For some reason this perverted scenario keeps popping into my head from time to time. A man and woman who turn out to be sexual soul mates are getting married. They invite their closest group of friends and family for the wedding: those that share their interests. They manage to find someone licenced to wed people. They get married in wanton get up. As the crowd is watching them make their vows, the soon to be husband and wife are dressed in ways normally unbefitting a wedding. She in virginal white lingerie. Garters, stockings, cupless bra and crotchless panties. He in tuxedo except it is crotchless so his cock and balls are hanging out.

 They are not only made to make vows of love, but vows of lust as well. 

The minister ends up saying: "You may now fuck the bride." And that's what happens.

As the crowd watches in smiles, the bride and groom start by frenching, groping. Move onto cock sucking and cunt eating, and some mutual ass eating. Then they fuck right there on the altar in various positions. 

Finally the groom fucks the brides ass until he creampies it and it drips to the floor. This becomes the wedding tradition for this group of friends and family. In the crowd are among others parents, siblings, aunts and uncles. The after party is not simply one of dancing and boozing but of a big orgy where instead of getting a dance with the bride, everyone gets to fuck the bride. Because the groom fucked her first, right on the altar, the "problem" of his getting to fuck her first is out of the way.
