Consensual tickling

Consensual tickling or tickling fetish refers to any instance of tickling in which the party being tickled has given consent to the party providing the tickling to do so. Some people find tickling to be an erotic experience. They may prefer to be the dominant (tickling) party or the submissive (tickled) party, or they may enjoy both. The people in these roles are often referred to as the "tickler" and the "ticklee" respectively. Some people may prefer to be tickled in specific areas, usually erogenous zones or other particularly sensitive areas of the skin.

Methods
A tickle session usually begins with one submissive partner allowing the other to tie them up or restrain them in a position that exposes bare parts of the body, particularly those that are sensitive to tickling. It is commonly associated with the tickling of the bare feet or armpits though many parts of the human body are also deemed ticklish like the sides of the torso, neck, knee, midriff, thighs, navel, and the ribs. For this reason the submissive may be tied in a position that exposes their whole body for the tickler to access and would typically be in their underwear or partially to fully naked. The latter could also be intended as a form of humiliation or exhibitionism for the submissive while being tickled or as visual stimulus for the person doing the tickling.

The bondage methods of the tickling usually follows the same basic methods. The object of the bondage is to render the submissive unable to prevent the tickling, as well as rendering the ticklish areas of the submissive vulnerable. The submissive is usually bound in a sitting or lying position rather than a standing one as to expose the soles of the feet which are often among the most ticklish areas of the body. Other common positions may include over-arm ties, hogties and spread-eagle positions. The restraint of the arms above the head or to the side leaves the upper body and underarms susceptible to the tickling. This enables the tickler to use whichever methods or implements they choose, e.g. fingers, tongue, beard, feathers, brush, pine cones, salt sticks, electric toothbrush or a hairbrush.
