How I write in the tickling will depend on the story. I have been writing stories since I was a kid. Iam into strong characterizations and personality characteristics, as well as what else is going on in the character's lives, and then I incorporate the tickling in as part of it. I have written stories on here about a tickling bandit who robbed women and then used the tickling to sexually tease and torment them. I wrote another story about a tickling massage therapist who would strike and tie her victims down as they were naked and in a position of having to trust her during a massage, I wrote still other stories of a baseball team on an island who was supposedly a major league team, with one exception, there were both men and women on the team, and they relieved their pressure of being major league baseball players by holding tickling parties after every Saturday night home game.
How you write will depend on what you want to express: If you are into only writing about tickling, then you can just write whatever comes to mind. Some of my stories were random, others part of a series of different stories where other action was involved in the characters lives, so I would revolve the story around the other action, and incorporate the tickling in. For my stories where there was only one story and not a series, I would sit down at the computer and try and figure what the characters were like, and what I wanted them to accomplish or what their goal was in the story. That is my style.
I hope I havent gotten too long here. My best suggestion is to just sit down, and type whatever comes to mind. There is no right or wrong. If you want to write a story where one person tickles or is tickled, go with that, if you want to write one of a tickle orgy and have a lot of ticklers or ticklees, then do that. Have fun with it, and good luck. I look forward to seeing what you come up with.

One other comment: As per the tickling, sometimes I have written the tickling as part of foreplay and as a sexual act in a relationship, other times I did so as part of control, while still others was revenge for an earlier act.
In one of my baseball tickle team stories, called "Basebrawl, Bondage, and forciably tickling the opposition" I wrote a story where the tickling baseball team got into a fight during a baseball game with the San Francisco Giants baseball team, and later that night several female members of the team got into the Giants players hotel room, and tickled them for being involved in the fight.
Those are my views. Good Luck with your stories.
