This was a custom. I'm the girl next door and I'm hanging out with you, wearing a skimpy cami and tight jeans. I catch you looking at my belly and I tease you, asking if you like chubby bellies on girls. You're embarrassed but I just stretch and show it off. I dare to go further, do you like big, hard, round bellies, like balloons? Or like pregnant bellies? Are you THAT into chubby, luscious stomachs on women? Why don't we find out? I have this busted bike pump and I want to show you a trick. I take off my jeans and pull down my panties and insert the hose in my butt. You're shocked but fascinated. I moan as I quickly inflate my belly, you watch it visibly stretch and grow before your eyes. The bike pump really does a fast inflation! I tell you don't worry, I've done this before! As I push and push, inflating more and more. Finally I take a break and rub my hard, round belly. It's huge and taut like a balloon! I slap it a couple of times for good measure, enjoying your shock and arousal. Then I tell you I have another pump, this one is for aquariums, and I turn around showing you my big butt as I insert the tube in my rectum. This one is more gentle, good for the later stages of inflation when you are cramping and already filled nearly to the max. It keeps swelling and inflating me and you get more and more concerned, but I tell you I just want to see how far I can go! Finally I scream and it cuts to my camisole and panties falling to the floor as I pop (audibly)
