A total upset!

The next stage was slow-going. Most Alphas had pills or mods that gave them permanent erections, so fluffing was something of a lost art. However, it was probably the first time either cock had been touched by another person, so they responded quickly to the sub-par treatment.

Both brothers closed their eyes, probably trying to forget who was giving them their very first handjob, but Jason made them look.

"Stare at your brothers' cock," he ordered. "Watch your competition closely."

The older brother was the first to grow. His dick started big enough that his mother could get a full hand around it, after all. It swelled quickly to full mast, stopping at a perfectly average five-and-a-half inches. Mom tried to speed up, thinking he needed more stimulation, but he reached down and stopped her suddenly, hips bucking as if he were close to orgasm already.

The younger brother watched with widening eyes as his brother grew, but the nervousness was quickly replaced with surprise when it was clear that he'd reached his limit.

His own cock grew more slowly, as Mom could only get a couple fingers on it at once. She also seemed a little distracted by his bigger brother, but when he stopped her she was able to focus more on junior. It wasn't long before she needed a third finger, and then a fourth, and finally wrapped her whole hand around his shaft and could stroke him properly. While his brother still won out in girth, he quickly caught up to and even overtook him on length. The "little" brother was nearly seven inches when his grower finally stopped growing.

"Well, mom?" Jason prompted. "Who's in charge?"

The mother's attention was focused entirely on the surprise monster in her left hand. Her right wasn't moving anymore and had nearly fallen off her older son's cock, but she was carefully and attentively massaging her younger son like the slut she'd been trained to be.

"Tim," she moaned at last, bringing letting go of the smaller cock complete to wrap both hands around the bigger one. "He's way bigger than Eddy! He's even bigger than his father was..."

Jason laughed at the sudden display of lust and at the furious disappointment on Eddy's face. He rose and handed the basketball to Tim, who took a moment to snap out of his distracted pleasure.

"The ball is yours, kid," he declared, "and so are these bitches."

He slapped Eddy's ass and added, "Both of them."

"B-both?" Eddy gulped in surprise, tearing his eyes away from his brother's cock. "But I'm not... Tim's not... Are you?"
