A combination of all of yours pretty much is my fantasy. Mine is to be one of those crazy powerful rich tycoon type people, the kinds with money and connections, and as that obviously comes, corruption.
Now, imagine every friend, coworker, classmate, person on the street even, that you looked at and thought "She'd be fun to tickle." Imagine if you could just DO that.
Say you had the connections to make all of these people disappear. Right into your secluded bunker, hidden somewhere on your estate not listed in the blueprints. A soundproof gigantic prison, with interrogation rooms and cells on cells. Girls are taken there for being your personal toy. You toy with them, strip and tickle them, slowly convincing them that this is their new life, and they should accept it. Nobody is coming to save them. All they're gonna know is tickling for the rest of their lives. And tickled they are, for hours and hours. Tickled until they're crying, screaming, offering themselves to you. And when you take up their offer, you make sure that it's with their legs in the air, biting their heels and tickling their toes, another hand pinching their sides as you fuck them hard, their mind splitting in two between agonizing ticklish hell, and pure pleasure.
When you're finished with your session, they go into The Wall. A cell beyond a wall that cements their permanent stay. It has food, a bed, water, a toilet, etc. But against the bottom part of one of the walls is 3 holes: one their ass to sit against, and two for their feet. When they are requested, they have 2 minutes to get into position within the wall, where they are locked in place. Waist is tightened firm by mechanisms, ankles are latched and toes tied. They will be used and tickled for as long as the session may last, afterwards they are free to do as they please in their cell. And if they don't meet the 2 minute mark, guards will force them into the position, with the added punishment of said guards tickling her upper body at the same time. Of course, they're more than welcome to give her a round in the wall after you're done using her.
They all stay like this, anyone you please, no repercussions. They all simply are your ticklish prisoners to use and tickle as you like.
