It could be about some other strange creature that licks hands in a scary way. Maybe it's a shape - shifting monster that pretends to be friendly at first and then starts licking hands in a menacing manner. This can be really terrifying as it plays with the victim's sense of safety.
There could be a cursed object that causes anyone who touches it to start licking hands uncontrollably in a scary way. This object might have a dark history, like being used in some evil ritual. And as people start to exhibit this strange behavior, it spreads fear among them.
It could be scary because licking hands is an abnormal and unhygienic behavior. It might be associated with some kind of mental disorder or possession in a horror - themed context, making it seem very strange and terrifying.
In such a story, it could be that the person who licks hands gradually loses their ability to communicate in a normal way. Instead, they start making strange guttural sounds while licking, as if they are being controlled by an unknown force. This force could be an ancient evil that has been awakened and is using the person's body to manifest its presence. As the story progresses, the person's appearance might also change, becoming more and more distorted, with their eyes taking on a glazed and menacing look.
Once upon a time, there was a dark forest. In this forest, there was a strange creature that made a 'lick lick' sound as it moved through the underbrush. A hiker got lost in the forest and as night fell, he heard that 'lick lick' sound getting closer and closer. He hid behind a big tree, his heart pounding. Then, he saw a pair of glowing eyes and a long tongue that seemed to be tasting the air with every 'lick lick'. The hiker was so terrified that he couldn't move, but luckily, the creature moved on after a while.
I'm not sure specifically what this 'humans can lick hands too story' is about without more context. It could potentially be a strange or unique anecdote, perhaps related to some kind of experiment, a cultural behavior, or just a very odd personal experience someone had.
The origin could be from people's fear of the unknown in nature. Maybe they heard strange animal sounds in the wild that they didn't understand, like a lizard's tongue flicking which could be the 'lick lick' sound, and their imagination turned it into a scary story.
A hiker was lost in the woods. He came across a small, seemingly friendly dog. The dog licked his hand. But soon after, the hiker started seeing strange apparitions. Every time he closed his eyes, he could feel the dog's wet lick on his hand and then see a figure of an old woman who seemed to be angry. The hiker later learned that the dog was rumored to be a spirit's companion in those woods and the lick was a mark of being haunted.
No, it's not very appropriate. Feet can carry various bacteria and germs, and allowing a dog to lick them might pose a risk to the girl's health, such as causing infections.
Once upon a time, there was a small village. In this village, there was an old, abandoned house. People said that at night, you could hear strange licking sounds coming from inside. One brave child decided to go and see. As he got closer, the licking sound grew louder. When he peeked through the window, he saw a shadowy figure licking the walls with a long, black tongue. He ran away as fast as he could and never went back there again.
