Voodoo Balloon Backfires

I just caught my boyfriend cheating on you with my friend and I've figured out why - my friend has gotten several plastic surgeries and now competes for the largest breasts in the world and my boyfriend has a breast inflation fetish. She has breasts the size of beach balls now and my boyfriend cannot help but cheat on me because of it. To stop this once and for all, I have just bought a "voodoo balloon" that is capable of inflating anyone you choose just by thinking about that person and blowing the balloon up. I am going to blow that whore friend of mine boobs up, since she always wanted to be the biggest, until she explodes so my boyfriend can't cheat on you anymore. With that, I slowly blow the balloon up and taunt my boyfriend at each size of the balloon, describing how big your friend is getting. Her over-sized tits blowing up like hot air balloons, her slender body puffing up, she's turning into a blimp as the balloon gets bigger and bigger. I mean, she always wanted to be the biggest and now I'm helping her! I keep blowing the balloon up in my boyfriends face and taunting him that she's running out of room...As the balloon gets as big as it can, I know my friend must be so big and tight that she's about to burst...and that's when I tell my boyfriend that when I pop the voodoo balloon, the other person fills up to the brink and then bursts too! Then, I overfill the balloon and pop! I laugh and gloat at your boyfriend that his blowup doll has just gotten too big and exploded....and then I feel a sudden tightness in my breasts along with a hissing noise. I are blowing up like a balloon but how is that possible?
