The door was flung open.
"JEFF!" Derek's voice booms. The giant beast of a bodybuilder looked like an angry bear as he glared at his son, his hands on his hips, his cock hanging heavily between his legs, almost touching the ground.
"Yeah, dad?" the teen grunted, his fingers barely able to wrap around his gargantuan, 14" dick.
"It's time for your daily workout. Get up," Derek orders, the huge, hairy, musclebound man turned father looking like a titanic, Greek god of old, a perfect specimen.
"Alright, I'll be down soon, dad," Jeff said, the 16 year old getting to his feet, his legs wobbling under the weight of his own massive, beefy frame.
"You better be," Derek growled. "You know how hard it is for me to keep that thing down, right? You're making us late for our meet with Elias' coach, kid."
"Sorry, dad," the boy grunted as he began to pull out his workout clothes, a tank top, and gym shorts, the former having a special hole to allow his cock to stick out.
"You should be," the man grunted. "We'll need a good warm up before the competition. It's going to be a tight one, but I think you're ready."
Jeff chuckled, "Yeah, we'll show those wimps what we can do."
"That's the spirit, son," the beastly man said. "I'll see you downstairs."
Derek left the room, leaving Jeff with the daunting task of dressing himself. It was hard enough before, but now, his arms were so thick, his biceps the size of a basketball, his legs the girth of a tree, it was a task to put on the tank top, and the gym shorts were a feat in themselves.
Finally, he was dressed. He was a huge, musclebound stud, 7' tall, 450lbs.
He lumbered down the stairs, his heavy steps causing the whole house to shake. He reached the living room and was met by two huge, hairy, musclebound brutes. They were his dads, they were 11'5'' tall, and a little over 1200lbs each.
"Alright, son, let's get to work," Derek ordered, the huge muscle beast towering over the teen.
"Yes, sir," Jeff said, gulping as he took in the sight of the two giants, the tops of their heads reaching up to his nipples.
"Don't worry, kid, you'll get there," Elias chuckled, his voice a deep, resonating bass.
The three muscle giants made their way to the garage. A giant, custom-made SUV was waiting for them, with two extra seats added for the two fathers, and the third one for their son. They squeezed into the car, and began the trip to the gym.
Jeff was amazed by the power his body had. His huge cock throbbed between his legs. The boy was in a trance, his mind still trying to catch up with the changes the Chronivac had wrought.
His dads were giants, and he was a muscle freak.
"Hey, kid, snap out of it," Derek barked. "We're here."
The three giants stepped out of the car, and headed into the gym.
They were met by Elias' coach, a small, lean man.
"Hi, guys," he greeted.
"Hi, Steve," Jeff said, his voice a deep rumble.
"Good," the coach said.
"Let's get started," Derek said.
They walked into the gym, and the sight was amazing. The gym was filled with muscle monsters, each of them a hulking mass of muscle and hair.
Derek and Elias went to the weights section, and Jeff joined them. The three muscle heads pumped iron, and the sound was deafening.
The three giants bench pressed hundreds of pounds, and the sight was breathtaking. Their muscles bulged and rippled, and their bodies were covered in a thick layer of sweat.
"You're doing great, guys," the coach said. "Keep it up."
After a few hours of intense training, the three giants were spent.
The three muscle heads finished their workout, and then moved to the showers.
"Son, you're doing great," Derek said, as Jeff pumped the weights.
"Thanks, dad," the boy grunted.
"You're going to win the contest, no doubt," Elias said, his voice a deep rumble.
"I hope so," Jeff said, as he kept pumping.
"Don't worry, kid, you're the best," Derek said.
"Daaad, please, stop. I know that you want to support me but I know that I'm smaller than you were my age. You were 10' and weighed like 900 pounds and Elias was a little over 900. I'm just over 450!" Jeff said, the boy's voice strained.
"Jeff, look at you. You are a true muscle freak," the beastly man said.
"And, so am I," Jeff said. "I'm just a freak."
Jeff chase the first shower cabin and with that allowed his dads took their private time in the farrest section. The sound of wet smacking was audible all across the gym.
The road back were silant. No one talked. Jeff was too upset to say anything. After a dinner he went to his room. His dads let him have his peace, not wanting to pressure him.
But, Jeff had another idea in his mind.
"It's time to fix this!" the boy thought, as he made his way to the Chronivac. So, as their son he is smaller than they are, so...
