Just a regular day, out running errands, when I got a massive gas attack. I couldn't wait to get home so I stopped at the nearest gas station to let it fly. I'm wearing a black tank top and jean shorts, and I pull them down to sit on the toilet. My tummy hurts and I'm straining to push that stinky air out of my asshole… but some of it comes up the other direction! Buuuurp. All that pushing makes me p-e-e too.
