No solo breathplay. NEVER.] This is a custom video ordered by SW (brplay_rubber). It was quite a challenge for Xiaoyu-senpai and I think it is the best video of Xiaoyu so far. Please understand that the script below includes dramatic effects, and was thoroughly discussed within the team and agreed by Xiaoyu beforehand. There was no real cheating or surprise for her. Xiaoyu was blindfolded by black tape and wearing a black zentai in this video (with the help from Xiaomeng!). She went inside a vacuum bag and I sucked out air from the bag using a small pump. Take it easy, this was just a warming-up. Then came the real games designed by SW. First of all, she had to wear another latex hood with micro holes on top of her zentai hood. Second, we used a big vacuum cleaner to suck the air out. With its strong power and the breathability of the zentai fabric, the air can be drawn out nearly completely. Xiaoyu was asked to hold her breath inside the vacuum bag for a certain duration, and if she exhales too early, I will punish her by sucking out the air she just exhaled and leaving her inside the bag for a prolonged time. There were five rounds of games, and the targets for the breath holding were set to 30, 45, 60, 75 and 90 seconds, respectively. You may think that they are not that long with air in lungs, but when her body was fully compressed with a very strong negative pressure, it was in fact quite difficult for Xiaoyu to achieve the last two or three targets. Anyway, although there occurred an extra round of punishment due to some reason, Xiaoyu succeeded the first four rounds by not exhaling before the alarm clock went off. I decided to cheat her in the last round: I didn’t set up an alarm for 90 seconds (or any duration), which means she will definitely “fail”. The air was sucked out completely and you don’t even see any air pocket around her chin-neck area. Xiaoyu did a very great job. Although she got a lot of diaphragm convulsions, she managed to hold her breath over 96 seconds before she had to exhale. She started to panic immediately because she thought that she failed the challenge. As a response, I switched on the vacuum cleaner again… Her solo was impressive. She had very little stale air left. Even though she needed to rebreathe this little amount of air, she must inhale with great effort to counteract the strong negative pressure, which exhausted her quicker. After a while she twitched and went BO. I opened the bag and exposed her to fresh air, and also removed the hoods on her head in a minute. Her breath came back in a steady rhythm, and her consciousness returned later. Xiaoyu fully recovered after a short time. When she recalled her sensation during the last round, she said that it was extremely painful in such a tight vacuum bag with nearly no air to rebreathe, but upon regaining consciousness, she felt incredibly comfortable. Please note that the last round was shown in multiple camera angles in the video. The single view from the fixed main camera is also attached at the end of the video as a bonus.
