Erin was very surprised to find that David had agreed to come with her to the Library of Congress on one of his rare days off from the BAU. She had wanted to get some more research done on her genealogy. Tabitha had been asking about their roots, and she realized that she didn't know all that much, beyond the fact that her mother's family was as English as the day was long.
"I made us reservations for three. We can always come back another time," he said as he took a seat next to her. There weren't very many people in the reading room yet, which pleased her, since she really wanted to get some work done, having done a few days research beforehand as had been suggested on their website. Smiling, she nodded and pulled her list of ancestors that she wanted to know more about out of her purse. "What do you need me to do?"
He was being a little too helpful in that moment, and she gave him a searching look as she pulled out a second notebook, handing it over to David. "I need you to go pull the first two of these books. I know that they're available to the public, so we won't have to ask a librarian to pull them for us. Hurry back to me, okay? I want to get as much done as possible before we head out to lunch."
"All right, darling." He bent down and kissed her gently before disappearing out into the library. As soon as he was gone, Erin began to set up her laptop, knowing that she would have to enter whatever she found in her family tree program. It was going to be a long few hours of looking up information in their databases, finding the correct book, and then plugging the pertinent information into her tree. A part of her hoped to find out that she was related to someone famous, but she knew that that was more a pipe dream than anything.
She had just found her way into a flow when David returned with the books she'd asked for, and she glanced up at him with a glare at having been interrupted. "Did you have to be so loud?" she groused as she picked up the first book and opened it, scanning the table of contents to find the chapter she wanted to look at.
He shrugged a little before giving her a cheeky wink. "There's no one else in the room, so I didn't think that I needed to be a little church mouse," he replied as he took a seat next to her at the desk. She rolled her eyes lightly as she turned her attention back to the book and began to read the information presented there. A part of Erin wasn't surprised when David scooted his chair closer to hers, and she knocked her elbow into his side when she turned the page.
That didn't deter him from doing his best to distract her, as the next thing she knew, he was lightly dragging his fingertip up and down her forearm, making her shiver with desire. She glanced at him out of the corner of her eye, and he winked once more. "Is there a problem, bella?" he asked, trying to sound completely innocent.
Erin nodded as she looked pointedly at his hand. "You are driving me to distraction, and if you keep it up, it will take us twice as long here, and we'll miss our reservations."
He smirked at her before leaning in and whispering in her ear. "Maybe I want to keep you all hot and bothered. Maybe I like the way your cheeks flush when you're aroused and distracted. Maybe I want to see how far we can take this without getting thrown in jail." At the end of his words, he traced the shell of her tongue with his ear, making her shiver once more as she shifted in her chair. Desire was quickly pooling in her, and she knew that she would have to actively discourage him from doing anything particularly suggestive, since that could very well get them kicked out for the day, if not permanently.
He didn't seem to catch on to what she was thinking, as he was still leaning in close to her, softly blowing in her ear, which was driving her to distraction. After she'd read the same sentence six times, David slipped his hand over and brushed his knuckles against her breast. Erin shifted in her chair once more, trying to ignore the feeling of her nipples stiffening into a tight peak beneath the light touches of his hand. "David!" she squeaked out when he caught that nipple between his fingers, squeezing it while his thumb brushed against her sensitized flesh.
"We're still alone, Erin. Relax. I know when to back off."
She let out a heavy sigh as she shook her head and redoubled her efforts to read the information, starting to take notes on the pad of paper next to the book. He seemed to take this as a challenge, since he squeezed her nipple a few more times, his thumb starting to make lazy circles around the very tip. Erin frowned as her hand jerked a little, dropping her pen onto the floor, and she scooted back from the desk she was sat at in order to pick it up.
David was quicker to react, however, and he slipped off his chair to kneel on the floor, grabbing the pen and then looking up at her with a cheeky grin. Erin shook her head at him, desire warring with anxiety in her heart. He nodded and handed the pen up to her before moving between her legs and running his hands up and down her thighs beneath her skirt. "David," she said lowly, trying to sound pleading.
"Shh, Erin, you don't want to attract attention to us, now do you?" he said as he hooked his thumbs into the waistband of her underwear and started to tug them off her body. And though she knew that she could put a stop to this by simply not moving for him, her body instinctively shifted, lifting her hips and ass upwards so that he could pull them the rest of the way off her body. Once she was bare to him, Erin knew that she would have to appear as if she was unbothered by what he was doing with her, since she couldn't draw attention to them and risk a ban from the institution.
David must have sensed her capitulation, since he let out a quiet chuckle as he spread her legs apart and fitted his body more closely between them. She swallowed a moan as his hand brushed against her vulva, and then he was slipping his blunt thumb between her labia to find her clit, stroking it slowly. Erin coughed to cover up her slightly louder moan, and he pressed his mouth against her inner thigh in reaction. His laughter felt so sensual against her skin, and she shivered as she shifted in her chair once more, canting her hips in such a way so to make it easier for him to take things to the next level. David peppered her inner thighs with soft kisses, his goatee tickling her sensitive skin, and she sighed a little as he made his way closer and closer to her core.
The moment he started to eat her out in earnest, the door to the room opened, and she gasped a little as she fought not to react to the woman coming towards her. Thankfully, the new person took a seat on the far side of the room, and Erin relaxed a little, letting David continue to arouse her. It was so difficult to ignore the way that David was using his tongue and fingers to get her off, but she did her level best, knowing they couldn't afford to get caught now more than ever.
Erin bit her cheek as hard as she dared when her orgasm came, washing over her in large waves. She slipped one hand off the desk and buried her hand in David's hair, digging in firmly as she breathed heavily through the orgasm. He chuckled against her body, and she shook her head a little as he moved away from her, resting his head on her knee as they both got control of themselves once more. The woman who'd joined them got up a few moments later and left the room, and Erin slumped in her chair as she motioned for David to move out from under her desk.
"That was a little too close, darling," she purred as he took his seat next to her once more, wiping delicately at his face with his handkerchief.
"But that made the thrill all the more fulfilling, right?" he asked as he shoved the square of fabric into his pocket.
Erin shook her head as she smirked at him. "Yes. Though I think that we should maybe hold off on our next little adventure. I don't think that my heart could take another close call like this so soon." He went to reply when the door opened again, the same woman coming inside. She gave them a second glance, and Erin smiled at her before speaking. "Thank you for getting my pen, David. I can't belive that it fell so far back!"
"You're welcome, Erin." He leaned over and pecked her cheek before smiling at the woman and sitting back in his chair. Erin just let out a quiet sigh as she got back to work, trying to think about where she could take things for their next adventure, knowing that it would have to have higher stakes than this. It would be hard to top, but she knew that she could do it, if she really thought about it.
