That seems to be one of the many things that tkphiles of all age and geographical locations seem to have in common: I also had and have fantasies about being tickled by non human creaters of all kind.
Usually my fantasies are about an alien, amorphous, asexual (though it always ends up having something feminine) creature, coming from space who kidnap me and brings me with her all around the universe.
The creature belongs to a superior race, is super intelligence, limits of time, space or matter have no effects on it, though in my fantasies I can't really understand what it is, because humans are too limited.
It alters my body so that I am incredibly ticklish and I can live thousends of years, and she abuses of me in every possibile way, of course mostly taking advantage of my enhanced ticklishness, for hundreds of years, since the creature made me able to survive inhuman tortures (again, mostly tickling based).
I can't understand why the creature is tormenting me like that. I can just vaguely perceive that the creature wants to experiment, since it's curious about human, but I can also feel amusement, or the alien correspondent of amusement.
After some hundreds of years, even if time is very relative in this new condition of mine, the creature places me on a planet populated by the most strange plants, animals and sentient creatures, and obviously every of them is obsessed by tickling.
For some other hundreds of years I live unbelievable adventures as a ticklee, captured, enslaved, humiliated and so on by the inhabitants of the planet.
Then I am placed in another continent on the planet where I am considered a semi-god, and I can tickle torture, and generally abuse, whoever I want, for other hundreds of years.
In other fantasies I'm a kind of king, or god-king, in a giant space station, in which an earth environment is been recreated, and the population is formed only by women (only adults between 18 and 50), and 5-10 men.
I'm the only political power and my authority is based on the fact that the population believes I'm a god or something like that, so everything I say is sacred. Every woman on the planet is ultra ticklish and men are not ticklish at all.
The law says that women must wear very scantly dresses (they are practically naked) and only open sandals, they must blindly obey to men, everyone of them is bisexual and love to tickle and to be tickled, even though they would do everything they can to avoid being tickled, since they are too ticklish. Men, of course, love to tickle women and do that all the time, plus abuse of them in every possible manner.
There is a hierarchy between women:
1) guards (only black women) who are strong and trained to weapons - they are socially superior to other women and the other must obey to them (but they are always subdued to men). They can be tickled only by other of their kind or by men, but can tickle every other women.
2) citiziens (every other ethnic groups, except asians): they are the majority and they do all the civil activities and works. They can be tickled by men and guards, but can tickle only other of their kind and asian women.
3) slaves and vestals (only asians): slaves are tickle toys for men and every other woman cathegory, they don't work, they just get tickled, but cannot tickle anyone.
Vestals are my 100 personal slaves: they are vergin and can have sexual pleasure only if I let them (some kind of psichic power), and I use this power to torture them, combined with tickling, humiliation, domination games, and so on.
They are secluded in my mansion, enourmous and totally inaccessible to others than me and my vestals.
About ethnical details of what I wrote above: this is just a fantasy, it's just that I see black women as perfect ticklers and asian women as perfect ticklees, don't ask me why.
Yet another fantasy: women rule the world, men are slaves. They must do all the physical work and, in the spare time, be tickle toys of women, who of course are all tickle freaks 🙂 The women/men ratio is about 1/20. Women are not ticklish at all and men are all incredibly ticklish.
Men must wear almost nothing, but they wear shoes (not to harm their sensitiveness on their feet). Women are trained since very young to torment men, with no particular reason (I love this detail... 😉) Men are often forced to tickle eachother for women's pleasure and, again, undergo every possible kind of abuse.
These are more or less my weirdest recurrent tk fantasies.
