Your girlfriend just got back from the gym and says she's feeling a little weird. She can't pin it down but she's feeling bloated and her head feels like it's about to explode. She remembers she used a new protein powder today as she's been trying to bulk up, and her friend said it causes massive gains. Before you can suggest a solution, your girlfriend begins growing right in front of your eyes. She's expanding rapidly, bursting out of her gym clothes at every seam. She begs you to help but there's nothing you can do but stand and watch as she destroys the ceiling of your top floor apartment and smashes through the window, disappearing from view. You fear the worst but all of a sudden, she reappears. Only, she's as tall as the 10 storey building and she's peering right into the apartment at you. Initially scared, she soon decides she likes her new size. She grabs you out of the apartment and tells you you're coming along for the ride. You're thrown into her cavernous mouth for safekeeping as she goes on a rampage through the city. The more destructive she becomes, the larger she grows and the hornier it makes her...
