Fuck it, they go with honesty again.

Izuku nodded, deciding to tell Jiro everything honestly. Being honest about such things had worked for them so far, and they weren't doing anything wrong. Unconventional, yes, but not wrong per say. "Okay, but promise not to freak out? This is kind of hard to swallow," he cautioned her.

She rolled her eyes a bit. "I've seen some weird shit in my life up to this point, though this particular thing has gotten my curiosity. I think I can handle it."

Izuku nodded and walked towards his bag, opening it and rummaging around until he pulled out the lamp. "Girls?" he asked.

Momo and Ochaco nodded, and Momo let her legs dissolve into mist, the tip of which entered the spout, and Ochaco sank to all fours, sprouting her ears and tail again, the tail emerging from under her skirt. Jiro blinked, stunned. "Okay... What am I looking at?"

"A Sex Genie and a Neko," Momo replied bluntly, floating down to pet the purring Ochaco's head as she nuzzled into Momo's hands.

"...say what?" Jiro blinked.

"See... It's kind of like this," Izuku said, before explaining how the lamp had come from another dimension, bestowed Momo with incredible power and fulfillment in exchange for servitude to whoever had her lamp, and what they had done so far. He had of course wished Momo to put up a perception filter so none of the servants or anyone else in the house would find anything off should they pass by.

"...okay, this is a lot," Jiro admitted. "...so, you could basically make any girl you wanted do anything you wanted?"

"I could, but I don't," Izuku replied. "I don't make anyone do anything they ultimately don't want to do."

"Indeed, the whole harem thing is essentially my idea," Momo giggled, resting on her misty posterior on the floor as Ochaco rested her head in Momo's "lap." "And while we do plan to invite many others to join the harem, the most I do to facilitate the whole thing is remove their inhibitions at the time we extend the invite, so they can honestly be objective, and go based on that they want, and not what they think they should want."

"...and how do I know you're being honest?" Jiro asked, slightly on edge.

"You're not Izuku's **** currently, are you?" Ochaco giggled. "Though you might be in the future, or at least a girlfriend! If you're at least willing to consider it, we can talk again in about two weeks, if we decide to invite you!"
