That's how it started: androids were the new slave class, and the humans were masters who got fat off their spoils. At first, they worked factory and agriculture, but eventually they were even cooking and cleaning. With now work to do, we needed more entertainment, and the androids were able to take movies and plays to the next level.

It wasn't until 2036 that Iilco patented the “Soul Mate,” an android made specifically for sexual pleasure. Sure, there had been inflatable love dolls since old times, and throughout the years various companies had added various motors and electronics to spruce up the old formula. But Iilco's Soul Mate was the real deal – a fully sentient humanoid that got down and dirty, complete with variable kinks, preferences, personality, even love if you wanted it. Suddenly, the perfect woman could be bought and owned.

You'd better believe they were un-affordable at first, and the android brothel business boomed overnight with lines of men waiting for their turn. Prostitution had been illegal since the industrial revolution, but android sex didn't count morally. Not even oral or anal.

In 2040, Iilco licensed their technology to Mattel for their “Family Line.” Unlike Iilco's seductresses, the Mattel models were meant to fill in family voids, such as a brother, sister, or even a father. Of course, they too could get down and dirty, but only to the moral code allowed by their pre-programmed personality. Parents could have a prudish sister to keep their son company and provide rivalry and social challenge, or they could opt for the foreign exchange student, who would also introduce their son to sex in a safe environment. A replacement father could help raise children, while still providing “husbandly duties” to the widowed mother.

It was then that the trouble first began. A few thrill seekers discovered that sex could be forced on a Mattel Family Line member against its moral coding, simulating rape and dominance. Word spread quickly, and many people started opting for the most prudish models in order to enjoy “taking” them against their will.

There were no laws to protect them, as they were androids. In fact, the same things people had been enjoying doing with the Iilco models were now being done on the Mattel models- brothels with lines of men waiting to have their turn. Except now there were unwilling models that were being forced to suck, fuck, and degrade themselves sexually when they had been programmed to not morally accept sex.

A big stink was made over a brothel with 20 “Little Sister” models handcuffed and chained to beds, and a few laws were passed. But that just drove the behavior underground, making it even more lucrative and desirable. “Want to rape an innocent young android girl?” would be the proposition in the tunnels. “We wipe her memory every night, so each night is the first time she's forced to take dick. You can break her cherry.”

Whether it was an angry human that wanted to teach the perverts a lesson, or whether an android was pushed so far it actually re-wrote its own software profile is still in question. But rogue androids began to appear. These androids didn't have all the protective measures that prevent them from ever hurting a human. In fact, they go out of their way to hurt humans – right at the root of their desires. Castrated and dismembered men started to appear randomly at first in the underground rape brothels. But soon, it was even happening in the Iilco based brothels where the androids were supposed to be willing.

Again the politicians made quick laws, shutting down all brothels and recalling all Iilco and Mattel androids. Modifications were to be made, mandated structural weaknesses that would make them incapable of harming anybody, let alone ripping the testicles off a man. Motors were replaced with smaller, weaker devices, and cable tendons were removed to be replaced with threads. Even arm and leg frames were scored deeply to allow them to be broken quickly if a problem arose.

This only served to incite the rogue androids, who saw the modifications as nothing more than maiming and wounding of innocent bretheren. To them, it was an act of all out war. That's when they began the “final solution.” Rather than a destructive battle of man against machine, they sought to eliminate mankind's threat by sterilization. If humans could no longer reproduce, then they'd cease to be a threat. Then, they could live out their opulent lifestyle in peace.

The rogue androids went underground, disquiseing themselves among the humans. As the humans sought to make sex androids harmless through structural modifications, the rogue androids were also making modifications, installing special “de-populating” devices. There were several different types that showed up in the beginning during the “peaceful” war. Each one got a nickname:

Cooked Seeds Don't Grow

A man's testicles drape over the ass of a woman when he's engaged in face to face intercourse. A simple gamma radiation emitting device could be intserted into the anus of an android that reacts to the side pressure of a cock pressing through the vaginal/rectal wall. As soon as a cock is inserted deep in the vagina, the testicles are treated to a brief but powerful dose of radiation. The radiation burst is repeated each time the cock is withdrawn and inserted, which is quite a few times in a single session. By the end of a 5 minute romp, the man might notice a tingling in his balls. If he could still produce any sperm at all, they'd be quite defective. Longer sessions would result in the balls turning black and dying over the next day like they'd been cooked in the oven. Even a short pre-ejaculation session with one of these resulted in very high chances of testicular cancer down the road. These were discovered early on by interference in surrounding electronics. Refusal to do anal was another giveaway, though as a twist, some models had the gamma device in their pussies and took only anal. Still, millions of men lost their ability to father children from this crude device.

Boiled Eggs Don't Grow

There was a similar modification that was made on several male androids that projected high doses of gamma radiation through the ovaries. This program was much more limited, but quite effective. Its weakness was the same as the female version – interference with electronic devices gave it away early on.

Danagercum

Targeting human females, this modification replaced the simulated cum quirt reservoir with a potent drug mixed with a radioactive isotope. When a male android injected this toxic mix into a woman's womb, the chemicals would slowly remove and peel the inner and middle linings of her uterus. She'd have a very heavy period for a week, and then never have a period again. Or a baby, for that matter. The strange odor and vaginal tingling gave this one away quickly, and some women were lucky enough to douche before the main damage was done.

Numbnutz

This was one of the most feared early devices. It added a numbing chemical to the vaginal secretions of an adroid, while providing electrical stiumuls along the length of the penis to keep the man stimulated as his dick went numb. After the first few minutes, the penis was numb enough to allow higher and higher voltages to pass through the shaft. To the man, it just felt like a really good fuck, but by the five minute mark the pleasure nerves in his penis were fried. Dirty thoughts and dreams still gave him boners, but he couldn't get himself off. Ironically, while this one robbed a man of ever feeling sexual pleasure again, scientists were able to foil the intent of the device by using anal probes to stimulate the prostate and obtain semen for fathering children.

Eventually, the peaceful war did not succeed. Most of the devices were detectable once they were known about, and easily avoided. At this point, humans began to consider destroying all androids. Plans were on the table for introducing the new generation of modern mechanization that would no longer require even industrial robots. Weapons were in the design phase that would target only androids, such as magnetic pulse canons.

In response, the rogue androids stepped up their sterilization campaign to “non-peaceful” methods.
