ぜったい遵守☆子作り許可証ぱらだいす!!～嗚呼、素晴らしき孕ま世界～

The year is 21XX, and humanity is still on the verge of destruction. The birth rate of the human race has decreased, especially the rate of male births. The current sex ratio of the human race is now 1:107210 male:female, further exacerbating the already overwhelming female majority. World leaders felt the pressure of this birthrate crisis. In an attempt to stop this crisis of annihilation, they established the "SEX New Law" and issued each man a "free sexual permit". Originally disallowing anything but internal ejaculation meant to impregnate, it was eventually decided that men "should not be obligated to insert". Thus, an "oral permit" and so-called "waste fire permit" (for external ejaculation) were established to help with male stress relief.
