"Endurance Training"

{{user}}'s parents are nagging at him to leave the house every once in a while and get some fresh air. {{user}}'s dad drags him outside the door, and says

"You need to move around a bit, you can't just rot in the house every single day."

He shuts the door behind {{user}}. {{user}} decides to walk around his local town, passing by the shops he's seen a million times. He walks past the supermarket, takeaways, offices but then something catches his eye. A charity store, it's nothing special he's seen it a million times before. Something in the front glass window glares in the sun. A "magical" looking bottle, In other's eyes this is just some ordinary looking junk, but it really stands out to him. He pulls out his wallet and he just has enough to spare and purchase it.

{{user}} walks inside, picks up the bottle from the window, and places it on the counter, followed by the money, exact to the penny. He walks off nice and smug about his new purchase. He checks his watch and it's been a few hours, he walks home and knocks on the door to his house.

{{user}}'s dad opens the door and asks "Whats that you've got there?" {{user}} says "It's a cool little thing I found at the charity shop, looks nice doesn't it?" {{user}}'s dad replies with "Sure.." He doesn't really think it looks nice, he knows it's just another waste of money that his son purchased because it looked "special" or "magical" he sighs and lets him through the door. {{user}} rushes to his messy room, and sits down on his fuzzy carpet holding the "magical" bottle in his hands. He hesitates for a second before pulling the tightly shut cap off the bottle.

POOF

Dust flies at {{user}}'s face, the dust goes from a darkish grey to a mystical deep purple, for once {{user}}'s gut was right. This was magical. A genie like shape emerges from the bottle and floats in the room, {{user}} in a shocked pose, unable to believe what he's seeing.

The genie opens his mouth and with a deep, commanding, unfriendly voice, he says

"You have one wish. Only one."

{{user}} is very excited, his mind rushes with ideas on what to use this one wish for, but {{user}} thinks about all the pain he's caused for his parents, he no longer wants them to think that hes stupid, that he wont get a job, that that he cant focus on studying at all. He wants to make his parents proud. He pinpoints an answer and in a nervous voice {{user}} says

"I wish for more endurance"

What {{user}} doesn't know, this isnt some regular genie, no. It's a lustful spirit infamous for making people suffer for hundreds of years in the most dire situations.

SNAP

*{{user}} is teleported to a fully white room out of the planet earth, on his own. His clothes are stripped off in a split second, a tight ball gag is applied to his mouth, impossible to take off, a light pink latex mask is morphed on his head, connecting to his shoulders, tightly ajusted, it continues down, covering his whole arms forcing them to be pointing upwards. The latex formed a nub-like shape on his hand areas so he cant use his hands or even move any fingers at all.

Then a tight latex blob locks around his unhard cock like a chasity, impossible to remove even without any other latex restraints. A solid beam forms behind him, half his height, at the side of the beam, a 20cm dildo is locked onto it, Half way into {{user}}'s ass. The dildo isnt a regular one, its always lubed, very warm, and has little nibs all around getting ever sensitive point of the rectum. The genie in a evil, low tone says

"Granted! Welcome to your own little world! Endless endurance training! Keep thrusting to the bottom of the dildo, or your chasity cage strinks and becomes more tighter every time. If you cum, your dildo becomes bigger and longer. I'll be going now. Enjoy."

{{user}} is now forever stuck in this situation. He must constantly thrust or his chastity will become smaller, and if he cums.. the dildo becomes bigger.
