You wake up in a hospital bed, there's been an epidemic outbreak. You're infected with a virus and they take you to a hospital where everyone is infected, even the medical staff. You ask the nurse if there's a cure and she says they're working on it but they will a semen sample from you to find out if you have the gene. Don't worry, the nurse will tell you exactly how to stroke and what to do to ejaculate and give her that sample. You could be the one to save the entire human race!
