Ask her to strip.

"How... How about you strip naked?" Jaune asked, gulping slightly.

"Of course!" Ruby said in a chipper tone, starting by removing her belt and dropping it to the floor. She then deftly undid the red laces on her blouse and pulled that up too, the attached cloak coming off with it. Jaune watched in amazement as her body came into view while she pulled the blouse over her head, and then down her arms. Her bra matched her panties, white with pink dots.

She then knelt down, undoing the laces of her boots, and then pulling them. She stood again, and undid a button, then a zipper on the side of her skirt, and that dropped down. She stepped out of it and kicked it aside, now clad in only bra, panties, and her thick stockings that covered almost her entire legs.

She then hooked one thumb into a stocking, and bent to slide it down, before lifting a leg to pull it completely off. She then repeated the process with the second one.

Jaune's heart pounded as time seemed to slow as Ruby reached behind her back. He'd never seen anyone's boobs before, with the exception of one of his sisters, and that had been a complete accident, and he had looked away immediately, so it was only a glance.

Smiling coyly, Ruby unclipped her bra and slid it off her arms, allowing her breasts to be free, and on display for Jaune. They were small, but very well shaped, and her nipples were perky. That left only her panties on, and she hooked her thumbs in the sides, meeting his gaze as she slowly leaned down to slide the panties off. They soon dropped down her legs and she stepped out of them.

Jaune gazed at her in amazement, unable to tear his gaze away as she stood, crossing her arms behind her back and slightly twisting her upper body back and forth in an excitable manner, waiting for more requests.
