No solo breathplay. NEVER.] When arriving home, Xiaomeng thought that I was not at home and decided to play with her own breath and masturbate. When she gagged herself with a white sock and tape, put on a gas mask and got ready for joy, I sneaked up on her and tied her arms behind her back. She can only moan from her gagged mouth, and did not know what to do under the restriction of ropes and the gas mask. I fixed a vibrator to her and covered the breathing hole of the gas mask with a condom. She started struggling soon, and I was enjoying seeing the condom being inflated and deflated. After that I replaced the condom with a rebreather bag, and I can hear clearly that her breathing became rapid. I released the bag only after there was nearly no fresh air inside. Later I also played her with a latex breathplay hood and a swim cap. Xiaomeng fell off the bed and started crying, but I ignored and just continued with the plan. I sealed her nose with tape too. She can’t hold her breath anymore, but the vibrator was still running. At last, I decided to push her to her limit by closing three layers of plastic bags on her head. She recognized her terrible situation and resisted without success when I was putting on the third bag. She was so scared that she leaked quite a lot of urine on the floor!
