I put some TENS pads on Candy’s thigh and just connect her to a simple TENS unit. That means I can make her leg muscles contract, with frequency and degree controlled by a little box. I like the big complicated power units, but it’s amazing what you can do with just a pair of simple dials. Then I shift the pads to the juncture of her pubic mound and inner thighs, for control of some different muscles.
