Nothing makes Sai feel like more of a giant human balloon than filling herself with air, and playing with her huge belly and bellybutton! Sai dresses down to nothing but a bra and small shorts, and pumps her belly full of air while telling you how amazing it feels and how much she wants you there to inflate her yourself, with lots of bellybutton play. The inflation feels so good that she just doesn't want to stop! But she isn't careful enough, and she inflates herself until she pops!
