38 Weeks Pregnant Belly Expansion, Belly Bursting and Splat Fetish The Story All video my belly getting bigger suddenly and I pretend it gets too tight and cut to black with a scream and a SPLAT sound effect, different outfits, more than 10 scenes. My belly inflation with alien babies that make my belly get too big. I push it out quickly in small increments to act like a growth spurt and really freak out as I'm about to burst! Believable belly bursting.
