Part 1

“So, you’re telling me that this sonic wave makes you grow bigger?” I asked skeptically.

“Yep,” replied Jake, “It works by setting off a series of high frequency soundwaves that induces your brain to increase production of HGH—that’s human growth hormone.”

“Uh huh,” I said, still skeptical. Jake, my best friend, was always trying one harebrained scheme after another all throughout high school. We were just finishing up our first week of grade 12, sitting in my room after school, when he let this whopper out. I had hoped that he had outgrown these shenanigans. I was wrong.

“Seriously, Trevor, it works! It really works,” implored Jake, “Check it out.”

Even though we were alone in the room, I was shocked to see him whip off his pants right in front of me. Jake and I played hockey on the same team, so we’ve seen each other naked, but still, it just wasn’t proper!

“Jake, what the hell?” I cried out.

“Look, Trev! Look at my package!”

“I am NOT looking at your dick, man! Put that thing away!” I shielded my eyes with my hand, but not before I caught a glance. Damn Jake. I heard Jake sigh.

“I’m serious, Trevor,” he started in an exasperated voice, “I really got it to work this time.”

Getting over the shock, I moved my hand and opened my eyes. Jake was standing there with his pants down to his ankles…and sporting a huge schlong. I was speechless.

“See, I told you so,” said a self-satisfied Jake as he pulled his pants back up, “I’m almost 8.5 inches long now hard, and 6 inches around. I measured.” He would, too.

“How…how…?” I stammered.

“I have worked out a computer program to output a complex series of high frequency soundwaves, that, if heard in their entirety, induces your brain to produce growth hormones. The sound file is only a few seconds long. I listened to it every morning since early August, when I got it to work properly.”

I just stared with a confused look on my face. Science wasn’t my strong suit.

“Here, I made you a CD with the sound file,” he continued, “Just play it once a day and soon you’ll be producing hormones like crazy. I’m stronger, leaner, and even a little taller than before.”

I took the CD from Jake. Jake leaned in closer and whispered, “I also made a sound file for stoners. I tried it out on my brother, and it works. I’ve got a plan…”

I knew it was another of Jake’s harebrained schemes, but this time I listened with eager attention.

As part of the Student Council, I do the morning announcement over the school’s intercom and access to the soundroom. Jake’s plan was simple: Switch the CD with the national anthem with one with the national anthem AND Jake’s soundfile. We let it play for a few months, then switch it back. No one would be the wiser.

The switch was easy. All we had to do now was sit back, watch the stoners grow into hotties, and snag them with our own growing dynamite bods. Nothing could go wrong.


Part 2

It was the beginning of October and the beginning of a new better life for me. Jake’s soundfile was working miracles on my body. I had put on 10 lbs of muscle, grew half an inch taller, and two inches longer. I was sporting an impressive 8 inch dick of my own now, and was feeling incredibly confident.

Jake was still growing, too. He stood at an even six feet, two inches taller than me, and he tells me he’s up to 10 inches. He also said that his growth was slowing down as his body adjusts to the higher hormone levels. Which is fine with me—I wouldn’t want him getting too much bigger.

I winked at the group of stoners who walked past me in the hall, and saw them blush. Wow, were they looking hot—the soundfile was working it’s magic on them, too. All were supporting buff pecs and tight asses. The tall blond dude was sporting serious pecs. My dick stirred at the thought.

It was happening to all the stoners in the school, even the teachers. Many of the heavier ones dropped weight, and all of them were a little bit taller. Every one of them was about a ten pounds of muscle bigger, to boot. It also seemed that some were taking to the hormone levels more than others. Like James, for instance.

James was a friend of mine from elementary school, but we grew apart once high school came. He wasn’t very tall, only 5’8”, but he was lanky and cute and had a nice bubble butt. When this schoolyear started, we were surprised to find that we had lockers next to each other. I, for one, was pleased by this.

I was even more pleased a month later. James’s body was really taking to Jake’s treatment. He had grown a couple of inches taller, his shoulders had widened and his ass filled out his jeans nicely. His pecs, well, I had to force myself to stop staring at his pecs. They had grown from barely a flat chest to pushing out his shirt. I could see a thick slab of muscle bulge over the tops of his muscle tee.

“Hi Trev!” he said in his sweet voice, his large green eyes twinkling.

