They take it relatively well.

"...yeah, I'm definitely dreaming," Kirishima stated. "No way there are such things as Sex Genies."

"Oh, I assure you, this is happening..." Momo giggled. "Neither of you are dreaming... well, you are, but it's real regardless. We're all brought together into the same lucid dream by my magic..."

"...speaking of which, we both know Ochaco doesn't want to miss this," Izuku replied. "Momo, I wish she'd just fall asleep."

Momo smirked and snapped her fingers, and Ochaco appeared in the nude, laying prone in a sleeping positon, before opening her eyes and sitting up, grinning. "Sorry I'm late!" she waved.

"No problem, perfectly understandable..." Izuku told her. "I had to train all day to ensure I could sleep myself..."

"...so... if this is real, and Momo is a Sex Genie..." Mina mused. "Wow, just... wow... that's amazing. And we thought Mineta had reason to be jealous of you before," she giggled.

"...if we do wake up to find out that this is all real, we are not telling anyone, least of all him," Kirishima told Mina. "If the little gremlin did find out, I see no scenario where he does not commit "Suicide by Midoriya.""

"Yeah, he wouldn't rest until he got his hands on the lamp, would he?" Mina chuckled. "Don't worry, I may like to gossip a little, but I do know where to draw the line... but that brings me to our question. If this is real... why are we here?" Mina asked Izuku and Momo.

"That is a good question indeed... why bring you both here, with your inhibitions suspended so you can actually objectively measure your own desires to the situation you're in... It's quite simple really," Momo started to explain. "We have something of an offer for you both."
