CastingCouch-X is the first port of call for amateur Hollywood wannabes trying to break into the porn industry and show off their sexual prowess for the film-maker.

It plays on the "casting couch" theme, which originated in the motion picture industry, where an apprentice employee trades sexual favours to a superior in return for a job or career advancement.

The site was founded in 2012 and has been named among the top 10 porn sites by pornusers.com. Its secondary niches are reality porn and hardcore sex.

The Best Porn, a popular review site for online porn, claims the pros of CastingCouch-X are its exclusive hardcore scenes and high quality videos. According to the reviewer , the collection is not that large as it is still a new site and only has 78 films available.

It has shot to wider fame in recent months, with young college students being outed as porn stars on its site.

Belle Knox, an 18-year-old Duke University student whose real name is Miriam Weeks, was exposed by one of her classmates. She was not concerned, however, and later disclosed she was making porn films to pay her high tuition fees and said "doing pornography fulfils" her.

Alyssa Funke, meanwhile, was a student from Minnesota who used the name 'Stella Ann' on CastingCouch-X. The brunette, who was studying at the University of Wisconsin, appeared to be proud to make her debut as an amateur, even updating her status on Twitter to porn star.

But after classmates from her former school, Stillwater High, found out her secret and taunted her online, she could not handle the criticism and committed suicide. According to KMSP-TV her video remains on the site.
