When I was younger I saw a softcore porn on cinemax that had scientist going into space. They brought this green ooze on the ship. One of the hot female scientist was doing tests on the ooze and than the ooze took over her body and than she was naked. She had sex with the captain than all the crew than that person got infected. than the crew came back to earth... so if anyone remembers the name let me know... there was this hot red headed girl in it...

Believe it was part of the emanualle in space series they had on cinemax back then.
