No solo breathplay. NEVER.] Xiaomeng has received a new costume, a latex nun suit. She is fully covered by latex from head to toe. Her facial features are hidden underneath the micro-perforated hood, and her black-and-white uniform are shining in the dark room. The sister puts on a gas mask connected with a 2L rebreather bag over her latex head. A valve is connected to the rebreather bag for controlling her breath. Even when the valve is fully open, the air flow is still narrowed. Xiaomeng feels so hot and starts to massage herself using a magic wand. Later, her arms are bound behind her back by an armbinder, and her hood is changed to a condom hood with only two small nostril holes. The magic wand is still doing its job while her breath is blocked frequently by a piece of tape. Now she takes off the tight condom hood and wears a blindfold and a transparent latex hood. The hood has a small air pocket but has no holes. She is sitting on the magic wand and enjoying both the vibration and the feeling from rebreathing stale air. How many strong orgasms has Xiaomeng reached in total?
