.
The question:
What BDSM elements would you (or could you) use in this scenario?
Remember, the blubbering aunts, fawning grandmothers, twitchy fathers nor any of the other guests are to sense anything unusual.
