Mei wants a bit more fun first, and hashing out the details of the wish!

"So, how about we talk about the specifics of how the wish would work, while I try my hand, or rather, mouth, at giving you head?" Mei suggested to Izuku, giving him a seductive wink.

"...if you want to," he smiled, and she got off his lap, turned, and got on all fours before him, lowering her face to his manhood. She began licking their mixed fluids, before pausing.

"Oh, that tastes nice~!" she admitted, before licking more.

"Result of a past wish," Momo supplied helpfully. Mei grinned, and engulfed his shaft, caressing his balls as she sucked, and bobbed her head. Her efforts were a bit clumsy, but pleasant for Izuku nonetheless.

"Unh, nice," Izuku panted, reaching down and patting Mei's head. "So... About that dream workshop..."

"Literally," Mei chuckled, pulling off to stroke his shaft so she could speak, before returning to suckling his cock.

"Yeah..." he moaned. "I'm thinking each night we don't have sex in one of these dreams, you'll have a top of the line workshop to experiment in... And it will remain in whatever state you left it in next time you wake up, unless you ever want otherwise, like saving in a video game," he mused through his pleasure, bucking his hips slightly. "Also make her immune to any damage from explosions if she isn't already in the dream."

"Mhmm!" Mei nodded around his shaft.

"And to keep a sexual element, wording for developing sex toys, and a potential sex android should be included," Momo nodded.

Izuku grunted in agreement, before making the wish, carefully wording it to include all of the details mentioned, before cumming in Mei's mouth. She gulped it all down greedily. Once that was done, she stood and pumped a fist. "Yay! More time for my passions!" she celebrated. "Enough extra time to spare some for a sex life too!"

The dream started to fade, and Izuku said before it ended, "I'll be stopping by the workshop in the Support Course tomorrow. I have a job for you, actually."

"Can't wait~!" Mei replied, before they all would awaken.
