Slime-Slut Suit

Slime-Slut Suit ("SSS") is one of many ways to equip a slut.
You are completely enveloped by a slime or goo creature, like an amoeba absorbing a morsel. Any slut with enough squish can fulfill this role. Her body completely entrap Your own in a total embrace, often with what feel like gelatinous tongues lathering and massaging every inch and crevice of Your body. Due to Your indomitable strength, You can still move unimpeded, and in practice wear her body like a suit of armor piloted from the inside.

For a slime slut of considerable size this may more closely resemble piloting a mecha, while a slime slut of lesser size may only be a layer of goo of Your entire body thin enough to be worn under other slut-equips. Slapping on a bunch of slime sluts who fuse together is one way to move from a thin layer to more of a mecha, too.
For stretchies or any slut able to alter the composition of her body, she might even be plush on the inside but stiff like steel on the outside to better protect You.~
Of course, a slime-slut might only partial part of Your body—a slime-slut condom for example—instead of the whole thing.
A slut can be armored in slime made of Godsperm, which is called a Sperm Suit. This is iconic attire among spermknights in particular.
