**** Planet Xe'Far - 20 years ago - Earth time ****
Planet Xe'Far was under great turmoil as the war raged between the ruling management and opposition parties. Lives were being lost at an alarming rate to the point where the species were almost extinct.
The inhabitants of the planet identical to a virus on earth. The only difference is that the species can survive without a host just not reproduce. Multiple viruses can share one body, combine and mutate to show different symptoms. They can also change shape, size, or look at will. The planet did not house any other animals or any other species. The Xe'Fari they called themselves were alone on the planet.
Xe'Far was the 3rd planet in the Andromeda Galaxy with its sun. The conditions were very close to the earth. The only difference was that the size of the planet was double of earth.
Being a technologically advanced race, they did not need sex to reproduce. They used their DNA to produce more of their kind. They could produce millions of their kind in a year, however, being in a state of war had destroyed the majority of the machinery.
Being parasitic in nature guns and tanks were ineffective against the species. The war was mostly biological. Mas amount of biological gases were released in their air and food systems.
They communicated using signals emitted from their bodies similar to radio waves.
War proved to be futile, what is the point of gaining power when the entire planet had just a hand full of survivors. Food was scarcely available. They had about a month's supply left at least and that was not enough time to repair damages. The remaining would just starve to death.
The Xe'Fari needed a host to feed on and reproduce. Luckily their search database was still intact, similar to google, however, its database spanned several galaxies. This could understand the dialect of various planets including those of animals.
The earth seemed to be the closest planet with species compatible with the Xe'Fari DNA. It was still a year's travel before they could get to earth in their spaceship and with just a month's supply, they might not make it, however, it seemed to be the only hope.
***Earth - The year 2020***
It was a stormy day in Manaus, Brazil. Thick Dark clouds all over, thunderstorm, and weather warning issued throughout the city. Citizens were warned to work from home if possible and avoid the roads. Parts of the city were already flooded. Their spaceship avoided attention due to the weather. They crashed landed near what looked like farmlands.
All Xe'Fari survivors combined bodies to form a single entity having the size of a single atom. This had to be done to need the least amount of food to survive. However, now one they can no longer separate as the mind is one.
Crypto, the Xe'Fari leader, and the mind in control of the entity. He saw a house nearby and a possible host. Being almost starved, he was not sure if he could bind with the host.

Lucas was having his evening tea and snacks. The day had been a total waste, it had been raining all day and he had to salvage what was left of the crops. He was married to a beautiful girl Lana and had no children yet. They were a young couple wed only 2 years ago.
Crypto made is way to Lucas and entered his body through a wound Lucas got while on the field. Crypto quickly made is way through the blood veins and found a spot in his brain. He attempted to take control of his brain cells, but he was too weak. He was able to gather some strength with the help of undigested nutrients flowing in his blood.
During dinner that night Lucas seemed to have an appetite of an entire village. No matter how much he ate, his stomach kept rumbling for more. Crypto seemed to have moved from the brain temporarily and gown down to the vein entry to the stomach and was absorbing all the undigested food. Despite being such a small creature, he did demand lots of food.
Once Satisfied, Crypto returned to the brain and started taking over brain cells slowly. He started learning how the human mind works, likes, and dislikes of a human. He also learned that Lucas has not been active sexually due to the stress he lives with. That was something that needed to change if the Xe'Fari species were to grow again. He was able to take control of some of his brain cells to control his excitement.
Luna was not satisfied with her relationship with Lucas in bed, however, she didn't want to give up on him yet. It was not that he did not take care of her, he just did not give attention to her looks.
Lucas saw her in the shower dressed in bikini bottoms and couldn't help it but follow her. She spread her arms inviting him into the shower. He grabbed her hand and walked closer to her. He then suddenly pulled her into her arms. She could feel him growing big and hard as she stood so close to him in his arms. Luna slipped her hand into his boxers and started to give his dick a stroke. His erection seemed to get harder and larger as she stroked it. He turned his head towards her and started to kiss her warm lips.
She pulled her panty down and unhooked her bra and wrapped one of her legs around him giving access to her vagina and guided it in. She moaned as his hard dick made its way deep into her. He started to slow and then pushed harder and faster with each pump until he was all the way into the hilt.
Luna was shivering in excitement as she came repeatedly. Lucas sucked her tits as he fucked her hard. She moaned each time he thrust his dick into her. After an hour of sex under the shower, they both came one last time.
