Many college students responded to the ad looking for participants for a new sex study. Out of hundreds of applicants three were chosen to take the test for admittance. This is the trilogy of the stories of Savannah (The Willing Prisoner), Molly (Another Willing Prisoner) and Evan (The Last Willing Prisoner) and their first experience with alien life forms.
Each experience is unique and their interactions with different alien life forms are erotic in nature and the core to admittance to the sex study.
Warning - as with other Olivia Lawless stories and books, reader discretion is highly advised. This story contains very descriptive depictions of sex between consenting adults and fictional creatures.
