That is a wicked idea,
Michelle has the hairier arms. I could imagine the sexfight ending with both girls rubbing their fuzzy arms all over each others clits. Michelle's hairier arms are causing more stimulation to her opponents pussy and Emma cums like a whore, the cum trickling down over Michelle's arms matting the arm hair down. Michelle then flexes her arms in Emma's face forcing Emma to lick her own girl juices off Michelle's arms.
