This Bubbler Bottle connects to your gas mask hose and can be filled with a liquid of choice, usually water.

 

You can use it to enhance your breath control play. It increases the breath resistance and the bubbling sound is an add-on too. The more liquid you use, the harder you need to work to get your air. Another great option this Bubbler bottle offers is to fill it with another beloved liquid of choice, or to add a couple of drops of poppers to the mix.

 

Breath control play is great fun, especially in combination with bondage. But safety first: solo breath play is a known killer in the kink scene. NEVER play alone. NEVER leave your partner unattended, not even for a minute.
