After breakfast Jaune quickly jotted down, "Ruby will make an excuse to go to the nearest unoccupied room, then strip naked, unaware of Jaune's presence"

Jaune made his way to the nearest empty room, being one of the classrooms.

Then he just... waited.

Soon his thoughts were immediately ensnared by Ruby when he thought of getting with someone because of his new, powers. Something about her small breasts, nice, round ass, and friendly personality was just so enticing for the purpose of testing the limits with this book and he’ll be getting more than just a quick look at her breasts.

Shortly after writing in the book, the door to the room opened and Ruby stepped inside. She closed the door behind her, seeming unaware Jaune was even there, and she began to disrobe. She took off her red hooded cloak and then shrugged off her as she stepped out of her boots. She reached down, lacing her thumbs into the tops of her stockings and flinging them off into her boots. She grabbed the bottom of her skirt and pulled it down after which she lifted her blouse off over her head, dropping it into the rest of her clothes, leaving her in only her bra and underwear.

Time seemed to slow as Jaune watched her hands reach behind her and unclasp her bra, letting it slowly drop to the floor, her gorgeous, medium size breasts bouncing playfully as they were released from their bindings, then her panties following suit, fully revealing Ruby's ass and pussy to him.

She stood in the pile of clothes, before frantically looking around, seeming to be concerned by her sudden nudity.

Jaune needed to begin his experimentation soon, because she would get dress and leave.
