Biohazardous Affections

A virus is accidentally unleashed upon the world, which turns people into cannibals. These infected can eat normal food and even reason with people until they are compromised. Another quirk to this virus is that it gets virgins, who are attracted to each other, to have children, who can perfectly infiltrate into human society. This story follows two people that must stay pure until help arrives to cure them. Can they control their desires until then?
