"Kendra has sex in the video with Taryn Ryan," a source close to the situation told RadarOnline.com exclusively. "They were friends and were hanging out together, with their boyfriends. It's a long tape, about 45 minutes. And there is nothing left to the imagination."

"Kendra and Taryn started fooling around and then Kendra wanted the light turned off. But the camera that was recording them had night vision, so it looks like the Paris Hilton porn tape. Everything is completely clear. The girls are laughing at first, and the guys are encouraging them to kiss each other. They started kissing while giggling and then things got hotter."