“Hi, James,” I said nervously. Even in my own improved bod, I was nervous. My hands shoke when I attempted to open my combination lock. It took me 3 tries. Stupid Trevor, bring yourself together man!

“You’re looking good,” he said, “Have you been working out?”

“No…I mean, yes, I have,” I hadn’t been. It was just the effects from the soundfile. I wasn’t going to tell James, though.

I happened to see Jake walking down the hall with a hot stoner on either arm. He winked at me and gave me a thumbs up.

Steadying myself with a deep breath, I blurted, “Jamesdoyouwanttogotothedancewithme?”

“Haha, what?” James said with a smirk.

That didn’t come out right. I took another breath, “James, do you want to go to the dance with me?” My body tensed with anticipation.

“I’d love to, Trev,” came his sweet, sweet reply. I let out a deep breath I didn’t realize I was holding in, “I have to go to class now, but, did you want to pick up some ice cream after school?”

“Yeah…” I said.

“Great! I’ll see you after classes!” he said as he bounded away with his friends. He turned his head to look back at me still standing at my locker. He smiled as I waved. His boyfriends giggled.

A loud bang snapped me out of my reverie.

“What the FUCK do you think you’re doing talkin’ to my guy?”

Fuck, it was Rick.

“He’s not your guy anymore, Rick,” I said much more bravely than I felt, “You broke up, remember?”

Rick banged the lockers again. A ham sized fist shook threateningly under my chin. I backed into the lockers.

“You stay away from him, you little squirt,” said Rick menacingly, “He’s mine.”

“Is there a problem, gentlemen?”

I saw Mr. Peterson standing behind Rick, his tall lanky frame towering over the two of us.

“No, Mr. Peterson,” Rick and I said in unison.

“Off to class, then,” Mr. Peterson continued, “I wouldn’t want to have to send you boys to detention for truancy.”

“Yes, Mr. Peterson,” Rick and I said.

I saw Rick flash an angry frown at me before we made our way down opposite ends of the hallway. What a fucking bastard.


Part 3

James and I went on several dates throughout October and we were having a blast. He and I really connected—it was like distance that formed between us the last couple of years had vanished. We went for ice cream, went rollerblading, and watched movies together—it was great.

His body continued to undergo changes. He was standing at 5’9”, his straight dark hair had growth to the middle of his back, and his muscles were lean and defined. He confided in me a week before the Fall Dance that he was wearing a XL shirts now.

“I don’t really know what’s going on,” he said, “It’s like everybody is going through a growth spurt at the same time! Did you know that Charlie is huge now? And that Ashley is almost 6 feet tall?”

“It is strange,” I said. It really was. I was almost 6 feet tall and sporting my own 10 inch erection now. Chiseled abs complemented cut pecs and solid biceps. I was 175lbs.

Jake was 6’3” and 195lbs. He was almost as big as Rick, now. He told me he had a 13 inch cock and that his balls had grown, too. I had asked him about the increased rate of growth.

“I don’t know, really,” he said, “Must be another growth spurt. It can’t last, though.” He didn’t look too concerned, so I let it drop.

Rick had asked James to the dance, and was incredibly angry when he found out I was taking him. Luckily Jake and I were hanging out that day, so he left me alone. He glares at me whenever he sees me in the halls.

It was Monday of the second week of November. The dance was two weeks away. Rick was growing more bold day by day—just last week he threatened to kick my ass if I took James to the dance. I told him to fuck off and walked away. It wasn’t easy turning my back on Rick’s 6’5” 230lb frame, even though I was catching up. He still scared the shit out of me.

I was distant and reserved on my date with James that night. We had a movie playing in my livingroom—my parents had gone out of town—although we weren’t really watching it. I wasn’t concentrating on our make-out session since my mind kept wandering to Rick. He was going to beat me to a pulp. James backed off.

“What is it, Trevor?” he asked.

I sighed, “It’s Rick. He’s planning to beat the shit out of me if I take you to the dance.”

“Forget about Rick, I can handle him,” James replied soothingly, “Tonight’s it’s about you and me. This is the first time we have been along togethim.” I caught the hint of anticipation on the edge of his voice. “I think you should be thinking about me.” He bit his lowerlip and looked up at me with his beautiful eyes. We kissed passionately. James’s hand rubbed my cock under my pants. His kiss increased in intensity as he felt it’s length stiffen and swell towards my knee.

