*I do not own anything. This is completely A/U

Ever since becoming Austin's girlfriend and having sex the week before, Ally had been consumed with thoughts of that night. She would be in the middle of reading or trying to fall asleep and would flash back to them tangled in her sheets. She found herself waking up, gasping more than once from remembered moments that invaded her dreams.

Because of this, she was rather irritable as the week went on. Lack of sleep combined with her inability to study found her in the back part of the library stacks on a Friday evening after coming back from the A&A Music Factory. She prided herself on being able to find the more out of the way places to study in the library and had found the perfect place in the back corners. Many times, when she couldn't study, she would go there and suddenly be able to concentrate. She was hoping that it would be the same as it usually is.

However, after being there for several hours, she didn't feel herself getting any closer to accomplishing her studying. thus, she found herself browsing the books near here. Ally's study nook was situated in the non-fiction section, her old friends. It also meant that she usually was by herself since people didn't really go to that section of the library.

She was running her fingers lightly over the book spines, hoping something would jump out at her. While looking, she was surprised to feel someone behind her. She felt her become indignant and whirled around to tell the person that there was no reason to be in her personal space. She found herself at a loss for words when she saw it was Austin

"What's wrong Ally? Cat got your tongue?" he smirked.

"No. I'm just surprised you know where the library is."

Austin chuckled. "Contrary to popular opinion, I do in fact know where the library is, as you can see. I just know where it is so I can avoid it at all costs."

"That doesn't explain why you're here though," she told him, arching an eyebrow.

"Ah, you got me Dawson. I've been consumed by thoughts of you and had to find you right this second so I could declare my undying love for you."

Ally bursts into laughter. "Has that worked for you before?"

"No," he admitted, "but it was my first time trying it out. Have to make sure I have fresh stuff for when I want to woo the ladies."

Ally didn't comment on that. Instead, she asked, "What's the real reason you're here, Austin?"

He leaned in close, placing his hands on the shelf by her head. He whispered in her ear, "Would you believe me if I told you I can't get you out of my mind and I just had to fuck you to do something about it?"

Ally felt her mouth go dry. Was he really having the same issues she was? She couldn't believe it. She realized he had started to say something else. "Whenever I close my all I can see is us in your bed and then I remember what you felt like and I completely lose my train of thought."

He then proceeded to press open mouthed kisses under her ear and made his way down her neck. Ally suddenly found her voice, "Really? Any plans to do something about it?" Austin pulled back and smirked at her. "Feeling bold today?" Ally blushed, but didn't say anything. Austin just grinned wider. "If that's how you want to play it, Dawson."

He then surprised her by pressing a bruising kiss onto her lips. He traced her lips with his tongue and she opened her mouth, allowing him to tangle his tongue with hers. Ally moved her hands up to tangle in Austin's hair, giving as good as she got. She felt one of his hands start to make its way under her black low-cut shirt and she pulled back. Before she could say anything, Austin said, "Relax Ally. No one will find us back here."

He immediately kissed her again, not giving her a change to voice her concerns and soon she forgot she what she was going to say anyways. Austin's hand continued its trek to her bra clad chest and cupped her breast, causing her to pull away and let out a breathy moan. Austin chuckled before catching her lips in a kiss again.

His hand continued to fondle her breast, pulling the cups of her bra down, allowing him direct access to her nipple. He flicked it several times before squeezing her entire breast. His other hand then started to make its trek down her stomach to the button on her jean skirt. Ally tensed and pulled back, looking at Austin with concern. He assured her, "Don't worry. I'm not going to undress you. We might get caught."

He chuckled as he captured her in a chaste kiss. "But, that doesn't mean that we can't still have some fun. What do you say Dawson?" he asked her after pulling back.

Ally couldn't find the words to respond, so she just pulled him back towards her and kissed him. Austin took that as permission and went back to the button on her skirt. He unsnapped it and lowered her zipper slightly before brushing his fingers under the waist band of her panties. Ally sucked in a shuddering breath as his fingers dipped further her underwear.

"Everything all right Ally?" Austin asked with a smirk. Ally decided that two could play that game and moved her hands to the button on his jeans, but Austin stopped her. "This isn't for me. This is just for you and my enjoyment"

Ally didn't quite understand, but moved her hands away from his jeans and Austin continued his explorations. He moved her jean skirt up her hips and his hand found its way into her underwear. He cupped her, groan at her wetness. "Excited about something?" he murmured in her ear.

