The dictaphone

When Kevin left Kate's home hours later, after lying to her parents about being here for some homework, the boy walked home with a stupid smile on his lips. He lost it when the sexual euphoria slowly fainted, allowing him to go back to reality. He had just fucked the girl his best friend was in love with! Crap! He had messed so much over there... and betrayed Josh's trust twice, Josh, the friend trusting him so much he had shared unlimited powers with him. He was such a bad friend to a guy like Josh...

But he could also remember the feeling of Kate against his body, her breasts, her fingers, her mouth... and how they fucked like rabbit. And how she couldn't believe how strong and endowed he was. He would have never dreamed of such a great, first time. And here he was, walking back home after doing it for real. Josh was a virgin, he knew it. Just like Clyde. And him, the nerdest of them all, was now the first one to have sex, and quite crazy one, with the girl Josh desired for so long.

Okay, maybe a part of him was proud. And enjoying this. He knew it was bad, but still, he couldn't help but feel good about some of this.

Kevin spent the end of the evening like this, shared between how good it had been, and how bad he had been to Josh. When he went to bed, he didn't even think about the growth. He was too busy thinking about his moral dilemma. And slept on it.

"No way!" he said as he woke up.

He wasn't just buffed now. He was obviously the kind of guy who spent all of his afternoon in a gym trying to grow bigger and bigger muscles. Those were larger and rounder than before, and as he flexed, a biceps as big as half a melon greeted him. He ran as fast as he could to take his breakfast and leave before his mother could see him.

As he stepped in the bus, the gazes on him were full of awe and respect. No jokes, no laughter, just some whispers, mostly between girls. His body and new looks were making quite their effect, and the boy was uncomfortable from all the attention he wasn't used to, even if deep inside of him, he loved it. Things went even stranger when Kate got in the bus and walked right to him, sitting next to the muscled boy.

"Hey, big boy! Tell me, did you hit the gym yesterday after we... worked?" she said in a whisper.
"No, why?"
"Sure? Your muscles looks... swollen. I mean, I got a close look yesterday, and I can definitely tell you're bigger... mind me checking this at my home after school?"

The boy couldn't believe his luck. He thought it had just been the craziness of a moment the day before but... the hottie was asking for more? He just nodded in awe, and as they arrived at school, pretending to pick up her backpack, Kate rubbed her boobs against him before leaving with a wink.

Kevin entered school, once again joined by Clyde and Josh, now looking at him in shock.

"Man, what's happening to you?" asked Clyde "This is more than just working out! You're visibly bigger than yesterday, and it's quite impressive!"
"I don't know" lied Kevin "I just... eeeerrr... react a lot to the gym. Body pumping with growth hormones and all, puberty... you know, weird times for a growing boy."
"Kevin's right." Josh said "This could be because of puberty but still... it's amazing! You're the school main topic of talks now."

School day went too slow for Kevin's taste. Each time he was looking at Josh, he felt bad, thinking about how he fucked Kate. And then, felt aroused because he knew he'd do it again in a couple hours.

And when this moment arrived, Kate didn't care about anything but going naked as fast as she could and being fucked once again. Still, she was looking at him in awe. "You're bigger!" she said between moans and grunts while he was making love to her. "Your body your... your cock, I can feel it! And god, you're looking good!"

At this moment, Kevin's mind was back to its primal state. He was fucking at hot girl, she was telling him he was big, and he felt desirable, powerful and strong, and only becoming more and more of those three things.And he loved it. For a second, he even wished it'd happen faster to him.

The next day, the scene repeated. Except it was a bodybuilder with a hot face looking like Kevin that got in the bus that morning. The boys were a bit intimidated, and jealous of this, while the girls were crossing their legs and rubbing them together. The boy was hot! Was the former nerd still single? At school, some of them found ridiculous reasons to give him their numbers, and Kevin received for various more ridiculous reasons pictures of the owner of the numbers, pretending to ask for his opinion, but just showing him pictures with them in nice dresses, or just with their boobs obviously visible.

And after school, Kevin would run to Kate's house, and fuck her till she couldn't take more. He loved her shocked face as she was repeating, unable to understand "You're bigger, Kevin! Bigger, I can't... I can't believe it but... please, go ooooon!"

The next day, the girls were in line in the bus to give him their numbers and a good look at the best cleavage they could show.

But none asked if they could sit next to him. Mostly because Kevin was so muscled his ridiculously large arms and torso were making him occupy a good part of the seat next to his own. He was a bit afraid by his own enormous body, but now, feeling the strength flowing in his flesh, the intimidated gazes of the boys he used to fear, and the lust of the girls.

"You should see a doc, man!" Clyde said. "This is some kind of sickness, no one can't just grow this fast!"

Kevin didn't say a single word, because he clearly heard the hint of fear in the boy's voice. Yes... from patronizing him, now he was a bit afraid. And even Josh was frowning.

"There's a natural explanation to this, Kevin, but you should stop hitting the gym and see a doctor, all this isn't really sane, you know..."

But still, he wouldn't think about the dictaphone. And would ask him if he had talked with Kate lately, and of course, if she talked about him.

Yeah, while I was fucking her doggy-style in her parents bedroom yesterday, you know. he thought with a grin. Before realizing how much of an asshole he was. Was this body corrupting him?

He thought about it only for a while, because it was soon time to go see Kate again. Except this time, Kate had to ask him to penetrate her gently, because he was really, really big now. She made a painful face as he did, but they fucked for a while. Until after a couple hours, she stopped him in the middle of the act.

"Kevin... Kevin, please, you're stretching me."
"Yeah, say it again!" he answered, as she had already said it several times, and now, thinking if Josh ever slept with her, he'd find her quite stretched, it was making it all better. Bad thoughts were arousing.
"No, I mean... get out, you're too big, it's like... like you grew in me, please, get out slowly!"

The boy was a bit surprised, but obeyed. Neither him nor Kate believed how long he needed to fully get out of her. Kate decided she could finish him with a handjob, and as she did, she was sure the boy was sporting a cock longer than 10'' now. She looked at the pile of muscles grunting behind the cock.

"Okay, let's try again. Slowly, okay?"

But even if they tried for a while, Kevin never managed to get in her again. He was just too big.

And a part of him loved it.

"Uh... I guess that's over... for tonight." Kate said. Kevin and her dressed back without a word, not really sure about what it meant about the future, and parted, Kevin leaving to go home. On his way, he thought about it...
