“Hey man, good to see you again,” Parker smiled as Neil opened the door, clad only in his underwear. The gymnast bit his lower lip as he openly ogled Neil’s powerful physique, eyes widening as his gaze reached the hefty bulge in the larger man’s hastily donned underpants.
“You too,” Neil smiled back as he let Parker in, “You ready to get freaky with a couple of horny musclemen?”
Parker laughed at that, pulling off his shirt as Neil closed the door behind them. The gymnast’s body was compact, but packed with lean muscle. He wasn’t close to Neil or Brock’s size, either in terms of height or muscle mass, but he was still very well built, even if the top of his head only came up to Neil’s chin. “So,” Parker said, as he unbuckled his belt, “I happened to be at your gym today. There was a bust pipe in our training space at the university, so Coach sent us over to 20 Fitness, even if it doesn’t have much in the way of gymnastics equipment. I think he knows the owner or something. Saw you and a couple other big guys there, looking hot as hell.”
“We fucked in the steam room afterwards,” Neil smirked, “you should have dropped by! But I guess we have time to make up for that now. Just Brock and me, though; Lucas is with his girlfriend or something.”
“Really?” Parker gasped, eyes widening. “Right there in the sauna? Are you kidding me?”
Neil laughed. “No joke man. We were horny as fuck! And Brock and I still haven’t gotten it out of our systems yet. You’re in for quite a ride!” He guided Parker back toward Brock’s room.
“What do we have here?” Brock grinned as Parker stepped into his room. The hulking bodybuilder stood up from his bed and strode toward Neil and the gymnast. Parker’s jaw dropped open as he took in Brock’s sheer size. “Let’s help our guest finish undressing,” the big man purred to Neil. Together they helped pull down Parker’s jeans and underwear, leaving him nude between them.
“So,” Brock growled, straightening, “What kind of dirty fantasies bring a cute thing like you into bed with a couple of meatheads like us?” The grin he directed at Parker was positively predatory.
The gymnast gulped, but then piped up. “I want to be fucked by you! By both of you! At the same time, if possible!”
“No way we’re both fitting in you at the same time,” Neil laughed as he pulled off his underwear, his huge erection bobbing free. It was ten inches long, fantastically girthy, and had a pair of hefty, full balls filling the sack that hung below it.
“Don’t be a defeatist, Neil!” Brock chided. “You take him from behind, I’ll take his pretty mouth!”
For a long moment Parker stared in shocked silence. But that was all the time it took for his half-hard erection to go full mast. Brock grinned and sat down on the edge of the bed, spreading his huge legs wide, displaying his hard cock and shriveled sack. Parker got down on all fours and approached the edge of the bed. He ran his hands over Brocks’ massive thighs, caressing the large trunks of muscle while kissing and licking the hulking bodybuilder’s cockhead, lapping up the pre that gushed from it.
Neil got down on his knees behind Parker and kneaded the gymnast’s athletic glutes, massaging the rounded masses of muscle. Parker let out a low moan which only ended when he dove onto Brock’s cock, taking the entirety of it into his mouth in one go. “Hungry fucker,” Brock crowed, grinning ear-to-ear.
Neil felt his own sexual hunger rise. He continued to work over Parker’s ass, producing muffled groans from the smaller man. Then he got in closer and pushed his cock between those firm glutes, teasing Parker’s hole with his tip. “Oh fuck, please fuck me!” the gymnast gasped, briefly coming up to speak before diving down onto Brock’s tool again.
Neil didn’t need to be told twice. He slid into Parker slowly, gradually opening up the tight tunnel that he invaded with his oversized cock. The way that the gymnast moved under him let him know that he was hitting all the right spots. Neil began to fuck Parker with strong, steady thrusts, confidently slamming himself against those perfect glutes over and over again. He felt a flutter of change hit his body--nothing too serious, just the feeling of his muscles becoming a little stronger, a little larger. He looked down and could see that Parker was changing too. His lean body was becoming more muscled, but in a way that kept that gymnast’s physique--just a stronger, more developed version of it than before.
