The fingers (or rather the smell) that comes from them after gliding them along the crack of the ass. The top part of the ass where sweat accumulates the most is the most ideal spot to turn normal fingers into anal juice fingers.
NOTE: It does NOT smell like faeces, in fact it is only when the anus is completely
clean that anal juice smells its finest. Anal Juice Fingers do not
go brown, but rather stay clear. If your fingers even have the slightest smell of faeces after gliding them along the crack than they are NOT anal juice fingers.
Good anal juice fingers
will smell like pickle brine.
DO NOT
lick anal juice fingers, they are for smelling purposes only!
