After-Effects

-------------------------------------

I awoke to the suns early rays peeking through the slats of my blinds of the window of my basement suite.  After rubbing the sleep from my eyes I gingerly slipped out of the bed so as not to disturb my girlfriend Shannon, her petite form gently outlined under the covers.  I tiptoed to the washroom and took a leak, fantasizing about last night's sexual escapades.  She was like a wild tigress last night!  As I finished up I felt myself grow hard and watched as my dick swelled to its full six inch rigid state.  I let it subside and yawned as I crawled back into bed.

I awoke again to find Shannon caressing my cock, coaxing it into an erection.  I murmurred in pleasure as her small hands delicately stroked my dick to life.  Within moments I was fully erect.

"Holy crap," Shannon said suddenly, snapping me out of my pleasant reverie.

I opened my eyes to seeing Shannon kneeling next to me, mouth agape, staring at my erection.  And then I noticed my erection.

"Holy crap!" I exclaimed.

My dick was significantly longer than it should have been!  Instead of the regular six inch boner I had since I was a teen, I was sporting an eight incher.  In shock I sat up and felt it myself.  It was real.  It even felt a little thicker than normal.

"What happened, Luke?" Shannon asked.

"I have no idea," I replied, "I had gotten up earlier to take a leak and it was fine then.  I don't know what's happening."

We sat in stunned silence for a moment, starring at each other blankly.

"Well, I guess it's not all bad," Shannon said with a smirk.  She pushed me onto my back and straddled my hips.  With one hand she guided the tip of my cock to her pussy and stroked her clit, making her wet.  Within moments her juices were coating my cock.  Instinctively, I reached up and tweaked her small perky nipples.  With a gasp, she thrust herself down on my cock, my eight inch pole disappearing into her snatch.  Her eyes shot wide.

"Holy crap!" she cried again, "You're so big!"

Again she slammed down on my cock, riding it with a frenzy I never knew she had in her.  I thrust back in rhythm, squeezing her hips in my hands.  With a grunt and a scream, we both came.  Shannon collapsed, exhausted, onto my chest.  I exhaled and ran my fingers through my hair.  That was intense.

After a few minutes Shannon rolled over and my limp dick popped out.  I looked at it.  It looked about six inches long, flaccid, and filled my hand nicely.  I wanted to measure so I got up and dug my ruler out of my desk.  Holding it up I confirmed that my soft dick was roughly six inches long.  Before, I was only about 4 to 4 and a half inches long.

"Somehow I grew about an inch and a half between this morning and just now," I said in wonder.

"How long are you hard?" Shannon asked.

"I doubt I could get it up again so soon."

"I could try..."

Demurely, Shannon crawled to the edge of the bed with a sultry look in her eyes.  What has gotten into her?  She was never this forceful before.  She swung her legs over and sat at the edge of the bed.  Carefully she drew me closer and gently slipped my cock into her mouth.  My eyes rolled back into my head.  Her expert tongue work quickly got my cock hard again and she popped her mouth off the end.  I looked down to see my cock again jutting out majestically from my groin.

Shannon took the ruler from me and placed it at the base of my erection.

"You're just under eight inches long Luke," she said as she got up and headed to the washroom.

"Wait! That's it?  You're not going to finish?" I cried.

"Luke, c'mon!" she tossed back, rolling her eyes, "We just had sex.  I think you're good for now."  She strolled into the washroom and closed the door.  I sighed.

My erection subsided quickly as I gathered up my clothes and some new underwear and tidied up the bed some.  I went to slip on my underwear when I got my second shock of the day.

"Holy crap!" I exclaimed, again.

"What is it baby?" Shannon yelled out from the washroom.

"It happened again!"

Lying in my hands was my flaccid cock, flopped over the edge of my palm, some four inches or so of it dangling in the air.  Shannon was just exiting the washroom, her svelte form outlined in the light of the doorway, as I again put my ruler next to my cock.

It was just under eight inches.  Just like last time we measured.  But this time it was flaccid.

