#143 could hear trucks stopping outside in the huge prison courtyard. He and all the prisoners were heading out into the shivering cold for their daily mandatory exercise. #143 could see snowflakes through the glassless bared windows in the hallway. It was so cold. Even the other prisoners were complaining a bit about it. At least they had long armed uniforms and pants and shoes. All #143 was permitted was his hand-towel of a loincloth. He hugged himself as a cold breeze blew past him.
They assembled out by the newly arrived trucks, standing to attention in the small area of the courtyard that had been cleared of snow.
“It's snowing, I'm sure everyone is feeling cold,” a guard opening the trucks said. “Winter coats will be distributed to each one of you now.”
“Thank god,” #143 said to himself. He was sure his face was flush with the cold. They handed out thick orange jackets one at a time. Each marked with the respective prisoner's number. There were so many. “Hurry up. Hurry up. Hurry up. Hurry up.” #143 shifted impatiently from foot to foot as the snow continued to fall around them.
“This one's for you,” a guard said, handing #143 a steel box with his number on it. “Eh?” Everyone else had received thick jackets!? He placed the heavy container on the ground and popped it open. Inside was nothing that looked even remotely warm. Stainless steel rods, pipes and contraptions that looked like they were supposed to fit together somehow. All unforgiving, cold, hard stainless steel. No cloth.
“What's this?” #143 asked in confused dread. A guard patted him on the head with a smile.
“Your custom steel winter coat. Be grateful for it.” The prisoners eagerly pitched in to help #143 put on his new winter coat. Gone was his loin cloth. He'd never thought he'd miss it. In it's place was a stainless steel chastity belt that tucked his penis snuggly between his legs. It was attacked in one single piece a thick and sturdy beam that ran back between his legs up his lower spine. It also entered his ass as a pipe-like butt plug.
Steel pipes that were shaped to run right atop his hips were screwed into place in the thick, main beam that held the chastity belt. A steel collar fit around his neck and looked like it was supposed to attack to the main beam, but the beam didn't go up #143's spine, but instead jutted out behind him at 80 degrees.
“Does the collar attach to the rod?” someone asked.
“They won't reach no matter how you look at it.” #143's fellow prisoners pondered his entrapment like he was a piece of furniture to be assembled.
Frustrated, the guards even came to help, pulling #143 into a contortion, arching his spine backwards.
“Wear the damn thing already!” one guard shouted, clicking it into place against the boy's will. With it attached, #143 was forced to stand in a way that made him present his ass invitingly. They quickly fixed the final tubes also into place.
“Equipment complete!” The steel pipes touch under the armpits and inner thighs, steeling warmth from the body's heat retention zones. The cloak is crewed in place, making removing it impossible. A chastity device is also attached during the whole winter. A steel device is fastened around his head to force his mouth to remain open and panting. His warm breath could be seen in the cold air.
The “cloak” forced #143 to drastically arch his spine backwards and his legs to be at least slightly spread. In place of shoes, a steel device is attached to the ends of his feet that force him to walk on tip toes, lest he want the soles of his feet poked by a sharp prod. It's like high heals, where the heals don't hold you up, just hurt you if you lower your heals from that sharp angle.
#143 wobbled. “Stand still!”
“Lewd hips,” someone says, stoking them.
“Are you inviting me with your ass? You're a bad boy!” #143 can't help but present himself for them. It's part of the cloak's design.
One of the guards attaches a hose to the bace of the main rod, making it look like a tail. They quickly open the valves on the pipes surrounding #143's sensitive regions. High pressure water sprays out from inumerous holes along the pipes all aiming in at the prisoner and across his naked body. Frigid water! It covered him like a sprinkler. He was contorted naked in a steel framework of sprinklers!
#143 cries out as he was covered in icy water. Everyone backs away not to get wet themselves. They laugh at the sight of him falling over gasping and shivering. Before they'd even started his ears had been flush red from the cold. His cheeks and shoulders and feet too. And now he was shivering uncontrollably.
“Water has a very high thermal conductivity,” a guard explains to the onlookers while #143 desperately tries in vain to stop the water or get the device off. “Because of this, it is often used as a coolant in engines. The steel winter coat is actually a robe of ice.”
