He still has one more concern Momo can address.

"Okay, but there's still one glaring issue. The matter of consent," Izuku said after a moment of thought. "Even if we were both up for it... And I think we are, what if she wouldn't want it?"

"You might be surprised Master. I mean, making her a member of your harem isn't quite the same as me being a genie, but I didn't initially consent either, but I'm happy with the result," Momo pointed out. "I'd rub the lamp again a hundred times over if I could redo that moment."

"That's different. The lamp can't ask for consent beforehand. It just does what it's made to do," Izuku countered. "So it wasn't immoral for it. Amoral, but not immoral. That doesn't apply to us though."

"I suppose that's true, Master," Momo agreed thoughtfully.

"And for that matter, how exactly do we approach her with the question of, "Hey, you want to join my harem? We have a sex genie that can make you mine!"" Izuku added. "It's just not feasible!"

"Master, if I might remind you... Magic. We can approach this in a wide variety of ways if you decide to go for it. And you need not even violate her free will. We can ask her about it in a private setting, and if she declines, we can just have her forget so as not to blow our secret."

"...okay, that's a start, if we even decide to go for it... I still don't even know her that well," Izuku replied.

"I suppose... Though a little magic can determine if you both are compatible, you just need to wish to know," Momo giggled. "Still, we can always establish a system of getting to know girls and then inviting them to the harem, giving them an honest idea of what they might expect if they accept. Possibly a bit of magic to not outright mind control them, but remove any biases and insecurities instilled by societal pressures and upbringing for the duration of the conversation. A taste of the liberation I felt upon becoming a genie, but not making them do anything they wouldn't want to do... And if they refuse, we just wipe their memories of the interaction, and move on. Though I highly doubt many would."

"What makes you say that?" Izuku asked.

"Master, human beings are quite driven by sex. It's only societal upbringing, slut shaming, things like that that cause most people to repress it. The moment people stop caring about the judgement of others, and the only limit on their own desires they have is that things should happen between consenting adults, they'll be completely honest with themselves. It only takes five minutes in the Internet with Safe Search off to prove that point. The anonymity provided behind a computer screen is quite the uninhibitor."

"...as long as no one is being made to do something they don't want to do, we can workshop a system for getting a harem if you're set on it," Izuku finally agreed. "...I won't lie... I'm not against it myself," he then admitted.

"See? You'll be out of your shell in no time!" Momo grinned, booping his nose playfully.
