Shayne is 20 years old and from Southern California. Here, she's in Florida, relaxing. Why? Because she runs marathons. Yeah, all 26.2 miles of them, which means two things: 1.) She's in great shape. 2.) She can go the distance. Nope, no five-minute sex sessions for Shayne. She needs a marathon man. But here's the thing we have a hard time believing: After Shayne runs marathons, she says she likes to masturbate in the shower. How does she have the energy? We'll tell you how: She's young. Hot. Horny. Watch the video. You'll see what we're talking about.
