12 DAYS OF GROWTHMAS – December 19th (Patreon)

Already, it was a miracle that Max was still allowed in public now that his cock had started oozing a steady stream of attention-seeking precum. But things got even weirder on the morning of the nineteenth.

He was walking by the restaurant he’d enjoyed so much two days before when he noticed the flirtatious waiter. Max couldn’t believe his eyes. The dude was jacked as fuck!

The 7’2” giant stormed into the empty restaurant and walked up to the bar.

“What the fuck happened? The last time I saw you, you were a 300-pound cum-blob!”

“Hey, man. Nice to see you again so soon! I don’t know what to tell you; this is how I woke up today. The fat was gone and I looked like this instead.”

The waiter was radiant with joy. He wasn’t the pear-shaped behemoth Max had left behind; now he was 280 pounds of pure, lean muscle. The uniform he was wearing looked ridiculous on him—it was at least three sizes too small and the seams on his biceps had already burst open, the buttons audibly begging for mercy every time he inhaled.

“Looks like your cum can give you a lot more than just a huge gut, sweetie. Thanks, babe, I love the new me. I’m free tonight, if you wanna see what another round can do.”

Max barely heard him. The wheels in his head were turning—he had to get to the gym!

He still got the waiter’s number first.

In the last 48 hours, no one had gotten as much of his cum as his friend Jonas. More than anyone else, his gym buddy couldn’t get enough of his dick.

When Jonas had come by his house last night, he had already been 420 pounds, with a belly that reached legendary proportions, but he wanted even more. He would have endured anything, as long as Max kept filling him with his sweet juice. When he left, he’d been 490 pounds, with the promise of more to come. Seeing him waddle away, a walking cum barrel, was enough to fill Max’s balls right up again.

Max practically ran all the way to the gym.

When he reached the doors, a little crowd had formed to wait for him. A wild din of voices flooded the gym lobby.

“Make me bigger too!”

“Grow me, grow me!”

“You can fill me as many times as you want!”

But leaning against the counter, looming behind them all, was Jonas, and Max didn’t have eyes for anyone else.

He looked magnificent. He wasn’t the 500-pound blob Max had created the night before. Instead, he had transformed into a massive, 410-pound off-season muscle mountain. His grin reached from ear to ear when he saw the hard bulge growing down Max’s thigh.

All Jonas was wearing was a snug pair of underwear. Nothing else fit him anymore. Still 5 foot 8 inches in height, he was now as wide as he was tall, unbelievably dense with muscle mass.

It turned out that Max’s upgraded libido was more than a match for Jonas, and plenty of others. Within 24 hours, everyone in the gym was jacked beyond description.

Max’s balls hadn’t been this empty in days! By the time he came for the fiftieth time, they were down to the size of coconuts, minuscule by his standards. But after he helped himself to a gallon of water, he noticed they were starting to swell again.

“Nothing makes me cum harder than making you guys bigger,” he said to the crowd gathered around him. They cheered. Even after a full day, Max still outsized everyone in the gym by several inches. He was the Santa Claus of muscle mass, and the supply of gifts was endless.

Jonas, having surpassed 500 pounds of muscle, had finally stopped getting bigger. He was a wall, unable to move like a regular human being anymore. When someone offered him an oversized shirt, he learned that he wasn’t able to reach his own head anymore. His pecs got in the way of his arms. His back had become too wide for him to reach up. His traps and neck were also a big problem.

“Come on. Make me bigger. One last time.”

“You didn’t grow the last three times I fucked you, Jonas,” Max said happily. Seeing Jonas this big made him only want one thing: to grow his muscles even bigger. But it seemed that Jonas’s body had no more room to grow, which was probably lucky for him. “But if you insist, I’m happy to blow another load. Hell, my balls are full again already.”

And even though Max’s aching cock felt like a truck had run over it—twice—he was immediately hard again, ready to slip into Jonas’ huge donut hole.

“Fuck, the bigger you get, the better it feels, Jonas!”

“Mhhh, yessss…I was just thinking the same. Holy fuck! You have the most incredible cock!”

When Max came this time, Jonas hyper muscle gut was the only thing that swelled. Dark red stretch marks covered the sides of his strained abdomen. His head was slowly disappearing between the valleys of his shoulders, pecs, and traps as the incredible orgasm rolled through his system. He rubbed his huge, overfilled roid gut.

“So full, fuck! That was so intense, man! If you don’t stop inflating me, I’m gonna pop one day. Jeez!”

Max looked around at the assembled mass of jacked, built guys who had gathered to watch. He realized he was now entirely surrounded by fellow muscleheads. His own army of professional bodybuilders.

“You know what, guys? I think this is gonna be the most amazing Christmas ever.”
