I strongly disagree with entry #1. Cunnilicious is like bootylicious. It's an observation and compliment of the female anatomy. Only pertaining to the, well, you know, her little girl-friend.
The proper term for the sexual act commonly known as the "69", combining cunnilingus (licking vagina) with fellatio (sucking penis)....together they create the magical cunnilatio.
The pinnacle of sexual pleasure, achieved by a hermaphrodite giving themself oral sex. It is said to be toturous to try to last more than 30 seconds without ejaculating in your own mouth while doing this technique.
