38 Beautiful Girl Body Observation Research Experiment: Heartbeat, Stomach Sounds, Body Temperature and More Who's the JAV actress in this video? Amateur? Name revealed!

She has an ultra-slender 38kg frame and takes part in a unique experiment to record sounds such as her heartbeat and the sound of her drinking water. Various recordings are captured under different conditions, including after physical exercise to raise her heart rate. During an experiment measuring friction heat from her breasts, the staff joked that her A-cup size made it impossible to properly hold a thermometer, which visibly annoyed her. This release includes multiple angles of the same scenes, offering new discoveries with each viewing. The interview footage is shared with other concurrently filmed works, providing deeper insight into her charm.
