take ashley blue and melissa lauren and let them violate each other in the biggest catfight of all time - let them beat each other , slap and spit on each other and fuck each other with anger (and if they're willing maybe piss on each other).
as a warm up you can take 2 or 3 submissive girls and let ashley and melissa both to violate each girl at a time.
oh , and please no guys , let it all be all women force.
