"Fifty Shades of Grey" has already taken the publishing world by storm, but is the world ready for dinosaur erotica?

A Jezebel writer recently uncovered the short works of two authors, Christie Sims and Alara Branwen, who write erotic stories featuring dinosaurs, orcs and even imaginary weretigers, the Daily Mail reports.

These odd books are available for purchase on Amazon and Kindle, the sellers cautioning: "Warning: This is a tale of beast sex. This story was written to unlock your darkest fantasies and innermost desires. It is not for the faint of heart and is not your mother's erotica." The covers feature beautiful women dressed in lingerie while dinosaurs lurk closely behind.

The authors of the bizarre new series imagine a world where humans and dinosaurs co-exist, releasing their novels in the wake of unusual porn genres that are finding success in niche markets online.

In one book, "In The Velociraptor's Nest," the main character is a cavewoman whose tribe "treats her like a piece of meat," and it is not until she brings back baby velociraptors to her cave that things take a very unexpected turn.

"When she goes out in search of fresh meat, she discovers a clutch of baby velociraptors and decides to kill them and triumphantly bring them back to her tribe," reads the synopsis. "That is, until their father shows up and blocks Azog's way out of the cave. Azog must use all of her womanly wiles to get out of the cave, which includes doing things she had never dreamed of."

The book, only 18 pages, contains the following excerpt: "Azog stood, back to the wall, clad only in damp buckskins, waiting for the beast to slash at her torso until she lay helpless and bleeding on the damp cave floor. She wondered if it would kill her first, or if her limbs would be sliced from her body as the beast gorged on her. Instead, it reached out with a clawed hand to snatch at her damp animal hide as it clung to one shoulder. Azog felt the kiss of sharp claws against her skin as the hide slid from her shoulder and exposed on naked, heaving breast."

The book has yet to receive any reviews on Amazon.
