Sisters Before Misters

A/N: To all those coming to this one from Lemon Requests, New content starts on chapter 5. Too everyone else, this is a series that evolved from a lemon I wrote for a request, and a lot of people seemed to enjoy it, so I wrote more, enough to justify making it into it's own fic. Enjoy.

Most big sisters, Yang thought, probably would assume their lil sis had a nightmare when they woke up with her in their bed.

Course, most little sisters probably didn't wake up their big sisters by straddling them and slipping a hand in their bra.

"Mm... Rubes, what're you doing?" She rolled her hips upwards and reveled in Ruby's surprised moan.

"Y'know, being a good leader. Gotta make sure my team is relaxed before their first big mission." Ruby flicked a thumb over a nipple, and gave a happy little sound as Yang tensed up.

"I- mmm, Ruby...I'm relaxed, trust me. M-may, shit... maybe you should ask Blakey?"

"I told you, that's not happening till your birthday." Yang was suddenly very aware of where Ruby's other hand was.

A well practiced finger entered her, and started rubbing around. Almost immediately, Ruby found what she was looking for, and Yang had to stifle a moan. "I ah, y'know... fuck... Ruby, when did you get so good at this? I'm pretty sure you'll have a tough time tahhhhh... talking her into it."

"Weird, you usually don't have that tough a time making sentences until after I make you come."

Yang pulled a face. "Well, you-fucking shit, fucking..." She grabbed a pillow and pressed her mouth into it to stifle a particularly large moan as Ruby added in a finger and began to speed up.

"Oh, you big baby. You're gonna come already?" Ruby asked, grinning.

Yang shook her head, and Ruby made her a liar by gently brushing her clit.

Yang's hips bucked into Ruby's hand, and the pillow barely succeeded in stifling the moan; for a moment, Ruby was certain Blake was waking up.

Yang's eyes begged her for more, so once she was certain they hadn't awoken the faunus, Ruby started up her movements again, adding in a third finger after a few moments.

"You know, Yang, I remember a time when I was proud when I got you to come. Now, you get all pouty if it's only once."

Yang glared, and moved the pillow to speak. Ruby, of course, chose that moment to brush her sister's button again, sending the blonde into a lusty moan.

Rustling movements made them both go silent, as Blake rolled over in her bed.

"You've gotta be quieter, Yang. Do you want Blake and Weiss to wake up and catch you coming all over my hand?"

"When did you become such an exhibitionist?" Yang managed to whisper between moans.

"Oh, like you haven't thought about it." Ruby says, pouting, and Yang opened her mouth to say something about it but Ruby let a fingernail just barely scrape against her clit in that way she knows Yang loves and all at once her second orgasm is ripping through her, so much more intense than the first and yet she didn't dare make a noise.

She's not sure how long she stayed there, shivering and silently coming in Ruby's arms, but Ruby tells her later that it must've been at least five minutes. Yang, of course, doesn't believe her.

Ruby looked almost disappointed, and Yang let out a surprised chuckle.

"Aw, Ruby, don't be so sad. You know, if they'd have woken up, you wouldn't have gotten a turn anyway."

Ruby muttered something, and Yang gently pushed on her shoulders. "Lay back, sis."

Ruby obeyed, looking slightly nervous as always, despite them having done this hundreds of times.

Yang tugged on her waistband, and she helped slide her pajamas down to her knees.

Yang smiled up at her, and grabbed hold of the shirt in one powerful hand. "You wanna leave this on?"

Ruby nodded, blushing as she always did. She tried and failed to meet Yang's eyes. She could feel Yang's hot breath on her thigh and she knew the blonde was smirking at her.

A finger brushed her, and she heard Yang's voice, as well as felt the vibrations from it. "You planned ahead tonight, huh? Or did you just not feel like wearing any?"

A nearly silent 'mmhmm' was her only response, and the blonde chuckles. "You know, to be such an exhibitionist, you sure are shy. "

Yang's breath is hot on Ruby' abs, and she can feel the muscles jumping in response. The ceiling is very interesting on this side of the room, she notes.

Yang's tongue, small and hot, traces across a muscle and Ruby can't help but whimper.

"You like that?"

Another whimper is her response, and as she ghosts over her eventual prize to kiss at a thigh, Ruby rises herself to meet her, letting out a moan at the contact. Yang presses a hand to her thigh and pushes her back to the mattress.

"Not yet..." She whispers, intent on teasing Ruby for all she's worth as payback for the younger girl's earlier mocking. She nips at a bit of skin.

Ruby reaches down and grabs Yang's hair, letting out a sigh of pleasure.

Yang froze up immediately. "Ruby, move your hands."

"Aw, Yang" She whined.

"No."

"Fine." Ruby said, pouting. She slipped her shirt the rest of the way off, giving her breasts the attention Yang can't. She lets out a small smile at Yang's appreciative sigh.

"You know, little sister, you're gonna have a nice rack one day."

Ruby huffs. "I already-" She breaks off in a moan as Yang catches her hood between her fingers, leaving her clit exposed to Yang's talented tongue. After a few mind-blowing moments, Yang began alternating between rolling her clit around with her fingers while giving long, slow licks up and down Ruby's core and sucking on her clit while gently rubbing at Ruby's g-spot.

A few moments of this and Ruby found her entire body shaking, until Yang suddenly stopped entirely and magnanimously handed her a pillow.

"Try not to moan too loud, okay?"

Ruby nodded wordlessly, her eyes glazed over.

Yang resumed her ministrations, and Ruby's hips bucked to meet her.

Before long, Ruby felt her climax approaching, and reached down to tap the side of Yang's head. The blonde smiled against her, and started rolling her clit between her teeth.

It wasn't until Yang curled her fingers inside of her that Ruby came, bucking wildly and letting out what Yang was sure would have been a truly glorious scream if she hadn't have been pressing the pillow hard enough against her face to leave the pattern of the fabric pressed into her skin.

The two spent a few moments pulling on their shed items of clothing before cuddling up and drifting off to sleep, falling back on the oft-used excuse of 'she had a nightmare' when the others send them odd looks in the morning.
