The licker felt his groins stirring again. It was that time of the year again. For the Licker, mating was a simple mating ritual like the humans were used too. In fact, the Licker alien simply does not mate. You could say that the Licker is like a bee, extracting pollen from flowers and then inseminating it onto other flowers, the only difference was that the Licker takes both sperm and eggs from both victims (as well as some other bodily fluids) and incubates it in its back which is then implanted with the Licker's DNA.
It's been a while since arriving on the back water planet known as planet earth. Not exactly the perfect place to procreate with the poor genetic qualities of the human race but the Licker had no other options. Having already taken an egg earlier (through an unwilling human female, violently to add), the Licker now needed some viable 'donors' on inseminate it. The Licker smelt the scent of human males in the air,... lucky. Its groin stirs again and it starts to laugh perversely, "Hehehehehehehe..." It then follows the scent of the human males south toward the small building.
The Licker moves down south into the building
Computer says no... *COUGH*
