Note: So this is my first attempt at writing an M rated scene, so please be honest, and try not to hate me too much if it sucked! I may or may not continue with this, but it's an idea I've been thinking about for a while, so let me know what you guys think!

Fifteen minutes had passed since the raven-haired orthopedic surgeon's pager had gone off. Unfortunately for her, she'd found herself in the wrong place at the wrong time and had her hands tied, stitching a deep cut on a young woman's cheek. Just as she was finishing the last stitch, her pager buzzed again. Glancing down at the small black contraption she growled inwardly, patience didn't seem to be on the menu today.

"An intern will be down within the hour to take you up for an x-ray, so just sit tight and we'll have you out of here as soon as we can," Callie told the young girl as she patted her shoulder and turned away to find someone to finish up the job. Spotting Lexie Grey loitering around, she rattled off instructions and handed over the chart. Just as she bounded through the double doors of the ER, her cellphone started vibrating in her pocket. Knowing exactly who it was, Callie growled and picked up her pace. Riding the elevator up to the 4th floor, she got off and all but ran down the corridor to the nearest on-call room. Inhaling deeply, she opened the door and slipped inside.

"You're late," sang a gentle voice from behind her. Callie heard the lock on the door click, and two arms slide tantalizingly slow around her waist from behind. Despite her best efforts to control herself, a shiver coursed through her body. The hands on her waist flattened themselves against Callie's stomach, pawing lightly at her skin through her dark blue scrub top. The silence that had taken over the room was interrupted by the sound of Callie swallowing, hard.

"I got stuck in the pit," Callie replied as she watched one of the hands at her waist begin to slide slowly towards the tie on her scrub pants. Her breathing hitched in the back of her throat as fingertips finally made contact with her skin. The hand at her waist inched gently lower, until fingertips had just barely grazed the lace of her panties. A whimper escaped the dark haired woman's lips, proving to only drive the hand deeper into her pants.

"Well," came a whisper from over Callie's shoulder, "I got bored waiting for you." Suddenly, both hands had been removed from her waist, and her body was being pushed backwards until her back made contact with the cold, hard wall. Finally, blonde hair came into view as a slightly shorter woman placed a hand on both sides of Callie's body, trapping her against the wall. Callie's eyes finally locked on the woman in front of her and she groaned painfully at the sight. Starting at her knees, Callie's eyes blazed a trail up the blonde's body. Her fair legs were bare, exposing her delicious thighs for Callie's eyes to feast upon. Eyes traveled further north, a pair of black lacey panties coming into view at her hips. A tongue darted out to lick over plump lips as Callie drank in the sight. Her hands lifted from her sides and immediately grasped the blonde's hips, pulling her flush against her own body. Callie's strong hands climbed roughly upwards, grabbing at the exposed skin of the blonde's torso. A growl escaped the dark haired woman's lips as her fingertips grazed over each rib in the blonde's chest on their way to her bra-clad chest.

"You started without me," Callie purred, her hands finally coming to a rest at the blonde's hips after grazing back down her upper body from her breasts. "Tell me, Arizona, did you lie in here and touch yourself?" Callie slowly began drawing circles on Arizona's hips with her fingers, every once in a while letting a digit slide just barely under the lace of her panties. She felt the blonde's body shudder at the contact and grinned to herself.

"I couldn't help it," Arizona whispered as she leaned her head into the crook of Callie's neck. Her lips dropped a few innocent kisses on the skin she found there, inching up towards her ear. "I started thinking about those deliciously long legs of yours, and before I knew it the throbbing between my legs was all I could think about," Arizona whispered against the shell of Callie's ear. Tracing the outside of it with her tongue. Arizona groaned lightly, "I couldn't wait to have you again. To hear you moan against my ear, to feel your thighs tightly wrapped around my head, to taste your intoxicating kiss."

Callie bit her lip, moaning softly at the words spilling from the blonde's mouth. Each gentle whisper sent a shockwave directly to her core, driving her mad with desire. Until now, the hospital had been off limits and it was definitely something Callie didn't want to rush. "Did you touch yourself?" Callie asked as she closed her eyes, trying to picture the sight of Arizona lying on one of the bunk beds with her hand between her thighs. Her imagination was quickly interrupted by Arizona's mouth latching onto her ear lobe, sucking on it and biting it lightly with her teeth. This elicited a guttural moan from Callie, only driving Arizona wilder.

