A sex magick rite involving the oral exchange of the partners’ shared and transmuted sexual fluids. It can be accomplished by sensuously licking and sucking "the First Matter" from the "Retort" and then holding it in the "Mother Eagle" of the male before exchanging it with the "Mother Eagle" of the female who should likewise hold it before ingesting it. Even better is that this last be a long sustained kiss before mutually swallowing the "Quintessence." All the while, the intended goal of the ritual is held in their consciousness.
While "Sixty-Nine" is a not unheard of sexual practice nowadays, it is the extended technique and the attitude and imagination that transform it into the Eucharistic Rite.
