The dictaphone

Kevin went back home, thoughtful, and sat on his bed to think about the past events with Kate. As he did, the bed creaked under his increased weight. But he didn't care that much, and just thought. Sex with Kate had been great. She had been his first, and quite a good partner for as long as he could tell. But not being able to fuck her anymore... it was quite a problem. And her breasts weren't big enough to allow her to tit-fuck him properly.

Well, he needed someone else. Someone bigger. More endowed.

Kevin checked the dozen of messages waiting for him on his phone. Girls all sending him pictures of themselves, hoping he'd be interested, but none of them were big enough for him now. What a waste! The past him would have been crazy for weeks just for one of those pictures. But now, he just didn't care. He was big, and deserved big.

The huge boy went to bed in his poor, weak bed, and the thing creaked loudly with each of his moves as he slept.

When he woke up, the bed feet broke brutally the second he stood in the bed.

"Okay..." grunted Kevin, realizing he was now just basically a pile of steel hard muscles piles on each other, with an impressive dick sprouting out of it. He only managed to pull some clothes on with difficulty, and his mother herself was just looking at him in awe as the huge boy walked to the breakfast table, barely looking at her, too busy thinking about how he could have proper sex now.

His mind was in conflict.

Just use the dictaphone and stop this! Stop this growth! a part of him wanted.
Stop this? Stopping to become stronger and more attractive? You always wanted this! answered another.
But if you don't stop, no girl will be big enough for you!
And how is making the girls feel small a bad thing? You could even grow one just for you...

He shook his head, and went for the bus, occupying the whole door of it as he climbed in the thing, the bus moving slightly as the impressive mass of muscles he was now got in. It was complete silence, and he could heard a fly. Kate wasn't on the bus today. He saw her walking with Josh, and growled. She just wasn't enough for him, and Josh was a loser running after such a weak girl. And not even caring about him. Kevin was pissed. Maybe it was frustration speaking, but he was pissed.

The girls could feel it, because none tried to approach him. They just carefully stayed at some distance, right with boys afraid of the nerd who turned into the school strongest boy.

When the bus dropped him at school, Clyde was here, once again, marveling at his new size.

"Kevin, you're huge!"
"Will you say it everyday?" sighed Kevin. "Tell me something I don't know."
"Hey, calm down man, it's just... you're growing bigger and bigger day after day. It's unusual to say the least!"
"Then don't make it sounds like a bad thing. I'm stronger and bigger than ever, you should just be happy for me." said Kevin, still pissed about everything and everyone.
"What? Don't go size crazy, dude! Don't become one of those morons proud of their bodies!"
"Seriously? Shut up, Clyde. At least, I have the means to be proud of my body. And I'm just growing bigger;"

Clyde was a bit surprised. Kevin had never been so mean before, all this was definitely changing him. Clyde went silent, but felt really bad about what was happening. Kevin walked into the corridors of the school, trying to forget his sexual frustration with power. He loved how girls were looking at him with pure lust, even if he couldn't fuck any of them, frustrating him even more. And he loved how the boys that used to torture him were afraid of his growth.

Which just made him want to grow bigger.

Then, at some corner, he met Vanessa Barnes.

The school biggest girl. 6'0, as everyone knew, and that's how he knew his body had stretched up, because he was eye-level with her. When he used to be 5'10. His muscles needed space to grow ever stronger. And a large pair of F cups everyone knew about. Maybe... maybe she was the last girl here he could fuck.

"Vanessa. How are you?" he asked with more confidence than he ever had. Now, he had a clear objective.
"Uh... Kevin that is?" the school queen said. "Fine... fine, yes, fine... you... you changed those last days, right?"

She was still the bitch she used to be, and her pride was preventing her from falling right in his arms. In public, she wanted to still look cool. But she had eyes on the boy's big muscles. Even if she pretended not to. But Kevin couldn't help but notice. Was it how it was for a girl when boys were trying to ogle her quietly?

But suddenly, a voice interrupted him. The school principal was here.

