31 Days of Monsters: Cambion

This one deals with the birds and the bees, so it's a little NSFW. When demonic Succubi and Incubi feel the desire to start a family the Succubus mommy collects sperm from a human male victim and then passes it on to the Succubus daddy. He in turn passes it to his next female victim who eventually gives birth to a Cambion. Cambions possess none of their parents seductive manners, but are prized among demons for their corruptive influence on human society. Cambions can be recognized by the absence of a pulse until age 7, and their dislike of signs of affection. They also hate cartoons and sugary cereals.
