The hard casing is designed to look like a flashlight and it covers a realistic skin like insert designed with four spiraled chambers that will more than please. The stroker can be placed between cushions, mattresses, pillows and anywhere else you could consider a good idea. The insert can be taken out and cleaned and put right back into the hard flashlight shaped casing. Suction inside can be varied thanks to a simple twist of the end cap. With a little warm water or some of your favorite lubricant you can create a life like feel that will definitely amaze you.
