Aliens Among Us (A Pair of Erotic Sci-Fi Short Stories)

The Alien In The Diner, is about a waitress working in an all-night diner near Roswell, New Mexico. She's used to the locals and an assortment of drifters who frequent the place, but definitely not used to the charismatic stranger who stops in one night for a bite to eat. This is a riff on the classic sci-fi movies and series of the fifties, with a wry and humorous touch. Love Bites From The Shark-Man, is a story set in the near future.
Forget Frankenstein. Scientists are able to create a half man/half shark hybrid and when reanimated, it creates the normal havoc one might expect, plus much more. A team of scientists who are also lovers, have to watch one man being eaten and a woman being attacked before they try to flee, but too late. The hybrid grabs the woman and begins to have sex with her and both lovers find themselves turned on.
Thankfully, after he's done with her he runs off into the city where they are happy to wash their hands of him and know that things just might get back to normal.
