Yang roared as she drove her fist through one of the many stone walls of Beacon, her fist tearing through it like paper...again.
 
 
Beacon's resident blonde brawler was having a rather...off day, to put it mildly, as she was going through the process that every woman of age has to go through.
 
 
Her period.
 
 
While this in itself doesn’t sound so bad, the fact that Yang had already punched holes through at least several dozen walls throughout Beacon would say otherwise, though fortunately, she hadn't attempted these maneuvers on any students or teachers, as they all were wise enough to run and hide from Yang to avoid her wrath.
 
 
Needless to say, the lack of a training partner to vent her frustrations on riled up Yang even more than usual.
 
 
As she stomped away from the newest hole she had made, she didn't realize that on the other side, having positioned herself just underneath the part that Yang's fist had traveled through, was Velvet Scarlatina, alongside her entire team, the other three members having backed away from the spot as fast and as far away as they could, while the poor bunny girl trembled on the spot, having been made too scared to even think of moving.
 
 
"Goddamnit!" Yang shouted, her head slamming itself into another wall in rage. "I fucking hate my periods!"
 
 
While Yang attempted to (so far unsuccessfully) vent her anger, in a nearby room, was the villainess-in-disguise Cinder Fall along with her teammates, Emerald, Mercury, and Neopolitan, and the group was currently listening in onto Yang's frustrations
 
 
"You still want a go at her Mercury, now's your perfect chance" Emerald remarked dryly.
 
 
Mercury shook his head, he may be an excellent fighter, but even he wasn't dumb enough to willingly get in the path of a violent Yang.
 
 
Cinder sighed, before reaching into her pockets and pulling out what looked like a purple Dust crystal. "I'll see if I can't calm her down with some Calming Dust, anybody want to help out?"
 
 
The trio looked at Cinder as if she was crazy, which probably wasn't too far off.
 
 
"How about you Neo?"
 
 
In a flash, the ice cream girl teleported, her form shattering like glass, and leaving nothing behind.
 
 
"Emerald?"
 
 
The green haired girl jumped out the window.
 
 
"...Merc-"
 
 
CRASH
 
 
Before Cinder could even finish, Mercury had run straight through the wall behind her, leaving only a trail of dust and a human shaped hole behind.
 
 
"...Cowards..."
 
 
As she left the room, she failed to realize that the crystal she grabbed was VERY similar to a similar lying on the bed nearby.
 
 
-----------------
 
 
Yang smashed her fist through her sixth punching bag in a row, the limb tearing straight through the material and sending sand all over the floor, causing the blonde to scream in frustration, before ripping the remains off its chain and tossing it aside.
 
 
Currently, she was in Beacons training room, trying to vent her frustrations out, though her amusement of the equipment did nothing to quell her anger, and in fact, somehow seemed to drive her temper up a couple notches.
 
 
She slammed her fists into the wall, cracking it. "Can nothing calm me down?" Yang whispered.
 
 
"Perhaps I can be of assistance."
 
 
With the greatest amount of restraint possible, she slowly turned her head around to see Cinder approaching, while holding a purple Dust crystal in her hands. "I've got some Calming Dust you can try absorbing, maybe that can quell your anger a bit" She said calmly, seemingly unaware of the raging inferno standing before her.
 
 
Yang didn't dare try to get closer, and instead, simply stretched one hand out, which Cinder deftly tossed the crystal into. As Yang grinded the crystal into a fine powder with her bare hand, she immediately felt its effects, her anger rapidly spiraling downwards.
 
 
For the first time today, Yang smiled, her usual demeanor returning to her.
 
 
"Thanks Cinder, I guess I owe you one"
 
 
Yang turned around to face her, but Cinder was already heading towards the exit, her hand casually waving back. "Anytime"
 
 
As Yang watched her leave, she soon felt something stir inside her, something primal, something erotic, something...predatory.
 
 
As Cinder walked back towards her room, she felt something slam into her back, sending her face first into ground.
 
 
"Gah! What the hell?!" She turned her head slightly, and was able to see Yang on top of her, staring at Cinder with a lustful, almost predatory look in her lilac eyes.
 
 
"Yang, what are you do-MMPHM!?!"
 
 
Cinder was interrupted when the blonde smashed her lips against her own, tongue interlocking with hers, causing a blush to creep up Cinders neck.. She tried pushing Yang off of her, but Yang proved to be too strong for her, this being evident when the blonde started tearing her clothes off with one hand, while pinning Cinders right arm with the other.
 
 
For a brief moment, Cinder was able to pry Yang's lips off her mouth and shout out an angry "Get Off!!", but was quickly overwhelmed. As Cinder pondered what she did to deserve this, Yang had ripped off the last of her clothes, leaving Cinder buck-ass nude on the floor, her facial features a mixture of anger and embarrassment.
 
 
As Yang leans off of Cinder, and practically tears off her own pants, Cinder finally gets to voice her thoughts.
 
 
"I don't know what's gotten into you Yang, but you need to stop, before I decide to hurt you!"
 
 
But Yang didn't seem to notice, or care really, as she took her yellow panties off and tossed them aside, her eyes never leaving Cinder. Without warning, Yang grabbed Cinder's feet, and shoved them up her vagina, much to Cinder's shock, and Yang's pleasure.
 
 
"What on Remnant do you think you're doing?!"
 
 
To Cinder's misfortune, Yang was lost in her own little world of pleasure as she began pulling Cinder's legs into her womb, which slowly stretched outwards as Cinder's lower torso began to occupy it.
 
 
The pyromancer tried struggling to get away, but her legs were forcibly pinned by Yang's snatch, and when she tried punching Yang in the face, the blonde quickly pinned her arms to her own sides.
 
 
Cinder cursed up a firestorm as her hips and hands were engulfed, followed by her stomach, with Yang moaning loudly all the while, as her body sucked Cinder up. When the blonde had managed to engulf Cinder all the way up to her neck, her abdomen had swollen up to nearly the size of a beach ball.
 
 
Despite Cinder's vision being blocked by Yang's swollen abdomen, you could tell she was glaring. "I swear, when I get out of here I'll MMPHMH!!"
 
 
Yang let out a throaty moan of pleasure as her snatch engulfed the last of Cinder, causing her to orgasm, and pass out on the floor, her abdomen bulging and wriggling violently.
 
 
…
 
 
From his office, a familiar white haired man raised an eyebrow as he watched what had happened unfold.
 
 
“Well…” Ozpin remarked. “That was interesting…”
