Do this vanilla...ish, for now.

"Yang, stop" he said.

Yang immediately looked at herself in her current state and stood up, then grabbed her arm and rubbed it.

"Ow... why does my arm hurt?" she grumbled.

"You were just bouncing on it." Jaune shrugged "Anyway, that's not important right now. Yang, who are you?" he asked. She looked at him, perplexed.

"Uh... you alright Jaune?" she snickered "I'm Yang Xiao-Long."

"Right right. And what else?"

"Uh... A huntress in training? Ruby's sister? Your personal property?" she asked, stating all of these things as if they were the most natural in the world.

"Good. Good. And as my personal property, you'll do anything I ask?"

Yang shook her head and smiled.

"Duh. Why do you keep asking all these obvious questions? My main goal is to make you happy, so obviously I'll do whatever you want me to."

"So if I asked you to fuck me?"

Yang adopted a sultry expression as she moved closer to him.

"Oooh... THAT'S what your after huh, loverboy?" she cooed, whispering in his ear "I'll let you fuck me alllll night long if that's what you want."

Hearing that, Jaune's erection grew so hard it hurt. In an almost animalistic rush, he grabbed Yang by the arms. She looked at him in surprise as he tackled her onto the bed.
