Amanda's head was splitting with pain and she couldn't focus her thoughts. Her mind swam in a state somewhere barely above unconsciousness. Small sparks of outside stimuli stabbed through the haze, leaving scattered impressions behind. *Her nose itching from plaster dust.* *She felt turned on, very turned on but she wasn't sure why.* *She could hear her mother screaming.* *Her whole body was sore but especially her face.* *She could taste blood.*

"R-robert? What is going on here?" Stacy backed away from her son as his head turned to face her and she could see the crazed smirk on his face. Stacy turned back to look across the room at her daughters slumped body, barely visible behind the couch. "You've killed your sister!" Stacy's voice rose to a painfully loud screech.

"No," Bob said, his first words since he had watched his son grow before his eyes. "She's still breathing, you can see her chest moving."

*Chest moving, she could feel her chest moving...*

Stacy looked closer and could see the hunch of her daughters shoulders and back moving, rising and falling in a rapid fire rhythym. "We've got to get her to a hospital," Stacy took a step forward but was stopped by the rough hand of Robert on her chest.

"The fuck we will, I don't care if that bitch dies or not." Roberts voice was a low snarl and Stacy cringed away from him. Stacy looked to Bob for support but he turned away from her with shame as she noticed his black eye. "That's right, I'm in charge now." Roberts laugh was ugly and frightening.

*...in charge now...* Amandas chest burned as her breathing continued to accelerate. Her eyes flickered as she tried to regain consiousness. What was happening to her? Why was she so turned on?

Amanda moaned out loud and Stacy turned to look at her as Robert clamped his hand painfully on her jaw and forced her head back to look at him. "Look at me when I'm fucking talking to you." Robert barked. He was reveling in his new strength and power and by the looks of things he had stopped Amanda from using the gun on herself, if she had someone would be growing by now. He glanced over his shoulder at Amandas huddled form, she was hyperventilating like crazy from what little he could see but she didn't look any bigger. He turned back to his mom. "Things are going to be different around here from now on," he grinned even wider at the obvious fear in his mother’s eyes. He could smell her fear like an animal and it made him feel even more empowered, even more in control.

Behind the couch Amanda’s eyes flickered open and closed again. *... Things are going to be different...* Her heart was hammering so hard in her chest it was making her whole body shake. Her lips curled back as she painfully grit her teeth with the building tension.

"Robert," Bob cleared his throat and stepped forward, trying to wedge himself between his son and his wife. "Robert you cannot talk to your mother that way, we have to sit down and talk about this like civilized..." Bob's words were cut off as Robert clamped a hand around his father’s throat and squeezed. "Dad, why do you even think growing a backbone now is going to help you? We do need to talk and it's going to be on my terms."

*...my terms...* The ache in Amanda’s body increased a hundredfold as every bone in her body stretched and thickened to support the rest of the impending changes. Her curled up legs pushed against the couch and it rubbed against the hardwood floor with a squeak as her expanding frame slowly pushed it aside. Her eyes flickered again as her breathing and heartbeat unbelievably sped up even more. She was literally vibrating from the action.

Robert brought his parents heads side-by-side, chuckling to himself at how easy they were to control. This was seriously turning him on. The power, the control. His tighty whities were fighting a losing battle against the strain they were under. Robert wished there were other chicks around right now besides his mom and sister, he would have to go find one and take her as soon as he finished teaching his parents a lesson here. "First of all if either one of you even thinks about calling the police about this I will hurt you. I will hurt you like you've never been hurt before and there is not a thing you can do to stop it. Either of you, both of you. It doesn't matter, look at me!!!" An odd squeak caused Robert to stop gloating and turn to see what was going on behind him. Amandas quivering back could be seen hunched behind the couch, something was pushing the couch slowly across the floor and the wood back against the hardwood floor squeaked loudly again.

*...hurt you like you've never been hurt before...* Amandas eyes snapped open and she gasped, suddenly able to catch her breath. She slowly struggled to her feet and tried hard to focus through the haze her mind was in.

"Oh my God..." Stacy said softly as Amanda rose slowly from behind the couch. Her daughter was skeletally thin and freakishly tall. "What is happening here?" She whined with fear and pain as Roberts clenched her jaw even tighter.

