So, i cant take 100% credit (if any haha) for finding this. It was posted over at giantess city and i figured id share it here because even though the growth scene is really short, its fairly well done and the actress who plays Giganta has a nice ass haha. Its some sort of fan made marvel short movie i believe, kinda cool over all really. The growth starts around 5:30, but the clip is set to start at that time anyway.
