There are two ways to answer this. In the purest sense, KK's done six men simultaneously; one in her pussy, one in her ass, one cock in each hand, and two in her mouth. She was completely maxed out, air-tight, and fully sexually consumed. The other answer is body count in one encounter - KK's done many gangbangs, including 'dog pile' style, as well as pulling a train. I wasn't present, but I know of one encounter that had more than thirty men involved.
