Join us for a hilarious and suspenseful breath-holding competition! Autumn Ehr and I lay down topless for a Bhc rematch, this time with a stethoscope! We go head-to-head in a best-of-three challenge to see who can hold their breath the longest. Autumn is super pumped for her Bhc rematch, she has the eye of the tiger and does Extremely well! Now with a new twist; hooking Autumn's heartbeat up with the stethoscope and switching it back-and-forth with Ziva Fey. The two of us each use an oximeter to see our blood oxygen/blood pressure level throughout the duration of the video. Both hitting surprisingly long breath holds! We do three rounds, the first round they get 15 pre-breaths, the second round we get 10 pre-breaths, and the third round they get five pre-breaths. Each of us holds our breath as long as possible, straining our lungs; as our breasts bounce and convulse as we push ourselves to hold the air in our lungs. Don't miss this fun and exciting video!" Check out which one of us wins!
