'This isn't happening', Brittany groaned in her head. She needed Santana. Santana was right there, bending over and tying her shoe, giving her a perfect view of her ass in those tight, tight jeans. She wanted nothing more than to walk over and slam her up against those lockers she was leaning into for support, spin her around and kiss her hard and fast, her tongue slipping in and – no.

Because she was mad at Santana.

And no matter how…how horny she was she wasn't going to let that fact slip from her mind. No matter how many people thought she was weak, thought she was stupid, she really wasn't. And Santana needed to be taught a lesson – which was that you can't just ignore Brittany S. Pierce and get away with it.

But Brittany had this well-known problem, you see. Well…it was a well-known problem to mainly Santana and her. She was two or three days away from her period. And it was around that time, in the short window before her period actually hit her that she got acutely, insufferably desperate for sex. Santana was usually overjoyed at the prospect of taking care of this problem. But for the first time in almost a year Brittany was both in need of something and unwilling to go searching for a random someone to give it to her.

And so she turned on her heel and walked briskly off to the choir room to sit out her study-hall alone. In silence. Maybe in the peace and quiet, with no people around, no Santana to fantasize about as she leaned over in her revealing shirt or twirled her pretty hair, she'd be able to control herself.

Just maybe.

Or maybe…maybe not. Because when Brittany arrived at the choir room she wasn't alone. Rachel was there, but instead of simply belting out some Broadway tune like she would normally be doing she was stretching her leg out using the lid of the piano, flexing it as if in preparation for dancing or playing a sport. Her head was pressed up against her smooth, revealed thigh and she was humming pleasantly to herself as she stretched out all the kinks, her hands rubbing at her calf muscles slowly.

Her skirt was so short! And Brittany knew that if she was between Rachel and the Piano as she did that stretch the brunette's leg would be thrown over her shoulder, and she would have a perfect, filthy view of her panties and what lie underneath them -

Brittany whimpered slightly, and then quickly clamped a hand over her mouth, her cheeks tinged red.

Rachel slowly lifted her upper body from its slanted position, showing a strip of skin as she stretched up, up, up… and then pulled her leg down from the instrument with a slight wince.

"Oh, hello Brittany."

"H-hi..." Brittany stuttered with a small smile, scuffing her converse on the floor and trying to look at the other girl's eyes, her hair, anything that wasn't below her neck, "what were you doing?"

"Stretching! It's always good to keep the muscles loose and limber. And I have ballet later today so –"

"Yeah," Brittany interjected in agreement, nodding her head rapidly, "That makes sense." She swallowed thickly. "I'm just here because um, because I –"God, she was awkward right now. But she had always found Rachel to be strangely likeable in her own way, and definitely hot. And right now, what with the level of hormones coursing through her veins she couldn't help but feel a rush of blood-flow heading south, the remaining color flooding her cheeks, as she blushed all the way down to her neck. As the blood all went downward so did her gaze, she realized Rachel's sweater had a wider neckline than normal, and she gulped.

Collarbones. Skin, caramel and so soft. She imagined it would taste really sweet, no matter where her lips, her tongue, her teeth went on their journey. Down, down….

"Brittany, are you okay? You seem…distracted."

"I'm good!" The blonde yelped quickly, her head jerking up as she tried to give Rachel one of her winning, dopey smiles. 'Quick, Brittany,' She chided herself desperately, 'think of an excuse! But you can't lie completely; you've always been bad at lying…oh! Got it!"

"Sorry Rach! It's just, like, 'that time of the month' for me really soon and I get cramps…yea, cramps. I came here to just sit in the corner and be alone, y'know? In my pain. Yep."

She tried to pout. It came out like a cross between a frown and a grimace. Her legs shifted together as she readjusted her stance and she nearly groaned again. Friction was not a good thing right now. No more friction. Unless Rachel was willing to give it.

Brittany did sigh a little bit at that, but not loud enough to be heard, at least she thought.

