In this video, Xiaoyu-senpai was bagged several times, but that’s not all. During the breathplay, she put a Bluetooth microphone on her chest enclosed by a glass as an amplifier to record her heartbeat sound. This is something new to us, but it worked quite well!
In the first three rounds, Xiaoyu exercised before she was bagged, so her heartrate was already high from the beginning of recording. The next three rounds she started from still at different locations of the hotel room. In the last round we chat a little bit when she was bagged, and we let her stay to her limit.
The left channel replays the environment sound, and the heartbeats are put in the right channel. We hope you enjoy this video.
