Author's Note: Welcome, welcome! You may have been directed here after reading my compilation "Words of Love," a series of romantic one shots using words going from A-Z. Well this is the exact same thing, but smutty version. It will be a series of twenty six oneshots, all based on one word prompts. It's rated M to be safe, but not every chapter will have an actual sex scene, they'll all vary in level, but I promise they'll be lust riddled. Anyway, hope you enjoy!

Arousal: (noun) to be stimulated with sexual desire.

Throughout the years, over the span of hundreds of cases, Mulder had shared countless adjoining rooms with Scully. Since they usually kept the door open, they saw sides of each other that they didn't share with anyone else. He had seen Scully in every color facemask available, they would have conversations while he was clipping his toenails, they've had to apply aloe to each others' sunburns, so many intimacies shared between partners.

Even when they said their goodbyes at night, finally closing the adjoining door, he let himself fall asleep by listening to the sounds of Scully on the other side of the thin motel wall. Ninety-five percent of the time, it was the same routine every night. He would hear her sock-clad feet padding against the carpet after closing the door, followed by the sound of the keyboard against her fingertips as she finished her case report, then she either showered, or went straight to bed. Scully was a heavy sleeper, he knew that from all the times she had fallen asleep on him, so when he heard the lamp click off, he knew she would toss and turn for a few minutes before succumbing to sleep.

However, the other five percent of the time was a completely different case.

The first time, he had no idea. He was laying in bed as usual, when he heard the lamp click off. Instead of tossing and turning though, he heard rustling, as if she was trying to burrow into the bed. After a few moments he heard small gasps, they were quick, so he wasn't even sure he had heard right. Before he had a chance to listen furthur, he got a phone call from the Sheriff letting him know another body was found and that he and Scully needed to report back. Mulder was only half paying to the conversation, mostly trying to focus on determining if he was hearing whimpers.

When he rolled out of bed, the noises became quieter, as if she was alerted by hearing him through the wall. He walked a few feet to the door and knocked loudly. There was a moment of silence before Scully's strangled voice called out, "Give me a second." Her voice sounds higher than normal.

Mulder stood at the door, picking at his fingernails as he heard Scully get off the bed, followed by some undetermined rustling. Finally, after turning on the lamp, she opened the door. He was immediately concerned. Scully's cheeks were rosy and flushed, and it looked like she had some light sweat smattering her forehead. He also noticed she was reluctant to make eye contact with him and was breathing funny. He placed a finger under her chin so he could get a better look at her face. "Scully, are you feeling okay, you look flushed."

"I'm fine, what do you need?" She kept flitting her gaze from him to the floor, but she had kept contact long enough for him to see that her eyes were dilated and glazed over.

"Do you feel warm? Do you have a fever?" He moved one hand to cup her jaw while he placed the other across her forehead. She felt warmer than normal, but she had seemed fine all day.

"Mulder, I said I'm fine. I'm a doctor, I would know if something was wrong. Now why did you knock?" She gripped his wrist with her right hand, and he was immediately drawn to the heat that emanated from her index and middle finger. Looking down, he noticed those two fingers were flushed pink compared to the others. When he looked up, he noticed in the reflection of the mirror behind her, that he could see the tag of her pyjamas sticking out. She had put on her shorts inside out.

The realization hit him like a truck; Scully was just masturbating.

He wanted to punch himself for not realizing it sooner. It all made sense. The noises, the flushed cheeks, the sweating and panting. She wasn't sick, she was aroused. She was preoccupied when he knocked, and so, in her daze, she put her shorts on inside out. She was breathtakingly beautiful this way.

Not wanting to embarrass her, but knowing his blush, and something else, were growing, he released her and took a step back. "I got a call from the Sheriff, they found another body and they want us at the crime scene."

He wanted to laugh when Scully practically whined, "Right now?" Scully is standing in front of me pouting because she didn't get to cum. He felt like he was in a fantasy.

"Sorry, Scully. Coffee's on me though," he offered hoping to brighten her mood. "We should be back before you know it." She gave a slight nod before closing the door so she could get changed.

He let out a long sigh before standing up straight. He didn't need to check, he knew he was hard. Dana Scully was just finger-fucking herself with only a wall separating us. He felt his cock twitch at the thought and he realized he was in the same boat as her now. What he wanted more than anything in the world was to shove his hand down his pants and lose himself to the fantasies of what she had just been doing. Instead, he splashed cold water on his face and got dressed. Meeting a normal-looking Scully a few minutes later.

