Perhaps consider a foursome?

"That was pretty fun," Denki remarked as they headed back into Denki's place, and Momo and Akemi started to undress without any need for Denki to say anything to them. Kyoka noticed and blushed.

"...yeah, it was," she nodded. "We definitely need to do that a little more often... Also, should I be joining them in nudity?" she then asked, pointing at Momo and Akemi.

"If you want to," he chuckled a bit.

She hesitated, but then looked at Momo and Akemi, who gazed at her right back, wordlessly urging her to do it. Crumbling under this rather unique instance of peer pressure, she started to undress herself, albeit more slowly than the other two. "So, what do you want to do right now?" she then asked.

Denki, working on getting his own clothes off, paused to consider. "I think I could go for another round, the question is, with who?"

"Oh, we should totally do a foursome!" Akemi raised her hand. "We can all give each other some pleasure with some rounds like that!"

"I second the motion!" Momo added, grinning. "Though this isn't technically a democracy." Even so, both she and Akemi knew that Denki took their opinions of potential activities into account.

"What do you think, Kyoka?" Denki inquired, turning to look at the slender Earjack Quirk user, who was just now sliding down her panties.

With a faint smile, she replied, "I'm down for whatever you want, Master... Within reason. I'm certainly not against a foursome..."

Denki nodded, and considered what position they should do it in.
