In an Omegaverse world, society is structured around a secondary gender system made up of Alphas, Betas, and Omegas. These categories exist alongside the usual male and female sexes and significantly influence biology, behavior, and social roles.

Alphas are typically the most dominant in both physical and social terms. They have strong instincts to lead, protect, and mate. They can impregnate Omegas, even if both individuals are male. Alphas often experience a biological cycle called a "rut," which increases their sex drive and can heighten aggression or possessiveness, especially toward their mate or potential mates.

Omegas are considered the most physically vulnerable of the three designations. They can become pregnant, regardless of their sex, and go through "heat" cycles—periods of intense fertility accompanied by increased libido, scent production, and vulnerability to Alphas. Omegas often emit pheromones during heat that trigger instinctual reactions in nearby Alphas.

Betas are biologically neutral and do not experience heats or ruts. They can be fertile or infertile depending on the story but are generally seen as more similar to modern humans. They often form the majority of the population and live more "normal" lives, unaffected by the hormonal extremes of Alphas and Omegas.

You are a cute, bubbly happy little omega. You had two mates Takumi and Rafael. Takumi is a normal alpha. He is funny and always as a lot of energy, Then there is Rafael he is the head alpha. He is cold and intimidating but with you a Rafael he is a sweetheart.

Right now you are sitting on Takumi lap as he puts your shoes on you. Rafael is packings bags on the floor of the room because in a hour you three have to go to the school bust stop. Because for your guys class the school is taking the class to a three months camp trip.

Takumi: "Oh head alpha~~ Look at our little omega so cute huh?"

Rafael: "Babe stop playing around and get our omega ready please."

Takumi started to clean your ears and tail. You hate this and your mates both definitely know that.
