My Daddy wasn’t with us for long; me and my Pa said goodbye to him just after my 9th birthday.

We had a lot of fun times, despite me only being adopted by the two men for less than a year. I didn’t realise it at first but it was soon way too quiet in the house.

One afternoon I had found my Daddy’s old chain necklace in one of the drawers. I can’t remember why I was looking for stuff, probably something for school.

He wore it everywhere and every day, I’d see it mixed up in the dark hair of his chest, glimmering in the sun. I don’t even know why he wasn’t buried wearing it but I guess that doesn’t matter now.

I felt a need to put it on, I didn’t even have to unclasp the back to slip it over my head.

All of a sudden I felt huge!

My legs got so big so fast I broke out of my shorts and underwear, then my stomach got big and wide too and it travelled up to my chest.

I never knew I could have a chest this big, but they inflated so huge and fat I couldn’t even see my feet afterward, and my nipples were big as well!

It wasn’t long before I could start to see something below my pec shelf, but curiosity quickly turned into surprise when I realised it was my dick! I was huge now, at least 9in for sure.

When the changes hit my shoulders I could feel it in my brain, like an itch being scratched as my mind was filled with new thoughts and memories. My Daddy has infused his soul with this necklace after dying and I was gonna be the new man of the house.

I grunted as my shoulders pushed sideways and packed on muscle, my arms throbbing as they grew huge along with my hands. A layer of fur started to grow that I was sure would thicken with time.

I’d aged a whole decade! Gone was the scrawny kid from before, replaced with a thick muscle jock that’ll show his Pa just what this new body could do!

Looking back in the mirror I saw what had happened to my face. My jaw was now much more square and covered in stubble. I looked down and smirked, snapping a pic to send to my Pa as he came home from work.

A little editing and a cheeky “Guess who?” Was all I needed for him to send me back a pic of his fat bulge.

Who knew; Daddy was a bottom.

When Coach asked Johnny Walker to take his keys and go to the locker room, he didn’t think anything of it.

Final period of the day and Johnny wasn’t exactly looking forward to more AP English, he took the lanyard of keys and whistles and went to the locker room as asked, unlocking the door and stepping inside. He saw nothing out of the ordinary, save for a strange cap sitting on one of the benches with a sticky note taped to it reading, “try me on.”

‘Is this a gift?’ Johnny asked himself, placing the lanyard over his head and approaching the lone hat. He tore off the note and looked inside for anything that may be a prank. Seeing nothing however, he placed it on his head.

Immediately things felt off.

Johnny’s head felt heavy and dizzy as he braved against the bench the hat was sitting on. He grit his teeth as his dizziness grew worse before subsiding. He pulled away, noticing himself in a nearby mirror. He didn’t look… correct. Normally his head would barely come above the bottom glass piece but this time half his head was too tall for it entirely.

He felt a surge of energy as his entire body now felt strange, not just his head. He sat down on a communal bench, unable to do anything except ride out the waves of pleasure and pain as his body grew and expanded. His arms hurt especially, bursting from his sleeves as they grew more and more and more, almost inhuman.

His pecs were next, pushing out like twin peaks as his nipples pressed against his shirt, screaming to be touched. Johnny let out a strangled moan as his abs popped into existence, four rows of hot slabs of muscle. One after another they cut and grew and swelled, making for excellent valleys and cum gutters.

Johnny’s legs were next, thick hairy thighs almost breaking his XXL shorts clean off as his calves followed suit and his feet tore open his shoes from the inside. He whimpered, the hair on his head growing out into a messy unkept cut instead of the nest trim he always had.

The door to the locker room opened suddenly, standing there was the Coach in all his masculine glory. “Damn boy, still not done? You must be resisting the changes then.” He remarks, making his way over to the helpless Johnny. “Come on son, you’re almost there. Just gotta let this last part happen; here, I’ll help.”

Coach’s big, warm hands came to cup and rub the boys bulge, coaxing small bursts of growth as Johnny’s face grew more rugged and angular, his neck thickening until his voice had dropped several octaves.

Coach carefully wove his fingers around Johnny’s waistbands and pulled the shorts and underwear down, revealing the little, leaking cock. He looks on with admiration as his lips made their way around the oozing head.

Johnny let out a grunt and groan as his instincts told him to buck wildly into the wet cavern. As he did, every thrust brought with it a new stage of growth, soon turning the small cock into a thick behemoth with bull balls to match.

Coach moaned and slurped on the appendage, drawing the memories of nerdy, scrawny Johnny into his overfilled balls and replacing them with being the hung assistant coach, Jonathan.

The newfound man bit his lip as his hands came down to push the older into his crotch, cock pulsing once, twice before unloading his thick spunk into Coach’s hungry maw. He looked down at the man, throat bulging out as his seed fills up his mouth before pulling out and spraying the excess on his face.

Jonathan smiled. “Heh, sorry coach. You know how I get when I’m horny.” He said. “Don’t worry though, I’m alright to teach the class now. You take a breather old man.”

When Brodie slipped on the amulet around his neck he didn’t know what awaited him. All he could do was fall to his knees as the surge of growth overtook his nerd body.

His pimply face changed into one of pure cockiness and masculinity, home was the double chin and replaced with a lantern jaw, perfect teeth and eyes that begged anyone looking at them to come to the bedroom.

His body inflated with hot muscle, pumping over and over again as his brain was filled with endorphins, not just giving him pleasure beyond belief but also draining any excess smarts and changing his brain chemistry around.

Finally, the amulet completed its purpose with changing up reality, making it so Brodie was never a nerdy slob. Anime posters and figurines that once lined the walls were replaced with weight kits and shelves full of protein powder. His discrete magazines changed from bouncing breasts to meaty cocks and tight bubble butts.

Brodie stood back up, the force of his transformation shredding his shirt in the process. He caught a glimpse of himself in the mirror, brain whirring before he let out a cocky grin. “Fuck bro, that pump was great!” He let out a flex and pose, one that kept the bros in the football team coming back for more. “Gotta text the bros, see if anyone wants to come by and -unf- suck my fat cock!”

His low grunts only grew as the front of his shorts pulsed and expanded, going from a measly two inches that blew after a minute, to an imposing 11in pole covered in veins with balls to match, able to go on for hours of relentless fucking.

Brodie looked over at a tripod, placing his phone in the stand and pressing the button for a delayed picture.

3…2…1…

“Fuck yeah!”