"I don't think that's what's really bothering you, Britt" Rachel stated with a nervous chuckle, moving closer to the blonde. "Usually…when I'm about to get my period, everything kind of turns me on."

Brittany stared, wide-eyed, nearly bouncing on the balls of her feet with nervousness as Rachel moved in closer still.

"Is that what's wrong right now, Brittany? It's okay if it is. Don't be embarrassed."

Brittany found herself nodding slowly, the blush returning again full force.

"Usually, Santana-

she cut herself off abruptly, thinking that wasn't information that needed to be shared. Rachel just kept looking at her, and soon there was so much eye contact, too much for her to handle, and Rachel was grabbing her hand, pulling her over to the piano bench gently and sitting her down on it.

"I can help you, if you promise not to tell." She straddled Brittany's hips, sitting in her lap with their noses practically touching, Brittany's back pressed oh so tightly against the covered piano keys.

"Rachel, what-

Brittany tried to protest, but then the brunette's lips tenderly met her own.

"Mmmph." She uttered, alarmed, but the noise allowed her lips to part and Rachel's tongue slipped inside, dancing around her own and – "Oh, God. Yea," she rasped, pulling away to look Rachel in the eye, her gaze darkening considerably; "Help me, Rachel. Please."

That was all it took for Rachel to let out a moan of her own, pressing her chest flush against the other girl and placing one hand on the piano behind Brittany's head, grinding her hips down hard as she ravished her lips and tongue with her own. Her teeth grazed Brittany's bottom lip as she slid her mouth off and down to the ivory skin of her neck, nipping at her pulse point suddenly and with little warning. Brittany cried out, her hips thrashing upwards, the fly of her jeans hitting Rachel's core, causing her to let out a soft cry as well. Her free hand that wasn't pressed against the piano had found its way to Brittany's waist and she quickly inched it up and under Brittany's shirt, finding a soft bra and slipping her fingers underneath it with no ceremony, caressing silky flesh for a moment before pinching an already hardened nipple.

"Raaachel" Brittany keened out, throwing her head back and giving the brunette much more room to work with as her tongue delved into a detailed exploration of her neck, "Rachel, you have to kiss me," she panted, "or touch me. Yea. Touch me. I need more."

Rachel lifted her head up and smirked, "You're the boss here Britt." She swooped in, quickly parting Brittany's lips again with her own, swirling her tongue against Brittany's seductively before pulling out again, sliding down and off her lap partially so that her feet were braced on the floor. She removed her one hand from beneath Brittany's shirt where it had been hard at work, the other away from the piano and pulled Brittany's shirt over her head before quickly removing her own. Brittany reached behind herself and unclasped her bra – the sight of her bare breasts alone was enough to launch Rachel forward again, her hands tangling in Brittany's hair as she tongued each nipple in turns, focusing on the left breast after the initial few licks, taking as much of it into her mouth as she could and sucking as her right hand untangled itself from messy hair and began massaging a trail down from Brittany's right breast, to her navel, slowly swirling her finger around it, to the hem of her jeans, nimbly unbuttoning them with a quick flick that her tongue mimicked up above. Brittany's breathy moans filled the otherwise quiet room, and she braced herself on the piano bench with both hands, widening her stance as Rachel slipped off of her lap completely, down onto the floor on her knees.

"Ready?" She asked with a wink, the teasing evident in her voice though it was huskier than it would have been several minutes before. Brittany took in the sight of the girl, clad only in a simple black bra and her sinfully short black pleated skirt and answered in an instant, the arousal and urgency evident in her voice,

"Take my pants off, Rachel."

"As you wish," Rachel drawled with a short giggle, reaching up and pulling at the blonde's dark jeans as she cooperatively lifted her hips in tandem with the motion. Jeans and panties hit the floor around her ankles in one fell swoop and Brittany was suddenly laid bare. Rachel groaned at the sight, immediately lowering herself to inhale her scent, breathing heavily into the girl's core.

