The Grand Relief

Max' thoughts slowly came back from his 30 second orgasm he had blessed himself with. Deep inside he knew there was something important he needed to ask his brother. Something about this whole situation felt wrong, but his mind just somehow didn't want to focus on it for long enough so he could grasp it actually. Suddenly a hand around his cock ripped him back to reality.
"Damn... you're still hard?!" Kevin asked both confused and in awe of what his brother sported for him.
"Yeah... I think I kinda gave myself a perma-boner." Max explained, even though the reason kept slipping off his mind, until Kevin innocently asked.
"Oh... what happened?" Suddenly it was all back. The ring, the accident.

"Oh fuck... Kevin!" Max was wide awake "I accidentally gave it to myself with the ring!"
"Y-you... know about the ring?" Kevin suddenly stuttered.
"Yes... I... accidentally gave it away imagining it on someone else." Max explained, but he already saw in his brother's eyes that he would get it back anytime soon. "Kevin you need to fix this. I can't run around with a boner all the time!" But the smirk that came from his brother instead caused his back hair to raise.
"I like it though.." he let his hand run over that throbbing shaft and added with a sultry voice "If anything it should be even harder..." Max suddenly breathed sharply as it felt like he was getting an erection on top of his erection. He felt blood rush into his already hard cock, and turn it into the boner of his life. Seconds later his dick was at the very physical limit it could hold without bursting, leaving Max moaning in a mix of almost painful pleasure. He tried to speak, but the intense arousal blinded all his senses momentarily.

"Fuck, this is hot!" Kevin run his hand up and down that bar of diamond, sending Max into a series of twitches and even louder moans. "I guess you also made it bigger?"
"Ye-ss" Max squeezed out between his moans.
"Looks so hot... could be even bigger if you..." he suddenly stopped as he watched Max' cock suddenly expand even further, till it reached all the way from his crotch to his chin. "Oh fuck... I can just do that, can I?" Max failed to answer though, as the now arm-sized dick stuck at maximum erection drained every last thought out of his head.
"This is so fucking hot, bro!" Kevin went on top of his muscular brother and savored every inch of that gigantic slab of meat he had wished upon him. "What other sexy stuff did you do?"
"O-orgas..m.." Max stammered.
"You made yourself cum?" Kevin raised an eyebrow.
"No... lassSSt... l-long... lon..." Max felt his head spiral into a delirium.
"Ooooooh...." Kevin puzzled it together "So that's why you came for like a minute? Gosh that was hot af!" He begun kissing and licking that fun-rod his older brother now sported. "Must be so hot watching you cum like that even longer... imagine you had like 10 minute orgasms..." Kevin was clearly lost in a fantasy, but it was too late. Max felt it build, and when the first jet left his massively enlarged member, he knew he was doomed.

Max heard himself scream in pleasure, as his soul got washed away into a heaven of pleasure. His entire body started to twitch and pump hot juice out of his cock from a seemingly endless supply in his balls. Max had many orgasms in his life, but this one was different. It wasn't made to get the spunk out, it was made to cum, over and over again. The climax had started strong already, but kept climbing further and further, overloading every cell in his body with intense orgasmic pleasure. The last ties to reality slipped from his mind, and he felt nothing else anymore, but him cuming, pumping, twitching, screaming. Like a vinyl stuck on repeat, he launched shot after shot after shot, with no end in sight, or even fathomable at the distant horizon. He felt his cum form a puddle on his well-trained chest, but there was nothing he could do anymore to stop this. He was locked in Kevin's fantasy now, a fantasy of that hot, older brother, endlessly cuming with a gigantic cock.