That may have been the first time, but it definitely wasn't the last. Over time, he became fluent in Scully's arousal. On nights where he heard the rusting of the sheets and the sharp breaths, he would rake his hand down his body, slipping underneath the elastic waistband of his pyjamas, and firmly take hold of his erection. He would stroke himself in time with her pants, closing his eyes and pretending he was the cause, picturing her writhing underneath him. It was a perverse dance that absolutely thrilled him.

He slowly started to recognize when she got turned on in their daily life too. It's not like he had been oblivious to the female libido; he just hadn't considered it in regards to Scully. If he had a dollar for everytime he had to hide a boner or will himself not to get hard throughout the day, Mulder would be a rich man. He couldn't help it when he was constantly in such a close proximity to a beautiful woman he absolutely adored. He just didn't imagine she had to do the same.

They were on a case that required them both to squeeze into a small closet to look at some inscriptions. Scully went in first and Mulder followed, holding a flashlight in his hand. He hadn't been giving it much thought at the time, but looking back, he was invading her personal space. His front was almost flush against her back and he was leaning over to point to the marks on the wall, his breath fluttering the hair by her ear.

He had been asking her questions when, out of nowhere, she asked, "Mulder, is that a new cologne?" He was taken aback at the breathy question, and shined the light so he could get a better look at her face. He wanted to grin when he noticed the same features on her face as that night all those years ago. Her cheeks were flushed and her eyes were heavy-lidded and dilated.

"Yes, your mom bought it for me for Christmas," he answered, and on a suicidal impulse, he played naive to her condition and leaned into her, pressing his hardening bulge into the cushion of her ass. He felt her involuntarily jerk back into him as she sharply inhaled between gritted teeth.

Before he could celebrate, one of the crime scene technicians asked them a question, making them jump away from each other like a bunch of horny teenagers caught making out.

That night, he made the connection that she pleasured herself on nights that corresponded with excess flirting between the two of them. He continued to test this theory by getting closer during the days and sending more flirtatious comments than normal, always applauding himself when he heard her release that same night.

There were a few nights that he pretended to leave something in her room, or pretended that he got an update on the case, just so he could see a glimpse of Scully in the throws of passion. He had never been bolder beyond that, until tonight.

He grabbed himself in anticipation when he heard the first whimper, already rock hard from thinking about it. For about five minutes he played with himself from root to tip as he heard her try to muffle her sounds by crying out into a pillow. It wasn't effective.

He was playing with the precum leaking out of his head when he heard it. "M-mulder, ah!" He almost came on the spot. He sat up in bed and strained to hear it again. He had always fantasized that he was the cause of her nightly excavations, but he thought that's all it was: a fantasy. Actually hearing that breathless, pitched voice crying out his name was painfully erotic.

He felt his heart hammering in his chest. He felt emboldened with the newfound knowledge that Scully was definitely getting herself off to the thought of him. He got out of bed and walked to the door, giving himself a pep talk as he raised his fist to the door three separate times. This was more than just lust and he knew they both felt the same way, this was something he had always dreamed about and the tangibility of it scared him. After a moment, he finally knocked and he heard the same scrambling as all those times before.

"Mulder, What's wrong?" If he wasn't so aware of the cause, he would have laughed at the way her hair was sticking out in different directions.

Swallowing down any lingering anxiety, he tried to play cool. "I wanted to ask you the same thing, Scully. I could have sworn I just heard you call out my name." He had lowered his voice in an attempt to sound suave, a move he hadn't made in years, and he hoped it was coming across okay. With the way she was shifting, he wanted to say it was.

"I don't know what you're talking about," she was trying to use her no-nonsense voice, but the way her voice was quivering made this fail.

He leaned down a little bit so she was forced to look at him, "Oh really? Because I think you do."

She met his gaze and he saw his playful intentions mirrored back at him. "Want to share with the class?" She was prodding him back and they both knew it.

Taking the biggest risk of his life, he leaned in closer so that his mouth was grazing her ear and crooned, "I think you were touching yourself while thinking about me."

His hands immediately shot to the door frame to ground himself when, unexpectedly, he felt her dainty hand fully grasp his length. Her cheek pressed into his own as she smiled, crooning back, "You mean like you touch yourself when you listen to me?" Her fingers were working magic through his pants as they danced up and down his shaft, causing a throaty moan to escape his lips. She sensually laughed at this and hummed, "I think we both know how thin these walls are."

Removing his hands from the doorframe, he grabbed her biceps and pulled her flush to him, pressing his lips against hers in a fevered kiss. His heart leapt when he felt her return the kiss with equal vigor, removing her hands from his hard on and lacing them behind his neck, her velvety tongue felt like silk against his own. He removed his grasp from her arms and started exploring her body. From the dip of her waist to the heft of her breasts to the swell of her ass, the body he had spent years fantasizing about was finally under his hands. He only stopped his ministrations when Scully ground her pelvis into his with a desperate fervor. The overwhelming pleasure took his breath away and his jaw went slack, breaking the kiss.

