When the massive muscle monsters finally came, they let out twin roars of rage and exultation, announcing their conquest of the ass they shared. They kissed vigorously, forgetting Chris for a moment as they drank in the bliss of orgasm, mashing his lithe, flexible body between their massively-muscled torsos. They filled him with copious amounts of cum; Chris' belly swelled with the stuff. And they kept going, kept fucking him, kept pumping their giant dicks into him, their minds overcome by the insanity of their lust, their bodies craving more and more stimulation, more and more sex, and ultimately more and more power. They wanted the world to bend to their will, and they would get it, too.
"Fuck, I'm still horny!" Jeff growled, throwing Dom onto his bed and straddling the much smaller man's muscular form, his gigantic dick and balls resting against Dom's chest. With his free hand, Jeff reached down and gripped Dom's enormous dick. He pumped it, then lifted himself up and pressed the big head to his well-lubed hole. He dropped down, taking the entire thing in one smooth motion. "Ohhh, yeah, that's it," Jeff moaned, feeling his insides being spread wide by the giant cock. "Now fuck me hard," he growled, his tone making it clear that this was an order. Dom growled in response and began to thrust.
The next morning, Jeff woke up late. He yawned and stretched, then got out of bed. He noticed the computer was still on and logged into the Chronivac, and a slow, wicked smile crept over his features. "You know what?" he murmured to himself. "Why not?" He walked over and sat down at the computer, clicking his way to the main screen for the program.
"Well," he thought out loud, "what's something interesting I can change? I should grow a little bit every day..." He started typing, then smiled and clicked the button to make his changes permanent. He stood up, stretching luxuriously, and then looked in the mirror. Sure enough, his body was slowly swelling up and out, getting taller and thicker and even more muscular. His height wasn't increasing noticeably at the moment, but his dick was: slowly growing, slowly lengthening, and slowly becoming even thicker than it was before. But his muscles were really the biggest change. They swelled and swelled, bulging out bigger and bigger and more defined by the minute, as the testosterone flowing through his system accelerated the growth of his cells, building more and more muscle. He hear that Dominic is calling him. He answered the phone, smirking to himself. "Yes?" he asked.
"I'm soooooo...... hungry," Dominic told him.
"Good. I'll be right there." Jeff hung up the phone and left his room, walking over to Dominic's.
Followed by the bass sounds and bed whistling Eric has entered the room. He saw the free chair near computer and he is going to finish what he wished yeaterday. He sat down and opened the Chronivac page he left open, he looked at the screen for a moment. Revenge is a dish which is best served cold, but it seems like my revenge will be served hot. Eric grinned and pressed a few buttons, then he hit enter and sat back. He waited for his plan to take effect.
"You're going to be a real monster, now," he whispered.
"That's right, you little size queen, and you're gonna love it!" Jeff and Dom were behind him because they want to change something too.
"I'm talking to myself, idiot" he answered.
"What did you say?" Jeff put his hand on the back of his neck and pushed his head down, while Dominic is going under his chair, grabbing his legs and spread them apart.
"Yeah, just like that," Dominic said, pushing his dick against Eric's ass.
They started to fuck Eric, as soon as Dominic penetrated him, Jeff did too.
After a few minutes their cum starts to fill Eric's body. But two strange things start to happen. With every onze of their semen inside Eric his body reply with growth and they do not fill that they are capable to stop. So they were cumming and cumming and Eric grow and grow. His body becomes bigger and bigger, his ass, his dick, his balls, his muscles. He outgrowhth Dominic and started to be close to Jeff when the changes stop.
"Holy shit!" Jeff gasped, staring at his massive friend. "You're so hot!"
"You're the hottest thing in the world, now!" Dom agreed.
Eric looked down at his new body. 7 feet and 800 pounds of muscles. "Oh, yeah. I'm the man!" he crowed. He lifted his arms and flexed his enormous muscles. "Now, how can I use this to my advantage?"
He grinned wickedly and stood up. I guess I have to grow a little bit more. He touch Dominic's dick by hand and that stood on his knees. His tounge gently waves near the head and than he reach it as it was a refilling machine. He sucked and drank everything Dom was giving. When his balls are empty he try the same thing to Jeff. Now Eric thinks he was bigger than Jeff with his ability to grow without Chronivac control but this blowjob was his fatal mistake. Jeff don't want to be smaller than anyone and he used the time to make changes into their profiles. He wanted to outplay his brother and he make a wish about his own semen.
He allows Eric to do his blowjob and even grow but with every sip Jeff growth twice than Eric and after five minutes his size was 15 foot and 2 ton. His muscles was bulging and his dick was almost 40 inches. "Well, Eric, what do you think of this?" he asked.
"Now, that is a size." Eric said as he is licking his lips. "Can we fuck?"
"I have better idea. Come here." He sat down and put his legs out.
Dominic also does not want to be the smallest and quickly reachs Jeffs cock and start sucking.
"Yeah, I like that. Come on, suck my dick like a little slut." He push Dom's head against his cock and his brother's friend is deepthroating his giant monster. "How much you can take? Let me find out." He puts his hand on Dom's head and force him down, making sure that he cannot move. Dominic chokes and coughs but Jeff does not stop until his balls are pressed against his mouth. His cum filled Dominic's stomach and influences their both growing.
"You are my bitch. Do not forget." He pushes him down and starts walking away.
Dominic does not know what to do. He can't breath, he is filled with cum, his muscles and his cock grows, his mind is in the mist. Eric tried to fight, he is stronger and taller but he cannot stand against the size and power of the monster which Jeff has become. And Dominic was about to be bigger than Eric again. So Jeff is far away and his parameters become to be higher. He is 17 foot, 3000 pounds. They barely fit the room and with every sip of Jeffs cum they were about to destroy it.
"I'm a GOD!" he shouted, his voice shaking the very foundations of the house.
Eric was frighted and left the room. He tried to think what he can do and he understood that he has the only chance. To use Chronivac last time and change everything it deserves. And there should be only one true God. And this God should be him. He ran to Jeff's computer and started to type. I need more and after he press enter the giant hand fist him. Eric hit computer and destroy it with Chonivac. But his brother and friend will never know it because they destray the house.
When Eric opened his eyes he understand that it was not his brothers hand, it was Dominic. And even he was in the shadow of his brother. Jeff was 150 feet tall, 50 ton monster and his muscles is not possible to describe. Hah, I guess you didn't finish and now your are ours. They penetrate his mouth and ass again and start to blowing his body with their cum. It was the worst mistake. Yes, Jeff was growing but Eric was growing much faster. Even in a minute Dom filled that Eric is strangly heavy and he fall on the ground. Jeff opened his eyes and understood that Eric still shorter but just a little bit lower that his nipples. Jeff tried to step out but Eric smiled and asked " Where are you going my lovely brother?" and touched his cock. Jeff had no chance and started to cum again. Eric start to suck and their path of grow continued. Jeff was so high and lost in this feeling that he closed his eyes again and next time he opened it when something touched his face. It was a giant head of Eric's cock. His brother was about to fuck his mouth. "Come on, suck it like the little slut you are. Don't worry, I will grow you after me and than we can fuck each other forever. You are mine, you are our toy and you will always be." Eric stayed 270 feet, 120 tons. Jeff was 250 feet, 50 tons and Dominic was 165 feet, 650 pounds. Someone might think that the planet was in a trouble but Chronivac changed everything in the way to keep everything safe and ... interesting.
"I am a god!" he repeated, laughing maniacally as he stroked his immense dick, watching the two smaller men worship his gigantic frame. "I'm bigger and stronger than you, and now I can grow, and cum, whenever I want!
