Sonja is at the Doctors office for a treadmill stress test. She lets her ample assets hang out as she goes topless and steps onto the treadmill.

Sonja is at the Doctors office for a treadmill stress test. She lets her ample assets hang out as she goes topless and steps onto the treadmill. First she tries walking on it without any leads as a warmup. Soon Dr.Betsy places the many EKG lead electrodes onto her chest, fixes the cables and starts the machine. The speed is slow to start but soon the speed increases. Sonja’s big natural breasts jiggles with each labored step. You can see this from all camera angles including a worm's eye view from the bottom up! When Sonja starts tiring, Dr.Betsy checks her BP and her heart sounds with a steth while she is walking. Soon the test is over, and Dr.Betsy lets her sit down to rest while she checks her vitals again (with BP and stething) and takes the leads and electrodes off so she can dress. A must see for big natural breasts and treadmill stress test fans!
