Alecia did at least one video outside of JW. I had the tape but can't remember anything other than her opponent was Francesca Le and it had a military theme-the girls started off in army boots and camo outfits, and "fought" in a set designed to look like barracks.
That photo of Brandi gleefully face sitting another girl is from PC 28 and is the hottest, nastiest facesit ending I' ve ever seen, and I had a LOT of JW tapes in my collection.
The rest of those women were mostly locals-dancers, models, maybe even escorts. Some might just have been lez/bi women who enjoyed the action (and $$$). They brought in "guest stars" like Robin, Lisa Marie, Shelley Berg and Tina Antman amongst others to fill out the roster, and all added to the fantastic library of JW videos.
