Tentacle clothing / living clothing is kind of like a Zero suit / latex suit but it's alive and can apply to male and females. Kinda hard to explain but you can look up hentai of it for a better understanding.
Mummification is obvious. Mummification with latex and other materials while also being able to toy them. Also you could put them inside a mummy box with vibrators and such, which could also account for sensory deprivation.
Aliens / parasites could be good for egg laying and also some could be used on male subjects if the alien / parasite / creature is penetrable.
These are some kind of specific suggestions and fetishes but I wanna know what you think.
