Preston Silverfang ran a paw through his yellow hair. The Lucario had been hard at work for days now trying to perfect his new plant growth serum. If he could succeed on this it would mean the end to world hunger for all Pokémon. Even desert areas would be able to grow plenty of food with ease. He would win awards for his work and finally be able to get the funding he needed to get a proper lab. Not this hodgepodge of a lab he had built over the years. His lights were solar lights because he couldn’t afford to have both regular lights and solar lights installed. So, Preston installed the solar lights himself.

He had used lab stools to sit on that always wobbled, the desks in his lab were all ancient old, heavy as lead desks no one wanted anymore, his beakers, flasks, test tubes, and vials had all seen better days. Most of what he got was from high schools tossing them out, many were stained with this and that. Most didn’t even have their measurements on the sides anymore. Wore away from years of use. That didn’t matter to Preston if Lucario's were anything. They were precise. He could eyeball most measurements to almost perfect accuracy. Preston had no love for fighting as most Lucario did, but still, he appreciated the evolutionary gifts his fighting heritage had given him.

As Preston poured in the last chemical needed for his serum, he placed the test tube into his frankinstined centrifuge. Setting it to a minute Preston sat back with a sigh “I hope this one works,” he said as he pulled out a syringe ready to pour the contents from the test tube into it. Once the centrifuge was finished Preston plucked out the test tube, uncorked it, and poured the serum into the syringe. Placing the needle down on the desk he rubbed his temples. This one had to work, he thought to himself. He had been pulling multiple all-nighters to get this done. The scientist was running on fumes.

Massaging the back of his neck with his paw, Preston groaned, he needed some stress relief. He needed a month's vacation, he needed a massage, he…. needed to bust a nut. It was the quickest and dirtiest way of some immediate stress relief. Glancing around to make sure he was alone, the pervy Lucario pulled out his modest cock and started to rub it with his paw. Groaning his cock swelled in his hand growing hard. He grunted as his paw slid up and down on his cock. The other paw was holding him up as he leaned near the desk. As he pulled his schlong in his lab, the desk he was leaning against shook from Preston’s stress relief session.

Closing his eyes to enjoy the pleasure. Preston never noticed that the needle he had filled with his latest plant growth serum was bouncing closer and closer to the edge of the desk. Just as the masturbation obsessed Lucario came the syringe fell from the desk and stuck into his hard cock. Preston’s moment of pleasure was replaced by a jolt of pain. Letting out a yelp, his paws quickly plucked the needle out of his dick's head: "Oh shit!” Preston said as he looked down at the now empty syringe.

“Oh crap, what have I done?” He said, looking past the syringe to his still hard cock. He could see the green goo coursing through his veins “what am I going to do?” He asked out loud, unsure of what to do next. Placing the needle back onto the desk Preston reached down trying to squeeze some of the serum out of his cock. Though to his dismay none of it came back out as he continued to stare at his cock, he could see it. Bit by bit his cock was growing or at least he thought it was. Reaching down he gripped his member, sure enough, he could feel it growing bigger and bigger in his hand “it worked!” Preston exclaimed “the growth serum works!” He shouted to the empty lab.

As the glow from the solar lights above Preston continued to shine down on him his cock continued to swell and swell bigger. What had once rested comfortably in his hand was now long enough to be double fisted. Watching his cock grow and grow in front of him only turned the shiny Lucario on. Preston already loved masturbating, “might as well not let a good opportunity go to waste," the perverted Pokémon said as he started to rub his expanding dick with both hands. “Ohhh Arceus this feels good! Way better than it felt before!” Preston growled as his cock and balls billowed out bigger and bigger as he rubbed it.

“Ohhh it just keeps growing and growing! It’s getting huge!” Preston exclaimed as he fell back onto his butt. His hands continued to work their magic, rubbing his swelling schlong all over. His balls were so large now they were pushing his legs apart his nuts were like beach balls now billowing out filled with cum. “I can’t believe the serum is so potent, unnngghh I can’t believe it’s working on me!” Preston said as his cock pulsed and grew bigger. “The UV lights keep making my cock grow and grow and grow!” The horny Lucario cried out as his swelling balls pushed out more and more.

Preston repositioned himself while he still could so that his rapidly growing balls wouldn’t force his legs apart anymore. Lucario were flexible creatures, but even they had their limits. As he continued to expand, and swell Preston’s eyes started to glow. This romp of sexual pleasure was activating his aura in the same way a fight would. Feeling the power building from within Preston used it to stimulate his cock more. Using his force palm, he sent waves of energy into his cock, making him gasp and moan in bliss as he grew closer and closer to orgasm.

