Neil pulled down his tight boxers, letting his cock and balls bounce free. He kicked the undergarment aside, adjusted his stance, and began to stroke his hardening member, reaching around its girthy ten inches of length, double-fisting it with both strong hands. A distant part of him marveled at how easy it was for him to strip down in front of Brock and start jacking off. Of course, he’d done much more with the mature-looking hulk; he was trying to avoid a repeat of that, at least for the moment. What if Brock got too old? Although the big man himself seemed oblivious to his dramatic aging, Neil was beginning to worry. The way things were going, Brock would be in his 70’s soon. And then his 80’s. What then? What if he just dropped dead of old age at some point?
Neil’s stroking slowed for a moment as he pondered the Brock problem. The implications worried him. His hands stilled, gripping the root of his meaty shaft. But his mind’s wanderings were ended by the big man’s voice. “Fuck that looks nice,” Brock growled, staring hungrily at Neil’s erect member. The mountain of muscle grinned, his gaze moving down and then up, taking in the rest of Neil’s muscular body. “If you need some help…” Brock’s grin widened further.
“Nah,” came Neil’s drawled reply, as he grinned back and began to stroke again. Brock wasn’t dead yet. And he didn’t want to push the man any closer to it with another sexual exchange. He’d have to play this carefully. And right then, he needed to get off, before Brock decided to ‘help’ him. “C’mon, Brock,” Neil teased, “Aren’t you going to get your rocks off too?”
“Yeah…” Brock responded. He pulled down his compression shorts, exposing his monstrous thighs. As he straightened again the quadriceps popped into full view as he flexed them. His huge legs pushed forward his fat, short cock and empty ballsack, but his member remained soft. Nonetheless, he put on a cocky grin. “Been pumping this bad boy up…” he growled, “He gets a lot bigger when he’s nice and hard… not as big as your monster, though…” He waggled his eyebrows suggestively, staring at the huge dick that Neil was pumping.
Neil had to redirect Brock’s attention away from his larger cock. “Yeah, how big are you these days?” he asked, trying to sound eager, “Show me, Brock, I want to see that dick you’ve been pumping!”
The big man laughed and reached down to palm his flaccid dick. “Six and a half, fully hard,” Brock replied proudly, “Getting close to seven though, I can tell. I’ve been stretching out this bad boy as much as I can, taking these weird-ass herbs. Too bad I can’t just lift with my dick the way I do the rest of me!” He laughed louder at that and stroked his cock further, trying to coax it to life. But despite the potent cocktail of artificially administered hormones that suffused his system, his physical age was making it difficult to achieve an erection.
A flash of annoyance passed across Brock’s handsome-mature face. He didn’t know why his dick wasn’t cooperating. Usually it went up without much coaxing! Any time a nice set of tits or hot ass walked by, he was usually sporting wood within seconds! Fuck, he was Brock Medina! He was the biggest, strongest stud on campus! He was a fucking sex-god!
Brock’s huge arms rose and he flexed them proudly. “Twenty-five inches, bro,” he boasted, displaying himself to Neil. He held the pose as he twisted his mighty torso to catch part of his reflection in a nearby mirror, loving the sight of even a single part of his huge body, as the mirror was too small to contain all of him, even at a modest distance. He pumped his arms several times, making his bloated biceps dance. Neil sucked in his breath, beating his own big dick harder as he watched Brock flex and preen.
Brock’s arms came down and he stepped into a ‘most muscular’ pose, one leg forward, both arms brought down, flexed hard, framing his striated pecs and deep-cut abs. “Aww fuck bro… love this pose…” the hulking man growled, “Gets me horny every time!”
It certainly had an effect on Neil. Watching Brock pose and flex brought him to a fountaining climax, his big dick spurting an arc of cum through the air. It splattered on a nearby bench as Neil groaned loudly, gripping the root of his spasming rod as it continued to spurt out more cream.
Brock groaned as well, watching Neil’s performance with admiration and a healthy amount of jealousy. While he certainly didn’t begrudge the smaller man his magnificent cock—which managed to look big even on Neil’s muscular body—it only reminded Brock how small his own looked, even when fully hard. The bigger the rest of his body got, the smaller his dick looked in comparison. Pumping had helped a bit, but it was not enough!
Brock reached down to stroke himself. There was a tingle running through his soft shaft, a faint itch. The first sign of arousal. But it was faint. Much too faint. It was frustrating as fuck.
The hulking bodybuilder watched as Neil grabbed a towel and wiped off his cock with it, then proceeded to clean off the bench that he’d just anointed with cum. Even after his spectacular orgasm, Neil was still mostly hard. “Fuck that was a great show!” Brock offered enthusiastically, grinning wolfishly at Neil who blushed back. “I bet if you were to fuck me, I’d wind up shooting a load like that too!” Brock turned to display his mighty glutes and slapped one in what he imagined was an enticing invitation.
Neil froze for a moment. Then he finished wiping up the bench and tossed the towel aside. He had to think of something quickly! He was desperately trying not to fuck Brock in any way, but the big man’s lust was unmistakable.
“I have a better idea,” Neil said, his mind racing, trying to come up with just such a thing. “How about if you and I start working out?” Seeing the dubious look on Brock’s face, he quickly added, “Seeing you flex sent me over the edge, big guy! So how about it? You and me, naked, working out together?”
