Oops! O balão explodiu no fundo da minha bunda

I thought this would be a nice and chill session of balloon stuffing. Wellll I was wrong. While I was pushing the 60 cm long balloon deeper and deeper into my intestines, I could feel it moving up my belly. The pressure inside the balloon was high but it held up well. But just when it was at the very end and it was completely inside, it exploded! All the air rushed into my belly and out of my ass. My hole was left widely gaping open. It looked so beautiful I just had to fist it on the spot!