Shannon crouched in front of me and inspected my cock dangling between my legs, a look of awe washing over her face.  She craddled it - it looked so big in her hands.  And indeed it was.  She turned her head up towards me with such an expression of need on her face as she played with my cock that I couldn't help but harden again.  Thicker and longer than before it grew, some ten and a half inches long and probably seven around.  She never broke eye contact as she slipped the monster into her mouth and sucked.  Stroking me off and sucking, she brought me to a climax and I came hard into her mouth.  Exhausted, I collapsed against my desk.

"Oh god, I feel so...oh god!"  Shannon fell back onto the bed and began to finger herself furiously.  I watched, mesmerized, leaning against the desk as she worked herself to a climax.  Her left hand run up her taut waist to her small tits and tweaked her nipple.  My jaw dropped.  Her tits were swelling!  With a cry she came and sprawled herself out on the bed.  Her chest heaved.

"Shannon...your tits," I managed to splurt out.

"What...?" she said as she sat up.  Her tits jiggled in the air.  She cupped her tits with her hands. They were small handfuls now, whereas before they were barely more than nipples.  My overworked dick stirred, only eight inches long again dangling flaccid from my groin.

I walked over and sat on the bed and began to caress Shannon's tits.  They felt wonderful.  Probably B-cups.  I tweaked a nipple, which I knew she loved.  She gasped.  We explored them together on the bed.  I could feel myself grow aroused, and my erection again began to snake out and harden.

"I've always dreamed of having tits," she confided in me.  The realization of what was happening had dawned on us.  When I get hard, but fail to release, my dick maintains its erect length as it softens.  When she sucks me off, her tits grow.  And I knew what she wanted right then.

Again she pushed me onto my back and knelt between my legs.  My ten and a half inch erection sprung between us.  With a savage glee she attacked it, sucking and stroking with a wild abandon.  It took my by surprise and I came within moments, spewing great gobs of cum into her mouth.

She fell back, captured in the throes of passion like before, madly fingering herself.  I sat up to see her tits begin their expansion.  Like a water balloon they swelled on her chest as she rapidly stroked her pussy.  She moaned in frustration, unable to release.  Suddenly, she grabbed my still-erect cock and tugged.

"Fuck me!" she screamed.

I barely had time to react as she plunged my huge cock into her pussy.  She was so tight.  Instinctively I began to thrust, sinking deep into her.  Shannon cried out in pleasure and pain as her breast growth accelerated.  Her boobs swelled past C's and into D's in seconds, which looked huge on her small frame.  She came almost immediately after and sighed in pleasure.  I thrust a few times before pulling out.

But she wasn't done.

She flipped around and began another round of fellatio.  My eyes rolled back in my head as the wave of pleasure hit me.  Amazingly enough, I came again in short order.  Where did all this stamina come from?  I collapsed back onto the bed exhausted.

I must have passed out because when I opened my eyes again it was three in the afternoon.  Shannon was nowhere to be seen.  I got up off the bed, my cock and balls slapping against my thigh, and went to the washroom again.  It was odd feeling my dick swaying in the air like a fat pendulum.  I got to the washroom and inspected myself, and did a double-take.  My balls!  I reached down and cupped them.  They were much larger than they should be, like the size of pool balls or so.  How did that happen?  I played around a bit more only to start getting a semi-erection.  In a panic I tried to think of something else.  I dare not risk having another erection!  I was already huge!  

It wasn't working.  

Thinking about not having an erection just seemed to aggrevate the situation and before long a mighty ten and a half inch boner jutted majestically from my loins.  With only a tinge of regret I sat myself down on the bed and began to jackoff, knowing that unless I had a release I'd be stuck with a ten and a half inch flaccid cock.  It was an interesting experience.  My hand travelled up and down the length of my shaft in long strokes, building up tempo.  The pleasure built and I came.  Like a firehose.  It was a marvelous release, incredibly intense.  But something felt...weird.  I opened my eyes to see my hand gripping my small erect penis, maybe five and an quarter inches in length - literally half the size of my previous erection.  It deflated in my hands, shrinking to maybe three inches flaccid.