Amanda put a hand to her chest and turned towards the sound of her mothers voice, her vision swam and she put a hand against the wall to steady herself. Her heart was beating slow and strong and the sound of the blood rushing past her ears was deafening.

Robert dropped his parents and clenched his fists as he turned to Amanda. "Shit," he breathed. The gun had hit Amanda after all, but she was just tall. She must have forgotten to turn up the muscle setting. He would have to finish slapping some sense into the bitch. He hesitated just a second as he realized that her head was brushing the top of the vaulted ceiling, the arch went from something like 12 feet at the walls and just over 15 in the middle of the room. She was at least 13 feet tall he guestimated as he took a step forward.

Amanda moaned and shook her head. She was overwhelmed with feelings. Feelings of extreme horniness, feelings of confusion, anger, and something else, something amazing.

Robert took a step towards his sister with clenched fist and stumbled as his father did the best he could to tackle his muscle-bound son. "Leave her alone!" Robert laughed and easily shook his father off. When he turned back to his tall skinny sister she didn't look as skinny anymore.

"Shit," Robert breathed again. Stacy fell to her knees, her mouth hanging open. What was happening to her family? What was going on? Amandas clothes had been stretched tightly across her tall gangly body but now they were looking like they were painted on. The button on Amandas jean shorts popped as her hips expanded, shooting across the room hard enough to punch a hole in the plaster wall with another puff of dust. The zipper growled as the teeth pulled apart, the sound mixed with the deeper tone of the heavy denim fabric tearing away from her legs as they grew thicker and thicker.

Robert stopped in his tracks, trying to stop staring at his sisters changing body. His briefs tore completely as his aroused member became fully engorged. He shook his head and tried to stop the thoughts he was having as her body filled out with VERY womanly curves.

The cups of Amandas bra were overflowing with generous handfuls of breast flesh she hadn't had just moments ago. The underwire was twisting at the pressure and the cups were splitting at the seams. Her nipples stood out like thumbs against the fabric of her t shirt which was pulled so tight it was all but see through. Finally the strip of fabric between the cups tore through with a snap and her rapidly growing breasts shook free. The t shirt tore right in half at the motion and Robert gasped as he saw the hard muscles forming on Amandas torso along with the enormous breasts. Her abs flanked her belly button like rows of paving stones and immense, vascular pectoral muscles were forming like armored plates behind her breasts, pushing them out even more dramatically.

Her shorts continued to tear away from her legs, which were changing from curvaceously sexy to shockingly thick and dramatically muscular. Her ass rounded and hardened, looking like twin cannonballs molded into feminine shape and grafted onto her wide hips. Tattered strips of panty fell away revealing her womanhood, which was just about eye level for everyone to see. From the immense thighs and wide, sexily proportioned hips her stomach narrowed to a dramatically muscled set of abs that were almost overshadowed by the breasts that were mind boggling in their size and ability to apparently ignore gravity. The last remnants of Amandas t shirt drifted softly to the floor, completely obliterated by the immensely thick arms and a gargantuan shoulder span. Amanda clenched and unclenched her fists. Her forearms, which looked about as thick as Roberts body bulged massively at the motion and the biceps that perched on her upper arms like small mountains jumped to attention and relaxed again. Amanda shook her head as though waking up from a dream. Slowly she flexed her arms, first one, then the other. The peaks were monstrous, the vascularity standing out from the biceps like a fireshose. She was massive, symmetrical, every inch of her body screamed power and sensuality and she was slowly but surely still growing even bigger. Roberts dick twitched and cum dribbled from the tip.

She grinned as Roberts eyes met hers. "I'll hurt you like you've never been hurt before," she repeated his earlier threat back to him and grinned even wider as he flinched away. "And put that puny thing away before I have to make fun of it," she jeered as she pointed at his erect member. She couldn't believe that just a few minutes ago she had been impressed with that thing.

She was going to have to find the gun again and get some guy to satisfy her ASAP. Or should she take care of punishing Robert first?

As Amanda glanced around the room for the gun Robert did the same thing, his mind racing for the one thing that might still be able to bail him out of this. Their eyes both saw it at the same time.
