Vallery recently heard a myth that you can blow on your thumb like in cartoons and it will cause you to suddenly blow up. She thinks there's no way possible this could be true, so she joking blows on her thumb. But to her surprise, she actually feels her stomach start to feel funny. Oh my god, she's exactly expanding, it worked! But it's working a little too good! Vallery is blowing up at a rapid rate and is afraid she is going to explode! She heard that riding a dick will help you deflate quickly so she begs for you to help her before she explodes! It starts to work and Vallery's size starts to go down as fast as it went. But Vallery starts to get greedy and decides to give herself another blow but this time it's out of control....she gonna BLOW UP!
