  2. 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.
