Xiaoyu is a Prototype Tester

Beschreibung: Xiaoyu-senpai took a long break and is finally back. “What are these?” With a first glance Xiaoyu found something new in the corner of our studio. “Oh, those are new prototypes from Qianzhi K, to be tested.” I answered. “I want to test them!” Xiaoyu looked very excited. OK, then she became our prototype tester. She put on her black latex suit, and I restricted her legs and arms with metal beams connected to a metal collar. She can then only sit in a weird M-leg posture. I took out the first item. It is a latex breathplay hood with a tube connector. As no tube was connected so far, it worked in a similar way as a breathing hole. I taped the connector by film dressing, so began her rebreathing of her own air inside the hood. She started gasping quickly and presented me a gray face when I lifted the hood at the end. The other item looks like a transparent oxygen mask, but with a breathing valve attached. Let’s call it valve mask in the future. The valve has four small breathing holes which can be closed by a rotating lid. I put this mask over her nose and mouth, and push her down to the floor. She was slumped against the wall, lying on her side. She looked extremely sexy in that M-shaped leg open position! I closed the holes on the valve one by one, and when they were all closed, Xiaoyu was suffering from a high breathing resistance. To make it even worse, I spanked her bottom continuously, and she can’t dodge or hide because of the metal restriction. That was so much fun! In the next scene, Xiaoyu was sitting on the bondage frame and fixed. She was wearing a latex hood with open holes for eyes, nostrils and mouth, with the valve mask on top of it. Firstly I played by closing the valve plus tickling her, but soon I decided to do it differently. I put a plastic bag over the valve and taped it closed. Her rebreathing began again. The transparent valve mask and the bag turned white gradually, indicating the condensation of water vapor as well as implying the increasing level of CO2 in this closed rebreathing system. In the last part of the test (or game?), I finally found a matching tube for the breathplay hood with a connector, so we switched back to that item again. What can we do to the hood with a connected tube? I suddenly had an idea and stuck the open end of the tube to a pump. Let’s vacuum the hood! As expected, the hood collapsed quickly, Xiaoyu cannot get any air, and she also lost any air she breathed out. No rebreathing. Her respiratory system has been vacuumed without the use of a vacuum bag! We will definitely revisit this play in the future. Special thanks to Qianzhi K (X: @RIGHTSNEED) for their support of items. Xiaoyu, as the tester, must be now writing a report about her feeling and thoughts. What will she say?
