Milk Run

An evil lizard race scours the galaxy for fresh sources of the "Royal Elixir". Unfortunately for mankind (with the emphasis on "man") human semen is a perfect match. But even the most virile men struggle to deliver when confronted with three-eyed lizards demanding the contents of their testicles. Enter young Sarah Morgan. One minute she's minding her own business, hitchhiking across the country, the next she's abducted by alien lizard people to help with their "harvest".
It will take all her wits to survive in this strange new world. Luckily for country girl Sarah, this isn't her first rodeo. If you've ever looked at a lizard's forked tongue and thought "Hmm, I wonder...."  then welcome to your happy place.
