Day 1
"I really think these two could be the ones," said Pell to his wife.
"Gods know I could do with getting out of this forest and back to the ship. Let's have the drones stop them and see what they're made of," Hera replied.
The two blue-skinned aliens stood deep in one of America's great forests, where they hunted a human couple to take as slaves. Through a neural link, they piloted a silent swarm of tiny drones towards their quarry, stopping the devices when they were a metre above the young husband and wife's heads.
Each drone fired its ray simultaneously, bringing the hikers to a halt, clicking their minds into a receptive, agreeable state. A bio-scan showed the aliens there were no other sentient beings within many miles, and they approached the frozen humans without fear. The drones' calming ray had taken care of any possible resistance, and a little memory wipe could sort out the rest.
"Humans," said Pell, "remove your clothes and packs immediately."
The aliens watched as each human stripped naked in front of them, right there on the forest path beneath the trees. Barely a tremor could be seen in either human's body as they disrobed and exposed themselves to two complete strangers with blue skin. The human's eyes stared glassily ahead, calm and unfocused. They stood beside their packs and felt the warm air on their skin, but could muster few thoughts beyond simple obedience. Pell and Hera smiled icily.
"I'll attach the glasses to them," said Hera.
"Thank you, my wife," said Pell, keeping his distance just in case he might need to intervene.
Hera fixed a pair of black goggles to each human's head, then she stepped back and used her neural computer to activate the programmes. She bombarded each human with computer-generated images of themselves engaging in acts of submission and servitude, then used the drones' bio-scanners to monitor arousal, fear, disgust, and all the other emotions she needed to measure. Each new image added more data, but Hera barely needed it - she had done this hundreds of times.
"The male is erect," said Pell.
"I see that, thank you, husband. Nice cock, too."
"Indeed. I'd love to be the one to lock a cage around it and show him the key."
"Time for that if the wife checks out, husband."
"She's panting and her nipples are hard. Gods, please let this search be over, this primitive planet always gets on my nerves."
"Wait just a minute longer, darling. We have to be sure - don't want to disappoint, now, do we?"
"Wise as ever, my wife," replied Pell.
"And ... oh! They're perfect, both natural submissives and practically crying out to be collared. Shall we take them with us?"
"Please let's. Drones, bind them and sedate them for extraction, then return and take their clothes and packs to the lakeside a mile away. If anyone ever finds them, then it'll simply look like they drowned in cold water - foolish to swim there without knowing the risks. You notice the boy is still erect?"
"He's rock hard, isn't he? Handsome strapping fellow too, reminds me of a slave I used to own before I met you."
"You mean Tymo? You've told me about him before, but I forget. He went on to be...?"
"A pet-slave for the governor's eldest nephew on one of the worlds I used to trade with in the Delta-sector. He - the nephew I mean - sent me a message when the slave finally passed, but he got another thirty years of life out of it."
"Not bad, how long do you think these two will last?"
"They're young and fit, but they might have a hard life ahead of them, and fixing their age appearance really does strain their bodies. Maybe forty years?"
"Forty happy ones, though," said Pell, "at least for their owners."
*******
A few hours later the four of them were back on the cargo ship that Pell and Hera piloted through space. Most of the ship was airless cargo space, but Pell, Hera and their two permanent slaves lived together in a multi-roomed compartment the size of two football fields, with living quarters and a landscaped recreation area that also helped recycle their air.
The two captured humans had been chained up in the middle of a high-tech cell, ten metres across. Its walls formed a smooth cylinder, and the humans were chained back to back, their naked flesh touching. They had been released from the calm ray, and now they writhed and struggled in panic. It was clear to both of them that they were in over their heads. Neither could speak - their voices had been muted through clever nanotechnology.
Pell and Hera had come into the cell with their new captives, to talk them through the procedure they were about to be subjected to. Pell was a tall man for his species and matched the height of the new male slave he had taken, but was much more slender. His kind had evolved beyond the need for brute musculature, relying on drone swarms and nanites to do the heavy-lifting. Nonetheless, he admired the well-built body of the white-skinned, brown-haired male he saw before him.
