When Tonics first hit the market people sceptical, rewriting your DNA sounded pretty scary and painful, but people came to find it wasn't either of those things especially with the promise of total reversibility to them. Soon they were everywhere every corner shop had a selection of the most popular Tonics, there wasn't really anything they couldn't do; make you stronger, thinner, taller, fatter, bigger boobs and whole lot more, if you couldn't find it in a Tonic bar then some places could brew you a custom one no questions asked. There were even a few traded on the black market, things like making you stupider or even changing your mind to that of a slave were possible. People went crazy for them, it wasn't uncommon to see a group of women playing chicken in the office seeing who would dare make their ass the biggest and guys doing the same with their muscles or dicks.

But then reports started trickling in people who had OD'd on Tonics or had a bad batch etc, news articles such as "Woman drinks boob-Tonics until she can't walk" or "Woman orders custom multi-Tonic and becomes sex crazed slime." They were usually written off as people being irresponsible with them, that's the price of total genetic freedom people said.

Soon though it became clear repeated Tonic use was not only addictive but unstable, it could happen to anyone and the manufacturer stated that these haywire cases were untreatable, permanent changes to the victims. Some constantly mutated others the effects blew way out of proportion. One man was seen with cock the size of his leg constantly oozing cum uncontrollably. Another woman reportedly afraid her partner would leave her ended up enlarging her nipples beyond control becoming so big she had to wear and extra G cup bra for them alone. If you looked there were endless cases like this and many of the worst ended up in so called Tonic ghettos, bad neighbourhoods where society sent it's degenerate sex freaks to live with others like them.

That brings you into the story who are you and what's your interest in the power of Tonics? Maybe you're a first timer looking to explore them. Or maybe a habitual user use to changing their appearance day to day. Are you one of those unlucky enough to feel the side effects? Or maybe you already have and are just trying to get by with their new body. Gigantic breasts or a cum only diet, endless milk supply or constantly gaining weight. Maybe though it's not for you, maybe I'm your crush that needs a little encouragement to make the first move or maybe I'm your boyfriend a great guy but not quite perfect you slip a Tonic in my drink while we're out and prepare for your dream come true.

The sky's the limit and we can talk about including whatever fetish you like. I'm open to almost anything some of my limits are gore, snuff, bathroom stuff. Anything else is probably fine ask if you are unsure.

This could even go down as a GM prompt if that's you're thing I don't mind writing multiple characters or just the world around you.

If this has given you the perfect idea you are more than welcome to jump straight into it with your opening message.
