Becha was mad, very mad. Pissed even. Sharon shouldn't be stronger than her! SHE deserved all the power!
Seeing that Amanda had placed the gun in her lap, and was weakened by Sharon forcing her to continue holding the trigger, Becka made a quick dash at Amanda and snatches the gun away before she really can try and grab it back, even though Becka was still much stronger than her.
"If I can't use the growth on myself, then I'll just take away the strength from you!" yelled Becka, adjusting the gun to shrink at full power. She took careful aim, and pressed the trigger as hard as she could.
Only Sharon wasn't shrinking, and Becka couldn't let go of the trigger!
"I was hoping you would be that stupid LITTLE sister! You don't get it, do you? I've absorbed enough radiation so that anything your little toy does, makes me bigger, stronger, and more POWERFUL!" said Sharon as her muscles lit up even brighter than before, "YES! I can pull the strength even faster! By will alone!"
And the gun delivered! Even more power shot through the gun at a faster rate! Becka forced her eyes shut as Sharon was absorbing so much raw power that she was nearly blinding them!
"YES! MORE! I NEED IT!" screamed Sharon as Mother Nature began to cringe at her power as hurricane force winds blew around the basement, and lightning bolts shot everywhere, narrowly missing Amanda and Becka!
And as soon as it started, it was done. Sharon stopped pulling in more power, and allowed Becka to release the trigger.
"So do you get it now LITTLE sis, I'm going to always be stronger than you now, and don't you forget it." said Sharon, floating over to Becka, "But just to be sure, I'll give you the smallest possible sample of my power."
Sharon then took the gun from Becka, and handed it to Amanda, who stood in awe at Sharon. She had never dreamed that this little gun could make someone so strong...
Sharon then gently went to the ground, and picked up her younger sister with her pinky, and placed Becka on her bicep. Then tensing her arm and flexing, she quickly doubled her bicep, and then another flex put Becka through the ceiling and into the first floor! But another flex shoved Becka through the first floor, and nearly into the second! A final flex finally did it for Becka as she was practically thrown into the second floor, and nearly through the roof as she could handle no more, and passed out.
Releasing her monumental bicep like it was the most common thing in the world, the near-Goddess Sharon simply said, "Now then Amanda...what shall I do...
