Cool! Thanks for the post, ITGuy1138! Every contribution helps.
One thing, however: Jessie Jazz's "Jazz Dance" card has a lot of delightful nudity and she does indeed go barefoot a great deal, but she wears high-heeled sandals in eleven scenes. So her card is not really even close to what one would call "barefoot the entire show".
If, like me, you do or would enjoy an entirely barefoot card, I can happily refer you to Jewel's "Forbidden Jungle", Ella Mai's "Sexy Swimsuit", Axelle Parker's "Bath Time", and Bettina Di Capri's "Fitness Fun". There may be others I'm forgetting at this moment. These are cards in which the entirety of every scene is with the woman going barefoot. A shoe never appears. Gracy-***** has a card, "Nightie Night", in which she is barefoot throughout almost every scene. Ironically, she wears a pair of high-heeled pumps for the entirety of two taskbar scenes. My copy of this card has two unplayable defective scenes, so I can't answer for whether they have shoes or not.
I hope you get to enjoy these cards :-)!
