Make it a striptease.

"How about you both get naked?" Kazuma asked.

"Of course Master!" Fio replied as she and Cremea stopped dancing to reach for their tops.

"Ah!" Kazuma stopped them, raising a hand. "Did I say stop dancing?"

"Oh, sorry Master!" Cremea blushed, resuming the sway of her hips as she grabbed the bottom of her silk bra, and pulled it up, Fio resuming dancing outright. Cremea tossed the bra away, topless except for the fake jewelry on her arms that came with the outfit. She raised her arms and rolled her hips for him, smiling softly as she got into giving him his show.

Fio moved to turn around, rolling her ass as she moved to strip off the harem pants, opting to go bottomless before taking her top. She used the roll of her hips as she hooked her thumbs into the waistband of the garment to slide it down her hips and thighs before letting gravity do the rest and stepping out of them, waving her ass as she did for his viewing pleasure.

Cremea did much the same, only she was facing Kazuma as she rolled the harem pants down her legs. Now naked save for the decorations, she continued dancing, quite enthusiastic about it as Kazuma made it obvious how much he was enjoying the show. That left Fio to pull off her harem top, which she did swiftly, her body swaying and her curves bouncing quite nicely as she kept up the rhythm of her body skillfully all the while.

Now nude, the two danced around each other, completely lost in their endeavor of entertaining Kazuma.
