Xiaomeng Feeds Xiaoyu Her Survival Air

The idea of a breath feeding has been around for a long time, but we always lacked the core equipment—standard gas masks typically don’t have interface ports on their exhalation valves. That changed when we received this silicone pup hood from Pupjoi (X: @Pupjoi)! It is equipped with dual RD40 ports and can be configured with diaphragms to act as check valves, making it the perfect gear for the air supply role in a breath feeding.

After a quick game of rock-paper-scissors, the pup hood was assigned to Xiaomeng. One port was set as a single-way intake valve to draw fresh air, and the other served as the exhaust port, connected by tubing to the single-way intake valve on Xiaoyu’s gas mask, who was secured to a chair with tape. The other key element of the setup is the KENZE pressure valve inserted in the middle of the tube. This ensures that Xiaoyu cannot simply inhale to pull air through Xiaomeng’s system. Only when Xiaomeng actively exhales, generating positive pressure across the valve, is the path opened, allowing Xiaoyu to suck in that high-CO2 secondhand air!

Hoods on, tubes connected—the conveyance of secondhand air begins. Naturally, Xiaomeng wasn’t going to miss this chance to be the Top. Xiaoyu’s very breath is at Xiaomeng’s whim—Xiaomeng doesn’t even need to use her hands on Xiaoyu; simply holding her own breath forces Xiaoyu into synchronized breath-holding.

Wait, this setup feels a bit like self-harm for the sake of control? Xiaomeng also gets winded from her own voluntary breath-holding. Nevertheless, Xiaomeng maintains a huge advantage: she inhales fresh air, while Xiaoyu is forced to breathe exhaled exhaust with dropping oxygen and rising CO2 levels. Furthermore, Xiaomeng initiates the hold fully prepared, while Xiaoyu often finds her air source cut off just when she’s exhaled and is desperate for the next breath. There were several moments when we could distinctly hear Xiaoyu desperately squeeze out a faint “I can’t!” with the last remnants of air from her nearly empty lungs; the sheer helplessness was stunning.

This test was a complete success! Xiaomeng was thoroughly satisfied, and Xiaoyu was suitably dizzy. I have already begun silently planning: how to indirectly control one person’s breathing by manipulating another’s next time. See you then!
