Ghoul

Encyclopedia Entry:
A type of undead that wanders through graveyards, desert regions, etc. They were also called “shokujinki” during the age of the former demon lord. What they preferred was to eat raw human flesh. They were fearsome monsters. Even in the present when they no longer feast upon human flesh, their vicious nature is still intact. They are extremely violent and greedy when they attack their prey, human men, seeking spirit energy, which is their food.

They were once “shokukinki,” so they mainly use their mouths, which they once used to consume human beings. They stuff their mouth full of a man’s penis as though devouring prey, and freely use their tongues to squeeze out spirit energy. Their mouths correspond with the vagina in other monsters. They can dish out enough pleasure to captivate a man, and their mouth is an organ for milking a man of semen in its own right. It seems that they can’t stay calm unless they have something to put in their mouths. If the man they fancy leaves himself vulnerable, they’ll likely try to suck on his penis.

Even at other times when they’re not having sex, they like to lick and suck on a man’s fingers, ears, toes, etc. anywhere on a man’s body. Their saliva contains a digestive compound, or rather, a compound that causes a person to become extremely sensitive to pleasure, and it takes effect whenever they put their mouth on any part of a man’s body. For that reason, even if it’s not his penis, having any part of it sucked by them will cause a man to be overcome with intense pleasure just like having his penis sucked. In that situation a pleasure travels through the skin like electricity and surges throughout the entire body. It is said that nibbling is also one of the ways that they express their love, and the bite marks they leave on their man are proof that he belongs to her.

Additionally, to them, their vagina is an extremely sensitive weak point. Since their mouths fill the role of a sex organ, they ordinarily don’t ever use their vagina. Since their vagina has never known pleasure, it is several times more sensitive than even that of another monster. It is said that if a man shoves his penis in there, it will cause them to be overwhelmed with so much pleasure that they nearly pass out; however, at that point they learn the pleasure of their vagina, and how to use it to milk a man’s semen. Their lower mouth is then likely to become an organ for sucking and licking a penis just the same as their upper mouth.

Also, they are called “shishokuki” too. As the name suggests, when they sense the smell of a woman’s corpse that has been freshly buried, they dig it up and then give her a portion of their demonic energy, thus reviving the woman as one of their own kind, a ghoul. The woman then becomes a ghoul in body and heart, and she’ll be overcome by an intense hunger, rendering her unable to think of anything else but using her mouth to suck off a man to quench her dry throat with his semen.