The bigger he expanded the less space he had in his lab. The lights continued to force his cock to keep growing fatter and longer. The desk he had been next to was pushed away as his inflating cum factories filled and filled with more seamen. The yellow furred Lucario grunted as his knot started to swell out. He was getting so close now. “Ohhh come on I’m almost there I want to cum so badly!” He called out as his now car-sized nuts started to clench over and over. Letting out a roar of pleasure Preston’s ball pushed out with everything they were worth. He bellowed and howled as cum burst from the tip of his cock.

Wad after wad launched from his massive shed-sized cock. He continued to work his pleasure stick with his paws. He huffed and panted lustfully as his orgasm stretched on and on, much to his delight. He was covering his lab in his love juice, even as he came, which only seemed to be a catalyst for growth. Shuddering Preston watched as his swelling member lurched out growing much faster than before “Ohhhh fuck! It’s not stopping! Unnnghhh I don’t know if it will!” He closed his eyes and continued to rub his giant cock.

With a smash and a crash, his cock head battered through the roof of his lab. “Plants could be trimmed and kept in check, Preston’s cock was not a plant,” he gasped as the warm summer breeze blew across his cock. The heat of the actual sun baking down on Preston’s manhood only fueled more growth. Preston’s balls filled his lab in minutes. The pleasure drunk Lucario didn’t care that he was about to destroy his lab. He was too busy trying to squeeze every last ounce of pleasure out of his behemoth joystick.

“Ahhh yes! More! More! It’s growing out of control! I want it to be bigger! I want to cum harder!” Preston shouted his back at a wall now having been shoved into the back of his lab. The pressure from on his balls was so much now he couldn’t help but cum again his massive nuts being milked by his soon to be doomed lab. As Preston came once again his cock and balls surged outgrowing bigger and faster than before. Somehow the growth serum must have altered the way his adrenal glands affected his cock and balls. Every time he came it only made his cock and balls expand faster than before.

The bigger his cock and balls grew the more there was to bask in the sunlight. With a loud boom, Preston’s lab exploded out in all directions. The once squat Lucario let out a sigh of relief with the potential of being crushed by his own balls no longer on the table; the hypersexual canine-like Pokémon refocused on jerking his cock off as much as he could. Pulsing waves of aura flowed through his cock pushing his ecstasy to even greater heights. The four appendages on the back of Preston’s head started to vibrate and glow as more and more of his power was drawn out. These appendages often allowed Lucario to be more empathetic with others as they helped Lucario to sense emotion. They could also be used to help heighten states of emotion a Lucario was going through.

Preston used his abilities to push his arousal through the roof. The dog-like Pokémon only got hornier and hornier as he continued to grow out of control. His cock was so massive now it was taking up multiple city blocks. Still, it continued its rampant growth. The massive cock pushed out bigger and bigger and bigger. Buildings looked small compared to it, cars were little specks. “Ahhhh more! Bigger! Fatter! I never want to stop getting hornier!” Preston demanded as his cock smashed through buildings all over the city. City block after city block was demolished by Preston’s unstoppable penis.

It wasn’t long before the hyper-endowed pleasure obsessed Lucario was starting to overtake the region. Joto was quickly nestled between a pair of black and yellow fur covered balls. Cum splashed down into the ocean as Preston’s cock started to stretch across the planet. The perpetually hornier Lucario gasped as his balls sunk into the ocean all around him. “Cold!” He shouted before laughing, realizing how massive he had become. His cock was so massive now that even if he himself wasn’t in the daylight at least some part of his still growing like a weed cock was.

Preston could feel the planet getting smaller and smaller as his nuts started to wrap around it. The planet was quickly nestled between Preston’s balls as his cock and balls pushed out bigger and bigger. With no more atmosphere blocking the UV rays Preston’s cock and balls shot out growing much faster than before. Preston’s balls made the earth look tiny, his cock grew fatter and longer than each of the planets in the solar system. Before growing long enough to overtake the solar system itself.

Adding light-years of girth and length to his cock with each passing second Preston was only lost to the pleasure. The bigger he grew the more starlight hit his cock and balls making them expand faster and faster and faster. Solar systems looked tiny compared to his soon galaxy-sized cock and balls. There was nothing to slow down Preston’s growth; the horny cumming Lucario only howled for more each time he came. The distance between orgasms grew shorter and shorter until Preston was lost in a state of unending orgasm. Cum just constantly spewed from the tip of his universal cock. Even then it wasn’t enough Preston wanted more. He would keep growing as long as there were stars to feed his cock.

The End.
