He has no reason to refuse

"Well, a wish to fix that might be of help," he remarked. He then told Aqua, "I wish I had a good amount of life **** so I could share some with Wiz without issue."

"Yes Master," Aqua said while snapping her fingers in what seemed to be a more melancholy manner than normal. "There. It's done."

Kazuma, noticing Aqua's demeanor, raised an eyebrow. "You okay? Answer honestly," Kazuma asked Aqua.

"I... kind of. Like my natures are fighting. She is an undead, but she's my friend... and you wanna have sex with her, so I wanna join in but she's an undead! Master! Ah!" Aqua almost exploded on the spot as she clutched her head.

"...what if I wished there was no conflict?" he suggested. "That your Goddess nature could accept undead who weren't causing trouble?"

"I can't deny the fun of you changing me. And anything my Master wants takes priority. But maybe... Not like that. You made it fun for her to be fucked by me. But I didn't get anything! If you want my opinion I think I'd prefer to get something for myself, Master."

"Well, what exactly do you want?" he asked her.

"How about my pussy is linked to her mouth, so when her mouth feels good, I feel good? That should be enough. Or you know, you could just wish she was alive again, that's good too!"

Before Kazuma could fully process that, he was interrupted. "Wah! Wait, wishing me alive? That... I uhm," Wiz panicked.

"There a reason you don't want that?" Kazuma asked her, curious, genuinely wanting to know about her story.

"Well, I have a spell up for... lets say an old friend and if I lost my lich powers, the spell my be disrupted and well, I would rather that not happen, so if possible, I would prefer my nature not being overwritten," she smiled brightly as she touched her fingers together. "If you don't mind that is."

"Fair enough. So, anything that doesn't affect her lich nature you can accept, Aqua?" Kazuma asked, turning to the Goddess/Genie.

"Hmm, well, like I said, can I have it so any feeling that passes through her mouth my pussy feels? Can we also make it so she needs to eat food like normal! Oh! And maybe make me like people more that make me orgasm!" Aqua almost shouted as she gets excited over the idea of improving her life with sex genie magic. "Oh my gosh Master, you have it so good! You can make wishes like this whenever you want!"
