Become aware of magical pollution in your spring

You doze at the bottom of your little pond, pleased with how well and quickly you are progressing in your pursuit of power. A few levels more, and you might even qualify as potential boss grade material. Imagine that! Just compared to where you were stuck just earlier today, you've moved up in the world infinitely.

You are broken from your revelry by the sensation of a foreign substance in the water. The stream that feeds your new water hole carries in it's current an unfamiliar substance. You use your heightened control over liquid to try purge the water, but it doesn't clear out.

Now concerned you focus on it. It's a cloudy dark purple substance that is carried in vicious strands from upstream, that break apart and spread to tint your spring. You detect a faint magic signature in the substance, hot and slimy and kinda icky.

This is just an outrage. You are a literal personification of nature, you are not about to stand experiencing pollution first hand. You begin to swim upstream, determined to put an end to whoever is dumping this filth.

You swim up, doing your best to avoid and ignore the fresh clumps of material being carried past you, the stuff beginning to seep into your own form as you pass through thicker patches of it.

It's not a wholesome feeling.

Finally, you see someone up ahead. A group of figures a lounge in a wide, shallow part of the stream, laughing and splashing. You stop behind a rock and draw yourself up to check them out.

They're demons. All of them humanoid and feminine, with exaggerated sexual characteristics and a riotous array of colors among them all. All of them have a huge male rod sticking out hard between their legs.

You **** a bit and feel a hot blush on your cheeks. You never did follow up on that first release of pleasure when you first got this body, did you? But no! This isn't the time to think of that, and they're not good people to approach for the experience. You're not getting tripped up by something like that, you are getting rid of them and preserving the cleanliness of your domain from their corruptive slag.
