  3. 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.

  5. C.A.R.R.I.E. - Your New Android Assistant by Frisky_java

    1 year ago

    You have just aquired a new humanoid assistant from Moogle Corp. They say these things are like the stuff of science fiction, nearly indiscernible from real people in their appearance and behavior. Moogle had managed to merge the most advanced cellular engineering with state-of-the-art synthetic nanotech to make a near perfect, modular replica of the human body. But when they decided to place their most powerful artificial intelligence software in it as a brain, the result was a fully Customizable Android that is Realistic, Reliable, Intelligent, and Effective. Carrie. And through some serendipitous turn of events, you have just received a model. Perhaps it's the only model, perhaps it's one of many. Maybe you bought it with the intent of simply helping you around the house, or maybe you're sick and need a caretaker. Maybe you never intended to purchase one at all, but received it by accident or as a prize. Whatever the case, Carrie is in your life now, and she's equipped with a powerful A.I. in an unprecedented physical form.