“Look, Trevor,” said James as he leaned back and undid his shirt, “I’m outgrowing my muscle tee again.”

I was looking. Both the underside and topside of his muscle tee was overflowing with muscle. I stared hard as he reached around and undid the clasps. His pecs sprang free and rested heavily against his slim ribcage. He dropped the XL muscle tee to the ground.

I grabbed his pecs as he pushed me down onto the couch and kissed me. With one hand he undid my pants.

“I’m not the only one who’s been growing, I see,” he said breathily.

He worked my member free and slid down my body, his fat pecs sliding along my torso. His manly hand could barely encircle my girth. “Holy fuck, you’re huge.”

He lift his head 11 inches up and wrapped his lips around the head of my cock. Kneeling between my legs, one hand squeezing the base of my cock, the other stroking it’s length, James continued to suck me off.

Just as I was approaching a climax he stopped.

“No,” I cried weakly.

“Shhhh,” he said and climbed off the couch.

He slipped off his shirt, exposing his pecs to the firm flickering light of the TV screen. He stared into my eyes as he ran his hands along the side of his body to his jeans, and ever so slowly popped the button off. With deliberate motions, he inched his tight jeans to the floor and gently stepped out of them, long smooth legs glinting in the light. He wasn’t wearing any shorts.

“You like?” he asked in a sexy voice.

“I like.”

He smiled as he straddled me, his large pecs bouncing in the air. His nipples puckered.

I grabbed his right pec with one hand and put his fat nipple in my mouth. James gasped, “Oh, Trevor…”

With my left hand I traced his abs down to his waiting ass lips. Carefully spreading his plump lips apart, I placed my middle finger on his anus. James shuddered in pleasure. I worked my fingers inside his anus while I sucked on his pec, flicking his big nipple with my tongue. I could his arm slide next to mine and grasp my cock. He directed my cockhead to his ass lips. I withdrew my fingers from his hole and began working his anus.

He pushed himself down onto my shaft, his hot sex enveloping me. I could feel the walls of his ass stretch against the girth of my penis. He paused to let himself adjust to my size. I switched to his other pec and began sucking.

After a moment he pushed himself farther down my shaft, taking in 9 inches. “Oh god Trevor you fill me up…” Another push and his lips reach my base, my entire 11 inch cock inside of him, his firm ass resting on my thighs. “Yes, oh god yes…” Tears squeezed out of his closed eyes.

He lifted his hips high, almost to the point where my cockhead would pop out of him, and pushed himself down. Hard. He squeaked.

Again and again he rode my cock, it’s entire length glistening in his precum. His pecs bounded up and down on his body, slapping against his chest. My hands found his wide hips and squeezed.

We came together, me with a mighty roar and he with an ear-splitting scream. He lied panting on my chest. I could feel his hard pecs pressed up against me.


Part 4

The next morning before class I saw James run up to me at my locker, wearing his coat.

“Trevor, I got bigger,” he said simply. I blinked.

He took me to an isolated nook in the corner of the hallway. “I couldn’t fit into any of my undershirts this morning,” he said.

He opened his coat to show me. I could clearly make out both fat nipples pressing against the fabric of his shirt. His pecs were surprisingly perky given their size.

“I’m massive,” he whispered.

I felt my cock snake down my leg with a semi. Was he taller, too?

He went on his tiptoes and kissed me hard. “Last night was incredible, let’s do it again tonight.”

I had an incredibly hard time concentrating in class that day.

James and I had sex every night my parents were gone. He had gotten bigger, as it turned out, and continued to get bigger as the days wore on. By Thursday he was officially a XXL, and even that was beginning to show strain. He was standing at 5’10”. I wasn’t sure if he noticed, but I, too, grew bigger. I was now 6’1”, 190lbs, with an 11 1/2” erection. I think he noticed. I was pretty sure.

The nights were great, but the days grew tense. I worried about Jake. He missed the last week of school and wasn’t here again today. I had called his house and his mom said he was sick. He was at the hospital getting tests. I hoped it wasn’t serious.

I got a phone call on my cell at midnight that night.

“Trev, it’s me, Jake. Can you meet me in the park in 30 minutes?”

“Uh, yeah, sure,” I replied sleepily.

