Six Eighty-nining 

A form of analingis that occurs between two partners, in which both partners lick each other's anuses.

basically, it's like 69ing, but with buttonholes-- a double rim job.

My girlfriend was giving me a rim job and wanted one too, so to make it fair, we started Six Eighty-nining.
