An ABO fan

You stare at the rulebook, but not for long. You already know what rules you're going to write in the rulebook - just something small for yourself, an ABO world. You will erase it eventually, but that doesn't mean you can't play a little.

You start writing:

• Old Rule: There are three sub-genders - Alpha, Beta, and Omega.
• Old Rule: Alphas, Betas and Omegas can be male or female.
• Old Rule: Betas are normal people.
• Old Rule: Alphas are known as the dominant sub-gender.
• Old Rule: Alphas tend to be more aggressive than betas and omegas.
• Old Rule: Omegas are the submissive sub-gender.
• Old Rule: When fucked, all omegas can get pregnant.
• Old Rule: Omegas gets monthly heats, in which, they will crave an alpha's dick. During those times, the omega will release a pheromone that can attract alphas, and only getting fucked can ease the burning heat.
• Old Rule: The probability of pregnancy of an omega increases while they're in heat.
• Old Rule: An Omega's main job is to take care of the children, and get fucked by their mate.
• Old Rule: Omegas are naturally slower (dumber) than both Alphas and Betas.
• Old Rule: Omegas don't need to attend school.
• Old Rule: Omegas can't get a job without their alpha's permission.
• Old Rule: Omegas are precious and should be protected.
• Old Rule: Omegas find their Alpha's scent very calming.
• New Rule: With their parents' agreement, an Omega can attend a special school that teaches them everything they need to know to survive in this world.
• New Rule: I can change my sub-gender at will.
• New Rule: I can cause an omega to go into heat.
• New Rule: I can change other people's sub-gender at will.
• New Rule: If a beta gets fucked by an Alpha there's a chance that they'll change into an omega.
