We're not usually big on new-age self-improvement schemes, but Yoga teacher Lindsey Grant has us thinking there might be something good going on in that camp. Lindsey spreads her strong, lovely legs wide for our custom metal device, leaving her pink snatch open for the kind of exercises we usually prefer: flogger, dick and vibe. We clamp her nipples, rubber band her feet, and watch as this very composed young woman focuses her strength and flexibility on a more earthly vibration: nonstop orgasms.
