Spencer Pratt has unearthed a very long girl-on-girl sex tape with Heidi Montag and Playboy Playmate superstar Karissa Shannon, so now there is a Heidi Montag sex tape video and a Karissa Shannon sex tape film that kicks butt.

According to verified sources Spencer was at the Malibu house he once upon a time shared with Heidi and Karissa and this is where Spencer came upon a camera with sex video of Heidi and Karissa going at it like wild bunnies. Spencer quickly decided he could make a mint selling his newly found videos, so he recorded them to DVD discs and visited several adult studios including the big dogs Vivid and Playboy.

The videos feature Heidi and Karissa in a full blown lesbian sex session including plenty of dildos, vibrators and fingers with no men allowed. Darnit! We must say that we have never seen a full lesbian sex tape video with two of the hottest chicks on the planet, but damn, this has got to be one of the best celebrity adult videos on the planet!

Calls to Spencer, Heidi and Karrisa’s reps have been returned and confirmed the videos are real: “We are aware of the videos and yes they are real, we are working on the details at this time and making sure no one gets screwed.” LOL!!!!
