No solo breathplay. NEVER.] Xiaomeng hasn’t shown up for quite some time. After watching Xiaoyu-senpai undergoing challenges, games and punishment, Xiaomeng just can’t wait for her turn of breathplay. Wearing a shining orange AMORESY catsuit, using special straps to hold a vibrator against her private parts, and getting her hands handcuffed, Xiaomeng was ready to accept an orgasm training under breathplay hoods! Let’s start with something easy, a breathplay hood having a breathing hole. With both the stimulation from the vibrator and from the low oxygen and high carbon dioxide levels, Xiaomeng was quickly into the role and started moaning. Of course I wouldn’t make the training so easy. From time to time I sealed the breathing hole of the hood to expose her to an even higher carbon dioxide level, and when the hole was reopened again, the sudden increase of oxygen undoubtedly brought her pleasure to a next level… Xiaomeng was not yet satisfied after the first round of training. In the second round, she asked me for stricter restraint and stronger stimulation, so I used an armbinder and a breathplay hood with no breathing hole on her. This hood was obviously more powerful. With the stimulation from the vibrator (now in a stronger level) and from the even lower oxygen level, Xiaomeng reached an extremely strong orgasm and can’t stand steadily anymore. I think if I hadn’t removed her hood in time, she would definitely have gone blackout again. Afterwards, Xiaomeng said that she liked this feeling very much, so let’s look forward to a sequel together!