Shocked, I stood and looked at myself in the washroom mirror again.  It was an odd sight to see such a puny dick alongside such massive balls.  I waggled it a bit just to watch.  So, when I jacked off my dick shrinks to about half its current size.  What a strange thing.  But a five and less-than-half inch boner just won't do, especially after experiencing what a ten-inch-plus one felt like.  Trusting that my stamina was still there and whatever magic was causing all this was still working, I worked my dick into another erection.  It did take longer than before - understandable after the day I've had - but still it sprang to life.  My modest erection stood before me.  I just let it subside naturally.  Sure enough, after a few minutes my dick went flaccid and, to my relief, retained its nearly five and a quarter inch length.

This gave me an idea.  Time to experiment.

Just the thought of what I was going to do stirred my dick, and it didn't take much to get it erect again.  I grabbed my ruler to measure.  Just a bit longer than seven inches.  Respectable to be sure, but not what I had in mind.  I sat down and started reading a magazine, letting my new erection subside.  After a riveting read on volcanoism, I noticed that my dick sat limp between my legs, stretching roughly seven inches from my groin.  With a smile, I grabbed it and stroked it back to life, taking in the pleasure as it swelled in my hands.  Once hard, I measured.  Nine and a half inches.  Better, but still not enough.  I went back to reading.

After skimming through another few articles, I put down my magazine and grasped my now-nine-plus-inch limp cock and worked it up to an erection.  It was a little frightening to see this monster swell in my hand.  And it was so thick.  It stretched about a half inch past the end of my 12-inch ruler.  I grabbed some cord, wrapped it around the base of my cock, marked it, and measure the girth.  Just over seven inches.  I had a monster of a cock.

But I craved more.

About a half hour later I stood up and watched in awe as a flaccid footlong dick hung heavily from my groin.  I turned sideways and inspected myself in the mirror.  The great python curved over the swell of my ballsack and dangled next to my thighs, fat and heavy.  I shimmied my hips and watched as it flopped from side to side, banging into the cabinet with a whump.

With great anticipation I grabbed it with both hands, the soft shaft resting in my palms.  It was unbelievably large.  With a few deft strokes I could feel it stir in my hands.  I watched as my dick snaked outwards, hardening as I played with it, elongating with every soft stroke.  Soon I had a massive and massively thick erection jutting from my groin.

I measured with the string: 16 and 3/4 inches long by just over 8 inches around.  My balls were almost looking too small again.  Stroking its epic length felt incredible, and I almost came right then, but I resisted.  Seeing and feeling such a massive rod was something else!

But in the back of my mind I wondered....how big could I get?

With some willpower, I let my cock go.  I watched as it slowly deflated, mysteriously retaining its girth and length.  Before long, I had a near-seventeen inch dick resting on the bathroom counter in front of me.  I pulled back a bit and gasped as the entire length slid off the edge and slapped against my legs.  The weight was greater than I expected!  My dickhead dangled to my knees.  I reached down and grabbed the end and brought it upwards.  My hand couldn't even encircle it's girth and it was so long it curved in a giant U shape.  Letting it go again it dropped back down and slapped my knees.  I swung my hips a bit and watched as my dick swung pendulously back and forth.  I walked back into my room (causing my huge dick to flop around wildly) and grabbed some underwear and slipped it on.  I tried stuffing my oversized cock and balls inside resulting in a comical bulge about the size of a large cantaloupe.  I then tried wrapping my cock around my waist - my head nearly reached my ass-crack.  Wow.  I pulled my underwear off again quickly, finding the whole thing uncomfortable, if a bit amusing.

I didn't hear Shannon as she unlocked my door and came downstairs to my suite.  I did hear her gasp though as she saw me buck naked in the middle of my room with my underwear around my ankles and my giant dick dangling to my knees.

Giant braless tits were clearly outlined in her tight baby-T, her big nipples tenting the fabric.  Her tits were about the size of large cantaloupes themselves, but with a natural slope and curve and far more jiggle.  Since I passed out before I got to see her latest round of growth I had no idea she had swelled so huge.  I couldn't imagine what size they were.  F's? G's?  In any event, they were immense.

Naturally, my dick stirred at the thought.

"What happened, Luke?" said Shannon, overcoming her shock as she made her way towards me.  She ran a hand down my chest, over my abs and to the base of my hardening cock.  She couldn't hope to encircle it.

"I...I was experimenting," I stammered.  Her hand ran partway down my shaft and back up again.  My semi-erection was nearly horizontal by then.

