Ky jelly deposited on the boob by an erect penis in the process of mounting.
One hot lady discovered boob lube, while mounting a verile young man.

1) drool from a sleeping or catatonic woman's mouth that has trickled down to her breasts, therefore lubing them
Ever slip a chick a tranquilizer? She's so passed out she has boob lube all over her titties in about 2 minutes!

when doing a fat chick dry and you wipe the sweat and oil from under her boobs and use it for lube.
I was doin big Mary and she was dry as cat litter so I got some booblube from under her tits and it worked great. I even found a sandwich to snack on afterwords yum!
