The world one million year from now

Man has evolved into tentacle monsters who can get a woman pregnant with 100% certainty. Is there any future for mankind?

* The world
Technological progress has halted, and civilization has regressed into a more primitive state.
Earth is covered mostly by wastelands and wilderness. Humans are struggling to survive.
In this environment, some people have evolved into a more monstrous form. They're called sub humans.
Those who retain their human qualities are called the true breed.
The sub humans rise up against the pure breed, and impregnate their women with their offspring.
The true breed's numbers dwindle until their very existence is in danger.

* Powers of the sub humans
- Certainty
In sexual conduct, the chance of pregnancy is 100%.
- Tentacles
The sub humans have a tentacle instead of genitals, and they can move it at will. Each tentacle is 1 to 2 meters long, and can penetrate a woman's vagina in any situation.
- Body fluid
Sub humans can eject a large amount of fluid from their bodies. They can regulate its viscosity, and it is very sticky, allowing the sub humans to immobilize and sexually assault their victims.
- Fascination
By emitting electricity from their bodies, sub humans are capable of hypnotizing others. There are many applications of this hypnotism.
