With a mouse (to your mouth)

This is the story of X. X is a little germ entering someone's mouth. X's vision is somewhat blurred. Its vision is in 'distorted 3D'.

The mouth is the ultimate frontier between the inside of a creature and the rest of the universe. It is the border control. There is a long process before reaching the heart of the body. X aims to re-produce itself into the heart of the body just like a little mouse. When inside the body, X the germ can see, feel and breathe exactly what the creature's body sees, feels and breathes. It's often thrown out randomly. To be a germ is the ultimate fulfillment like a multiple orgasms. A germ can dictate and control a whole body and there is very little anyone can do.
