Mei has some thoughts!

Izuku sat up, and Mei did the same, settling herself on his lap, and leaning against his chest, crooning all the while. She grabbed his hands, and brought them up to her breasts. "No reason not to feel good while brainstorming, right?" she asked him with a wink.

"Guess not... so... how to aid you in creating your... babies, while involving sex?" Izuku mused, idly playing with her sizable assets. She sighed happily, leaning against him.

"I think I've actually been missing out," she admitted with a giggle. "But first of all... I think this dreamscape would be a good place to start... I'd like the ability to have a fully functional and stocked workshop in my mind while I sleep, one that functions exactly as it would in reality. I've dreamed up inventions in my sleep before, but the problem is, even stuff that wouldn't work in reality work perfectly in said dreams, so I learn nothing from it!" she pouted.

"Makes sense, ribbit," Tsuyu noted, the other five girls nodding in agreement.

Izuku nodded thoughtfully. "Sounds good... Probably safer that way too, if you do all of your failures in here, and recreate your successes in the waking world... but how to involve sex in it?" he mused, pinching her nipples lightly.

"Mmmnh!" Mei moaned, biting her lip. "Well, there are the obvious ideas..."

"Right, if you included sex toys in the things you planned to invent, that could work," Izuku noted. "I'm curious to see how creative you could get."

Suddenly, Mei had a gleam in her eyes, clearly having an idea. "Oh, I just thought of something that could be considered the mother of all babies!" she cackled gleefully, even as she squirmed atop Izuku's lap. "Something that could be used for sex, too!"

"Do tell!" Momo chirped, curious as she leaned in. "Whatever it is, I'll gladly provide materials if you need them if it's good enough!"
