Treacherous Trickery

There was a devious joy in watching his older brother helplessly stuck in a cum-loop of his own making. Not that he did have particular thoughts about having sex with his brother before, but when he saw him with his enhanced package throbbing, Kevin couldn't help but to get turned on by the sight. And as the ring that magically appeared on his finger granted the power to have his literal imagination become reality, it kinda happened. He just briefly pondered how his brother would look like with it reaching all the way up to his face, and a moment later he no longer needed imagination as it had become reality. From there to sucking that cock, how he would look like if he came, seeing him cum, and then wanting nothing more but for him to keep cuming for now... And well there he was: sunk to the floor with his giant dick, eyes rolled back, and jet after jet eruption from that impossibly huge monster of a dick.

"Thanks for making it stay hard all on it's own, by the way..." Kevin laughed and leaned down and laid his hand on that shaft just to feel it pulsing and throbbing with every blast. Then an idea hit him: "Do you know what would be fun?" Of course Max was no longer in a state where he could answer. "If you wouldn't even remember it being anything else but that. Like it had always been super erect all the time." His thoughts drifted to his brother walking around with his cock obscenely bouncing around, and he was not only helpless to change it, but didn't even know what had changed. His other hand inevitably went to his own erection. "Like even if someone presented the most compelling evidence, and you would still believe being hard is the only thing a cock could possibly be." He felt himself getting closer also. The idea of his brother furiously explaining how dicks just had to be hard, like it was physically impossible for them to be anything but that, was so hot and humiliating at the same time. Everyone would think of him as the insane perv, and at home he could enjoy him fumbling around with that ridiculous boner. Kevin was just about considering if he should go over the edge as well, when Max' 12 minute orgasm was suddenly finally over.

"P-p...l..." his voice was faint and broken.
"You had fun?" Kevin laughed.
"P-please... undo... that..." Max stammered. Kevin had difficulties even understanding what he was uttering under his still fast breathing, when suddenly Max got reinvigorated with a rush of stamina.
"Wow..." he blinked for a moment. "Shit bro you need to return my orgasms back to normal. I can't just keep cuming like that every time I do!" A look at the exhausted, sweating face of his brother kinda reminded Kevin that his brother was human after all. It was fun watching him flopping around like that, but he got a point.
"Uhhh... how do I imagine normal orgasm times?" he wondered, and Max rolled his eyes.
"Of course... Mr. no imagination is at the steering wheel." Max groaned, making Kevin slightly angry "I certainly would know how to do that."
"Oh yeah?!" Kevin didn't want to grant him that success after he had so successfully humiliated him like that. Quickly he tried to figure out what exactly his brother would do if he had the ring, like: what would he say? Would he like wave the ring around somehow? Or just...

"Oh you are are such an idiot!" Max suddenly interrupted his trail of though with a cackle. It took Kevin a moment till he saw the ring on his brother's hand again, exactly at the place he had imagined it just a moment ago.
"Fuck..." he cursed himself. Tricked by the oldest trick in the book, if there was one about magic Gonzo rings. Max pondered him with a devilish smile while he got back up from the floor, which was only made slightly less intimidating when his gigantic dick poked into his face several times. For some reason though despite the panic Kevin felt his dick turn rock-solid.
"C-can we talk about this?" he pleaded.
"No." was the short answer from his brother. A second later he felt his balls expand rapidly, till he sported a pair rivaling the size of coconuts. He waited for a moment, but nothing else seemed to happen.
"That's... all?" he wondered, as he looked back up at Max' satisfied expression.
