This practice is for people/submissives who love to be tickled for hours on end while often being tied up. It is true that tickling is pleasant but if the torture is taken to the extreme with intensity in the movement of the nails in a repeated manner, it can create a very unpleasant sensation.

Another way to increase the intensity of the torture is to use massage oil to increase the sensitivity of the soles of the feet and also other tools such as a hairbrush for example.

In addition to the feet, the toes can also be tied with rubber bands so that the victim cannot move at all, forcing him to endure the tickling.
