This time it hits...Bob!

Both Robert and Amanda turn to see their father being hit by the bright green ray. Once again Bob is radiating out a green glow for the time the ray gun hits him. As soon as it stops, Bob collapses to the ground.

“Noooo!” shouts Robert, “that was supposed to be me!” He tried to leap for the ray gun that lay several feet away from the trio, but was held back by something. Or better yet, someone. Bob, conscious again, grabbed hold of his son’s leg as soon as he saw him make a run for the gun. Amanda was able to get the gun safely and held it away from her brother. She awaited what was about to happen to her father who just got hit with a second dose.

Robert looked down his leg to see his father laying on the ground, flat on his belly. His hand tightly gripped around Robert’s leg. His naked upper back looked impressive to his son, who had not yet had the time to see his father’s latest transformation.

Just as Robert was fixating his attention on his father’s back, who could swear he saw something moving.

The back muscles in Bob’s body were the first to react to the gun’s rays. They tensed and flexed, growing bigger by the second. Horrific noises of cracked bones accompanied the expanding behaviour of Bob’s body. The stare in Robert’s father’s eyes indicated that he was in a lot of pain, more than before. He let out a scream. Not only did his back muscles widen, his entire upper body was also being pushed up due to developing pectorals.

His thighs ripped off the khaki pants he was still wearing from his first transformation, this time not being able to withstand the new dimensions. A firm bubble butt was contained in tight white Calvin Klein briefs that were stretched to the limit. It was the only piece of clothing he was still wearing.

Finally his arms were in for a change. The hand that was still holding Robert’s foot was begin to grow. Robert could feel the increase of strength in his father’s hands by the sheer force of pressure he was applying. The biceps in his father’s arms grew to a respectable 20 inch, once again indicating that he was the real man of the house! His forearms thickened to Popeyesque proportions. It was a definite sign not to mess with this guy!

As Bob’s latest growth spurt came to a stop, he got up his feet. First on his knees, then throwing up his wide back to reach his full new height. His lats scrapped both sides of the doorframe he was standing in. Then his head bumped into the top of the doorframe, not uncommon for someone who is 7ft4. All the while keeping Robert in a firm grip close-by.

Bob looked his son in the eyes, facing down several inches, something he was not used to. His stare was comprised of anger, hatred and revenge. He could not control letting a slight smirk on his face.

“Well, well, well. Look who’s scared now, little shit! ‘too bad the ball’s back in my court again’ Well, guess again!” Bob mocked his son as he grabbed him by the side and lifted him up to his eye level. “So the secret’s out now. I now know why you were beginning to annoy me those last couple of weeks, punk. You secretly grew yourself bigger and bigger, slowly so no one would notice, and get a new attitude to go along with that body? An attitude in which your father has nothing to say, huh! Well, I have grown a new attitude as well, and I don’t think you’ll like it one bit!”

He placed his son back on the ground. “Now sit!” pointing at the couch. Robert couldn’t do a thing against his new pro-bodybuilder-like gigantic father. “Amanda honey, could you please pass me the gun?”

Amanda happily obliged. She enjoyed her new father; not only was she enjoying all the new muscles and strength that he was displaying openly in front of her eyes, but also the fact that he could finally show her brother what’s right.

Bob adjusted the dials on the gun, setting the muscle growth to -4 and the height to -2. Then he aimed and shot at his own son, sitting on the couch. “That will show you not to mess with your father!”

Robert, the last couple of weeks secretly enjoying his growing body, shrank back to his former self...and some more. His muscle disappeared completely, leaving a skinny 15-year-old in the couch, that was only 5ft3 and 102lbs. He was even smaller than Amanda now. He started crying.

“Ahh, who’s the big baby now?” Bob said mockingly “and now I want you to go to your room and don’t come down until you’ve figured out a way to repay me for the crap you’ve been put me through these last weeks. I’m thinking of something in the form of...uhm...a home gym, out of your allowance maybe? Well, at least you’ve got enough time to think about it!”

Bob grabbed his son, now weighing absolutely nothing to him, and placed him at the bottom of the stairs. “And go!” He didn’t know how fast he had to run up to his room.

Amanda, secretly enjoying the show, once again had the fullest attention of her father. “Wow dad, you really showed him! I’m glad I could help you out with teaching him a lesson!”

“Well thank you! You’ve really helped me change my life! I really don’t know how to ever repay you! This is exactly the body I have been dreaming about all..my..life!” Bob said as he let his pecs dance in rhythm to his words “Come here, I want to personally thank you!”

Amanda approached her over two-feet-taller father, who extended out his right arm in a flexed position. “Grab on!” Amanda grabbed the biceps with both hands as her father lifted her completely into the air, suspended only by his flexed arm. “Wow dad, this feels great! Your body rocks! And it feels like rock too! Man, I wonder what mom will say, or uncle Ben?”

“Yeah me too!” he said as he extended his other arm out. Amanda, like a monkey, swung to that arm. “No doubt she’ll like it!”

“OH...MY...GOD!! Bob, is that you? What happened to you?” a familiar voice said from the hallway.
