Xiaoyu-senpai planned to further improve her breathholding ability, so I designed a 15-minute breathholding training session for her. She was very interested in it and immediately requested to do two rounds, even changing into two different beautiful outfits for the occasion.

The training was straightforward: her hands and feet were tied in a spread-eagle position on the bed, her mouth was sealed with film dressing, and I pinched her nose to make her hold her breath. Over the 15-minute session, the first and last breathholds were as long as possible, while the ones in between varied in duration. Between each breathhold, she was only allowed a short period to catch her breath, and sometimes, I would pinch her nose right after she exhaled.

To better capture Xiaoyu’s reactions during the breathholding training, we used three camera angles. Please enjoy!
