Casting porn videos feature aspiring pornstars and nude models being interviewed by what they believe to be a XXX casting agent. The interviewer often has a camera running while asking the eager 18+ applicants a series of kinky questions related to their sexual preferences. The potential pornstars proceed to strip, pose, dance, and toy their pussies and asses to prove their desire to appear in adult films. The next step almost always involves the applicant performing a blowjob on the interviewer prior to full-on sex in hopes of landing a job. All of this takes place on a comfy "casting couch".
