Old Man’s Human Breeding Plan (kurai屋)

    Home › R18 Games › Old Man’s Human Breeding Plan (kurai屋)

    Synopsis

    ■Humanity on the Brink of Extinction

    All men of humanity suddenly become infected with a newly emerged virus. Most infected males perish, leaving humanity nearly decimated and facing extinction.

    Among the chaos, some older men survive.

    These men acquire antibodies to the virus, gaining numerous enhanced abilities, inexhaustible stamina, and most importantly—semen capable of impregnating any human woman in a single act.

    The government seizes this opportunity and enacts an ordinance:

    “Under no circumstances may women refuse sexual acts from men.”

    With this law in place, humanity’s repopulation begins.

    ■Impregnate Without Restraint

    Simple rules and controls—just click your preferred woman and breed. Steadily increase the population.

    (Successive assaults trigger different reactions…)

    ■Take Your Favorites Home

    Use right-click to bring women back. Each time they give birth, you can continue expanding the population indefinitely.

    Complete the collection of all women.

    ■Orgy Parties with Other Old Men

    As you grow the population, other men occasionally appear. They act independently and mercilessly assault any women they find.

    Utilize them strategically for efficient population growth.

    ■Customize Your Room

    Earn contribution points as the population grows, which you can spend on furniture. With some creative flexibility, design your ideal scenario.

    Editorial Review

    ★3.2 / 5 — henhenta editorial rating (our own assessment, not the DLsite official user score)

    Old Man’s Human Breeding Plan situates itself firmly in the male-oriented breeding simulation subgenre, a niche category that has grown more mechanically ambitious in recent years. This work leans into unapologetic power fantasy territory—specifically the survival-scenario variant that uses existential stakes to justify coercive sexual dynamics.

    What distinguishes this title is its straightforward mechanical loop: the gameplay strips away narrative pretense and commits entirely to simulation structure. Rather than disguising compulsion within character relationship mechanics, the design foregrounds the breeding cycle itself. You select women, trigger escalating encounter states through repeated interactions, and collect completed subjects back to your base for indefinite reproduction cycles. The “successive assaults trigger different reactions” mechanic suggests some rudimentary variation in encounter outcomes, though specifics are unclear from the synopsis. The right-click mechanics for capture and housing introduce a collection element that’s more explicit about possession than many competing titles. The promised “Orgy Parties with Others” (synopsis cuts off mid-sentence) indicates multiplayer breeding scenarios, suggesting social competition elements alongside solo conquest.

    The comedy tag here likely refers to the absurdist framing—the elderly male survivor protagonist in a repopulation authority scenario carries inherent incongruity that previous works in this space have mined for tonal contrast.

    This work appeals specifically to players seeking unfiltered power fantasy with minimal narrative friction, who prioritize mechanical depth in the breeding simulation framework over character development or romantic pretense. The collection mechanics and expandable-population structure suggest longevity-focused design.

    A mechanical accomplishment in its narrow subgenre for those already committed to breeding simulation gameplay, though entirely contingent on your tolerance for the underlying premise.
