Planning to bring Mina in.

"So, Master, could you take the lamp back out?" Momo asked, shrugging off her uniform top as she, Ochaco and Izuku entered her bedroom.

Izuku blinked, but nodded, extracting the lamp, and her legs immediately dissolved into the tail again, attaching to the spout. "Ah, I forgot how thrilling that felt before doing it in All Might's office reminded me~." she sighed, getting the rest of her upper garments off as she floated.

"Pretty sure she'll be begging to be yours!" Ochaco giggled in agreement, standing naked now, and watching Momo float around Izuku. An idea came to mind. "...say, Master, I had a thought..."
