Maybe partway?

Lisa stared up at Jackie and gulped. "Um, that sounds like a lot. Maybe we could just hang out at a more human scale, and you could take some time out from that for your goddess activities?"

Jackie walked out from behind her heel. "No need for me to split my time. I can hang out with you and show off my giant body at the same time! Let me just take care of a few things." She paused for a moment. "There, now you're invulnerable, have the same freedom from consequences that I do, and we're in telepathic contact so you can request further changes, or just have high-speed conversations. Ready to go?"

Marie blinked as everything hit her all at once. "Now?"

Lisa turned to her. "Why not? We're allowed to cut class. We could even strip naked like Jackie."

Jackie looked down at herself. "Oh, shoot, I was so eager to get going this morning, and it didn't matter anyway..." She manifested a deliberately ill-fitting top that stretched over her nipples while leaving the bottoms of her areolae exposed, and a pair of daisy dukes that bulged around her crotch, while her cock snaked down one leg.

Marie licked her lips unconsciously at seeing the bulge in the pants. The fabric and the penis straining against each other made it so much hotter than when it was entirely free. Wait, she meant—

I don't mind.

We're friends. You don't mind me drooling over you like a piece of meat?

We're friends, and I won't let anything change that. Besides, if I didn't want people staring at my body, I wouldn't be showing it off like this.

"All right, let's go. How about we go to the beach, and on the way there, we can work on our beach bodies?"

Lisa blinked, still getting used to their new reality. "Work on them on the way? What do you mean?"

Jackie responded, "I'd be happy to give both of you any transformation and outfit you want. It's no trouble at all."

Lisa was a little uncertain, still. "Even if we keep changing our minds, or asking for absurd things?"

Jackie laughed disarmingly. "I have an infinite capacity for patience. If you think you can overwhelm that, you're welcome to try."

"Okay, let's go."

On the way to the beach, Lisa and Marie tried to make smalltalk, even as highly detailed fantasies of the bodies they could have developed and were put aside in their minds. So many topics of conversation were just no longer relevant, however. With Jackie's abilities, going to prom didn't mean anything, except if they wanted yet another opportunity to lord things over their classmates. With her knowledge, there was no real reason for them to bother with bachelor's degrees, and doing PhD work would be more akin to those idle games that took up a disconcerting fraction of the internet's focus. Suddenly, all that mattered were their fantasies, and they weren't yet comfortable discussing the details out loud, so they ended up mostly talking about hot guys and stealing surreptitious glances at Jackie's endowments.

When they finally arrived, Jackie stopped them in the parking lot and said, "All right, you're going to tell me what you have in mind for yourselves."
