Deep in space, on an isolated research station, lightyears from any form of civilisation, a horny female astronaut toils away her days. After being visited recently by a formidable futa alien, the Sgt. wonders if she'll return and just how she got past the security systems onboard. She doesn't have to wait long to find out. This time, the dominant alien babe has brought her apprentice with her to fill all the Sgt.'s holes and learn more about the human race. It's not long before he three are fucking wildly - all in the name of science of course!
