Alien Sex With Secretary
She'd always heard that if you went into the jungle alone and entered the stone temple naked, a sex monster would come to you. She never heard that there might be two!
In a post-apocalyptic world where humans are at war against mutants, some female soldiers pretend to be patrolling when they're really meeting up for wild monster sex.
Ever since the takeover, the monsters go door to door. If you don't have enough security, they break in and take what they want. This is the reality in a post-apocalyptic world.
