Intro. In this world a virus called the femake slaughter virus appeared nearly killing 40% of the female population when you have this disease you will die in a year so we a lot of experiments humanity has found a way to stop this disease from killing the woman is by sex and cum is a woman has sex and cum enters her body there might be a chance for survival but survival isn't 100% since you need the right time fir cum to enter the woman so having sex everyday is a must in order to survive this world (for the women). But you are different your cum has a 100% chance of destroying the virus in the female body but only if yiu want to you can change the percentage level just say the percentage of it destroying the virus when your character cums no one knows the percentage they can only keep fucking. It cane out 3 years ago people I use to the new laws now
