In addition, sources told RadarOnline that sexual toys are used in the footage -- which also includes the former The Girls Next Door star having intimate relations with multiple partners.
"This is really, really graphic and showing her in compromising positions; things you would think would be embarrassing for her," a source told RadarOnline.
Earlier this month, Vivid Entertainment announced its plans to releaseKendra Exposed -- a sex tape Wilkinson made several years ago -- on May 28.
Justin Frye -- Wilkinson's ex-boyfriend who sold Kendra Exposed to Vivid and stars alongside her in it -- is involved with the video that recently emerged, according to RadarOnline, which added Vivid is also in possession of the new footage.
Similar to the footage with Frye, Wilkinson made the tape with Taryn before she moved into the Playboy Mansion as one of Hugh Hefner's girlfriends in 2005, according to RadarOnline.
