A demonstration of a new sex game for the Kinect video game console received more than 11,000 hits on YouTube by Thursday morning -- just 15 hours after it was posted.

The controller-free console designed for family fun became a new medium for pornography less than two months after it was released.

The game allows users to simulate sex acts using the console's advanced technology, which requires users to move their bodies instead of a controller.

"The open-sourcing of device drivers for Kinect have enabled the device to be used directly from connected PCs operating on Windows 7. The Kinect interface provides another exciting interface option for users of the sex-simulation software to control the experience in extraordinary new ways," the game's developer, 3D sex-simulation producer ThriXXX, told cnet.com.

But the company acknowledged that its game might be blocked by Microsoft, Kinect's maker, from using its technology.

"We do not have permission from anyone on any of this stuff and have been using stuff from the hacker community to do a working prototype, following what [is] going on in that world," spokesman Brad Abram said.

More than 2.5 million Kinect consoles have been sold since it was launched Nov. 4.

"This isn’t the first example of a technology being used in ways not intended by its manufacturer, and it won’t be the last," Microsoft told FoxNews.com. "Microsoft did not authorize or license its technology for this use. Xbox is a family friendly games and entertainment console and does not allow Adults Only (AO) content to be certified for use on its platform, and would not condone this type of game for Kinect."
