Karissa Shannon's "kinky" and "extreme" sex tape with boyfriend and Smallville actor Sam Jones III is being released on September 28th.

The tape features the former Girls Next Door star and her BF having sex in a moving car, their home and a Hawaiian hotel room. As X17online first reported, the footage features the two in various S&M scenarios, bondage ... and Jones in a spiked collar using a whip on his Playboy playmate girlfriend.

Steven Hirsch, Vivid CEO, had this to say about the 2-hour sex tape:

    "Even though Karissa and Sam made this for their own enjoyment, it's shot extremely well and is as provocative as it is sexual. Never has a girl this beautiful been this nasty...she's completely uninhibited with Sam."

Perhaps Karissa Shannon Superstar will make the perfect stocking stuffer.
