For today's Throwback Thursday we are throwing it back to the 1960s with a swingin' sci-fi feature that is filled with sex. Let's check out the sci-fi suck sacks in 1968's Space Thing.

The plot follows a man who likes to read science fiction magazines in bed. One night, his wife seduces him as he is reading so he...falls asleep. He then has a wild and crazy dream filled with aliens and naked women! His dream winds up being an erotic sci-fi fantasy that every man would love to experience.

In his dream, he boards an alien ship to disguise himself from aliens attacking his planet. The captain is a hot woman whose crew is made up of other hot women with whom she has lesbian sex. She also whips them when they try to have sex with and save our leading man.

Cara Peters plays the captain, named Captain Mother, and she is a no-nonsense babe. She spends a lot of the film topless, carrying a whip, and wearing a barely-there thong that really gives her ass a nude illusion. No wonder she is the captain - she has the best rack in the movie!

All of the women basically throw themselves at our leading man. At the end of the film, he forces the spaceship to make a crash landing on an asteroid, and when the ship crashes everyone runs around topless and starts banging each other. So that's basically the plot! It's one man's epic sci-fi sex fantasy.

Karla Conway, Merci Montello, and Bambi Allen all round out this cast of hot women with round mounds. The babes rise above in this film and manage to make us laugh, smile, and get horny. Very very VERY horny.

The story behind this film isn't great. For example, the producer David F. Friedman was worried the actresses would ask him for more money if they became well-known, so he urged all of them to be credited under fake names. This film was written by a mysterious writer named Cosmo Politan - seriously. This is their only writing credit, so it's hard to say who Cosmo Politan was in real life. Fake names all around!

Why don't we know more about this science fiction sexploitation flick? It's hard to save. It could have something to do with the producer suppressing everyone else in the movie so that no one could become a household name. Or it may just be the way with a lot of low-budget exploitation films from that era. Either way, this is a goofy, sexy romp.
