The Dual Pleasure Strap-On Harness not only let's a woman give her partner the pounding of a lifetime, but she can also enjoy some stimulation of her own, thanks to the included, attached plug inside of the harness. The plug can be positioned to pleasure her vaginally or anally. The plug has a 3-Speed remote. The harness can fit women up to Size 16. The plug measures 3" in total length and 1.5" in diameter. The dildo measures 6.5" in total length and 1.5" in diameter. The dildo and the plug are made of rubber material. 3 AA batteries (not included) are required to power the vibration feature. Even without the vibration it could be used as a standard strap-on harness with dildo.
