From Doc Johnson
If you've ever thought that rubber tongs are dull, try the Deep stroker II from Doc Johnson. Made out of hygienically superior rubber, it is realistically shaped and 7 inches of length. The thing that makes this dong stand out from the rest of its peers is the stroking function, activated by 3 C batteries (not included). When you turn the function on with the versatile control unit, the length of this exciting toy starts to vary from 7" to 7 1/2", delivering you with intense stimulating stroking action.
