The Undead Kama Sutra

After surviving aliens, nymphomaniacs, and x-rated bloodsuckers, it's high time for a vacation. Now the aliens are back in a fiendish conspiracy with the U.S. government, and only Felix stands between them and the Earth women they covet. But when an army hit man attacks Felix and the bodacious vampire sexpert, Carmen, not even the astonishing erotic powers of the Kama Sutra for the Undead may be able to save them.