Brock tilted his head for a moment, then smiled. “That does sound hot…” he offered, smiling smugly before strutting over to the impressive rack of dumbbells. He picked the largest pair, 100s, and began to perform dumbbell squats, his mighty rear going up and down, powered by his huge legs. “Going to need to get some bigger weights, bro, I can barely feel these!” he boasted, clearly not challenged by the two hundred pounds he had picked up. “You gonna get over here and train or are you gonna stare at my ass all day? If that’s the case, there’s something more interesting you can do with it…” Brock grinned impishly and paused the exercise to flex and bounce his glutes several times.
Knowing he had to get Brock’s mind off of being fucked, Neil stepped forward and gave each cheek an admiring squeeze. “I know it’s a light day, but you’ve got to challenge yourself a bit more than that, big guy,” Neil chided, “Maybe some incline press would be more your speed with that weight?” He stepped away and adjusted a flat bench to be in the incline position.
“Fuck you!” Brock shot back, but the response was good-natured, despite the profanity. The hulking man ambled over to the bench and planted his tremendous mass on it. “Admit it,” Brock grumbled playfully, “you just want to perv out on my big old muscle tits!”
“These jugs?” Neil asked in reply, sounding just as playful, standing behind Brock and reaching over the big man’s traps and shoulders, groping the thick slabs of beef. “You think your chest is bigger than Clarissa’s rack yet?”
Brock laughed and began raising the weights, his pecs moving and swelling as he performed the exercise. “Once I get a pump going, definitely!” he growled back, finishing twenty reps and resting the dumbbells on his knees.
Neil took the opportunity to explore Brock’s thick chest, running his hands over the twin expanses of muscle, caressing them admiringly. As he looked over one of Brock’s powerful shoulders, he noted with satisfaction that the big man’s cock seemed to be stirring just a bit. “You about ready for your next set?” he asked, giving Brock’s pecs a hearty squeeze, groping the slabs of beef.
“Fuck yeah!” Brock growled in response, easily getting the hundred-pound dumbbells into place overhead. As he pushed them upward, Neil walked around to stand at Brock’s side, then knelt beside the hulking man. “What’re you…” Brock began.
“Just lift,” Neil said simply. Not really understanding, Brock complied, pushing both dumbbells upwards. Neil leaned forward, one hand gripping the back of the bench for support as he moved in and gave one of Brock’s nipples a deep kiss. His other hand ran along one of the hulking muscleman’s giant thighs, starting on the outside and moving toward the knee, then circling over and around, then returning by passing over the sensitive flesh of Brock’s inner leg. Upon reaching the big man’s crotch, Neil’s curious fingers toyed briefly with Brock’s shrunken sack before exploring the mostly soft sausage that rested above.
“F-fuck…” Brock gasped, a shudder running through him as multiple sensitive spots were triggered at once.
“Keep lifting,” Neil purred, rolling his tongue around Brock’s areola before lapping at the nub that jutted out from it.
The big man eagerly complied. Neil was locked onto his target—one of Brock’s nipples—and followed it everywhere as it moved during the exercise movement, kissing it, licking it, sucking on it. The hulking bodybuilder groaned in approval and Neil could feel the big man’s cock begin to harden as he teased it with his free hand. Slowly, it rose to its full size, just a bit over six inches long and quite thick. Neil gave it a few expert tugs, then stood and took up a new position in the space between Brock’s mighty legs. He kissed and nibbled at the big man’s inner thighs and was rewarded by a series of energetic grunts from above. Looking up, Neil saw that Brock was still lifting, his pace a bit faster, rep after rep seemingly without tiring.
“That’s it, big guy, your pump is going to be insane!” Neil said encouragingly as he gripped Brock’s erect dick between his powerful gymrat hands and began to stroke. The huge bodybuilder let out a low groan of pleasure, his movements hesitating for a fraction of a second before he resumed lifting. Neil watched with great interest, matching the tempo of his strokes to that of Brock’s lifts. After a moment the big man caught on; he began to lift faster, the hundred-pound dumbbells flying up and down as Neil kept pace, stroking Brock’s dick with increasing speed, the shaft hard as could be and throbbing eagerly.
The weights dropped from Brock’s hands to the padded floor below, bouncing off harmlessly and rolling to the sides. The hulking bodybuilder breathed in heavily, his chest rising and falling, each pec dramatically pumped up. A moment later he erupted, his cock sending a jet of cum a foot or so into the air as he let out a series of magnificent roars of orgasm.
Neil continued for a moment longer, then pulled away, his hands sticky from the other man’s seed. He stood, and was amazed by the dark red color of Brock’s pecs, as well as their dramatic appearance from what appeared to be the biggest pump of all time.
“All right,” Neil grinned, looking down at Brock with amusement, “are you finally ready to get a proper, off-day light workout in?”
“Fuck you…” Brock wheezed, his mighty chest rising and falling. But his words had no heat in them. “After that… I gotta catch my breath, bro…” he managed.
Neil grinned and nodded, taking a moment to really look Brock over. What he saw pleased him; despite the fantastic chest pump Brock was enjoying the rest of the big man had remained as-is; he had neither grown five years older nor added another inch to his arms, as best as Neil could tell. The Brock he was looking at was the same as the one who had greeted him at the door, but totally naked, sporting an amazing chest pump, and splattered with his own cum.
Apparently, Neil surmised, more than just a handjob was required to trigger a change. That was good to know. Important too; he had noticed that his own libido had been skyrocketing in the last few days, and based on his encounters with Brock, Matt, and Lucas, he was hardly alone. Perhaps some form of penetration was required to activate a change? Or could it be something in his semen? Maybe…
“Earth to Neil, bro,” came Brock’s rough voice. Neil’s head whipped toward him. The big man was standing, recovered from his recent orgasm. “We gonna get that light workout in or what?” Brock asked, a grin across his face, “Now that we’re both taken care of, that is.”
