Sex Wars(1985)

Sex Wars, an erotic space odyssey, is the first adult film with major studio sci-fi plus lots of hot, hungry flesh! Princess Layme is just landing on Pluto, in search of a crew to man her spacecraft... for a most dangerous journey, past the solar system, to the far reaches of the galaxy... to the planet Tryos. She finds Brinker Duo and Mark Starkiller and bribes them with money, sex, booze and sex. Baltazar, the evil ruler of Tryos, has populated his planet with sex-slaves, including Princess Orgasma--Princess Layme's sister. The attempted rescue ends in the capture of Brinker, Mark and Princess Layme.
