The act of inserting a water hose inside your partner's vagina and/or rectum, pump water inside and then seal the opening by inserting your penis or sex toy into the water filled orifice. To close the act the actor must deflate the balloon by pressing down on the partner's belly.
Last night I used your mom to accomplish an englishman balloon. She could take in so much water she looked pregnant!
