"Ty," Lisa said. "My dad likes aquariums. I want him to see me in this form. My mom likes them too, but I know she doesn't like your magic."
"Well, you should probably get rid of the extra arms and breasts, then, and... um, shouldn't you put on a swimsuit, or something?" Ty asked. She was entirely undressed, and her breasts and nipples, even though they were transparent and water-filled, were plainly visible. Ty transformed away his extra arms.
"Oh!" she said. "I'm not sure if I have anything suitable." She shrank back to a single pair of arms and breasts, and started rummaging through her dresser. She found some shorts, which she put on. "I can't find a suitable top. Can you make a top for me? Oh I know! Even better! Why don't you make a part of my skin opaque and colorful, to look like I'm wearing a bikini top?"
Ty did that. "I suppose that's slightly more modest," he said. "The shapes of your nipples are still obvious, though. If you don't mind, I'll temporarily take away your nipples."
"That's fine," Lisa said. "And then that fish won't be able to find them and poke at them!"
Ty made the change. Now she looked modest enough, though just barely, to be presentable to her father. Though Ty noticed that you could still look into her breasts though other parts of her upper body. Well, can't be helped, he thought. He quickly got dressed.
Lisa followed Ty through the portal door back into her bedroom, and she turned the clock to normal. "I'm not sure I want Maria to see me this way," she said, "so would you go get Diego for me?"
"Sure," Ty said, and went out her bedroom door, closing it behind him. He found Diego in the dining room, just finishing his breakfast. "Hi, Diego," Ty said.
"Oh, hello, Ty! Good to see you. Have you seen my daughter?"
"Yes, we're finishing getting ready for school. Lisa is in her bedroom, and she'd like you to to see her... in a transformed state. It's an unusual transformation, but she thinks you'll like it. Just try not to be too shocked when you see her."
"Um, OK," Diego said, a bit apprehensively, and followed Ty up the stairs.
"She's not sure whether Maria should see her like this," Ty said. "And, of course, she won't use this form in public."
They entered Lisa's room, and Diego gasped. He stared at her for several minutes.
"I've always wanted an aquarium, dad," Lisa said. "So now I _am_ one! What do you think?"
"That's very... um..." Diego said.
"Do you think mom would freak out if she saw me?"
"Maybe I should give her a little warning, first," Diego said. "She does like tropical fish, but you know that she's not thrilled with Ty's magic."
"Well, Ty and I have to get ready for school, so why don't you think about that, and talk to Mom later. I think I want to have this form around the house, if it won't bother her too much. But for now, I'll transform back to normal, and go to school."
Diego said, "OK, Lisa," and went back downstairs.
