Make her strip.

"Alright Ren, show me your lovely body. Strip naked for me," Nora told Ren, who nodded, her delicate fingers moving towards the buttons of her uniform outer shirt. She began to undo them, blushing, but smiling softly as she complied with Nora's orders.

"Wonder if we should have changed Ren's outfit to the girl's uniform," Jaune whispered to Ruby, kicking himself for not thinking to do that as she managed to free his cock with her mouth, and gave it a loving lick. She chuckled a bit, and decided to wait until later to suggest adding that Ren's clothing would change automatically to match their current gender to the wish. She enveloped his dick in her mouth, and proceeded to slowly bob her head on him, sucking slowly and lovingly.

Ren dropped her overshirt, and then proceeded to unbutton and unzip her pants, pulling them down, revealing her slender legs and smooth skin. Nora proceeded to sit next to Jaune and Ruby on the bed, undoing her own skirt as she drank in the sight of her feminized long time friend undress for their viewing pleasure. "Mmm, that's it Ren, take it all off for me~," she purred.

Jaune moaned as Ruby fondled his nutsack, continuing to suck as they both also continued to watch as Ren got off her shoes and socks in addition to her pants, stooping down to do so. Barefoot, and dressed only in her boxers and undershirt, along with the tie she was now working on undoing as she straighened up. Pulling her tie loose, she then proceeded to undo a few buttons of her undershirt, and then reached for the hem. Gripping it, she slowly pulled it out. Jaune found his focus divided between the blojob Ruby was giving him, and watching Ren's midriff be exosed, inch by inch, until her shirt reached the underside of her boobs, and she pulled it up over them.

Given that she had been a guy until less than an hour ago, she wasn't wearing a bra, so her breasts were bare as they bounced back down into place. Ren got her shirt over her head, and dropped it, now clad in only a pair of boxers. At this point, Nora had pulled off her skirt and panties, before she began playing with her own pussy. "Last bit, Ren... take em' off!" she moaned.

Ren obliged, hooking her thumbs in the waistband of her boxers and sliding them down. Her glistening snatch came into view, and she stepped out of the undergarment, just as Jaune groaned, and came into Ruby's mouth. Ruby swallowed his seed before pulling off, leaving Jaune panting as Ren stood nude before them.
