Sonic growth

Sonic Growth

by Guhbone

"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 hairbrained 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 shinanigans. 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 chicks. I tried it out on my sister, and it works. I've got a plan..."

I knew it was another of Jake's hairbrained 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 athem with one with the national athem 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 babes grow, and snag them with our own growing dynamite bods. Nothing could go wrong.

***

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 girls 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 B-cups or bigger and tight asses. The tall blond had to be at least a D. My dick stirred at the thought.

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

Janna was a friend of mine from elementary school, but we grew apart once high school came. She wasn't very tall, only 5'2", but she was slim and cute and had a nice heart-shaped ass. 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. Janna's body was really taking to Jake's treatment. She had grown a couple of inches taller, her hips had widened and her ass filled out her jeans nicely. Her tits, well, I had to force myself to stop staring at her tits. They had grown from barely an A-cup to overflowing a C. I could see a bubble of titflesh bulge over the tops of her bra.

"Hi Trev!" she said in her sweet voice, her large green eyes twinkling.

"Hi, Janna," 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," she 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 Janna, though.

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

Steadying myself with a deep breath, I blurted, "Jannadoyouwanttogotothedancewithme?"

"Haha, what?" Janna said with a smirk.

That didn't come out right. I took another breath, "Janna, do you want to go to the dance with me?" My body tensed with anticipation.

"I'd love to, Trev," came her 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!" she said as she bounded away with her friends. She turned her head to look back at me still standing at my locker. She smiled as I waved. Her girlfriends giggled.

A loud bang snapped me out of my reverie.

"What the FUCK do you think you're doing talkin' to my girl?"

Fuck, it was Rick.

"She's not your girl 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 her, you little squirt," said Rick menacingly, "She'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.

***

Janna and I went on several dates throughout October and we were having a blast. She 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.

Her body continued to undergo changes. She was standing at 5'6", her straight dark hair had growth to the middle of her back, and her muscles were lean and defined. She confided in me a week before the Fall Dance that she was now wearing a 32DD now.

"I don't really know what's going on," she said, "It's like everybody is going through a growth spurt at the same time! Did you know that Karli is an F-cup 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 complimented cut pecs and solid biceps. I was 175lbs.

Jake was 6'3" and 195lbs. He was almost as big as Rick, now. He told 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 Janna to the dance, and was incredibly angry when he found out I was taking her. 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 Janna 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 Janna 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. Janna backed off.

"What is it, Trevor?" she 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," Janna replied soothingly, "Tonight's it's about you and me. This is the first time we have been along together." I caught the hint of anticipation on the edge of her voice. "I think you should be thinking about me." She bit her lowerlip and looked up at me with her beautiful eyes. We kissed passionately. Janna's hand rubbed my cock under my pants. Her kiss increased in intensity as she felt it's length stiffen and swell towards my knee.

"Look, Trevor," said Janna as she leaned back and undid her shirt, "I'm outgrowing my bra again."

I was looking. Both the underside and topside of her bra was overflowing with titflesh. I stared hard as she reached around and undid the clasps. Her tits sprang free and rested heavily against her slim ribcage. She dropped the 32DD bra to the ground.

I grabbed her jugs as she pushed me down onto the couch and kissed me. With one hand she undid my pants.

"I'm not the only one who's been growing, I see," she said breathily.

She worked my member free and slid down my body, her fat tits sliding along my torso. Her delicate hand could barely encircle my girth. "Holy fuck, you're huge."

She lift her head 11 inches up and wrapped her 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, Janna continued to suck me off.

Just as I was approaching a climax she stopped.

"No," I cried weakly.

"Shhhh," she said and climbed off the couch.

She slipped off her shirt, exposing her tits to the soft flickering light of the TV screen. She stared into my eyes as she ran her hands along the side of her body to her jeans, and ever so slowly popped the button off. With deliberate motions, she inched her tight jeans to the floor and gently stepped out of them, long smooth legs glinting in the light. She wasn't wearing any panties.

"You like?" she asked in a sexy voice.

"I like."

She smiled as she straddled me, her large naked boobs bouncing in the air. Her nipples puckered.

I grabbed her right breast with one hand and put her fat nipple in my mouth. Janna gasped, "Oh, Trevor..."

With my left hand I traced her abs down to her waiting pussy lips. Carefully spreading her plump lips apart, I placed my middle finger on her clit. Janna shuddered in pleasure. I worked my fingers inside her cunt while I sucked on her breast, flicking her big nipple with my tongue. I could her arm slide next to mine and grasp my cock. She directed my cockhead to her pussy lips. I withdrew my fingers from her hole and began working her clit.

She pushed herself down onto my shaft, her moist sex enveloping me. I could feel the walls of her pussy stretch against the girth of my penis. She paused to let herself adjust to my size. I switched to her other breast and began sucking.

