Thank you for reading and responding. I don’t know about "next part." But then I didn't know about this part when I wrote the first part. I suppose I could turn the whole world into a gigantic zombie fuck fest, but these two stories are not about that. They are supposed to convey a sense of existential dread at the realization that the world is unthinkably large and strange and doesn't give a shit, or if it did, we'd be more than fucked.
They are actually inspired by "In the Dust of This Planet" by Eugene Thacker which I found out about on an episode of Radiolab (link below) and subsequently read.
I suppose I could continue it in the fuck fest vein on the satirical basis of the notion that preparations such as Viagra and Cialis strip sex of emotional content by removing the risk of not getting a boner, after defining that as failure. Thus, we become sex zombies not so unlike the people taken over by my body snatchers.
