This is short for the English term Cock and Ball Torture and tanslated into Dutch it means Penis en Ballen marteling. Sorry ladies but this can only be done to men.
A few examples I very much like to do are; tying off your cock and balls, put on nasty clamps, hang weights on your balls and even electro games. Let your fantasy roam free on these waves and if you do not know what it is that runs through you, the answer is “current”
