Amanda looked at Robert, trying hard not to simply laugh out loud. His muscles were even smaller and weaker than hers once were. But her muscles…. They were now easily bigger than his used to be. Although she planned on making him stronger again if she could, she was definitely keeping her muscles. The feeling of power and strength was intoxicating. Glancing toward the front door, Amanda turned back to Robert.

“Look, if you want to remain hidden for now that’s OK. Can you walk back to the couch?”

Robert grimaced, adjusting to his new, weaker form.

“Yeah, I think so.”

Amanda nodded her head. “Good. Then just stay there and rest. Sharon and I can go upstairs.”

Resigned to his current fate, Robert shuffled over to the couch as Amanda bounded back up the stairs two at a time, her muscular form feeling light as a feather. She began to wonder just how strong she was.

Reaching the front door, she opened it quickly to see a slightly annoyed Sharon and her younger sister Becka.

“Sharon! Sorry for the delay, but as you can see, I had some other stuff to deal with.”

Sharon looked at Amanda quizzically, but quickly caught on. “What? Are those? My goodness!”

Amanda smiled and escorted the two girls in. Amanda simply nodded at Becka, knowing the reason she was tagging along.

Becka had authority issues. She had a tendency to push the limit of her parents rules and then some. She was also a frequent visitor to the principal’s office due to her mouth and attitude. And that same mouth got her in trouble with the older students. Most freshmen knew their place in the pecking order. Becka didn’t seem to care about the natural order or the consequences. Now she was forced to stay with with her stupid sister while Amanda and Sharon giggled, talked about boys and updated their My Space pages or whatever silly site they now used. Only now she saw an opportunity. If Amanda grew big muscles like that she had to know the secret. And when she did….

The three girls walked up the stairs to the second floor and into Amanda’s room. Sharon and Becka dropped their back packs, while Amanda began to pull the ruined t-shirt and blouse off of her pumped up muscular form. Sharon gasped, while Becka looked on with jealousy.

“Holy crap Amanda, your muscles are huge!” Sharon practically swooned.

Amanda giggled, flexing up her right arm into a rippling, softball sized bicep, bigger than any Sharon had seen before. Amanda’s chest plowed forward, backed with bulging pectorals and large, firm breasts. Her shoulders and back were obviously bigger and thicker too, giving her a curvy T shape that swept down to her narrow, 8-pack abs and back out to wide, strong thighs. Sharon walked over and began to probe Amanda’s muscles, growing wide eyed at how hard they were even as she squeezed down. While she was rubbing her hands over Amanda’s pumped up form, Amanda explained the situation. Sharon shook her head with continued disbelief.

“And you got this big just by firing that gun? And what about your curves? You’re as busty as any girl in school. This whole thing hardly seems possible.”

Amanda shrugged her large shoulders. “I know. It’s like it not just made me more muscular, but more feminine too!” Pausing, her mouth curved into a rye smile. “So uh, what would you like to do?” Her eyes lit up. “Want to try it out?”

Sharon was still in thought, trying to figure out what to do next.

“No, not yet anyway. We need to run some tests first. For example, how do you feel?”

Bouncing on her toes, Amanda legs surged forward with muscles as big as an Olympic sprinter, but more defined. “I feel light, even though I know I must weight a ton. And I feel so strong too.”

Sharon looked around. “Why don’t you try and lift something. You know, something heavy.”

Amanda’s eyes settled on her pirate chest, which over time had become more of a junk box. By itself it was heavier than she could lift on her own. Now that it was full, it would take at least two strong men to lift it. Walking over confidently, Amanda leaned down, gripping the handle on one side. And with narry a tug, the side moved up. Smiling and letting out a confident grunt, Amanda pulled her other hand under the chest and lifted the dead weight above her head, using the other hand only for balance.

“I’d say lifting this chest with one arm proves how strong I am!”

Sharon shook her head with admiration. “That thing must weigh 250 pounds! I’d be willing to bet that you’re stronger than even your muscle size would lead someone to believe. This is remarkable!”

Placing the chest back down and reaching into her closet for the oversized t-shirt she used for a night gown, Amanda sighed.

“So what do you suggest? Try the gun again or wait?”

Sharon twisted her long brown hair. “Well, perhaps we could do a test to see how far the effect is. That is as long as you don’t mind risking growing even bigger.”

Amanda smiled. “Sure! But we should only run tests on me and leave poor Robert alone for now.”

Sharon laughed. “Ha! I’d love to get a look at him. He turned into such an ass. But you’re right. No reason to punish him any further.”

Becka remained silent. So Robert was a puny shrimp now was he? This could prove to be an interesting day after all. And once she got her hands on that gun, things would definitely be different. She just had to bide her time.

Sharon grabbed the gun and headed for the door. “OK Amanda. You stay here and I’ll go back to the front door. I’ll fire the gun into the air and see what happens.”

Amanda nodded her head as she struggled to pull the large shirt over her muscular frame. As she brought her meaty arms through the sleeves she looked ahead as Sharon left. Perhaps she should have left the t-shirt off. Becka stayed in her corner, sitting at the desk near the bedroom door, trying to remain calm.

Sharon reached the front entrance and pointed the gun into the air. “Ready?’

Amanda swallowed, both excited and nervous. “Ready!”

Sharon fired the gun for just a moment and released the trigger. But once again the aim didn’t seem to matter. Amanda began to swell slightly, her already large form adding additional inches in seemingly all the right places. Her chest and back swelled bigger, pressing her nipples hard into the material, forming a line between them on her Minnie Mouse shirt. Her legs bulged out further, as big as a Ms. Olympia contestant. Her unflexed arms pressed hard against sleeves that just last night were laughingly loose. Flush with a renewed sense of strength and weightlessness, Amanda yelled back out.

“Nope! Still too close! I’m even bigger now!”

Sharon pulled the gun to her side and looked toward the basement stairs. “OK! I’m heading down to the basement.”

Walking down slowly, Sharon could hardly wait to see Robert. Turning from the hallway, she pulled in a laugh, but was still smiling from ear to ear. “Hi Robert. Uh, how are you?”

Robert turned red from both embarrassment and anger. “How do you think I am? Just look at me?”

Sharon felt a pang of sorrow. He may have become a jerk, but he really didn’t deserve this. “Don’t worry. We’re running some tests. Hopefully we can figure this thing out and bring you back to normal.”

Looking down, he sighed. “Uh, sure. OK, thanks.”

Sharon pulled the gun up and pointed in toward Robert, causing his eyes to widen with fear.

“No! Don’t! Please!”

Sharon’s expression changed to surprise as she quickly realized her error. “Oh! No! I’ve got it on muscle growth. I’m seeing how far away the gun has any effect.”

Letting out a sigh of relief, Robert tried to calm himself. “OK! Right.”

Nodding her head, Sharon fired the gun. Robert sat up straight, holding out hope that the gun would now allow him to grow bigger. Unfortunately for him, nothing happened. Sharon shrugged her shoulders and headed back upstairs quickly, yelling at Amanda.

“How about now? Did you grow again?”

Amanda looked at herself, not feeling any different. “No! No change!”

Sharon entered the bedroom, a bit out of breath. “Well OK. We seem to have established a distance limit. But we still have the time thing to deal with.”

Amanda looked at Sharon and down to the gun. “So what do you want to do then?”
