In a dimly lit room, two female scientists examine an alien specimen. Their curiosity is piqued despite the warnings of their superior. Suddenly, the alien releases a parasite that attaches itself to one of the women's necks. She starts to experience intense sensations and becomes increasingly aroused. The parasite communicates telepathically, demanding sexual pleasure from its host. The second woman, intrigued and aroused, begins to explore the infected woman's body. As they engage in a passionate kiss, the parasite takes control of both their minds, compelling them to continue their erotic encounter. Their moans echo throughout the room as they succumb to the alien's desires, becoming willing participants in their own seduction.