After a moment she pushed herself farther down my shaft, taking in 9 inches. "Oh god Trevor you fill me up..." Another push and her lips reach my base, my entire 11 inch cock inside of her, her soft ass resting on my thighs. "Yes, oh god yes..." Tears squeezed out of her closed eyes.

She lifted her hips high, almost to the point where my cockhead would pop out of her, and pushed herself down. Hard. She squeaked.

Again and again she rode my cock, it's entire length glistening in her juices. Her tits bounded up and down on her body, slapping against her chest. My hands found her wide hips and squeezed.

We came together, me with a mighty roar and she with an ear-splitting scream. She lied panting on my chest. I could feel her soft tits pressed up against me.

***

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

"Trevor, I got bigger," she said simply. I blinked.

She took me to an isolated nook in the corner of the hallway. "I couldn't fit into any of my bras this morning," she said.

She opened her coat to show me. I could clearly make out both fat nipples pressing against the fabric of her shirt. Her tits were surprisingly perky given their size.

"I'm at least an E, maybe an EE," she whispered.

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

She went on her 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.

***

Janna and I had sex every night my parents were gone. She had gotten bigger, as it turned out, and continued to get bigger as the days wore on. By Thursday she was officially a 32EE, and even that was beginning to show strain. She was standing at 5'7". I wasn't sure if she noticed, but I, too, grew bigger. I was now 6'1", 190lbs, with an 11 1/2" erection. I think she 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 through 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 sister Melissa. I found her sitting with her grade 10 friends in the back corner of the lunchroom. They all smiled at me when I approaced and a more than a few showed off their generous cleavage. Not one of them had less than a D-cup.

Tearing my eyes away from one girl's double-Es, I turned to Jake's sister, "Melissa, can I talk with you for a minute?"

"Sure thing, Trev," she answered as she stood up.

I took a step back in surprise. She was two inches taller than me. Her massive tits strained at her tight shirt. Those suckers had to be at least G's as they hung nearly to her navel. Recovering quickly I lead her aside.

"What's happened to Jake?" I inquired.

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

"Thanks, Mel," 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 GIRL!" 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 Melissa.

I sat up, bleeding from my lip, to see Rick on the ground, pinned by the gaggle of grade 10 girls. 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.

***

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.

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

"Yeah, get a good look now, because it'll be a while until you see them again," she 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 Janna tonight.

"Stupid Rick..." I grumbled.

"I'm so sorry, Trevor," soothed Janna, "I told Tiffany we slept together, who told MacKensie who told Laura who told Tom who told Rick. I'm sorry."

"It's not not your fault, Janna," I replied.

"Janna, it's getting late," I heard my mom from downstairs.

"Thank you Mrs. Swick!" Janna said back. She gave me a quick peck on the cheek, "I'll see you in seven days." My one good eye followed her ass as she 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 girls 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 Janna's number.

"Trevor?" I heard her answer.

"Hi Janna," I melted at the sound of her voice.

"Oh Trevor, thank god it's you," said Janna, "Something's been going on this week and everybody's starting to notice."

I gulped.

"All the girls are getting really...big..." continued Janna. Silence. "Even me," she finished.

I gulped a second time.

"Trevor? Are you listening? I'm a 34H now," she whimpered into the phone, "My tits are so huge and heavy. My mom is freaking out over my bra expenses. And clothes. I'm 5'10". I grew 3 inches in a week! It's crazy!"

I gulped a third time.

"Trevor...?"

"Janna, I've got something to tell you..."

I filled her in on the whole hairbrained tale.

"That's why Jake is in the hospital? That's why you've got...you've gotten bigger, too?" she asked.

"Yep," I said simply.

"And that's why all the girls are getting so..such huge tits? Karli's a K! Melissa is like 6'5"!"

"Yep," I said sheepishly. It sounded really jeuvenile to hear it from her.

"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 guys growing?"

"Jake somehow had it tuned to females," I answered.

There was a long silence.

"Have you stopped listening to the sounds?" she asked quietly.

"I have," I replied.

"Oh."

'Oh?' Did she sound disappointed? She might be. Rick used to be her boyfriend.

"Janna?"

"Yes, Trevor?"

"Did you want me to get...bigger?"

"I would never force you to," was her reply, "but..."

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

I heard Janna giggle, "Goodnight Trevor."

"Goodnight Janna."

I popped in the CD.

***

"So that's what a 34H looks like," I said to Janna as she walked towards our lockers.

"34J," she quipped, "I grew some more overnight."

"You skipped right over 'I'?"

"There is no such thing as an I-cup, it looks too much like a 1," said Janna, smiling.

