I work in an office building. What a boring way to start, right? On the contrary, this is no normal office building. So you won't be surprised to hear that this isn't a normal story. I had been working in the building for two years before I noticed anything was amiss. I had shown up every day in my suit and tie. I walked to my cubicle, which had no pictures...

The Fallen Ch. 01

Sci-Fi & Fantasy

Thank you, dear reader, for giving my story a look. My apologizes if it seems a bit slow at first, but I promise there is a steamy and somewhat lengthy love scene at the end. This is the first of (hopefully) many chapters, so I wished to attempt creating some depth in the main protagonist. The usual disclaimer: This is a work of fiction. All characters inv...

Harriet Kono sat in her lab frantically twisting the ends of her long dark hair. For the second time this year she had lost control of her cerebral enhancer project. She blamed unknown variables in the new software and the unfamiliar and strangely alien hardware that was thrust on her by Imperial Corporation. But mostly she blamed Kent Orlando. "You and yo...

"Um, Mistress? Can I, uh, can I get up now?" She asked, squirming slightly where she sat, partly from the growing discomfort and embarrassment at calling Gwen by such a title. The redhead looked at her, almost seeming not to realise what she was saying, but realised the brunette had been sat there for quite some time.. "Oh, yeah. Sorry, um, you can move ar...

Ailanthia stretched like a cat on the soft black sheets, letting out a deeply contented sigh. She felt the wonderful heavy weight at her waist and one of her light-green hands slid down over her gloriously curved abdomen. She bit her flushed lower lip and let out a low moan, her skin feeling so sensitive where it had stretched taut to accommodate her cum-stu...

Edraele leaned into her lover's warm embrace and let out a contented sigh. "Oh, I really needed this... I felt awful after that meeting with Gaenna." Luna held the Maliri Queen close, making her feel safe and protected. "You're not that person any more, Edraele." "I know... but revisiting those horrible memories is always disturbing. It wasn't me that did...

Author's Notes: I'm happy to hear back from people who enjoyed the first and second chapters of this story. As of when I'm submitting this chapter those are the two already on the site. I hope you'll also forgive the more character focused third chapter which is almost a part 1 to this chapter setting things in motion to occur later on. Chapter 5 is also ha...
