Yes, but by keeping Faith where she is

"I, uh..." Willow blinked. "Buffy's my friend. I don't want to see her all... uh. Embarrassed."

"You're sure?" Faith said; she leant forwards, Buffy's admittedly modest tits still catching Willow's attention. The redhead swallowed.

"I mean, that's... really, really nice, but Buffy is... there might be something else!" Willow said, voice quickly becoming a squeak as she realised she was getting distracted. "If Buffy wants to swap back then she'll need magic. I can say, um, I can say it can't happen. Or it takes time. Delay her. You can still be all naked, and you won't be looking upset- Buffy won't be looking ups- you know what I mean!"

Faith cocked her head. Huh, so her time in Buffy's body wasn't over with. Now that could be fun.

"Meanwhile, seeing my body flustered and embarrassed and humiliated lets you work out your issues with me?" Faith said.

"Um. Kinda," Willow said. She flushed, then blinked as Faith only laughed.

"Nice to know you have it in you," Faith said.

She shifted, leaning back more casually. Now at least Willow wasn't trying to pretend she wasn't interested in staring.

So Buffy would ask Willow for help, Willow would lie and say there was no way to swap back, and she could keep on living like this. Nice and easy; and Willow got to keep on sharing a room with a naked blonde.

"Want to touch?" Faith said suddenly.

Willow squeaked.

"Figure you'd want to take full advantage of a Buffy you can do anything to," Faith said. She shrugged. "Sweetening the pot, if I'm staying here."

"I- I- uh- I-" Willow blinked, face scarlet.

Damn it, had she broken Willow? Faith rolled her eyes, chuckling to herself. Idly she stood up and sauntered over to her bed, laying on her front. Might as well let Willow see the rest of B's body.

"Up to you. I need a nap," Faith said. "Enjoy the view."

She stayed on top of the sheets, firm ass up in the air, well aware that Willow was still watching her. She could really get used to Buffy's body.

"What do you mean you can't help?!"
Willow faltered. Faith's body had always, well, contained Faith in Willow's experience. Contained a woman who, even if she wasn't, at least acted like she was in control, in charge. Certainly not someone whose voice could go so high-pitched and panicky.

Buffy stared back at her, by instinct crossing her arms over her chest despite the fact that the body she was in was fully clothed. Apparently just the thought of Faith in her body taking up nudism had her flustered.

"I, uh, her aura was out of whack when I saw her," Willow lied. "I could tell something was off, researched it all night but, uh, spells like that can't safely be undone without the original tool, and you said Faith broke that, so there's nothing anyone can do yet."

"You mean I have to let her keep going around in my body like- like that?!" Buffy yelped.

"Yeah," Willow said, trying not to seem too into the idea. "Maybe you can talk to her?"

"Have you tried reasoning with Faith?!" Buffy said, flushing. "Great. So that's all of California that's going to see my bits. That's... that's just great."
