If you're just starting out with role reversal and harness play, the Beginner Strap On system is a great place to begin. This comfortable, basic nylon harness straps on easily and holds the included slim, tapered dildo securely. The dildo itself is perfectly sized for an anal beginner, it's flexible and slender, with lots of give and a curved tip to hit the prostate for maximum pleasure. Although it works well in the harness, you could certainly use it on it's own as well. Harness adjusts to fit most sizes. A blindfolding mask is included.
