This is not a phalanx of phalanges; there are only two people per scene is this emphasis on digital manipulation sans a computer. In a bow to conventionality, every sex scene (with hardcore FOOTage) is virtually identical and true to the foot fetish theme.
Each of the 10 girls has exactly six words of dialogue. She says the name of her male co-performer (2 words) following by "It's time to jam". At this point, after the guy sucks and fondles her feet for a while, she alternates between jacking off his dick with her feet and blowing the dick - which is sufficient cause to add F2M (foot to mouth) to our sex act abbreviations. What we need now is a word, like facials, that fits cum shots on feet.
