Newcomer Olivia Preston is making her Playboy Plus debut with the help of photographer Cassandra Keyes—the two teamed up for an adrenaline-pumping set in British Columbia’s scenic Selkirk mountain range, and the results will give your heart a serious workout. The all-natural blonde put on her yellow and black short-shorts and a sports bra, hopped on her mountain bike and went for a grueling ride up the mountains. “I have a very womanly body,” explains the athletic Canadian, grabbing her breasts for emphasis. “I have proportionate boobs—I like them a lot—but I really like my hips the most. I have the skinny girl, hourglass curves.” Work up a sweat with Olivia Preston, right here on Playboy Plus.
