Jeannie Santiago is doing wonders for Playboy as their site's latest amateur cybergirl, but we assure you, she's much more than amateur. Jeannie tells us how she likes to exercise and ride bikes to keep a tight butt, which will not disappoint anyone when she shows it off in the video. This California girl sports black on black with a nice set of heels. If it's your first time riding with Playboy, Jeannie might be just the way to dip your toes in, or you could just go all extreme sports with it and follow all our Mandatory girls.