Moving her head from the side of Callie's neck, Arizona locked eyes with Callie. Licking her lips at the sight of Callie's lust glazed eyes, she grinned, "Mhm." Her head nodded slowly as she drug out the sounds of her agreement. With her right hand, Arizona began caressing her own body, clawing at her breasts through her bra, raking down her stomach with her nails until she reached the fabric of her panties, gripping it tightly in her fist for a moment. "I closed my eyes and tried to ignore it. I wanted to wait for you, but I couldn't." Her hand let go of the fabric and slipped below it, cupping her sex with her hand. Arizona's lips parted with a silent whimper as she looked back towards Callie. The darker skinned woman's eyes were glued to the small space between them, watching as Arizona teased herself.

"Did you fuck yourself?" Callie asked, as her eyes grew wide. Arizona's hand had started moving, a finger tracing delicate circles across her clit. Self-control was getting harder and harder to contain as Arizona's face contorted beautifully to the ministrations between her thighs. Callie's hands found Arizona's waist, holding her steady as her legs began to tremble. The sight was enough to make Callie explode, but she didn't want this to end as quickly as it had started.

Arizona let out a weak moan, slowing the pace of her hand as she did so. "No, but god did I want to," she moaned, the thought of a finger inside her causing another growl to escape her lips. "I slid two fingers across my clit over and over again, trying to remember what it feels like to have your tongue licking and sucking," her mouth fell open again, unable to finish her sentence as a twinge of pleasure overtook her body. Steadying herself, she pulled her hand from between her legs, holding her wet finger out for Callie to taste. The olive-skinned goddess wasted no time, wrapping her full lips around the finger, swirling her tongue to lick off the juices. Callie moaned at the taste, officially unable to control herself any longer.

"Make me cum baby," Arizona demanded, thrusting her hips against Callie's, rolling them teasingly against her. That was it. Callie's hands found Arizona's hips and gripped her tightly. Quickly, she shoved the blonde backwards, knocking her down onto one of the small beds. Callie groaned again at the sight. Hair a tousled mess, blue eyes darkened over with pure lust, toned body half naked and a hand toying with her nipple through the bra covering her heaving chest. Lifting her scrub top off her body, Callie undressed herself to even the playing field. Practically ripping her scrub pants from her body, Callie finally joined the blonde on the bed.

"Where'd you learn to be so dirty?" Callie husked as she lowered her body on top of Arizona's, "It's so sexy hearing you talk like that." She pressed her lips against Arizona's collarbone and kissed softly up her neck to her ear. "I'm sorry it took me so long, but mostly, I'm sorry that I missed the show," Callie moaned against her ear. Arizona shuddered beneath her, hips bucking involuntarily against Callie.

"Touch me," Arizona groaned. She'd had enough of waiting, and was not above begging at this point. "Touch my pussy baby, please," Arizona whined, trying desperately to roll her hips in a way that would generate some friction where she needed it most. Callie grinned wickedly at her wanton display. With one arm supporting her above Arizona, Callie began torturing Arizona's chest with her free hand. Fingertips danced across heated flesh, nails dug into delicate skin, hands tugged bra-fabric up so that two gorgeous mounds of flesh could spring free. Locking eyes with Arizona, Callie's free hand began massaging a breast, kneading at the fleshy mound, tweaking a hardened nipple between fingers.

Rolling the hard bud between her middle and forefinger, Callie moaned at the sight of Arizona closing her eyes, sighing at the pleasure. "You like that?" Callie teased in a husky voice, "Mmm, your nipples get so hard for me." Arizona moaned again, her body starting to thrash against Callie's. Her back arched, begging for more.

"Fuck me," Arizona growled again. "Please, I'm so wet. I need your hand. I need you inside me." She bucked her hips upwards again, this time succeeding at maneuvering so that Callie's thigh fell between her own. Taking this as her chance, she lifted her hips, pushing down so that her panty clad center slid down Callie's thigh. Both women moaned at the contact.

"Fuck," Callie grunted. Wet was an understatement. Arizona had soaked through her panties and was now dripping onto her thigh. Allowing her to grind a few more times against her, Callie leaned her lips down to Arizona's neck once more, attacking the exposed skin with her teeth and tongue. She moved her free hand from the blonde's breast and slid it downwards. Taking hold of the lace panties, Callie tugged, hard, ripping the material from her body and tossing it to the floor. Another growl escaped Callie's lips as Arizona's now bare, heated center made contact with Callie's thigh. The feeling of Arizona's soaking wet clit sliding against her nearly sent Callie tumbling over the edge.

