A year after their encounter with the sex-changing aliens, ballet dancer Lisa and her best friend, exotic dancer Lana, are looking for more sexual adventure. They find it when the aliens return causing impulsive horniness everywhere they go, but this time crashing after a run-in with the human military. But that doesn't stop the young sex-hungry girls from getting what they need. Joined by the petite, voluptuous stewardess Jenn, and their friend Travis, Lisa and Lana have a time licking, thrusting, and swapping sex organs. But the aliens have an even more pleasurable surprise in store for Lisa! If you liked the gender-bending alien orgy adventure of SEXCHANGER, Invasion of the Sexchangers is just what you need to get off a second time.
