"Ah, Master Simon," Beldazzar sighed. "Your wish is not altogether kind, but I thank you for granting me leeway so that I might make this to be the happiest outcome it might be. Since it would be cruel to torment these two foolish ones with memories of what they were even for a short time, I shall alter their memories such that they thought they ever were thus and moreover, shall make us invisible and inaudible to them, being as ghosts or djinn. Behold!"
Beldazzar waved his hand and suddenly Drake and Jake, the horny horses, were back in the room. He waved his hand then and Drake changed from a mare to a stallion, and then Simon watched as both slowly morphed back into Drake and Jake, but with slightly horsey dicks.
"Wow," Jake said, "I sort of blacked out there. What happened?"
"I don't know," said Drake. "I think it was the shock. I mean, I thought I was the only gay werehorse in the entire world. What are the odds that my new roommate would be one too?"
"I don't know," Jake said and smiled. "I think fate must have brought us together." As he said this, his cock swelled and grew longer, his horse balls engorging and then he started to shift halfway into a horse.
Drake, highly turned on by this, began shifting as well until there were two stallions standing in the room, licking and nuzzling each other's dicks.
Simon began chuckling at this, as it was one of the funniest things he'd seen, but Beldazzar gently chided, "Ah, Master Simon, it is now better than it was, but it is still not perfect. Please, make a wish that will allow me to make this all perfectly nice."
"I..." Simon paused. "I'd like to do something nastier, actually." He bit his lower lip. "Where am I getting all these evil and fucked up thoughts from?"
"Ah," explained Beldazzar, "when you wished you first wish, Master Simon, I regret to say that I was cruel and evil. Such cruelty and evil cannot merely go away, so I placed it within your heart."
"What?" gasped Simon.
Beldazzar shed a regretful tear. "Oh please, o master, forgive me. I was wicked when I did this, but I am a nice djinn now. Remember with what mercy still lies within your heart that there are good things in the world, and it would be an awful torment for a wicked and evil master to be served only by a nice djinn who wished to only to misinterpret his most perverted wishes and turn them into nice and happy things." Beldazzar bowed low before Simon while in the background, Drake and Jake still had gay stallion nuzzling. "Wish to be good again to spare yourself this torment."
Simon paused, then his look turned darker. "I think not, Beldazzar. After all, if I did manage to get you to do something horrible, you'd still be tormented yourself, wouldn't you? Like what's happened to these idiots?"
Beldazzar quailed. "Oh yes, o Master."
Simon chuckled evilly. "I don't think so. I think we're going to go visit a few more people and make a few more wishes first..."
