This is being written as a fill for the Glee Kink Meme prompt.

Warnings: Please read the warnings before reading the story. This is a mind-control/body swap types story where Sebastian pays to have a sexual adventure by entering another real person's body where he can control them like a puppet. When he finds out it's Kurt, at first he wants his money back, but then realizes he can use this to have sex with Blaine and to humiliate Kurt. Kurt isn't aware while Sebastian is in control, but Sebastian likes to leave him right in the middle of humiliating situations and then Kurt can remember everything he did, but doesn't understand why. There will be multiple partners and a lot of kinks. Additional warnings will be listed as needed for future chapters.

Sebastian walks through the glass French doors and into the tasteful and understated, yet clearly expensively furnished and decorated offices of Seikley Enterprises. A middle-aged man with brown hair, a rounded face, and bright eyes emerges from the hallway with his hand outstretched.

"Welcome, Mr. Smythe. We've been expecting you," he says in a booming voice while pumping Sebastian's hand vigorously. "I'm Sid Johnson. I'll just walk you through the process and answer any questions you may have. I'm sure you're anxious to get started with your adventure."

Sebastian answers with a quick nod and follows Sid down the hallway and past several open arches leading to small meeting rooms with conference tables, each surrounded by doors Sebastian assumes lead to employee offices. Sid leads them into a room with a highly polished mahogany desk and gestures to the plush chair in front of the desk. Sid walks around the side of desk to a bar and asks, "Would you care for a drink?"

"I'll have a scotch, thanks," Sebastian replies.

Sebastian sips the brown liquid as Sid settles behind the desk. "You know, I was expecting you to be much older. The majority of our clients are closer to retirement age as our service requires both disposable income and plenty of vacation time."

Sebastian smirks and replies in a bored tone, "Yes, well I happen to have plenty of both. I finished all my class credits to graduate from Dalton in December and I have my early acceptance at Stanford, so I have some time to kill. I've already lived in Europe and visited most of the places worth seeing around the world. A few of my friends have bragged about going up in a space shuttle, but I wanted to spend this time having a truly unique experience."

Sid smiles and says, "Well, you certainly will get that here."

Sebastian sips his drink, rolling it around in his mouth and savoring the flavor. "I'm sure you've seen all the paperwork I had to fill out to get this appointment, so you already know I'm eighteen. I'm actually surprised you gave me the scotch without so much as a raised eyebrow."

Sid's smile grows wider as he replies, "Providing a small taste of alcohol to a minor is hardly the most ethically ambiguous aspect of this transaction. But you already know that. Shall we review the basics of how our adventures work?"

"By all means," Sebastian replies.

Sid continues, "You signed up for our unlimited six month package. This gives you a choice to enter and leave your host as often as you want and to stay within the host as often as you want for that time period. Our suggestion is that you pace yourself, as it takes some getting used to. We recommend a first visit of a few hours, followed by a break of a day or two. The second visit can be a few more hours, the next a day or two, etc. With a few weeks of this conditioning, you should then be able to stay for periods of any length you choose."

Sebastian arches a brow and asks, "What if this 'host' is boring? Am I able to switch to a new one? Or get a refund?"

"That's a common question," responds Sid. "As I am sure you are aware, this technology is new. I can fully guarantee your safety, your ability to enter and leave the host at will, and your ability to completely control the host while you are inside him or her. However, we are not yet able to allow you to choose exactly who your host will be. However there are some ways to influence the category of host you enter."

"I need a little more to go on than that," Sebastian huffs when Sid falls silent for a few moments. "What do you mean by 'influencing the category' of host? I thought I could pick someone I already know?"

"It will be someone you already know, but I wouldn't say that you get to pick exactly," Sid starts. He sees Sebastian's brow furrow and he rushes on. "This is the most exciting part of the adventure. You control the host once you're in there, but exactly who that host will be is a surprise. It will be someone you already know because part of the technology relies upon your own mental images during the preparation process. The scanner will discard anyone you haven't at least had some conversation or interaction with, even if you don't really remember that person in your conscious mind. However, we need to be careful as hijacking another person's body and life, however temporarily, is not strictly legal. Therefore, we blacklist members of your family, close friends, and others you know very well so that if there ever were an investigation, you will not be implicated. There is little fear of this, anyway, as this is such new technology that the general public doesn't even know it exists. Your host will be completely unaware during the time you are in control. When you leave them, they will remember the time when you were in control. Even if something seems odd to them about their own behavior in those memories, they would hardly suspect that they are being inhabited by another person and no doctor they spoke with would suggest it."

Sid pauses briefly to take a sip of water, then continues, "You asked about influencing the category of host. We will ask you to think about what you most want to accomplish during your time within the host and you also can think about broad physical traits that you prefer, such as male or female, tall or short, etc. Your subconscious mind will supply the people you know who fit those categories. Our scanner will filter out anyone on the blacklist and will find the most receptive host for you of the people who remain."

"Okay. So let's go back to my first question. What if he's boring?" Sebastian asked.

"We have found to date that the client's subconscious does a superb job supplying potential hosts for our scanners that will keep the client highly entertained," Sid says playfully, leaning slightly across the desk toward Sebastian. After a moment, sensing no response, he leans back and becomes more serious again. "You won't know who the host is until you have entered him or her for the first time. While you are in control you can look in the mirror, look at identification, or whatever you need to do to find out who it is. You can leave at any time and return at any time. You will not be able to change hosts. If you are unsatisfied after trying at least two sessions with the host, we will refund your money in full, minus the initial membership fee."

Sebastian mulls over this information in silence for a moment. Sid thinks about their conversation and realizes the best way to complete this sale. "I can tell that you are a man who isn't satisfied with the idea of an everyday, humdrum 'adventure of a lifetime'. After all, anyone can travel to Europe, see the seven wonders of the world, or even take a trip into outer space if you have the time and money. And as time goes on, the price of each of these things will come down until everyone in the city is able to do them. But here at Seikley Enterprises, we can promise you an adventure that only a very few will ever have. The more people who do this, the more expensive and exclusive it will become because we need to protect ourselves, our investors, and our clients from any consequences that might come if too many people knew about this technology or this side of our business. In fact, by the time your peers have the time and money to do this, the opportunity will be long gone. But you won't miss out on this adventure, will you?"

A slow, reluctant grin spreads across Sebastian's face. "You're good," he says. "Where do you need me to sign?"
