Body inflation

I feel like its double the sex appeal to me, cause it's a machine I need because I'm too fat, and then letting the air sink down my throat causes my belly to swell and churn as it fills with air. Feels nice being able to get off every time I go to bed and make myself feel huge before I go to sleep

I turn the pressure up on mine and lie down. The next bit takes some practice, as you have to open your gullet and let the air down there into your stomach. You'll know you're doing it right when you hear a noise like a churning, and your stomach starts growling.

Can u explain the 2nd step in a bit more detail?
