One sided please! None of this back and forth forever. A little back and forth in the begining ok, but when one girl gets an advantage she should proceed to beat the other up. None of these spectular recoveries that belong on WWA.
Contrasts, yes, tall, slender, small brested vs shorter, heaver, larger brested. Winner either, I dont care but the winner should punish the other's brest.
Light skinned vs darker. Love to see the looser crying and begging the other to stop.
And different advantages, ie: faster with longer reach vs stronger. boxer vs wrestler, Dirty fighter vs clean. street brawler vs marshal arts.
We need some well written stories.
