Oversaturation

 

You did it. You lucked out and were accepted to be part of a drug trial for that supplement company. You were given your first dose and were to return once a week every week for a month to get another dose and a final check-in. You were informed that with every dose you grow a bit more muscular & endowed but could tailor your gains to your tastes by getting off. Every time you get off you'll get just that bit more ripped, a wee bit more yoked, & a smidge more hung.

What they didn't take in account was your lust for growth and your lust in general. Over the course of the month you made it your single-minded fixation to screw, fuck, jerk off, and cum as much as humanly possible to get as fucking much as you possible can of your limited time on this experimental wonder drug. A normal man, including your former self, would have their well run dry quickly with just how much you abused your meat but...this drug, this wonderful miraculous drug, did something to you to keep you always primed and ready to unload at a moment’s notice with each and every instance being more earth shattering than the last.

By the end of your magical month of sex, cumming, & muscle you showed up to the final check-in as a man so radically different from where you began and so, so, so very much larger than any man be they mortal or the most chemically enhanced Mr. Olympia  that you could push anyone one of them to that hair thin edge of making a massive cum soaked mess of their pants (yourself included).

Thundering step after thundering step you make your way to the examination room where you are met by the very surprised of the scientist in control of the trials and his assistant. Before they can collect their jaws off the floor at your size you give them a simple command: "More." The scientist stutters & hesitates so with a single powerful flex you burst out of your thread bare clothes.

Rags fall around you leaving you clad only in your shoes and nothing else. The silence is palpable as all three of you hear a slow and steady drip drip drip noise. Simultaneously they stare down at your inhumanly hard and massive dick (which you've been unable to see for over a week now due to your chest consuming your entire field of vision when you look down). You flex it and your muscles as hard as you can in front of your dumbfounded audience, again you say a single word of "More." and as if to punctuate your point your body responds the only way it knows how to after the last month, it erupts.

White stream after white stream attacks everything in front of you covering it all in a thick layer of your masculinity made manifest. Both the scientist and his assistant are agile enough to get out of the way, but a good half of the room was irreparably drenched in your liquid dominance. As you finally slow down and stop cumming after a few minutes of uninterrupted flooding you stare at the duo silently giving them your command once again as you silently catch your breath.

The scientist stares at you and looks down at your grotesquely monstrous endowment which is no less hard than it was before you deluged the room. You feel your body swell just slightly as if you got a really good pump at the gym and your dick throb a millimeter larger reinforcing how the drug has almost fully run its course through your system. The scientist takes a step towards you and reaches forward to touch your chest which elicits an approving moan from deep within you. Slowly he drags his hand down to your dick and feels how hard it is, how much it is twitching as if you were a single thrust away from repeating your torrent of cum and throbbing of your balls as if you've already reached max capacity and have only the need to empty out to the very last drop. Not even both of his hands and yours would be able to encompass its sheer girth or hope to properly stimulate it outside of your current heightened state.

He looks back up at you and stares into your eyes before giving your dick a single hard squeeze almost pushing you over that edge of bliss and frustration. "Fine" he says and silences his assistant before he makes any objections. He motions for him to go grab another dose and for you to follow him (to a less musk soiled room most likely). Every step you take down the long cold hallway you feel every single muscle in your body bunch up and flex. Every step you take your dick throbs more and more driving you wild as if even the slightest movement of the air would be enough to set you off driving you into an orgasm that will shatter your mind. Every step you take you hear that methodical dripping noise as precums pour out of you with an increasing frequency like an encroaching hurricane of about to destroy the countryside.

Every.

Single.

Step.

After what feels like three eternities you finally get to the room you are being led to...one that is completely unfurnished except for lights and a drain in the floor. Single-minded as you are to get the prize you wanted you don't spare a single thought about it as you're told to stand in the middle of the room and wait until the assistant comes with your new dose. The thought alone is almost enough to send you into another orgasmic frenzy as the dripping from your dick increases steadily. Just as your patience and willpower were about to run out the assistant enters the room and gives the scientist the syringe with that sweet, sweet serum you desperately need down to the very core of your being.

You close your eyes as you feel the slight discomfort of cold steel invading the titanium hard flesh of your arm and that is all it takes. Involuntarily you flex as yet another outburst exits from the center of your soul out of your dick and all over the floor, walls, and ceiling before you.

