The satyriacs are a speculative post-human species from the book "All Tomorrows" by Nemo Ramjet.

Originally, aliens known as the Qu changed the human genome, body, and mind into that of pets called Hedonists. For them, it was especially difficult to reproduce so that they didn't overpopulate, and so were able to be designed to have copious amounts of sex. From the Hedonists evolved the Satyriacs, a sapient but sex-driven and animalistic species of post-humans living on many different worlds.
