Decided to write a story directory to see which ideas I've covered, and have yet to cover! I'll be keeping this list updated, with bonus teaser descriptions of stories I've yet to publish.
Every story I link here has adult action and content with a heavily featured kink. I've tried to keep spoilers to a minimum (and innuendos to a maximum), but you can easily guess what happens to me in each :p

While I was writing this list, I realised that several terms are quite similar. Let me define their differences:

Method/Controller
Latex/Goo: The Other slides over and into the host body to take control. The original host body and mind can still be recovered.
Symbiote: The Other is physically dependent on the host to live. The original host body is forced to fuse with and depend on the symbiote as well.
(There may be overlap, ie Latex Symbiote)

Effect
Possession: The Other takes control of the host body, with the original mind intact in the passenger seat.
Takeover: The Other takes control of the host body and pretends to be the original.
Corruption: The Other twists the host's mind and morals to suit its own will and desires.
Hypnosis: The Other relaxes the host into accepting new ideas and behaviors as if they were their own.
Suggestion: The Other steers the host's thoughts naturally into its desired outcome.
Merging: The Other and host combine into a new mind and body.
Body Swap: The Other and host swap bodies with minds intact.
