(Took a little bit from an older CYOC story, can’t remember which, and added from there)

He slams the door shut behind you and sits you on his lap as he sits his muscular ass on the closed toiled lid in the guys bathroom. He then reached out with his right hand and began groping one of your ass cheeks, as you began feeling along his muscular black arm. You squeezed, but couldn't hurt his steel-hard bicep, then he flexed it for you. The large ball of muscle jumped out and you gasped, "Wow. You're so strong."

 

"Fuck yea I am bitch," replied Carlton in a dominant tone. He pulled away from your ass to reach up and fully flex both his incredible massive arms. He had decided to take you to the bathroom stall to fuck you in private, cause he’s straight, or so you thought. Because with how eager he was getting into the bathroom alone with you, you were beginning to have second thoughts. He then flexes both of his incredibly massive bit ps again, only this time a little harder. You look up at his imposing black form as he sits on the toilet lid in the bathroom stall and you on his lap. His arms looked even bigger. "Go ahead and feel em fag'." He smirked and looked at his own impressive limbs. 'They do look bigger,' he thought. 

 

While you continued to worship Carlton’s bulging right arm, you began making out with the god stud and teasing his large black nipple at the same time. You were trying to straddle his wide left thigh and pressed your chest against his, but for some reason you were having difficulty getting positioned, almost as if as soon as you found a comfortable position, it instantly went away.

 

Suddenly, Carlton felt very uncomfortable in his xl boxers. He pulled his tongue out of your mouth long enough to say, "Fuck nigga it felt like my pants just got tighter." 

 

You then placed your hands on his thick right pectoral and then moved them down his cut-up eight pack to his sick atlas lines. You begin to anxiously undo his pants and pull them down, and was not surprised to see that the muscle jock was wearing his Calvin’s. Carlton’s thick black god cock sprang up to a full 13 inches and throbbed with as many veins as his vascular arms. And below that, big black lemon sized balls pumped testosterone and hormones into is godly form. The wide root was hidden by a  large amount of black hair that was framed by his incredibly muscular thighs.

 

You gasped at this porn-star sized dick. "Oh my god. You're big," you said, sounding incredibly aroused. 

 

"Fuck yea I am, I’m a huge fucking black god!" said Carlton who was too entranced with his own muscles to notice he was a good inch longer than usual and that his voice was slightly deeper. You then began swallowing his huge veiny black cock down your throat, “Fuck, that feels sooo good." The feeling of his fat black head deep down your throat made him shudder. He puts his hand on the back of your head and forces your head down it further. You start sucking, and are surprised, but not really, to feel him shove his cock deep down your throat so far as to where your nose is smashed up against his body. But then you feel him do it what seems like a second time, only much further, even though he never pulled out between thrusts. You then feel like his cock is quickly being filled up like a balloon as it fills up your mouth and throat to an unreal level.

 

As his cock throbs bigger in your mouth, you feel Carlton’s already massive nuts begin to surge bigger underneath your chin. You reach up with both hands to feel that they have grown to each being goose-egg sized stuffed in his underwear. Once your hands, through the fabric of his underwear, make contact with each of his giant nuts though, Carlton stretches out and bulges your throat and mouth so full with his, now 20in and increasing, god cock that it begins to stretch past humanly possible. And you begin to worry he could tell that.

 

“Oh fuck me that felt good, but don’t do that again, my huge balls are sensitive and I don’t want to outgrow this stall just yet.” You looked up at him in extreme arousal after hearing what just left his mouth. “Yea thats fuckin right fag!” He said looking down on you “choking” on his huge black dick puffing out of your mouth with size and power bulging all the way down to your throat oozing pre into your stomach. 

 

“I found out you are magic and can grow people with your arousal a while ago. But then I also found out that you are attracted to dominance, and well... you know me” he said as he made his big muscular pecs bounce. “And then I caught you sneaking looks at me in the dining hall and I knew, I fuckin knew I was going to become a fucking massive muscle god!” He looks down at you and flexes all of his bulging black muscles. Your cock then begins to weep pre from how hot he’s making you as you feel his junk bulges even more inhumanly large in your throat and beneath your chin. You see his muscular form then begin to take up so much space that his massive muscles arms are now touching either side of the green bathroom stall. Seeing this too then made you repeat the process as you see his abs tighten and bulge to the size of your fists as you heard a a much deeper version of Carlton’s voice escape from his quivering lips above you “Holy Fuck it feels so fuckin good, everything feels so incredible and incredibly fucking powerful...” The black god is left awestruck with his growing body and begins to feel himself up.

