"So he shall," Beldazzar intoned, "your wish is granted...in a way that will not harm him, of course."
Simon was instantly worried. Who knew how this stupid nice djinni would twist that last wish? Simon silently cursed his stupid, rash wish. He was about to tell Beldazzar to cancel the wish (he hoped that would work) when his entire body tingled and bucked, as if a jolt of electricity had just passed through him. He looked down, and saw that he was rematerializing, in Mark's room. But the body was not his usual one! Instead, he looked down upon a pair of unusually magnificent breasts, round and full and smooth. He looked up into the mirror on Mark's closet, and a sexy, scantily-clad woman looked back at him. He looked higher, and saw the poster of the huge barbarian that Mark had become; an identical woman was on the poster, kneeling, one arm wrapped around the barbarian's thickly-muscled thigh.
"Princess!" boomed Mark's deep voice.
Simon looked over at the huge man who rushed toward her like an avalanche. Simon put her hands up, but Mark easily picked her up and embraced her, his massive arms and jutting pecs as hard as iron.
Simon's mind became fuzzy. He was Simon. He was Princess Esmerelda. She was Simon. She was not Simon. The huge figure holding her was Mark. But it was Gar, barbarian lord of Cardor, her bodyguard and lover. Her servant, of sorts.
Oh crap.
Simon realized how Beldazzar had twisted his wish. Mark was not being harmed. But apparently, that "nice genie" thing didn't extend to Simon!
"Actually," Simon/Esmerelda heard Beldazzar say in his/her mind, "I couldn't think of any other way of granting your wish. One of you had to be harmed. I made the harm as minimal as I could."
Simon was fading away, and Esmerelda was becoming stronger. "Gar, my love," she purred, "it has been soooo long..."
Mark still had his mind. But he knew all about Gar and Esmerelda - he had all the novels, after all. "What do you command, majesty?" he asked, grinning.
Esmerelda leaned in and kissed him deeply. "Fuck me, my love," she whispered.
