A sexual act in which a hole is cut in the centre of a Book of Mormon, after which the book (BoM) is placed on the penis and sexual intercourse commences.
This type of sex can be extremely physically pleasurable for the female, as it ensures the male stimulates the outer regions of the vagina more thoroughly. It can also be psychologically healing for those who have suffered the devastating effects of sexual repression from being raised as a Mormon.
I had some great BoM sex last night!
Shit, don't let the Morg hear about that!