Liquid power flows through your veins as you cum, both the drug itself and your orgasm fuel even more growth as you swell to an even more cartoonishly pseudo human meat blimp size. Every fiber of your being balloons with more brawn as you ride the wave of your minutes long orgasm. Flex a muscle one moment just for the next moment it grows so much more to leave its previous size looking like a it belonged to a child by comparison.

As suddenly as it began your orgasm and round of growth slowed and then stopped entirely leaving you a sweaty mess breathing ragged but entirely fulfilled breathes. Your entire body twitches and flexes as the scientist looks at you shaking his head. "You got what you wanted and now you have to live with it." he says as he takes a step back towards the door. Before can process what he said your body seizes in a single massive flex as you cum with such force that you're forced back stumbling around the room as shot after shot, liter after liter, is violently expelled from your body. Muscle fights with muscle, body part impedes body part as it becomes harder to move, harder to so much as slightly raise your arm as your forearm wars with your biceps let alone to vainly reach for your dick to try and stymie the unending flow of cum and growth. Uselessly you flail around almost falling back onto your medicine ball sized ass cheeks when finally, *finally*, you stop cumming.

You get a single heartbeat.

Then the flood begins again with a redoubled effort. The hormones and chemicals surging through your body muddling your mind make it impossible to fixate on anything at all except for the unending fountains of jism spraying nonstop from you. The scientist and his assistant smirk as they leave the room knowing that your fate has been sealed and you are now at their mercy for the experiment going forward. Desperately you want to object but your chest has locked you jaw in place leaving you mute.

Each and every muscle in your body is contending for the atoms of space you have left on your frame as you blow up like a balloon left unattended on an air tank. The throbbing of your dick and muscles consumes the entirety of your being drowning out everything else repurposing every sense you have to growth and sex. Your vision grows dark as your mind is truly consumed by the barrage assaulting but slowly it clears and you're able to concentrate little by little as the flow recedes....but right as this mind obliterating orgasm can end another starts, one of even greater ferocity covering your entire front in a thick coating of white as you stumble and hit a wall and fall onto your ass.

 

One Hour Passes

It is never ending. You can barely move and are now at war with your own body. There is no clock in the room, but you guess it’s been an hour, maybe two, now of you stuck like…this. In a single doomed act of desperation, you were just barely able to reach the tips of your fingers to capture your still cumming dick in between your chest, you’re using every bit of strength and mobility you have to try and completely block of the flow but despite your incalculable power and resolve you are losing. A giant mass of cum is just waiting to rail gun itself out of you into, perhaps through, the ceiling. Worse yet is that is incrementally climbing towards freedom and your doom. Frequent geysers and unceasing streams of precum (actual cum?) rocket out and upwards bypassing the otherwise implementable wall of your chest.

 

God knows what would happen if you swallow any of it so here you are….sitting against a wall sporadically shooting or leaking all over your face and body, growing gram by gram thicker, and  barely able to move, with balls acting ticking time bomb to the end of your life as you know it as you delay the inevitable when you hear the door open. Neck and traps too thick to allow you to look aside you don’t move lest you accidentally release just enough pressure to begin the never-ending cycle of growth and cumming again. A scoff and a laugh are heard from a voice you recognize as the scientist. “Dear lord you’re a tenacious one, most of our subjects haven’t made it as long as you have.”

 

Slow footsteps approach you as a deep feeling of dread washes over you. His hand touches your medicine ball thick shoulder startling you enough to let go just long enough to rocket out a spray straight upwards. As your warm cum rains down over you both your body surges just a bit bigger making it even harder to clamp your dick shut, the stream and shot able to slip between your crushing grip increase in frequency and size. He laughs again as he says “Ha! I didn’t mean to make you jump but here let me help you, a little tit for tat if you will.” The sense of dread increases.

 

He enters your vision by standing on top of your colossal quads each of which could easily have enough room for him to stand on comfortably. The first thing you notice is his nudity, the second is that he eclipses the size of some of the most radical porn stars. “Call it a perk of the job. What you think we never get to use the successful stuff on ourselves?” Determinedly he walks closer to you the entire time his over foot long and very full balls are swaying back and forth like a cobra about to strike. A squeal that could be described as “surprisingly girlish” comes out of you as you feel his balls drag over the overbearingly sensitive head of your dick as his own gets closer and closer to your mouth.

