He's nearly 40 feet long

Your father is panting and moaning behind you as your ass is pelting by what felt like dozens of gallons of precum with every spurt. He is mumbling to himself enamored with his size as you struggle to get to your feet. Your massive body wobbles and jiggles as you finally plant your feet and really take in how sore your ass feels. It felt even worse than when Harry had grown. You stomp in place turning around and your eyes go wide at the mammoth cock and balls your father now has.

"Holy fuck, Dad," Your brother says for both of you. Your dad is rubbing the base of his cock and moans grinning from ear to ear. His balls take up half the living room and are being squished down by the ceiling that they had grown taller than. Your father had to be almost 40 feet away as there is no more space in the living room for anything else. His cock is nearly as tall as your ass explaining the pain in your hole stretching to take such a monster. Your father's feet no longer touch the ground. He is completely immobilized by how massive his cock is and he is already falling into the pit of lust as his cock spews pre all over you and your brother.

"I'm gonna cum, boys," he moans. "I'm gonna have such a massive cum shot!" He howls and the living room quickly gets flooded with hundreds of gallons of your dad's semen. You don't resist it. There's no point in it. There is no line your debauchery couldn't cross. You regularly get fucked by your brother, your dad isn't off limits either.

You charge is rampaging monster cock and push into it. Your belly oozes out to your sides as it gets squished by the monster that weighs so damn heavy. Your gut props it up a little arcing your father's tremendous cumshot toward the ceiling but more importantly, your face. You shove your head into his cock and begin guzzling. Your belly is full within moments as every rope of cum is enough to completely drown you in several feet of cum there is so much of it. You fill your own hole get filled once more and your body shudders in pleasure and excitement but you remain undeterred in your mission to drink as much cum of your fathers as you could.

The hours rolled by as your father's howls remained a constant in your home. Shouting, screaming, howling, moaning, groaning. He was drunk in euphoria and he loved every second of it. He humped his cock, tried grinding it against you. He licked it, kissed it, fornicated with it. It was everything he had ever wanted. Nothing was going to stop him from enjoying the manhood he now had.

Hours turned into days. Into weeks. Your dad's sensitive period had only just begun. For a few months, his cock will be in overdrive as his body adapts to such a massive extremity of pleasure. Harry had come to visit you concerned about why you weren't answering his texts, phone calls, or coming to school. He helped bring you some at-home work while you helped your father while also stopping by to rail you and add to the mess. You remember a doctor came and inspected your father and he was shocked by the massive growth. It was the biggest he had ever seen which only made your dad cum harder. By official measurements, your dad's cock is 38 feet long. It was just shy of 10 feet in diameter and was almost 32 feet around.

Your father was so proud. He had one of the largest manhoods in the world. A cock that would keep growing for the rest of his life.

After a couple of months, his sensitive period finally slowed to a crawl. He was obviously still incredibly horny and could cum at the drop of a pin. But, he was more in control of himself and could resist for a time. He laid on his back against his sweating musky balls huffing in his new masculine stench and was excited for his new life. Unfortunately, he was stuck in your living room as he would need to tear down walls to get out.

A fact your parents were already working on as your mother and him during his months-long lust-addled period as they had looked at new homes. Ones that could handle the three monstrosities you men had become. You stretched after your first day finally back to sleeping in your own room. The smell of breakfast hit your nostrils and like clockwork, you made your way inside. You stopped to admire the quaking cock and ball flesh that could all be seen in your spacious front window. You stepped inside and greeted your father as he laid back into his balls with his legs splayed out riding his cock on both sides.

"Morning, fatass," he said proudly as he sipped a beer and ate his omelets. His 38-foot cock throbbed and thudded against the ground sputtering pre and drooling gallons of it permanently. The entire living room and this section of the house were coated in pre and cum. You went to the kitchen and ate breakfast with your brother before having to get ready for your first day back at school.

"You mind giving your father a good morning fuck?" your dad asked you as you waddled by. You of course wouldn't say no as you shoved your ass against his cock popping his head and several feet of it in. "Oh, fuck yes." he moans as he orgasms. You thrust and stroke his cock with your ass as his hundreds of gallons of cum fill you up. Again and again, he orgasms howling and groaning in cataclysmic pleasure. The bulging of his cock as his massive balls pump hundreds and thousands of gallons of cum through it is mesmerizing and your father rubs his hands all over his cock worshipping it.

"Get going, IYNH," your mother says finding you still home. "You're going to be late. It's fine." You know what she means as she struts down the length of her husband's cock before climbing it and getting on top of your father. The making out starts and the moaning grows even louder as a rush of cum fills you before exploding out into the open room as you pull his cock out. You grab your things as your father's cock floods the home and you leave the front door open for the cum to pour out and escape. You wait in your yard for your ride and look into the window to see your mother undressed and having sex with your father the only way she can now on top of his monolithic genitals. Your father's monumental cumshot can be seen smashing into the wall at your front door splattering everywhere as it floods out and already covers half of your lawn and is quickly approaching your feet.

Your ride finally arrives before it floods the street however and you get loaded up to go to school.
