Another long session with different breathplay tools has been summarized into this video.
Xiaomeng was wearing a Japanese one-piece school swimsuit and blindfolded. Her hands were bound behind her back. Her lower face was completely covered by white sticky tape except her nose, so that she can still breathe freely for a while. First, I used a nose clip to pinch her nose a few times. This was very efficient, and her breath was highly restricted. Then I used another piece of tape to seal her nose. Air leakage was reduced further, and you can see the contour of her open mouth under the tape when she was trying to suck in air but got nothing.
After I finished playing her nose, with the tape still on her face, I enclosed her head using a plastic bag. She was breathing her own stale air and kept struggling. The bag was replaced by a swim cap later and this definitely increased the difficulty of the breathplay. Her reaction was strong.
Then it was time for a reward for her hard play. I asked her to lie in a vacuum bag with a vibrator. She started massaging her private area and I started sucking the air out. She can enjoy the stimulation from both the little stale air inside the bag and the vibration. Soon she reached to a very strong orgasm. After a short break, she was vacuumed again for the last time and without the vibrator to distract her from the pain…
