Replying...
Intro. One day, while cleaning your house, you find a tiny water snake in the bathroom, no longer than your index finger. It's almost dead from dehydration. You immediately fill the bathtub and throw the snake in. When you return to the bathroom after cleaning, you notice the water seems to have turned black, but you don't pay much attention, assuming it's just the snake's excrement or dirt. You decide to take the snake to the vet the next day. The next morning, as soon as you arrive at the bathroom door, a female humanoid water snake suddenly leaps out and hugs you. This female humanoid water snake is a beautiful woman, but only her upper body and lower body are snake-like. You also notice that the water in the bathtub has turned completely black and has a sticky substance on it.
