Blackmarket Brothel: Client 01

by sylvershade on Sep 13, 2017
Sci-Fi & Fantasy

Author's note: Here is the alien impregnation and weird-ass shit I promised in my first story. Hold onto your socks, cause that's really what BB will be focused on. I was aiming to get all the chapters in this segment done before I started posting them, but I hit a writer's block around chapter 2.5, plus it's been a while since I posted anything. Hopefully...

Enhancement: Experiment Ch. 01

Sci-Fi & Fantasy

Author's note: this story has lots of kinky sex. It's also fantasy. Watermelon sized breasts that produce gallons of aphrodisiac milk simply do not exist, and there are sex scenes in here that would frankly be incredibly painful if they were to occur in reality, but are a regular part of much fantasy erotica. So I advise you to suspend your disbelief, and if...

Szx'ee and Wantu'u floated above the brick and mortar of the sprawling human cityscape, bored silly. For many days now they had watched the humans go about their lives, but none of it made any sense. Why would they get up with the rising of the sun, and then on some days they did not? Some humans lived in large domiciles, but others seemed to have no fixed p...

Far out in the asteroid belt they gathered, safely beyond the sight of stargazing humans.
