Combat Class

Ruby returned to her dorm room and went about the rest of her day normally after slipping Weiss's notebook back into its usual place. She felt as she usually did after a run-in with Cardin, depressed and a bit disgusted with herself at her continuing to take advantage of Weiss as well as the dirty feeling from Cardin groping her. She wouldn't even be in this situation if her weakness in studying hadn't gotten the best of her.

Things proceeded as normal the rest of her day, though she was highly embarrassed at walking around in her school skirt without wearing any underwear underneath. She couldn't really act as her usual high energy self and was more subdued, suddenly very aware about how the school skirt only came down to mid-thigh. She sat with her legs tightly together in every class and sat down carefully to make absolutely sure she was completely covered. Really she shouldn't have bothered. It's not like Ruby ever accidentally showed off what was under her skirt even when she was wearing panties.

But things were normal right up until Combat class. Ruby was changing from her school uniform into her combat clothes in the female locker room. She waited until her team was otherwise occupied and the row of lockers was empty before she dropped her skirt and tried to quickly squeeze into her usual huntress outfit. Unfortunately right then Yang choose to come back to her own locker and saw her little sister's pale bare ass right before it was hidden from sight by her black combat skirt.

"Ruby are you not wearing underwear?" Yang asked incredulously.

"Oh...uh...I forgot to put them on this morning." Ruby lied quickly her face turning bright red, embarrassed at having her sister catch her.

"You...forgot to put on panties." Yang said disbelievingly. "Ruby nobody 'forgets' to put on panties in the morning no matter what Mistralian anime would have you believe."

"Well I did!" Ruby said indigently, desperately hoping that Yang wouldn't dig deeper. "It's really embarrassing and I haven't had time yet to go back to the dorms."

Yang looked at her questionably before she shrugged and rummaged around in her own locker before she pulled out a yellow thong.

"Here, if it really bothers you then put this on. I have a few spares." Yang said offering some of her underwear to her sister.

Ruby paused and considered her memory of Cardin's threat of how if he found out she put on underwear today he would show off her bare ass to all her classmates. Then she considered how Cardin would actually check for such a thing. One of their only times alone was in the early morning during breakfast. Every other time the two of them were either surrounded by their team or were with friends. It's not like Cardin could just come up and flip her skirt in front of everyone just to see if she was still not wearing any underwear. She could avoid the bully for the rest of the day.

"Uh, thanks Yang." Ruby said as she took the thong from Yang. "You really don't mind another girl wearing your thong?"

"Jeez, don't make it weird Ruby or I might change my mind." Yang said as she huffed and shut her locker.

Ruby sighed with embarrassment as she wiggled the thong up her legs. Yang liked her thongs tight so it was rather snug even on her more petite frame.

She left the locker room ready for Combat class. Hopefully any of her fights wouldn't be too rough.

...........

Ruby coughed as she felt the breath knocked out of her as Cardin's mace impacted her chest. Flying across the arena, the silver-eyed huntress quickly maneuvered to cushion her landing on one of the sides of the arena.

She had been feeling off the whole match and when Professor Goodwitch had paired her up against Cardin Winchester she had panicked allowing Cardin to gain the initiative and dominate the fight.

Before she could recover from her rough landing Cardin was on her again and yet another strike sent her soaring before she could activate her semblance. Her landing was less graceful this time and she rolled head over heels until she came to a stop.

Then she felt the **** of her landing causing her skirt to flare up and fall forward. For a second or two Cardin was graced with the image of Ruby's thong clad ass before she yelped and smoothed her skirt back down. Cardin had a look of disappointment on his face as he advanced on the still kneeling girl.

"That's enough. Calling the match for Mr. Winchester." Professor Goodwitch yelled out. "Mr. Winchester, a good use of initiative and predictive thinking against a faster opponent. Ms. Rose, your hesitation cost you. Next time keep your focus on the match."

Ruby nodded dumbly as she shakily got back up. Cardin approached her for a friendly handshake to show there was no hard feelings. As they shook hands he leaned in.

"Main closet by the cafeteria after the last class. Show up or it will cost you more."

Ruby then went back to her team and waved off their concerns, internally filled with dread as she thought about what Cardin was going to do to her.
