The Cockbound Codex unveils a world where existence itself is forged through carnal acts and the relentless pursuit of power. At its heart are the Futanari, a species defined by four distinct genders, each meticulously engineered for their role in a society where sex, mana, and dominance are inextricably linked.

The Dom: The "muscle mommy," is the apex. With her massive, engorged phallus, she's the ultimate architect of power, refining mana and shaping her pridemates through explicit sexual acts.

The Bitch: The "hot, athletic, sexy type," possesses an internal phallus she can externalize for combat and mana cultivation. Agile and strong, she embodies cultivated prowess and serves as a warrior within the pride.

The Sow: The "curvy bombshell with big boobs," is the nurturing vessel, optimized for mana absorption and incubation. Her ample, mana-filled breasts are reservoirs for the pride's future, and her body is built for nurturing and gestation.

The Slut (Fem): The "femboy cutie," is the receptive courtesan, biologically specialized for mana storage and pleasure. His purpose is derived entirely from his "cockbound" status, serving as a living conduit and storehouse for mana and genetic material, often through anal impregnation.

In this world, every thrust is a ritual, every orgasm a surge of power, and every body a living testament to the carnal engine that drives civilization. Mana is the lifeblood, constantly exchanged and refined through sexual acts, making physical prowess and sexual functions direct measures of status and power. Reproduction is highly controlled, with Doms engineering new pridemates on demand, dictating their genetic destiny through intimate acts. Even death, through the brutal process of "dusting," is a sexualized act of mana and genetic plundering, reinforcing the absolute dominance of the victor.

The Dom, often simply referred to as a "Futa" in common parlance, represents the apex gender of the species. Her physique is meticulously "precision-crafted by evolutionary design to command, bind, and breed." Doms are characterized by their physical unaging, extreme resilience, and remarkable high-speed mana recovery. Their primary organs are central to their dominance. They possess a hyper-endowed, immense phallus that is thick, veined, and radiates mana heat, remaining persistently aroused or semi-erect as both a sexual and magical organ.


 This organ is a marvel of biological engineering, functioning as an "alchemical processor of raw mana," allowing the Futanari to control magic through the manipulation of finer and finer grades of mana and also allowing such refined mana to be used by other members of their pride.


Complementing this, Doms have massive testicles capable of storing high-grade mana, and full breasts that are actively used in ritual mana transfer. The rhythmic motions of jerking and fucking are not merely for pleasure but are essential for the process of mana condensation and pressurization within the phallus.


The ballsack, with its unique magical ridges and flaps, precisely controls temperature and pressure, facilitating the transformation of liquid mana into gaseous mana. 


Furthermore, a Dom's breasts are specialized networks comprising trillions of tiny fat cells, each functioning as a miniature balloon filled with liquid and gaseous mana. Their perpetually perky and firm appearance serves as a visible indicator of their magical reserves, with sagging being a social faux pas signaling low mana. These breasts also possess the ability to discharge plasma, which interfaces with the aetheric field, enabling advanced magic. 


A Dom has internal organs that facilitate the processing of Mana in it's various stages.


In Futanari society, Doms are the undisputed "center of pride society—commanders, magical architects, and breeders. All others are biologically designed to orbit them." Their presence dictates the social order, and their word is considered law.
