A Run Around the Track

“C’mon Rob! You keep complaining how coach wants you bigger. I think I have the solution!” Alex said in an overly chipper voice.

“You were just supposed to help me study,” Rob growled at his tutor. He didn’t understand why Alex would have wanted to meet him around the college track. But it quickly started to make sense. “Or are you just trying to get a chance to watch me workout?”

Alex’s tilted his head with a devious smile. “No…” He lied. Both of them knew it. Alex had been watching Rob like a hawk every single time they were would go to the library. His eyes would trace Rob’s body every chance that they got. “I’m just trying to be helpful.”

Rob’s eyes narrowed. “Where’d you even get this stuff?” The container wasn’t labeled, and it looked like a generic protein powder.

“Online. Everyone who reviewed it said it had amazing results!” Alex answered. He was already scooping the powder into a shaker bottle. Then added water to it. The substance dissolved instantly, making it look like it was just water again. Alex stuck out his arm. “Here!”

Rob stared at it skeptically. “Is it safe?”

Alex shrugged.

“YOU DON’T KNOW IF IT’S SAFE!?” Rob shouted. A few people walking the track looked over at them. Rob slapped his face. “You have to be kidding me…”

“I don’t know… How bad could it be?” Alex said. “What’s the worst that could happen? You get a protein powder that doesn’t do anything? Isn’t that normal?” He shook the bottle. “Come on… People said they see results after a few minutes.”

“Fine…” Rob snatched the shaker bottle out of Alex’s hand. He was tired of Coach Albarn saying he wasn’t putting enough effort out on the field. Like Alex said, ‘what’s the worst that could happen?’ Rob downed the drink.

Alex stared at him skeptically. “Anything yet?” Rob shook his head no. “I think they said that you have to build up a little bit of a sweat…”

“If this doesn’t work,” Rob stuck a finger in Alex’s face, “you’re doing all my homework. Got it?”

“Got it!” Alex squeaked.

Rob started off for a bit of a jog. It was just a standard warm up. However, even as he rounded the first bend of his first lap, he could feel sweat starting to drip down his brow. His heart was beating faster and there was this odd sensation running through his body. Rob powered through. There was no way a something could work that fast.

Then there was this odd feeling with his shirt. ‘It’s just the sweat,’ Rob reasoned as it clung to his chest a little more than usual. He could really feel the wetness running down his chest and back. Whatever this was, really made him sweat. Even he could smell the musk wafting off of him as he ran.

As he rounded the second bend, now his shoes were feeling tight. ‘There’s no way…’ Rob thought to himself. Had he really been growing? It didn’t make sense. Maybe a rock just got into his shoe or maybe he accidently picked up the wrong pair or one of his friends was playing a prank on him.

Rob finished his jog in front of Alex. “How’s that?” Alex didn’t answer. His mouth just hung open in shock. “What?”

“You—you got bigger…” Alex stammered.

“Huh?” Rob looked down at him in confusion. There was no way. That was barely even a few minutes of light jogging. It didn’t make sense, though as he looked down at Alex, there was a clear noticeable difference. At 6’1” he’d always been a bit taller than the other man, but now Alex barely came past his shoulders. “No way!”

“Yes way!” Alex cheered. He clearly loved looking at the bigger jock right now. There was so much more to gawk at. Now Rob’s shirt was starting to rise up and show off the bottom layer of his abs. His biceps looked so swollen that he would have a hard time finding anything that had sleeves. He’d probably have to get custom made pants to properly fit his enormous, but perfectly sculpted ass. 

“This is–!” Rob let out a grunt. His body seemed to have collapsed in on itself. Every muscle was flexing.

“Rob?” Alex asked.

Rob couldn’t respond. Only grunts came out of him as he felt his heart absolutely racing. Each and everyone of his muscles felt as though they were on fire. It was all at once too. He clenched his chest. Veins bulged out of his skin. And he started to grow.

It was a sudden burst of power flowing through him. His athletic body was rapidly doubling in size. Muscles grew at an unprecedented rate as he writhed under the weird feeling. The sleeveless shirt didn’t stand a chance. His widening back and chest ballooning out in front of him made the XL sized shirt look almost kid sized. It was the same with his shoes as his toes pushed out of them. Then crushed the remnants of the shoe’s soles.

“F-uck… F-uck…” Rob panted as he slowly regained control over his body. He looked down at his massive mitts for hands. Then quickly realized just how much further down the ground was from him. Getting a look at Alex, the other man barely came above his waist.

“R-Rob?” Alex stammered. “How are you feeling?”

Rob huffed out a few more deep breaths. A new emotion was emerging. He couldn’t understand it. He didn’t answer Alex. Instead, he picked up the small man by the collar and started carrying him.

“I’m sorry! I’m so sorry! I didn’t realize it’d make you this big! I thought it’d just make you a little bit bigger!” Alex squirmed in the giant’s grasp.

Still, Rob didn’t say anything. He ducked under the doors and went into the empty locker room. He held Alex up against the wall. Then kissed him. Once the confusion disappeared, Alex was happy to reciprocate. Their tongues wrestled as Rob held Alex up against the wall.

Alex’s hands happily roamed around the unbelievably hard muscles of the hulking giant. He squeezed Rob’s pecs and traced the outlines of his hard muscles. All the while, Rob’s hands were quickly finding their way into Alex’s shorts. A finger popped into Alex’s asshole.

“Ahhhhh…” Alex moaned as he broke off from the kiss.

“You like that?” Rob moaned. His finger continued to wiggle around, tickling the other man’s insides. “Huh? You like making me into this big hulking monster?” Alex couldn’t respond. His mind was all over the place in a lustful haze. His little hands squeezed against Rob’s body for support before finally giving up.

Alex’s body jerked. A wet stain started to form in his underwear and bleed through to his shorts. He rested his head on the massive chest before him, taking in all of the other man’s musk.

Rob let out a frustrated grunt as he set Alex back down. The little guy continued to cling to him. His body rubbed up against the massive cock still straining Rob’s shorts. Alex took his own initiative as he lowered the hulking man’s shorts.

“At least no one can say you aren’t big enough…” he smirked as he used both his hands to properly jerk off his giant.
