Administer the enema very slowly and gently. an inflatable cath is absolutely necessary with this mixture. Pressure will build up immediately, followed by heat from the cinnamon oil.

My sub has not been able to retain this mixture more than 5 minutes without screaming, so be aware of that. Expulsion will be violent, with a residual burning that will last for an hour.
The club soda and cinnamon oil mix causes EXTREME cramping.
