CHAPTER ONE — Pills and Promises

The twins were inseparable.

 

Born just three minutes apart, Alexander and Kal had always been a pair—their small town used to joke they were clones, one just photocopied from the other. Same soft brown hair, same lean little arms and skinny knees, same quick, bright smiles. Wherever one went, the other followed.

By the time they were eight, they had the same favorite foods, same clothes, same everything. Two halves of one whole.

And their father loved that. Dr. Emmerich was a man of science, a quiet, focused type who spent most of his time in the basement lab when he wasn’t sitting at the breakfast table with his boys. He always told them how special they were.

“Identical twins,” he’d say, ruffling their hair. “A perfect genetic match. Rare and valuable.”

The boys would giggle, not really knowing what he meant, only that their dad’s eyes would go soft when he looked at them like that. Proud. Like they were his greatest invention.

It was around their ninth birthday when the “thyroid problem” came up.

“Nothing serious,” their father told them, voice calm, gentle. “But you both have a slight imbalance. It happens sometimes in boys your age. Easy to fix with a little medication.”

He showed them the bottles himself, their names written neatly on the labels. One marked ALEXANDER, the other KALVIN.

“Just one pill every morning after breakfast,” he said, setting the small white capsules out for them at the table. “You won’t even notice it. But it’ll keep you strong and healthy.”

They trusted him completely.

The routine started like that—every morning, two glasses of orange juice, two tiny pills. Alex would knock his back and grin. Kal would follow, feeling a little more grown-up for having a “condition” that needed medicine. The way their dad smiled at them afterward made it feel like something to be proud of.

No one knew, of course, that only one of those bottles contained the real formula.

Alex was swallowing down the first dose of a new hormone therapy—experimental, designed by his own father. A blend of anabolic compounds, growth hormone derivatives, androgen boosters. Carefully measured. Meticulously recorded.

Kal’s bottle was filled with sugar.

The boys grew up side by side, none the wiser.

The boys didn’t question it. They kept sharing clothes, wrestling on the living room floor, trading off who got the top bunk. They were best friends, brothers, reflections.

But every night, after the boys were asleep, Dr. Emmerich was downstairs in the lab, entering data, adjusting formulas. Watching. Waiting.

 

This sounds promising ☺️. can't wait to read more

Like the premise of this!

 

CHAPTER TWO — First Threads Pull

It wasn’t until they were eighteen that Kal noticed the shirt.

It was one of their favorite t-shirts, the black one with the neon green stripes down the sleeves. They’d shared it for years, tossing it back and forth between their laundry baskets, never caring who wore it last. Same body, same size—what did it matter?

But this time, when Kal slipped it on, something felt… off.

The collar hung a little loose around his neck. The sleeves dangled just a bit lower on his arms, not snug like he remembered. He frowned, tugging at the hem, and thought maybe the fabric was just getting old, stretched out from too many washes.

Then Alex walked into the room, towel around his neck, hair still damp from the shower.

“Hey, where’d you find that shirt? I was looking for it.”

Kal shrugged. “It was in my basket. Fits weird, though.”

Alex grinned, stepping closer. “Lemme see.”

Without waiting, he tugged the shirt off Kal and pulled it down over his own head. The fabric that had sagged on Kal hugged Alex’s chest, the sleeves riding up just enough to show the soft curve of a growing bicep. The shirt didn’t hang—it clung. Tight across the shoulders. The stripes on the sleeves bowed outward, stretched by the shape of his arms.

Kal stared for a moment, blinking.

Alex looked down at himself, giving a little smirk. “Fits fine to me.”

Kal laughed it off, tossing him the towel. “Whatever, dude. Guess I’m just shrinking.”

But later that night, standing in the bathroom brushing his teeth, Kal caught a glimpse of the two of them in the mirror. Same faces. Same hair. But when Alex raised his arms to run the towel through his hair, the muscle underneath shifted differently—thicker, heavier. Kal’s eyes dropped to his own arms, still narrow, still soft.

Weird.

But… it was probably nothing. Right?

At least, that’s what he told himself.

 

In a few weeks time, there were other signs.

Alex’s voice started dipping lower, the crack of puberty making his words wobble until they settled into a deeper, smoother tone. Kal’s voice still jumped unpredictably, high one day, breaking into a squeak the next.

It wasn’t just the voice.

There were mornings when Kal would wake up late, stumble out to the kitchen, and catch Alex at the fridge, already halfway through a plate of eggs and toast, flexing absentmindedly as he reached for the peanut butter. The way his triceps cut clean lines down his arms, the soft shadow of something thickening across his chest.

“Hungry today,” Kal would joke.

Alex would just grin, shoving another bite of toast into his mouth, like he didn’t even notice.

Their dad kept the pills coming, same as always. Two bottles, side by side on the counter.

Kal took his every morning. Never missed a dose.

He had no idea.

 

The big blow came one Saturday at the beach.

Their friends were already down by the water, kicking up sand, and Kal was wrestling with the drawstring on his swim trunks when Alex stepped out of the bathroom.

Kal froze.

The trunks Alex wore—tight, snug against his thighs—used to fit both of them perfectly. But on Alex, they looked… different. His quads pushed against the fabric, thick lines where muscle wrapped around bone, stretching the seams to their limit. His waist stayed lean, but the way the trunks curved around the swell of his glutes—Kal couldn’t unsee it.

And there, pressing forward between Alex’s legs, the bulge of his growing manhood—undeniable, heavy.

Kal swallowed hard, looking away fast, heart thumping.

“Ready to go?” Alex asked casually, grabbing a towel and slinging it over his shoulder.

Kal just nodded, biting the inside of his cheek. For the first time, he felt smaller.

For the first time, he wondered if something was wrong with him.

So the mods on this site are really strict that all stories must be of characters 18 and up. Just saying you should head this warning before continuing

Hi @HandsomeLitleBoy yes like morphedmaverick mentioned, all content on this site has to be overage, no underage characters are allowed (it is one of the main rules here). Please change all age references in the story, or if you are not willing to do that the story will be removed.

Love this as a setup, but yeah. The characters need to be of age. Maybe make this their backstory and allude to it through dialogue or brief flashbacks? @Ceebrupt, does that comply with forum rules?

Yes, it sounds like it basically could pass the mod's test if it's shown as, say, talking about his childhood.  But I would think a change would still have to be made with such items as "And there, pressing forward between Alex’s legs, the bulge of his growing manhood—undeniable, heavy," when referring to an underage boy.

I mean nothing underage can involve growth or sexuality, and even flashbacks seem dicey I'll be honest.

@HandsomeLitleBoy If the story isn't changed over the weekend, it will be hidden.

I’ve changed the story. Is it okay now, let’s think of what remains as an intro? If not let’s delete this thread and Ill make a new one.

I don't understand why they changes those rules, it's not fair, it's a simple story, not a real movie

Good story

Cause for some reason its underage even if there is no sex. Theres other places you can post @HandsomeLitleBoy... Metabods allows these types of things if you chose to go there.

Could you maybe just change the reference to their ninth birthday, to maybe something more vague? Then it's all good

There was sexual content in the original version