"Kevin! You must follow me."
"Why is that?" he barked back in a way he never used before with anyone. He felt too important to be bothered by puny men, especially right now.
"Mister, you will calm down and follow me. Everyone has been quite... worried about your recent development. Even your family, I just had them on the phone. We agreed to have you go through a full check up at the infirmary, so we'll make sure you're not in danger. Today is the day the doctor is here."

Kevin sighed loudly, bored. Who were they trying to fool? They just wanted to now if he wasn't a danger for THEM.

"I can chose someone to come with me at the infirmary then?" asked Kevin.
"Uh... sure? That's the rule, right." answered the principal a bit surprised.
"Vanessa then."

Vanessa was confused, but followed him. What was happening? Kevin and her went to the infirmary, where a doctor, the school nurse and the principal were waiting for him. Vanessa waited in a corner, while they made Kevin sit on a bed. The doctor took his stethoscope, asked Kevin to lift his shirt, making both the nurse and Vanessa blush as he revealed muscles looking like they were carved in rock, then the doctor after only a couple seconds of listening to his body, hit several times his stethoscope, tried again to put in on Kevin, only to stop, a hand on one of his own ears.

"A problem, doc?" asked the principal.
"I don't know... my stethoscope must go wrong... this is just too loud."
"Too loud?"
"Indeed." said the physician. "This, or this boy has lungs and a heart powerful enough to be used by a whale."

Kevin grinned. Yes, that was it. Sorry, doc. It fueled his pride.

"I need blood samples. Nurse?" asked the doctor.

The nurse went for Kevin's arm, the boy letting her do, but as the needle went for his skin... it broke.

"Uh? What's with the tools today?" asked the doctor. "Change the needle and go again!"

But the next needle broke just like the first. And the third and last one, bent right on Kevin's skin.

He wasn't just stronger in muscles. He was becoming stronger in all the ways he could, including the strength of his skin and body. He was becoming... superhuman.

But this, no one wanted to word it. The principal the doc and the nurse said they had to talk about the situation in the principal's office, and asked Kevin and Vanessa to wait here. Just like he hoped.

"Loved the show?" Kevin asked right at Vanessa.
"What?" she blushed. "You're... you're not that impressive, you know! Just because you're bigger than you used to..."

creak

Vanessa stopped. A tear on Kevin's tee had just appeared on his right sleeve. Bulging muscles were visible under.

"What?"
"Say it again." grinned Kevin.
"Say... what?"
"That I'm..; bigger."

creak

A tear appeared at his other sleeve. This morning, he could barely fit in his clothes. Now, he was growing too big for them.

"Ohmygod! You're bigger!"

creak!

His shirt ripped in the middle, a slow, long ripping sound as a growing tear revealed his pecs and abs line. Vanessa covered her mouth in shock.

"Bigger!" she said through her hands.

Creak!

His shoulders tore through the fabric, revealing themselves, enormous and harder than metal. Vanessa stood and closed on him.

"Bigger!" she repeated.

RRRRRRIIIIP!

The sides of his shirt ripped and now, he was more muscles than shirt on the outside. Vanessa was shaking with arousal.

"Oh God! So big!"

RIP! CREAK!

The enormous muscles blew their way out of the remnants of the shirt, now mostly tatters on the naked torso of the boy. Vanessa stood there, panting. Until a powerful, huge arm grabbed her and brought her to his lap. She didn't move, eyes lost on the bulging, growing muscles in front of her.

"I'm a growing boy, Barnes." Kevin said "With growing needs. So you can let me fuck you, or just walk away and have fun with some weaker, smaller dicked guy."

She took a second to realize how he was speaking to her, but too aroused to tell him to fuck off, she just went right for his mouth and kissed him, while her hand went to his jeans. A throbbing, 11'' erection welcomes her, and unable to believe it, she groaned in pain and pleasure as Kevin entered everything he could in her, stretching the school queen.

One week ago, she would have laughed at the nerd. One week later, she was a toy in her muscled arms barely able to take his enormous cock.

This thought made Kevin really, really proud. And as he was fucking the proud school queen like a doll, the girl all boys dreamed about, he grinned, giving everything he could in her, not even caring about the noise as the infirmary bed broke under their combined weights, not stopping them...
