just thinking about how hot it would be to have belly that's super round and stuffed under a really loose shirt but when the air catches it or when the stuffed person moves, the shirt brushes against the round belly and everyone can see how full it is. you dont notice because you're so stuffed full and trying not to start rubbing it in public. everyone keeps glancing at your belly because they can't believe how big and full it must be in order for it to be sticking out like that
and even hotter if it's a hoodie! the fabric is so thick but the belly is so huge that when you move a certain way it pulls across the crest of it slightly and gives everyone a glimpse of how much you've packed into yourself. you might slip your hands into the pocket to try and give it a secretive rub through the fabric but everyone's gonna know. and then they'll know that youre not just a bit chubby under there, but that you've made your belly this huge and swollen on purpose from stuffing yourself so much.
you really need to rub your belly or shift your position somehow, but they're definitely gonna know if you try and change position - if you try to stand up you're going to struggle. if you try to sit down you're going to be groaning at the pressure on your already tight belly. but you have no idea how obvious you are because you're so stuffed you can't think about anything else other than how huge you feel - and what you're going to eat next. everyone's eyes are gonna be glued to your belly waiting for the next glimpse of how massive it is.
