Carter awoke slowly, his limbs splayed out of the bed. He tried to bring his arm down to rub the sleep out of his eyes but found he was unable to do so. Confused, he looked around. His arms and legs were tied to the bed. His cock lay there across his stomach. He started to get hard, a mixture of fear and arousal hitting him. His member inched upwards in size as it got hard, pushing the hair on his abs aside as it grew.
Sam walked into the room and straddled Carter’s chest. He was also completely naked, so his cock and balls rested heavily on Carters chest.
Carter struggled against his restraints as he saw Sam holding three huge needles in his hand. He thrashed wildly but couldn’t loosen the restraints. Carter’s cock dripped a line of honey onto his fuzzy happy trail, betraying his arousal.
“I want you to grow for me,” Sam whispered in Carter’s ear.
“Stop! You don’t know what you’re doing! There’s no telling how big I’ll get if you do this!” Carter cried out.
All Carter could do was whimper and moan as Sam plunged the needles into him one by one. From what he could tell, this was a much larger dose than the one he had given Sam.
The effect was almost immediate at such a high dose. The hair on his body started to grow thicker, his happy trail elongating and connecting with the hair that covered his wide pecs. His pecs began inflating like water balloons, becoming fuller and heavier by the second. He could feel his whole body elongating as he grew taller.
Carter squirmed under Sam as he grew thicker and heavier. His cock, pinned against his abs, began to creep up in size at an alarming rate. It left a trail of pre through his dense hair as it made its trek along his upper abs, making a beeline for his huge pecs.
Sam noticed Carter’s rapidly growing cock behind him and started to lower himself on the slick rod. Sam gasped as the huge head entered him. Carter groaned with pleasure at the feeling. Sam continued to push himself back, impaling himself on the thickening shaft. As Sam’s ass came to rest on top of Carter’s huge balls, he started to rock back and forth on the huge shaft. He could feel it growing inside of him, filling him completely. Sam was dripping sweat onto Carter as they fucked passionately. Carters arms were becoming so huge and thick that the rope was really becoming too tight around them. The same went for his legs, which now hung over the edge of the bed by about a foot.
Sam had to pull himself off of Carter’s cock as it showed no signs of stopping. It was already two feet long and thicker than his arm. Carter’s cock was so huge and heavy it couldn’t stand straight up. It landed on Carter’s chest with a ‘thwack’ and spattered pre into his chest hair and on his face. The enormous cockhead rested on his collarbone now. Carter squirmed against his restraints as he felt the growth seemingly accelerate. The bed creaked and groaned as Carter grew taller and heavier. Sam reached around Carter’s meaty ass and fingered his tight hole. This seemed to really hit the spot, Carter threw his head back in delight and his growth accelerated again. Sam watched Carter’s pecs swell outwards, pushing his half-dollar sized nipples down. The pecs were firm but heavy, so they jiggled slightly as he writhed against the restraints. His abs were like bricks, poking out of the covering of hair on his stomach. Carter’s thick adonis belt formed a beautiful V that pointed down to the base of his cock, where more hair sprouted. Following the cock upwards, Sam saw that the cockhead was now twice as large as it had been, now approaching the size of a large grapefruit. Carter’s cock was now resting on the bedrest behind his head, mashing against the wall as he moved, leaving wet marks on the paint.
Suddenly, without warning, Carter’s cock erupted. Gobs of cum splashed out and onto the wall as his colossal balls seized up and drew closer to his body. His cock shot upwards in length as it grew upwards along the wall. It quickly surpassed the four....five.... six foot mark and was as thick as a beer keg. His balls lurched as they exploded with growth. They were as big as basketballs now, gurgling as they sloshed with cum. Carter kept getting thicker all over. His biceps grew to over 20 inches as he flexed them slowly. His pecs were now so large Carter couldn’t see the base of his cock much less his feet. His traps and neck grew to give him an amazingly thick neck. His shoulders looked like cannonballs.
Carter moaned even louder as his cock reached the ceiling. Sam was in awe of it. Carter’s muscles seemed to have reached their limit as their growth slowed. However his cock kept growing, much to Carter’s dismay. He was lost in the delirium of his orgasm, but he knew this was too big. He would never be able to fuck Sam again, let alone walk. As these thoughts raced through his mind, his fat prick started to bend against the ceiling, needing more room to grow. Carter could only look on in horror as it swelled larger before his very eyes. Carter did his best to angle his groin to the side so that his cock could grow along the wall instead of being crushed against the ceiling. The shaft reeled out even more, passing the 10 foot mark with ease. Carter’s balls were hanging off the bed now, almost resting their enormous weight on the hardwood floor. Carter’s legs stuck way off the bed, having passed the 7 foot tall mark.
Just when the weight of Carter’s cock pressing down on his groin became too much to handle, the growth stopped. Carter and Sam lay on the bed, panting as Sam undid his restraints. Sam was overjoyed by the gargantuan cock. Carter’s cock slowly returned to its flaccid state, still around 3 feet in length. Carter stood up and examined himself in the mirror. His legs were like tree trunks, so thick there was no space between his thighs. His pecs created an unbelievable overhang on his chest. They were so full and heavy that they pushed his nipples downwards towards the floor. His pecs were completely covered by a dense carpet of hair that snaked its way across his stomach and down to the base of his fat cock. He ran his hand through the hair and down his brick like abs. He could feel the weight of his enormous package tugging at his groin. His balls had shrunk a bit so they hung just below his knees. His cockhead brushed his ankles.
“You know what? I could get used to this.” He winked at Sam.
