This T-splitter lets you split one gasmask hose into two outlets. You can use it to enhance your breath control play and it enables you to regulate and reduce the air intake. Use one outlet to allow for fresh air and the other to sniff your fav smell (whether it’s stinky socks of smelly sneakers or aroma… Your fantasy). 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.
