Ariana (and I can't belive I was the first person to mention her!) She was an exotic, raven-haired, olive-skinned beauty from the '90s, who did a lot of fetish and domination porn, often working with her husband Luc Wylder, or with women. She had pierced nipples, a few tattoos, and a stern look on her face that made her a perfect dominatrix. I'll never forget a scene she did in Every Woman Has a Fantasy 3 where she was working over a masked man (perhaps Tom Byron?) in a dungeon, and ended up fucking him with a strap-on. Damn, that was totally hot.
For similar reasons, I'd love to see Jeanna Fine again. Mature ladies are bigger than ever in porn, and her aggressive, intense sexuality would be perfect these days. I'd love to see her do some fetish work for a website like Meanbitches.com (femdom), Romanvideo.com (facesitting and smothering), or MenInPain.com (femdom).
