More control and now it VIBRATES! Designed by a woman, the Feeldoe? started by taking a woman?s body and building a toy around it?the Feeldoe works with the anatomy not despite it. It was designed and created so that you get all the feelings of fullness, holding it comfortably by the neck with your pc muscle (getting a workout at the same time) and none of the discomfort. The saddle goes up to the mons and then extends out at a wonderful natural angle and there are ridges for the drivers own clitoral stimulation. A bullet vibrator fits into a pocket in behind the so the vibrations are centered right where it counts. It?s patented because it?s completely unique and it?s only made by Tantus Silicone. And what a handle that bulb makes; you don?t have to be a contortionist for self stimulation. Feeldoe Slim? features a removable vibrator and is made of a harder material for more driving control. Shaft 1 1/3" x 6", bulb 1 ?" x 3 1/2"