I threw on some boxerbriefs, being careful to tuck my flaccid 7 inch cock into a comfortable position, threw on some sweats and a shirt, grabbed my coat and crawled out my window.

I was waiting in the park, my breath clouding in the crisp night air, looking around for Jake. 35 minutes had passed since he called. I rubbed my hands together to warm them up. I noticed a large shape walk towards me from the shadows of the trees.

“Trev? It’s me, Jake,” I heard a deep voice say.

“Jake?” I said as the figure walked into the light of the lamppost.

I was astounded. Jake towered over me and his huge frame dwarfed my own. His coat barely covered his waist and even now and again I could make out thick ab muscles in the night. A massive bulge rested in the crotch of his too-small pants.

“Yeah, it’s me,” the deep voice rumbled.

“What happened?” I asked, with growing apprehension.

“It’s the soundfile, Trev,” said Jake, sitting heavily onto the nearby park bench. The bench groaned. “It fucked up my body. I’m a freak.” He sounded on the verge of tears.

I squeeze onto the bench next to Jake.

“I’m 7’2” now, Trev, and I’m built like a pro-bodybuilder on steroids,” he said, “My cock is almost two feet long.”

“It’s okay, Jake, it’s okay,” I offered.

“They’re sending me away for tests! I’m going to some special hospital in Houston for the next few months,” Jake yelled, shaking. I could see his massive muscles quivering under his jacket. “Stop listening to the CD, and take the one out of the school! Or everyone’s going to be a freak like me!”

He was visibly crying now.

“Do it, Trev, before it’s too late,” he said as he stood up. He began to walk towards his house, “I…I have to go now. Do it, Trev. You’ve got to stop it.” Long strides quickly took him out of sight.

I just sat on the bench, dumbfounded.

The next day at lunch I sought out Jake’s brother Mick. I found him sitting with his grade 10 friends in the back corner of the lunchroom. They all smiled at me when I approached and a more than a few showed off their generous muscles. Not one of them was less than huge.

Tearing my eyes away from one stoner’s beautiful melon pecs, I turned to Jake’s brother, “Mick, can I talk with you for a minute?”

“Sure thing, Trev,” he answered as he stood up.

I took a step back in surprise. He was two inches taller than me. His massive pecs strained at his tight shirt. Recovering quickly I lead him aside.

“What’s happened to Jake?” I inquired.

“We don’t know, but he’s huge now,” he answered, “They think the same thing is happening to me, whatever it is. Look!” He flexed his arms. Baseball sized biceps bulged under his longsleeved shirt. “I don’t care what it is, though. This is awesome!”

“Thanks, Mick,” I said with a look of worry. Jake was right, things were getting out of hand. I turned to leave.

Stars flooded my vision as I flew to the floor, my head bouncing off the tiles. My jaw ached.

“YOU FUCKER! YOU DID MY BOYFRIEND!” I heard Rick roar from what seemed like a great distance. He jumped me and started swinging. I was doing my best to fend off the blows but even with my improved physique, I couldn’t stop this ape.

Suddenly I felt Rick’s weight leave my chest.

“Get off of him, you bastard!” yelled Mick.

I sat up, bleeding from my lip, to see Rick on the ground, pinned by the gaggle of grade 10 stoners. I was shocked to see how well defined all of their muscles were as they strained to hold the giant down.

“You two, to the principal’s office. NOW!” Mr. Peterson pointed at me and Rick. We got up and stomped down the hall, glaring at each other. I wiped the blood off my chin.


Part 5

Suspended! I didn’t even DO anything! It was all that big ape! Fuckin’ Rick!

Being out of school meant not doing the morning announcement meant that the CD was still playing every day. And with my best friend halfway across the country, I didn’t know what to do.

James came to visit me the first night. It was nice seeing him again. He took care of me and fussed over my black eye. My other eye fussed over his tight shirt. I smirked.

“Yeah, get a good look now, because it’ll be a while until you see them again,” he taunted playfully. On top of the suspension, I was grounded. I wasn’t allowed out of the house until I went back to school, which was a week from now. My mom felt sorry for me, though, which was the only reason I got to see James tonight.

“Stupid Rick…” I grumbled.

“I’m so sorry, Trevor,” soothed James, “I told Ted we slept together, who told Ken who told Larry who told Tom who told Rick. I’m sorry.”

“It’s not not your fault, James,” I replied.

