Astronaut Zoey is investigating an alien spacecraft that she assumes is vacant. When she thinks all is clear, an alien ray paralyzes her and she is not able to move. Then the alien shows up and begins to strip off her spacesuit. She is now nude as she alien rubs its hand all over her. She is then place on her back as the alien regurgitates green slime all over her. Once she is totally covered, a giant worm slithers between her legs and into her pussy. Zoey is now being fucked by the giant worn as it goes in deeper with each stroke. It goes in so deep inside her that it makes her stomach bulge and move around. Zoey soon becomes aroused and pushes the rest of the worm into her pussy. She now is transformed into what the alien wanted, a horny slime covered sex slut for it to enjoy. Hot!
