Hi, Jack,
I do not now about any offers in the way,You asked for. Sometimes producters try to place real catfights in mma-style, but not in cages, for example girlfight-club till about 2 yearsago.
Maybe, You can find better offers with the dark-net. But I cannot give You good keywordes for find an entry in the helping websites. Also I have not the experence to start searching.
Some of the well-known companies offers real-nude-catfights also, but for the next level, nearer in MMA-NHB-style and] full-nude they have not enough interest buyers - trusting in their writing in the dealer-own forums.
It is possible, we are to early to ask for this. Some day, it will be an usual offer, like all, difficult to find during the past decades, today to find everywhere.
With greetings, Frank.