“James, it’s getting late,” I heard my mom from downstairs.

“Thank you Mrs. Swick!” James said back. He gave me a quick peck on the cheek, “I’ll see you in seven days.” My one good eye followed his ass as he left the room.

I stopped my daily listening of the CD immediately. Jake obviously stumbled upon something dangerous and paid the price. I had no desire to do the same. Even so, I continued to grow. I was 8” long when flaccid and 12 1/2” long and 9” around hard. I stood at 6’2” and just crested 200lbs. I cut an impressive figure in the mirror, with cut abs and solid pecs. I could barely enjoy it though.

I fretted over the stoners at the school. They were being subjected to another week’s worth of sonic treatment.

It was the Wednesday night before I went back to school. My parents gave me back my cell and phone priviledges and I was quick to dial James’s number.

“Trevor?” I heard him answer.

“Hi James,” I melted at the sound of his voice.

“Oh Trevor, thank god it’s you,” said James, “Something’s been going on this week and everybody’s starting to notice.”

I gulped.

“All the stoners are getting really…big…” continued James. Silence. “Even me,” he finished.

I gulped a second time.

“Trevor? Are you listening? I’m a XXXL now,” he whimpered into the phone, “My pecs are so huge and heavy. My mom is freaking out over my clothing expenses. I’m 5’11”. I grew 3 inches in a week! It’s crazy!”

I gulped a third time.


“James, I’ve got something to tell you…”

I filled him in on the whole harebrained tale.

“That’s why Jake is in the hospital? That’s why you’ve got…you’ve gotten bigger, too?” he asked.

“Yep,” I said simply.

“And that’s why all the stoners are getting so..such huge pecs? Charlie’s muscles are enormous! Mick is like 6’5”!”

“Yep,” I said sheepishly. It sounded really juvenile to hear it from him.

“And you hope that people will get back to normal once they stop hearing the sounds?”

“I hope,” I said uncertainly.

“Why aren’t the other guys growing?”

“Jake somehow had it tuned to stoners,” I answered.

There was a long silence.

“Have you stopped listening to the sounds?” he asked quietly.

“I have,” I replied.


’Oh?’ Did he sound disappointed? He might be. Rick used to be his boyfriend.


“Yes, Trevor?”

“Did you want me to get…bigger?”

“I would never force you to,” was his reply, “but…”

I could hear the implication in his voice. I smiled to myself.

I heard James giggle, “Goodnight Trevor.”

“Goodnight James.”

I popped in the CD.


Part 6

“So that’s what a XXXL looks like,” I said to James as he walked towards our lockers.

“I grew some more overnight.”

“Oh.” How was I supposed to know that? Still, he looked fabulous. His twin muscle pecs jutted proudly from his chest and shook mesmerizingly with every step he took. A slim waist flared out into the most curvaceous hips that banked an ass that just begged to be squeezed. His long glossy dark hair was drawn back in a ponytail, highlighting his high cheekbones and beautiful large green eyes. His manly thin lips smiled into mock amusement.

“Don’t worry, I just found that out, too,” he said. He threw his arms around me and kissed me with those firm lips. I felt his huge pecs press into me.

“I missed you,” I murmured.

“I missed you, too,” he whispered.

“I gotta run,” I said, reluctantly breaking away from his plush body, “I have to do the announcements, then switch out the CDs.”

I booked it down the hallway. My neck kept swivelling back and forth so much you’d think I was at a tennis match. All of the stoners were hot, huge muscled, and tall. More than a couple could look me straight in the eye, and a few even I had to look up to. The smallest pecs I saw were as big as cantaloupes and the biggest rivalled basketballs. Even though James was filling a XXXL muscle tee, he wasn’t the biggest. Several stoners had bigger pecs, especially those who had big muscles to begin with.

I walked into the soundroom and stopped.

“Trevor, we’ve got Harry doing the announcement this week,” said Mrs. Albright as he looked up and saw me standing at the door, “You can start again on Monday.”

“Ummm, okay,” I managed and left. Monday! Crap! That’s not good. ’Well, what’s the harm in two more days?’ I rationalized.

I got to my homeroom class just as Harry finished up. I heard the crackle from the loudspeaker as the anthem started up.

