[Fb/Futa4Futa] A new evolution in scientific discovery, the ability to change one's sex and appearance practically at will
(Transformation, species transformation, impregnation, hyper sizes)
It should be noted, all characters involved, as well as those engaging in the ERP, are 18+!

The last 50 years of scientific discoveries were filled with landmark after landmark of societal-changing discoveries. It all began with artificial chemicals tested on lab animals, proving a success as they were able to induce what some have coined a "temporary evolution". Some compared it to the ability to see into the future, of what could become. Some saw it as a vile way to play God. Either way, science progressed.
In the coming years, this technology was understood further. It wasn't a perfect view into the future of that species that was reflected in its transformation, but rather unlocking the specimen's own DNA. In most mammals that were tested, when they were exposed to treatment, they became physically bigger. They lacked any visible muscle, much more fat being seen on their bodies, but their strength seemed better than ever. They had increased vitality and fertility, turning them almost into sex fiends if exposed to enough of the treatment. Bizarrely, when male subjects were transformed and inseminated, they were discovered to have become pregnant in the process.
Fast forward to today, while it's not too commonplace, the technology has become commercialized. It seems to be much more popular with biological men, as the effects don't seem as impactful in women. Over the counter tablets can be purchased that can allow a temporary "futanarization", mainly being seen as a gender affirming or sex-related medication. It is understood though, that while it is temporary, becoming pregnant while transformed will cause you to never fully go back to normal. Another impact that was discovered, was when having regularly taken the medication, ones own body begins to produce the chemicals, allowing them to change at a whim. Not just that, but if enough dosage is taken after a long period of time, they "unlock" a third form, a form that can only be described as "inhuman" in it's proportions.
I'd like to play as a young man in his early adulthood, stumbling his way into a community of these medically induced futa. Either I'd like him to have a partner, or go between multiple partners. I have all sorts of refs for all forms that I'd love to use.
I'd love to expand on more details in chat, expanding the setting.
Some ideas of people he could engage with: friends, brothers, father, professors, strangers, hookup dates, all sorts of ideas.
I'd prefer to play futa without pussies, but if you can convince me otherwise I might be able to play as a full-packaged futa. I'm also welcome to the idea of playing a scenario where I develop one over time, eventually fully committing to it and becoming full-packaged
Kinks: anal, mpreg, incest, impregnation, transformation, breast growth, cock growth, ball growth, excessive cum, docking, soft vore (cock, anal), rebirth, monster girls, futa, femboys, fu x fu, fb x fu, fb x fb, and many many others~
Please send me a chat request. Tell me your favorite piece of media, as well a kind of character you'd like to play alongside mine. Looking for around a paragraph per reply, and someone who loves to world build. I do not RP on this site, rather on Discord, though I'm all fine with setting up RPs in chats.
Additional note, I have been on a sort of hiatus and began a fresh start with a newer account that I RP with on that site. If we had something going before, please feel welcome to reach out again so we can continue whatever we had going on or start something new!
