She makes it to the doors

Just inches from the doors, Ruby stretched out her left arm, ready to slam the door open. She dodged the final person in her way, and suddenly she stopped in her tracks, some invisible **** holding her legs in place.

"YOUNG LADY, JUST WHAT DO YOU THINK YOU ARE DOING!" Glynda Goodwitch's commanding voice boomed out, her riding crop outstretched. She had taken a position on the dance floor, Ruby looked down, and saw a purple aura surrounding her legs. "I don't who you think you are," Glynda continued, "But public streaking is not allowed on campus. Since you so desperately want to show off, why do you come up here, and we can have a nice long chat."

Ruby was lifted into the air by her legs, leaving her hanging upside down. With a squeal, she quickly brought her hands to her private parts, **** to preserve her modesty as she dangled over the waiting crowd. Glynda kept her out of reach, but only by a little bit. As she floated over, she saw her teammates watching from the drinks table with looks of horror on their faces.

As she was brought to a landing, she desperately turned to the glowering professor. "Miss Goodwitch, I can expl-mmph!!" Ruby began, but was interrupted by her garter belt unhooking from her body and tying around her mouth, gagging her.

"Silence, Ruby Rose. I should have known it was you. All that potential, and you waste it by goofing off and pulling childish antics, never thinking about the consequences. It's high time someone taught you a lesson," Glynda growled, grabbing the arm that was covering Ruby's chest. Dragging her hand off her chest, she took Ruby to a pillar close to the dance floor, and shoved her against it face first. The purple aura flared up again, and Ruby's stockings flew off her legs, and onto her wrists, tying her to the pillar. Next Glynda used her semblance to grab one of the spotlights, and direct it towards Ruby, revealing her bent form. With the intensity of the light, the crowd could even see the glistening moisture on Ruby's pussy. Feeling the light hit, Ruby screamed into her gag, and began thrashing around, trying to get free. All it accomplished though was a show of her shaking her ass to the crowd. Behind her, she heard the sound of Glynda thwacking her riding crop against her palm.

"I think some good old fashioned punishment is in order here. Ozpin never lets me have any fun anymore," Glynda said, a sadistic edge to her voice. There was a whistling sound, followed by a _crack _as the riding crop hit Ruby's right ass cheek, leaving a red mark. Ruby screamed into her gag, tears forming in her eyes. "50 lashes, each cheek. You will think about what you've done, long and hard while I'm doing this. Clear?" Glynda said, and the hitting the each cheek. As she screamed, Ruby nodded vigorously.

"Good girl. Unfortunately for you, that compliance doesn't win you any favors," Glynda said, and then began her ****.
