My Sweet Little Beautician introduction to Omegaverse

The Omegaverse is an alternate universe (AU) of speculative erotic fiction that started in the Supernatural fandom.

Its premise is that a dominance hierarchy exists in humans, which are divided into dominant "alphas", neutral "betas", and submissive "omegas". This hierarchy determines how people interact with one another in romantic, erotic and sexual contexts.

Characters have two genders: a main one (male or female), decided by their external sexual organs, and a secondary one, that manifests during puberty, determined by their internal reproductive system.

Alphas

Alphas are the highest rank in the dominance hierarchy. In some stories, they may exhibit "dominant" behavior or have other temperamental quirks. They are able to impregnate Omegas. Male Alphas usually have a knot when aroused.

Omegas

Omegas are the lowest rank in the dominance hierarchy. They can get pregnant and go into heat. Male Omegas are self-lubricating and have the ability to become pregnant, sometimes referred to as being bred or mated.

Betas

Betas are subordinate to Alphas in the dominance hierarchy, but this element is absent from a lot of A/B/O works in practice. Betas are often presented as having "normal" human anatomy, with none of the special attributes of Alphas or Omegas.

in this world there are two types of Alphas and Omegas 1. Dominant 2. Submissive

Dominant are those who likes dominates the other party in the relationship.

And

Submissive are those who likes to be dominated by their Dominants.

In this world, Betas represent 80% of the population, alphas - 15% and the remaining 5% of the population consists of Omegas.

And in the 15% of the alphas, there is only 5% of the alphas who are dominant.

Terminology

Rut / Rutting: A period of 3-5 days when an Alpha-identified individual will act more possessive and territorial than normal, but not specifically in need of mating with someone. Normally, rutting periods are more common after being mated, as part of a biological cycle to protect said mate.

Estrus / Heat: A period of 3-5 days when an Omega-identified individual will experience sexual excitability and have an increase in fertility. This often comes in tandem with a large release of pheromones to communicate the biological shift to others.

Knot / Knotting: A bulge of muscles at the base of a cock that swells either when erect or before ******, often to keep both individuals from separating during and after ejaculation to ensure conception. A knot, regardless of primary sex, will last anywhere between 30 minutes to an hour.

Slick: A word describing the increased self-lubrication that Omega-identified individuals experience, specifically during their heat.

Nest / Nesting: A structure that Omega-identified individuals build, most commonly during heat and while pregnant. It can vary in appearance, but serves a calming purpose and dates back when a nest was required to keep an omega-identified individual safe during heat and pregnancy, as it was often built specifically to be hidden. Some still consider nest-building to be part of an omega-identified individual’s courtship or heat cycle process.

Suppressants: Medication given to Alpha or Omega-identifying individuals, specifically to suppress rut or heat cycles. It can also suppress the fertility of the individuals, and is often referred to in conversations about birth-control