"I see that," she murmured.  Her eyes had begun to glaze over with lust.  Briefly the thought of my girlfriend's overcharged sexual appettite skittered across my mind, until it was chased away my another stroke of my cock.  Shannon was now standing in front of me next to my full erection.  It jut past her hip and beyond some twenty two inches from my groin.

With a look of seduction she stepped back and slowly pulled her t-shirt over her head.  Giant round tits flopped out and wobbled in the air.  With purposeful slowness, she knelt before me and slipped both of her tiny hands around my dick and brought the head of my cock to her mouth.  I gasped as she valiantly tried to fit the monster inside her, getting about 4 inches in.  Her tongue and hands then began to rub and stroke with increasing fervor and a wave of indescribable pleasure took me.  I came mightily.  Shannon's cheeks puffed out as the surge of cum hit her.  She greedily swallowed as much as she could, great gobs dribbling down her chin.  When the last spasm shook me I collapsed backwards onto the bed.  Shannon moaned.  My balls swelled.

I craned my head up to watch as Shannon stripped off her jeans and pleasured herself like a madwoman.  With each breath her tits swelled larger and larger, from soccerballs to basketballs and beyond.  With a cry and a final surge she came and fell back onto the floor beyond my sightline.

With a heave I sat up to look at my girlfriend.  Her tits were...the word "massive" just didn't do them justice.  Her tits sat heavy and full on her chest, over her torso to her hips.  They would dwarf a prize watermelon in size.  She smiled a dazed smile with heavy-lidded eyes, coming down as she was from her orgasmic high.  She looked me in the eyes and squished her gigantic tits together, forming a mountain of tantalizing cleavage from her chin to her navel.  My god those tits were huge.

With some effort, Shannon sat up crosslegged, causing her huge tits to rest heavily in her lap.  They completely filled the gap between her knees and swelled out past her crossed ankles. With a heavy grunt she then swung her knees under her and pushed herself up to standing.  She had to take a moment to steady herself as the weight of her chest threw her slightly off balance.  Her tits wobbled in the air, slapping her hips.

Beyond all comprehension, I could feel an erection stirring.  How that could be just after what I experienced was flabbergasting.  With another devious look in her eye, Shannon pushed me back onto the bed and began fondling my oversized cock and balls.  Soon my 22 inch erection wavered straight up into the air as she knelt, straddling my legs.

"I wanna try something," she said.

She scoped up her giant boobs and squished them around my shaft and began to rub my dick with her tits. I was rock hard and close to coming. Suddenly she stood up, grabbed my cock, crotched and angled it into her snatch.  Her giant tits wobbled next to her hips. I blew my load.

Shannon exploded in size.

My oversized cock sunk deeper and deeper into her snatch as her entire body expanded at an incredible rate.  I felt her hips rapidly widen in my hands and her legs elongate alongside my body.  Her head moved up and away from me as her torso stretched.  Her already titantic boobs swelled as she did, maintaining their proportion to her size, and quickly their soft weight spread over me. Soon, my suddenly-gigantic girlfriend had my hard cock pressed to the hilt, all 22 inches buried inside her.  With a sigh of pleasure she collasped on to me, her massive breasts smoothering me in soft flesh and pinning me beneath her huge body.

Slowly, as her orgasm subsided, Shannon pulled herself up and off of me, only to bump her head on my ceiling.  Now it was my mouth that was agape.

She had to be nearly 9 feet tall, but in perfect perportion to her original pixieish build. Her teardrop breasts were beyond gigantic as they hung to her hips, which were themselves nearly five feet from the floor.  A little woozy, she recovered her balance and leaned forward a bit so that she could stand under my ceiling.

"That was unexpected," she said with a smirk.

"I'll say," I sputtered.

More fascinated than alarmed, we explored the changes in her body.  Somehow, she grew large enough to accomodate the entire length of my cock.  She was so tall now she simply towered over me and everything else in my suite.  Even when seated (with her breasts resting in her lap) her head nearly came to my chin.  Her pussy was enormous - my entire hand slipped inside of it easily - stretched and worked as it was after taking in my massive python and her body quadrupling in size.

Then again, my cock was dangling past my knees, so...

