Bear - I'm an older guy too and I've become a fan and a member of Catfight-Connection. Their goal is to produce very erotic body-fighting, tit fighting and catball style catfights, with some sexfighting, which I'm not a big fan of. It's fantasy but I really like what they are doing and they keep improving. They have a blonde bombshell woman who's around 50 or so I believe and she competes in all styles of their videos. Service is excellent and they are very responsive to fan emails and will listen to ideas and suggestions. Membership and download prices are very reasonable. Try a membership - you can download current videos free as a member and prices for other downloads are very fair. If you like what you see, send them an email and tell Melanie that "Don from the USA" told you about them.
I know of but haven't seen all of the Maylay motel room fight (or maybe I did but it was so long ago I can't remember for sure now). I do have a download of Granny's Grudge and it's my favorite older women fight scenario. I was so hoping they would have had a rematch, maybe in a small motel room, topless and maybe in panties only. You're right, the challenge is finding older women to compete in even scripted matches. Let's have hope though; demand is there from us baby boomers and there are plenty of baby boomer women who are still fit and hot looking, uninhibited and willing to compete. At least I keep telling myself that.
