  3. The Ultimate Transplant by fantaghiro

    2 weeks ago

    PLEASE ADD CHAPTERS! A close friend or family member is horribly injured in an accident. As they lay dying in the emergency room, another patient dies of a brain aneurysm. Both of them are organ donors, so a surgeon decides it's the perfect opportunity for him to try an experimental surgery. He transplants the victim's higher brain (the cerebellum) to the donor's body in an attempt to 'save' a life. Amazingly it works. But the surgery was not approved so the hospital convinces the families to keep quiet, arguing that revealing this operation to the public would bring never-ending media attention to all involved. That means that the patient will have to publicly assume the identity of the donor. What will this mean to your friends and family? Who else will you tell? Although you will spend a lot of time and effort giving support, how will all this alter your relationship to the patient? And how will he or she adapt to a complete change of body and identity? Many transformation stories focus on the change or victim, so I thought it would be interesting to instead have the POV be someone who sees the change from the outside. Writers feel free to explore a change in age, gender, class or ethnicity - and the repercussions that change would have on the main character (and others).

  4. The Dream Slut Chronicles by Robopoop

    3 months ago

    One night, as you dream lucidly, you begin to have the wettest dreams possible. Throughout your usual 8 hour sleep cycle, you begin dreaming about anything you want. You can become a princess captured by horny orcs. A leather clad dominatrix with a varied collection of slaves. A space pirate with a 12 inch cock. Anything your subconscious mind can think up, it can become reality in your dream. Whether it be mundane or bizarre, controllable or uncontrollable, is entirely up to you.

  7. Improved Carbon by Incognito42

    2 years ago

    Welcome to the world of Improved Carbon. It's not a carbon copy of Altered Carbon, but it might be more than a little bit inspired by it. A world where mind and body are no longer interlinked, where bodies are simply "sleeves" to wear. At least if you're rich. If you're not, you might still get a new body once in a while, to replace an old and broken one, but you might not get to choose exactly what you get
