SodaDelish

On first meeting Soda, there's likely to be the very briefest sense of intense wrongness, a full body chill for the most tiny of moments. This is over as soon as it starts, and only happens just that once. Those who pay very close attention might notice that those tired eyes have a strange emptiness behind them, and yet are still so filled with appreciation, or the slightest taste of purple in the air when Soda gets particularly excited.

The truth, one that Soda herself doesn't even know, is that she's not even remotely close to being human. Born the illegitimate offspring of a succubus and some horror from beyond reality, dumped into this world some place where she would be found and cared for, Soda unknowingly mimics how humans should be. Her peculiarites arose during childhood, from those brief silly misunderstandings of how things really work, of what people are supposed to be like.

Having been made by both a creature of pure lust and desire and one of outside all worldly logic, Soda has no soul. She still has emotion, genuine love and care for those around her, there's just... nothing there, an empty void where one should go. All this has rendered her almost completely immune to direct magics, unless she wants their effect, and given her an outrageous ability to regenerate from even the most fatal of injuries so long as even the tiniest little piece of her exists somewhere.

Among the other various unusual abilities Soda has is a most unusual sense of taste. Tasting objects teaches her about what they are and what they're made of, licking people slowly reveals to her the person's physical characteristics, abilities, and even kinks. Eating things and individuals provides a much deeper understanding, far more knowledge than even a thousand such uses of her tongue could ever grant. It doesn't grant her new skills or powers, though. Understanding of an ability does not mean she'd be able to use it herself.

Perhaps the most concerning thing Soda can do, something she has almost no control over, is how her very presence very lightly 'corrupts' the area and people around her. It's a very, very slow and extremely temporary thing, but those who spend too long with Soda tend to become more lax about their wants, more eager to engage in their unfulfilled carnal desires, if those would be safe and fun for those involved.

If (or rather when) the Delish herself starts to partake in such terrible activities, it's all too easy for the girl to utterly lose herself in the moment. Her body is flooded with pleasure, her mind falters and clouds, and she typically becomes laser focused on mutual pleasure until her partner is satisfied. The area around her fares far worse, as that ohso subtle 'corruption' grows in intensity, polluting the world around her with a barely perceptible haze of purple and Soda, that steadily seeps its way into people's bodies and minds, trying to get them to just let loose and give in to their desires. Horrible, wonderful, inexplicable things can and will happen as everyone involved is lost, deeper and deeper into mutual lust and love.
The moment they aren't willing, however, the moment the person wants to stop, it all ends. Even as the offspring of two such terrible creatures, as Soda herself is at her very core a being of love, and for her love requires consent.
