I've kind of stopped thinking when reading this. I'm just enjoying the images... Well, except for the censorship.
Also cocoons? So the zombies are gasp mating with the girls to give birth to new life? Who could have seen this coming.
And I know, technically it's probably more of a mutation of existing life, but hey technically it's creating a new species so I think it still counts as giving birth in a way. Lemme have this joke.