 

Flexing his own fairly muscle legs and ass he pushes the tip of his dick into your lips. “Now before you do anything stupid just know one thing. You’re fucked either way. So, we can do this the fun way, or you can sit here and tire yourself out trying to prevent what will happen whether you want it to or not.” Unwisely you find your voice and try to say something, but he strikes at that moment. Choking and sputtering his dick gets halfway into your mouth and down your throat, his ass and balls are maddeningly dragging over your dick head that is just above pec level.

 

He drags his hand through your hair as if to comfort you as he leans down to kiss you on the forehead pulling out a little bit of the thick meat invading you. Both hands now hold your head steady as he plows in with all of his might cramming every inch down your throat in one foul motion. Tears flow out of your eyes as you choke time and time again as he repeats this motion using your body, the body of a god made manifest, as nothing more than his own sex toy. Every thrust drives you further into lust induced madness as your dick is teased by his peach sized balls and volleyball thick globular ass. As if to make its frustration known the flow increases from you as the occasional shot and stream of cum turns into a slow fountain, the wall feels like its moving before you understand actually that the growth has resumed and if he gets you to drop your guard for even a second you truly are fucked.

 

Moans, gagging, slapping flesh to flesh, and the sound of liquid hitting the ground echo the room. The combined smell of musk, semen, and both of your sweat permeate the very air to the point that even if you close your eyes to try and concentrate to hold back the encroaching tide in your loins that is on the verge of breaking through. The scientist moves a hand to hold the back of your head to keep the rhythm going as the other begins exploring every crevice and bulge of your body within his reach. Like a surgeon he slowly and gently traces every vein and fiber always slowly going downwards. His breath is ragged, and you can feel balls throb and jump, his ass is flexing hard and relaxing as he holds off. Mercifully inch after inch of his dick leaves your mouth leaving just the head of it filling your mouth with a slow yet steady river of his pre as he looks you lustfully in your eyes.

 

In one motion the hand that had been exploring you finds your nipple and attacks it ferociously twist and pulling it as his over foot long beer bottle thick cock begins to cum, you only get a brief taste before he smashes it down to the root and your resolve shatters. The massive bulge of cum twice as thick as the rest of your dick dammed by your chest wins. Balls overflowing your lap and resting on top of your knees violently jump and spasm as they draw in painfully before being thrown backwards and back again. Acting like a bilge pump the mass of backed up liquid power pries open your chest and flings your barely clasped hands to the sides as all at once like explosive decompression it all comes out at once.

 

The scientist is unfazed as he keeps drilling into your face while galloons upon galloons of muscle cum flood the room leaving both of you covered completely in a coat of it. Your body reacts instantly and with a vengeance as the growth resumes at an even deadlier rate than earlier. Scared and with your mind being overstimulated to the point of shutting off all senses but the growth and cumming you struggle to grab your dick, and fail, to get up, and fail, to do…anything but all in failure. All your attempts to stop the growth are in vain as all you can do is fall to your side, dislodging the scientist’s still hard but no longer cumming dick out of your mouth, and try to get up like a drunken turtle on its back. Content with a job well done and from using you like a muscle blimp of a condom to be thrown to the side the scientist leaves you to your fate.

Muscle impedes muscle as your body pushes itself away from the wall as you grow. The only movement your body is capable of now is the jerking motion of your dick as it jumps high into the air to then smack your forehead as its movement is stopped by your couch cushion thick pecs. Every blast dooming you a bit more to your fate. As soon as it feels like your about to stop the cycle of cumming and growing and finally finish this unending orgasm another starts before the previous ends. The world and your life are naught but a distant memory as they have been completely replaced with your new reality. Every blast destroying what is left of your mind as your entire reality is subsumed by the one and only thing you are now capable of.

You cum.
You grow.
You never stop.
You get what you wanted.
You never wanted this.
You never want this to stop.

Overstimulation

 

 

 

An unknown amount of time later

 

 

Muscle.

Cum.

Muscle.

Cum.

Muscle from cumming then more muscle and more cumming.

