Pandemic

Mousou Jitsugen Media is about to animate a new hentai based on the second chapter of the web manga Pandemic.
It's another story about a world infected with a sexual desire virus. People infected by the virus fall into uncontrollable lust and "attack" members of the opposite sex, and when they finish intercourse, the victim is also infected.
The action of this hentai version begins several years after the incident of the leak of the virus from the pharmaceutical research center where it was developed. Several years have passed since the incident at the pharmaceutical company where the lust virus originated, and the world has forgotten about it. Tahara, a middle-aged gym teacher, receives a blackmail threat from a mysterious man to publicize his voyeuristic prank of which one of his students was a victim, and now he is asked to do something about it.
He requires the three women to be exposed to the virus and sleep with a certain man... Tahara decides to use the virus, he uses it to infect those three women to turn them into slaves.
But Tahara's desires don't end there: he infects the entire school with the virus. Now everyone is infected, and everywhere in the school building, students and teachers are having sexual orgies, while Tahara trains the infected female students with his fat meat rod...

It is not yet known if they are going to adapt more than one OVA.
