For our 2nd Xtreme Challenge, we bring you none other than the gorgeous Cali Kobra. With years of dancing sculpting her muscle toned legs, we knew it was going to be a very TIGHT one. Even after shooting 3 videos prior to this one, Cali manages to hold Jay in her dangerous reverse for 17 minutes. He tries so hard to pry her legs apart, knowing that he is paying her by the minute, but Cali keeps squeezing harder every time he tries, making him realize that he is in for the long haul. Towards the end, when Cali starts feeling the burn, she uses every last drop of strength to clamp down until her poor victim is knocked out. AMAZING!
