www.xbiz.com is reporting that authorities have busted an operation in Svishtov, Bulgaria in which live sex sessions were allegedly filmed for an unidentified U.S. adult website.

Bulgarian couples were allegedly paid roughly $366 — to appear on camera.

According to the story, the operation recruited nearly 30 amateur performers between 18 and 20 years old.

Not too long along police in Plovdiv, Bulgaria uncovered two studios that were producing pornographic movies.

Two men were arrested during that raid. And that operation was suspected of hiring young women and teenage girls and boys as strippers.

The strippers included three under-age girls and over 20 adult women, who worked eight hours a day for about BGN 300 per week. Users paid USD 6 per hour to access the web sites.

Both studios were believed to have operated for about five months prior to the raid. Footage shot at these studios was posted on pre-paid web sites maintained by US-registered Internet providers.

Police seized cameras, computers and various toys as well as arms and ammunition.
