The predisposition to fantasize about engaging in sexual intercourse with the members of one's own immediate family group. i.e. Father, Daughter, Sister, Brother, Mother, Son. This condition is admonished by the general population but is very much alive in the minds of everyday people. At times (probably more often than not) people do enact these fantasies.