 

Meanwhile you continued without success to get the god to cum but Carlton only said, “Its gonna fucking take a lot more than that to make this BEAST cum!!” So you then hoist his now massive throbbing hard cock out of your mouth and began to guide it into your ass. The waves of pleasure were so intense you couldn't even concentrate completing on your self-appointed task of fully stuffing his tremendous manhood all the way in. "OH FUCK. I feel so big. So buff. I'm a huge fucking stud. Yeah." The young god grunted, enjoying his new size. Beneath you, His big black balls slowly bulging and inflating to the size of grapefruits. Carlton had left his balls in his Calvin’s cause, one they were the most sensitive part of his body even when they were at their original size, and two he liked to see how even with his god cock out of the underwear, he can still see his two giant black nuts stretching out his underwear when he fucked someone sitting down. And now he was certainly going to see that, cause tears on Carlton’s underwear begin to form as his bulging growing black god balls fill his xl Calvin Klein white underwear to the tearing point. His immense thighs became so defined that the teardrop shape grooves were impossibly deep

 

Carlton had started out as an, albeit above average, college alpha god stud black muscle jock, but was now a 8’10" overly muscled heavyweight bodybuilder with a twenty five inch cock. The beastly muscle nineteen year old moaned louder as he felt your tight hole growing smaller and smaller around his ever expanding black monster. "Oooh. So Fucking TIGHT BITCH. I'm too fucking GODLY AND HUGE. Yeah. Huge Muscle jock."

 

You looked down and watched as his shelf-like pecs ballooned out, the cleft between them ran deep. His massive shoulders stretched to three feet wide, close to the size of bowling balls now. You felt his expanding abs pressing hard against your naked butt. His huge thighs continued to push your legs even wider and his head began slowly growing further away. His now incredibly muscular black body was completely filling out his stretchy workout shirt and shorts with massive muscle and black manhood. So much so to a point you could hear and see tearing coming from the fabric. His size fifteen 1/2 shoes explode off his humongus black feet.

 

You sat on his immense thighs, having now takin Carlton’s 30’ massive cock. The feeling of his growing black veiny god cock was intensified as Carlton made a really orgasmic face and a massive involuntary thrust came from the black gods groin as his now obscenely massive nuts that were falling out of the sides of his underwear swelled massively and destroyed their previous confines flooding the god with testosterone as his body then throbs even bigger and more muscular completely destroying what was left of his clothes and leaving his growing muscular ass to begin engulfing the toilet seat. Carlton then gets harrier in certain places especially his armpits and around the base of his monolithic tower of a cock. His rich hot musk begins to fill the room, but apparently, this kind of power was not intense enough for the ever gaining power muscle jock. Carlton began lurching and thrusting his enormous, muscular haunches, as waves and waves of infinite power begin to flow into him, lifting you higher into the air. Wracked with pleasure he reaches up with his enormous black arms and grabs hold of you. You look down and yell to get his attention. His arms are now gigantic. Carltons thick bulging black forearms are bigger than your waist and his bicep peaks are easily 38 inches. 

 

The yell wakes Carlton from his pleasure dream and he lets go of you just as the god throbs bigger and the toilet collapses under the muscle giants steel-hard ass. Carlton looks down at his 10’3", 750 pound body and grins. "Shit, I am fucking huge. I'm a FUCKING MUSCLE GOD BLACK BEAST! I’M SO FUCKING STRONG I COULD DESTROY THIS BUILDING!," he yells. He then notices you, still thrust upon his now 40 inch god black cock, now looking extremely horny. He laughs at you and begins flexing and feeling his huge muscles “FUCK YEA, Make your big powerful god fucking bigger and MORE POWERFUL!” Carlton’s muscles are so massive that he takes up most of the restroom with his big black imposing god form. 

 

The giant young black god then stands to his full height, his head bumping into the ceiling, with you still impaled on his twitching thick black monster actually suspended in the air. Carlton begins to flex his huge body. “Maybe if I flex harder and show more dominance it will turn you on more.” He says hitting a double bicep pose, he laughs at the enormous muscle peaks which are bigger than your head throb and swell magnificently. "OH FUCK! GUESS FUCKING SO!” he booms. "I'm so FUCKING HUGE. I'm the biggest fuckin nigga on the fuckin planet. I fucking love being such a HUGE FUCKING MUSCLE GOD." 

 

Carlton begins to laugh and revel in his power  as you quickly jump off his dick as much as you don’t want to, but you don’t know how big he’s about to get. He hits a few more double bicep poses flexing his guns and admiring how huge and godly his body now was. And while doing so he begins to stagger to the ground as if trying to hold a bolder above him as power pours into his being. All the while with each stagger, different parts of his godlike being throb and pulse outwardly larger and bigger, and especially more girthy. His ampit hair grows denser and hotter as his biceps bulged stronger and bigger, followed by all of his other giant black muscles. Carlton’s dick throbs bigger comparatively to his muscled black body, and underneath, Carlton’s massive nuts are gaining even more size to keep up with his huge black dick. 

 

Being the cocky black god that he is, Carlton wants to feel the power that each of his balls contains. So with his massive hand he tries to cup one of his balls, manages to get his hand around enough to hold it, but barely able to keep from having it fall out of his hand from the sheer mass of it. Carlton then gives it a squeeze, and not a moment later than when he did that did his massive godly body surge with incredible size and strength completely filling the entire boys bathroom. “Fuck yea I’m a fucking god nigga” Carlton said in his deep voice under his breath. “I’m gonna be a FUCKING GOD!”. He squeezed it again, then again, and then again, completely destroying the bathroom and building with his growing form all the while his bulging cock head just oozed his cum onto the ground beneath him covering some trees, then some buildings, then all of his College campus, each throb of growth induced by Carlton made him shoot his thick god load in larger and larger quantities. Carlton then squeezes hard on both of his giant powerhouse balls and in one giant surge in both size and cum, he begins to dwarf the biggest skyscrapers.

