When she has been struggling for a while, take off the bag and put a swim cap on her face, until she reaches her limit. 2. Cover her face with the swim cap. When she has been struggling for a while, take off the swim cap, let her count from 1 to 30, and put on the swim cap again. After she has been struggling for a while, take off the swim cap, let her count from 1 to 60, and put on the swim cap one more time, until she reaches her limit. 3. Let her exhale all air in her lungs and then cover her face with the swim cap for 30 seconds. After a break, let her exhale all air again and cover her face with the swim cap for 60 seconds. 4. Compress her in a vacuum bag with some residual air. 5. Compress her in a vacuum bag with some residual air. After she starts struggling, pump some air out. When she has been struggling for a longer time, pump air out further, and keep her in the bag until she reaches her limit. 6. Compress her in a vacuum bag when she is wearing a ball gag. Pump residual air out one or two more times, and keep her in the bag until she reaches her limit. Xiaoyu actually BO briefly right before the exact moment when I opened the vacuum bag in the last round. The ball gag in her mouth impeded her reflexive breathing and recovering, but after I removed the ball gag she recovered quickly. It is an unexpected but great ending!
