tickling
Lightly touching parts of the body to bring about laughter and twitching. Some parts of the body are more ticklish than others and it varies from person to person (feet and the ribs under the armpits are fairly common).
Note that posts that focus on tickling are considered to be fetish content (especially if the character who is being tickled is also bound), and should usually be rated Questionable.