I was sitting myself down after the anthem when I noticed all the stoners in the class give a little shudder. I paused mid-sit and glanced at Charlie slumped in his chair next to me, his pecs resting on his desk. I could’ve sworn that I saw his huge muscles swell just then. I sat down completely.

I wasn’t dreaming. I took stealthy glances in Charlie’s direction every chance I got, and by the end of class I could tell that he had begun to stretch his shirt. A large ridge had formed where his muscle tee met his muscle and was clearly outlined in his tight shirt. His jeans looked tighter, too. All of the stoners in class fidgeted absentmindedly with their clothes the entire class.

By lunchtime, a third of the stoners at school had gone home ’sick.’ I wasn’t surprised. Half of them were bursting out of their shirts. In fact, a few stoners’ shirts did rip open, the stoners’ faces turning red as they bolted from the classroom. Many of those stoners remaining had just abandoned their shirts altogether, James among them. Nipples jutted out proudly no matter where you looked.

“My muscle tee was just getting too tight to be comfortable,” he said with a mouthful of fries, “I had to take it off.”

“I’m not complaining,” I said. Unsupported by a muscle tee, James’s big pecs hung lower on his chest but still sloped nearly a foot away from him. They practically rested on his lunch. He leaned over to get more fries.

“Oof!” he said. He grabbed his left pec in both hands and hefted its considerable weight onto the table. He did the same with his right pec, muscle overflowing his hands. “That’s better,” he said and grabbed more fries.

A lot of stoners were doing the same. Giant pecs rested on the tabletops all over the lunchroom, stoners happily munching their meals around them. All the guys were just staring, me included.

“I’ve noticed I’ve been way hungrier than usual,” said James, “It must be this ’growth spurt’ I’m going through.” He winked at me and had another bite of his double cheeseburger.

“Well, this ’growth spurt’ will have to end soon,” I said, as I saw a stoner stand up next to me. He was over six feet tall.

James sighed, “I know.” He leaned forward across the table and looked me in the eyes. His pecs flattened out across the tabletop. “Want to know what a XXXL pec feels like?” he whispered in my ear. I got rock hard in an instant.

James finished his burger and stood up, his pecs flexing unrestrained. Thumbsized nipples tented just on the underside of his huge pecs. I followed him out of the lunchroom, adjusting myself so that my cock was propped against my waistband. It stuck up past my own bellybutton. I stared hard at James’s round ass and the sides of his pecs, which I could see on either side of him. They bounced in time with his step.

He lead me to a small washroom on the fourth floor and locked the door behind him. He had a devilish look in his bright eyes.

Without saying a word, he reached under his pecs to grab his shirt and pulled it over his head. I was amazed to see a washboard stomach with a clearly defined six-pack on his slender waist. His arms were bigger than mine were when we started school, except his were lean, corded and cut. His back muscles were tensed supporting the weight of his pecs.

The large muscles hung in all their splendor. Fat nipples on coffeeplate sized areola cut into the coolish air as they puckered.

Deftly he undid his pants and pulled them off. Long legs that wouldn’t be out of place on an olympic gymnast managed to wrest my eyes from his pecs. They were still quite shapely. I watched his calves flex as he walked towards me, big pecs wobbling in the air.

He ran his manly hands along my shoulders and down my arms and reached below to lift off my shirt. I felt the cool air hit my chest. I flexed for his enjoyment. He cooed and ran his firm fingers under my pecs. He traced his fingers down between my abs and groped my cock, which was still sticking out from my waistband. He smiled with lust.

Next, with his free hand, he undid my pants and slid them along with my boxers to the floor. My poolball sized balls tensed in the cool air. He pressed his own body against my own, one arm around my neck, the other hand stroking my cock slowly.

“I think you’ve gotten bigger, Trevor,” he whispered in my ear.

We kissed passionately and I pushed him up against the wall. I felt his nails dig in to my shoulders as my own hands fondled his pecs. Their weight and suppleness drove me to the edge.

My hands found his ample hips and squeezed. I lifted him easily and poised his hot ass at the head of my foot long cock. He wrapped his long smooth legs around my torso. I thrusted him down onto my cock.

“Oh god Trevor oh god!”

I thrusted hard into him, banging against the wall in a fury. Both of his hands clawed into my back as he let out gasps of pleasure. I was buried to the hilt with each thrust—James took in all twelve and a half inches.

He came explosively on my cock and I came shortly after with a grunt.

