She talks him into making a wish.

"Master, if you don't want them to come to the wrong conclusions about what occured, perhaps you should make a few wishes to ensure you are at least given a chance to keep my lamp," Diana mused.

"What do you mean?" Felix asked cautiously.

"I mean that my compatriots in the League might not exactly have an open mind regarding this," Diana replied. "Perhaps a wish to bypass their skepticism and sense that you can be trusted with it?"

"You want me to mind control your friends?" Felix questioned, skeptical of the idea.

She actually laughed a bit at this. "Not at all! Only bypass their biases and mistrust! Similarly to what the lamp initially did while persuading me become a genie! It essentially... spoke past my outer self, and more directly to my inner, true self."

"I don't know," Felix muttered. "It still sounds a little dodgy."

"Master, we both know you can be trusted," Diana replied with a smile. "It's just a matter of making my compatriots understand that too."

"But how would we even make that wish sexual?" Felix asked, considering it.

"Master, there's a clear motivation to at least potentially keep a Sex Genie," Diana answered. "Just work a mention of that into the wish, and it's doable."

Felix paced some more, thinking it over. He did in fact want to keep Diana. Who wouldn't? Even if he planned to use her power in an at least mostly responsible manner, the idea of Wonder Woman being his sex ****, and actually happy about it, and boy, he could tell she really was happy about it, was so appealing. He decided the wish was harmless, and decided to go for it. "Alright... to increase my odds of being able to keep you as my... Sex Genie, I wish for everyone in the League who ends up privy to this matter will know how much I can be trusted. And I don't mean I want them to trust me unconditionally, just... know exactly if I can be trusted." After all... despite what Diana said about her conditions for the lamp, he wasn't entirely sure about if he could be trusted.

"Done! Now, let's get going, shall we?" Diana asked.

"Um, can you make legs and change back into your clothes, first?" Felix asked her.

"I am wearing my clothes, Master... oh, you mean what I was wearing before I was turned?" she asked, detatching her tail from the spout of the lamp, and it split in two, condensing back into her sexy legs.

"Yes, that," he nodded, before she obliged, her harem outfit dissolving into mist, leaving her naked, causing him to blush, before returning to her original outfit. With that, they stepped out of the alley.

A red blur approached them. "Daina?" Flash asked as he stopped. "We were just starting to wonder where you were."

"Heh... it's quite the long story, Flash," she smiled at him. "We should gather the others and return to base... and we also need to bring him along," she gestured towards Felix, who was shifting uncomfortably.

Flash looked at Felix, curious, but knowing that Wonder Woman had a reason, and nodded. "Alright, but you know you're going to have to explain why a civilian is coming along." He dashed off.
