After eating a huge lunch and snacking all day, my jeans are so tight. They're digging into my big fat belly and leaving marks. I had to get some relief, so I snuck into the school bathroom to unbutton my pants and let my fat gut breathe. But while I'm there, I can't resist fucking my bellybutton and playing with my piercing, trying to stifle moans as other students go in and out of the bathroom. I almost get caught slapping my belly so hard it turns red
