We all need the tools to get off on and this dong is perfect to add to your collection of pleasure toys. This Raging Hard Ons 8 Inch Dong is a great sex accessory from Doc Johnson that is designed exclusively for Vac-U-Lock system strapon harnesses. Made out of firm rubber, this dong is shaped and colored like a real cock. On top of that, the thick-veined texture will deliver increased stimulation to the receiver during the play. So use it with or without the strap on harness.
