Dustin opened the door, and Eli blushed and his hands went to his crotch to cover his dick. Ty wished for Eli to be wearing some clothes and for Dustin to forget he saw that, and giggled nervously. "Dustin, meet Eli!" he said once reality had been altered that way.
"Hey Dustin! Nice to meet you," Eli smirked, stepping up to Ty's foster brother and shaking his hand. Dustin shook back confusedly, surprised at how much firmer Eli's grip was than his. The two started chatting away, and Ty looked at Eli proudly, amazed that he'd turned the hot woman next door into this handsome boy and regressed Dustin into a little wimp who Eli towered over.
Slowly, Ty realized he couldn't stop staring at Eli's toned, firm arm muscles. He looked downwards, and his eyes involuntarily landed on Eli's soft, thick ass, which even through the boy's shorts he could tell was impressive. He didn't doubt the other side of his shorts was just as impressive, if not moreso...
For a moment, he recoiled at his thoughts. What the hell are you thinking? he told himself. Eli's your older brother.
No he's not, he corrected. He's your hot neighbour, who you just turned into a boy a year older than you. You don't look anything alike, for one thing.
Doesn't change the fact you're siblings, he thought.
It literally does, though, he realized. You could just wish for Eli to be your best friend and then this wouldn't be a problem.
Only at this point did Ty notice something about his feelings right now. He'd never felt attraction to a man before, but right now, he couldn't think of anything but how much he wanted to fuck Eli. He wanted to suck his big black cock and balls so bad. He'd love to lie back, present his ass to Eli and get fucked like a slut. He wished he could just kiss him passionately, and have the muscular boy hold him or push him down.
Looking down, he realized embarrassedly he'd gotten an erection from thinking about all this. He had a strange thought- maybe he wouldn't feel weird about this if he wasn't a boy? He could turn himself into a girl, and have Eli rail her and fill her pussy with cum. Then she could just put this weirdness down to him and Eileen wanting to swap genders for a while.
His thoughts were interrupted by hearing the door slam as Dustin left, and Eli turned to him with a big smile, quipping, "Thanks, Ty, that went pretty well." He looked at the boy with a shy smile, as pervvy fantasies raced through his head. What would he wish for? Or for that matter, would he wish for anything at all? Much as he hated to admit it, since it was basically nothing more than roleplay thanks to his power, the idea of fucking Eli while he thought they were brothers did sound kinda fun...
