Lust in Space (2015)

Jazy Berlin wants to win a spot on the NASA's next mission to the Space Shuttle, but she has to work overtime to garner her spot. Little does she know, foreign spies are using mission members to turn the station into a veritable weapon. At first, Jazy doesn't realize she's unwittingly assisting them in their quest, but she eventually turns the tables on them. 

Contrary to what movies like Gravity might portray, there's really not a whole lot to do in space. So what do the astronauts do? Have sex, of course. The ensemble of space cadets spends the majority of this flick ditching their clothes and bumping uglies in zero gravity, making for one sensual shuttle showdown. Brandon Ruckdashel, Daniel Hunter, and Danny Mountain all star in this erotic escapade, showing off their bare buns while getting it on with the women on board. The sex in this movie is truly out of this world.
