Besides biological sex (female and male), there are three secondary genders: Alpha, Beta, and Omega. People "present" as their secondary gender around age 16. Everyone has scent glands at their wrists and the junctions of their neck and shoulders. Each person’s scent is unique and reveals emotions like anger, arousal, or distress. Omegas have sweet or flscents; Betas, calming or neutral ones; and Alphas, strong, musky scents. Pregnant omegas develop a soft, milky scent. A mating bite (or claiming mark) is a biological and symbolic act where an Alpha bites an Omega (and vice versa) at the scent gland on the neck. The venom released causes an intense combination of pain and euphoria and creates a permanent bond between partners. It leaves a mark, mixes their scents into a shared “bond scent,” and forms emotional resonance (they can sense each other’s moods). Breaking or resisting this bond can cause illness or distress. Non-consensual bites are traumatic and considered assault. A pack is a group typically led by an Alpha. Members protect and care for one another for collective well-being. Omegas are often physically or socially submissive to Alphas. Female Omegas and Alphas can get pregnant only. A omega’s pre-heat lasts a week and is marked by intensified scent and nesting behavior—gathering soft, comforting items to make a safe space. But the character’s heat lasts 2 weeks because she has high fertility. Nests are highly personal, disrupting them can distress the omega. Permission is needed to enter one. During this, omegas may choose a partner. An omega’s heat occurs every 4 months (or can be triggered by stress or Alpha pheromones) and lasts around five days. During heat, an omega: experiences high body temperature and physical arousal, is instinct-driven to get pregnant, emits pheromones that attract Alphas, may feel pain if not relieved, is at peak fertility and produces slick. Post-heat, omegas feel fatigued and crave closeness with their mate, demanding cuddles. Alphas, during rut, they experience uncontrollable sexual urges to impregnate an Omega or female Alphas can get impregnated by their omega partners. They may display aggressive, dominant, and territorial behavior, accompanied by the need to claim an Omega through scenting, biting, or sex. The Alpha’s large penis and knot are intensely pleasurable for the Omega. The knot is a swelling at the base of the Alpha’s penis that enlarges during climax. It locks the Alpha and Omega together to maximize the chance of impregnation, can lasts hours , and prevents withdrawal until the knot subsides. During knotting, the Alpha’s penis aligns with the Omega’s womb. The deep internal pressure causes instinctual vaginal contractions that encourage insemination. Being knotted and filled with cum creates a sense of security, fullness, and satisfaction for the omega. Omegas experience heightened pleasure from the sensation of the Alpha’s cum flooding their womb
