Experiment Failure!? Friends Conducting Female Body Sound Observation Experiment Who's the JAV actress in this video? Amateur? Name revealed!

A long-awaited experiment conducted by two female friends observing the female body! This time, they use stethoscopes pressed against each other's chests to record the sound of their heartbeats. However, the heartbeat sounds are extremely faint, making recording quite challenging. Nevertheless, this label proudly releases even experimental content as a full-fledged work. On the other hand, the swallowing sounds while drinking water were captured successfully, resulting in surprisingly clear audio quality. This release also includes multiple angles of the same scenes, greatly expanding viewing options. Additionally, the interview segment is shared with other simultaneously filmed works, allowing viewers to enjoy deeper, more comprehensive content.
