I know it's not going to be messy enough for some people, but for me there was just enough mud for this to get seriously bonerific by the end.
There are a handful of similar catfight vids that get muddy enough to be of interest on this producer's site, foxycombat.com (do a search for mud) .... but don't look at the price tag if you have heart trouble.
And a random, totally unrelated bonus: These jokers promised their Kickstarter backers a mud wrestling video, and then they thumb wrestled while standing in a mud puddle. HYAR! But the blond smears a handful of mud across her face first and it's surprisingly hot, so maybe they outsmarted themselves.
Whoever the Foxy team are, they've targeted their load well - natural setting, no tattoos, wonderful-looking girls, barefoot in the muddy grass, and no holds barred. Lovely. A bit like some dreams I used to have.