 

 

Your mind has been shattered leaving you barely conscious of where you are, what time it is, and just the vaguest memories like half remembered dreams of who you were before your life, as much as you can call it that, became what it is now.

 

 

Muscles so grotesquely gargantuan, no even that isn’t a big enough word for it, and all consuming that now you can only just barely move your hands and feet. Even they are impeded by the adamantium hard flesh encompassing literally every last nanometer of room your body can hold. Much to your relative relief the growth stopped eventually once you hit this limit averting a much worse fate. Now you’re a prisoner both in the metaphorical sense by your body and the literal sense due to the bastards that gave you those drugs in the first place. After some time had passed the scientist came back to check on you and give the down low.

 

 

Those shots you took? Worked as intended but your greed and lust for more “twisted their arm” to put you into the “advanced pay back program.” The last drug was a catalyst reacting to the month long latent build up of the drug you took. Your reaction to it and your decision to just go fucking hog wild only made the catalyst that much stronger when you were injected and so you are now their prize bull. Almost literally in the sense that you have one purpose now. He says all this as he slowly starts attaching tubes and injections into your near room sized body. You’re to be milked of every single drop of cum your body is more than eager to produce.

 

 

“Not to worry though we’ll take good care of you” he says as he gestures to the various tubes. “Every need your body has will be taken care of and believe you me you’ll need a constant stream of calories to keep that body going” he quips while slapping your calf the size of his torso as he chuckles to himself. He presses a button on a remote and a tube as thick as a barrel is lowered from the ceiling towards your dense as diamond monument to masculinity. Slowly it lowers itself foot by foot easily engulfing your weapon of mass dickstruction until it finally rests on top of your thick muscle gut and groin. Another button is pressed as you feel suction begin as well as two separate rings working in tandem to drive you to the edge.

 

 

The doctor gives you a satisfied look as he opens the door allowing his assistant to enter the room. They both watch as the rings speed up faster and faster, the hum of the suction increasing more and more forcing even more blood to bloat up your dick to painful levels. The scientist tosses the assistant the remote and heads out of the room while saying over his shoulder “Enjoy those perks I mentioned, I know for a fact he loves to face fucked hard.” You’d give him a death glare, but your head has long been consumed by your neck, traps, and chest leaving the ceiling your only companion.

 

 

Silent hums from the machine having its way with you and unintentional moans escaping from your lips are joined by the loud sound of a metal belt buckle hitting the ground. The sound of steps approaching your head, the remote making a sound as another button being pressed, the machine going into overdrive. You ball your fists and curl your toes as the nefarious machine gets you to the precipice of orgasm and leaves you there, not one step over or before it. Steps come closer as the machine starts to have issues working as you feel your dick thickening even more pushing this monolithic tube to its breaking point as it heinous work continues unbated. Your ball sack so full, heavy, and monstrous in size that is pushes your immovable legs apart to make room for itself begins to churn and seize. The steps stop and you see the assistant…or to be accurate you see his dick first hovering right over your head and him second.

 

 

He gently caresses your face and plays with your beard (Wait…how long have you been here? You didn’t have a beard on that fateful day) as he stares into your eyes. Accepting your fate, you open your mouth as much as possible and he smiles as he slowly pushes it into you. While not as large as the scientist you still struggle to take it as he gradually gets rougher with you. Bending down you hug your king size mattress wide chest he humps your mouth, his pendulous balls bouncing onto your forehead, and starts licking and groping everything in range. Your balls are throbbing and percolating angrily as all your precum is being sucked out directly by the machine destined to go gods knows where. Just as you’re about to begin crying in frustration and need he presses another button on the remote, without dropping a beat as he has his way with your mouth, and you feel the rings stop and suction slow to a teasing amount.

 

 

Precum pools around your dick in the tube as you cry out between gags to just let you cum, but he continues to tease you as he fucks your throat. Your balls and dick throb, twitch, and seize hard trying to push you that hair over the edge you need to finally let loose your salvo as the level of your precum pools up halfway the up the tube. Humping of balls to forehead and moans ring out through the room eclipsing all noise as you spurt and jettison precum in amounts surpassing a sex addict yearly amount of cum. Tears well up in your eye as you, the definition and god of all things masculine, are about to weep openly to please get some release. As your elephantine multiple feet long cock is fully submerged in a pool of its own precum the sound of the remote chimes again. Simultaneously the rings stimulating you move with such a ferocity as if they’re trying to start a fire and the suction begins anew with such a force you feel as is all the blood in your body is being force into your dick as it swells to the absolute max capacity of the tube. The ocean of pre is gone in a flash of white as you feel another oceans worth travel up your dick.

