-----------------------
Jeff groggily got up the next morning, moaning as he felt something in between his pecs. His eyes fluttered opened and his gaze was met with two mountains that jut out of his chest and a ridiculously thick one-eyed snake peeked his head just over the crest.
"Oh God!" Jeff moaned, his hands wrapping around his shaft, his arms heavy and bloated with muscle.
"What have I done?" the teen wondered as he began to pleasure his morning wood.
His thoughts were cut short however by a thunderous knocking at the door, "Jeff! What the fuck is all this?!?!?" a voice bellowed from the other side.
"Uh oh," the giant teen muttered.
The huge teen stumbled his way down the stairs, his body was massive, his arms and legs had thickened so much that the jeans and T-shirt he had been wearing the night before were little more than rags. His dads were sitting on the couch, looking up at him expectantly. There was a letter from the school on the coffee table in front of them.
"Care to explain?" the smaller of the two grunted, pointing at the paper. "You are the smallest in your class. The worst result at school competition!" Elias chest was heaving with barely suppressed rage.
"Uhh, yeah. I can explain..." the 7'2 tall teenager muttered.
"I'm too tired to listen it. Now you are going to the kitchen and eat everything Derek gives you. And you are grounded till the situation is changed!"
"But...," Jeff was silenced with a single look from the 8'4" mountain of muscles his father, Derek.
"Yes, Dad..."
------------------------
Jeff followed his dad to the kitchen. There were already two massive stacks of food piled high on plates. One, the regular stack, was for his dad, Elias. The other was twice as tall and was meant for him. The giant teen sat down in front of the meal.
"Dad, isn't it too much?"
"No, son. You are a big boy, you need big portions," his giant father growled, flexing his muscles.
Jeff exhaled and started to work with fork and knife.
-------------------------
Same time in Jeff's room. Derek was cleaning his room. When he dust the computer table, he touched the mouth and the screen showed him the Chronivac page, which Jeff left open. The giant of a man stared at it for a few minutes and then the idea was born. He turned on the machine.
"Let's see if the machine can make my boy stronger..." Derek mumbled, and pressed the start button.
The Chronivac was running, and Jeff was having breakfast, not knowing what happened in his room.
"Eat, Son. I'm going to do some exercises and will be back in half an hour. You are not going anywhere," his dad told him, and the 8'2" giant walked to the garden.
Derek's mind was spinning. If the Chronivac works, then his son will be stronger and will not have problems with his weight anymore. But would it do the same effect to him or his husband?
Jeff was in the middle of the meal, when Chronivac started to apply its magic. Slowly Jeff's frame started to grow.
"Oh no. Why it had to happen now? Oh shit"
Fork in his hand, which were small for the human his size, started to shrink. Plate and food on it was moving away. He was 7'8" and still growing. His mass was increasing. Muscles started to swell. They were stretching his skin, but it was not enough. His butt was moving away from the chair, and the backrest was pressing to his butt cheeks, making them to swell. He heard a cracking sound, the chair was about to split apart. Than he noticed that that room is expanding. The chairs and the table increased in size and thickness. He was able to sit comfortably. Now he was about 8'6'' feet. He wasn't able to see under his hairy muscled chest, but he knew that the food was somewhere there. His stomach, hided under the shreded cobled abs, growled. Jeff was hungry. He put a piece of chicken in his mouth and closed the eyes, because the feeling were so good. When he opened he was able to see the plate and food again, because now it was a mountain of food.
"Oh damn, I have a big appetite.," Jeff moaned and started to devour the food.
When he finished his breakfast the young titan stood up. His head was almost touching the ceiling. He went to his room to find out what is going on with Chronivac. On his way, he visited the bathroom to wash his hands. He saw his reflection in the mirror. His body was ripped and looked like the body of a true giant. His legs, his arms, his chest, all were bigger, heavier, and stronger. He could feel the power coursing through his veins. An enormous dick hung between his thighs. Its tip was visible under the lower edge of his eight-packed abs. Jeff moved his hand to touch his dick. It was so huge and heavy.
"Whoa, my cock is so amazing," the 8'8" teen titan was shocked. He counld not deny to pleasure himself and started to stroking his massive snake. The bathroom door opened. His dad Derek opened it.
"Hi, son," his dad's eyes were staring at his massive member. He licked his lips. "What are you doing here?"
"Uhh. Hi, dad," the teen stopped to jerk off and moved closer. Now Jeff was able to look into his dad's eyes. They were the same height right now!
"Can you help me with that, Dad?" Jeff asked blushing a bit.
Derek didn't wait any longer and put his huge hand on his son's meat. His hand could not close around the massive girth, and he could not cover the full length with his palm, so he helped with another hand. He was moving his hands faster and faster, Jeff was moaning and breathing harder and harder. "It feels so good, Dad. I'm cumming," Jeff's cock exploded. Semen flew everywhere, and the room was filled with a smell of cum.
Jeff's head touched the ceiling and his shoulder touched the walls. His mass was increasing rapidly. He was now 9'6" tall, and his cock was 3" longer and thicker. His chest and biceps were bulging. The hair on his chest, under pits and the bush between his legs became thicker and darker. His muscles were hard and covered with a layer of sweat. His glutes and lateralis were so developed, he was not able to walk like a normal man. He had to roll one leg around another to go forward, and his balls and cock were swinging back and forth. His cobra back was so wide that he was not able to keep his hands down, only 40-50 degrees. His ten-pack abs were defined and ripped. He could feel that the power in his body is growing, and his strength is increasing. Now he was looking to his dad downward.
Chronivac respond to this growth and everyroom and doorframe were adjusted to allow Jeff be able to use it. Of course, he had to bend his neck and turn his frame to go from one room to another, but it was an acceptable price.
Derek was happy that he helped his son. But the sight of his muscled body and the smell of his sperm made his cock hard. The older man had to adjust his pants and leave the room.
"I hope that the Chronivac will help me too," he thought, and left the bathroom.
