A pet crate.

"We have reinforced pet crates made to transport dangerous animals. Wrapping him in foil wouldn't do much, but those are made of steel and would block any signal in or out. As long as he volunteers to fly in one and you pay a 200$ fee for the use of the crate he will be cleared to fly. We'll even give you some papers for him to do the same on the flight back without having to lose time like we just did today."

K-T couldn't believe that having him travel in a crate in the cargo hold was the only solution. He had really hoped to use the flight to chat with Lily, not only would he miss this but his dream girl would spend 5 hours alone with his aunt, a woman who took a lot of pleasure embarrassing him and would no doubt relate to Lily his various past misadventures.

"K-T, this is our only chance, are you ready to do this for your family? I know it might be uncomfortable, but it's only for the travel, you wouldn't want to miss or make us cancel two weeks of the best time we'll ever have just for this, right ?" asked his mom.

Presenting things like that left him little choice. His parents didn't trust him to stay on his own at home for two weeks, organizing for him to stay somewhere in the little time before the flight would probably be near impossible and with pretty much all of his family going on the trip that meant that someone else might have to stay behind with him. Having someone he just deprived of their dream vacations in charge of him was a good way to spend the next two weeks. And doing something that would prevent everyone from going was unthinkable he would make his entire family, his sister's friends and his crush resent him from wasting this opportunity.

"Alright, I'll do it. I guess I don't really have a choice. Can I have my clothes back now?" he conceded.

"Hmm, since we got you flagged as a potential threat we had to send your clothes to the lab for some tests. It be a close call to get you on board as it is already. I'll give them a call for them to load them on the plane, but I can't guarantee it. Please quickly sign this form and pay the fee so that we get you on board before take-off." she explained, giving him a thick stack of paper handed to her by another agent. His mom was getting her wallet out to pay.

The form for 'chartering transportation of life stock, pet or dangerous animals' was nearly thirty pages long, double sided, covered in almost microscopic legalese script. With things going like they were the absolute worst that could happen would be to have him be stuck naked in a crate at the airport and miss his flight with his family and all his belongings on the plane. Putting his name on the first page, he signed the last one without reading any of it.

"Let's go, we have no time to lose!" he told the TSA officer. His mom had handed a few bills to the officers and all seemed to be in order.

The next part went very fast. K-T had hoped that he would be led through the same door as the woman with his clothes, but he wasn't this lucky. He was dragged along naked in the terminal at a fast pace. In the crowd of faces he was passing through he was pretty sure he could recognize a few people from high school, no doubt going on vacations of their own and after the show he had given everyone during the controls, many phones were out, ready to get pictures or film him.

It took K-T a while to realize that he hadn't even recovered his shoes and was barefoot.
He was pretty sure that he had seen his sister take his backpack from the conveyor belt before getting dragged away.

After a long walk that he would have hoped to be more private, they finally went through a door and in the restricted part of the airport. K-Twas still embarrassingly hard and knew that he would probably stay that way until he came something he was pretty sure he wouldn't be able to do before getting into his crate. Going down a few floors in rough staircases he was then led outside on the tarmac, the hot asphalt painfully reminding him of his condition.

K-T expected to be lead to some sort of warehouse where they handled cargo. Not on the tarmac, in full view of the windows of the terminal and everyone waiting for their flight.

To his dismay, K-T could see his family, waving at him from the window, some of them phone in hand.

A baggage carrier vehicle arrived at high speed, with only a huge steel crate on its trailer.

"Alright sir, please put this collar on and crawl in the crate." said the agent who led him here, handing him a thick black leather collar with a small lock on it. There was a clear plastic part that displayed a QR code on it.

"Why do I have to wear a collar? I know I have to travel in the crate because of the chip, but I am not an animal!"

"It's regulations. Everything travelling in a crate like this has to be properly identified. If you don't want the collar we have a piercing gun and a bag of cattle tags, it's your choice. It was clearly stated in the forms that you signed."

K-T didn't read what he signed, he couldn't risk missing the flight because he was reading something like this. He put on the collar, not wanting to have a piercing gun near his ears or any other part of him.

He climbed in the crate, it was very dark inside, the thing wouldn't be airtight once closed but only had a series of very little holes for airflow. It was a bit awkward, especially knowing what he show he was giving for those behind him in the airport, His naked ass, dangling balls and hard cock were shortly in full view, It was impossible to cover while climbing inside.

Once in he sat down, his back turned to the opening, in the way that would afford him the most cover. The crate had looked big from the outside, but he soon realized that it was in fact rather small inside. The walls were not just plates of steel, there was a thick layer of insulation before it being covered by more steel. He could sit in it, with his head slightly down and he could probably turn around, but he would probably feel really confined in this.

"Please put your hands behind your back." he was instructed.

Before thinking he did as asked, only to feel a pair of leather padded handcuffs being locked around his wrists.

"What are you doing?"

"Non sedated animals transported in crates have to be restrained for their own safety during the flight. Now please turn around."

"What? How? My hands are cuffed! And Why?"

"Listen, you agreed to all of this when you signed the form, if you don't fulfill the requirements to be transported in a crate you will have to be sent to the quarantine area where pets wait for their owners until your parents go back from vacation. So, turn around so I can do my job and properly restrain you. I have other things to do."

K-T awkwardly contorted himself and after a struggle he managed to turn around, his cuffed arms and back now resting against the back of the crate. His legs were now facing the opening and his position was making it hard to hide his throbbing cock. Even harder when the officer grabbed his ankles, put a padded cuff on each and clipped them on rings near the corners of the crate. His legs were now kept open, K-T realized that he now had no way to deal with his erection during the flight, he would have to wait for the landing or hope that it would unlikely go down on itself.

The agent closed the door of the crate, which wasn't, like K-T had hoped, like the other part of it. It was a panel of very thin steel wire mesh. It was secure and would stop the signal from his chip, but K-T could easily see through and he imagined that everyone could still see inside of it.

"There, all set. You're now ready for travel. Mike here will load you on-board once the rest of the cargo is loaded. Have a nice flight and a great vacation." said the officer before leaving.

K-T tried to say something, but he received a short jolt of electricity from the collar when he did so. It would make sense that they wouldn't want a dog barking for the whole flight, but once again, K-T wasn't a dog or a pet...

K-T closed his eyes, losing himself in the hope that if he couldn't see it he could forget that he would stay facing the terminal windows, proudly presenting his dick until everyone would have boarded.

He only hoped that nothing would stop him getting on the plane now, because his worst case scenario had greatly worsened.