Brittany squirmed. "Now, Rach, please…" she whined, lifting her hips up, showing clearly how much she needed it. Her nub was slightly swollen and her opening pulsed once with her hip motion, glistening with wetness.

Rachel didn't have to be asked twice, moaning as she pushed her face in between the girl's legs even further still, until her nose was pressing into Brittany's clit. She nudged it once, and the girl's hips bucked with such force that Rachel's hands were forced to fly up and over onto her waist, holding her down. She kept them tightly in place there as she gave the blonde's opening a tentative, curious lick. It twitched with the tender touch as Brittany moaned, and Rachel took that as encouragement enough to take it up a notch, pushing her tongue fully inside the girl and swirling it around against her inner walls with an appreciative rumble deep in the back of her throat.

"Fuck!" Brittany cursed, surprising the brunette with her out of character language, "touch my clit, Rachel. I'm almost there, I swear, I just need – "

Rachel pulled her tongue out of her tight hole slowly before thrusting it in once more, quickly and deeply. Brittany's eyes rolled up into the back of her head as her pelvis gyrated off of the bench, at this point not even touching it. The only thing holding her upright right now was a combination of Rachel and the straining muscle in her arms and hands, which were now shaking as she felt the familiar coiling of her lower stomach build, and build more and more until –

"Now, now, NOW" She yelled out in between grunts, her hips repeatedly slamming up, causing Rachel's tongue to slide in and out of her as she bobbed her head rapidly to try and keep up with Brittany's newly desperate pace.

Taking the blonde's queue, she pulled her tongue out wetly and shifted up slightly, making eye contact with the still thrashing girl as she sucked her pulsing clitoris into her mouth. Brittany landed back onto the bench with a loud 'thunk' as her hands let go and flew into Rachel's hair, pushing her head as tightly between her legs as she could get her. Her hips began jerking in rapid, small movements as Rachel's tongue swirled and twirled and her lips caressed. When she released the tortured bud only to press the tip of her tongue against it sharply in a quick jabbing motion, Brittany's moans became complete gibberish. Then Rachel sucked it right back in and bit down, hard, almost too hard, and she lost it. Every muscle in her body tightened as she pulled at Rachel's hair, her hips arching up and off the bench so abruptly that her head jerked back from the motion,

"" she cried out, and Rachel's mouth instead of pulling away found its way back to her opening. When Rachel's tongue was suddenly thrust deep and hard into her again, licking upwards against that spot, she found herself clenching up all over again. And as her second, sudden orgasm hit her with force her slick inner walls closed in so quickly that they pushed Rachel's tongue out, dripping with cum.

"Wow, Brittany," Rachel breathed out, lifting herself back up on her knees to look into the blondes face as her neck strained and her eyes snapped shut, her hips rocking forward a few more times even without friction to spur them on, "you're beautiful…"

"you're pretty great too, Rachel" Brittany giggled, dazed as she finally came back down from her high, "god, you're great…" she sighed happily and rested her head back against the piano with a thud.

Rachel grinned slyly, waiting for the blonde to make eye-contact with her again before proclaiming, "I'm glad, because I'm expecting full reciprocation when my cycle comes by…." She raised her eyebrows suggestively, but Brittany just sat up fully and blinked,

"I don't really know what that means."

"It means," Rachel intoned, "that next week, when 'my time of the month' is really close. You," here she stood and leaned down to tap Brittany on the nose, trailing her finger down to caress her lower lip as she spoke, "are going to return the favor."

Brittany's only response was to whimper in appreciation, and as Rachel leaned down to kiss her one last time, she had a combination of two thoughts cross her mind.

One, that she was sad she didn't get to taste Rachel's caramel sweet skin this time around, but she couldn't wait to very soon, and two, that surprisingly, she tasted pretty delicious herself – if the bitter-sweet residue on Rachel's swollen lips was any indication.
