Monster Kien

Orcs

Green or brown skinned, shorter but more muscular than humans, with tusks, they have a high libido and are very potent. Females are rare and males usually kidnap women from other races. Mother-son **** is very common in their society, as males have high sexual needs and homosexuality is frowned in their culture, until they get their own mate it's not uncommon for all sons to fuck their mother. Their semen has addictive properties that help them keep their victims, but it's more effective on smaller races, requiring repeated consumption over a longer time to affect races like humans or elves.

They can be as smart as a human when they are a member of a more civilized village or are assimilated into bigger kingdoms, but the tribes are very primitive and superstitious.

Goblin

As small as a hobbit, but not as liked. Associated with orcs because of their commonly green skin, though brown is not uncommon and there are some rare grey ones. They keep their head shaved because of culture, to show their small single horn. They breed very fast, males have thin and long dicks, that cum a lot, and females have always at least twins, having at least two ovum available at all time. When a male drinks from a nursing goblin’s teat they will start producing a lot of precum, getting milked to feed the female if needed. The effect is very strong in other kien, making men shoot precum with every pump.

Goblins are raised by females acting as caretakers along with other children from the same generation in a brood, this is a necessity when the children are born from slaves, they can be related by blood but with their mating habits I’s impossible to know exactly who is whose sibling or parent. It’s frowned upon to mate with one's brood relatives but no such taboo exists for real blood relatives, as long as it isn’t a goblin who raised you or one of the kids you grew up with it’s seen as ok. This practice allows a goblin to breed with slaves without remorse even if they’re their parents. Some goblin parents intentionally don’t raise their children themselves to leave them available as mates, it’s seen as pathetic and weak but not bad.
