A thrusting grinding vibrator! This ride-on vibrator has a thrusting mini-shaft: Sit on top the Lust Dual Rider Thrust & Grind and grind on the clitoral vibrating motor, as the thrust-rod penetrates automatically. Three steady thrust functions move up and down, as the vibration amps the stimulation. 12 functions of vibration + 12 total thrust functions (3 steady, 9 rhythms) are independently controllable: The remote control lets you change each motor's functions separately. The remote's "X" controls the thrusting, as the remote's "O" controls Thrust & Grind's thrusting pulses. This humpable vibrator delivers short, focused thrusts; plus vibration for vaginal and clitoral stimulation (the vibration is focused in the clitoral grind pad outside, and travels into the thrusting shaft too). This Dual Rider is made for everyone who wants more internal stimulation and vaginal thrusting.  To use: Be sure to apply a good amount of water-based or hybrid lubricant to the thrusting rod to avoid irritation, as the silicone folds move back and forth. Waterproof submersible, the Lust Remote Control Dual Rider is easy to clean. Its silicone grind pad is textured with smooth ripples for added clitoral stimulation. It features 55 to 100 minutes of playtime per charge (on high vs. low speeds, respectively); and is backed by CalExotics' 1-year warranty.  To use the Dual Rider: Press the power button on the bottom of the base for 3 seconds, to unlock its travel lock function. Then sit atop Dual Rider! Turn on the remote for easier vibration function changes, or choose to press the 2 built-in buttons directly. Each button will cycle through 12 functions (3 steady speeds, 9 patterned vibration rhythms). This thrusting vibrator is perfect for easy ride-on stimulation.  Grinding vibrator with thrusting shaft Dual stimulation: vaginal & clitoral Thrusting shaft moves up and down 2 strong motors are independently controlled Remote control for easy speed changes Smooth silicone Great for dual stimulation with thrust Travel lock function 55 to 100 minutes play per charge Waterproof USB rechargeable (vibe pad + remote) Dimensions: 3.5 inch shaft length × 1 inch shaft width; 6.75 inches length x 5 inches width
