Impressed by Akira's strength from their 1st busting, Kim is curious to see just how much her IRON cunt can really handle! Mentioning how she has done plenty of ballbusting, she says Akira's crotch is MUCH stronger than a guys! Kicking HARDER and FASTER with her shoes on, looking hard to see for any flinches or signs of pain on her face- unlike a wimpy man would!
