texas, I have engaged in cyber tickling in the past, and it can be fun, especially if done with a partner who one finds enjoyable.
Sometimes, it is conducted in the following manner. The cyber tickler and cyber ticklee might agree on a cyber scene, say, tickling bandit, or dominant husband/submissive wife, whatever. I've done the tickling bandit more often than not. What might happen is the tickler and ticklee might go through a scene, where say, I, as the bandit, would break into the girl's house, and then tie her down, rob her, and tickle her. Many times the ticklee, as they are being tickled, will type capital letters something like HEHEHEHEHEHEHEHEHEHEHE! To denote the laughter. It usually carries on until the ticklee says a pre agreed upon safeword, sometimes RED, or something else, at which point protocol is that the tickler has to stop, and "untie" the lee, and the scene thus ends.
Hope that explains it. I havent cybered in a long time, but I used to often in my first few years of TMF, and had a lot of fun with it.
