I can assist here old friend.
Seeing that it was a 30yr old insincere, uncaring of relationship status HO like Cat, i think it is safe to assume ALL TOES and some foot were in play down there.
Up to the ankle for a non-respecting ho like her.
As for normal people, a rub of the vadge area thru the panties against the ball of the foot is a pleasant entree and litmus test as to what you can get away with in the foot fetish fucking frenzy that is a spa being filmed by 8 + cameras .
Having no negative reaction to this, and even the odd "ooh and ahh", the next logical step is to try remove the panty to the side; getting maximum exposure to her holiest of holies with your (hopefully not too infested) tinea twinkle toes.
Then further rubbing til the wetness is a bit more slippery than carnation milk across a laminex table.,, and even a thermos has no issue being inserted into a Cat like ho at this stage.
Brushing the fake tits gets you points, dreaming of her twin sister in there as well gets you off quicker.
Reading this in Sandra's fifty shades voice will immediately dry any vagina; making a pinky toe near that region feel similar to a fire extinguisher penetrating a virgin ass.
Alas, when cat puts the ho in alcohol, Lawson had no option but to insert whatever wasnt visible
PS
The human mouth has 700-800 more germs than any foot ( other than Sam's, that could pass any industrial strength cleaning test)
Noxious, is it true that in her diary Cat requested she go in spa with Sam from there on in?
With all his spares?
