He tests it on Ruby again.

He decided to give it another test and wrote, "Ruby Rose will head to an empty unoccupied classroom, followed by Jaune Arc, where they won't be disturbed, and then she will eagerly give Jaune a good time, pleasing him sexually however he likes for the next half hour, and when done, will revert to normal, without questioning what she just did, nor mentioning to anyone besides Jaune. She will consider it a fun time and want to do it more."

He put the Note away, and Ruby caught his eye, and excused herself from the group of students, and headed into Beacon. Jaune, heart pounding, followed. Once could be a very unlikely, very odd coincidence, but now there was no doubt in his mind that the Sex Note was the real deal.

As he followed her, he saw an empty classroom ahead of them, and expected her to go in, and was surprised when she passed it up. He wondered why briefly, but she entered another one a bit further ahead, and he shrugged, following after her and closing the door behind him.

Ruby turned towards him and grinned in what looked like an attempt at a sultry look, but just came across as cute and innocent. "So... I'm all yours. How do you want to do this?" she asked, shifting from foot to foot.