 

The black muscle god works himself into a flexing frenzy, actually getting turned on by his new size as his body continues to expand, gaining infinitely more power to make Carlton into the muscle god he was soon to be. The biggest bodybuilders would look like dust compared to his godly form. his gigantic pecs engorged with power and bounced with every flex. Your entire apartment was the size of any of his amazing 10-pack. 

 

"OH FUCK. IM SO FUCKING BIG, AND IM ONLY GETTING FUCKING BIGGER, SO FUCKING MASSIVE. YEAH. SOON ILL BE A FUCKING GOD, OH FUCK!” Muscles bulge all over his body, “GONNA FUCKIN REALLY FUCKIN CUM!!!" His giant muscled frame exploded with veins and pumped up to unbelievable proportions as his entire body flexed at once. His incredible already inhumanly deep voice jumps down an octave as his deep godlike moans begin to rumble everything around him. His orgasm was so powerful it actually covered all of the city.

 

As the black giant muscle god surged bigger and more powerfully into the sky, you decided that you wanted to see Carlton become the Ultimate God. You then wished that Carlton would gain so much power and godly muscle, that he would become an actual god. Carlton’s deep moan then stopped. He looked down at you in confusion and almost anger because his godly body had stopped growing. Carlton’s entire black god body then lurched and began to rise up off of the ground. His big bulging black muscle body and huge black god cock and balls began to obscenely inflate. His powerful bulging muscles then seemed to shrink for a moment, but then get ten times bigger; You notice that this is happening because they are only beginning to get infinitely denser and stronger as his huge black cock head began to ooze thick ropy cum. “YEESSSSS!!!” Carlton bellowed in his newly godly deep voice. “MAKE ME YOUR GOD!!!!” Cartons huge bulging form began to gain more and more power as the sky around him began to twist and warp due to the sheer density that Carlton’s godly body now possessed. With a huge typhoon of god cum that explodes out from his increasingly growing black dick head protruding from his exponentially growing black muscle god body, Carlton’s deeply godly voice booms, “WHAT THE FUCK ARE YOU WAITING FOR NIGGA!?!?!MAKE ME YOUR FUCKING BLACK GOD!!!MAKE ME THE FUCKING GOD OF EVERYTHING!!!” 

 

You then concentrate all the energy and power around Carlton and begin to force it into his growing godly form. The black god looks down at you with an extremely dominant and almost evil grin. The black god then grabs his titanic bulging cock with both of his hands and starts to stroke it as power from all around him rushes into his being. With each orgasmicly struggled stroke the massive black god made, deep from within his giant cock comes a shudder that runs through Carlton and with that, the black gods muscle body and cock and balls bulged titanically, his muscle becoming infinitely powerful as his black godly deep voice drops even lower and gets louder and louder as all you can hear is something of a deep bellow like orgasmic moan come from the god Carlton’s muscle throat “SHIT NIGGA!!! FUCKIN SHIT NIGGA!!! SO MUCH FUCKIN POWER!!!”He then reaches back down to his balls as another powerful wave of growth hits him. “MORE NIGGA!!! MORE FUCKING POWER!!!”Carlton’s muscled twitched and bulged. He starts rubbing and needing and squeezing his big black balls with an almost brain dead look on his face as his hot lips hang wide open and drool and his eyes roll into the back of his head from the amount of orgasmic pleasure running through his bulging throbbing body. His cock starts spewing an endless stream of cum like a fire hose turned on full blast as he expands in all directions exponentially with muscle, size, power, and masculinity as his huge black body becomes buffer and stronger and bigger and more powerful then the fucking earth.

 

Carlton then begins to shove his god cock into the earth as he feels another extremely powerful surge of growth come from deep within him. “OOHH FUCK ME!!!”Carlton’s entire being then surged bigger as his cock began to tear the world apart. His body siphoned in the earths energy through his cock as he held onto it. His big bulging muscular ass began to encroach the moon and completely encapsulate it. The giant black muscle god felt this and his asshole twitched as he crushed the moon between his ass cheeks and absorbed it’s energy. The black god moaned as the energy’s power flowed into him and his cock began to twitch and expand inside of the earth. This was followed by a large throb that cause his dickhead alone to grow bigger then the earth as he was filled with exponential godly power.

 

Carlton then began to expand in all directions as his muscular black body packed on more and more size.

 

BIGGER!!! FUCK YEA FUCKING BIGGER AND MORE GODLY!!!! YESSSSS!!!!! I AM THE FUCKING BIGGEST THING IN EXISTENCE!!! AND IT’S ONLY FUCKING GETTING STARTED!!!”

 

Carlton’s thundered in his omnipresent voice as he got so massive and powerful that his black god piss slit was infinitely bigger then the observable universe, and then he exponentially grew bigger in constant spurts with each spurt infinitely growing him bigger and more powerful then the last.
