The 4.75" x 1.25" Omega Vibrator features a ridged shaft that plays on the urethral sponge, better known as the g-spot. As you insert this toy, it rubs the sensitive glands. You don't need to know about the g-spot, the toy does all the work. All the elements feature a new ergonomic base with a grooved base that holds the thumb and is angled for a uniquely comfortable experience. Omega is a perfect toy for solo or couples play. It also features a removable vibrator that can be easily replaced or upgraded to a multi-speed unit.