All Ally could do was moan feeling his fingers lightly exploring her heat. Austin pressed a kiss to her neck as he pressed his fingers into her heat. He had her pinned against the shelves and she had nowhere to move. She was completely at her mercy.

"Jesus, Ally," Austin groaned. "You're so wet." Ally moaned in response. "You have to stay quiet," he admonished her when he realized she was getting a bit loud. "Think you can do that?"

Ally bit her lip to try to muffle the sound bubbling in her throat. Austin was rubbing light circles on Ally's clit as he lazily slid his fingers in and out of her vagina. She was getting frustrated at Austin's leisurely pace. "What are you waiting for?"

Austin smirked, "Impatient?"

"Possibly," she hedged.

"If my lady demands," he whispered in her ear before renewing his ministrations. "How's that?"

Ally's response was a muffled groan. Austin started to whisper in her ear the things he would do to her if given the opportunity and Ally felt herself getting closer to the end. Austin seemed to sense it as well as he pulled her into a searing kiss and curled his fingers. That pushed Ally over the edge and she clung to him as she rode out the waves.

After a few moments, she felt Austin removing his fingers from her underwear. She watched as he brought his fingers to his lips and licked one. "Seriously, Ally. I can't wait to taste you".

Ally blushed, entranced. Seeing her looking at him, he offered a finger and asked, "Want to see what you taste like?"

She actually wasn't sure she did but leaned forward slightly to lightly suck on his finger. His finger had a slight tang to it and something else she couldn't place. She assumed was her. She slowly pulled back, making a popping sound when she released his finger from her mouth. She looked in Austin's eyes and saw that they were darker than nor She took the opportunity to slip her hands down to the front of his jeans and cupped his erection through them.

He bucked into her hand, but quickly removed it. "Ah ah ah, Ally. I told you. It was about you."

"But, Austin—"she started.

"No buts. Don't worry about me."

Before she could respond, he pressed a hard kiss to her lips and walked away. As she watched his back, she wondered what had just happened. And she also thought that two could play that game.

It took her several days, but Ally was finally able to devise a plan to repay Austin for the library. Once he left, she was able to settle down and get some studying done. How later that night she realized that she didn't like that he hadn't let her return the favor. So that meant she had to take it upon herself to remedy that.

She spent a few days trying to figure out his schedule so she could see when a good ambush time was. She knew she didn't want to try anything during the day as that was asking to be caught. But, if she was able to get him at night, all the better.

Her chance finally came on Saturday, a week later, as Austin had surprisingly made his way to the library because of a test on Monday. Ally knew this was her chance.

She saw Austin walk into a private study room. She waited until he had been in there for a little while to give herself a small pep talk before making her way inside. Austin didn't glance up when she walked in, but he did when she closed the door with a soft click.

"Ally," he smiled. "What are you doing here?". Austin thought Ally looked adorable yet sexy with her tight floral dress and heels. Ally smiled, but didn't say anything. Austin's smile wavered. "Ally?"

Ally still didn't say anything as she made her way to his desk and straddled his lap, facing him. Austin's eyes widened at the turn of events before he smirked at her. "Something on your mind, Ally?"

She leaned in to kiss him lightly before placing her lips by his ear, "I think I owe you something."

She moved back far enough to see his face and was pleased with the slightly dazed look in his eyes. He seemed to shake himself out of it and asked, "And, just what do you owe me?"

"Something in return for last Friday night," she said before capturing his lips into another kiss, this one more forceful. Austin leaned back in his chair and Ally followed, not wanting to break their kiss. If their kiss broke she might pause to think too much about what could go wrong with this situation.

Unfortunately, the chairs in the library weren't that comfortable and they obviously weren't made for two people to sit on. So, Ally wasn't able to get as close to Austin as she wanted. But, it did make it easier for her to get her hands to the button and zipper on Austin's pants. She popped the button and tantalizingly slow lowered the zipper. She could feel Austin rising to the occasion.

She leaned back so she could see what she was doing. Unlike with when he was in control, she needed to see what she was doing to feel comfortable. She grabbed the edge his underwear and tugged slightly. "Lift your hips a little," she told him.

