No solo breathplay. NEVER.] Finally, Xiaoyu-senpai wants to try a vacuum bag with empty lungs again. In this video, she has been vacuumed and compressed for eight times. Part 0. Warming up. Xiaoyu was wearing a panty, pasties, and a masquerade mask, and lying inside a vacuum bag. Air was sucked out until no air was left inside the bag, not even in her lungs. She started her struggling early but got into the right mood for vacuum breathplay. She was ready for more. Part 1. No air. She changed her outfit to a blue zentai. The smooth suit made it easier to have any residual air extracted and allowed her to move her arms and hands a bit in the vacuumed bag. She was compressed four times in a row. Each time I prolonged the time of extracting to make sure her lungs were empty. She can hardly make any sound, not more than a very short “Ah”. Of course, with no air in her lungs, she can’t stay long in the vacuum bag, but every time I released her as late as possible. Part 2. Little air. I wanted Xiaoyu to stay longer inside the bag, so I decided to do three rounds of vacuum bag with a little air left. In the first time I asked her to hold some air in her lungs and I extracted all other air out of the bag. It didn’t work very well that she can’t keep all air in her lungs due to the strong negative pressure in the bag. She got nearly empty lungs at the end and started to panic quickly. In the second round I shortened the vacuuming time and she eventually reserved enough air to persist longer. Of course, this only means she suffered longer before she was released. Xiaoyu was exhausted already before the last round, and for the first time she collapsed completely during breathplay and started crying. I just continued as planned. She kept on sobbing quietly inside the vacuum bag and seemed not being affected by the lack of oxygen at all. Her zentai hood was stained by her tears. After a while, she suddenly stopped crying and started breathing heavily and seriously. She commented afterwards that when she was sobbing, she was naturally out of breath and became slow to react to the increasing carbon dioxide level. Only at a certain late moment, she suddenly realized her predicament and had to adjust her breathing rhythm. I felt sorry to the crying Xiaoyu, but she said crying in a vacuum bag was also a unique experience to her. Do you like it?
