Perfect for first-timers Vibrating Plush Harness is made with a soft neoprene backside that prevents chafing and feels great against your skin. The durable 4-way adjustable nylon straps feature easy plastic slides for the perfect fit on waists up to 44-inches and thighs up to 40-inches. The low-rise fit is super comfortable while the four secure the O-ring and hold everything in place even when the action heats up. Three included silicone O-rings allow you to interchange a range of dildos with a diameter up to 2-inches. Spot clean or handwash and lay flat to dry.