"Oh." How was I supposed to know that? Still, she looked fabulous. Her twin orbs jutted proudly from her chest and shook mesmerizingly with every step she took. A slim waist flared out into the most curvaceous hips that banked an ass that just begged to be squeezed. Her long glossy dark hair was drawn back in a ponytail, highlighting her high cheekbones and beautiful large green eyes. Her delicate thin lips pursed into mock amusement.

"Don't worry, I just found that out, too," she said. She threw her arms around me and kissed me with those soft lips. I felt her huge jugs press into me.

"I missed you," I murmured.

"I missed you, too," she whispered.

"I gotta run," I said, reluctantly breaking away from her 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 girls were hot, busty 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 tits I saw were as big as cantaloupes and the biggest rivalled basketballs. Even though Janna was filling a 34J bra, she wasn't the biggest. Several girls had bigger breasts, especially those who had big cans to begin with.

I walked into the soundroom and stopped.

"Trevor, we've got Harry doing the announcement this week," said Mrs. Albright as she 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 girls in the class give a little shudder. I paused mid-sit and glanced at Karli next to me, her K-cups resting on her desk. I could've sworn that I saw her huge orbs swell just then. I sat down completely.

I wasn't dreaming. I took stealthy glances in Karli's direction every chance I got, and by the end of class I could tell that she had begun to overflow her cups. A large ridge had formed where her bra met her boob and was clearly outlined in her tight sweater. Her jeans looked tigher, too. All of the girls in class fidgeted absentmindedly with their clothes the entire class.

By lunchtime, a third of the girls at school had gone home 'sick.' I wasn't surprised. Half of them were bursting out of their bras. In fact, a few girls' bras did snap, the girls' faces turning red as they bolted from the classroom. Many of those girls remaining had just abandonned their bras altogether, Janna among them. Nipples jutted out proudly no matter where you looked.

"My bra was just getting too tight to be comfortable," she said with a mouthful of fries, "I had to take it off."

"I'm not complaining," I said. Unsupported by a bra, Janna's big tits hung lower on her chest but still sloped nearly a foot away from her. They practically rested on her lap. She leaned over to get more fries.

"Oof!" she said. She grabbed her left breast in both hands through her shirt and hefted it's considerable weight onto the table. She did the same with her right breast, titflesh overflowing her hands. "That's better," she said and grabbed more fries.

A lot of girls were doing the same. Giant tits rested on the tabletops all over the lunchroom, girls 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 Janna, "It must be this 'growth spurt' I'm going through." She winked at me and had another bite of her double cheeseburger.

"Well, this 'growth spurt' will have to end soon," I said, as I saw a girl stand up next to me. She was over six feet tall.

Janna sighed, "I know." She leaned forward across the table and looked me in the eyes. Her tits flattened out across the tabletop. "Want to know what a 34K tit feels like?" she whispered in my ear. I got rock hard in an instant.

Janna finished her burger and stood up, her jugs wobbling unrestrained under her shirt. Thumbsized nipples tented just above where her bellybutton would be. I followed her 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 Janna's round ass and the sides of her tits, which I could see on either side of her. They bounced in time with her step.

She lead me to small girls' washroom on the fourth floor and locked the door behind her. She had a devilish look in her large eyes.

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

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

Deftly she undid her pants and pulled them off. Long legs that wouldn't be out of place on an olympic gymnast managed to wrest my eyes from her tits. Legs of a female olympic gymnast, anyway. They were still quite womanly. I watched her calves flex as she walked towards me, big boobs wobbling in the air.

She ran her delicate 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 her enjoyment. She cooed and ran her soft fingers under my pecs. She traced her fingers down between my abs and graped my cock, which was still sticking out from my waistband. She smiled with lust.

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

"I think you've gotten bigger, Trevor," she whispered in my ear.

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

My hands found her ample hips and squeezed. I lifted her easily and poised her moist pussy at the head of my foot long cock. She wrapped her long smooth legs around my torso. I thrusted her down onto my cock.

"Oh god Trevor oh god!"

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

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

We went back to class that afternoon sated and happy.

***

I completely misjudged what harm two more days could do.

I was huge. I shouldn't have let Janna 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. Janna 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 girls missed school that day. Another shudder went through the present female student population after the anthem and another growth spurt followed. I had a hard time concentrating.

I didn't see Janna at her locker this morning. I hoped she was okay. Today was the night of the Dance.

It turns out she was here today. She found me standing in line for food in the lunchroom. She snuck in behind me, her huge tits pressing into my back. She whispered into my ear, "I'm wearing my 36L bra."

36L?? I turned around. She was tall.

"Oh, and I'm 6'1" now," she smiled coyly, "At least, I was before this morning's anthem. I see you've grown, too." She traced her hand along my arm.

We snuck off again to the fourth floor bathroom to have sex. Janna 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 sister lent me her apartment for the weekend. We can hang out there after the dance," Janna said with a wink as we walked into the school that night for the dance, hand in hand.