"Ugh," Arizona growled unapologetically, grinding her hips harder against the woman on top of her. "Please Callie, I need you to fuck me," she moaned, relentlessly gliding her clit against Callie had proved to be not enough. Callie was in a daze, her mind caught up in the tingling sensations of the blonde's clit sliding against her so effortlessly. Moaning in response to the plea spilling from Arizona's lips, Callie roughly pushed Arizona upwards on the bed, shimmying her own body lower as she did so. Plump lips drug a wet path towards the apex of the blonde's thighs. As an open mouthed kiss was placed roughly upon her hipbone, two strong fingers plunged roughly inside her.

"Ohh, fuck!" Arizona yelped as her senses erupted at the welcomed intrusion, her hips bucking forward at the contact. Callie moaned from her spot between the blonde's legs, relishing the sight of her hand buried inside her slick folds. Gently, Callie began to wiggle the tips of her fingers, curling them forward to brush just barely against that spot. A barely audible yelp escaped the blonde's lips as her hands tried to find something to hold onto, letting Callie know she'd done something right.

"You like that baby?" Callie coaxed, dropping feather light kisses on Arizona's inner thigh as her fingers worked at teasing her inner walls. The slew of moans that escaped Arizona's lips was enough of a response for Callie as she made her way closer to the delicious heat between the blonde's legs. Arizona growled, her hands flying towards Callie's head as the realization of what she was about to do hit her. Tangling her fingers in the dark locks, she nudged her closer, sighing with anticipation.

"Say it," Callie told her, using her free hand to push Arizona's hips away from her face. "Tell me what you want," Callie's tongue darted out from between her lips, running slowly along her bottom lip, "I know what I want. But, what do you want?" The fingers inside her slid out from Arizona's slippery core, only to plunge roughly back into her, over and over again. "I want to taste you," Callie husked out, licking her lips again in the process, "I want to feel your clit throbbing against my tongue, your walls squeezing tightly around my fingers. I want your thighs to shake around my head, keeping me locked tightly on you until I can lick up every last drop."

Throwing her head back, Arizona let out a deep moan, bucking her hips wildly towards her girlfriend, meeting her thrust for thrust. Hearing such dirty things spewing from the Latina's lips wasn't something new, but it never failed to drive her wild. But, she also knew that Callie meant business, and if she wanted to hear her scream it, she'd have to comply. Her body was on overdrive, and by now she'd gotten so wet that her juices had spilled out to coat Callie's hand, causing a delicious sound with each thrust.

"Ugh, harder," Arizona groaned out, hands still clawing at Callie's hair, urging her to dip her head just a little lower. The dark haired girl smiled wickedly up at her, making sure to plunge her fingers harder into the slick wetness in front of her. "Please," Arizona whimpered again, "Callie, please. Your tongue, I need your tongue." Callie dipped her head lower, placing her lips on a creamy white thigh, licking and sucking on the skin, making sure to leave a mark. "No!" Arizona all but screamed out in frustration. She'd been teetering on the edge for the last thirty minutes and now Callie was outright teasing her. "Lick me, please baby, lick my clit. Taste me, but please make me fucking cum," Arizona finally begged, tugging roughly on the dark locks until Callie's mouth finally came in contact with the spot she needed it the most.

Swirling her tongue around the hardened bud, Callie worked her fingers in and out of Arizona. Her arm had gone numb minutes ago, but she was determined to satisfy the blonde. Sucking her delicious bud into her mouth, she sucked hard until the familiar feeling of Arizona's thighs clamping around her head clued her in to the impending orgasm. Biting down slightly on the piece of flesh, she heard Arizona scream. Slender hips pumped roughly against her tongue as incoherent sounds filled the tiny room.

"Fuck, fuck, fuck," Arizona repeated over and over as she rode out the waves of the delicious orgasm Callie had just given her. Before she even knew what was happening, Callie had removed her fingers, licked her clean and scampered from between her legs. Glancing up, she found Callie standing across from her, quickly redressing herself.

Sucking in a few deep breaths, she managed to prop herself up on the small bed to watch her. "Where are you running off to so fast?" She asked her, slightly upset she wasn't going to get to return the favor.

"I've got a surgery in 15 minutes, and I thought we'd agreed not to do this here?" Callie asked as she tied her pants around her waist. The sight of post-orgasmic Arizona was almost too much for her to resist, but they'd set up boundaries for a reason.

"I get horny too you know, Calliope," Arizona husked with a sly smile, "You just happen to be the only one I know who can scratch that itch."

"You're married," Callie laughed, leaning down to kiss the top of Arizona's head. She turned to open the door of the on-call room and stepped out halfway before turning around again, "and 'straight'," she added before closing the door behind her. Leaning against it, she sucked in a breath. All of this was SUCH a bad idea.

Note: So, should I leave this a one-shot, or continue?!
