A 30 minute speed com for Bobert Bobert who wanted some Donkey Kong gym and muscle growth action.

Has a big gorilla working out and having a bigger orgasm while growing, all sorts of stuff tiny otters like.


Donkey Kong gruffed out. His arms were straining and tense as he tightly gripped the metal bar holding up several hundred pounds of weight on either end. His eyes were shut, his teeth were clenched, and he was sweating hard under the exertion of trying to lift the weights. It was practically dripping from his body, soaked into his brown fur and hair, and his heavy chest huffed and pumped while his breathing was strained but steady in working to lift.

Another deep grunt escaped from his lips, his whole form tensing up as the bar was lifted slowly. Inch by inch it was being raised, and DK was starting to huff as it was gradually moving past his center of gravity. His furry chest was bristeling and his gym shorts were getting tighter. As the blood flowed through his body, helping to pump his muscles to get past this wall, his junk was grazing along his hairy legs and thigh within his shorts. While he was lifting, each movement was making the coconut sized nuts jostle and slosh, while his thick meat kept slapping in its trapped, tight, confinement.

DK was trying his damndest to not pay attention to his expanding dong and focus more on his lift, but it was starting to become a losing battle. He retightened his grip on the bar, the side of his thick arms brushing along his pecs as they pumped forward, and felt the cold feel of the metal brushing along his exposed nipples. The sudden sensation of cold meeting hot sent a surge through his body, and his cock took the brunt of it, suddenly pushing forward and bulging up his tight gym shorts even more

The ape took a few more deep breaths, shut his eyes, and still kept working to lift the weights. His sweat was making puddles at his feet, and soon his dick was staining the fabric of the shorts, pre oozing out like a faucet. He kept his eyes clamped shut as the bar further lifted, getting over the peak of his pecs, until he finally got the bar right under his large chin.

A grin escaped from DK's lips at the feeling, and a surge of testosterone was rushing through him. In a single motion, he finally pushed the bar up even further, his grip tight on it, and then raising it high over his head. As he was doing that, his thick shaft began to fire, unloading the hot cream inside of his hairy, fuzzy, balls. The first shot completely stained out the front of them, making a dark wet smear across them, while the excess began to drip and ooze down his legs and thighs, mixing with the sweat that was coming off of him and pooling to the ground.

His moment of triumph was met with a powerful orgasm, with Donkey Kong holding that position, moaning in exhausted pleasure as endorphins and testosterone continued surging through him. His gym shorts were completely soaked, now more by cum then sweat, and were getting so soaked that the fabric was starting to dissolve.

DK kept grunting, and his pants soon fell off of his body, letting the rest of his blast shoot across the weight bench. Streaks of thick white ropes painted across the equipment and while still breathing heavily, the hairy primate slammed the bar back down. He was taking longer than normal to catch his breath, his heavy breathing further making those large pecs of his pump outward and upward. The hairs bristled along his fur with each pump, and he arched his back as the orgasm began to die down.

Even though his orgasm was ending, his erection wasn't dropping. His breathing was still hard, and then he felt more of his body shake and rumble. He started to clench his hands into a fist, and then, below his wrist, his muscles began expanding outward rapidly. His already large forearms were growing larger and larger, the muscles filing with the excess hormones he had been secreting. Within moments, it had moved down to his biceps as well. The monkey muscles stretched outward, audibly groaning while more growth surged through the sweaty, hairy male.

His pounding pecs strained and pushed forward as well. The hairy mounds were rubbing along his thick and growing arms. Muscle met muscle and hair met fur as DK moaned out, raising his head up and grabbing at his beefy chest with his growing arms. His neck began to thicken as well, the tight muscle cords there expanding to support the new, growing chest and sudden expanding back that DK was getting.

It continued to surge through his form, moving down along his body. His muscular front tightened and grew even hairier. The thick fur adoring it became a pelt, and thicker hair moved all the way from between his massive pecs all the way down to his groin. His large thighs began to grow outward as well, and DK's large legs were growing rapidly, aiming to support all the new muscle weight that he was getting.

Even while the rest of his body was growing larger, it wasn't stopping where it had started. His arms and chest were still getting bigger and bigger. His broad, meaty paws rubbed along his chest. The palms of them slid across his growing nipples as well, each the size of a dinner plate, and continuing to drip and soak with his sweat. He could feel more dripping from the back of his head, going all the way down to his tight ass, as his glutes grew as well.

The largest surge of growth then came for his arousal. While no means small before, his huge hairy nuts soon began to drag down with the excess manly goo brewing inside of them. Each sphere bulged outward and more fur grew on the surface, as they moved to the size of coconuts to the size of truck tires and began to slosh below his knees. His cock, pushing three feet before this had started, was getting thicker and longer. Veins popped along the surface of his meat, further fueling the intense growth as the source of his hormones continued to flood his body.

The thick glans and head of his cock brushed along the hairy front of the simian, and foot after foot of cock pushed out from his groin. He started panting hard, still fondling his huge chest and nipples and brushing his palms through his fur while his cock began to push up between his pecs. He started flexing them, grinding his muscles along his towering shaft while it pushed up deeper into his chest. He could feel it starting to ooze pre again, soaking into his hair in the musky crevice of his pecs.

Soon, it pushed through and crested to the top, his massive dick now staring at him right in the face. His chest was practically flexing on its own now, and his second orgasm was rumbling deep within him. The first shot was the most powerful cumshot DK had ever felt in his life, easily matching and surpassing every other orgasm he had ever had before combined. It splattered square in his face, soaking his furry features and filling his nose with his own musk, which only further aroused him.

Needless to say, the second shot was even stronger because of it. Gallons of cum erupted out of his dick, bulging his urethra, and even had enough force to spread his pecs as it flowed upward. DK opened wide, taking a big blast of it into his own mouth, and let the rest freely fire out. Cum and seed splattered all over the gym, and most of it onto his fur. He just reached and rubbed it in, soaking his body in his own spunk and panting lustfully. His tongue was hanging out, brushing his thick fur and hair in his palms while he rubbed along his huge body.

The next shots were even more powerful and potent, each one making DK's entire muscular body shake. He was roaring now, grabbing his own cock and stroking the blasting member to get every drop of cum ejected out of his nuts, now inches away from smashing into the ground. Pump after pump of seed flew everywhere, and each movement made DK's furry body grind along itself until he felt the last drop gush out.

Gallons of cum were splattered everywhere and ropes as thick as a meter were draped over every surface. He had easily cummed his old weight in seed, and his thick member, slightly more sensitive, but still twitching, slowly slipped out from between his furry pecs. DK took a moment to catch his breath and then admire himself in the cum-soaked mirrors along the wall. He grinned and lifted a single arm to flex it, the bicep bulging upward so far it went past his own head.

He wasn't done yet though, and looked back at the cum-soaked weight he had been struggling with just minutes before. Without a word, he tripled the weight on it, and was ready to go again.
