I've always fantasized about trying this with someone, and since we can't be together... you'll have to follow my instructions. I want to blow you up like a balloon, I want to see your body expand as you pump yourself up, I want to see you inflating your body! I want you blown up like a big, round balloon. Get your pump ready (manual or automatic, whichever you prefer), grab a little bit of lube, and push the nozzle right into your ass hole, and then start to pump. Feel the air entering your body as your body slowly expands. My goal is for you to get so big that you POP like a balloon!
I want to see your body expanding and inflating as you pump your body along with my instructions. I want to see your body becoming more and more round as you push yourself past just bloating. You're my personal balloon, growing bigger and rounder and firmer... until it's time that you burst!
