Prolog:
The year was 2100. Two hundred years had passed since the change. Astronomers noticed instantly. All of the stars changed, none of the other planets were there only the sun, the earth and its moon seemed the same. The next thing that was noticed was the two other Earths and moons each one third the distance around their solar orbits, all three equally distanced from each other.
The twentieth century these three worlds experienced was vastly different than the one we know. By 1945 all three Earths had established contact. The knowledge had prevented the World Wars and limited the starting knowledge of rocketry, delaying the space programs by a couple of decades, though by the mid 70's all three Earths had satellites in orbit. All of the worlds established global governments and ended war on the individual planets. Each Earth was determined to make it to space and to the other Earths.
This is where the similarities end.
One Earth was led by the United States of America. This world would come to be known as Amearth. Over the years it developed a sense of unity and equality between all persons. This led to much debate and many uprisings. The many voices drown out the need for action and Amearth fell behind in development as the others surged ahead. They didn't reach their moon until 2001.
Another Earth was led by the Japanese, Rising-Earth. The fierce determination and class structure of their world order caused them to develop at a fast rate. They landed on their moon by 1980 and had six space stations by 2005.
The last word was ruled by Russia. Mother-Earth didn't get a satellite up until 1976, two years after Amearth, but they were on their own moon three years later, months before Rising-Earth. The delay was caused by a brief uprising in the late '60s, where all of the men in power were executed and replaced by women.
In 2037 all three Earths created a space station near the orbit that would have been Venus, to meet and trade, but little ground has been made as no Earth trusts the other.
Rising-Earth is distrusted for its treatment of women.
Mother-Earth is distrusted for its treatment of men.
Amearth is seen as weak by the other two, and a great place to gather slaves and resources.
All three now have great technology and power. All three want to be the only Earth.
Episode 1
Don and Puja walked down the Paris street together, if together meant Don was following two feet behind on a leash. He was wearing nothing but a collar, eye-tracking glasses, and mechanical chastity briefs.
Mother-Earth Paris had some strict laws even for Mother-Earth. If his eyes lingered on a woman too long his genitals were shocked or squeezed by the chastity device. Don found himself either looking up or at Puja the whole walk.
As his "mistress" the device didn't punish him for looking at her, only for letting his eyes linger on the scantily, or often unclad, women around them. So he stared at Puja's ass in the bikini bottoms.
How had he not noticed her ass before? It wasn't like he hadn't seen his partner nude before. Hell, it was part of their training together to spend a month locked in a room with no clothes. They slept in the same bed, buck naked, and her butt never had his attention as it did now.
Brown and firm, it swished as she walked. All Don could think about was cupping it as he lifted her up and onto...
"Owe..." he said under his breath as a jolt of electricity ran the length of his penis, causing him to stumble.
Puja barely glanced over her bare shoulder as she pulled him along, "knock it off," she whispered.
"I thought I was allowed to look at you," a woman walking by glanced at him, "mistress," he added.
Puja turned to face him. Don's eyes instantly darted to the two small perky breasts that had nothing to obscure them besides two black nipple covers. The device began to crush his cock and he closed his eyes.
"It doesn't like you being aroused in public," she said grabbing his hair and talking into his ear, "look at my back or hair."
Don gritted his teeth but whispered, "That won't help, mistress," as the clamp released his cock.
"We trained for this," Puja said, "get your shit together!"
The pair stood and walked to the hotel, Don trying not to think about his partner's body.
Puja couldn't believe it. She and Don had been pair together for six years! They had trained together since they graduated high school. They had both seen each other's bodies, fucked each other, tortured other agents together, and even each other for Amearth. Now he's getting uncontrollable wood because his cock is locked in a death cage on a planet that hates cocks?
She shook her head to herself. She really did want to comfort her partner, but that would be out of character. Instead, she led him by the leash to the hotel.
The man who checked them in, or rather, checked her and her pet in wore a bow tie, a name tag pierced to his left nipple, and a glass chastity cage, nothing else. He kept his eyes on the computer in front of him the whole time, refusing to look at Puja.
Puja absently wondered how he would react if she removed the nipple covers or started to fondle his balls. He probably wouldn't respond, at least not to the nipples, he might have to respond to direct touch to appease her as a guest.
