PROMPT: Blake is confused about Yang's sleeping habits.

WARNING, this chapter bumped my fic to M so please read with that in mind.

Enjoy.

There was something incredibly intriguing about the way Yang never slept under her sheets. Blake often wondered if her warmth could be trapped in there somehow, perhaps because the sheets had never really been lifted. Those thoughts always seemed to wander into Blake's head when she was alone in the room, free of scrutiny and the ever present gaze of her teammates. Blake sometimes found herself trying to reign in her very thoughts around them, inexplicably afraid one of them could read her thoughts with their semblance.

Her book lowering slowly, Blake's head pulled back, gold eyes fixed on the underside of the top bunk. She couldn't. The sheets would be left perturbed in a suspicious way if she got under them. But the idea of a warm bed and perhaps something that smells like Yang would be worth the anxiety.

And so Blake closed her book, placed it on the desk next to her partner and her's beds and swiftly jumped on the precarious bunk. Her form shifted awkwardly on the mattress before she felt it. Or rather, smelled it. Yang Xiao Long, blood, sweat and tears; but instead of smelling like such, her bed smelled of ...

Before Blake could help herself, her face was buried in her partner's pillow, inhaling deeply. Yang smelled comforting, like the familiar smell of a mother and yet... A shudder ran through the faunus, making her hand clutch the sheets tightly. No, a mother was not the right word, that smell wouldn't suddenly make her feel like her body was burning up. This was illusive and arousing. Blake sighed and decided to stay up here until she figured it out.

She didn't.

The second time Blake allowed herself to sneak in Yang's bed was less harmless. The other three girls had been gone since Friday night, gone home for a holiday. The sisters were looking forward to seeing their dad and Weiss was expected to show herself for the event planned by hers. Despite the adorable puppy eyes of Ruby and the disappointment in Yang's eyes (she disguised it behind a bright smile but Blake knew better), Blake assured them she would enjoy the alone time and promised she wouldn't devolve in her obsessive research. She was sitting on her bed, finished mug of tea on her desk and the latest Ninjas of love in her hands. Blake Belladonna was completely and irrevocably horny.

She blamed the book, of course. She had just finished reading the volume's big love scene and it got her riled up. Simple. She figured a cold shower would do the trick, not planning on relieving herself just because her corny book got her excited. But then her mind wandered. Her unnerving thoughts about Yang's bed; the scent of her partner came to mind again and Blake shuddered. One month after first really smelling it and she still could not figure out what it smelled like. She brought a hand to her forehead, feeling sweat pearling her skin.

"I really shouldn't."

Blake shuddered, wrapping her arms around herself. There was something incredibly magnetic about Yang's bed. The blonde had joked it was the height she enjoyed, her being a cat faunus and all. Blake bit her tongue then, trying to ignore the actual reason. Caving to temptation, Blake hopped on the bed and rolled under the covers for the first time. Instantly, her need grew tenfold, making her spine arc in a shiver at the overwhelming scent that came to her nose. Panting, Blake whined, pressing her face to the pillow. The scent was clouding her mind. Her thoughts were usually so ordered and put together. Right now she was a mess, a hot mess.

"Yang..."

The sound of her own voice surprised her with how needy it was.

Blake bit her lip, her hips pressing themselves against the mattress to try and relieve some tension. She briefly wondered if this was appropriate, but that thought flew out the window at the realization that hit her. Her hand gently cupped herself through her clothing and she brought it to her nose. Her eyes flew wide open as she confirmed this. Yang's bed smelled of 'Yang'. Her hands trembled and she absentmindedly brought the fingers to her mouth, the taste of herself making her want Yang desperately. Blake found her hand down her panties faster then she could weight what she was doing and what it meant. She decided that she would view Yang's flirting in a different eye now.

Touching herself, Blake pushed her face in the pillow, muffling the long sigh that escaped her lips. She wasn't a loud person, far from it in fact. The loudest sound she had ever produced in relief was a moan the equivalent of her everyday talking. But, she knew Ren and Nora were staying at Beacon for the weekend too, and she was paranoid. Being in a terrorist organisation until six months ago kinda did trick.

Pressing her front to the mattress, Blake gripped the sheets more tightly, hips still rhythmically pushing against Yang's bed. She absentmindedly realized she was basically humping her partner's mattress but her brain completely overlooked this information, focusing instead on the tremors running through her core. Her legs were tense and firm as a board on the mattress, making her feel weak too fast for her liking. She was far from done.

Pushing her free elbow against the bed, she pulled herself on her knees, pulling her lower body away from the sheet and planting her face and chest firmly on it. Her nose inhaled deeply, filling her lungs with the strong smell of her arousal and Yang's fainter own. If Blake had not being a faunus, she would never have noticed a scent so faint, probably the source never touching the actual sheets... Perhaps had she wiped her fingers on it after being done. Blake gasped, the mere thought of Yang, exhausted and spent, wiping her wet fingers on her sheets after touching herself was making Blake even more wet. Now that she had more space to maneuver with, she sank two fingers inside herself, another gasp escaping her lips. She shoved her face in the pillow and moaned a high pitch sob, drowning in the excitement of doing something so wrong.

Oh but it felt so good.

Her breath was heavy and uneven, her knees were sliding on the sheets from pushing too hard and she was so wet. In a daze, she marveled at how much thinking about Yang was getting her there fast. Her free hand gripped the sheet tighter, almost as if someone would walk in and rip it off her, exposing her indecency and pulling her away from this perfect scent.

She imagined Yang was right next to her, pleasuring herself alongside her, her voice loud and blunt as expected of the blonde. She was close now, her thoughts once again got a mind of their own and she was suddenly imagining Yang's hand over her exposed rear, cupping her cheek and rocking her along against her fingers.

That's when her orgasm hit her.

It was messy, and damp and her thighs felt like they were glued together but she slumped forward anyways; too spent to care.

After five minutes or so, or maybe it was ten? Who knew. Blake suddenly realized what she had done. She jumped from under the covers and hastily tried to reform Yang's 'messily made bed'.

"I am so fucked" she muttered.
