This is my first non erotic piece. There is NO sexual activity in this text. It is merely a scene setting for later, more erotic texts to follow.Do not read if you are looking for action! It is fantsay, so it maybe a little far fetched for some!
As ever comment and vote as you see fit. More will follow!

The year 2140 and the world is a very different place.

100 years ago strange craters began appearing in large fields, parkland and deserts. People were baffled by them. Some said it was alien life, but such statements were laughed off to begin with.

After some years of these craters appearing, concerns began to grow. They were causing damage to the farmland across the entire planet and the numbers of these craters were increasing dramatically.

After about a decade odd people began to appear as if from nowhere. They were bigger and taller than human beings, with dull greyish skin, but otherwise much the same, if somewhat more Neanderthal in their features and gait.

It didn’t take long for the human race to connect the enormous craters to these strange appearances.
The Governments of the United Nations went on the offensive against these intruders, attempting to drive them out.

The aliens, as they became know did not speak, but communicated in grunts and odd sounds.

They did not attack humans, despite the animosity that they faced. Instead they largely ignored the human beings that abused and attacked them. But they did not move away from civilisation.
Instead the creatures inhabited abandoned buildings, out houses, factories, warehouses, power stations and even garden sheds. In fact any where that humans built or inhabited, the aliens were not far away.

They didn’t appear to feed, they just thrived on man made spaces in cities, towns and villages.
More and more of these odd alien folk appeared.

The more the armies of the world attacked and persecuted, the more the intruders colonised society.
It soon became apparent that it was very hard to kill the intruders, without the use of explosives, which obviously was highly dangerous and controversial when dealing with civilians in ordinary neighbourhoods.
Knives and guns were rendered useless against the intruders. They did not even break the tough hide like skin!

Within 35 years towns and cities were being evacuated and bombed in some of the larger continents in an attempt to rid the planet of these creatures.
But this caused overcrowding in other cities and settlements that started to develop on the outskirts of urban areas and besides the bombings did little to quell the huge numbers in which the intruders were appearing.
They would follow the humans wherever they went.
Scientists began to put forth theories that these creatures were parasites.

Space parasitism was the term that was coined internationally.

Soon, all across the world society began to collapse. Governments were overthrown, schools, universities and colleges ceased to exist.
