No Hard Feelings

"What? Want me to do more to you?" Max laughed and stared at the comically huge nuts his brother sported now, which looked especially ridiculous in contrast to the femboy rest of him.
"N-no!" he returned in panic. "I just... thought you would be furious that I changed you or something."
"Well I was a bit at first..." Max admitted "But you made me cum for like... how long was that? Half an hour?"
"More like 10 minutes." Kevin corrected him and stared at that still throbbing pole of flesh in front of him that had spewed so much cum during that time.
"Yeah... definitely felt longer." Max grinned "Anyways, my point is ... you made my dick bigger, but joke is on you, I am into that stuff." he continued with a naughty grin. "And while those 10 minutes were kinda rude they were also... exciting. So you didn't really do much."
Kevin mustered the hunk of a brother he had now, his defined arms and abs, that even more handsome face on top - not to mention his new-found love for humping femboy guys - and gulped.
"Yeah... t-that's about it." An awkward silence formed between them.

"So... uh... what do these do?" Kevin eventually broke it and pointed at his way oversized balls.
Max just grinned though and just oracled: "You'll see soon enough."
"They do look kinda out of place..." Kevin tried to hint at the fact that he would probably not be able to fit into any pants with those.
Max stared at his brother's imbalanced proportions, run his hand up and down his shaft for a moment, before he offered with a grin: "Want me to make that dick bigger?"
"I uh... I guess?" Kevin wasn't sure if that was a trap, but if his 5 inches would get an upgrade he wouldn't say no. Suddenly he felt a tingle, and watched how within two seconds his dick doubled in size. While still being way out of proportion to his balls, those now 10 inches at least made him feel better.
"Um... thanks?" he looked back at his brother, still awaiting the wrath of god any second, however he just grinned.
"Don't mention it, I like to make things bigger." Max laughed.
"I think you eh... also made my cock stay hard?" Kevin realized, as that thing simply wouldn't budge from it's extremely erect state. This time though Max just stared at him like he just spoke Chinese.

"What do you mean?" Max raised an eyebrow.
"Like... you made me stay hard I think?" it felt strange to explain all that "Like you did make yourself stay hard earlier."
"I am not sure what you mean." Max' genuine confusion was very visible. "What else would a cock be?"
Suddenly it clicked in Kevin's mind. "Nonono!" he gestured wildly "I made you believe that's how cocks are, that's not how they are usually!" Max however didn't seem convinced.
"Dude, if you try to talk me into something at least make it somewhat believable." Max shook his head in disgust "I don't know what fantasies you have, but I won't turn your dick into some jelly wiggly thing like some of those freaks online show off."
"No wait! I made you like this!" Kevin tried to reason with him "I made it so that you would ignore any evidence... no matter..." He face-palmed when he realized his mistake. "Fuck!"
Max grinned as he left the room with his mighty rod on full display. "Sure, sure... Enjoy the presents, and have fun when you cum next time." The evil snickering that followed sent a shiver down his spine. Kevin had the bad feeling that these balls would contain not only lots of juice, but also a nasty surprise on top. And unless he could somehow convince his brother to give him that ring back, he was also probably cursed with a boner for life. Because that's the only way Max could now imagine dicks to be thanks to his little joke, which somehow turned into a hard backfire.
