They get pretty creative first!

"Hmm, hey, I got an idea," Denki grinned after a moment of thought.

Akemi put on a look of mock panic. "Well, thanks for warning us, bye!" she joked, acting like she was about to run.

"Haha, funny," he snorted. "Hey Momo, in addition to Kyoka's sensitivity in her ear jacks I wish that she could enlarge her ear jacks to about the width and length of my cock at will."

Kyoka froze and blushed as she realized that Denki was essentially giving her hypersensitive dildos as part of her body. "Granted!" Momo sniggered as she snapped her fingers.

Kyoka moaned as she felt her ear jacks tingle. Experimentally, she focused on them for a moment, and watched as they expanded. "...okay, wow, not gonna lie, that's actually pretty damn creative..." she remarked, moving them about.

"So what is the point of these enlarged ear jacks?" Akemi asked, now quite curious. "I mean, obviously, they're going in some holes, and not the holes they normally go in," she added with a snigger. "But I mean for the immediate bout of fun."

"Try to guess," Denki chuckled as he crossed his arms, already having an idea for the foursome in mind. Quirks and Sex Genie magic certainly allowed for quite a bit of flexibility in this particular department.

"...um... I'm guessing you want me to use them on Momo and Akemi's vaginas, that much is obvious," Kyoka mused, blushing.

"And you're going to be fucking her from behind while she fucks us with the ear jacks, right?" Momo grinned.
