A World Where Every Woman Became a Hardcore Pervert Begging to Be Fucked

Story

One man's semen saves humanity from the crisis of extinction!? An array of ultra-perverted plays, made into a motion anime, in a world where a mysterious disease that only afflicts women spreads and accelerates the falling birthrate. Synopsis: A mysterious disease, "Onaho Syndrome," that infects only women, spread. Infected women single-mindedly crave semen and become bodies that cannot live without ingesting it. Furthermore, once infected even once, they become unable to conceive at all. Because of this, a terrifying situation arises in which the birthrate declines drastically. As the number of infected exploded and demand for semen soared, a profession was born—the "Onanist," who provides semen to women with Onaho Syndrome. Seiji Taburi (the protagonist), a national Onanist, is assigned to Holy Cross Girls' Academy, renowned as one of the nation's foremost elite girls' schools. At this academy, a certain top-secret project was underway, and they had succeeded in developing a drug that makes even infected women able to conceive. If you ingest that drug and have intercourse with an Onanist, you can conceive instantly. What's more, the time required from fertilization to birth is a mere 10 minutes—astonishing. In other words, it's a fuck-fest harem of sex, with creampies OK and impregnation OK, with bitchy uniformed girls whose bodies are perfectly suited for mating and who are constantly in heat. The overflowing-with-libido, plump, sensual girls, with their estrus pussies craving your semen, wriggle and squirm slick and slippery in the motion anime version too!