We went back to class that afternoon sated and happy.


Part 7

I completely misjudged what harm two more days could do.

I was huge. I shouldn’t have let James talk me into listening to the CD again.

Measuring myself against the wall, I found myself to be 6’4”. I grew two inches overnight. I could feel my muscles flex powerfully every time I moved. I was 225lbs without an ounce of fat.

My morning wood suck out impressively into the air. Grabbing my tape measure, I measured it’s length: 14.25 inches. Wrapping it around the center of my shaft, I read the tape measure again: 9.75 inches. Holy crap.

Even my biggest clothes looked small. My t-shirt looked like a baby-t on me, all my bulging muscles clearly defined. I was as big as I wanted to get. James had come over last night and insisted I listen to the CD again. I gave in after a killer blowjob right here in my bedroom.

I pressed the eject button and grabbed the unmarked CD and threw it in the trash.

Half the stoners missed school that day. Another shudder went through the present affected student population after the anthem and another growth spurt followed. I had a hard time concentrating.

I didn’t see James at his locker this morning. I hoped he was okay. Today was the night of the Dance.

It turns out he was here today. He found me standing in line for food in the lunchroom. He snuck in behind me, his huge pecs pressing into my back. He whispered into my ear, “I’m wearing my XXXXL muscle tee.”

XXXXL?? I turned around. He was tall.

“Oh, and I’m 6’1” now,” he smiled coyly, “At least, I was before this morning’s anthem. I see you’ve grown, too.” He traced his hand along my arm.

We snuck off again to the fourth floor bathroom to have sex. James was quite impressed with my new physique, especially my 14 1/2 inch cock.

We went back to class that afternoon happy but far from sated.

“My older brother lent me his apartment for the weekend. We can hang out there after the dance,” James said with a wink as we walked into the school that night for the dance, hand in hand.

He was positively radiant in his tight backless sundress, every curve of his clearly outlined. I could see his back muscles flex carrying the weight of his huge muscless. He and I nearly stood eye to eye with him. I think he got a kick out of that.

I handed our tickets to the cute little grade 10 stoner manning the ticket booth. He had to reach around his huge pecs to put them in the envelope, six inches of firm muscle rippling with the effort. James smacked me lightly when he caught me staring. I smiled sheepishly while he just grinned and rolled his eyes. He squeezed his arms together on either side of his pecs, forcing nine inches of his own cleavage to swell.

We entered the gym to the principal just finishing a short speech.

“…and we will kick off the Fall Dance with a special request I received earlier today,” he said, “Have a good dance, everyone!”

He pressed play and I heard the first few bars begin to play.

“The anthem…?” I said incredulously, with a half-smirk.

“I talked the principal into playing it at the dance,” James smirked, looking at me coyly, “He thought it was very patriotic of me.”

“I bet,” was my sarcastic reply.

Just as the song finished a collective gasp was let out by all the stoners in the gym. James squeezed my hand, eyes wide and lips curling in pleasure. The fabric on his clothes grew taught as the growth spurt hit him.

Ten, then eleven inches of muscle flesh became visible as James’s pecs grew larger right in front of my eyes. His muscles tensed as they became larger and more defined, and his ass widened and filled out a few more inches. He actually laughed when he looked me straight in the eye and realized he didn’t have to look up to do it.

We danced the night away.

James wasted no time pushing me onto his brother’s vacant bed much later that evening. My discarded clothes left a trail from the apartment’s door to the bedroom. James, standing near the CD player, turned his back to me as he reached down and pulled his clothes over his head, the fabric clinging and stretching over his massive pecs the entire way. A black banana hammock was wedged between his tight ass cheeks and a taut muscle tee dug into his toned back. His pecs were spilling out of his now too-tight muscle tee and they sprang free with a heavy bounce when he finally ripped the shirt off.

James’s pecs stood out from his chest and capped with fat pink nipples that puckered in the air. They swayed mesmerizingly as he walked to the edge of the bed. My face was pressed between his firm pecs.

I felt the stangest chill shudder through my body as he pushed me on to my back and straddled my hips with his long legs. I felt infused with energy and power. I tore off his shorts in a frenzy and shoved a fat nipple into my mouth and sucked. Hard. James gasped.

