The fabled holy grail of porn. Some say it's just a myth, while others say it's a deeply hidden secret buried in the depths of the internet.

The Holy Grail is a term used by porn stars, can be used as a noun, verb and/or adjective, and is basically when a female porn star takes a cock in her arse, a cock in her vagina and a cock in her mouth, all whilst simultanously giving two handjobs.

In my experience, The Holy Grail is a trick best left for the pros.
