No solo breathplay. NEVER.] This video starts with a sexy dance! Xiaoyu-senpai was wearing her black latex catsuit, a corset and a pair of high heels. She warmed up herself with the hot dance and then put on a breathplay hood. It was a long take without editing. Xiaoyu was under the breathplay hood for more than 10 minutes without a break. She only got very little fresh air with her each breath through a small hole, and meanwhile she was asked to do “anaerobic exercise”: sit-ups and squats. A few times she wanted to remove the hood but was stopped by me. At last, I let her take a sit, but when she thought it was finally finished, I pinched the hood to close the breathing hole… she was completely exhausted after this endurance test. She deserved a good rest after the exercise, but of course still in an anaerobic way. She was again under the breathplay hood, and the breathing hole was closed by a piece of tape. She did this for four times, and between the second and third times the hood was not even taken off, but only the tape was removed for a while. In the last time, her struggle was so powerful that she even freed her left arm from the armbinder and her face became red-grey. Enjoy the video!
