Sexy petite blonde Emerald sits in her sexy lacy black lingerie with her Littman stethoscope over her heart. She is having a good lung day so she blows multiple colorful balloons and ties them up while giggling and smiling, as her heart rate increases with every balloon she blows. Ziva sits behind her in her strappy black lingerie and listens to Emeralds heartbeat monitoring the changes as she blows balloons. Enjoy Emerald's strong rhythmic heart pumping as her chest expands and contracts with every balloon she blows.