She was positively radiant in her tight backless sundress, every curve of her clearly outlined. I could see her back muscles flex carrying the weight of her L-cups. She and I nearly stood eye to eye with her wearing her 2 inch heels. I think she got a kick out of that.

I handed our tickets to the cute little grade 10 girl manning the ticket booth. She had to reach around her H-cup tits to put them in the envelope, six inches of soft cleavage rippling with the effort. Janna smacked me lightly when she caught me staring. I smiled sheepishly while she just grinned and rolled her eyes. She squeezed her arms together on either side of her boobs, forcing nine inches of her 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," Janna 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 girls in the gym. Janna squeezed my hand, eyes wide and lips curling in pleasure. The fabric on her dress grew taught as the growth spurt hit her.

Ten, then eleven inches of cleavage became visible as Janna's tits grew larger right in front of my eyes. Her muscles tensed as they became larger and more defined, and her ass widened and filled out a few more inches. She actually laughed when she looked me straight in the eye and realized she didn't have to look up to do it.

We danced the night away.

Janna wasted no time pushing me onto her sister's vacant bed much later that evening. My discarded clothes left a trail from the apartment's door to the bedroom. Janna, standing near the CD player, turned her back to me as she reached down and pulled her dress over her head, the fabric clinging and stretching over her massive boobs the entire way. A black thong was wedged between her tight ass cheeks and a 5 clasp bra dug into her toned back. Her tits were spilling out of her now too-tight bra and they sprang free with a heavy bounce when she unhooked the final clasp.

Janna's tits hung from her chest to her navel and capped with fat pink nipples that puckered in the air. They swayed mesmerizingly as she walked to the edge of the bed. My face was pressed between her soft cleavage.

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

Leaning back, she took both hands and guided my rock-hard cock into her waiting pussy and pushed down. I could feel her tight lips stretch over the head of my cock as seven inches slipped inside of her. Janna's nipple swelled in my mouth.

I began to buck almost uncontrollably and Janna slid further down my shaft. Only a few inches were still visible and within moments even that slipped inside of her. Her gigantic tits slapped my chest as Janna rode my pole in a frenzy. I came just as she orgasmed.

I flipped her on to her back, my erection remaining rock hard. Her tits spread across the bed and jiggled wildly with my thrusts. Another climax hit me and I let out a roar as another shudder shook my body. Janna came again onto my cock, her juices slicking my cock and glinting in the soft light.

Janna spun 180 degrees with my hammer still inside of her and stuck her ass in the air. I rammed her from behind. Her tits rested on the bed and spread out to her sides, their fat encircling her arms. She screamed my name when she came a third time.

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

Sleepily, I unhooked myself from Janna'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.

Janna ducked her head under the doorframe behind me, her bodybuilder-like frame filling the doorway. I had to look up to see her large beautiful eyes. Massive tits swelled from her chest, coming to rest just above her hips.

"Goodmorning, Sunshine," she 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. Janna licked her 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. Janna was a half an inch shy of 7'. We couldn't even guess how big her tits were, but they were much larger than Karli's was last night.

"Janna, what happened?" I asked, fearing that my growth had begun to take off like Jake's had.

"Haven't you figured it out yet?" she answered with a sweet voice, "I made a copy of both the female and male soundfiles and put them on a CD. I played it last night in my sister's CD player. See?" She pressed play.

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

"Janna, my god, I don't want to get bigger," I moaned.

"Just once more," she 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 Janna at a massive 7'5". Her taut muscled body rippled with power as she flexed. Softball sized biceps as big as my own swelled from her arm. Massive tits arced off her chest, reaching her pubic area, capped with 6 inch nipples 5 inches around. Her nipples were bigger than some guys' dicks! 30" thighs caressed a swollen and dripping pussy 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.

Epilogue:

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 girls experienced another noticable growth spurt, and continued growing for sometime after. Luckily, the growth seemed to cease after about a week. Most of the girls 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 woman's volleyball team for years.

Janna 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 Janna could take it all in, though she tried with all her considerable might.

Thankfully, Janna only grew another inch taller to rest at 7'6". After a few months her frame began to soften, much like the other girls as she took on a more feminin look. She still a cut physique, but her muslced no longer bulged obscenely. What did bulge obscenely were her breasts. She easily filled a 40Q bra. In class, she let her tits rest on her desk, their mass filling the tabletop, barely giving her any space to write. She absolutely loved the challenge.

Jake came back from Houston standing at a towering 7'8". The doctors couldn't find any enviromental factors or anomolies, and so chalked it up to overactive hormonal glands, probably genetic as his sister seemed to be suffering from the same effects. He tells me his dick is 24" long, which is perfect for titty fucking his new girlfriend Karli and her 36Ps. He promised me this was the last hairbrained scheme he was going to attempt. I just shook my head and smiled.
