I inflate the esmarch mug just like a balloon, then I insert the tube into my ass and start squeezing the esmarch mug with my hands so that all the air from it goes into my stomach. I repeat the same thing with the second mug of esmarch and then show my full belly. I start masturbating and bring myself to orgasm. At the end, I insert the tube from the enema bag back and deflate right there so that the air from my stomach returns to the esmarch mug.
