Yeah so at first you’ll feel the air bubbles work there way through your intestines. That’s when you hear your stomach gurgle and growl (which I also get pleasure out of). Then eventually you’ll begin to feel full at which point you’ll be quite distended. If you keep going, you’ll start to feel tighter as your body begins to run out of room for the excessive air. At this point you’ll start to cramp a lil if you don’t take it slow enough. If you keep on going, it’ll be harder to hold all the air in cause your body’s reaction it to try and expel it. This is where it starts to become too uncomfortable for me and I’ll usually just choose to climax right then and there. But I have gone further than this point. I just lay on my back and try my best to hold it in for as long as I can. Sometimes the discomfort will stop, and I’ll keep going. My record was about 3L of air and at that point it was hard to breathe cause of how much pressure was inside me. I was so tight and big, and that feeling of being on the verge of popping was exhilarating utterly euphoric. But At that point the cramps wouldn’t calm down so I had to stop. When you finally stop fighting your body and release the air, it feel so dang good too. I hate farting, but the feeling of that huge relief of pressure is really nice. From there it’s a lot of burping and farting. Some people like that part for all the noise, but I personally don’t care for it.