Feeling Parker’s glutes develop pushed Neil over the edge. He let out a loud groan as he came, his big dick pumping the gymnast full of Neil’s seed. He pushed his spasming cock in deep, holding it there as it emptied his load.
The young bodybuilder’s eyes widened as he looked up. Brock’s head was tilted back, his closed eyes directed up toward the ceiling. He was clearly bigger, every ‘roid-blasted muscle larger than ever. But that wasn’t what caught Neil’s eye. Rather, it was the fact that the older-looking man had developed a short salt-and-pepper beard but otherwise was nearly bald. He looked like he was in his mid-50’s, his appearance screaming ‘muscle daddy’ more than ever.
Neil pulled out of Parker, falling back on his own mighty ass. He couldn’t help but stare at Brock, shocked by the changes. The big man’s head swiveled downward and his eyes opened. “Ah, a vacancy,” he growled in his deep voice. Suddenly he was lifting Parker up into the air as he got up off the bed. For a brief moment, Neil got a good look at the other man’s equipment and noticed another big change: although Brock’s sack was still diminished, his cock looked considerably bigger than Neil remembered, mainly in terms of sheer girth.
Using his considerable strength and taking advantage of Parker’s fantastic flexibility, Brock lowered the gymnast onto his broad cock, a look of bliss coming over his middle-aged face. “Neil got you loosened up nicely,” he growled, “but now you’re going to be BRED.” What followed was a truly impressive display of sexual athleticism and power as Brock thrust up into Parker with a series of energetic thrusts, jackhammering him with more force than Neil would have even considered.
Yet that barely registered with Neil. He was completely fixated on tracking the changes to Brock’s already-huge body. The man’s already oversized muscles became truly bloated with power, freaky veins rising up under every surface. His face aged slightly, the last bits of hair on his head vanishing, except for his eyebrows and beard. Those both became grayer while the latter also grew longer and thicker, his short beard replaced by a full set of facial follicles. Out of the corner of his eye, he saw a large penis pump on the nightstand; surely that hadn't been there before, had it?
When Brock finally came, he let out a mighty bellow as the last bits of pepper vanished from his beard, leaving it solid gray with a few paler strands mixed in. His mighty chest rose and fell as he took deep breaths, recovering from the exertion of fucking Parker in that position. When the last drops of ‘roided spunk had been deposited inside the gymnast, Brock slowly lifted him up and off of his thick rod, turned, and carried Parker over to the bed. He set the smaller man down gently, then stepped back, a grin breaking up his gray beard.
“That’s decades of work in the gym, boy,” he boasted, his voice deep and rough, standing at the foot of the bed, looming over Parker. He raised his massive arms and flexed them hard, mountainous biceps rising at his command, flanked by huge deltoids and brutally large forearms. “Twenty-five fucking inches, boy!” he bragged, pumping his arms several times to emphasize his point. “The product of years of training, rest, food, and enough juice to turn a squad of runts into a platoon of studs!”
Neil’s mind skipped a beat. Twenty-five inches? Hadn’t it only been twenty-three, after the encounter with Clarissa? And twenty-two, before that? And what was all this talk about “boy” instead of Brock’s usual staple, “bro?”
Neil’s ponderings were interrupted as Brock continued his monologue. “A man with as much testosterone running through his body is always horny, boy. I get hard at the drop of a hat. Fuck, I’m horny every time I’m in the gym; watching myself in the mirrors as I lift, knowing that every rep is growing me into a bigger, better, stronger, sexier fucker of a man!” He lowered his arms slowly, still staring down at Parker, his broad back blocking Neil’s view of the gymnast. “I need to blow off steam afterwards,” Brock growled, reaching out to run his thumb along Parker’s jaw, “I think you’ll do nicely for that purpose, boy…”
Parker trembled with nervousness. Yet as he stared up at Brock’s overwhelming presence, he could only nod in agreement. “Yes, sir,” he said softly.
“Good boy,” Brock purred, running his thumb over Parker’s lips and then slowly pushing it into the gymnast’s mouth. Parker began to slowly suck on it. “Very good,” Brock smiled.