Shannon caught me looking at my cock with a sheepish grin, and with a silent crooked smile of her own she got on to her hands and knees, huge boobs puddling around her wrists,  and guided my huge cock into her huge mouth.  With very little coaxing she managed to get me hard again.   Over half of my 22 inch cock disappeared down her throat.  After all that had happened today and the state that my mind was in and the state that our bodies were in, the experience was too much and I blew my load in a manner of minutes.

Shannon's humongous boobs on her humongous frame swelled rapidly in reaction to the recent injection of hot cum from my oversized organ.  Shannon's eyes rolled back in rapturous pleasure as tits already the size of beanbag chairs doubled in mass. When it was finally over, Shannon discovered that she was pinned to the ground by the immensity of her tits.  And were they ever immense.  My big dick flopped against my legs and my enlarged balls as I walked around Shannon inspecting her predicament.  Her giant body was resting on her tits, arms draped to their sides, her chin nestled in expansive cleavage and on the other end her hips propped up in the air. It was like she was laying facedown on two giant wobbly mattresses.

Finally I said, "What do we do now?"

Thinking it over, Shannon replied (in a remarkably calm voice, given the situation), "Well, it seems that when we engage in sexual activities, some growth of somesort occurs.  Except for when you jackoff - that caused you to shrink down again.  Maybe if we experimented some more....?"  She trailed off.

'What haven't we tried yet?' I thought to myself.  As if she read my mind, she said aloud, "You have yet to eat me out."

'Not a bad idea', I thought as she smirked.  I walked behind her, stepping over one giant leg as she spread her thighs apart.  Her giant pussy was moist and red, puffed up from today's exploits.  Without hesitation, I plunged my face into that huge snatch and went to town.  Shannon bucked in pleasure as I expertly tweaked her pussy as only I knew how.  With her overworked pussy and the sheer area I had to administer, it took a while longer than it usually did for her to orgasm, but orgasm she did, creaming heavily into my face.  She trembled and bucked in pleasure, and to our delight, with each buck she shrunk a little in size!  As the orgasm wore down, the trembles decreased in intensity, and soon, lying on the floor beneath me was a small Shannon, probably no more than four and a half feet tall.  With her elfin build, she looked especially tiny. Her breasts had shrunk as well, but only proportionately.  They were still so massive that they spread out from her chest like giant pillows, their weight too much for her or I to move with any real effectiveness.

"Well...," she huffed, still coming down from that latest high, "...that was something, at least.  We just need to try something else now.  These tits are just too big to move."  I sat back and my giant 22-inch erection sprung up between my legs.  Eating out my girlfriend always turned me on.  But I didn't have the energy left to jack off, so I just let it subside.

"God, I'm so tiny," I heard Shannon say.

As expected, within a few minutes I had a soft 22 inch python resting on the floor between my legs.  My cock was so fat now that it had to be at least a foot around.

Suddenly, Shannon said "You could fuck me up the ass."  I was a little shocked but then thought, 'That is definitely something we haven't tried!'  But, being that I was seated behind her out of her line of sight, I don't think she realized my had cock grow some more.  I got up - my fat dick dangling to mid-shin - and walked around my sprite-like girlfriend.  Her jaw dropped.

"Yeah okay!  Not with that fucking elephant cock you aren't!" she exclaimed. I chuckled.  Knowing what I had to do (and hoping I still had the stamina to do it) I sat down and started working at my dick.  It took some effort and a lot of staring at my girlfriend's tits to get my tired cock to swell into an erection, but swell it did.  It was frighteningly large - 30 inches long and so big around I needed two hands to encircle it.  After a moment of awe, I began jacking off in earnest.  My hands glided along the shaft in a wild frenzy, attempting to stimulate a dick so big.  A wave of pleasure flooded my brain as an incredible orgasm wracked my body.  Great gobs of cum shot forth from my shaft as I rode the one of the greatest orgasms of my life.  In the end, as expected, my dick had softened to half its previous size.  The beast still dangled some 11 inches from my groin, but it was way more manageable now.

Even though I only had that ludicrously oversized cock for a few minutes, I already kind of missed it.  I can't believe I was thinking it, but this 11-inch-dangler felt kind of small.  I knew that erect it'd be about 15 inches - far larger than any normal sized cock - but still...