Austin obliged and she moved his pants and underwear down just enough to free him from the confines of them. "Happy to see me?" she joked.

"Oh, you have no idea, Ally," he breathed before pulling her down into a kiss.

As they kissed, she lightly ran her fingers up and down his length before grasping him. Austin pulled away and dropped his head back, letting a ragged moan escape his lips. Emboldened, Ally squeezed a little tighter and started to move her hand up and down, trying to pay attention to what he liked. This was uncharted territory for her as she had never tried anything like this with Dallas and she wanted to make sure she was doing it right.

New to it or not, Austin seemed to be enjoying what she was doing, especially when she grazed the head of his cock. That seemed to get an extra shiver out of him. She experimented a little for a few minutes before kissing him lightly.

Austin lifted his head and looked at her with lust filled eyes. "Am I doing okay?" Ally asked, mentally kicking herself once she asked the question. "You're doing more than okay, Ally," he assured her. "Can you show me what you like?" she nervously asked.

Austin smirked before wrapping his hand around hers, guiding her to the right pressure and speed. Once it seemed that she had the hang of it, he removed his hand, but watched what she was doing. She was fascinated by the entire process. Austin seemed to tense up and breathed quicker. She started to notice his stomach was tightening and unconsciously sped her movements up.

Austin knew this wasn't how he wanted to go. Austin grabbed her wrist with his left hand and his right hand started to move up her thigh.

Since Ally was straddling him in her tight dress, Austin had easy access to her.

His thumb trails over her lace covered core, finding her damp. Ally kissed his lips, her breathing coming in broken pants as he presses beyond the barrier to touch her. Wit growl, he forces two fingers into her molten body.

"Are you sure this is a good idea?" she asks between kisses. "We could get loud..." God, she knew she would get loud for him. Moaning and screaming. Only for him. Austin still remembered giving her her first orgasm a few weeks ago. The look on her face. The fit of uncontrollable giggles that followed. How he'd practically begged her to let him do it again. And again. He could be between her incredible legs, feeling her shudder against and around him.

Ally's eyes closes as Austin's mouth finds her neck. His tongue smoothes over her pulse point teasingly. In a seductive voice, he whispers "Guess we'll just have to be quiet then..."

Scrambling, they fumble with the foil condom packet. The wrapper quickly discarded, it slips between the cushion and the arm of the chair, probably would be found later by janitorial staff.

Austin pushes her lace panties to the side. He throbs as she surrounds him, unable to take his full length due to his position in the overstuffed seat. Gripping her thighs, he urges her to ride. Shallow thrusts aren't nearly enough and he inches forward, causing Ally's body to sink further onto his own.

Her breathing is rapid. So many sensations assault her senses. Being in public and the threat of getting caught. The rasp of his pants against the soft skin of her inner thighs. It's maddening. Riding him at home, the hair on his body tickling her aroused skin was incredible. But this? This adds a whole other level. She needs more. More this, and of him.

Using her knees, she pushes up before sliding over him again. Her skin is on fire, heat radiating from her abdomen. When he arcs up bracing his elbows against the arms of the chair, her world implodes as he hits her sweet spot.

Austin's mouth latches greedily over Ally's, barely swallowing her moan. He feels her body clamping around his - feels the rush of fluid when he hits her just right. His jaw straining as he works her up one more time to share in his own high.

In a tangle of tongues, he anchors her mouth under his as his hand fists in her hair. He flattens the palm of his other against her lower back, forcing her body as far onto his possible. He stiffens, his features contorting in pleasure as he holds her close.

Ally's arms wind around his neck. She kisses his jaw as they both work to calm their breathing. Sighing as Austin brushes her hair from her face, she relaxes into his embrace

"That had to be one of the hottest things I have ever done, Ally," he panted once he pulled back.

"Happy to be of service," she giggled.

She looked at his stomach. "If you give me a second, I can get some tissues to clean up."

"That would be great, thanks."

She walked to her bag to retrieve a pack of tissues and brought them to her. She watched as Austin took off the condom and throwing it away in the trash. He then quickly tucked himself into his pants before zipping back up.

"What do you say to dinner, Ally?" "I would love that". Austin slung his arm around her shoulder, leading her out of the library into the evening.
