…to the living room, where the noise had come from the turned on tv, playing a disastrous football game that your dad hypothetically was watching. However, right now, he was slumped over in the couch up against the wall, snoring loudly with the tv-screen lighting his frame.
He was a massive man, old, but muscular and tall, with huge guns and an enormous muscle gut, that would have made for some deep-cut, shredded abs if he didn’t drink so much beer. His drooling face was not bad either for his age, having minimal wrinkles, defined cheekbones, a big, masculine chin, a stout nose all below lightly covered in rough, beard stumps while messy, shortcut, golden-brown chair covered the top of his head, he must had been a real himbo back in the day with that somewhat clue-less natural look he had.
And despite having added some weight he was strong, having solid, bulging pecs, whose chest chair could be seen from this more-than-usually widen collar. Wait, something seemed off as you inspected your old man. His feet looked bigger, stretching the fabric of his socks tightly, already a solid size 17 which was way larger than any in your family. His shirt seemed to have trouble too as his midriff seemed to slowly slide upwards with each snoring breath, exposing more and more of his beer belly.
It was then you heard the tear, one of your dad’s short sleeves had torn due to his muscular, meaty arms, and soon more followed, as you begin realizing how small the couch looked beneath your dad.
He was growing, getting bigger in his sleep, as this massive behemoth of a man began accumulating more mass which made the living room even smaller. Your dad snored as his shirt, socks and pants ripped off his growing body, his pecs and muscle gut bulging through the shirt until it got too much, his pants exploding off as his tree-log legs turning even denser and bigger, the couch groaning and creaking louder and louder as his broad, muscular back glided up against the wall and his legs slowly crept outwards, getting longer and bigger, his toes popping out of his tight socks as his widening feet split them in half.
He wiggled his growing toes as he kept on growing in his sleep, only his black, stretched-out underwear were left, where a big, meaty cock bulged and grew against the fabric, stretching it and stretching it with each growing second, until it finally snapped off and let your dad’s enormous, hairy balls and cock flop out between his spread out legs, giving them room to breathe and grow.
Your dad’s balls were getting massive, semen heavy and bloated, seemingly your dad was accumulating much more sperm now, reminding you that once you had been one of your dad’s sperm, swimming inside his big balls until he blew his load into your mother. Now, he was certainly capable of producing much more offspring, if there even was a woman who could take his giant, growing cock now.
The couch finally broke, which only seemed to mildly bother his sleep, letting your dad's body keeping on growing, as he filled more and more of the living room with his massive dad bod.
It was first when his head hit the ceiling and his foot broke the tv, that he woke up, looking to be 14 feet tall roughly, and his growth finally coming to an end, seemingly.
“Huh…” He boomed with sleepy eyes: “Hey! I was watching that.”
