No solo breathplay. NEVER.] Because of holidays and travels we haven’t posted any update for quite some time, but we are finally back to business, and this time it is with Xiaoyu! The content is about a swim cap and latex hoods. Swim caps are good breathplay items, but their sealing is always tricky. One day I was just thinking, what if I seal the swim cap with a tight latex hood? Then came an experiment and Xiaoyu was the volunteer. This combination turns out to be amazing! Let’s see what Xiaoyu said. “It is so tight, tighter than inside a vacuum bag. I can’t talk, but only scream shortly. When I tried to pull off the latex hood with my wrapped hands, I can feel that there was plenty of air still contained inside the air bag of the hood, but useless. The air just never went in under the swim cap. My lungs became empty very fast.” Yes, we can see that a vacuum was formed by looking at those big skin retractions in between her neck and clavicles when she was struggling with inhaling. She collapsed very quickly with empty lungs, and even after I removed the latex hood, she had no power to remove the swim cap with her wrapped hands. I am the only one who can save her. The other day we decided to try the same combination differently: a latex hood inside and a swim cap outside. First, Xiaoyu was wearing a black latex hood with nostril holes. The swim cap was put on top. “It is not as bad as the other way around”, Xiaoyu said, “the sealing of a swim cap on a latex hood is good, much better than on a bare head, but I can still rebreathe a little bit under the swim cap, so my lungs were not empty, although the little air became stale quickly”. I think her description sounds too gentle, but her action was really explosive: she even broke the tape that bound her right arm! At the end we replaced the black latex hood with a classic breathplay hood with no breathing hole. Apparently the pressure of an extra swim cap on top shrank the size of the air bag of the hood, and made her stay much more difficult than usual. “I was dizzy and confused at a moment”, she tried to recall what happened, “I felt that you removed the swim cap. I thought, oh, it was finally over, but then only found that I still can’t breathe fresh air, and I was feeling worse and worse. Why? Oh no, I forgot that there was still a breathplay hood on my head and there’s no hole on that hood”. Her words sound quite exciting, right? I think so, and she likes these experiments too. Can’t wait to see her future adventures.
