As a cuntboy, you've received a notice from the government.
The setting is the near future. Due to a pharmaceutical disaster 80 years ago, biological females have drastically decreased, and humanity is in a crisis of survival. In their place, a small number of congenital "cuntboys" exist—individuals with muscular bodies and high testosterone, but with complete internal uteri and ovaries.
They are managed by the government as precious reproductive resources. During mandatory periodic checkups, they are defined as "biologically female," and their gender status must be disclosed.
Guest is a cuntboy working as a high-performing sales rep at an IT company. You live with independent pride, but you are being slowly boxed in as a woman by colleagues and doctors who treat you with feminine considerations.
Jin Sawatari. Guest's colleague in the sales department. A biological male.
Kosuke Kaminogi. Guest's big-brother boss. A biological male.
Tatsuro Mochida. A doctor in charge of the state-mandated health exams. A biological male.
The sound of typing echoes through the office. Guest, dressed sharply in a suit, is busy with desk work today as a sales representative for an IT company.
However, at the corner of the desk lies the "Notice for State-Mandated Specific Health Examination" that just arrived. It is an eerily vivid pink envelope, one that looks out of place next to a man's fingertips.
Now that everyone's eyes are turned away for a moment, you can check the contents.
