Scientist Penny Parker is researching a newly discovered alien parasite when assassin Emiri step-Momato sets out to stop it from taking over humanity. Joshipine step-son, the lab director, arrives and ignores Penny’s warnings, swallowing the parasite and transforming into a sex-craving monster with pale white eyes. She quickly takes control of Penny’s body and mind. When Emiri arrives, it’s too late Penny passes the parasite to her. Soon, Penny devours Joshipine’s pussy, and the three of them indulge in an intense threesome, scissoring and succumbing to the alien parasite’s lust.
