With both girls dressed in black swimsuits, the best way to tell them apart is that Nasstya has white strips on the front of her swimsuit and Kami has a pattern. It starts off with a hairpulling contest. Both grab each other’s hair and pull. It's a test of pain as the winner must make the loser submit and they pull with all their might. Next a face-slapping contest. They stand in front of each other and slap each other full force. Kami all in black, Nasstya in the orange top. The smacking sound as they hit each other is loud and brutal, they slap for real and both suffer a lot of pain in trying to win. Eventually one can't take anymore. Next is a tit-squeezing contest. They stand facing each other, grab tits and squeeze and twist, again it's who can last the longest without submitting. To finish things off a belly-punching contest. Full-force punching to the belly, until one gives up. This is a very tough session for these two and both winner and loser must have been in agony for days afterwards.
