"Who the hell is this?" Ike asked the room. Luke's pale Japanese face turned bright red when he saw Ike, the 8 foot tall, naked, muscular, middle eastern man. Luke was dressed much more modest, now that he had grown into an adult he had to borrow Kyle's clothes from home. He was dressed in brown leather shoes and a matching belt around blue slacks, with a white button up shirt tucked in. His black hair was styled into a smart comb over.
Kyle invited Luke in and clasped his hand around Luke's shoulder, "Trevor, Ike, this is my son Luke"
"Your son?" Ike asked skeptically "Dude, I know you're kinda old, but shouldn't your son be younger?"
"I'm only 38, you ass" Kyle retorted.
"It's because of the curse" Luke said shyly, "It made me older"
"What does he mean by 'curse'?" Trevor asked Kyle.
"He means the condition that makes me change races"
"Wait" Ike said, "does that mean you came on your kid!?"
"Of course not! What kind of freak do you think I am? It's passed on from generation to generation. That's why we call it a curse. My ancestors thought it was a curse on our bloodline, but it's probably just a genetic condition."
"But he didn't change race, he changed age. Is that possible?" Trevor asked.
"Well, I have heard of the curse making a few of my ancestors change race. Actually there are a few rumors of other changes too. But those were so rare and long ago that I thought they were tall tales until today." Kyle turned his attention to his son, "did you mother explain anything about how the curse works?" Luke shook his head no.
Trevor and Ike headed into the living room to give the father and son pair some space to talk. Trevor was impressed by how far reaching the consequences of his magic were. It seemed that in order for Kyle's race changing condition to become true, his entire family history was forced to change with that logic. Trevor would have to keep in mind just how powerful his ability to always speak the truth was. Still, he wouldn't let that get in the way of his fun. He was enjoying how well Ike had changed. He remembered how the giant's new mustache had tickled when he was licking Trevor in the shower, making the situation even more erotic. Trevor couldn't help but allow more changes to happen. "Can you believe Kyle's son changes age when he cums? What's more, Kyle said his ancestors could have had other things change about them."
"It's a freaky situation" Ike nodded, "I bet the kid's scared as hell."
"I'm sure it's not that bad. If his body is changing, he'll have mental changes too" when Trevor said that it became true. Luke had the same memories, but the slightly more mature mind of a 25 year old to match his body.
"I guess that makes sense. I just hope Kyle can return us both back to normal as soon as possible."
"I'm sure he will, you just need to let him cum on you a few times"
"Gross Dude, you sound way too happy about that"
"Sorry Ike" Trevor flashed an evil grin, "Hey, maybe you won't need Kyle. You already caught his condition right?"
"What do you mean?" Ike was falling right into Trevor's trap.
"His cum is contagious. If he came on you and you changed race, that means you caught the curse. Now when you cum, you'll change."
"What!? No way, it's just his cum that changes my race. It doesn't mean I'll always change race when I cum."
"No, I'm sure something else than your race or age will change when you cum. Kyle said there were other possibilities, remember?"
"Quit it, Trevor. You're just trying to scare me. It's not true." Ike scowled at his friend. Trevor simply smiled in silence, knowing everything he said would come true. He was excited to see how Ike's new curse would change him.
Meanwhile, Kyle remained in the kitchen explaining how their condition worked to Luke, "I change race every time I cum. As you already know, the race I become is random. I'm afraid it'll be the same for you, Son. You won't be able to control what age you become."
"So I'll probably have to do it a few times before I get back to my normal age" Luke nodded.
"You should also know that your, uh, partners could change too if they come into contact with... um"
"That naked guy asked if I changed because you came on me. Are you saying if I cum on someone they'll age too?"
"Yes, that's why you'll need to be extremely careful."
"So, you're middle eastern now, and he is too. Did you, uh, you know?"
Kyle turned away, unable to face his son in shame, "Yes, Son. I did."
Luke laughed, "Come on Dad! I'm 25 now, we can talk about sex" Kyle turned back to towards his son, surprised by his maturity on the topic. "So since it's random for you too, you'll have to do it a few times before he's his old self again" Luke thought about Ike becoming different races. He looked great as a middle eastern man, he was sure Ike could pull off any race. He began to absent mindedly rub his crotch, imagining Ike as a Japanese hunk like him.
"It seems like you understand everything, why don't we join the others?" with that settled, Kyle and Luke joined Trevor and Ike in the cabin's living room. "Sorry about the sudden change of plans guys. My son's a great kid though, so I hope you'll get along here."
"I'm sure we'll have fun. We're happy to have you here" Trevor smiled, "Luke, feel free to take a shower if you need to. I'm sure Ike would be willing to help you in there as much as he helps me".
