Jamie stood dumbfounded for a moment, when he suddenly felt a pressure in his head. He stumble slightly but steadied himself as he pressed a hand to his forehead.
"Daddy, are you ok?" a concerned Timmy asked.
"I- I'm not-" Jamie stammered out but found himself unable to utter the rest of his sentence as memories of a new reality poured into his head.
The events played almost like a movie in his mind's eye. Jamie was 29 years old. All his life he was a big and tall kid, and when he took up bodybuilding at 14 he grew like a weed. He swept every junior bodybuilding competition he entered throughout high school. He drew media attention for his impressive physique and record breaking size. Even as young as 16 he was featured on the cover of Muscle & Fitness. Already he was 6'8" and closing in on 300 lbs. He was disappointed he didn't meet his goal of passing 300 before the interview. Anyone who was anyone in the bodybuilding world knew him and feared the day he was able to join regular competitions.
And before long, that day came, and so Jamie's bodybuilding career continued in a whirlwind of media fame and endorsements and of course, non stop growth. Every year he put on size and he even went through a late growth spurt when he was 20 that shot him to his final height of 7'3". Much to Jamie's dismay, the added height made his proportions look leaner and smaller, and so he doubled down his efforts with great returns. At 22, 7'3", and 339 lbs of honed, shredded muscle, Jamie became the world's youngest Mr. Olympia. Everyone wanted to know where Jamie was going from there, but life had other plans and that's when Timmy happened.
The night of his Olympia victory, Jamie caught up with a female bodybuilding competitor who was in the audience and before he knew it they were fucking in his hotel room. They had taken all the right precautions but the condom broke and a month later she told Jamie she was pregnant.
Jamie spent the next 8 months trying his hardest to continue life as normal, but once the baby was born, she decided she never wanted to see Jamie or the baby again. Jamie debated giving the baby up for adoption but couldn't bring himself to do it, and so he welcomed Timmy into his life.
Jamie stepped out of the spotlight for a while to care for Timmy. Raising a baby proved a challenge and Jamie's bodybuilding fell by the wayside, though with his genes, even barely working out once a week meant he managed to maintain almost all his size and gained just the slightest bit of fat.
And so the last 7 years went by with Jamie being re-branded by the media The World's Biggest Dad and a lot of "Where are they now?" articles. But Jamie decided last year he was ready to get back in the competitive bodybuilding scene and so he resumed his training. He grew bigger and faster than ever and now here he was, at 383 lbs of pure competition ready prime muscle.
The movie of his life came to an end and when he opened his eyes his entire house looked different. It looked significantly more updated and upscale than before and all the ceilings and door frames were enlarged to accommodate his massive bulk. Another brief memory of having the home custom built with his Olympia winnings flashed across his mind.
As he looked around he realized he was standing in Timmy's room and he was snapped back to reality by Timmy's voice below him.
"Daddy! Daddy! Are you OK?" Timmy sounded distraught as he tugged at the towel around Jamie's waist.
Jamie bent over to crane his neck over his pec shelf and saw Timmy, but not quite the same Timmy from before.
Timmy had the same blonde features and cherubic face, but he was taller. Much taller than the average 7 year old, at around 4'6". His body also showed some faint signs of muscle development. As much as a 7 year old could have anyways. While he was too young to have developed any size, he was almost devoid of body fat despite his age and his small muscles were surprisingly defined.
No longer Jamie's brother, Timmy had inherited the genes of his humongous god of a dad and bodybuilding mom, and it showed. Jamie anticipated Timmy also becoming a great bodybuilder as he matured and developed.
Jamie bent down and lifted Timmy into his arms, not even noticing his weight.
"Yeah, I'm fine sport. Just a little dizzy is all. Why don't we go downstairs and get breakfast?"
"Yeah, breakfast!" Timmy giddily exclaimed.
