I Love TENS
From here:
I love TENS, go from pleasure to pain and back again with just a twist of a knob.
Had her climbing the pole several times and begging me to stop, though she still needs to work on the “thank you Sir” after each intense burst. And, she’s decided that the TENS can hurt a lot more then my cattle prod.
Poor dear did learn how not to move away from the prod, and to properly ask me to stop.
So all in all a good night.
