With out another word Amanda threw herself at Amy, catching her off guard and causing her to fall to the floor. The whole house shook as the two huge women rolled on the floor, their huge muscles flexing with effort. While Amanda was now bigger than Amy, Amy was still no pushover, and she managed to fend off most of Amanda's punches and kicks. Finally Amanda managed to sock Amy right in her perfect six pack abs, knocking the wind out of her. Amy gasp in surprise and went limp for a moment. Amanda laughed and got to her feet, flexing her huge biceps. "Looks like I'm too much of a woman for you to handle "big" sis!" Amanda continued to caress her muscles, marveling at their incredible size and definition. "God I feel so POWERFUL! I must be the most muscular person on earth!". As Amanda continued to admire herself, Amy's eyes drifted to the floor beneath Amanda's bed, where she spied the gun, glistening in the dim light. Shifting her eyes she saw that Amanda was too obsessed with her own body to notice her, and with a quick grab, Amy reached out and snatched up the gun. She suddenly jumped to her feet, and Amanda's eyes widened in surprise and fear. "So you think you're the most powerful person on earth huh? Not anymore!" with that Amy pulled the trigger and moaned in ecstasy as raw power filled her body. She roared in triumph as her muscles bulged beneath her skin, her head neared the 8ft ceiling as she flexed wildly. "YES! YESSSS! THE STRENGTH! THE MUSCLES! THE POOOOWWWEERRR!" she screamed as she orgasmed, her juices flowing down her now gigantic thigh, larger than Amanda's waist. Veins traced their way beneath her taunt, tanned skin, fueling her muscles with more strength. She brought her arms up over her head and flexed in a godly pose that cast Amanda completely in her shadow. Amy's huge tits swelled along with the rest of her, till each was nearly twice as big as a watermelon, perfectly shaped and firm to the touch. Amy cupped one breast with a mighty hand, as the other slid down past her incredible eight pack abs to a throbbing clit. The gun lay directly between her legs, and Amanda was afraid to reach for it, let alone move lest the now god-like Amy crush her without a thought. As her growth subsided, Amy let out a blissful sigh and opened her eyes her traps now nearly enveloping her massive neck. "So this is what it feels like." Amanda didn't know what Amy was talking about. "What...what does what feel like?" she stammered. Amy's huge hand suddenly shot out and grabbed Amanda by the throat, lifting her up with ease. "TO BE A GODDESS YOU INSIGNIFICANT WORM!" with her other arm she flexed the largest bicep on earth, laughing deeply she tossed Amanda to the floor and placed her hands on her hips. "I've become more than human! I've become a fucking GODDESS! I can't even describe how powerful I feel!" Amy couldn't believe how amazing she felt, and she imagined all the possibilities now at her finger tips. Life was going to be very different from now on. What would she do first with her new found power?
