Amanda brushed aside her worries. She was the most powerful thing on earth! To hide her body would be a crime. She flexed her right arm and laughed at the sight of the muscles growing bigger. She realised she needed a place so she could grow without being interupted. "Of course! The old Dunrel place! No one has lived there in years!" She ran completely naked with the gun in hand. She took the back roads where no one could see her. She ran for ten miles but didn't feel tired at all. The new growth must have made her more durable. She kept running until she made it to an old mansion that had long been abandoned. "Perfect..." Amanda opened the gate and stepped inside the grounds. The mansion was falling apart and the wood was rotting. She got to the front door and kicked it open. The muscular beauty stepped in and sat on an old couch. "I have all the time in the world now." She turned the height dial up to 100% and did the same with the muscle dial. She stood back up in excitement. "Goodbye, Amanda! Hello, Super girl!" She pulled the trigger and the beam hit her with so much force that she fell down. She kept her grip steady and allowed the gun to work its magic. She could hear the muscles in her body grow. Her legs grew longer as well. She moaned in pleasure as she grew bigger and taller. "Oh yes!" With every breath she took, her body expanded dramatically. "I'm more powerful than He-Man!" She didn't dare let go of the trigger. The gun buzzed loudly as she absorbed its energy. Her head hit the ceiling and she sat on the floor. Her muscles were immense! Each arm was wider than a person! Her head hit the ceiling again and she got on her back. She shoved the gun into her hungry clit and orgasmed from the energy it gave her. It seems she no longer needed to hold the trigger, because after she had stuffed it into her pusy and let go, it still gave her power. She didn't know how big she would get, but she wanted to be bigger. She crashed through the first floor and was qouickly outgrowing the second. "Make me bigger!" Five minutes passed and the five story mansion collapsed. Amanda was buried under the rubble but still grew. She finally stopped growing and was panting heavily after having orgasmed countless times. She brushed the ruble off herself and stood up. Amanda had become a behemoth. She stood twice as tall as the mansion with unbelievable muscles. She was as wide as she was tall, each leg was twice as thick as a redwood tree. Amanda's vagina was constantly wet, a literal waterfall of cum came down her legs. Each ab on her twelve pack was the size of an SUV. Her monstrous ass looked like two hot air baloons. Each of her perfect tits were the size of a house. Her powerful arms were each as large as small buildings. Her muscular neck could barely be seen by her enormous pecs and traps. Amanda looked around and avery where she looked she saw muscle. "Too bad... I'll never see my toes again," she joked.