 

 

The impending biblical flood is so monumental the assistant can see it visibly making it’s exit out of you and with that he pushes a button one final time. In abrupt motion the nearly broken tube goes back into the ceiling as your dick tenses up backwards before relaxing with the first of many, many wall destroying blasts lowering itself down…right into the assistant’s waiting arms and mouth. He clamps his mouth around the slit of your dick just as the first cannon salvo exits and he greedily drinks it down showing off his years of chugging skills from college.

 

 

You let out a combined scream, moan, and sob as yet again everything goes dark with every shot leaving your mind to attempt to reboot in between volleys. The effects on the man are instant as you feel his lithe arms wrestling with your bucking bull of a dick become infused with such brawn as to easily chokehold it into place. Strips of cloth rain down onto your sweat and cum covered face as his torso surges outwards so violently as to explode it off. His stance widens and you begin to hurt as his balls grow to the size of oranges, his legs into pillars of perfect marble, and his dick stretches your mouth and throat in every direction as it drills further into you. Flailing your hands and feet, bother suspended in mid air by the sheer mass of your calves and forearms, you struggle to breathe.  Like a god damned champion, he doesn’t let a single drop escape his insatiable mouth as your vision is blocked by his chest and then his cum filled muscle gut. Slipping in and out of consciousness to the place in between the reality and nightmares you see and feel this man inflate to levels unknown by mortal men (prior to your “overdose”) as the minutes go by.

 

 

Eventually even your inexplicably gargantuan manhood runs dry though a dry orgasm runs unabated nonstop as any fluid that is replenished is immediately expelled directly onto the chest of the giant you involuntarily made. With a final thrust his dick swells as it spews with a newfound vigor all of its content into your air sealed throat. You struggle for breath as you watch the assistant’s gut recede and turn into stain steel bricks perfectly arranged upon each other, his chest now shadowing your face and blocking any other sight of this demigod that used you for his ascension. Just as you are about to pass out, he finishes cumming and has to take a few steps back to fully extract himself from you.

 

 

With a deafening THWACK his wine bottle steel girder of a dick stands directly up throwing saliva and his cum everywhere over the two of you as the head of it gently lodges itself in the mountainous horizon that is his chest. He pats you gentle on the cheek before bending down to kiss you on the mouth, his dick lowering with him right between your eyes, as he gives you a satisfied look and says in a voice as deep and resounding as an oncoming thunderstorm “Hell of a perk, isn’t it? Looks like you’re going to be our prize bull and make us so fucking much serum.” Frantically you instantly realize he meant your cum and that you were forced to drink a good liter of his. Fearfully you brace for more growth that you doubt your body will survive. He laughs, pats you on the cheek again, and presses the button to restart the milking process all over again. Slowly you watch his medicine ball ass cheeks leave your vision as it hits you hard that what he is now is what you wanted to be…not this meat blimp being used like a livestock stud.

 

 

The door opens and you hear him kick away his now severely too small pants away as he leaves you to your fate. “Don’t worry I’m not a producer like you are so all you got was a good time. Thanks stud.” He says with a slight bit, “Enjoy the stable and I’ll be back later maybe for another ‘perk.’” A chuckle is heard as he closes the door. You feel a single tear roll down your chiseled face as the machine begins milking you again. “God damn it.” Is all you can say before another mind shattering orgasm throws you back into the inky abyss doomed to you muscle and cum filled fate.

 

 

You cum.

You never stop.

You got what you wanted.

You never wanted this.

You never want this to stop.

[an0n12]

I edited and altered the first part so I assure you it is worth a second read if you already have.

[WoodenStick]

Dayum! 

I wish it was me! 

I'm that amazed by this story that i dunno what to say besides: I want it happen to me right now. 

I love this story as well like all stories you done! Greetings to you!

[Guest]

Found this story. Incredibly hot. Would love a third part of more people coming for "perks", maybe eventually they set him free as be turns and overstimulates everyone else?
