The Strap-On Support System with Vacuum is the ideal choice for amazing results. This unique strap-on system features two durable nylon shoulder straps that easily adjust to support the weight of the large hollow dildo, as well as an adjustable nylon waist strap that fits most sizes. A sturdy metal O-ring holds the dildo in place when the action heats up, while the nylon thigh straps adjust easily to keep everything in place. A Velcro strap wraps around the shaft of the dildo for additional support and four straps help secure the metal O-ring around the base of the dildo.