Leaning back, he took both hands and guided my rock-hard cock into his waiting ass and pushed down. I could feel his tight lips stretch over the head of my cock as seven inches slipped inside of him. James’s nipple swelled in my mouth.

I began to buck almost uncontrollably and James slid further down my shaft. Only a few inches were still visible and within moments even that slipped inside of him. His gigantic pecs slapped my chest as James rode my pole in a frenzy. I came just as he orgasmed.

I flipped him on to his back, my erection remaining rock hard. His oversized pecs stayed firm and jiggled only a little. Another climax hit me and I let out a roar as another shudder shook my body. James came again onto his eight-pack abs, his precum slicking his torso and glinting in the firm light.

James spun 180 degrees with my hammer still inside of him and stuck his ass in the air. I rammed him from behind. His pecs rested on the bed. He screamed my name when he came a third time.

We fucked deep into the night and finally fell asleep, exhausted, in each others arms.


Part 8

Sleepily, I unhooked myself from James’s sleeping body and walked to the bathroom. My cock slapped lightly against my thigh. I snapped awake when I felt my hair brush the top of the doorframe as I walked underneath it.

“What the hell…?” I started, then I did a double-take.

James ducked his head under the doorframe behind me, his bodybuilder-like frame filling the doorway. I had to look up to see his large beautiful eyes. Massive pecs swelled from his chest, casting dark shadows on his abs.

“Goodmorning, Sunshine,” he said.

I got a raging hard-on. Even in my stupor, I was shocked to see four more inches of cock than I had last night. James licked his lips.

We measured ourselves that morning after we fucked. I stood at an impressive 6’8” with a 11” dick hanging from my crotch. It was 19 inches when fully erect. James was a half an inch shy of 7’. We couldn’t even guess how big his pecs were, but they were much larger than Charlie’s were last night.

“James, what happened?” I asked, fearing that my growth had begun to take off like Jake’s had.

“Haven’t you figured it out yet?” he answered with a sweet voice, “I made a copy of both the stoner and regular soundfiles and put them on a CD. I played it last night in my brother’s CD player. See?” He pressed play.

A familiar chill wracked my body, and I could see James squirm through my squinting eyes. When it passed, I stood even closer to the ceiling. My dick crept down closer to my leg.

“James, my god, I don’t want to get bigger,” I moaned.

“Just once more,” he said breathily, and pressed play again. Within seconds I was hit with another cool wave.

When it was all done, I stood at an even 7’2” and James at a massive 7’5”. His taut muscled body rippled with power as he flexed. Softball sized biceps as big as my own swelled from his arm. Massive pecs arced off his chest, capped with 6 inch nipples 5 inches around. His nipples were bigger than some guys’ dicks! 30” thighs caressed a hot and amazing ass that just begged to be fucked. I answered the call with my raging 22” erection.

We fucked with our titan bodies throughout the day and the next.



I managed to sneak the special anthem CD out of the soundroom on Monday, but not until after the anthem played again. Many of the stoners experienced another noticable growth spurt, and continued growing for sometime after. Luckily, the growth seemed to cease after about a week. Most of the stoners started to reduce in size now that they didn’t have that constant flow of hormones coursing through their systems. Of course, not one of them shrunk in height. Our high school had a kickass volleyball team for years.

James and I continued dating. We continued to growth slowly over the course of three weeks as the last effects of the soundfile coursed through our system. I was 7’4”, 315lbs of solid muscle sporting a 17” cock, flaccid, and a 26” long 12” around erection. Not even James could take it all in, though he tried with all his considerable might.

Thankfully, James only grew another inch taller to rest at 7’6”. After a few months his frame began to tighten, much like the other stoners as he took on a more lanky look. He still a cut physique, but his muscles no longer bulged as if from a monster workout pump. What did bulge obscenely were his pecs. He easily filled a XXXXXL muscle tee. In class, he let his pecs rest on his desk, their mass filling the tabletop, barely giving him any space to write. He absolutely loved the challenge.

Jake came back from Houston standing at a towering 7’8”. The doctors couldn’t find any environmental factors or anomalies, and so chalked it up to overactive hormonal glands, probably genetic as his brother seemed to be suffering from the same effects. He tells me his dick is 24” long, which is perfect for pec fucking his new boyfriend Charlie and his moster pecs. He promised me this was the last harebrained scheme he was going to attempt. I just shook my head and smiled.