"Baby, stop admiring yourself and get hard again," Shannon snapped me out of my reverie, "I am getting tired of laying trapped on the floor."

"Right," I said and got up and walked around her yet again.  She propped up her ass in the air in anticipation.  Like whatever magic was at work before, when she shrunk she shrunk to half the size. When Shannon was gigantic, she was probably over 9 feet tall.  Now, she was less than 5 feet.  She wasn't much over 5 feet to begin with, but losing half a foot in height and a proportionate amount in size was significant.  I could tell as I cupped her ass that it was smaller than it used to be.  Seeing her prone before me, ass up, resting on massive tits got me worked up in no time and soon I was guiding my 15 inch cock to her ass and slowly coaxing my way in.  My cock was still pretty girthy and it was slow going and a little painful for her.  My gigantic cock looked even more so next to her tiny ass. With only about 3 inches in she pleaded, "Is that enough?  You are just too huge."  That pleading voice just did it for me and with a couple of short thrusts and a few expert strokes I came.

"Oh god my whole body is tingling!" she cried.  I felt her ass swell in my hand.  Shocked, I fell back, popping out of her ass.  "Oh god!" she cried again.  Her tits weren't shrinking.  She was growing.  But not in size - she was plumping up!  I watched as her belly, ass and thighs expanded with soft chub.  She was moaning in pleasure.  Whatever was the case, no matter what the change, it always seemed pleasurable.  Within moments, the growth subsided.

"I'm fat," Shannon stated succinctly.

She was definitely plump.  Not counting her breasts, and given her original weight of about 115lbs and estimating that at her shrunken stature she would probably only about 90lbs to 95lbs, I guessed that Shannon had doubled in weight, probably close to 200lbs now.  Her thighs and hips had swelled the most, but her belly wasn't far behind.  Even her arms pudged out a bit.  This wasn't what we were expecting to happen... but I found it strangely arousing.  Oddly, I felt less weight hanging from my groin.  My dick size hadn't changed, but I noticed my balls had diminished some.  At least that was a welcome discovery.

Unfortunately, Shannon's tits didn't shrink at all.  In fact, they plumped up a little themselves, just as Shannon herself did.

Taking stock, we knew now how to make my dick grow and shrink, my balls swell or shrink, Shannon's tits grow and Shannon's height and size to grow or shrink, and, just now, how to make Shannon plump up.  There wasn't much left for us to figure out (if reason and logic were to be trusted, that is!) but then there wasn't much left on the grand scheme of things to try out, either.  We took some time to recharge, had something to eat, I got dressed and also draped a blanket over the naked Shannon, and thought about what else we could try, to see if we could do something to shrink those tits (and now also thin her up).

Then something occurred to me.

"Hey, when you fingered yourself after sucking me off, your tits seemed to grow extra big," I said, "Maybe if I fingered you it'd have the opposite effect?"

"Worth a shot!" she replied.

Once again I found myself kneeling between my girlfriend's legs, one hand on her plump ass and the other tweaking her tiny snatch.  Playing with her clit quickly brought her to the promised land and huzzah! It was working!  Soon Shannon's tits had shrunk to about half their mass and she was able to get up off the floor (with some difficulty - those tits were still insanely massive and hung to her hips, which themselves were quite plump now,  to go along with her overall plumper body).  She was still short, too.

Elated over being mobile again, Shannon embraced me in a big hug. Her softness coupled with being enveloped in her giant tits was an incredible feeling.

We experimented all weekend, learning that Shannon's growth was often proportional to the size of my dick at the time.  We eventually discovered that by working herself up to the edge of orgasm, and then letting it subside without finishing, that her body would react and grow more taut, shedding fat and weight in the process.  With a bit of trial and error we got ourselves back into roughly the same size as we were before these strange events started.  I use "roughly" in the loosest sense - I am sporting a footlong cock more often than not while Shannon rarely ends a session with less than double-Ds.

It has been weeks since this incident occurred, with no explanations for why it happened evident nor forthcoming. Nor, thankfully, has the power gone away.  We can still manipulate our bodies with sexual experimentation whenever we like.  I hope this strange power we have never goes away.  There are so many things left for us to try!
