Have her strip, and examines her body.

Jaune gazed at Yang, standing blankly in bare feet, an orange shirt a size too small, leaving her lower abdomen exposed, and black shorts... She looked so hot like this... Still, Jaune decided on an easy way to make her hotter.

"Strip naked," he told her. Without a word or any other acknowledgement, she reached for the hem of her shirt, and pulled it up, letting her magnificent hooters bounce free as she pulled it up over her head. Mindlessly, she dropped the garment, and then reached down to grab her shorts, and slid them right down her shapely thighs, and stepped out of them.

She stood there, mindlessly, her naked body on display in all of its wondrous glory. Jaune could feel his erection straining against his pants as he gazed at her. He walked up, and cupped her boobs a little cautiously. She didn't react in the slightest. He began to play with them, and still nothing. He grinned as he pinched and pulled her nipples.

Her skin flushed due to physical arousal, but in her entranced state, she could do nothing but stand and obey, and let him do as he pleases with her body. It couldn't even occur to her that she should.

He walked around behind her, and groped her ass, and ran a hand through her hair, failing to realize just how lucky he was she was unaware of anything with that last part. He then considered how to continue.
