  1. Genesalt by Undead3

    4 months ago

    A Parasite prototype meant to infiltrate and then slowly and covertly convert planetary populations into stock to be incorporated into an alien stellar Empire is accidentally released on a unsuspecting planet without any of the safety or control measures its designers intended in place. Will the unknowing victims of this new lifeform on their world suffer catastrophe, losing themselves to mind broken slavery, enter into a orgy of confusion and , or become uplifted in the most unconventional of means?

  2. F.D.F. -- Federal Department of Fucking by yournewbestfriend

    5 months ago

    First, a disclosure and tip of the hat to Reddit user Elderhentaigod, who's post inspired the premise for this story -- https://www.reddit.com/r/dirtypenpals/comments/wlj1fu/f4futam_the_first_and_only_pornstar_president_of/ In this story, you play as a member of recently established federal agency established to create "sexual chaos"... which basically fucking horny people so everyone feels sexually satisfied. Without giving too much away, there will (hopefully) be a version with a sci-fi futa twist and a version without. (No guarantees, though). This world is what I like to call "semi-freeuse," so consent is important and necessary, but also almost always given. Obviously, this is a radical warping of reality, which is part of the fun.

  7. Laboratory Fun by Hypnoticus

    8 months ago

    The reader gets to enjoy intricate sexy experiments. What new boundaries will be pushed at the laboratory? Is there something else going on? What's really happening at the lodge? I put a heavy emphasis on a hypnotic style of writing. Often-times the reader will be entranced to imagine, feel, and endure all the many pleasures and pains associated with every intimate encounter. Please feel free to leave comments, like the chapters you enjoy, message me any constructive criticism or to let me know if you'd like to see a particular scenario written up and I'll see what I can do.