He was glad that when his brain stopped functioning, Scully picked up the slack. Her lips moved from his mouth to his jaw to his neck, gently sucking while running her tongue along his skin. He was drunk off the sensations and she took advantage of his slack stance by dragging him by the shirt and pushing him onto the bed.

She placed one knee on either side of his hips and settled down on top of him. Grinning down at his awestruck expression, she grabbed the hem of her shirt and whipped it off with graceful agility. Seeing her exposed breasts provoked him back into action and he leaned up to take a pert nipple into his mouth. His rocking into an upward position caused their pelvis' to grind against each other with tantalizing friction and Scully threw her head back with a sinful moan.

As he ran his tongue back and forth against her nipple, his other hand was giving ample attention to her other breast, switching back and forth. After a few minutes, Scully was whimpering and rocking back and forth against his bulge.

He released her nipple with an audible 'pop', and grinned up at her slack-jawed expression. She smiled back at his, but quickly moved to remove his shirt. They had to seperate for a moment so they could take off their pants before she rolled back on top of him. He looked up at her in complete devotion and awe. Grabbing her hips, he asked, "Are you sure about this?"

She reached down in between them, grabbing his throbbing cock and rubbing it along her opening, coating it with her arousal. "I've been sure about this for years," she smirked, easing down on his length.

It took every fiber of his being not to buck into her tight heat. With every inch he got deeper into her, he was overwhelmed with the sensation of her gripping onto him. He was focused on her face as she sank down and was captivated by the look of pure pleasure dancing across her features. When she had taken him in fully, she wiggled against him, getting used to the feeling while also grinding her clit against his public bone. I'm the luckiest man in the world.

As if she heard his thoughts, she smiled down at him and placed another kiss to his lips as she started riding him. She was talented beyond his wildest fantasies. She broke off the kiss and he saw an erotic string of saliva break onto her chin. She sat up straighter, which allowed him to go impossibly deeper, and she rested her palms on his torso, so she had leverage to rock her body up and down his length. He thrust in tandem with her as he watched her brow furrow in pleasure and her breasts bounce on her chest.

He noticed she was closer than he had anticipated when she started whimpering and grinding even harder onto his public bone. Understanding her movements, he licked the pad of his thumb and brought it to the apex of her legs, circling the digit around her swollen clit. His ministrations caused her to cry out and grip painfully onto his middle.

With the way she was rotating her hips into his hand and the desperation in her thrusts, he knew she was close. He was a man on a mission now, and he wanted more than anything to see the look on her face when he made her cum. "Scully, open your eyes for me. I want to watch you when you cum." With heavy lids, she opened her eyes and looked at him in pure animalistic lust, it was the most sensual thing he had ever seen. "Fuck, you're so beautiful."

Within a few seconds, she went almost rigid on top of him, violently thrusting against him with an unrelenting vigor. "Ah-Mulder, oh my god," she cried out as her body convulsed. Hearing her call out his name like that almost sent him over the edge, but he was determined to make this as good for her as possible, so he used every ounce of restraint he had left to prevent himself from letting go. He watcher her with pure rapture, as her eyes nearly rolled into the back of her head, and her wetness was contracting around him. He kept circling her clit and thrusting into her to prolong her orgasm. She grabbed his wrist to signify she was overly sensitized and he returned his hands to her hips as she let out a satisfied laugh with a goofy smile.

She lethargically leaned down and pressed kisses along his jaw and nibbled his ear, he continued thrusting as she breathed into his ear, "Your turn." She started riding him with no abandon and he joined her, now having permission to let go. She was perched on top of him with a seductive smile as he bucked into her. He only lasted a few moments before he found release, burying himself inside of her and grinding in ecstasy while calling out her name like a hymn.

When he was finished, she rolled off of him and laid down right next to him, nuzzling against his spent frame. His normal eloquence and wit was lost, the only thing he could manage to say was, "wow."

"Wow's right," she chuckled back. He glanced down at her and his heart was warmed to see she was resting peacefully against his chest. She looked like an angel.

Her words from earlier rang in his ears and he recognized them with new meaning, "Wait, so you knew I could hear you through the walls?" He didn't think the smile on his face would ever fade.

He felt her grin against him and she mumbled sleepily, "Not at first, but the one time I heard you panting and the sound of the bed rocking ever so slightly and I figured it out. Then when it only happened every time I was, I really figured it out.

She didn't have to say it, it was implicit. She called out his name knowing he would hear it. She wanted this just as much as he did. He looked down at her and kissed her once again before falling asleep.

They never closed the adjoining door again.
