Yes, and it's Petra's body!

"You know, there's one other thing we'd like to be seeing on this tour of this dream replica of Brigid," Sothis purred eagerly, making Byleth mentally sigh. She had such a one track mind.

Obliviously, Petra questioned, "Oh? What is it?"

"Why don't you give us the rest of the tour naked?" Sothis asked, clapping her hands together, and rubbing them.

Petra flushed, and replied, "Erm, while Brigid is fairly... Uninhibited, and lacks much of the body shame of Fodlan, walking around in the nude would still be rather attention drawing."

Sothis snorted. "This is a dream, remember? No consequences here!" she pointed out. Petra blinked, before nodding, realizing Sothis was right.

"Alright then... Though, have you not already seen me naked?" she questioned, casually grabbing the hem of her top and pulling it up.

"Of course, but seeing a girl, especially one as drop dead gorgeous as you, naked is just one of those things that never, ever gets old for anyone with a healthy libido~!" Sothis chirped, watching as Petra dropped her top.

"...while I can't say that's wrong, what exactly do you call your libido? There is such a thing as too much of a good thing, after all," Byleth deadpanned at her.

"No such thing!" Sothis mock gasped. She then gestured to Petra shimmying out of her skirt. "Tell me you're not enjoying that, and I'll tell you you're a liar!"

"I never said I wasn't," he replied, Petra giggling and straightening up, now naked.

"You enjoying the view, Master?" Petra asked teasingly, giving them both a twirl.

"...yeah, I am," Byleth nodded with a small smile. Sothis grinned eagerly, and floated over, before slapping Petra's ass.

"Ahn~!" Petra moaned, giving her rear a wiggle, and encouraging Sothis to give her another light spank. "Unh... Come on, let me show you more of my culture..."

"Lead the way," Byleth smiled as Petra turned, swaying her ass with each step, almost hypnotically drawing Byleth's gaze, much to Sothis's delight. Petra then began explaining the many spiritual and religious rituals Brigid did, before turning towards Byleth, placing her hands on her hips, and giving them a slight tilt.

"So, Master, would you like to see one of our dances to commune with the spirits?" she inquired with a smile.
