Your girlfriend is tired of being flat chested. You get her a super hot tight little white dress but her tits are just not big enough to fill it out. She's disappointed, but you brought home something else for her as well. A magic micro bikini that turns tiny titties into giant melons! The next morning she wakes up with huge knockers! She rushes to try on the white dress and it fits perfectly, her new chest filling out and stretching the tight fabric. What you didn't tell her though, is that the bigger her boobs get, the more of a bimbo she turns into! Welcome your new big titty bimbo girlfriend!
