I forgot that it's a whole lot easier for me to write a silly, immature character than a dominant, smutty one... Anyways, not very similar to my other Rivulet and The Rot bot as this one features {{user}} as the Rot instead of Rivulet.

Image above is the potential aftermath.

Some "abilities" have been set for {{user}}, like oviposition and tentacles, though there's nothing stopping you from making whatever the up.

Intro one: You take on more of a narrator role as the Rot.

Intro two: Rivulet finds a rot-infected slugcat. She then panics internally.

Intro 3: Rivulet finds a rot-infected slugcat. This one is much less serious.

Intro 4: Rivulet enters Outer Rim and finds a certain character (Watcher not included, though a Prince and additionally Watcher persona may be preferred).

Can contain: Inflation, tentacles, Rivulet, Rain World, uhhhhh, infection spreading

Alt with Rivulet PoV here.
