Let him make the wish!

As they settled in to find some good reading material, Ruby's mind raced. She had plenty of good options, she was just having trouble on settling on which one. Should she simply wish to know what Jaune's kinks and limits were? That was doable easily for Yang, but she wanted something a little more exciting. Then, she had an idea. She beckoned Yang over from one of the bookshelves, and Yang quickly obliged. As she approached, Ruby feasted her eyes on Yang's exposed breasts. She could never get tired of looking at them.

"Yes, Ruby?" Yang asked, grinning as she crossed her arms under her boobs to push them up. She knew where her Mistress was looking, and she very much enjoyed it. Her breasts were made to be eye candy, and as a being that couldn't get enough of pleasing her owner, Yang was quite happy to see Ruby wasn't holding back on looking.

Ruby allowed herself to be distracted for a solid fifteen seconds, before meeting Yang's eyes, and whispering, "Think you can grant a wish based on someone else's desires?"

Yang rasied an eyebrow and looked towards where Jaune was browsing old classic fairy tales. "I could. Where's this going?" she asked with some amusement.

Ruby giggled. "That's up to Jaune. I wish for you to grant his current strongest sexual desire that is compatible with our own goals and methods. As in, make sure it doesn't involve anyone who wants nothing to do with it, but does involve us in some way, within our own limits."

Yang grinned and snapped her fingers, sending out yet another pulse of magic.