Pell and Hera were equally pleased with the girl. She had firm breasts and luscious curvy hips and legs that would contrast nicely with Hera's slim frame. The girl had red hair and blue eyes, and a smattering of freckles that fascinated Hera in particular. Pell had slipped a finger into the girl's shaved pussy and found it to be nice and tight, and he thought she had a nice way of wriggling around.
"They're ready for the procedure, my love," said Hera. "Do you want to show them what they'll end up as?"
"I don't see why not. Brawn and Ivory, get in here."
Into the room strode two naked humans. The male was stocky, clearly a bodybuilder, and the same exact height as Pell. He wore a black leather harness around his torso, a black leather collar and a shiny metal cock cage. He looked like he could have torn the slim aliens in two if he wanted to, but upon entering, he dropped to his knees, crawled to them and kissed their feet.
"Good boy, Brawn," said Pell.
"Thank you, Master," said the slave, from the floor.
"Up you get, boy, and let Ivory have her turn."
Ivory was a pale girl with lustrous white hair that fell down her back and seemed to shimmer when it moved. She looked eighteen or nineteen and wore a white collar that appeared almost plastic, and thigh-high boots made of matching material. The girl stood shorter even than Hera, and had a diminutive body that made her look especially vulnerable. She dropped to her knees and kissed both her owners' feet, then stood next to Hera, who held her hand.
Pell addressed the new slaves, "Turn and face us. Watch what you will become. Brawn, attempt violence against me."
A grimace of pain gripped Brawn's face. "I ... cannot ... Master ... the mere thought."
"Order cancelled."
"Thank you, Master," he said, as colour came back to his cheeks.
"Brawn, describe your cock and balls."
"Master, Mistress, this cock and balls belong to you, and you have chosen to cage it in order to display your ownership of it. It has been altered to the size that you prefer, and my balls have been seeded with a device that will deliver shocks to them at a neural command from either of you."
"Good. Brawn, turn and display your brand."
"Yes, Master."
"Describe it."
"It is the symbol of your house, Master and Mistress, which you seared into my flesh with a hot iron in a ceremony when you gave me my collar and my name. It is the same symbol stamped on the cargo crates in the hold, Master."
"Correct, we stamp all our property."
"Brawn, dance erotically. Ship, music."
A beat came clear through the walls of the cell and Brawn took it up expertly. He gyrated on the spot, as the two new human captives looked on in surprise and fear. Brawn used all his knowledge of seduction and display to show off his grace and poise, and it could be seen clear on his face how much he enjoyed what he was doing. His hips bucked and his cock bounced, and he danced with a sensual rhythm.
"Stop, return to my side. Hera, my wife, why not demonstrate with Ivory?"
"Of course. Humans: watch. Ivory, put your hands on your head and stand on one leg."
"Yes, Mistress."
"Ivory, balance."
"Yes, M-"
Smack! Hera's hand shot out and struck Ivory's little bottom on its left cheek, where it scored a stinging blow that brought a tear to the slavegirl's eye. Ivory wobbled on one leg, but she righted herself just in time for the next blow. None watching quite believed she could stay standing after being hit with such force, but she found a way to obey the order. More blows rained down until Ivory's bottom glowed like a forge, and Hera tired of the game.
"Ivory, petgirl."
Ivory dropped to all-fours and then sprang around the circular room, yipping and barking. She jumped up against the naked, chained humans who the show was for. Her hands raked across their bodies like paws, and she sniffed at their backsides and licked their skin. The pale slavegirl cavorted and crawled all round the room, even rubbing her cunt on the new humans' legs for stimulation.
"Good girl, heel."
Ivory remained in petgirl mode. Without an order to the contrary, she would remain there indefinitely - for however many minutes, days or years her owners commanded. She would not speak, would not stand and would not use her hands in any way that a pet could not use its paws. For all intents and purposes, she would leave her human self behind.
